JPS62121975A - Controller for compact disk player - Google Patents

Abstract

PURPOSE:To attain reproduction from a music number previously registered even in a timer reproduction mode by reading musical program information out of a memory in accordance with a start signal at the time of entering a power source. CONSTITUTION:For setting a music number to be reproduced, an optional music number is inputted through the operation of a musical program setting and inputting part 5, and written in the nonvolatile memory 3. Afterwards, a mode setting and inputting part 4 is operated to set the timer reproduction mode, and the power source of the player concerned is turned off to set a timer. If the power source of the player is again entered by the timer, a microcomputer 2 decides how the input part 4 is set, reads a musical number out of the memory 3 in a reproduction mode, controls a CD reproduction part 1, and reproduces music from the music number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compact disc (hereinafter referred to as CD) player, and particularly to a timer playback control device for starting CD playback at an arbitrary time.

[Conventional technology]

As mentioned above, user's bits are assigned to the CD data frame, and these bits are used to
Each song number information (including the index number within one song) is recorded.

In the -i CD player, when a song number is specified using the keyboard, the specified song number is played based on the above song number information.

However, in the case of a timer playback mode in which CD playback is started at an arbitrarily set time, conventional CD players are configured to start playback from the first song. .

[To the problem that the invention seeks to solve]

For example, when playing a CD on a timer instead of an alarm, it is often a waste to always play from the first song, and cannot meet the various needs of users.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to provide a control device for a CD player that allows playback from a pre-registered number even in timer playback mode. O [Means for solving the problem] Therefore, the present invention provides a non-volatile memory for storing track number information, a track number setting means for loading arbitrary track number information into this memory, and a power source. A control means is provided for reading out the song number information from the memory in response to a start signal at the time of input, and starting the playback operation from the song number.

[Effect]

If arbitrary song number information is written into the memory by the setting means, the song number information will be retained even if the power of the player is turned off. Thereafter, when one power source of the player is turned on by the timer, the control means is operated. [Embodiment] FIG. 1 is a block diagram of an apparatus according to an embodiment of the present invention.

In the figure, (1) is the CD playback unit (including mechanical elements and four-air circuit elements that play CDs), which is the main part of the CD player, and (2) is the core of the control device for the CD playback unit (1). (3) is a non-volatile memo 9% for storing track number information, (4) is a mode setting input section for setting whether or not to perform timer playback, (5)
is a song number setting input section for setting a song number.

Next, the operation of the above configuration will be explained according to the flowchart shown in FIG.

When setting the playback song number during timer playback, as shown in the flowchart (A), first the song number setting input section (5) is operated to input an arbitrary song number. Then, the song number is stored in memory (3).

Finally, the player operates the mode setting input section (4) to set the timer playback mode, turns off the power of the player, and sets the timer.

When the power of the player is turned on again by the above-mentioned timer, the microcomputer (2) 74-4 in FIG. 2(B)
Execute Chard processing. First, the mode setting input section (4
) is set to timer playback mode. If the timer playback mode is selected, the above memory (
The track number is read from 3) and the CD playback section (1) is controlled to start playing from that track number.

In addition, as for the above memory (3), even if the cell itself does not use a non-volatile one, a volatile memory can be used,
It may be made substantially non-volatile by backing it up with a battery.

In addition to the above embodiments, setting information used in each of the four control modes (for example, repeat function, program memory function, etc.) of the CD player may also be stored in the nonvolatile memory.

〔Effect of the invention〕

As explained in detail above, according to the CD player control device according to the present invention, any song out of a large number of songs on a CD can be played first during timer playback, so that it can meet the various demands of EZA. 1tflj that can meet your needs. Both functions have been added.
Improves practicality.
