Image forming apapratus
First Claim
1. An image forming apparatus comprising:
- a movable member including an operating unit for operating the image forming apparatus, and a rotation shaft; and
a holding unit configured to hold the movable member,wherein the movable member is capable of moving between a first position and a second position by using the rotation shaft to rotate with respect to the holding unit, and the movable member is held in a predetermined position when one of the movable member and the holding unit is pressed, in a longitudinal direction of the rotation shaft, against the other of the movable member and the holding unit,wherein a direction in which the operating unit is pressed in order to operate the image forming apparatus is a direction in which the movable member is pressed when a position of the movable member is changed from the first position to the second position, andwherein the holding unit holds the movable member so that a requisite force for changing the position of the movable member from the first position to the second position is larger than a requisite force for changing the position of the movable member from the second position to the first position.

Abstract
An image forming apparatus includes a movable member equipped with an operating unit for operating the image forming apparatus, wherein the movable member can be a first state and a second state by changing its position with respect to an main body of the apparatus, and a holding unit configured to hold the movable member, wherein the direction in which the operating unit is depressed in order to operate the image forming apparatus is the direction in which the movable member is depressed when the position of the movable member is changed from the first state to the second state, and wherein the holding unit holds the movable member so that the requisite force for changing the movable member from the first state to the second state is larger than the requisite force for changing the movable member from the second state to the first state.

9. An image forming apparatus comprising:
-
a movable member including an operating unit for operating the image forming apparatus, and a rotation shaft; and a holding unit configured to hold the movable member, wherein the movable member is capable of moving between a first position and a second position by using the rotation shaft to rotate with respect to the holding unit, and the movable member is held in a predetermined position when one of the movable member and the holding unit is pressed, in a longitudinal direction of the rotation shaft, against the other of the movable member and the holding unit, wherein one of the movable member and the holding unit is provided with a plurality of recesses arranged side by side, and the other of the movable member and the holding unit is provided with a protrusion capable of fit-engagement with each of the plurality of recesses, wherein each of the plurality of recesses has regulating surfaces configured to regulate releasing of the fit-engagement of the protrusion and the recess and to hold the protrusion, wherein the movable member is maintained in the predetermined position in a state in which the protrusion is fit-engaged with the recess, and the movable member moves from the state in which the protrusion is fit-engaged with the recess, with the protrusion moving with respect to the recess, whereby the protrusion climbs over a regulating surface to release the fit-engagement with the recess to become capable of fit-engagement with another of the plurality of recesses, wherein a direction in which the operating unit is pressed in order to operate the image forming apparatus is a direction in which the movable member is pressed when a position of the movable member is changed from the first position to the second position, and wherein, assuming that, of the regulating surfaces, the regulating surface the protrusion climbs over when the movable member is placed in the second position from the first position is a first regulating surface, that the regulating surface the protrusion climbs over when the movable member is placed in the first position from the second position is a second regulating surface, and that the angles of the first regulating surface and the second regulating surface with respect to the moving direction of the protrusion with respect to the recess are α and
β
, respectively (α
, β
≦
90°
), the angles α and
β
satisfy α
>
β
, so that it can be more difficult for the protrusion to climb over the first regulating surface than to climb over the second regulating surface. - View Dependent Claims (10, 11)

12. An image forming apparatus comprising:
-
a movable member including an operating unit for operating the image forming apparatus, and a rotation shaft; and a holding unit configured to hold the movable member, wherein the movable member is capable of moving, with respect to the holding unit, to a first direction and a second direction opposite to the first direction, and the movable member is held in a predetermined position when one of the movable member and the holding unit is pressed, in a longitudinal direction of the rotation shaft, against the other of the movable member and the holding unit, wherein the operating unit is pressed in the first direction in order to operate the image forming apparatus, and wherein in a case where the movable member placed in the predetermined position is moved with respect to the holding unit, a resistance force received by the movable member from the holding unit to prevent the movable member from being moved with respect to the holding unit is larger when the movable member is moved from the predetermined position to the first direction than when the movable member is moved from the predetermined position to the second direction. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. An image forming apparatus comprising:
-
a movable member comprising a rotation shaft; and a holding unit configured to hold the movable member, wherein the movable member is capable of moving between a first position and a second position by using the rotation shaft to rotate with respect to the holding unit, and the movable member is held in a predetermined position when one of the movable member and the holding unit is pressed, in a longitudinal direction of the rotation shaft, against the other of the movable member and the holding unit, and wherein the holding unit holds the movable member such that a requisite force for changing the position of the movable member from the first position to the second position is larger than a requisite force for changing the position of the movable member from the second position to the first position. - View Dependent Claims (20, 21, 22, 23, 24)
