Abstract:
1. A recording medium accumulating device comprising: a cylindroid roller for winding up the recording medium and endless belts; wherein, the cylindroid roller includes a roller and a peripheral belt supported by the roller; the endless belts include a first belt, a second belt, and a third belt; a first passage, a second passage, and a third passage are respectively formed at positions where the first belt, the second belt, and the third belt contact with the peripheral surfaces of the cylindroid roller, and the first, second, and third passages together form a closed medium-feeding passage; a medium-discharging passage is formed between the first belt and the second belt; a medium-withdrawing passage is formed between the second belt and the third belt; a medium-entering passage is formed between the first belt and the third belt; the medium-entering passage, the medium-withdrawing passage and the medium-discharging passage are connected with the medium-feeding passage; and the medium-feeding passage is configured to drive the recording medium to rotate with the cylindroid roller using the friction force of the contacting surfaces, so as to accumulate the recording medium.
