PROBLEM TO BE SOLVED: To allow for removal of an electronic circuit unit and a power supply from a case.SOLUTION: To the lower part of a case body 3, an amplification unit 30 is attached while being embraced by two-stage claw pieces 12b, 13b formed on the left sidewall 12 and right sidewall 13 of the case body 3. To the upper part of the case body 3, a power supply 40 is attached while being embraced by press claw pieces 12a, 13a formed on the left sidewall 12 and right sidewall 13. The power supply 40 and the amplification unit 30 can be removed from the case body 3, by widening the interval of the left sidewall 12 and right sidewall 13 of the case body 3. |
