摘要:
A sheet material conveying apparatus is provided with retard levers for supporting a retard roller shaft, which are rotative centering on the central axis of rotation so as to press the retard roller to a conveying roller. Retard pressing springs are hooked to the spring latches of the retard levers, and the hooks of a slider. When the limiter gear of a torque limiter rotates, the tightening force exerted by a stepped spring against an inner race is caused to change, thus changing the rotating-load torque of the retard roller. A motor enables the limiter gear to rotate, while moving the slider up and down. In this way, it is made possible to change the rotating load torque of the retard roller, while changing the pressurized contact force of the retard roller against the conveying roller. With the structure thus arranged, it is attempted to make the life of rollers longer, and to prevent the occurrence of double feeding of sheet material.

A sheet feeding apparatus includes: a sheet feeding table on which sheets are stacked, the sheet feeding table being vertically movable; a sheet feeding roller mechanism provided in a vertical movement path of the sheet feeding table, the sheet feeding roller mechanism having a roller for feeding the sheets from the sheet feeding table one at a time, the roller being vertically displaceable; a spring for urging the sheet feeding roller mechanism in a direction of downward movement of the sheet feeding table; a detector for detecting when, during the upward movement of the sheet feeding table, the sheet feeding roller mechanism is lifted to a predetermined position against the spring, to stop the upward movement of the sheet feeding table; and a movable member movable and lockable for operating a change-over mechanism for changing the raised position of the sheet feeding roller mechanism which is obtained when the sheet feeding roller mechanism is detected by the detector.

A medium supply device includes a medium cassette that accommodates a medium, a dial that is rotatable around a predetermined rotation shaft, an angle-holding part to hold the dial, a subsidiary arm including arm parts that are independently displaceable, and a detection switch with switch parts that are pressed by arm parts of the subsidiary arm. The dial includes a display part on which display elements illustrating a medium size are arranged in a circumferential direction around the rotation shaft, a rotation lock part configured to be locked by the angle-holding part, and a projection formation part that includes projection parts configured to press the arm parts of the subsidiary arm in a circumferential direction around the rotation shaft. The projection parts selectively contact and displace the arm parts in accordance with the rotation angle of the dial to selectively press the switch parts of the detection switch.
摘要:
This invention overcomes the disadvantages of the prior art by providing a system and method for inserting contents into envelopes that generally reduces the number of operative device components, locates all components in a readily and accessible location, reduces the number of adjustments needed to change envelope size and contents size, provides an efficient and aesthetically pleasing design, allows for a highly flexible arrangement of backup hoppers to primary hoppers for feeding envelope contents and otherwise affords a substantial number of improvements over currently available envelope inserters. The illustrative embodiment includes a feed table with a low-slung swing arm for handling contents, a pivoting feed table that exposes the operative components on the underside, a novel raceway belt with projecting lugs for transporting contents to the insertion area, a primary and secondary contents hopper backup system, a mechanism for easily adjusting for different-sized envelopes, and a variety of other novel features.

An original-feeding device includes an original tray, a pickup roller configured to be lowered onto originals stacked on the tray and to feed one of the originals, the pickup roller configured to be lifted up after the feeding, a conveyor configured to convey the fed original, a length detector configured to detect a length of the conveyed original, an original sensor configured to detect a trailing edge of the conveyed original, and a controller configured to control the pickup roller either in a first mode in which the pickup roller is lowered in accordance with a detected length of the original or in a second mode in which the pickup roller is lowered at the detection of a trailing edge of the original. The controller changes the first mode to the second mode if lengths of the originals detected by the length detector vary.

A recording apparatus such as a laser beam printer has a laser beam unit for forming an image, a cassette for automatically feeding paper sheets, a manual insertion port for allowing manual insertion of paper sheets, a switch to allow selection of the cassette sheet feed or manual insertion sheet feed at the side of the printer, a timer to count a predetermined period of time, and a CPU for switching from the manual insertion sheet feed mode to the cassette sheet feed mode when no paper sheet is manually inserted in the manual insertion sheet feed mode after the time in the timer has elapsed. Undesired accumulation of data designating printing in the cassette sheet feed mode is prevented.
