By providing a switching means for displaying the set time and remaining operation time of a scan mode in which the images are sequentially reproduced for a predetermined period of time, the configuration is simplified and costs are reduced.

[Conventional technology]

Recently, recording and reproducing apparatuses such as DATs have been commercially available which are equipped with a digital margin display section that numerically represents the margin up to the maximum permissible level of an input signal or an output signal during recording or reproduction. Also, depending on the DTA, if multiple songs are recorded, the first song may be started for a predetermined period of time, for example, 8
Play for seconds, enter fast forward mode (search mode),
Some devices have a scan mode (hereinafter referred to as music scan mode) in which the beginning of the next song is searched for, the music is played again from there for a predetermined time, and the beginnings of the next song are similarly played back for a predetermined time at a time.

[Problem to be solved by the invention]

By the way, there is a desire to display the time in this music scan mode on the panel surface.

Therefore, it is possible to display the time in music scan mode directly on the panel surface, but in this case, it would require more space on the panel surface, the configuration would be complicated and large, and it would be expensive. There are drawbacks such as.

The present invention has been made in view of the above, and it is possible to simplify the configuration, reduce the size, and reduce the cost by using the digital display section of the margin as the time display during the music scan mode. The present invention provides a playback device.

[Means to solve the problem]

The recording and reproducing apparatus according to the present invention is a recording and reproducing apparatus equipped with a margin digital display section that indicates the margin up to the maximum allowable level of an input signal or an output signal during recording or reproduction. The apparatus is provided with a switching means for displaying the set time and remaining operation time of a scan mode in which the beginning of a song is sequentially played for a predetermined period of time.

[Function] In the present invention, the digital display section of the margin displays the music scan setting time in the stop mode, and displays the remaining music scan operation time in the playback mode. This eliminates the need to provide a dedicated music scan time display section, making it possible to simplify the configuration, reduce the size, and reduce costs.

[Embodiment] Hereinafter, a case in which an embodiment of the present invention is applied to a DAT will be described in detail based on FIGS. 1 to 4.

FIG. 1 is a schematic diagram of a DAT panel according to the present invention. In the figure, (1) is a display section, (2) is a tape drive mode switching selection section, and (3) is a music scan button. The tape drive mode switching selection section (2) includes a cassette 2-ray opening button (2aL), a stop button (2b), and a playback button (2aL).
c), recording button (2d), 1 o'clock stop button (2e), recording mute button (2f), fast forward SD (2g) and rewind button (2h) used for fast forwarding (FF) and rewinding the tape (REW). ), an AMS (Automatic Music Scan) fast forward button (2i), and an AMS rewind button (2j). There are various other buttons, but since they are not directly related to this invention, their explanation will be omitted.

The input section (4) including the tape drive mode switching selection section (2), the music scan button (3), etc., and the display section (1) are connected to the CPU (5) as shown in Fig. 2. Further, this CPU (5) is connected to a recording/reproducing circuit section (6) for audio signals and subcode signals and a system drive control section (7).

The recording and reproducing circuit section (6) includes at least an A/D and D/A conversion circuit (6a), an encoder, a decoder (6b), a recording and reproducing amplifier (6c), and a rotating head (6d),
The system drive control section (7) includes at least a reel drive control circuit (7a), a capstan servo circuit (7b), and a rotating drum servo circuit (7C).

Then, the CPU (
5) is operated to control the recording/reproducing circuit section (6) and the system drive control section (7).

FIG. 3 shows the playback state of the display section (1) of the DAT according to the present invention. In the figure, (1a) is the maximum permissible level (O
This is a digital display of the margin that shows the degree of margin up to dB). The digital display area (1a) of this margin is d with rMARGTNJ of the normal margin lit.
Although it is displayed as B display, the music scan button (3)
When is pressed, 'MARGINJ' goes out and the display changes to seconds (S) indicating the operating status of Music Scan. At this time, the music scan display section (1b) lights up to indicate the music scan mode.

Here, the music scan mode can be roughly divided into the following three types.
There are two modes. The first mode is stop mode, and when you press the music button (3) and the play button (2C), the program rewinds and returns to the beginning of the first song in the program. The second mode enters the so-called music scan mode in which the steps are repeated for each image in sequence. In the second mode, press the music button (3) in stop mode and press AMS fast forward 5O (2i) to fast forward from the point where it stopped. and go to the beginning of the next song,
From this point on, you will enter normal music scan mode.

