Reciprocal movement device

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.
