Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical digital audio player, and particularly provides a digital audio player 11+' that is multifunctional and equipped with a compact display.

In general, optical digital audio players (hereinafter referred to as players) utilize a non-contact playback method, which is their most significant feature, and can immediately start playback from any position on a disc. This is called random access and the user can move to the desired position of random access (
By sequentially registering and storing commands (hereinafter referred to as commands) in the player, the commands are automatically played in the order of the commands.

For example, the third, first, and fifth songs are 1 minute and 12 seconds long.

If you register a command like 7th song 3 minutes 16 seconds,
The player plays the third song from the beginning to the end, and then plays the first song from the beginning to the end. After that, the player plays from the 1 minute 12 second position of the 6th song to the last position of the 6th song, and finally plays from the 711th position 3 minutes 16 seconds to the end of the 7th song.

In the above case, each command is a 2-digit, 9-minute, 2-digit song number.

It has a maximum of 6 digits, including 2 digits for seconds, and a 6-digit display is required to create commands. Also, in the above example, there were four steps (songs), so the number of commands (steps)
is 4, and in order to display all of the registered commands, a large-scale display device as shown in FIG. 1 is required.

In response, a display device has been proposed that is extremely compact and has multiple functions, including a portion that not only displays the above-mentioned commands but also displays the current performance position in an analog manner.

In this display, 1 is the pickup position, 2 is the end position of the area where music information is recorded, 3 is the start position of each picture recorded on the disc (optical digital audio disc), and 4 is the position of the beginning of each picture recorded on the disc (optical digital audio disc). 6 is a display section that shows each command (target position of random access) created by the user of the player, and 6 also displays the time of 9 minutes and 9 seconds of the song at the playing position during performance, and This is a 6-digit display section that displays the command when the command is being set and during random access during command execution.

In the display shown in FIG. 2 above, when the user creates a command using the key switch shown in the figure (7), it is displayed on the display section 6. When the user completes creating a one-step command and registers it in the player, the command is displayed on the display section 6. , the display on the display section 6 is reset, and the position corresponding to the command assigned to the receiver is displayed as a bar graph on the display section 4.Therefore, compared to the display of this display Q71 in FIG. It has the advantage of being small and inexpensive.

However, the display shown in FIG. 2 has a drawback, compared to the display shown in FIG. 1, that it is inconvenient because the order in which the commands are registered cannot be determined. Furthermore, the display shown in FIG. 2 displays registered commands with the accuracy of the bar graph on the display section 4, and therefore cannot accurately display commands once accepted. In other words, the command is to input 6 digits of 1 minute and 9 seconds of the song on the display section 5, but since the display section 4 displays in 1-minute increments, it is necessary to enter the registered command in 1 minute increments. The drawback was that it was not possible to know exactly whether it was a second or not.

The present invention solves the above-mentioned drawbacks of the prior art and provides an optical digital audio player equipped with a six-display display so that set commands can be confirmed correctly.

Therefore, the present invention is equipped with a function to arbitrarily read commands once registered in the player and display them on the display section used when setting the commands, so that the user can accurately know the order in which the commands are registered and their contents. It becomes possible.

FIG. 3 shows the configuration of essential parts in an embodiment of the present invention.

10 is an arithmetic processing unit; 11 is a storage unit (memory) for storing commands; 12 is an operation unit that is provided with various key switches and can send output to the arithmetic processing unit 10; It is a driven display.

The player user creates a command using the numbers and processing command key switches shown at 12a. At this time, the information inputted by the key switch 12a is processed by the arithmetic processing section 1 and displayed on the six-digit display section 13a of the display 13. This display allows the user to obtain information about the command being created.

When one step of command creation is completed and the user registers the command in the player, the user only needs to perform key operations for the necessary processing commands. For example, the Ent of the key switch 12a
A command is registered in the player by pressing a key. That is, the arithmetic processing section 1 stores the created command in the storage section 2, and at the same time displays the position corresponding to the command as a bar graph on the display section 13b. This allows the user to know that the command of the first step has been registered. Similarly, as a second step, commands are created for each step in sequence, such as the command for the second song to be played, and are registered each time.

Next, when the user wants to know the exact contents of the command once registered, the user can display the command once registered on the display section 13a.
Key operations necessary to activate the function displayed on the screen (hereinafter referred to as recall), such as the recall key 12 on the operation panel.
Press b.

In this recall operation, by pressing the quick recall key 12b many times, commands can be displayed one by one on the display section 13a in the order in which they were registered each time the key is pressed.

Next, to display any command, for example the number 2
By pressing the key and the recall key in succession,
The second registered command can be displayed on the display section 13a. It may also be convenient to configure the system so that if the recall key 12b is pressed continuously for several seconds or more, the commands are displayed for two seconds each in the order in which they were registered, even if the child is subsequently released.

When a recall process is input to the arithmetic processing section 1 by pressing the recall key 12b, a command to be displayed is read out from the storage section, and the display 13 is driven to display it on the display section 13a. Further, at this time, if the bar display on the display section 13b corresponding to the command being displayed on the display section 13a is made to blink, the display becomes easier and more convenient.

As described above, according to the present invention, the information indicating an arbitrary position being created by the key switch of the operation unit is numerically displayed on the first display unit, and the position information is stored by operating the key switch that instructs storage. At the same time, the temporal position is displayed as a bar graph on the second display section, this is sequentially repeated and stored for a large number of position information, and by operating a key switch to call up the stored position information, a large number of the position information is displayed. Since it is configured to display numerical values on the first display section for statuses that are sequentially or commanded, when confirming position information, it is necessary to display the same numerical values as at the time of creation. We can provide an excellent optical digital audio player that is easy to use and can fully utilize the optical random access function. be.
