PURPOSE:To prevent a device from defective operation caused by the drop of parts by constituting a mobile frame fixing means of a handle part and an elastic member such as soft urethane foam resin fixed on a locking member at its one end. CONSTITUTION:The front sides of 1st and 2nd frame bodies 11, 12 are formed as free ends and can be optionally moved on a guide plate 32 by sliding members 33, 34 and their depth sides are freely slidably supported by a guide rod 35. The mobile frame fixing means 14 is constituted so as to be driven on the front sides of both the frame bodies 11, 12. Thus, the locking member 25 is moved along guide rails 26, 27 against the tensile force of a spring coil 29 by operating the handle part 28 to lock respective locking pieces 23, 24. The spring coil 29 can be held on the temporarily fixed positions of the 1st and 2nd frame bodies 11, 12. Since the 1st and 2nd frame bodies 11, 12 for supporting a light source and a mirror which may be easily damaged by vibration or shock are temporarily fixed, the device can be safely transported.
