Member moving mechanism and image forming apparatus including same

摘要

A member moving mechanism includes a moving member, a moved member, a belt member, an openable-closable cover that is rotatable about a rotation shaft with the openable-closable cover engaged with the moving member, and a first biasing member. The moving member moves in a first negative direction with a biasing force of the first biasing member when the openable-closable cover rotates in an opening direction, while the moving member moves in a first positive direction against the biasing force of the first biasing member when the openable-closable cover rotates in a closing direction. The moving member has a boss formed to abut a first-positive-direction side of the engaging piece projecting from the rotation shaft. A biasing force in the opening direction is applied to the openable-closable cover by the boss pressing the engaging piece in the first negative direction with the biasing force of the first biasing member.

主权项

1. A member moving mechanism, comprising:
a moving member that is movable in a first positive direction and a first negative direction that is opposite to the first positive direction; a moved member that moves in a second positive direction that is different from both the first positive direction and the first negative direction in conjunction with movement of the moving member in the first positive direction, and that moves in a second negative direction that is opposite to the second positive direction in conjunction with movement of the moving member in the first negative direction; a belt member that connects the moving member to the moved member; a belt-member guide member that regulates a moving direction of the belt member; an openable-closable cover that is rotatable about a rotation shaft in a state where the openable-closable cover is engaged with the moving member; and a first biasing member that biases the moved member in the second negative direction, the moving member being caused to move in the first negative direction by the biasing force of the first biasing member when the openable-closable cover rotates in an opening direction, the moving member moving in the first positive direction against the biasing force of the first biasing member when the openable-closable cover rotates in a closing direction, the openable-closable cover having an engaging piece projecting from the rotation shaft, the moving member having a boss abutting the engaging piece on a first-positive-direction side of the engaging piece, the boss applying a biasing force to the openable-closable cover in the opening direction by pressing the engaging piece in the first negative direction with the biasing force of the first biasing member.
