COVER OPENING/CLOSING DEVICE AND IMAGE FORMATION DEVICE PROVIDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cover opening/closing device and the like for miniaturization.SOLUTION: A cover opening/closing device 7 is provided with: an engaging mechanisms 20 provided in a device main body 2; and a lock mechanism 30 provided in a cover 6. The lock mechanism 30 is provided with: a button 32 that moves in a normal line direction of an appearance surface 11 of the cover 6; a locking member 33 that moves parallel to the appearance surface 11; and an interlock mechanism 34 that interlocks the movement of the button 32 and the locking member 33 with each other. The interlock mechanism 34 includes: a return spring 60 that returns the button 32 to an initial position P1; a skew groove 61 inclining relative to a normal line V of the appearance surface 11; and a projection part 62 that fits in the skew groove 61. The skew groove 61 guides relative displacement of the projection part 62 such that push-in operation of the button 32 and movement of the locking member 33 toward an unlock position L2 are interlocked with each other, and also guides the relative displacement of the projection part 62 such that return operation of the button 32 and movement of the locking member 33 toward a lock position L1 are interlocked with each other.SELECTED DRAWING: Figure 4
