PROBLEM TO BE SOLVED: To provide a sensor arrangement structure for a driving module by which the degree of freedom in the arrangement of an optical sensor is obtained and the sensor is easily and appropriately fixed in a sensor arranging part. SOLUTION: The sensor arrangement structure is equipped with a photointerrupter (optical sensor) 100 having a pair of element arranging parts 102 and 103 provided with a light emitting element or a photoelectric conversion element, and soldered on a flexible printed circuit board, and the sensor arranging part 90 of a module main body where the interrupter 100 is fixed. The arranging part 90 is equipped with a set wall 91 on which the interrupter 100 is placed, a fixed holding part 92 formed on either side of the wall 91, and an elastically deformed movable holding part 93 formed on the other side of the set wall 91 oppositely to the holding part 92 and holding the interrupter 100 placed on the set wall 91 between the fixed holding part 92 and the movable holding part 93 itself. The fixed holding part 92 has a 1st reference part 95 coming into contact with the front 100c of either element arranging part 102 and a 2nd reference part coming into contact with a 1st sensor outside surface 100a on either element arranging part 102 side. The movable holding part 93 comes into contact with a 2nd sensor outside surface 100b on the other element arranging part 103 side. COPYRIGHT: (C)2006,JPO&NCIPI |
