PROBLEM TO BE SOLVED: To eliminate the need of providing a dedicated jack for supplying power without requiring housing space more than necessary on a power portion. SOLUTION: A power portion 40 is slid below by being housed in a case body portion 3 when the power portion 40 is housed in an amplifier case. This allows protrusions formed on both side surfaces of the power portion 40 to be engaged with projections 11 and 12, respectively. At the same time, a signal input terminal/power output terminal 42 provided on the lower surface of the power portion 40 is inserted in and connected with a power input terminal 32 provided in an amplifier portion 31. This allows power to be supplied to the amplifier portion 31 from the signal input terminal/power output terminal 42 of the power portion 40. Since space produced by sliding the power portion 40 disappears by closing a lid portion 2, the amplifier case can be miniaturized. COPYRIGHT: (C)2007,JPO&INPIT
