DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio device such as an MD or a CD device, and more particularly to a technique for displaying information in such an audio device.

[0002]

2. Description of the Related Art Conventionally, information display in an audio device is typically performed by displaying a type of a medium being output or a medium being output (for example, a liquid crystal display device provided on a front panel of the audio device). This is performed by displaying the title / number of the MD, the title / number of a track such as a song being output, the current time, and the like. In such an acoustic device, the number of characters that can be displayed is often limited to one line in order to reduce its size.

FIG. 4 shows a display state of such a conventional acoustic device.

In the example shown, the number of characters that can be displayed is 16 characters.

[0005] Here, the display area shown is divided into a plurality of areas for each information during normal display.
# 1 indicates a state at the time of normal display. As shown in the figure, in this example, the first three characters are used to indicate the type of the medium being output, and the next seven characters are used. Are used to display the title / number of the medium or track, one character is opened, and the last five characters are used to represent the current time.

Here, since an area for a fixed number of characters is assigned to each piece of information as described above, if the number of characters of the information is larger than the number of characters of the corresponding area, all of the information cannot be displayed. For example, in the example of FIG.
Seven characters are assigned to display the title / number of the medium or track. However, since the number of characters of the title / number of the medium or track is more than seven characters, only the first seven characters can be displayed.

Therefore, such audio devices often support scroll display so that all characters of information can be confirmed.

[0008] # 2 to # 17 show such a scroll display.

In this example, when the audio device receives a scroll display instruction from the user, the following series of processing is automatically performed.

That is, first, the display of # 1 is switched to the display of # 2. In the display of # 2, an area for 13 characters from the fourth character to the last sixteenth character is allocated to the display of the title / number of the medium or track, and the first area of the title / number of the medium or track is assigned to this area To the thirteenth character. Next, following the display of # 2, the audio device performs scrolling to display the 13 characters of the title / number of the medium or track while sequentially shifting one character at a time as shown in # 3 to # 17. . That is, in # 2, 13 characters from the first character to the thirteenth character of the title / number of the medium or the track are displayed.
3 displays 13 characters from the 2nd to 14th character, and # 4 displays 13 characters from the 3rd to 15th character, such as displaying the character string of the title / number of the medium or track. The part to be shifted is shifted one character at a time.
When the last character of the character string of the medium / track title / number reaches the first area of the area allocated to the display of the medium / track title / number (# 17), the scroll display is terminated, and The display is returned to the normal display of # 1.

[0011]

According to the scroll display according to the prior art, there are cases where the scroll speed is too fast for some people to confirm the contents. Conversely, if the scroll speed is reduced, some people may feel inconvenience. Further, according to the conventional scroll display technology, when some characters are missed during scroll display, scroll display must be performed from the beginning to confirm this. .

SUMMARY OF THE INVENTION It is an object of the present invention to realize a convenient scroll display which can flexibly respond to each user's request.

[0013]

In order to achieve the above object,
The present invention reproduces an audio signal of each track recorded on a recording medium, and displays a character string portion, which is information on a storage medium or a track being reproduced, in an area where a fixed number of characters can be displayed on a display device.

The microcomputer 1 performs the following processes according to the program stored in the memory 2.

In such a configuration, one of the acoustic signals reproduced by the driver 4 from the MD or CD and the acoustic signals received and demodulated by the receiver 5 by receiving the FM / AM radio waves are used by the microcomputer 1 using the select switch 11. The signal is selected and sent to the output unit 6 according to the control performed by the user, and is appropriately amplified and then output from the speaker 7. The display on the display device 3 is controlled by the microcomputer 1.

FIG. 2 shows a processing procedure of processing performed by the microcomputer 1 to control the display on the display device 3.

This process is started and executed periodically. The initial state of the display is the normal display shown in FIG. 3 # 1. In the normal display shown in FIG.
Type of medium for which characters are being output (MD / CD / FM / A
M), the next seven characters are used to display the title / number of the medium or track, one character is opened, and the last five characters are used to represent the current time. Do. In the present embodiment, a manual mode and an auto mode are provided as scroll modes, and two states of manual permission and prohibition are provided.
Here, it is assumed that the initial state of the scroll mode is the auto mode, and the state is the manual inhibition state. These are (auto mode, manual prohibited), (manual mode,
Three combinations of (manual prohibition) and (manual mode, manual permission) are possible. Then, in the manual prohibition state, the display is a normal display, and when (manual mode, manual permission), it indicates a state in which a manual scroll operation by the user is accepted.

