[0001] The present invention relates, in general, to reproduction apparatus, and relates,
more specifically, to electrographic reproduction apparatus having multiple means
for feature selection or adjustment.
[0002] Electrographic reproduction apparatus are provided with an operator control panel
for allowing an operator to program the apparatus for a reproduction run. In its simplest
form, the control panel includes several dedicated (hard) buttons and switches for
selecting features for a reproduction run, as well as visual indicators for informing
the operator which features were selected. The operator control panel can also have
a display for displaying messages. The control panel also includes keys and buttons
for altering the display to indicate selected options. (See, for example, US-A-5,113,222.)
The display may also include a touchscreen overlay having "soft buttons" for providing
operator input to the reproduction apparatus. (See, for example, US-A-5,045,880; US-A-5,061,958;
US-A-5,105,220; US-A-5,049,931; and US-A-5,010,551.)
[0003] A problem arises when all of the selections or adjustments for a particular feature
cannot be displayed as touch areas within the optimal area range. In such a case,
there is not enough room on the screen to display all selections (or adjustments)
as touch buttons. Yet there is a need to maintain a consistent interface with the
reproduction apparatus where the user selects a feature by touching that feature's
soft button. Although the latter patents disclosing a touch screen user interface
include both soft button input and feature scrolling with select button input, there
is no disclosure of combining the two types of user interface for alternate selection
of the same feature.
[0004] According to the present invention, there is provided a solution to the problems
of the prior art by providing multiple means for selecting a feature in a touch screen
user input to a reproduction apparatus.
[0005] According to a feature of the present invention, there is provided in a reproduction
apparatus having a plurality of selectable features for carrying out a reproduction
run, an operator control panel for providing operator interface for controlling said
reproduction apparatus comprising:
a display for displaying at least one selectable feature for a reproduction run
with plural displayed options for said at least one selectable feature;
a touchscreen overlaying said at least one selectable feature and having operator
actuable touch areas overlaying said plural displayed options for providing operator
input to said reproduction apparatus to select one of said feature options; and
a scroll touch button on said touchscreen for scrolling a visual indicator to highlight
one of the feature options for said at least one selectable feature;
wherein a feature option of said at least one selectable feature can be selected
either by touching said touch area associated therewith or by actuating said scroll
button to select said feature option.
[0006] According to another feature of the present invention there is provided in a reproduction
apparatus having a plurality of selectable features for carrying out a reproduction

actuable touch areas overlaying said plural displayed options for each said at least
two selectable features for providing operator input to said reproduction apparatus
to select one or more feature options, wherein said touch areas are substantially
larger for one of said selectable features then for the other of said selectable features;
and
a scroll button on said touchscreen for scrolling an indicator to identify one
of the feature options for said other of said selectable features;
wherein a feature option of said one selectable feature is selected only by touching
said touch area associated therewith; and
wherein a feature option of said other selectable feature can be selected either

for incorporating the present invention.
[0008] Figure 2 is a schematic diagram of the electrographic reproduction apparatus of Figure
1.
[0009] Figure 3 is a diagrammatic view of an operator control panel, including a display
with a touchscreen.
[0010] Figures 4-7 are respective screens useful in explaining the present invention.
[0011] Because electrographic reproduction apparatus 1 are well-known, the present description
will be directed, in particular, to elements forming part of or cooperating more directly
with the present invention. Apparatus not specifically shown or described herein are
selectable from those known in the prior art. Particular reference is made to US-A-4,740,818
and US-A-5,113,222, the contents of which are incorporated herein by reference.
