PROBLEM TO BE SOLVED: To provide a drive mechanism which operates an operator at low costs or in small size.SOLUTION: A drive mechanism 49 operates an operator 34. The drive mechanism 49 has a motor 43; a drive board 43b driving the motor 43; a driving shaft 41 which rotates by driving of the motor 43 and operates the operator 34; and a sensor 46 detecting a rotation position of the driving shaft 41. The sensor 46 has a detection body 46a provided for the drive board 43b. The driving shaft 41 is provided with a detected body 46b detected by the detection body 46a. The driving shaft 41 goes through the drive board 43b or goes across the vicinity of an edge of the drive board 43b.SELECTED DRAWING: Figure 10 |
