Abstract
A daisy wheel printer print package including a daisy wheel print element and a cartridge. The cartridge is adapted to have the print element inserted thereinto and maintained in a latched and properly oriented position for either acceptance by a printer or storage and shipping. When the package is installed in a printer, the print element is adapted to be unlatched for rotation within the cartridge for printing. Also, the cartridge is adapted to have the print element unlatched and removed therefrom.
Claims39
A daisy wheel printer print package comprising in combination:
- (a) a daisy wheel print element having an orientation protrusion on one side thereof;
- and
- (b) a cartridge (1) made up of a front, a back and sides, wherein said front has an upper portion including ramps which taper upwardly from adjacent said sides, (2) having an open bottom for insertion and removal of said element, (3) substantially enclosing both sides of said element during printing use and non-use, and (4) having a matching opening located in said front for accepting said protrusion for maintaining said element rotationally oriented in one position during printing non-use, wherein said front includes a hammer slot and said back includes a cardholder having a type opening generally aligned with said hammer slot.
A daisy wheel printer print package comprising in combination:
- (a) a daisy wheel print element rotationally positionable for printing use and non-use and including means for facilitating orientation of said element;
- and
- (b) a cartridge for housing said print element, said cartridge including means for facilitating orientation of said element, both said orientation means of said element and said cartridge being engageable with one another and structured to permit latching of said print element in only one rotational position upon engagement thereof during printing non-use.
In a print package including a rotatable print element and a cartridge for housing said print element, wherein the improvement comprises:
- (a) means included with said print element for orienting said print element;
- (b) means included with said cartridge, engageable and disengageable with said orientation means of said print element, for latching said print element in one rotational position against rotation upon engagement until unlatched for rotation upon disengagement.
A print package comprising in combination:
- (a) a rotatable print element including orientation means;
- and
- (b) a cartridge for housing said print element, said cartridge including orientation means, said orientation means of said element being structured for engagement and disengagement with said orientation means of said cartridge such that upon engagement, said element will be latched in one rotational position against rotation, and upon disengagement, said element will be unlatched for rotation.
