PURPOSE:To improve the quality of an image by providing a couple of stage parts which are formed in a couple of clamping member respectively and extend in the array direction of convergent optical transmitters, and a couple of engagement members which engage those stage parts and spread almost at right angles to the axial center of the convergent optical transmitters. CONSTITUTION:The stage parts 14 are formed by cutting corner parts of the clamping plates 13 on the sides opposite to contacting surface for transmitters 4 and on one terminal surface side of the transmitters 4 in a quadrangular prism shape in the array direction of the transmitters 4, i.e. in the lengthwise direction of the clamping plates 13 to the overall length. Those stage parts 14 face each other with the transmitters 14 between, and a couple of engagement plates 15 formed of metal such as stainless steel, aluminum alloy, and iron or FRP, etc., in a rectangular plate shape are engaged with those stage parts 14 while spreading almost at right angles to the axial center of the transmitters 4 and almost in the same plane; and two screw holes 15a are formed in those engagement plate 15 and screws 16 are inserted threadably to fit the engagement plates 15 to a base plate, etc. |