[0012] With reference now to Figure 1, there is shown an electrographic reproduction apparatus
1 having a recirculating document feeder 50 that includes a tray portion for accepting
a multi-sheet document original for reproduction. The apparatus 1 includes an operator
control panel (OCP) which, as will be described, includes buttons and prompting displays
for facilitating a job setup, that is, the input of an instruction set to the apparatus
logic and control unit (LCU) to enable it to control a series of operations resulting
in a desired copy output representing a reproduction of the document originals. Copies
may be produced on receiver sheets stored in either or both drawers holding trays
23a and 23b. The copy output from the apparatus is stored either in an exit tray (ET)
or finisher/sorter (F/S) having a series of sorter bins, as is well known.
[0013] Referring now to Figure 2, the electrographic reproduction apparatus of Figure 1
incorporating the present invention will be described in greater detail. As shown,
reproduction apparatus 1 includes a photoconductive web 5 that is trained about six
transport rollers 10, 11, 12, 13, 14 and 15, thereby forming an endless or continuous
web. Roller 10 is coupled to a drive motor M in a conventional manner. Motor M is
connected to a source of potential V when a switch SW is closed by a logic and control
unit (LCU) 31. When the switch SW is closed, the roller 10 is driven by the motor
M and moves the web 5 in clockwise direction as indicated by arrow A. This movement
causes successive image areas of web 5 to sequentially pass a series of work stations
of the apparatus 1. These workstations include: a charging station 17,17a at which
the photoconductive surface 9 of the web 5 is sensitized by applying to such surface
a uniform electrostatic charge of a predetermined voltage; an exposure station 18
at which a light image of a document sheet S, supported on transparent platen 2, is
projected by mirrors 6, 8 and lens 7 onto the photoconductive surface 9 of the web
5 to produce a latent electrostatic image of the document sheet. Also included are
a magnetic brush development station 19 at which the latent image is developed with
developer which may consist of iron carrier particles and electroscopic toner particles
with an electrostatic charge opposite to that of the latent electrostatic image, to
form a toner image on web 5. A transfer station, including a corona charger 21 transfers
the toner image on web 5 to a copy sheet S' which is transported to a heated pressure
roller fuser 27 where the toner image is fixed to copy sheet S'. The sheet S' containing
a fixed toner image is fed to a finisher/sorter or a top exit tray.
[0014] A cleaning station 25 is provided to clean the photoconductive surface 9 of web 5
of any residual toner particles remaining after the toner images have been transferred.
[0015] Copy sheet S' is fed from one of supplies 23a or 23b to continuously driven rollers
20 which urge sheet S' against a rotating registration finger 29 of a copy sheet registration
mechanism 22, from which it is fed to the transfer station 21.
[0016] Apparatus 1 includes an additional color development station 19a, a duplex tray DT
and a digitizer, including digitizer tablet 52, wand 54 and circuit 56 which provide
digital signals to LCU 31.
[0017] Referring now to Figure 3, there is shown an operator control panel (OCP) which includes
a set 100 of dedicated "hard" buttons or keys and a touchscreen display 104 to allow
operator input and control of apparatus 1. The touchscreen display 104 includes (1)
a known programmable type display wherein LCU 31 includes a computer program and a
bit map memory for controlling the representation that is visible on the display and
(2) a touchscreen which overlays the display. The touchscreen is an operator input
device having operator actuable "soft" buttons and areas for providing operator input
to the reproduction apparatus. Touchscreens are well known and include resistive,
acoustic, and infrared type input technologies.
[0018] The operator selectable set of hard buttons on the left include, START, JOB INTERRUPT,
and STOP buttons. In the middle are numerical buttons 0-9 to set the number of copies
or sets to be copied. A * and CE (clear entry) buttons are also included. On the right
are the following hard buttons; JOB LEVEL, PAGE LEVEL, MEMORY, PROOF, LANGUAGE, SUMMARY,
INFORMATION and RESET. The INFORMATION (i) button accesses an information system (stored
in memory in LCU 31) which provides detailed information about reproduction apparatus
1 including features selectable by the operator and messages which are displayed on
touchscreen display 104.
