SHEET SUPPLY DEVICE AND MEDIUM PROCESSING DEVICE

摘要

A sheet supply device that is addable to a medium processing device includes a strage part storing a medium and a controller. The controller performs a first operation in which the medium is supplied from the storage part of the sheet supply device, and a second operation in which another medium supplied from an upstream side of a medium path is carried to a downstream side. When the second operation is performed, the controller operates the carrying part by transmitting a drive force to the carrying part via the transmission mechanism without operating the carrying transmission member.
