Abstract

PROBLEM TO BE SOLVED: To easily display a music number by detecting intermusic space from a reproducing music signal by an intermusic space detector, counting this detected signal by a counter, displaying this counted value by a display device and resetting this by a resetting device. SOLUTION: Wen a start key 8 is pressed, the counted value of a counter 6 is reset to '0' to determinate whether a current reproducing position is intermusic space or not. If the reproducing position is not intermusic space as a result of determination, processing for pressing the start key 8 is performed and if the position is determined to be intermusic space, the counted value of the counter 6 is incremented only by 1 and then the process is returned to the processing of the start key 8. The resetting of this counted value is performed by pressing the start key 8 and the counted value of the counter 6 is reset by loading a tape. Also, the starting end of the tape is reached by rewinding the tape, a change to a reproducing operation is detected and then the counted value of the counter 6 is reset. Thus, the usability of a user is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette deck device, and more particularly to a cassette deck device capable of displaying a music number recorded on a tape with a simple structure.

[0002]

2. Description of the Related Art In a CD device for reproducing a compact disc (CD) and an MD device for reproducing a mini disc (MD), music piece number information of music recorded on the basis of information recorded on the disc is simple. You can know
Since it can be displayed on the display, the usability for the user is excellent.

On the other hand, in the cassette deck device, since the tape does not record information such as the music number of a disc, it is impossible to immediately obtain the music number information from the information reproduced from the tape. However, nowadays when the disc reproducing apparatus is generalized, a user's desire to know the song number is generated even when reproducing by a cassette deck.

[0004]

In order to meet this demand in a cassette deck device, there is a method in which the total length of the tape is input in advance and the current position is obtained by a time counter from the speed difference between the winding start and the winding end of the tape. It's possible, but I can't know how many songs are currently playing.

Therefore, the object of the present invention is to provide a simple structure,
An object is to provide a cassette deck device capable of displaying music numbers.

[0006]

In order to solve the above-mentioned problems, a cassette deck device according to the present invention detects a music interval from a reproduced music signal in a reproducing state and outputs a detection signal, and a music interval detecting means. It comprises counter means for counting the detection signals from the interval detecting means, display means for displaying the count value of the counter means, and reset means for resetting the count value of the counter means.

Here, the inter-track detection means can be means for detecting a pause in which the reproduced music signal does not exist based on the level information of the reproduced music signal, and
The reset means may be a key means, a means for detecting the loading of the tape, or a means for detecting the start of reproduction when the tape rewinding operation is completed.

1 is a schematic block diagram of a cassette deck device according to an embodiment of the present invention. The signal read from the tape via the magnetic head of the cassette tape unit 1 is subjected to reproduction processing by the reproduction unit 2, the obtained reproduction audio signal is amplified by the amplifier 3, and reproduction sound is output from the speaker 4. It The reproduced audio signal from the reproducing unit 2 is input to the inter-track detecting unit 5.

The inter-track detection section 5 receives the reproduced audio signal, detects a pause occurring between the music based on the reproduced audio signal level, and generates a detection signal for each detection. The counter 6 is reset by the reset signal, counts the number of times the detection signal from the inter-track detection unit 5 is generated, and displays the count value on the display 7.

The reset signal sets a count value corresponding to a reference position for counting music numbers to a zero value. For example, the reset signal can be generated by pressing the start key 8. Here, when the start key 8 is pressed, the count value of the counter 6 is set to "0" when the reproduction tape position is between songs, and the count value is set to "1" when the song is in the middle of a song. ), The count value is incremented by one.

The operation of this embodiment will be described with reference to the flow chart shown in FIG. 2. First, it is determined whether or not the start key 2 has been pressed (step S1). The count value is reset to "0" (step S2), and it is determined whether or not the current reproduction position is between songs (step S3). If it is determined in step S1 that the start key 7 is not pressed, the process directly proceeds to step S3. Step S
If it is determined in step 3 that it is not between songs, step S1
Returning to the processing of step S3, if it is determined that there is an interval between songs, the count value of the counter 5 is incremented by 1 (step S4), and the processing returns to step S1.

In the above description of the embodiment, the counter 6 is used.
The count value is reset by pressing the start key 8, but the count value of the counter 6 can be reset by detecting that the tape has been loaded. In addition, the count value of the counter 6 can be reset by detecting that the tape has reached the start end by the rewinding operation of the tape and has switched to the reproducing operation, and a special start key is not required.

In the case of a cassette deck, it is not possible to know what the number of the currently playing song is like that of a CD player or an MD player, and if the player wants to play it in the car, it does not play it all the time. There are many cases in which it is lost. Therefore,
In almost all cases, the same display as the song number can be displayed by simply pressing the start key at the beginning of winding the tape.

[0014]

As described above, according to the cassette deck device of the present invention, it is possible to obtain the same music number information as the CD reproducing device and the MD reproducing device with a very simple structure and display it on the display. , The user usability is improved.
