BACKGROUND OF THE INVENTION
[0001] The invention relates to an automated vending machine for the recording and delivery
of messages or presentations on video cassettes.
[0002] Automated vending machines for the rapid production of black-and-white or colour
photographs, referred to as "fotomats", have been in popular use for many years. Such
machines allow the customer to record his or her image on a photograph, without the
necessity of a human photographer, by entering a small booth, inserting the required
amount of money, posing for the camera and waiting a short period of time to receive
the developed photographs. The booths are placed in locations having heavy traffic
such as shopping malls and amusement parks. Such photographs have been popular for
recording a special event but do not allow for an audio component nor for a moving
image.
[0003] Video cassette records (VCR's) which are capable of playing or recording moving video
images and an audio track onto VHS or BETA format video cassettes have, in a short
period of time, become a standard part of the domestic entertainment centre of the
average consumer in many countries. While initially VCR's were used primarily to display
prerecorded video cassettes, relatively inexpensive video cameras or "camcorders"
have also become a popular consumer item and the use of such cameras to record important
events such as births or weddings onto video cassette to be mailed to another family
member for viewing on his or her VCR has also become common. To date, however, there
has not been available an automated vending machine comparable to the "fotomat for
producing video cassette recordings. It is therefore an object of the invention to
provide an automated machine to allow a customer, upon tendering of a cash payment
or credit card, to record a video message onto a video cassette and to deliver the
cassette to the customer without the need for a human operator.
SUMMARY OF THE INVENTION
[0004] The present invention provides an automated vending machine for the production of
videotaped messages or presentations which comprises a mobile booth to accommodate
a subject customer, a video camera, a video cassette recorder, an automated unit for
handling and delivering the subject video cassette, a video monitor and video disk
player for instructing the customer, apparatus for handling payment by the customer
by cash or credit card, and a central processing unit for controlling the various
operations of the machine.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0006] With reference to the drawings, the apparatus of the invention is shown as a self-contained
booth or kiosk 10 which can be readily transported to the desired vending location.
The kiosk consists primarily of two independent pods, an equipment pod 12 and the
recording pod 14 which houses the customer seating. The division of the kiosk into
the two pods facilitates the servicing of the electrical equipment. The two pods can
be locked together to discourage theft or vandalism of the unit.
[0007] As shown in Figs. 5 and 8, the recording pod 14 is mounted on frame 16 and rests
on four circular feet 24 attached to the frame. The equipment pod 12 rests on four
wheels 22 which allow easy movement of the equipment pod for servicing.
[0008] As shown in Figs. 1-7, the recording pod has a skylight 33, two door openings 30
which are opened or closed using semi-circular sliding doors 32 (described in more
detail below) which have windows 35. The recording pod has a seat 36 for two customers
37 facing toward the equipment pod. An external video monitor 38, shown in Fig. 1,
and external speaker 40 are provided to attract the customer with a prerecorded video
and audio message originating on a video disc player within the unit, explaining the
nature and operation of the machine.
[0009] With reference to Fig. 6, the customer 37 is shown seated on seat 36 in position
for recording. A video camera 44 is located in the equipment pod at approximately
eye level and is separated from the customer by a half-silvered mirror 46 so that
the customer is able to see the image of himself or herself which is being recorded.
The camera 44 is connected to a VCR 60 which is supplied with a video cassette for
recording for the customer by cassette handling apparatus 62 to be described in further
detail below. An internal speaker 42 is also provided for the audio track of the instruction
video.
[0010] The control panel is located at 48 and includes a tele-prompter video monitor 50,
a credit card reader 52, (see Fig. 9), a bill reader 54, a coin collecting slot 56,
a change dispenser 58 and the video cassette outlet chute 11.
[0011] The sliding doors 32, as shown in Fig. 3, have a semi-circular forward upper edge
portion 18 which has rotatably mounted along the upper inner edge thereof a series
of rollers which roll in a track in the upper forward semi-circular edge of the recording
pod. In this way, a sliding door is provided which does not reduce the compactness
of the unit.
CASSETTE HANDLING SYSTEM
[0012] The cassette handling system 62 is described with reference to Fig. 10 through 21.
