PURPOSE:To absorb stress during the clamping of a fixing screw and to attain secure fixation without breaking a photosensor by forming a cut in the external surface of a holder to a >=0.5mm. depth and forming a recessed outward shape. CONSTITUTION:The photosensor fixing device is so constituted that the outward appearance of the holder 2 is made recessed by forming the cut 6 at a flank position corresponding to the photosensor. Then, the photosensor 1 is inserted into the grooves of a main body 5 and fitted thereto, and the photosensor is clamped sideward with fixing screws. At this time, even when the clamping force for fixation is applied, the stress is absorbed not to apply direct external force to the photosensor 1 inside the main body because of the presence of the cut 6, and setting the depth of the cut 6 to >=0.5mm. attain the secure fixation without breaking the photosensor. |
