a motor; and
a second moving mechanism configured to move the striking mechanism in the second direction against a force of the first moving mechanism,
wherein the striking mechanism includes:
a main body portion extending in the first direction; and
first engaging portions disposed on the main body portion, and spaced apart from each other in the first direction,
wherein the second moving mechanism includes:
a rotational element rotated by the motor, the rotational element including a drive shaft extending in a third direction crossing the first and second directions, and a first support and a second support spaced apart from each other in the third direction; and
second engaging portions disposed between the first support and the second support and spaced apart from each other in a rotation direction of the rotational element, the second engaging portions being engaged with and released from the first engaging portions, respectively, each second engaging portion having a pin shape,
wherein the first engaging portions protruding from the main body portion in a direction intersecting with the first and second directions,
wherein the first engaging portions include a first-first engaging portion having a first protrusion amount from a center line of the main body portion and a second-first engaging portion having a second protruding amount from the center line of the main body portion, the second protruding amount being greater than the first protrusion amount, the center line of the main body portion being parallel with the first direction, and
wherein the first-first engaging portion and the second-first engaging portion are arranged in that order in the first direction.
