1 is a schematic configuration diagram of a video recorder / player equipped with a preferred embodiment of a power control device of a video recorder / player according to the present invention, and includes seating, loading, driving, and ejecting an inserted video tape. A deck portion (DECK) 10 for performing operations such as capstan motor control; A servo unit (SERVO) 20 for controlling the speed of the video tape and drum motor inserted into the deck unit 10; A tuner unit (TUNER) 30 for tuning the broadcast received from the outside; A broadcast information detection unit (40) for detecting a broadcast information (VPS / PDS) signal included in the signal from the broadcast signal tuned by the tuner unit 30; A Y / C unit 50 for converting a playback signal of a video tape inserted into the deck unit 10 and a signal selected from the tuner unit 30 into a video signal; An OSD unit 60 for displaying overall settings of the video recorder / player in text; A status display unit 70 for displaying an operation state of the video recorder / player; A microcomputer (1) for controlling the respective components; A remote remote controller 80 and its own key input unit 90 for inputting a command to operate an image recorder / player; A power source (100) for applying power to each of the components; Power supply / blocking control switch SW1 to the Y / C unit 50; And a separate power supply control switch (SW2) independently provided between each component except the Y / C unit 50 and the power supply (100), the power supply control switch (SW1) Is opened and closed by the control signal P1 output from the microcomputer 1, and the power supply control switch SW2 is opened and closed by another control signal P2 output from the microcomputer 1. It is meant to be built.

FIG. 4 is a schematic control flowchart of a method in which a power control device of a video recorder / player according to the present invention is turned off in a low power consumption mode and a reserved recording mode according to a user's selection. With reference to the control flow will be described in detail the operation and low power consumption method of an embodiment configured as described above.

In the power control apparatus of the video recording / playback according to the present invention, when the power key is input by the remote controller 80, the control switch SW1 is not ready for the low power consumption mode, namely, the control switch SW1 without prompting the user's intention. Only the control signal P1 to control is LOW, the control signal P2 to control the control switch SW2 is maintained in a HIGH state to cut off only the power supply of the Y / C unit 50 and continue to supply power to other components Will be supplied. In order to be in the low power consumption mode instead of the reserved recording mode, the video recording / playback must be input through the power key of the own key input unit 90 provided in the player itself.

Once the power key on its own key input unit 90 is input by the user, the microcomputer 1 detects the input of the power key (S101) and then checks whether the power is currently supplied to the video recorder / player. (S102). At this time, if the power of the current video recorder / player is not turned on, the microcomputer 1 determines that the power key input of the user is the first power key input for supplying power to the video recorder / player. The control signals P1 and P2 are all set to HIGH so that power can be supplied to each component of the recording / reproducing apparatus, and the flow is output (S117) to the control switches SW1 and SW2 (S110).

However, if the power of the current video recorder / player is confirmed as being applied in the video recording / player power check step (S102), the microcomputer 1 again switches to the low power consumption mode, the operation power off and the scheduled recording mode. The variable related to whether the guidance message for outputting the operating power is output is read to determine whether the guidance message is output (S103). At this time, if the guidance message is currently output to the image display device B, the microcomputer 1 inputs the second power key as the power key input of the user selects the low power consumption mode according to the guidance message. In this case, the control signal P1 for controlling the control switch SW1 is output low (S107), and then the video tape in the deck is brought to the STOP position, or the drum DRUM is rotated. After stopping the deck unit 10, the servo unit 20, and each component (S108), and finally outputting a control signal P2 for controlling the control switch SW2 to LOW (S108). S109), the operation power of the video recorder / player is cut off in the low power consumption mode and the flow ends. As a result, much less power is consumed in the operation power-off state than in the conventional video recorder / player. 3 illustrates a process in which the control signals P1 and P2 change with time according to the above operation.

However, if the guidance message output confirmation step (S103), it is confirmed that the guidance message is not currently output to the image display device (B), the microcomputer (1) is the power key input of the user to cut off the operating power Judging by the first input for the purpose, as shown in Fig. 7, the image data (P3) of the guidance message that allows the user to select between the low power consumption mode operating power cut-off and the reservation recording mode operating power cut-off is finally imaged. After outputting (S104) on the display device (B), it is displayed as a guide message is output to the guide message output variable (S105), and sets the key input waiting time in case there is no key input from the user (S106). After that, go back to the initial start step and repeat the user's key input and wait time end loop repeatedly to decrease the set wait time. do. (S101, S111, S112, S113, S114, S110)

While the microcomputer 1 performs the loop, when the user who sees the guidance message inputs the power key again in order to shut down the low power consumption mode operation power, the microcomputer 1 records an image as described above. The operation power is cut off in a low power consumption mode in which both the control switches SW1 and SW2 are opened through the player / player power checking step S102 and the guide message output checking step S103. (S107, S108, S109, S110)

However, if the power key is not input from the user while the loop is in progress, the microcomputer 1 checks that the standby time setting value is 0 in step S113 of checking the waiting time, and thus the microcomputer 1 ) Determines that the user does not want to shut down the operation power in the low power consumption mode state, so that only the control signal P1 for controlling the control switch SW1 is LOW, and the control signal P2 for controlling the control switch SW2. Is maintained at HIGH (S115) to cut off the power of the Y / C unit 50 and to cut off the power in the reserved recording mode in which the other components continue to be supplied with power.

FIG. 5 is a schematic block diagram of a video recorder / player equipped with another embodiment of a power control device of a video recorder / player according to the present invention, and is supplied with power controlled by the control signal P2 output from the microcomputer 1; FIG. The control switch SW2 is connected only to the deck unit 10, the servo unit 20, and the OSD unit 60, and the control signal P3 is provided to the tuner unit 30, the broadcast information detection unit 40, and the status display unit 70. A separate power supply control switch SW3 is controlled by ().

In the video recorder / player configured as described above, the control signal P2 for controlling the power supply control switches SW1 and SW2 and the power supply control switch SW3 are controlled in the low power consumption mode. Outputs all the signals P3 to LOW to minimize the power consumed when the operation power is cut off, and when the user selects the power-off in the reserved recording enabled mode, unlike the embodiment of FIG. By only outputting the control signal P3 for controlling the power supply control switch SW3 to HIGH to apply power to the power, the power consumed in the reserved recording possible state is further reduced.

The apparatus and method for controlling power of an image recorder / player according to the present invention configured and acting as described above can cut off the operation power with a low power consumption, as well as make a reservation according to a user's selection according to a guide message. The invention has the effect that the operation power can be cut off in the state capable of recording.
