It is preferable. For example, it may be configured to include a stepping motor that rotates by inputting a pulse signal, and position control may be performed accurately with an inexpensive and simple configuration.
- the back part 2b of the casing 2 is elongated to the back side, and the entire casing 2 is L-shaped because the space for storing the turret rotation driving unit 23 and the turret longitudinal driving unit 24 is stored. This is for securing the back surface 2b.
