## Abstract

The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on the side closer to the regulating guide in the sheet width direction Y, through which a sheet stopped on the conveying belt is taken out. A guide moving part moves the regulating guides. When a sheet is stopped on the conveying belt, the guide moving part moves the first and second regulating guides such that the regulating guide is retracted to a position at which a support surface does not support a first sheet end edge.

## Claims

### Claim 1

A sheet conveying apparatus comprising:
a receiving part for receiving a sheet conveyed in a predetermined conveying direction:
an endless conveying belt having a conveying surface extending in the predetermined conveying direction and configured to convey, in the predetermined conveying direction, the sheet that the receiving part receives;
a plurality of balls arranged in the predetermined conveying direction and configured to be rotatable in any direction while nipping the sheet with the conveying surface;
a first regulating guide disposed on a first side of the conveying belt in a sheet width direction crossing the conveying direction, having a first support surface for supporting a first sheet end edge on the first side of the sheet conveyed while being nipped by the conveying belt and the balls, and configured to move in the sheet width direction with the first sheet end edge supported by the first support surface to regulate the first sheet end edge;
a second regulating guide disposed on a second side of the conveying belt in the sheet width direction, having a second support surface for supporting a second sheet end edge on the second side of the sheet conveyed while being nipped by the conveying belt and the balls, and configured to move in the sheet width direction with the second sheet end edge supported by the second support surface to regulate the second sheet end edge;
a guide moving unit configured to move the first and second regulating guides in the sheet width direction; and
a take-out port provided on the first side of the conveying belt in the sheet width direction, through which a sheet stopped on the conveying belt can be taken out in a state where the first sheet end edge is located at a predetermined position, wherein
when a sheet is stopped on the conveying belt, the guide moving unit moves the first and second regulating guides such that the first support surface is located at a position at which it does not support the first sheet end edge in a state where the first sheet end edge is located at the predetermined position.

### Claim 2 (depends on 1)

The sheet conveying apparatus according to claim 1, wherein
when the first sheet end edge of the sheet stopped on the conveying belt is out of the predetermined position, the guide moving unit moves the first and second regulating guides so as to locate the first sheet end edge at the predetermined position.

### Claim 3 (depends on 1)

The sheet conveying apparatus according to claim 1, wherein
when the first sheet end edge of the sheet stopped on the conveying belt is located away from the predetermined position toward the first side, the guide moving unit moves the first and second regulating guides toward the second side and then moves the first regulating guide toward the first side such that the first support surface is located at a position at which it does not support the first sheet end edge.

### Claim 4 (depends on 1)

The sheet conveying apparatus according to claim 1, wherein
when the first sheet end edge of the sheet stopped on the conveying belt is away from the predetermined position toward the second side, the guide moving unit moves the first and second regulating guides toward the first side.
