Abstract
A sheet conveyer to shift a sheet at one side of the sheet conveyer in a widthwise direction is provided. The sheet conveyer includes a pair of rollers, a regulative guide arranged at a position closer to the one side than the pair of rollers in the widthwise direction, a first guide arranged at a position upstream from the pair of rollers with regard to a conveying direction to contact a first area on a first face of the sheet at a position closer to the one side in the widthwise direction than a widthwise center of the sheet, and a second guide arranged at a position upstream from the pair of rollers with regard to the conveying direction to contact a second area on a second face of the sheet. The second guide partly overlaps the first guide in a direction of height.
Claims8
A sheet conveyer configured to shift a sheet being conveyed in a conveying direction sideward at one side of the sheet conveyer in a widthwise direction, the widthwise direction being orthogonal to the conveying direction, the sheet conveyer comprising:
- a pair of rollers configured to nip the sheet and apply a conveying force to shift the sheet sideward to the sheet;
- a regulative guide arranged at a position closer to the one side than the pair of rollers in the widthwise direction, the regulative guide extending in the conveying direction and being configured to contact an edge of the sheet closer to the one side in the widthwise direction to regulate a position of the edge;
- a first guide arranged at a position upstream from the pair of rollers with regard to the conveying direction, the first guide being configured to contact a first area on a first face of the sheet at a position closer to the one side in the widthwise direction than a widthwise center of the sheet;
- and
- a second guide arranged at a position upstream from the pair of rollers with regard to the conveying direction, the second guide being configured to contact a second area on a second face of the sheet at a position closer to the one side in the widthwise direction than the widthwise center of the sheet, the second area being different from the first area in the widthwise direction, the second guide being arranged to partly overlap the first guide in a direction of height when viewed in the widthwise direction, the direction of height being orthogonal to the conveying direction and the widthwise direction.
An image forming apparatus, comprising:
- an image forming unit configured to form an image on a sheet being conveyed;
- and
- a sheet conveyer configured to convey the sheet in a conveying direction and shift the sheet being conveyed sideward at one side of the sheet conveyer in a widthwise direction, the widthwise direction being orthogonal to the conveying direction, the sheet conveyer comprising:
- a pair of rollers configured to nip the sheet and apply a conveying force to shift the sheet sideward to the sheet;
- a regulative guide arranged at a position closer to the one side than the pair of rollers in the widthwise direction, the regulative guide extending in the conveying direction and being configured to contact an edge of the sheet closer to the one side in the widthwise direction to regulate a position of the edge;
- a first guide arranged at a position upstream from the pair of rollers with regard to the conveying direction, the first guide being configured to contact a first area on a first face of the sheet at a position closer to the one side in the widthwise direction than a widthwise center of the sheet;
- and
- a second guide arranged at a position upstream from the pair of rollers with regard to the conveying direction, the second guide being configured to contact a second area on a second face of the sheet at a position closer to the one side in the widthwise direction than the widthwise center of the sheet, the second area being different from the first area in the widthwise direction, the second guide being arranged to partly overlap the first guide in a direction of height when viewed in the widthwise direction, the direction of height being orthogonal to the conveying direction and the widthwise direction.
