Abstract
PURPOSE:To enable a clock to be easily switched to an alarm or a conference use, by a method wherein a sounding terminal of a first alarm function is caused to differ from that of a second alarm function. CONSTITUTION:When a time information of a timing circuit 2 goes a time set at a second alarm function circuit 11, a coincidence signal P6 is outputted to actuate an alarm circuit 14. With an alarm stopping switch S2 pressed once, a D-FF 13e receives an alarm stopping detection signal to read data and to close an AND gate 13g and bring an alarm circuit to a stop. When the time information P1 of the timing circuit 2 goes a time set in a first alarm function circuit 10, the alarm circuit 14 operates in a similar manner. With the alarm stopping switch S2 pressed 4 times and released from press, a signal of a H-level is generated at an output terminal Q of a binary counter 13c to close the AND gate 13g and bring an alarm to a stop.