In the third mode, when you press the music button (3) in the stop mode and press the AMS rewind sum (2j), it will rewind from the point where it stopped and go to the beginning of the song, and the beginning of the song will be played for a predetermined time, e.g. It plays for 8 seconds, then rewinds again to play the beginning of the previous song, repeats this operation to return to the beginning of the first song, and after playing that beginning for a predetermined time, enters the stop state.

Next, switching between the margin display and the music scan time display will be explained with reference to FIG.

In step (10), a music scan time of 8 seconds, for example, is automatically initialized in the memory (not shown) in the CPU (5). Margin display is started in step (11), and in step (12) the CPU (5) determines whether or not it is in music scan mode, and if it is not in music scan mode, step (13) is executed.
Then, a margin is displayed on the digital display section (1a) and the process returns to step (12).

In step (12), you have already pressed the music scan button (3).
is pressed and is in the music scan mode, in step (14) the CPU (5) checks whether the stop button (2b) has already been pressed and is in the stop mode or the AMS
It is determined whether or not the button is pressed and the search mode is selected. If the button is pressed and the search mode is selected, the music scan setting time is displayed in step (15) on the digital display (1).
Display in a). Of course, at this time, rMUsIc 5CANJ on the music scan display section (1b) also lights up.

In this state, the music scan setting time can be changed by pressing the fast forward button (2g) and the rewind button 61] (2h). That is, in step (16) the CPU (
In step 5), it is determined whether or not the fast forward button (2g) is pressed, and if it is, in step (17), the music scan setting time is increased, for example, by 1 second, and the step (
Return to 12). On the other hand, in step (16), press the fast forward button (2
g) is not pressed, in step (18) the CPU (
In step 5), it is determined whether or not the rewind button (2h) is pressed, and if it is, in step (19), the music scan setting time is decreased, for example, by 1 second, and then the step (
Return to 12). In addition, in step (1B), press the rewind button (2
If h) is not pressed, the process directly returns to step (12).

If it is not the stop mode or the search mode in step (14), it is determined in step (20) whether or not the playback button (2c) has already been pressed in the CPU (5) and the mode is in the playback mode. Returning to step (12), if the playback mode is selected, the remaining music scan operation time is displayed on the digital display section (1a) in step (21). In step (22), the CPU (5) determines whether or not the playback button (2c) is kept pressed. If it is kept pressed, the process returns to step (21), and if it is not kept pressed, the step In (23), the remaining music scan operation time is subtracted, for example, in 1 second steps according to the music scan operation. In step (24), the CPU (5) determines whether the display on the digital display section (1a) is "0.0 seconds", and if not, returns to step (21) and performs the above-mentioned operation. Repeat until the time reaches "0.0 seconds" and then return to step (12).

In this way, in this embodiment, the digital display section (la) of the margin is used to display the music scan setting time in the stop mode, and this is also displayed using the fast forward button (2g
) and the rewind button (2h).On the other hand, in the playback mode, the remaining music scan operation time is displayed, so the digital display in the margin can also be used to display the music scan operation time. As a result, the space on the panel surface can be saved to that extent, and the structure can be simplified, downsized, and costs can be reduced.

In addition, r PGMNOJ and ``^? ISj etc. are not display parts that are related to the driving system, but 'MARGI' which has little to do with the driving system.
Since the NJ display section is used, the above-mentioned function can be achieved with less missing information.

In addition, the music scan setting time, operation part,
(3) is the music scan button, (4) is the input section, and the remaining time is displayed, so the music (
5) is a CPU, (6) is a recording/reproducing circuit unit, and (7) is capable of time-managing the system scan operation.
This is a drive control section.

(Effects of the Invention) As explained above, the present invention selectively displays the setting time and remaining operation time of the musink scan on the digital display section of the margin, thereby simplifying the configuration, reducing the size, and It is possible to reduce costs and to manage the time of the music operation.Furthermore, since a display section that is not related to the driving system is used, there is less missing information (and the above function can be achieved). Make the most of your efforts.
