PROBLEM TO BE SOLVED: To save an installation space and downsize a machine body. SOLUTION: In the operating switch unit, by the insertion of the swinging shaft 43 of a switch body 41 into the slot 43 of an operating support plate 70, the switch body 41 is supported by the operating supporting plate 70 in a manner that allows the right and left ends to freely swings on the swinging shaft 43 as a fulcrum and freely translate vertically. When a first stopping section 19 is operated, the switch body 41 rotates clockwise and the head 49 of a detection piece 47 shades a right sensor 77. When a second stopping section 20 is operated, the switch body 41 moves upward along a slot 45 with which the swinging shaft 43 engages, the shoulder portions 51 and 53 of the detection piece 47 shade left and right sensors 75 and 77, respectively. Furthermore, when a third stopping section 21 is operated, the switch body 41 rotates counterclockwise, the head 49 of the detection piece 47 shades the left sensor 75. COPYRIGHT: (C)2004,JPO