Overall control of the cassette handler is carried out by a programmable logic controller
69 such as the Allen Bradley Programmable Logic Controller which uses a ladder diagram
programming format to sense switch positions at various locations in the handler and
provide power to several electric motors which drive the different mechanisms described
as follows. The controller itself is controlled by the overall system logic, as well
as a local manual control panel which is used during maintenance and cassette refilling.
Most switches are dry contact micro-switch devices. Optical emitters and sensors are
required to sense the top cassette layer in the bin as described below. Conventional
retro-reflective sensors are used to detect cassette orientation at the top chute.
[0013] The handling system has a bin 64 containing a supply of video cassettes 13 with capacity
for 12 cassettes per layer, supported on a flat elevator platform 66 and one within
chute 68. Access to the bin for filling is through hinged door 65 which also carries
the upper part of chute 68. The top plate 69 of the bin carries pusher mechanisms
71 and 73 which move the cassettes in the topmost row to the top of chute 68, and
elevator motor 75 which raises elevator platform 66 on four steel cables by a pulley
system (shown in Fig. 15). Elevator platform 66 rides up and down inside the bin carrying
the cassettes which are separated by two vertical dividers 67 running from front to
back in the bin. Thus, as shown in Fig. 11, the bin consists of three vertical sections.
[0014] During operation, cassettes from the topmost layer are pushed onto the top of a stack
held in chute 68 leading down to the loader 70. As each layer is exhausted, the elevator
platform 66 is raised to allow movement of the next layer into the chute. Pusher 71,
shown in Fig. 13, is the side pusher and it pushes the cassettes in the top row in
the direction of arrow A. It consists simply of a right angle section blade 72 driven
via a timing belt drive 74 by a 110 volt AC gearmotor 76 (all motors described in
the handler are of this type, other than the elevator motor). Belt tension is maintained
by a spring-loaded idler wheel mount which allows the belt to slip should a jam occur.
The controller 69 senses time out condition in the event of a jam and stops the motor
74 after the time required to reach the next limit switch. A jam detect switch may
also be located against the sprung loaded arm if necessary. The linear slide which
carries blade 72 is a single block of a plastic material with lubricant filler, such
as NYLATRON, which slides within the outer C-channel 61 of the bin and a slot in the
top plate 69. Side pusher 71 pushes four cassettes at a time, moving consecutively
to positions determined by three limit switches located on the top plate and corresponding
to the position of the vertical dividers and the "home" side farthest from the chute.
[0015] Chute pusher 73 operates using the same mechanisms as side pusher 71, and has blade
85, motor 77 and belt 79. It pushes one cassette at a time onto the top of the stack
in chute 68 where a microswitch senses the presence or absence of a cassette and activates
the motor as necessary via the controller.
[0016] The elevator (shown in Figs. 14 and 15) consists of a flat horizontal platform 66
running up and down in the bin constrained by four wheels 67 located in the bin sides.
Platform 66 is supported by steel cables 78 running up to a lead screw system on the
top plate. The elevator platform consists of three separate plates resting on two
transverse stringers that carry the wheels and cable terminations on their outer ends.
The plates are staggered slightly vertically to ensure jam-free movement by the side
pusher, with the vertical dividers passing between the plates.
[0017] The elevator drive mechanism consists of a pulley block 81 riding on a lead screw
83 driven by a 110 volt AC reversible motor 75. The lead screw used in the preferred
embodiment was a 1" diameter, .2" pitch ACME thread unit which provides fail safe
locking against backwards rotation under load. Pulley block 81 acts on upper and lower
cables 78a and 78b which in turn are pulled around a system of pulley 90 to raise
or lower the ends of the cables 78. Cable length adjusters are provided on three of
the four cable ends to allow levelling of the platform. Torque reaction on the pulley
block is counteracted by a single bearing riding in a channel on the rear side of
the bin. Vertical travel control of the elevator is achieved using several sensors.
[0018] Optical sensors determine that the top layer is completely empty before raising the
elevator. Three light emitting diodes (not shown) are used to emit light across the
top layer and sense its reflection when the path is empty. Lack of a cassette in the
back left-hand position signals the elevator to be raised unless any of the other
positions is occupied, in which case a jam condition is indicated.
