Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cassette tape recorder device, and particularly to an improvement in the function of randomly accessing contents recorded on a cassette tape.

[Technical background of the invention]

Nowadays, tape recorders are used not only to locate the beginning of the content recorded on the tape (for example, a song), but also to locate the desired part of the same song by the user. Products equipped with a so-called random access function, such as high-speed selection and automatic playback, are emerging. This random access function provides a data track on which information data such as a song is recorded on the tape, and an address track on which address data indicating continuous elapsed time from the beginning of the tape to the end of the tape is recorded. This is realized by high-speed tape playback until the data matches the address data preset by the user.

In this case, data called a directory is recorded in an address track at the beginning or end of the tape so that the user can easily set address data for a desired tape position. The contents of this directory include, for example, the song numbers of a plurality of songs recorded on the tape and address data indicating the tape position where the confession is recorded. When playing back a tape, first, the data in the directory is played back and the contents are stored in the memory of the tape recorder device, and when the user specifies the desired track number, the data corresponding to that track number is played back. The address data is read out from the memory.

[Problems with background technology]

However, conventional tape recorder devices equipped with the above-mentioned random access function have the problem that the data in the directory section must be read each time the tape is changed, making handling inconvenient. There is.

In addition, if the tape is in the middle at 1 o'clock, it is necessary to rewind or fast forward to the beginning or end of the tape where the directory section is located, making it even more inconvenient to handle the tape. It is something.

Particularly recently, it has been considered to convert the tapes into cassettes, but the problems mentioned above greatly reduce the advantage of making them easier to handle. There is something that will damage it.

[Purpose of the invention]

This invention was made in consideration of the above circumstances, and there is no need to read the data in the directory section again every time the tape is replaced, by converting the tape into a cassette. without sacrificing the advantage of convenient handling.
Another object of the present invention is to provide an extremely good cassette tape recorder device that can be handled more conveniently.

Here, an identification code setting part 13 is provided on the side part 121, which is the back surface of the cassette 12, as shown in FIG. 2(,). This identification code setting section 13 has a plurality of (
In the illustrated case, 10 claws 73 & - 13j are arranged in a row, and as shown in FIG. By taking the tag, you can set an identification code for that tag cassette. That is, if the part with claws is set to logic "1" and the part without claws is set to logic "0", then in the case of FIG. 2(b), the identification code r is roolol.
ollo J. By doing this, it is possible to obtain 210 identification codes, which means that the controller can also set a unique identification code for each of the 210 tape cassettes. .

The tape cassette is installed in the tape cassette storage section of the main body of the cassette tape recorder, and
The identification code is automatically read by an identification code reading unit 14 as shown in FIG. This identification need reading υ part 14, the above winter melon 13a~
13j, pushbutton type switches 14a to 14Z
4j are arranged in a row, and the claws 13a~
The identification code is electrically read when the switches 14a to 14J are pressed or not, depending on the presence or absence of the switch 13j.

FIG. 4 shows the identification data read in the above manner from the circuit system in the main body of the cassette tape recorder, and
This figure shows a processing circuit system for directory data and address data obtained by reproducing the address tosic of Chifil. Note that the recording and reproducing circuit system for the data tracks of the tape 11 is the same as the conventional one, so a description thereof will be omitted.

That is, in FIG. 4, numeral 15 is a head for reproducing the address track of the tape 1. This head 1
The reproduced data outputted from 5 is supplied to a directory separation circuit 18 and an address separation circuit 19 via a synchronization circuit 16 and an error correction circuit 17, respectively. and,
The above directory separation circuit 18 and address separation circuit 1
Each output of 9 is supplied to a human power port 20, respectively.

This input port 20 has the identification code reading part 1.
The output from 4 is also provided.

The output of the input port 20 is the Nono line 2.
1. On this pass line 21, there is a microprocessor 22. Read/write storage device (hereinafter referred to as RAM)
23. Read-only storage device # (hereinafter referred to as ROM) 241 display section 25 output port 26. The input/output port 28 of the key operation unit 27 and the output port 30 of the third unit 29 are connected.

Here, the RAM 23 stores identification codes and directory data in correspondence with each other, and as described above, the identification codes of 210 (= 1024) tape cassettes r 0000000000 J to r 1llll'
1llllll J and the directory data "data (0)" to [f-ta (1023) J of the tape 11 indicated by its identification code are made to correspond as shown in the following table, so that they can all be stored. .

The ROM 24 also includes a microprocessor 22.
A program to control the operation of the machine is stored.

Furthermore, the tape drive mechanism 29 is a mechanism that moves the tape 11 into a predetermined running state and into a predetermined running state, and is a so-called logic-based mechanism in which the mechanism is operated by an electrical command signal.

Further, the key operation unit 27 performs operations on the tape drive mechanism 29 to bring the tape 1 into a predetermined running state and a running stopped state, and also performs operations such as setting a track number for random access. It is something to do.

Furthermore, the display section 25 displays the elapsed travel time based on, for example, address data obtained during tape playback.The IJ data includes the title of the song recorded on tape 1, etc. If such information is included, it can also be displayed.

In the above configuration, referring to the flowchart shown in FIG. 5 and the functional block diagram shown in FIG. 6,
Let's explain its operation. First, when the tape cassette is loaded into the tape cassette storage section in the Stella f ST, the identification code of the loaded tape cassette is read out by the identification code reading section 14 in step ST2. Then, this read identification code is transmitted to the input port 20 and the pass line 2 in step ST under the control of the microprocessor 22.
register 22a in microprocessor 22 via
is temporarily stored.

