PROBLEM TO BE SOLVED: To prevent a general user from executing the inadvertent operation of a wiring board or electronic parts and to prevent the occurrence of fault caused by the inadvertent operation by normally concealing an outside checking window of a cover through the user of an opening/closing body concerning the wiring board and the electronic parts which are not required handled by the general user. SOLUTION: The outside checking window 33 is provided in the outer surface part 32a of the cover 32 easy to be operated by the user easily, and a super G3 boards 51 and 53 are provided so as to face it, so that the boards which can be handled by the general user are attached/detached without removing the cover 32 from a board arranging part 31. Since the handling of an ROM 59 or a display switch 60, etc., requires a special service man, the checking window 38 therefor is provided in an inner part 32b which is not normally seen from the outside of the cover 32, the checking window 38 is concealed with an upper part panel 22 which is closed in a device usage state and the erroneous operation of the ROM 59 or a dip switch 60 by the general user is disenabled. Therefore, fault occurrence due to the inadvertent operation of the wiring board or the electronic parts by the general user is prevented. |
