PROBLEM TO BE SOLVED: To provide a transmitter designed while taking convenience and operability for an operator into consideration as a transmitter used to open and close a plurality of shutter devices by itself.SOLUTION: There is provided a transmitter which includes a plurality of actuation switches corresponding to a plurality of shutter devices one to one, one closure switch, one stop switch, radio signal transmission means of transmitting a radio signal to the shutter devices, and control means of determining the radio signal transmitted from the radio signal transmission means according to a switch input. The control means is configured to select a corresponding shutter device with an input from the actuation switch, and to make effectively an input for an opening operation using an opening switch and an input for a closing operation using a closing operation only within a validity time as a constant time from the input from the actuation switch, and to make effective and process other inputs except the inputs for the opening operation and closing operation as inputs corresponding shutter devices selected right before the other inputs. |