Next, the microprocessor 22 executes R in step ST4.
The identification codes stored in the AM 23 are sequentially read out (scanless), and the register 22m is read out in step ST.
The identification code stored in RA! The identification code read from i1123 is sequentially compared.

Here, if the above-mentioned tape cassette is inserted into the tape cassette storage section of this cassette tape recorder main body for the first time, the identification code of this tape cassette cannot be stored in the RAM 23. As a matter of course, the result of the comparison in step 8T5 is NO as there is no match, that is, Stella f ST5.

Then, in step 8T6, the microprocessor 22 generates a command signal to cause the tape drive mechanism 29 to run at high speed through the pass line 21 and the output port 30, and causes the tape to run at the beginning or end of the tape 1. Search the directory section. Next, the microprocessor 22 processes the bus fin 2 and the output port 3 at step ST.
0, a command signal is generated to the tape drive mechanism 29 to put it into a tape playback state, and the data in the searched directory section is read out. In this case, the data in the directory section is stored in the head 15, the synchronization circuit 16. Error correction circuit 17
．． The data is stored in the RAM 2 s ff through the directory separation circuit 1B, the input port 20 and the pass line 21.

Also, at this time, the register 22 of the microprocessor 22
The identification code stored in the RAM 2B is also stored in the RAM 23 via the pass line 21, and the new tape cassette identification code and directory data are stored in the RAM 2B.
This is what is stored in the memory.

The identification code and directory data are stored in RAM.
23, the cassette tape recorder main body enters a standby state (Stella fST8) in which it waits for an operation command from the key operation section 22.

As for the tape cassette whose identification code and directory data have been once stored in RAM J3 as described above, even if the tape cassette is changed, the comparison result by Stella f Sr1 will be YES in step ST5 if they match.
becomes. At this time, the tape's contents) IJ
Since the data has already been stored in the RAM 23, step ST6. It is possible to directly shift to the operation standby state (step 5T8) without going through s'r.

Here, in the operation standby state as described above, for example, if you do not want to select the third and fifth songs on Cijino 1, press the key operation section 2.
Assume that the operators corresponding to song numbers "3" and "5" of 7 are operated. Then, the operation data is taken into the microprocessor 22 via the input/output port 28 and the pass line 21. The microprocessor 22 has a register 22a.
The address data corresponding to track numbers "3" and "5" are read out from among the directory data corresponding to the identification code of the tape cassette currently installed in the tape cassette, and the tape drive mechanism 29 is read out. Puts the tape into high-speed playback mode. And the microprocessor 22
is head 15. Synchronous circuit 16. Error correction circuit 17, address separation circuit 19. Input port 20 and pass line 2
The address data obtained through 1 is the song number "3" above.
When the address data matches the address data corresponding to , the tape drive machine 29 is put into the playback state, and the third song is accessed here.

When the third song ends, the microprocessor 22 causes the tape to be played back at high speed again, and when the address data of the address track of CH f11 matches the address data corresponding to the song number "5", the microprocessor 22 causes the tape to be played back. The fifth song is accessed.

Furthermore, if the directory section contains data such as the title of the song recorded on tape 1, when the key operation section 27 is operated to display the song title, the microprocessor 22
reads the data corresponding to the song title from the directory data recorded in the RAM 23, and reads the data corresponding to the song title from the directory data recorded in the RAM 23,
The display unit 25 is made to enter water through the output port 26 and the output port 26.

Therefore, according to the configuration of the above embodiment, the directory data of a plurality of tapes is stored in the RAM 23 together with the identification code attached to the cassette, and when the tape cassette is loaded, the tape is Since the tape is made to correspond to the directory data, there is no need to read the directory data again every time the chief cassette is changed, and handling of the tape becomes extremely convenient. In particular, since the identification code is attached to the cassette 12, directory data can be obtained simply by loading the tape cassette into the tape cassette storage area, regardless of the position of the tape 11. Random access can be performed, which also makes handling convenient.

Here, in Embodiment 10 above, the case where address data and directory data are written in one address track was explained, but in this case, a track for address data and a track for directory data are provided separately. It is of course possible to do so. Further, the directory section may be provided at either the beginning or the end of the tape; for example, it may be provided at both. Furthermore, it goes without saying that the identification data setting section 13 attached to the cassette 12 is not limited to the side section 12f that is the back surface of the cassette 12, but may be, for example, a flat section or both side sections. In addition, the identification code reading section 1
4 is not limited to the means shown in FIG. 3; for example, the identification code may be read as serial data by relatively moving one switch and the identification code setting section of the cassette. good.

Furthermore, the address track and data track are reproduced by one head, and the directory data and address data are reproduced in the following Ig processing stage.

Of course, the data may be classified into information data, etc.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

〔Effect of the invention〕

Therefore, as described in detail above, according to the present invention, for Qi 1 who has once read the data in the directory IJ section, there is no need to read the data in the directory section again every time the tape is changed, and the tape can be converted into a cassette. As a result, it is possible to provide an extremely attractive cassette tape recorder device that can be even more convenient to handle without sacrificing the advantage that it can be handled more conveniently.
