Abstract

(57) [Summary] [Purpose] To prevent falling asleep with the television receiver on. [Structure] The television receiver is provided with an illuminance sensor 7,
Detects ambient brightness. When the illuminance sensor 7 detects that the user has darkened the room illumination, the control device 4 immediately or after a while using the timer device 5, turns off the power of the television receiver.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a television receiver.

[0002]

[Prior Art]

 FIG. 3 is a schematic configuration diagram of a conventional television receiver. The antenna 1 is connected to the signal processing circuit 2 and further connected to the CRT 3. The power switch 6 is connected to the control device 4 and further connected to the signal processing circuit. Moreover, the timer device 5 is connected to the control device 4.

Next, the operation will be described. The signal received by the antenna 1 is appropriately processed by the signal processing circuit 2 and an image is obtained on the CRT 3. When the user turns the power switch 6 on and off, the control device 4 turns the television receiver on and off. Further, by properly setting the timer device, the control device 4 turns off the power after a fixed time.

[0004]

[Problems to be solved by the device]

 With conventional television receivers, for example, when watching TV at night, it is necessary to turn off the power switch or set a timer before going to bed. The power of John's receiver was left on. As a countermeasure against this, there is an idea to automatically turn off the power when the end of broadcasting is detected, but it is not effective when broadcasting continues late into the night as in recent years.

The present invention has been made to solve the above-mentioned problems, and even if the user forgets to turn off the power of the television receiver and goes to sleep, the power of the television receiver remains on all night. The purpose is to prevent.

[0006]

[Means for Solving the Problems]

 The television receiver according to the present invention is equipped with an illuminance sensor, and the illuminance detection output controls the power on / off.

[0007]

[Action]

 When the illuminance sensor according to the present invention detects that the surroundings of the television receiver have become dark, the control device turns off the television receiver immediately or after a certain period of time.

[0008]

【Example】

 Example 1. An embodiment of this invention will be described below with reference to FIG. The basic configuration is the same as the conventional example, except that the illuminance sensor 7 is connected to the control device 4. The illuminance sensor 7 connected to the control device 4 detects the illuminance around the television receiver.

In normal use, the surroundings of the television receiver are usually moderately bright, and the operation at this time is no different from that of the conventional television receiver. When the nighttime user dims the room light when going to bed, the illuminance sensor 7 informs the control device 4 that the illuminance has become dark. In response to this, the control device 4 determines that the user has finished viewing the television receiver and turns off the power of the television receiver.

Example 2. In the above embodiment, the power of the television receiver is immediately turned off when the room becomes dark, but the timer device 5 of the control device 4 may be used to turn off the power after a while. Good. In this case, the user can sleep while watching the broadcast.

Example 3. Further, the illuminance sensor 7 and the control device 4 may be built in a remote control transmitter which is popular in recent years.

Example 4. As shown in FIG. 2, by disabling the illuminance detection function by disabling the switch 8, the television receiver according to the present invention can be viewed even in a dark room.

[0013]

[Effect of the device]

 As described above, according to this invention, the illuminance sensor is added to the television receiver so that the power is turned off immediately or after a certain period of time when the surroundings of the television receiver become dark. , It can prevent you from forgetting to turn off the television receiver and falling asleep.