By the way, (auto mode, manual prohibition)
Or (manual mode, manual prohibited) state,
That is, it is assumed that the automatic mode is instructed by the scroll mode changeover switch 8 in the normal display state. In this case, first, in step 200, "
It is determined that the mode is the manual mode and the manual permission state is not set, and it is detected in step 201 that the scroll mode changeover switch 8 is turned on, and the mode instructed in step 204 is the auto mode. In this case, the scroll mode is switched to the auto mode in step 205, the current display mode (normal display in this case) is stored, and step 2 is performed.
In step 06, the display of the display device 3 is changed from # 2 to # 17 in FIG. 3 in the order in which the display is changed at regular intervals, and in step 207, the state is manually prohibited. Is returned to the stored display mode (normal display). Then, the process ends.

On the other hand, let us consider a case where the automatic scrolling is instructed by the scroll mode changeover switch 8 in the state of (manual mode, manual permission), that is, in the state of accepting the manual scrolling operation. In this case, first, in step 200, it is determined that the mode is the manual mode and the manual is allowed, so that the process proceeds to the manual scrolling process from step 213.

Next, (auto mode, manual prohibition)
Or (manual mode, manual prohibited) state,
That is, it is assumed that the manual mode is designated by the scroll mode switch 8 in the normal display state. In this case, first, step 200
In step 201, it is determined that the scroll mode changeover switch 8 has been turned on, and the mode designated in step 204 is the manual mode. It is determined that there is. In this case, in step 208, the manual mode is set, and in step 209, the state is set to the manual permission state, and the state transits to a state in which a manual scroll operation is accepted. And
At step 210, the current display mode (in this case, the normal display) is stored, and at step 211, the display area of the display and the title / number of the medium and track of FIG. 3 # 2 is expanded to 13 characters. Change to something. Then, the process ends.

On the other hand, consider a case where manual scroll is instructed by the scroll mode changeover switch 8 in the state of (manual mode, manual permission), that is, in a state of accepting a manual scroll operation. In this case, first, in step 200, it is determined that the mode is the manual mode and the manual is permitted, so that the process proceeds to the manual scrolling process from step 213.

As a result, the operation of the manual scroll up switch 9 and the manual scroll down switch 10 is ignored in the present processing started in the state of (auto mode, manual prohibition) or (manual mode, manual prohibition). In the present process started in the state of (manual mode, manual permission), the operation of the scroll mode changeover switch 8 is ignored.

Now, in the state of (manual mode, manual permission), that is, in the state of (auto mode, manual prohibition) or (manual mode, manual prohibition), the manual mode is designated by the scroll mode changeover switch 8, and step 208 , 209 (manual mode, manual permission) are set, the following processing is performed.

First, in step 200, since it is determined that the mode is the manual mode and the manual is permitted, the process proceeds to the manual scrolling process from step 213. Then, in step 213, the manual scroll-up switch 9 is kept for a certain period of time after the manual permission is set or the previous operation of the manual scroll-up switch 9 or the manual scroll-down switch 10 is performed.
Alternatively, it is checked whether or not the manual scroll down switch 10 has been operated. If not, the manual prohibition is set in step 214, and the display device 3 is changed to the display form (normal display) stored in step 210.
Return the display of.

On the other hand, a manual scroll up switch 9 or a manual scroll down switch 10
If any operation has been performed, one of the following processes is performed according to the content of the operation.

That is, if the manual scroll-up switch 9 has been turned on since the previous scroll-up (step 216), the previous one-character,
It is determined whether a predetermined period has elapsed after scrolling (scrolling up) the display in a direction in which the character is advanced (step 217). If it has elapsed, the display is scrolled in a direction in which the character is advanced by one character (step 217). Step 218).
That is, the display of # 3 to # 17 in FIG. 3 is advanced by one in this order. For example, if the display of # 10 is currently being performed, the display is changed to the display of # 11. Then, the process ends. However, if the display of # 17 has already been performed, no further progress is made.

Conversely, if the manual scroll-down switch 10 has been turned on since the previous scroll-down (step 219), the display is scrolled in the direction of returning one character or character the previous time (scroll-down). Then, it is determined whether or not a predetermined period has elapsed (step 220). If the predetermined period has elapsed, the display is scrolled in the direction of returning one character or character (step 22).
1). That is, the display of # 2 to # 17 in FIG. 3 is returned by one in the reverse order. For example, if the display of # 10 is being performed, the display is changed to the display of # 9. Then, the process ends. However, if the display of # 2 has already been performed, no further return is made.

In other cases, if the manual scroll-up switch 9 has changed from off to on (step 222), the display is scrolled in the direction of moving forward one character, as in step 218 (step 222). Step 223).

Also, a manual down-up switch 1
If 0 changes from off to on (step 2
24) As in step 221, scroll the display back in the direction of returning one character or character (step 22).
5).

As described above, one embodiment of the present invention has been described.

The mode is designated by the scroll mode changeover switch 8, for example, if the ON time is shorter than a predetermined time, an auto mode instruction is given, and if the ON time is longer than a predetermined time, the manual mode instruction is given. It may be made to depend on the time which is. Of course, a switch having a contact for each may be provided.
