Abstract

PURPOSE:To inform whether the number of music possible to be set of a random memory set is within the range of an address to an operator by providing a sound or a display output function to confirm the acceptance of an operation when a random memory function and an operation switch are operated. CONSTITUTION:In an optical disc is reproducing device having the sound or the display output function to confirm the acceptance of the operation when the random memory function and the operation switch are operated, when the additional set of the random memory is permitted, a confirming sound to recognize the depression of a set which in a setting time is generated, and when it is not permitted, the generation of a confirming sound is terminated. As for the hardware constitution of a player, no modification on a hardware is necessary when the hardware is equipped with the random memory function and also a function which can generate the confirming sound at every acceptance at the player side when the operation switch is depressed, and it is enough only that some programs are added on the programs in a controlling microcomputer built in the player.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a random memory function in an optical disc playback device such as a digital audio disc player.

(Prior Art) Conventionally, when setting the random memory of a CD player, there is a display section that displays the number of songs stored in random memory. It was determining whether or not it was possible to set the memory.

(Problems to be Solved by the Invention) With the above configuration, for example, in a car-mounted CD player, the area that can be used as an operation and display section is small, and it is not possible to provide a display section for the number of songs stored in random memory as described above. It was possible.

An object of the present invention is to eliminate the drawbacks of the prior art, and to emit a recognition sound to confirm that the set switch has been pressed when additional setting of random memory is possible, and to emit a recognition sound to confirm that the set switch has been pressed when additional setting of random memory is possible. An object of the present invention is to provide an optical disc playback device that stops generating a confirmation sound.

(Means and effects for solving the problem) The optical disc playback device of the present invention has a random memory function and an operation switch when the operation switch is operated.

It has a sound or display output function to confirm the reception, and when a random memory set operation exceeding the capacity of the random memory is performed, a sound or display confirming the reception of the operation switch for the random memory set. The output will stop.

(Example) An embodiment of the present invention will be described based on the drawings.

The player's hardware configuration has a random memory function,
If the operation switch is pressed and a confirmation sound is generated each time the player accepts this, simply add a copy of the control microcomputer program built into the plate without changing the hardware. It is possible to implement the present invention with just one.

The procedure of random memory set processing according to the present invention will be explained below.

In the figure, in (1) it is checked whether any of the operation switches has been pressed, and if it has not been pressed, other processing (B
). If it is pressed, ask whether the pressed switch is a random memory switch in (2), and if it is not a random memory switch, proceed to another process (C), and if it is a random memory switch, proceed to (3). , and (4)
When the random memory switch is pressed in
Ask whether it is during play or in any other case, and if it is during pause, it is assumed that it is a random memory set operation and processing (
5) Transfer. If the game is being played, in order to reset all the random memories that have been set so far, the content of the RAM that stores the number of random memory songs is set to 0 in step (6), and the process is moved to step (7). In process (5), until now random
Number of memorized songs N is random Maximum number of songs that can be memorized N
If it is less than max, it is determined that further random memory is possible, and in step (7), the song number displayed in the song number display section is stored in the RAM in correspondence with the random memory N. and then process (8)
The value of N is incremented by one, the process proceeds to process (9), a confirmation sound is generated to acknowledge that the random memory switch has been pressed, and the process proceeds to another process (D). (3), (4
), when the game is neither paused nor playing, the process proceeds to process (D) without performing a random memory operation or a random memory set operation.

In the case of process (5), when N≧Nmax, it is impossible to set any more random memory, so store operation to the RAM of the track number displayed on the display and confirmation of random memory switch acceptance. If there is a sound generating action, the process proceeds to process (D).

The configuration and operation of the present invention have been described below by taking a CD player as an example, but the same configuration can be applied to other optical playback devices.

(Effects of the Invention) According to the present invention, as a method for informing the operator whether or not the number of songs that can be set in a random memory set is within the range of addresses, the microcomputer in the hardware can be used without changing the hardware configuration. It can be implemented by only changing a part of the program, and it can be used in optical playback devices, especially small optical playback devices for vehicles, and has great practical effects.

Claims (1)

[Claims] When a random memory function and an operation switch are operated, a random memory set operation that exceeds the capacity of the random memory is performed in an optical disc playback device that has a sound or display output function to confirm acceptance. An optical disc playback device characterized in that when the random memory set switch accepts a confirmation sound or outputs a display, the output of the switch stops.
