Abstract
PURPOSE: To make easy removal of the light source and to always keep the distance between the fiber beginning end and the light source constant, by enabling to mount the light source on the concave of the alignment member elastically.
CONSTITUTION: The light in ring shape from the light source 7 is fed to the projection outlet 16 with optical fiber bundle 9, the reflection light from the bar code is fed to the photo detection element 19 via the lens system 18, the reflection light is converted into electric signal with the element 19, and it is outputted to the cable 23 via the amplifier 22. The light source 7 is placed under the main body 1 and it is held between the conductive ring 10 mounted on the external circumference of the chip 8 and the elastic terminal board 11 fixed on the main body 11. In this holding, the cover 6 provided with the main body 1 is opened, the both ends of the light source 7 are inserted between the terminal board 11 and the concave 10' of the ring 10, enabling to ease of removal by the eleasticity of the terminal board 11. Further, the alignment with the fiber bundle 9 inserted to the chip 8 is made by the concave 10' to always keep constant the distance between the fiber beginning point and the lamp 27.
