Publication number: 20180329350Abstract: A printer includes a printing unit which performs printing on a sheet and which discharges a printed sheet from a discharging opening, and a pair of body-side feet disposed on both sides in a width direction of a sheet to be discharged from the discharging opening. A sheet housing apparatus includes a housing unit which houses a sheet to be discharged from the discharging opening, and a pair of housing-side feet disposed on the both sides in the width direction. The sheet housing apparatus can be mounted from a predetermined mounting direction to the printer. The body-side feet and the housing-side feet are arranged to be disposed, in a state in which the sheet housing apparatus is mounted to the printer, so as to overlap with each other in the mounting direction and not to overlap with each other in the width direction.Type: ApplicationFiled: May 3, 2018Publication date: November 15, 2018Inventors: Toshiro Sugiyama, Yasuyuki Asai, Hiromasa Yoneyama, Tetsuo Kikuchi, Itaru Wada, Daiki Anayama
