Abstract

PURPOSE:To provide a time service clock amusing a user by making the performance of the clock when a person appears near the clock immediately after the correct-time or when the surrounding of the clock becomes bright. CONSTITUTION:A switch 18 is closed 5min before the correct-time to start the operation of a human body detecting circuit 4 and a brightness detecting circuit 6. When an IR sensor 5 detects a human body or a CdS 7 detects the bright state before the correct-time. The Q output of a flip-flop 10 becomes '1', a control circuit 17 reads out a program A including a time service action from a memory circuit 15 and operates a drive section 14 based on the program A. If the human body or the bright state is not detected before the correct-time and the IR sensor 5 detects the human body or the CdS 7 detects the bright state within 5min after the correct-time, the output of a gate circuit 9 becomes '1', the control circuit 17 reads out a program including no time service action from the memory circuit 15 in response to the count value of a counter 16 at this time and operates the drive section 14 based on the read program.

Further, in the above two embodiments, three kinds of operation programs stored in the storage circuit 15 that do not include the time notification are stored, but the number is not limited to the above, and can be changed appropriately. For example, one operation program that does not include time information may be set to be executed when a human body and a bright state are detected after the hour, and an operation program that does not include time information may be executed. You may make it read each according to the count value of the counter 16 as a kind. Further, the content of the operation program is not limited to the above, and can be changed as appropriate.

In the above embodiment, the performance is executed when the human body is detected and the bright state is detected.
