Reciprocal movement device
A forward/backward movement device includes: a case; a forward/backward member; a biasing member that biases the forward/backward member; a moving member that is housed in the case and moves between a first position where the forward/backward member is capable of moving forward by a biasing force generated by the biasing member and a second position where the forward movement of the forward/backward member is stopped; and a restricting member that restricts a movement of the moving member by moving to a position for restricting the moving member while a lid is open, in which the restricting member restricts a movement of the moving member from the first position to the second position in a case where the forward/backward member moves backward while the lid is open.
1 . A forward/backward movement device in combination with a lid, the forward/backward movement device comprising:
a case;
a forward/backward member that moves forward in a direction from an inside of the case to an outside thereof, or moves backward in a direction opposite to the direction, the forward/backward member including one end housed in the case and another end protruding from the case;
a biasing member that biases the forward/backward member;
a moving member that is housed in the case and moves between a first position, in which the forward/backward member is capable of moving forward by a biasing force generated by the biasing member, and a second position, in which the forward movement of the forward/backward member is stopped; and
a first restricting member that restricts a movement of the moving member by moving to a position for restricting the moving member while the lid is open, wherein the first restricting member restricts a movement of the moving member from the first position to the second position when the forward/backward member is forced to move backward while the lid is open;
a forward/backward-member-side member that moves forward and backward together with the forward/backward member within the case while rotatably holding the forward/backward member; and
a pushing force transmission member that transmits a pushing force generated when the lid is closed, wherein
the moving member is restricted by the first restricting member from the moving from the first position to the second position and is not engaged with the forward/backward-member-side member so as to allow a forward movement of the forward/backward member when the pushing force transmission member moves forward and the forward/backward-member-side member is forced to move backward while the lid is open.
2 . The forward/backward movement device according to claim 1 , further comprising a rotational force transmission member that transmits a rotational force by a motor or manual operation to move the moving member by the rotational force, wherein
the first restricting member restricts a movement of the rotational force transmission member when the forward/backward member is forced to move backward while the lid is open.
3 . The forward/backward movement device according to claim 2 , wherein
the first restricting member restricts the movement of the rotational force transmission member by being locked to the rotational force transmission member.
4 . The forward/backward movement device according to claim 2 , wherein
the rotational force transmission member is a gear, and
the first restricting member stops rotation of the gear when the forward/backward member is forced to move backward while the lid is open.
5 . The forward/backward movement device according to claim 4 , wherein
the gear is D-cut processed, and
the first restricting member stops the rotation of the gear by being in contact with a D-cut surface when the forward/backward member is forced to move backward while the lid is open, and allows the rotation of the gear by being away from the D-cut surface when the forward/backward member moves backward while the lid is closed.
6 . The forward/backward movement device according to claim 1 , wherein
the first restricting member moves together with a pushing force transmission member that transmits a pushing force generated when the lid is closed, and enables the movement of the moving member when the pushing transmission member is pushed in an inside of the case as a result of the lid being closed.
7 . The forward/backward movement device in combination with the lid according to claim 1 , wherein
the forward/backward member is pushed toward the outside of the case by the biasing force of the biasing member and the moving member is not engaged with each of the first restricting member and the forward/backward-member-side member so as to allow a forward movement of the forward/backward-member-side member, when the pushing force transmission member and the forward/backward-member-side member each are forced to move backward while the lid is open and the pushing force transmission member is pushed in.
8 . The forward/backward movement device in combination with the lid according to claim 1 , wherein
the forward/backward-member-side member comprises:
a second restricting member that restricts a forward position of the forward/backward member; and
an engaged member that engages with an engaging member provided in a restricting portion that moves together with the pushing force transmission member.
9 . The forward/backward movement device in combination with the lid according to claim 1 , wherein
the first restricting member moves together with the pushing force transmission member when the lid is closed, and enables the movement of the moving member when the pushing transmission member is pushed in an inside of the case as a result of the lid being closed.
