Title:
ELECTRIC SHUTTER
Document Type and Number:
Japanese Patent JP3900445
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric shutter operable from a radio transmitter installed outside.
SOLUTION: A radio transmitter is provided with a code input key in addition to an operation key. Any operation key for ID code, ascent, stop, and descent is pressed at S41 to operate an electric shutter. When ID code coincides with the ID code registered in the radio transmitter, the operation is shifted from S42 to S43 to transmit a transmission signal, but when it does not coincide with the latter, transmission is not done. Moreover, it is unnecessary to input the ID code to stop the shutter. The ID code is read from a memory at S45 and a transmission signal is sent at S46. It is unnecessary to input the ID code to lower the shutter in the same way.
