PROBLEM TO BE SOLVED: To reliably open a tilt part up to a predetermined angle, without generating unnecessary noise, by driving a mounting part and the tilt part.SOLUTION: In an operation panel 12, a sector-shaped gear 63 that receives a driving force is provided coaxially with an opening and closing axis for a body. A discharged paper tray 13 is extended from the body, when in use, for a paper sheet to be placed thereon. A transmission mechanism 30 transmits the driving force for opening the operation panel 12 from a motor 41 to the operation panel 12, and also transmits the driving force for extending the discharged paper tray 13 from the body, from the motor 41 to the discharged paper tray 13. The transmission mechanism 30 is provided with a first planetary gear mechanism 62 that disengages from the sector-shaped gear 63 to cut off the driving force to be transmitted when the operation panel 12 is opened to the second angle smaller by a predetermined first angle than a full-open angle, in transmitting the driving force for opening the operation panel 12 from the motor 41 to the operation panel 12. |
