    Abstract: There is disclosed an envelope hopper for attachment to a printer requiring envelopes. Spring members provided with adjustable throats for permitting passage of a single envelope are biased downward against the upward force of the supply stack for compensating for changes in relative position of the uppermost envelope and the throats during separation from the stack.

    Abstract: A daisy wheel printer print element adapted to be housed and oriented in a cartridge during printing and storage. The element has a hammer impact side and a printing side and is made up of a circular central hub, petals connected to the hub and extending radially therefrom, and types carried on the outer extremities of the petals on the printing side of the element. The central hub is dish shaped with its protruding side on the impact side of the element. Carried on the protruding side of the central hub is an orientation protrusion having a stabilizing surface engulfing the axis of rotation of the element. The orientation protrusion is for cooperating with a matching opening in the cartridge. The stabilizing surface is for cooperating with a mating face on a selection motor drive hub. Within the orientation protrusion is a depression also engulfing the axis of rotation of the element. Located within the depression and radially displaced from the axis of rotation of the element is a drive opening. The drive opening is for accepting a drive pin carried by the drive hub. On the printing side of the element and centered within the dished side of the central hub is a bearing protrusion for acting against a bearing surface provided in the cartridge.

    Abstract: The purpose of the apparatus is to feed envelopes from a first hopper (40) to a print station (30) and then to deliver it to a second hopper (70) located over the first one, the print station being transversely oriented with respect to both hoppers. The uppermost envelope (44) in hopper (40) is first rotated 90 DEG by the combined action of a roller (50) and a pivot post (58); it is then conveyed to the print station (30) by a an endless belt (110) and back up rollers (120), where it is rotated 180 DEG ; then it is conveyed to the second hopper (70) by endless belt (110) and back up rollers (122); there it is again rotated 90 DEG by the combined action of a paddle wheel (74) and a notch (72) located in the side wall of the second hopper, and then is delivered to said second hopper with the appropriate orientation.

    Abstract: 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.
