ABSTRACT:
In a reflector holding structure for a liquid crystal module of a device, first and second lock portions and a positioning hole are formed on a board on which a driving circuit is mounted, and first and second pawls and a positioning pin are formed on a reflector. The first and second pawls are locked to the first and second lock portions, and the positioning pin is fitted in the positioning hole, thereby holding the reflector on the board. The first lock portion is formed in the middle of one end side of the board, and the second lock portion and the positioning hole are formed near two corner portions, on the other end side, which define a triangle together with the first lock portion.In assembling the liquid crystal module, the first pawl is locked to the first lock portion, the second pawl is inserted into the second lock portion, and the positioning pin is fitted in the positioning hole while the reflector is rotated/moved about the first pawl as a fulcrum with the second pawl being locked to the board. With the use of such an arrangement and assembly method, there is provided a reflector holding structure for a liquid crystal module, which has only two lock portions and can easily and reliably attach/detach a reflector, with a compact structure, to/from a board.
