IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes an apparatus body, an outer cover, a conveyance unit, a movable roller, and an interlock mechanism. The outer cover is provided turnably between an outer closing position forming one surface of the apparatus body and an outer opening position in which the one surface of the apparatus body is set openable. The conveyance unit is provided turnably between an inner closing position in which an inside of the apparatus body is set closable and an inner opening position in which the inside of the apparatus body is set openable. The movable roller is pressed by a fixed roller pivotally supported inside of the apparatus body when the conveyance unit is displaced to the inner closing position. The interlock mechanism interlocks an operation of opening the outer cover with an operation of opening the conveyance unit.

1. An image forming apparatus, comprising:
an apparatus body; an outer cover provided turnably between an outer closing position forming one surface of the apparatus body and an outer opening position in which the one surface of the apparatus body is set openable; a conveyance unit disposed inside of the apparatus body more than the outer cover and provided turnably between an inner closing position in which an inside of the apparatus body is set closable and an inner opening position in which the inside of the apparatus body is set openable; a movable roller pivotally supported by the conveyance unit and being pressed by a fixed roller pivotally supported inside of the apparatus body when the conveyance unit is displaced to the inner closing position; and an interlock mechanism interlocking an operation of opening the outer cover with an operation of opening the conveyance unit; wherein the interlock mechanism comprises: an inner engaging part provided in the conveyance unit and is configured to be turnable between a lock position in which the inner engaging part is locked by an engaged part provided within the apparatus body and an unlock position in which the inner engaging part is unlocked from the engaged part; and an outer engaging part fixed to the outer cover and engaging with the inner engaging part locked by the engaged part when the outer cover is displaced to the outer closing position; the inner engaging part holds the conveyance unit at the inner closing position by resisting against a reaction force received by the movable roller by locking with the engaged part; the outer engaging part turns the inner engaging part from the lock position to the unlock position by relatively sliding with the inner engaging part in a process of turning the outer cover from the outer closing position to the outer opening position; and the outer engaging part is disengaged relatively from the inner engaging part after turning the conveyance unit from the inner closing position to the inner opening position by relatively sliding with the inner engaging part in a case of turning the outer cover further to the outer opening position after when the inner engaging part is displaced to the unlock position.
