DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described based on one embodiment shown in the drawings. In FIG. 1, reference numeral 1 denotes a garage shutter installed at an entrance of a garage (not shown). The garage shutter 1 is a shutter curtain 3 which is provided in a shutter case 2 and includes a large number of slats.
And an electric shutter comprising an electric switch 4 and a receiving unit 5 of a specific low-power remote control device 5 described later.
a and a receiving antenna 6 to form a remotely operable shutter. Reference numeral 7 denotes an operation box disposed in the vicinity of the garage shutter 1 and used for manual operation thereof, A denotes a tuner of the receiving unit 5a, and B denotes a safety breaker of a power control panel (not shown).

Reference numeral 5b denotes a transmitting section of the specified low power remote controller 5, and the transmitting section 5b includes an open switch 8 and a close switch 9
When the driver of the mobile vehicle turns on the open switch 8 of the transmission unit 5b from inside the vehicle toward the garage, the vehicle goes out of the vehicle and the operation box 7 is formed. The shutter curtain 3 can be opened and the moving vehicle can be housed in the garage without manual operation.

Next, the control operation of the specified low power remote controller 5 will be described with reference to FIG. Here in the figure,
