PURPOSE:To enable a plurality of devices to be operated remotely and separately, by synthesizing a device selecting signal and an X-ray radiating signal, transmitting them, and radiating X-ray only when the device selecting signal coincides with a previously determined device signal in an X-ray receiver. CONSTITUTION:As a photographing preparing switch (S1) is closed, a key signal set by a key signal setter 1 and an X-ray photographing signal which is based on a second switch signal of an X-ray radiation switch (S2) are received by a receiving circuit 14 through antenna 6, 13, converted to a parallel signal with a pulse signal converting circuit 29, and the coincidence of transmitted key signal with the key signal which is set in the key signal setter 27 of the X-ray device is checked by comparison in a discriminator 24. Then, if the X-ray radiating switch (S2) is closed, a final bit of a parallel-series converting circuit 23 is lifted to high level and transmits its output to an X-ray radiating circuit 25, and X-ray is radiated only when coincidence signal is inputted from the discriminator 24. |
