In this case, the same reference numerals will be used to help understand the same components as those of the prior art.

First, the key input unit 100 includes a plurality of function keys including a play key, and generates and provides a key signal corresponding to a user's key operation to the system controller 200.

The system controller 200 controls the overall operation of the optical disc player 300 in response to a key signal provided from the key input unit 100 and a signal provided by each component of the optical disc player 300, and in particular, the optical disc player By comparing the information provided from the counter 400 with the power automatic off time stored in the storage unit 500 with respect to the time when the 300 enters the stopped state, a warning about the automatic power off before the power is automatically turned off The speaker 700 is controlled to output sound.

The optical disc player 300 performs an overall operation of the optical disc player 300 such as playing a disc under the control of the system controller 200.

The counter 400 counts the time for which the optical disc player 300 maintains the stationary state under the control of the system control unit 200, and provides the counted time information to the system control unit 200.

The storage unit 500 stores a warning message for power off in advance as voice information or music information, and also presets for outputting preset time data and warning messages for automatically turning off the optical disc player 300. Data on the alarm start time is stored.

The power supply unit 600 supplies predetermined power required for the optical disc player 300 to operate under the control of the system control unit 200.

The speaker 700 outputs, as a sound, a predetermined warning message for power off drawn from the storage 500 under the control of the system controller 200. At this time, the warning message for the automatic power off may be voice information for a predetermined sentence, or may be a predetermined music or melody to call the user's attention.

Hereinafter, the power-off warning method of the optical disc player according to the present invention implemented in the hardware composed of the above-described members will be described in detail with reference to FIG.

3 is a detailed flowchart illustrating a power off warning method of an optical disc player according to the present invention.

First, during the normal operation of the optical disc player 300 while the optical disc player 300 is in a power-on state (S10), a stop key signal is input from the key input unit 100 by a user's key operation, or another external When the optical disc player 300 is stopped due to a factor (S20), the system controller 200 controls the counter 400 to start counting.

Under the control of the system control unit 200, the counter 400 starts counting, and provides the system control unit 200 with a stop time that counts the time that the optical disc player 300 maintains the stop state. 30)

The system controller 200 compares the stop time provided by the counter 400 with the automatic power off time drawn by the storage 400 to determine whether the currently counted time reaches a preset warning start time (S). 40). In this case, the automatic power off time drawn out from the storage unit 400 refers to a preset time to automatically power off when the optical disc player 300 continues to stop without generating a new key signal from the key input unit 100. The preset warning start time refers to a preset time for outputting a warning message for power off so that the user recognizes that the power is automatically turned off.

As a result of the determination in step S 40, when the stop time provided by the counter 400 reaches the warning start time, the system controller 200 stores data including voice, melody, or music for the power-off warning message in the storage 500. And the speaker 700 is controlled to output the data extracted from the storage unit 500 as sound.

In the speaker 700, under the control of the system controller 200, a warning message for the power off, which is drawn out from the storage unit 500, is output as a sound (S50). At this time, if the warning start time is set to 10 seconds before the power off time, the warning message may be displayed as voice information such as 'I will power off after 10 seconds' or '10, 9, 8, 7, You can also output a voice that counts in descending order for the remaining time, such as ..... '. You can also output any measure of music, such as a song, pop, or classic, to let the user know that it is automatically powered off.

On the other hand, in order to enhance the warning effect to the user, the optical disc player 300 is set as the warning start time from the time when the operation is stopped, the preset auto power off time is set to 0, and the countdown is made in descending order from the warning start time. May be output as a voice, and in order to reduce unnecessary power consumption, it may be set to a relatively short time such as 10 seconds or 20 seconds in proximity to the auto power off time.

Thereafter, in step S50, while the power-off warning message is output as sound through the speaker 700, the system controller 200 checks whether a predetermined key signal is generated from the key input unit 100. 60)

If a predetermined key signal is generated from the key input unit 100 as a result of checking in step S60, the system controller 200 causes the optical disc player 300 to perform an operation corresponding to the key signal generated from the key input unit 100. The optical disc player 300 will perform a predetermined operation corresponding to the key signal generated by the key input unit 100 under the control of the system controller 200 (S 70).

On the other hand, as a result of the check in step S60, if no key signal is generated from the key input unit 100 until the automatic power-off time is reached (S80), the system controller 200 is supplied to the optical disc player 300. The power supply unit 600 will be controlled to cut off the power, and the power supply unit 600 will cut off the power supplied to each component member of the optical disc player 300 under the control of the system controller 200.

Therefore, the power supply of the optical disc player 300 is turned off (S90).

According to the present invention, the descending counter for the remaining time until the automatic power-off for a predetermined time for a predetermined time from the time when the optical disc player 300 is stopped, the key signal is not generated for a predetermined time and automatically turned off. By outputting a predetermined power off warning message as a sound through the character information to turn off the power of the optical disc player 300, the user can be notified that the optical disc player 300 is automatically powered off. There is an effect that can prevent the power off of the player 300. That is, by using the present invention, there is an effect that can improve the ease of use of the optical disk player 300.
