Display the characters. Next, when you operate the channel selection key 4,
Unlike (A) above, the control circuit 11 includes a channel selection section 16.
Instead of outputting a channel selection signal, the receiving channel data to be stored in the receiving channel storage circuit 12 is output. As a result, the reception channel data is stored in the reception channel storage circuit 12. On the other hand, the received channel data is also given to the display circuit 20 as display data by the control circuit 11, and the display data is displayed on the screen of the CRT 22 as shown in FIG. 2(b) in the same manner as described above. "4" is displayed. Next, when the reservation time setting key 5 is pressed repeatedly, the remote control signal corresponding to the operation of the reservation time setting key 5 is processed by the control circuit 11 in the same manner as described above, and the reservation time is processed as reservation time data. The data is stored in the memory circuit 13. In this case, when the reservation time setting key 5 is operated once, the reservation time data is, for example, "1", and when it is operated twice, the reservation time data is "2", and when the reservation time setting key 5 is operated n times. In this case, the reservation time data is "n". FIG. 2(c) shows that when one operation of the reservation time setting key 5 corresponds to a reservation time of 15 minutes, the reservation time open setting key 5 is operated four times, and therefore the reservation time data of 60 minutes is obtained. It shows that. Note that when one operation in the reservation time setting mode is completed, the same operation as described above is repeated again, and the reservation time is set in accordance with the number of repetitions.

Figure 2 (d> is the CR when the operation is repeated four times.
The display state on the screen of T22 is shown. That is, the second
In Figure (d), the first operation changes the reception channel to 4 and its reservation time is 60 minutes, and the second operation changes the reception channel to 8 and its reservation time to 15 minutes.
The third repetition shows that the receiving channel is 5 and the reserved time is 30 minutes, and the fourth repetition shows that the receiving channel is 1 and the reserved time is 120 minutes.

(C) Timer operation mode To set this timer operation, for example, operate the mode key 5 twice in succession. This causes the control circuit 11 to enter the timer operation mode using a remote control signal corresponding to the operation. In this timer operation, the control circuit 11 reads the reception channel data stored in the reception channel storage circuit 12 and supplies it to the tuning circuit 16 as a tuning signal. At the same time, the reset signal is sent to the first. Each counter 14b, 14c is reset by applying the signal to the second counter 14b, 14c. In this way, the timer operation is started.

The first counter 14b is a 15-minute counter, starts counting in response to the clock from the clock oscillator 14a, and sends the count output to the second counter once every 15 minutes.
14c. The second counter 14c outputs time measurement data corresponding to the count to the comparison circuit 15. The comparison circuit 15 is also supplied with reservation time data from the reservation time storage circuit 13 . The comparison circuit 15 outputs a comparison signal to the control circuit 11 when the reservation time data and time measurement data match.

For example, when the reservation time data is "4", which is 60 minutes, and the time measurement data is "4", the comparison circuit 15 outputs a comparison signal. When the control circuit 11 receives the comparison signal, the control circuit 11 controls the receiving channel storage circuit 1.
The next received channel data is read out from 2, and a corresponding tuning signal is output to the tuning circuit 16. The channel selection circuit 16 outputs a video signal corresponding to the channel selection signal to the CRT driver 17. In this way, desired program broadcasts are displayed one after another on the CRT 22 in accordance with the reserved time. The control circuit 11 also provides a power supply control signal to the power supply circuit 21, and when reception channel data and reservation time data are no longer obtained, the control circuit 11 supplies a power supply control signal to the power supply circuit 21 and turns it off.

(Effects) As described above, according to the present invention, in a television receiver including a television 7B receiver body and a remote control device that sets a timer for the reception operation of the television receiver body by remote control, the remote control device , a tuning key operated to select a reception channel, a mode key operated to enter a reservation time setting mode for the selected reception channel, and a television broadcast on the selected reception channel.
