Control the power supply of each unit of the power supply unit 60, control the signal selection of the video signal processing unit 20 and the audio signal processing unit 40, and supply the first control signal C1 to the compact disc player unit 30. .

However, in some cases, the CD door closing command is not input through the remote control or the control box of the TV control unit while the CD door of the compact disc player integrated television receiver is improved. At this time, if only relying on the user's operation, the CD door is left open for a long time, it may be soiled by dirt, such as dust or cause a failure.

Accordingly, an object of the present invention is to provide a method of automatically closing a CD door of a compact disc player integrated television receiver, which automatically closes the CD door when the CD door of the compact disc player integrated television receiver is continuously opened for a predetermined time or more. It is.

In order to achieve the above object of the present invention, the automatic CD door closing method of the compact disc player integrated television receiver according to the present invention is characterized in that the compact disc player integrated television receiver comprises a TV microcomputer in the television control unit and a CD microcomputer in the compact disk player unit. A CD door automatic closing method for automatically closing a CD door when the CD door is open, the method comprising: determining whether a CD door closing status signal from the CD microcomputer or a CD door closing command is input from an IR receiver in the television control unit; And closing the CD door when the CD door closing state signal and the CD door closing command are not input after a predetermined time elapses or when the CD door closing command is input.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

FIG. 2 shows a part of the configuration of the compact disc player integrated television receiver of FIG. 1 to explain the CD door automatic closing method of the compact disc player integrated television receiver according to the present invention.

In order to avoid duplication of description, the same reference numerals are used.

The TV microcomputer 52 refers to a microcomputer in the television control section 50 of FIG. 1, and performs a function of collectively controlling each part of the television receiver integrated with a compact disc player. The CD microcomputer 32 refers to a microcomputer in the compact disc player unit 30 of FIG. 1, and performs a function of controlling each part of the compact disc player unit 30. As shown in FIG. The CD door controller 70 outputs a CD door control signal through the terminal 72, receives a CD door open / closed state signal through the terminal 74, and a disk presence state signal on the deck through the terminal 76. At this time, the TV microcomputer 52 and the CD microcomputer 32 input and output mutual control data through the terminal 58 and control signals relating to the CD door through the terminal 59. In addition, the CD microcomputer 32 and the CD door control unit 70 input and output CD door related control data through the terminal 35. The user opens or closes the CD door by pressing the CD door open / close key of the remote control 55 or the control box 57 in the receiver.

For a more detailed operation, it will be described with reference to the flowchart of FIG. 3.

3 is a flowchart for explaining a method of automatically closing a CD door of a compact television player integrated television receiver according to the present invention.

First, it is determined whether the CD door is closed. That is, a control signal indicating the CD door closed state is input from the CD microcomputer 32 or the CD door is closed by the select key of the remote controller 55 or the control box 57. If it is in the state, it stores the CD door closed state in the TV microcomputer 52. Therefore, the stored state of the TV microcomputer 52 is searched to determine whether the CD door is closed (CD closed or not determining step 310). Subsequently, it is determined whether the CD door closed state signal is input from the CD microcomputer 32. That is, not only the CD door is closed by operating keys on the remote control 55 or the control box 57, but also the CD door may be manually closed. Therefore, in this case, the CD door open / closed state input to the CD door control unit 70 is transmitted to the TV microcomputer 52 through the CD microcomputer 32. Accordingly, the TV microcomputer 52 determines whether the CD door open / close state signal indicates the CD door closed state (step 320 for determining whether the CD door is closed). Subsequently, if the state signal is not input, it is determined whether the CD door closing command is input from the IR receiver. That is, the IR receiver 54 is turned on by pressing the CD door closing state key of the remote controller 55 or the control box 57. The CD door closing command is transmitted to the TV microcomputer 52. Accordingly, the TV microcomputer 52 determines whether the CD door closing command has been transmitted (step 330 of determining whether the CD door closing command is input). Subsequently, if the close command is not input, it is determined whether a predetermined time has elapsed. That is, it is determined whether the CD door remains open even after a predetermined time has elapsed (step 340 for determining whether a predetermined time has elapsed). Then, if the predetermined time has elapsed, the CD door is closed. That is, the TV microcomputer 52 closes the CD door by controlling the CD door control unit 70 through the CD microcomputer 32 (closing the CD door 350.) In the determination step 310, the CD door is closed. Or when the CD door closing status signal is input in the determining step 320. When the CD door closing command is input in the determining step 330, the process jumps to the closing CD door 350. If the predetermined time has not elapsed in the determination step 340 of the predetermined time elapsed, the process jumps to the determination step 320.

As described above, the present invention automatically closes the CD door when the CD door remains open even after a predetermined time has elapsed in the compact disc player integrated television receiver. Therefore, when the CD door is left open for a long time, there is an effect that the cause of failure due to foreign matter such as dust can be removed.
