Conveyor system and image forming apparatus including same

摘要

A conveyor system includes a first conveyor belt entrained about a separation roller and a support roller disposed upstream from the separation roller, a second conveyor belt entrained about a first roller disposed at an uppermost stream in a transport direction of a sheet-type medium and a second roller disposed downstream therefrom, a belt alignment device to tilt a rotary shaft of the separation roller to restrict a range of belt mistracking of the first conveyor belt in a width direction thereof within a predetermined range, and a restriction member to restrict an amount of inclination of the rotary shaft such that a hypothetical extended plane, which is a hypothetical extension of the outer circumferential surface of the first conveyor belt between the separation roller and the support roller to a downstream side in the transport direction, does not contact a rotational center axis of the first roller.

主权项

1. A image forming apparatus, comprising:
a transfer belt formed into an endless loop, entrained about and stretched taut between a plurality of rollers including a separation roller including a rotary shaft and a support roller disposed upstream from the separation roller in a traveling direction of the transfer belt, to carry a sheet-type medium on an outer circumferential surface of the transfer belt; a conveyor belt formed into an endless loop, entrained about and stretched taut between a plurality of rollers including a first roller disposed at an uppermost stream in a transport direction of the sheet-type medium and a second roller disposed downstream from the first roller, to carry, on an outer circumferential surface of the conveyor belt, the sheet-type medium separated from a wound portion of the transfer belt wound around the separation roller; a belt alignment device to tilt the rotary shaft of the separation roller to restrict a range of belt mistracking of the transfer belt in a width direction of the transfer belt within a predetermined range; and a restriction member to restrict an amount of inclination of the rotary shaft of the separation roller such that a hypothetical extended plane, which is a hypothetical extension of the outer circumferential surface of the transfer belt between the separation roller and the support roller to a downstream side in the transport direction, does not contact a rotational center axis of the first roller.
