In the first state, the inner wall has a predetermined angle with respect to a bottom surface of the recording target media cassette. In the second state, the inner wall has a steeper angle of inclination. In the first state, the inner wall separates the uppermost of the recording target media from a second recording target medium. In the second state, the inner wall contacts the leading edge of the recording target media loaded in the recording target media cassette and sets the leading edge of the recording target media at a uniform edge position.Type: ApplicationFiled: September 23, 2010Publication date: March 31, 2011Applicant: SEIKO EPSON CORPORATIONInventor: Kenji YANAGISHITA

Patent number: 7909319Abstract: To provide an image forming apparatus and image forming method that can prevent a decrease in image quality by preventing a step-out of a driving source, which occurs because a load of a feeding device is applied when a medium is transported for image formation. When no roller reset operation, by which a paper feed roller is returned to a reset position, is performed (YES in S21), it is judged whether a counted value N of a counter, which indicates a position of a sheet of paper, is below a threshold value Na, which indicates that it is in an A region in which a load of a hopper or paper return levers of an automatic sheet feeder (ASF) is applied to a stepping motor (S22). When N<Na, driving for high torque is selected (S23), and then paper transport in the A region is performed with a high torque (S25). On the other hand, when N?Na, driving for low torque is selected (S24) and then paper transport in a B region after the A region has passed is performed with a low torque (S25).Type: GrantFiled: August 17, 2007Date of Patent: March 22, 2011Assignee: Seiko Epson CorporationInventors: Yasutaka Shibagaki, Satoshi Noda

Publication number: 20100244361Abstract: A device (1) for example for a scan system, a deposit of documents, receipts, or similar flat objects (2) in a secured sequence in which the objects (2) are fed through a slot (9) of a rotary body (8) to a conveyer device (7) and are pushed therefrom to a stack of the receipts or objects, and the conveyer device (7) can be stopped when the rear edge of the receipt or object (2), seen in the direction of feed, is still arranged in the slot area of the rotary body (8). In this way, the rotation of the rotary body (8) can be triggered, causing the slot (9) to be rotated away from the end of the receipt (2), i.e. the end of the receipt slips out of the slot (9) or leaves it, however remains in the area of the rotary body (8), with an exterior of the body forming a hold-down unit for the end of the receipt while the next receipt (2) being fed. Any insertion of the next receipt under the previous receipt (2) is therefore prevented.Type: ApplicationFiled: March 29, 2010Publication date: September 30, 2010Applicant: ERNST REINER GMBH & CO.
