PROBLEM TO BE SOLVED: To provide a tray locking mechanism which is not fixed for use in either a right side or a left side. SOLUTION: A plane of a locking member 61 for a tray is formed in a linear shape parallel to the direction of transfer of the tray, and the locking members 61 are paired and arranged symmetrically on the back and this sides of an under surface of the tray. A locking device 62 is composed of a lock member for locking the tray, a supporting member for swingably supporting the lock member, and a guide member which is pressed by the locking member 61 so as to tilt and guide the lock member. An unlocking device is composed of a shove-on member, which shoves toward the guide member of the locking device 62, and a drive mechanism for the shove-on member. |
