This remote control device 1 (child device) includes an operation switch (not shown) on the front surface of remote control device main body 2, and has an antenna 3 on the upper surface for communicating with the parent device. This remote control device 1 is portable, and can be hooked on a belt or the like of a wearer by a belt clip 4 attached to the back surface of the remote control device main body 2 with screws 5. Further, since the remote controller 1 is portable, a small battery 8 such as a coin-type dry battery or a rechargeable battery is used as a power source.

A battery 8 serving as a power source of the remote control device 1 is housed in a battery storage section 6 provided on the rear surface of the remote control device main body 2, and is held by attaching a battery cover 7 from above. Since the battery cover 7 is exposed on the back surface of the remote control device 1, for example, when the coin is inserted into the groove 7a and pushed around by about 90 degrees, it comes off from the remote control device main body 2,
When it is inserted into the battery storage section 6 and turned about 90 degrees in the opposite direction, it can be attached to the remote control device main body 2 so that the battery can be easily replaced.

[0004] Although not shown, there is also a remote control device in which a battery cover is slid to be attached to a remote control device main body, and a battery accommodating portion containing a battery is closed by the battery cover. Even in such a remote control device, the battery can be easily replaced.
