PURPOSE:To obtain a timecast clock optionally enabled to set up ringing time and ringing stopping time by using a ringing setting board to be revoluted once per 24hr. CONSTITUTION:A ringing setting board 9 is rotated once per 24hr in one united body with a ringing wheel 8 to be rotated once per 24hr. The setting board 9 is provided with numerals and grooves 12 corresponding to each time in 24hr. If a band-like part for a required time formed by the groove 12 is bent when the numeral coincides with a prescribed fixed indicator, contacts 11, 11' in a ringing circuit are not connected even at the arrival of the set time and the clock is in the ringing stopped status. By said configuration, required ringing time and ringing stopping time are easily and freely set up. |
