The automatic television control apparatus 1 of the present invention in FIG. 3 has almost the same configuration as that of FIG. 2, but the first, second and third timers 5 are used as the timer 5.
The difference is that it is composed of A, 5B, and 5C. The first timer 5A is a viewing time timer that counts most of the set viewing time, and the second timer 5A
B is an end notice timer that starts with the count-up output signal of the timer 5A and counts the remaining portion of the listening time counted by the timer 5A.
Is a re-listening prohibited period (for example, 12 hours, 18 hours, etc.) that is longer than the listening time that can be set and input by the listening time setting key 3A.
4 is a re-listening prohibition timer that counts
It operates at the operation timing shown in.

First, while the television screen 22 is on, the desired viewing time (for example, 2 hours) is set and input using the viewing time setting key 3A, and the start key 3 is pressed.
When B is turned on, the timers 5A and 5C are started by the control of the microcomputer 4 (time t0 in FIGS. 4A and 4C), and the timer 5A starts counting the set listening time. The timer 5A is, for example, the listening time setting key 3
When the viewing time is set and input in A, it is automatically set so as to count most of the set viewing time. In this example, the set viewing time is 2 hours. Of these, it is set to count up to 1 hour and 55 minutes.

Therefore, the set listening time is 1 hour 55 hours.
After a lapse of minutes, the timer 5A counts up (see FIG.
At time t1 of (A), the timer 5B is started by being triggered by the count-up falling output signal of the timer 5A (time t1 of FIG. 5B)). The timer 5B is automatically set to count the remaining time counted by the timer 5A out of the set listening time, and is set to count the remaining 5 minutes in this example.
As soon as the timer 5B starts counting, the memory 6
The message digital data corresponding to, for example, "It's over!"
After being converted to analog, a message "I'm done" is emitted from the speaker 8 as a voice signal.

This voice message is issued at a predetermined interval (for example, every 30 seconds) while the timer 5B is counting under the control of the microcomputer 4, and stops when the timer 5B counts up. Therefore, the viewer 20 of the television 20 will be informed that the listening time will be over soon and the television screen 22 will be turned off, and he / she will continue to listen to it without hesitation. The power switch 23 can be turned off to stop hearing. If the listener continues to hear,
The timer 5B counts up (time t in FIG. 4B).
2) When the count-up fall output and the detection output of the television operating state detection circuit 2 are both input to the microcomputer 4, a drive signal is supplied from the microcomputer 4 to the infrared signal generator 7, and the infrared signal generator 7 outputs An infrared signal (time t2 in FIG. 4D) is emitted from the LED.

This infrared ray is reflected by the viewer 9 of the television, furniture 10 in the room, etc., enters the light receiving element of the remote control device 21 of the television 20 as reflected infrared light, and the auxiliary power switch is turned off by the operation of the remote control device 21. TV screen 2
2 turns off. Therefore, the viewer 9 can only watch the television for the viewing time set by the automatic TV control device 1, that is, for 2 hours.

On the other hand, the re-listening prohibition timer 5C is the timer 5
It is set to start at the same time as the start of A, and is set to count for a re-listening prohibition period of 12 hours, for example, and while the counting continues, the main power switch 2 of the TV is turned on again.
When the microcomputer 4 confirms that 3 is turned on or the auxiliary power switch is turned on by the remote control transmitter, the microcomputer 4 starts the end warning timer 5B (time t3 in FIG. 4B), and 5 minutes. After that, the drive signal is supplied to the infrared signal generator 7, and L of the infrared signal generator 7 is supplied.
An infrared signal (time t4 in FIG. 4D) is emitted from the ED, and the auxiliary power source of the television 20 is turned off to turn off the screen 22. Therefore, the television 20 cannot be continuously listened to for a long time while the re-listening prohibition timer 5C continues counting. The timers 5A, 5B, 5C can be reset by a reset switch (not shown) of the automatic television control device 1 to wait for the next listening time setting.

Next, the above operation will be described with reference to the flowchart of FIG. First, when the power of the television 20 is turned on (S1), the television operating state detection circuit 2 confirms whether or not the television screen 22 is turned on (S2).
If the screen 22 is on, it is then determined whether or not the re-listening prohibition timer 5C is counting (S3), and if it is counting, the process proceeds to step S6 described later. If it is not counting, the viewing time is set to 2 hours, for example, by the viewing time setting key 3A, and the start key 3B is turned on to start the viewing time timer 5A and the end notice timer 5B (S4). ).

Next, when 1 hour and 55 minutes have passed during the set viewing time, the viewing time timer 5A is turned off (S5), and the end notice timer 5B is started (S5).
6). When the end notice timer 5B is started, the warning signal "Already done" is continuously transmitted at a predetermined time interval (S7). Next, as soon as the end notice timer 5B is turned off (S8), an infrared signal representing the "power off" signal learned from the portable remote control transmitter is transmitted from the infrared signal generator 7 (S9), and the auxiliary power supply for the television 20 is supplied. To turn off the screen 22.

If C is counting, the end notice timer 5B is started, and after steps S7 to S9, the auxiliary power of the television 20 is turned off and the screen 22 is turned off. This is, for example, when the main power supply of the TV 20 is turned on again while the TV automatic control device 1 is operating, and the re-listening prohibition timer 5C is the main power supply of the TV 20 for 12 hours from the initial start. The on / off state of the switch is monitored, and even if the main power switch is turned on again, the television screen 22 is turned off by turning off the auxiliary power source of the television 20 after the end notice timer 5B is counted up (that is, after 5 minutes). Thus, it is possible to prevent the user from watching the television 20 for a long time. In the above description, when the re-listening prohibition timer 5C is counting in step S3, the process proceeds to step S6 to notify the end notice timer 5B.
However, instead of proceeding to step S6, the procedure proceeds to step S7 as indicated by the dotted line in FIG. 5, and a voice signal "already finished" is issued at a predetermined time interval, and then step S8. It is also possible to turn off the auxiliary power source of the television 20 and turn off the screen 22 through steps S9 to S9. As described above, the television screen 22 is turned off after 2 hours, which is the set listening time,
