Abstract

PURPOSE:To look and listen a desired channel without forgetting by outputting at least one of sound and light when sound or image data has been already outputted at a set time. CONSTITUTION:The output start time stored in a memory circuit 1 is compared with the time of a time-piece 2 by a comparing circuit 3 and, when both times coincide, a coincidence signal 4 is inputted to an output control circuit 5 and an output start signal 6 is issued. In such a case that the output start signal 6 has been already outputted when the coincidence signal 4 is inputted, that is, in such a case that sound or image data has been already outputted when a set time arrives, a detection signal 8 showing that the coincidence signal 4 is inputting during the output of the output start signal 6 is inputted to a sound emitting means 9 and a light emitting means 10 by a coincidence detection circuit 7. As mentioned above, by urging the alteration of a channel by appealing to the ear or eye by outputting sound or light, the looking and listening of a desired channel can be performed without forgetting.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ON timer circuit used in televisions, radios, etc.

[Prior Art] In a conventional ON timer circuit, no special operation is performed if audio or video information has already been output when the set time has elapsed.

[Problem to be Solved by the Invention] However, the above-mentioned conventional technology has a problem in that if information is being output for a channel different from the channel that the user intended to view in advance, the viewing opportunity is often missed. .

Therefore, the present invention is intended to solve such a problem, and its purpose is to make it possible to watch a desired channel without forgetting to watch it. The timer circuit is characterized in that it outputs at least one of sound and light when audio or video information has already been output when a set time has elapsed. An example of the invention is shown.

A comparison circuit 5 that compares the output start time stored in the memory circuit 1 with the time of the clock 2 inputs a coincidence signal 4 to the output control circuit 5 when the times match, and outputs an output start signal 6.

If the output start signal 6 has already been output when the coincidence signal 4 is input, that is, if the audio and video information have already been output when the set time has come, the coincidence detection circuit 7 A detection signal 8 indicating that the coincidence signal 4 has been inputted while the output start signal 6 is being outputted is inputted to the sounding means 9 and the light emitting means 10, and sound and light are outputted.

[Effects of the Invention] As described above, according to the present invention, the output of sound and light appeals to the auditory and visual senses, and by prompting the user to change channels, the user does not forget to watch the desired channel. have
