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.

First claim

The invention claimed is:

1. 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,
the drive shaft extends in a direction including, as a direction component, a direction in which the forward/backward member extends,
the forward/backward position control mechanism includes a plate-shaped guiding section and a guided section, the plate-shaped guiding section being configured to regulate a relative movement operation of the case-side member and the forward/backward-member-side member, the guided section being a section to be guided by the plate-shaped guiding section,
the forward/backward member is moved to the forward position and the backward position when the guided section is guided to a first position and a second position in the plate-shaped guiding section, and
any one of the case-side member and the forward/backward-member-side member includes the guided section, and the other one of the case-side member and the forward/backward-member-side member includes the plate-shaped guiding section.

2. The forward/backward movement device according to claim 1 , wherein any one of the case and the forward/backward member includes a trajectory guiding section that guides a movement trajectory of the forward/backward member such that the forward/backward member moves forward and backward while rotating relatively with respect to the case, and the other one of the case and the forward/backward movement member includes a trajectory guided section that is guided by the trajectory guiding section.

3. The forward/backward movement device according to claim 1 , further comprising a control cable that has one end linked to the restriction member and is led to an outside of the case,
wherein the restriction member is moved from the restricted position to the releasing position by operating the control cable, and the restricted state is thus released.