[0019] At the bottom of the cassette stack in the chute 68, the loader 70 extracts the lowest
cassette, checks the orientation, and if appropriate presents the cassette to the
VCR 60. Subsequently, the recorded cassette is retrieved from the VCR and passed out
to the customer via outlet chute. Improperly oriented cassettes are rejected out the
bottom of the outlet chute to an internal waste bin. The loader mechanism 70 has a
main base plate 80 which carries all the other components and hinges downwardly along
its front edge to permit the cassette to slide into the outlet chute. As the base
is rotated downwardly, the cassettes in the chute are lowered by gravity to allow
withdrawal of the next available cassette.
[0020] Mounted off the base plate 80 are the base tipper mechanism 82, the extractor mechanism
84 and the conveyor 86 which moves each cassette to and from the VCR. The extractor
consists of a linear slide assembly 104 that pushes the lowest cassette out of the
chute and simultaneously positions a roller 108 and two wheels 109 under the next
cassette in the chute to support the weight of those cassettes remaining in the chute.
The wheels are positioned by spring loaded pin devices that locate them under the
left and right edges of the cassette as the slide moves the cassette out, with the
roller providing intermediate support towards the end of the travel. The linear slide
is the same design of sliding block and timing belt drive as described above for the
bin pusher assemblies, with motor 106 driving a belt in channel 107. Jam protection
is also provided by a spring-loaded idler. Cassette orientation is sensed by micro-switch
detection of the slot present in the bottom surface of all cassettes. Incorrectly
oriented cassettes are directed to the outlet chute and thence diverted to the waste
bin by a solenoid-actutated flap.
[0021] The conveyor 82 is a belt drive consisting of motor 93, gear 94 and belt 95 which
propels the cassette to and from the VCR. In order to slide the cassette sideways
under the conveyor belt 95, the belt must be tilted upwards and this is done by pivoting
the entire conveyor unit on a horizontal axis 96 using the torque reaction from the
motor gear drive to either raise the conveyor end or lower it onto the cassette. The
cassette is guided at the sides to ensure proper mating with the VCR entrance slot.
After recording, the cassette is returned to the base plate for delivery to the outlet
chute 11 by the base tipper mechanism.
[0022] The base tipper mechanism 82 locks the base plate in the horizontal position, releases
the lock to allow the base plate to fall through 45 degrees with the motion cushioned
by a hydraulic or pneumatic dashpot (not shown) and subsequently raises the plate
back up to the horizontal position after retraction of the extraction wheels and roller.
A one-way clutch bearing 97 allows only counter-clockwise rotation of the shaft carrying
the link-wheel and link which supports the base plate. This shaft is driven by a timing
belt drive 99 from a motor 98 and in the "up" position holds the base plate horizontal
because backwards rotation of the shaft is prevented. When it is desired to release
the plate, the link-wheel 100 is rotated approximately 7,5 degrees counter-clockwise
and then the link 101 and base plate are free to fall on the overrunning clutch. A
second clutch 97 allows overrunning of the shaft 102 in the driven timing pulley to
prevent damage to the motor gearbox. The downards fall of the plate is controlled
by either an ENIDINE hydraulic damper or an AIRPOT air damper. The plate 80 is returned
to the horizontal position by further rotation of the link wheel 100 after the extractor
mechanism 84 has returned to its "home" position.
[0023] In operation, the attract sequence stored on the video disc player is played continuously
on the external monitor and speaker until a customer enters the kiosk and initiates
the recording sequence by pressing the appropriate start button. This causes the external
monitor to indicate that the booth is occupied and initiates a prerecorded instructional
message on the interior monitor. The customer is presented with the option of payment
by cash or credit card and selects the desired length of the recording and whether
delivery is to be included in the service. The central processing unit calculates
the appropriate charge and the customer either inserts a credit card in the credit
card reader or inserts the appropriate amount of money into a coin accepter or bill
reader.
[0024] The recording sequence is then initiated and the customer follows screen prompts
in order to commence the recording, pause, or end the recording. During the recording
the time remaining on the recording is displayed on the monitor. When the recording
is complete, the video cassette is ejected down outlet chute 11 by the cassette handler
to the customer and a receipt is issued to be used in the event that the customer
has paid for delivery of the cassette. In that event the customer will address the
cassette to the recipient and deposit it in slot 17 in the rear of the recording pod
for storage in location 45 (shown in Fig. 6).
