Claims (1)

[Scope of utility model registration request] Twelve contacts are formed on one circumference of the board corresponding to the index positions from 1 to 12 o'clock, and among these contacts, the contacts corresponding to the index positions at 1 o'clock and 12 o'clock are connected to the power supply terminals. A resistor provided between each contact, a contact piece that can make elastic contact with each contact, and one of the board and the contact piece is rotated in conjunction with the rotation of the hour hand, and the contact piece is connected to the contact piece. A moving device that relatively slides on the contacts, a detection device that detects the hour, a clock pulse generation circuit that generates clock pulses based on the output of this detection device, and a clock pulse generation circuit that counts the clock pulses and responds to the counted contents. A code signal generation circuit that generates a code output, a D/A conversion circuit that converts the output of the code signal generation circuit into an analog signal, and a comparison in magnitude between the output of the contact piece and the output of the D/A conversion circuit. a memory circuit that stores the output of the code signal generation circuit based on the output from the comparison circuit; and a time signal circuit that reports time based on the contents of the memory circuit.
