Operation unit and image forming apparatus
An operation unit for image forming apparatus is disclosed. The operation unit includes: a bearing portion configured to rotatably support a shaft portion; a restricting portion provided at a position different from that of the bearing portion in an axial direction of the shaft portion, a restricting portion being configured such that when a supporting portion is rotated in a first direction from a first angle toward a second angle, the restricting portion restricts a rotation of the supporting portion in the first direction by abutting a mounting portion at a position where the operation unit forms the second angle; and an abutting portion provided on an opposite side of the restricting portion via the bearing portion in the axial direction, the abutting portion being configured to abut on the shaft portion.
1 . An image forming apparatus comprising:
a first casing including a top surface;
an operation unit including:
a second casing, which is movably placed on the top surface and receives operations by the user, separate from the first casing;
a supporting portion that pivots in a predetermined direction around a rotation shaft and supports the second casing in a first state where the angle between the top surface and the second casing is a first angle and in a second state where the angle between the top surface and the second casing is a second angle; and
a restricting portion that contacts the supporting portion and restricts rotation of the supporting portion in the predetermined direction while the supporting portion is in the second state,
wherein an end portion of the rotating shaft in the direction of an axis of the rotation shaft is elastically deformable in the direction of the axis of rotation shaft, and
wherein in a state where the end portion of the rotation shaft is elastically deformed in the direction of the axis of rotation shaft, the contact between the supporting portion and the restricting portion is released, and the restriction of rotation of the supporting portion in the predetermined direction is released.
2 . The image forming apparatus according to claim 1 , wherein the operation unit is connected to the first casing by a cable.
3 . The image forming apparatus according to claim 1 , wherein the end portion of the rotation shaft is elastically deformable in the direction from an end of the rotation shaft toward a center in the direction of the axis of rotation shaft.
4 . The image forming apparatus according to claim 1 , wherein:
both ends of the rotation shaft in the direction of the axis of rotation shaft are elastically deformable in the direction of the axis of rotation shaft,
in a state where both ends of said rotary shaft are elastically deformed in the direction of the axis of rotation shaft, the contact between the supporting portion and the restricting portion is released, and the regulation of the rotation of the supporting portion in the predetermined direction is released.
5 . The image forming apparatus according to claim 1 , wherein:
the second state is where the supporting portion is rotated in the predetermined direction from the first state,
in a state where the end of the rotation shaft is elastically deformed in the direction of the axis of rotation shaft and the contact between the supporting portion and the restricting portion is released, the supporting portion is in a third state where the supporting portion is further rotated in the predetermined direction from the second state.
6 . The image forming apparatus according to claim 1 , wherein while the supporting portion in the first state, the supporting portion is not in contact with the restricting portion.
7 . The image forming apparatus according to claim 1 , wherein:
the operating portion further includes a display portion that displays an image,
while the supporting portion is in the first state, the display portion and the top surface are at a third angle, and
while the supporting portion is in the second state, the display portion and the top surface are at a fourth angle.