[0019] As shown in Figure 3, the screen illustrated on the touchscreen display is referred
to as the "standard features" screen as it displays various features that a casual
user of the apparatus 1 would want when first approaching the apparatus for an average
reproduction run. The screen includes a message display area 106, a copies or sets
requested display area 105, a copies or sets completed display area 107, and a "soft"
button area 108. The "soft" button area includes selectable features with plural displayed
options for each feature. The features shown are original copy, collate, paper supply,
copy quality, reduce/enlarge, exit, staple. The plural selected options for each feature
are provided with operator actuable soft buttons overlaying the displayed feature
options. The selected feature option is highlighted.
[0020] The copy quality and reduce/enlarge features are provided with respective scroll
buttons 110,112 for scrolling through the feature options. The feature options are
sequentially highlighted during scrolling. The reduce/enlarge feature also includes
a zoom option 114 with scroll buttons 116.
[0021] Certain feature options may also be locked out to the operator, although displayed.
Such feature option (for example, the "finisher unlock" option under the "exit" feature
shown in Figure 3) is highlighted in a different manner than highlighted feature options.
[0022] Ideally, touchscreen technology allows for any area on the screen to be defined as
an "active" or "touch" area. It has been found that optimally, "touch" areas to be
used for user/operator input be no smaller than 13mm x 13mm to easily accommodate
a finger tip. A problem arises when all of the selections or feature options cannot
be displayed as "touch" areas within the optimal size range. In such a case, there
is not enough room on the touch screen to display all selections as "touch Buttons".
Yet there is a need to maintain a consistent interface where the user selects a feature
by touching that feature's button.
[0023] According to the present invention, there is provided a solution to this problem
by providing two methods for the user to make a feature selection, in the case where
all selections can not be represented by a touch button that meets the optimal touch
area size requirements. One method (illustrated with reference to Figs. 4 and 5) uses
a scrolling operation and the other method (illustrated with reference to Figs. 6
and 7) uses a direct selection operation.
[0024] The first method for feature selection uses a step-wise progression through the feature
options. Scroll buttons are provided as a means of navigating through the selections.
As shown in Fig. 4, touch screen 200 displays several selectable features for carrying
out a production run on a copier. Each of the features have one or more operator selectable
options. For features such as "original copy", "collate", "paper supply", and so forth,
the options are few enough in number to allow the option touch "buttons" (such as,
buttons 202, 204, 206) to have an optimal area size. For features, however, such as
"copy quality", and "reduce/enlarge", the options are numerous enough to prevent the
use of such optimal area size touch buttons. Instead, each displayed option has a
smaller touch area (such as touch areas 208 and 210), and each such feature is provided
with scroll touch buttons (such as buttons 212 and 214) for scrolling a visual indicator
through the feature options to highlight an option to be selected. As illustrated
in Fig. 4, the option labeled "5" under the "copy quality" feature is highlighted.
Using the scroll operation, the operator touches scroll button 212, to highlight the
selected option, which is the next lower option. This operation is depicted by the
circled numbers 1-3.
[0025] Figure 5 depicts an alternate scrolling format in which the feature/selection options
are arrayed in a matrix 220 of rows and columns. The specific feature depicted is
a job (reproduction run) having preselected reproduction features. The matrix depicts
job numbers which are stored in an internal memory. A scroll touch button 222 scrolls
through the matrix either row by row from left to right or column by column. The circled
numbers 1-3 depict the steps to scroll from a "previous" job to a "current" job.
[0026] Although the scrolling method for feature selection allows the operator to access
all of the feature options, it is necessary to step through preceding selections in
the list or matrix to reach the desired selection. The second method for feature selection
provides a direct path to the desired feature selection. Instead of using the scroll
buttons to step through the selections, the operator need only touch the feature option
within the array of options. This method is illustrated in Figures 6 and 7, which
correspond to Figures 4 and 5. This method obviates the need to scroll through the
previous list of feature options. It is, in essence, a short-cut provided for the
more experienced operator.
