A printer is disclosed which determines whether or not an opening of the printer is open or closed. The printer includes an opening/closing mechanism for opening and closing the opening of the printer housing. The printer includes a controller configured to determine whether the opening is open or closed based on a light receiving state of a light receiving portion.

A movement transmission mechanism moves the first moveable body according to movement of a second moveable body.
