Abstract
In a forward/backward movement device, a forward/backward member moves so as to move forward or backward while rotating relative to the case; a restriction member is provided so as to be capable of moving between a restriction position for restricting the forward/backward member, and a release position for releasing the restriction, and restricts the forward/backward member by engaging a forward/backward member-side member in the restriction position; a drive unit is provided on the same side as is the forward/backward position control mechanism relative to the restriction member and the forward/backward member; and the drive shaft extends so as to include the direction in which the forward/backward member extends as a directional component.
Claims4
A forward/backward movement device, comprising:
- a case;
- a forward/backward member capable of moving forward and backward with respect to the case;
- a forward/backward position control mechanism that performs control such that the forward/backward member moves forward to a forward position where the forward/backward member moves forward with respect to the case and moves backward to a backward position where the forward/backward member moves backward with respect to the case;
- a restriction member that causes the forward/backward member to be in a restricted state in which the forward and backward movement is restricted;
- a drive section including a drive shaft and a main body that rotates the drive shaft;
- and
- a driving-force transmission member that is connected to one end of the drive shaft and transmits a driving force of the drive section to the restriction member to move the restriction member, wherein
- the forward/backward member is provided in the case so as to move forward and backward while rotating relatively with respect to the case,
- the forward/backward position control mechanism includes a case-side member which is provided in a predetermined position with respect to the case and a forward/backward-member-side member which is provided in the forward/backward member so as to fit to the forward/backward member such that the forward/backward-member-side member is rotatable relatively with respect to the forward/backward member,
- the restriction member is provided so as to be movable to a restricted position where the restriction member causes the forward/backward member to be in the restricted state and to a releasing position where the restricted state is released, the restriction member causing the forward/backward member to be in the restricted state by engaging with the forward/backward-member-side member in the restricted position,
- the drive section is provided on a side identical to a side where the forward/backward position control mechanism is provided with respect to the restriction member and the forward/backward member, and
- the drive shaft extends in a direction including, as a direction component, a direction in which the forward/backward member extends.
