PROBLEM TO BE SOLVED: To provide a device for correcting a timepiece built in a device, by a standard radio wave, hardly influenced by noise of about 40 kHz generated from electronic equipment or the device itself with the built-in timepiece, hardly causing any delay in transmitting and receiving data and capable of simultaneously correcting timepieces built in a plurality of devices with simple constitution. SOLUTION: This device for correcting the timepiece built in the device, by the standard radio wave receives a long-wave standard radio wave through an antenna, carries out amplification, wave detection and waveform shaping through an amplification circuit, a wave detecting circuit and a waveform shaping circuit and decodes a waveform shaped pulse signal by a decoder part to send correction information such as date and time to the timepiece built in the device. The antenna 11, the amplification circuit 12, the wave detecting circuit 14 and the waveform shaping circuit 15 are constituted as an antenna part 10A independently of the decoder part 10B, and the decoder part 10B is built in the device with the built-in timepiece or installed in the vicinity. The antenna part 10A and the decoder part 10B are connected by a cable 17. |
