PURPOSE:To transmit display signals consecutively with a simple constitution by detecting the end of one set of display signals outputted from a transmission means, transmitting a start signal to the transmission means, and repeatedly transmitting display signal automatically. CONSTITUTION:In addition to the transmission means that transmits a set of display signals S1 associatively with input of a start signal S2, a start signal generation means is provided which transmits a first start signal TS2, to the transmission means associatively with the impressing of power supply voltage Vd and also transmits a start signal S2 to the transmission means at every ending of a suite of display signals S1 to which a display signal S1 outputted by the transmission means is inputted. When the power supply voltage Vd is impressed to the transmitter, the transmission means comes in a waiting status, and at the same time, a first start signal S2' is inputted from the start signal generation means, so that the transmission means starts the transmission of the display signals S1. Thus transmitted display signals S1 are inputted to the start signal generation means, further, a signal generation means transmits a start signal S2 to the transmission means corresponding to the ending time of the one set of display signals S1, then, the transmission means automatically repeats transmission of the display signals S1.
