Cover opening/closing device and image forming apparatus including this

摘要

A cover opening/closing device includes an engage mechanism and a lock mechanism. The engage mechanism is provided in an apparatus body. The lock mechanism is provided in a cover. The lock member includes a button, a lock member, and an interlocking mechanism. The button is provided to be able to move linearly. The lock member is provided to be able to move linearly between a lock position and an unlock position. The interlocking mechanism interlocks a movement of the button with a movement of the lock member. The interlocking mechanism includes a return member, an oblique groove, and a projection part. The return member returns the button to an initial position. The projection part fits movably along the oblique groove. The oblique groove guides a relative movement of the projection part so as to interlock an operation of the button with a movement of the lock member.

主权项

1. A cover opening/closing device, comprising:
an engage mechanism provided at either one of an apparatus body and a turning cover centering a turning shaft with respect to the apparatus body; and a lock mechanism provided on either other one of the apparatus body and the cover; the lock mechanism including: a button provided to be able to move linearly in a normal line direction of an appearance surface of the either other one of the apparatus body and the cover; a lock housing holding the button; a lock member provided to be able to move linearly in a direction in parallel with the appearance surface between a lock position where the lock member is engaged with the engage mechanism and an unlock position where the lock member is disengaged; and an interlocking mechanism interlocking a movement of the button with a movement of the lock member; the lock member includes a through opening at a center part thereof, the interlocking mechanism including: a return member returning the button to an initial position; an oblique groove provided at either one of the button and the lock member and extending obliquely with respect to a normal line of the appearance surface; and a projection part provided in either other one of the button and the lock member and fitting movably inside the oblique groove; the return member penetrates through the through opening of the lock member and is disposed between the lock housing and the button, the oblique groove causing a relative movement of the projection part so as to interlock a pressing operation of the button located at the initial position with a movement of the lock member heading to the unlock position and causing a relative movement of the projection part so as to interlock a return operation of the button caused by the return member with a movement of the lock member heading to the lock position.
