MEMBER MOVING MECHANISM AND IMAGE FORMING APPARATUS INCLUDING SAME

摘要

A member moving mechanism includes a moving member movable in first positive and negative directions, a moved member that moves in second positive and negative directions when the moving member moves, a belt member connecting the moving member to the moved member, a belt-member guide member, an openable-closable cover engaged with the moving member, a first biasing member that biases the moved member in the second negative direction, and a second biasing member that biases the moving member in the first positive direction with a biasing force larger than that of the first biasing member. The moving member moves in the first positive direction with the biasing force of the second biasing member when the openable-closable cover moves in an opening direction, while the moving member moves in the first negative direction against the biasing force of the second biasing member when the openable-closable cover moves in a closing direction.

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; a first biasing member that biases the moved member in the second negative direction; and a second biasing member that has a biasing force larger than a biasing force of the first biasing member, and that biases the moving member in the first positive direction, the moving member being caused to move in the first positive direction by the biasing force of the second biasing member when the openable-closable cover rotates in an opening direction, the moving member moving in the first negative direction against the biasing force of the second biasing member when the openable-closable cover rotates in a closing direction.
