Abstract (en)
[origin: ES486350A1] A cartridge for housing a daisy wheel print element during printing use and non-use. The cartridge has a front, sides, and a back, and is structured to substantially enclose the print element. Included in the makeup of the cartridge are (1) a slot in the top of the front for accommodating a print hammer during printing operations, (2) an orientation opening generally centralized within the front to accept a matching orientation protrusion carried by the print element, (3) a loading opening in the bottom for insertion and removal of the print element, (4) a card holder carried by the top of the back, (5) a ribbon guide carried by the top of the front, and (6) a center bowed leaf spring located within the cartridge. The lower end of the spring acts against the lower inside of the back and the bow acts against the inside of the front adjacent the orientation opening. As such, a ramp is provided for caming the orientation protrusion toward the orientation opening during insertion of the print element into the cartridge. Upon engagement of the orientation opening and orientation protrusion, the spring then serves to maintain the print element latched in a desired rotational position.
