Abstract

An image processing apparatus includes an apparatus body, a feeding cassette, a pin member, a lever, an elastic member, and a guide mechanism. The feeding cassette is insertable into and ejectable from the apparatus body in one direction and includes an insertion position for insertion into the apparatus body and an ejection position for ejection from the apparatus body. The pin member is connected to the feeding cassette. The lever is rotatable around an axis in a first direction, and includes a pin engagement portion engaging with the pin member at a tip end in the axial direction. The elastic member includes a tip end connected between the rotation axis of the lever and the pin engagement portion of the lever, and adds a force for rotation in an insertion direction. The guide mechanism shortens a distance between the pin member and the rotation axis of the lever.

First claim

1 .- 10 . (canceled)

11 . A mechanism for easing transition of a cassette to and from an insertion position and an ejection position from an apparatus body, the mechanism comprising:
a pin member configured to connect to the cassette in a first direction orthogonal to a longitudinal direction along which the cassette is configured to be inserted or ejected; a lever configured to rotate about a rotational axis in the first direction, the lever comprising a first contact surface; an elastic member coupled to the lever and configured to exert a rotational force on the lever to bring the pin member into contact with the first contact surface of the lever, the pin member being spaced from the rotational axis of the lever; a pin engagement portion disposed at a tip end of the lever; and a guide hole configured to receive the pin member, the pin member being permitted to travel along an edge of the guide hole in a second direction orthogonal to the first direction and the longitudinal direction during a transition between insertion and ejection, the guide hole being configured such that a distance between the pin member and the rotational axis of the lever when the transition is ejection to insertion is different than a distance between the pin member and the rotational axis when the transition is from insertion to ejection.

12 . The mechanism according to claim 11 , further comprising an auxiliary lever configured to rotate about a rotational axis of the auxiliary lever in the first direction, and configured such that a base end of the elastic member is connected to a tip end of the auxiliary lever.

13 . The mechanism according to claim 12 , further comprising an auxiliary elastic member configured such that a tip end of the auxiliary elastic member is connected to a base end of the auxiliary lever.

14 . The mechanism according to claim 11 , wherein a dimension of the guide hole in the second direction is not constant.

15 . The mechanism according to claim 14 , wherein the dimension of the guide hole in the second direction increases in the longitudinal direction, which is an insertion direction of the cassette.
