<p>PURPOSE:To improve operability without discretely necessitating operations to attach and detach a paper feed tray and operations to turn on and off a power source switch by constituting the titled device in such a manner that the power source switch is turned on and off at the time of detaching and attaching the feed tray. CONSTITUTION:This device is provided with a device body 1, the power source switch 33 provided on the device body 1, and the paper feed tray 11 which is freely attachably and detachably mounted on the device body 1 and turns on and off the switch 33. To mount the tray 11, an operator once elastically deforms an arm 34 inward and positions the same in a support 31 of the body 1, then the tray 11 is mounted and the switch 33 is pressed to on by the arm 34. The pressing of the switch 33 by the arm 34 is released to turn off the switch 33 when the tray 11 is removed. Since the switch 33 is turned on and off by the attachment and detachment of the tray 11, the need for the discrete operations thereof is eliminated and the operability is improved.</p> |
