Abstract: In a recording apparatus for stably conveying a recording medium to a recording portion by a convey belt, the recording medium (not shown) is passed through a nip of a pair of separation supply rollers 204, 205-1 and enters into a nip between a convey belt 301 and a driven roller 302-1. Thereafter, the recording medium is conveyed by the convey belt 301 while being held down by spur wheels 303 to 307 and is passed through a recording portion including various color recording heads 400B, 400C, 400M and 400Y. When a tip end of the recording medium is detected by a recording medium detect sensor 314, the supply roller 205-1 is disengaged from the separation roller 204, so that the convey belt 301 is not subjected to the influence of the pair of separation supply rollers 204, 205-1 via the recording medium. Further, when a trail end of the recording medium is detected by a recording medium detect sensor 216, the driven roller 302-1 is disengaged from the convey belt 301, so that the recording medium is not subjected to conveyance resistance from the driven roller 302-1.

Abstract: PROBLEM TO BE SOLVED: To solve such a problem with a method for piercing a needle-like member in an uppermost stacked sheet which is one of sheet separating methods that when the sheet is delivered to a sheet feeding means positioned on a downstream side, the sheet is not smoothly disengaged from a needle part, and a needle tip hooking scratch is given to the surface of the sheet or a defective sheet feed occurs. SOLUTION: A retractable roller is installed at the inlet of a feeding part. When the sheet arrives at the roller, the roller holds the sheet and, after the sheet is passed through the roll, the roller waits for a next sheet. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To solve problems that since a carrying belt and a driven roller are separated from each other only by the amount of maximum sheet thickness enabling sheet carrying, if a torn sheet piece remains within the sheet carrying, it is difficult for a user to see the torn sheet piece and the hidden sheet piece makes it difficult to perform normal processing to remove paper jam, and that even when the presence of the torn sheet piece is confirmed, it is extremely difficult for the user to remove the torn sheet piece; and thus to provide an image forming device enabling the user to securely perform the processing to remove paper jam without increasing the overall size of a sheet carrying device. SOLUTION: In this sheet carrying device, after a pressurization release mechanism of a sheet carrying mechanism is performed in conjunction with movement of a slide pressurization auxiliary means, a sheet carrying unit is rotated and retreated. Thus, without enlarging an opening of the sheet carrying unit, a sufficient space for performing the processing to remove paper jam can be secured, and the simplified and inexpensive device can be provided.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that, in a sheet conveyor held by a conveying belt driven by a conveying roller and a driven roller attachable/detachable to/from the belt, the entire driven roller unit is moved in the separating direction from the conveying belt during paper jamming, jammed paper is removed; however, since the entire driven roller unit is moved, the conveyor becomes complicated, the cost is increased, a space for the entire unit to move is required, and an increase in size and a place of installation of the conveyor are limited.
SOLUTION: A sheet conveying means has a pressurizing means to abut a driven conveying means at a predetermined abutting force, and a movable slide pressurizing auxiliary means which can be switched to a pressurizing state and a depressurizing state is provided on a sheet conveyor to hold and convey a sheet. In addition, the pressurizing auxiliary means is reciprocated in the direction substantially parallel to the sheet conveying direction, and has a turnable rotary member, and is switched to a pressurizing state and a depressurizing state.
