PURPOSE: To reduce labor and cost for assembling a receiving unit by holding a receiving sensor between a wall with a receiving port faced to a receiving port in a sensor mounting part and a sensor hooking pawl. CONSTITUTION: When a receiving sensor 44 is mounted into a unit cover 43 for a receiving unit 34, the receiving sensor 44 is pressed into a sensor mounting part 47 with a sensor body 44b ahead. At the same time when a sensor substrate 44a for the inserted receiving sensor 44 is hooked across a sensor locking pawl 47c, the sensor body 44b is put in contact with the inner face of the lower wall 47a of the sensor mounting part 47. The receiving sensor 44 is held between the lower wall 47a and the sensor locking pawl 47c in the state that the sensor body 44b is faced to a receiving port 47b and exposed to the receiving port 47b, and mounted onto the unit cover 43 without using fixing parts such as screws. |
