Abstract
A printer includes an apparatus main body, an inner door unit, a main body gear, a transmission gear, and a lock mechanism section. The lock mechanism section locks the inner door unit against the apparatus main body and unlocks the inner door unit from the apparatus main body. The lock mechanism section includes a counter-engagement shaft which is long in a Y-direction, a lock lever having an engagement surface configured to engage with the counter-engagement shaft, and a tension spring that applies force to the lock lever to enable the engagement surface to change in position from a first posture to a second posture. In a closing operation, the engagement surface changes position to the second posture while shifting the position of contact with the counter-engagement shaft, and applies, to the counter-engagement shaft, a pull-in force for moving the inner door unit to a closed position.
