PROBLEM TO BE SOLVED: To provide an image formation apparatus lock mechanism capable of suppressing dropping of an image formation apparatus from a placement part.SOLUTION: A printer lock unit 1 includes a tray storage part 3, and a printer 2 placed on the tray storage part 3. The printer 2 includes a regulation projection 29 and an oscillation part 30 arranged with an interval in the cross direction. The tray storage part 3 includes a lock member 38 sliding in the cross direction and a coil spring 40 energizing the lock member 38. The lock member 38 includes a regulation part 43, a contact surface 42A brought into contact with the oscillation part 30, and an inclined surface 42B inclined upward toward the front side continuously from the contact surface 42A. The coil spring 40 energizes the lock member 38 backward so that the regulation part 43 is separated from the regulation projection 29. The regulation part 43 is arranged within a rotation trajectory T of the regulation projection 29 with the rotation fulcrum of the printer 2 as the center when the printer 2 is rotated.SELECTED DRAWING: Figure 3 |
