Description

DETAILED DESCRIPTION OF THE INVENTION The present invention reads programs or data information recorded on a recording medium such as a cassette or a magnetic card with an index, heading, catalog, file name, or index (hereinafter referred to as an index). In particular, the present invention relates to an information retrieval method for a recording medium that is capable of audibly announcing the contents of an index of program or data information.

Generally, when recording a program or data information on a recording medium such as a cassette or a magnetic card, if an index is added to the beginning of the recording, then when reading the program or data information, just specifying the index will automatically read the program or data information. This is extremely convenient as it allows you to search and read out the information.

In particular, an object of the present invention is to enable such a device to search for programs or data information recorded with an index by specifying the index when reading the program or data information recorded with an index. , the contents of the index can be announced by voice before reading the information of the index.

Another purpose is to determine whether or not the contents of the index have been read correctly, and if they have been read correctly, for example, audible notification of information indicating a signal of completion, and if not, information indicating a signal of an error. This is to make a voice announcement.

Still another purpose is to provide an audio notification that recording has been completed, and to provide an audio notification of the recorded index contents in the cassettes, mug cards, etc. in which they are recorded.

In this way, when a desired index is searched during loading, the contents of the index are announced audibly, and when loading or recording is completed, the contents of the index and a signal of completion are audibly announced. Even if someone is not present at the time, the start and end of information reading can be immediately known, and if the cassette, mug card, etc. in which the information is recorded, only the contents of the index are announced audibly. , it is extremely easy to visually confirm what kind of index contents are stored on the recording medium.

The information retrieval device of the present invention has been made in view of the above points, and one embodiment thereof will be described in detail below with reference to the drawings.

FIG. 1 is a schematic system diagram showing the configuration of an information retrieval system according to an embodiment of the present invention.

In the figure, numeral 1 is an electronic desktop calculator capable of outputting audio, and numeral 2 is a tape recorder capable of loading recording media such as cassettes.

The above-mentioned computer 1 is, for example, of a program storage format, and can record program contents and data contents to a tape recorder 2, or conversely read the contents recorded on the tape recorder 2 and store the program area and data inside the computer. Can be stored in a region.

Reference numeral 3 denotes a signal line that electrically connects the computer 1 and the tape recorder 2, that is, a connector.

The specific configuration of the computer 1 is shown in more detail in the block diagram of FIG.

In Figure 2, 4 is the central processing unit (CPU), 5 is the central processing unit (CPU),
is a voice output control circuit (VOC), 6 is a memory consisting of read-only memory (ROM) and random access memory (RAM), and 7 is an I/O port that serves as an interface between the CPU 4 and the key input section 8. is doing. 9 is a display memory and a display driver, and 10 is a display body. 11 is a modulation unit (MOD) that modulates (converts) the output signal of the CPU into a recording signal for recording on a cassette, and 12 is a demodulation unit that decodes the signal reproduced from the cassette into a format that can be read by the CPU 4. DEM).

The program or data information is stored in six random access memories (RAM). Here, the case where the contents of the RAM memory 6 are recorded onto a cassette will be explained.

(RAM contents → cassette) First, the key input section 8 is used to specify the command to be stored, the contents of the index, and the program or data.

At this time, the CPU 4 transfers the index contents to the cassette, and then transfers the designated program or data to the cassette. Transfer is performed by sending necessary signals from the CPU 4 to the modulation unit (MOD) 11. When the recording is completed, the CPU 4 sequentially sends the index contents and information representing a signal of completion to the audio output control circuit (VOC) 5 to indicate that the transfer has been completed. The VOC 5 outputs audio according to the information sent from the CPU 4, and in this case, outputs audio indicating that the recording of the contents of the index has been completed.

Next, a case will be described in which a desired program or data recorded on a cassette is loaded into the RAM 6.

(Contents of cassette → RAM) First, the instruction to be loaded, the index of its program or data, and the address of the memory to be stored are specified using the key input section 8.

The CPU 4 searches until the specified index contents are obtained from the cassette via the demodulator 12, and when the contents are searched, the contents of the index are announced by voice. Therefore, information indicating the index contents and a signal to start loading is sequentially sent to the audio output control circuit 5.

After that, the contents demodulated from the cassette are stored in the designated memory. When the loading is completed, the contents of the index and information indicating the completion signal are sequentially transmitted to the audio output control circuit (VOC) 5.
send to The VOC 5 gives a voice notification that the loading of the index contents has been completed. If a reading error occurs during loading, the index contents and information on the loading error may be sequentially sent to the VOC 5 in order to notify the loading error audibly. Also, if different index contents are found while searching for a specified index, if that index is also announced audibly, it will be possible to know what kind of index contents are stored in that cassette, mug card, etc. I can do it.

In the above embodiment, a case was described in which a cassette was used as the recording medium, but when loading a mag card, if a specified index is searched, the loading is completed while the contents of the index are being announced audibly. There is a risk of it being damaged.

In such a case, the contents of the index may be voiced as a signal of completion only after the loading is completed.

FIG. 3 is a diagram showing an example of the recording format of a program or data recorded on a cassette, where a is an example of the code and b is an example of the displayed content. The ABCs between ▼ and ▼ are the index contents (file name, etc.), and are the 12 characters next to the second ▼...
The content up to ENDCR is the program or data content.

Note that the number 50 at the beginning of Figure a indicates the beginning of the program.

For example, when recording program content,
REC □▼ □A □B □C □▼ If you enter CR, the contents from the beginning of the program to END CR will be recorded. Therefore, the CPU 4 sends the modulation unit MOD11 a
If you transfer the code shown in the figure and confirm that the code 55 5D continues, it means that the recording has ended. Send in order. When VOC5 receives the first code “O” from CPU4, it changes the S ₀ signal to “0”.
and output the voice “O”, and when the output is finished, the VOC
5 sets the S ₁ signal to "1" and requests the next audio information from the CPU 4, so the CPU 4 judges this S ₀ signal and sends the next "wa" code, and in the same way, "C" send to Note that the VOC circuit Si outputs the words corresponding to the code of the signal as a voice, and after the output is finished, outputs the end signal _S0 .

Next, in the case of loading, the case where the program with the above-mentioned index contents ABC is read into the RAM 6 will be explained.

First, use the key input section 8 to LOAD □▼ □A □B
Key in □C □▼ CR.

The demodulated signal RX from the cassette includes content R data for one code and a signal RS indicating that the content for one code has been demodulated. When the RS signal is "1", the R data is one code. The information for the RS signal is demodulated, and after the CPU 4 judges the RS signal, the RS signal is
shall be "0". Therefore, CPU4 is
Keep the RS signal at "1". and
When the RS signal becomes "1", the CPU 4 reads the R data and first determines whether or not this R data has a code of 50 in order to find the beginning of the recording. If not, the R data becomes a code of 50. keep it until. Then, when the number reaches 50, read the next R data in order and judge whether it matches the code of ▼ABC▼. If it does not match, the R data is a code in order to search for the next recorded index content. If it is found again, it is determined whether the R data is demodulated in order as ▼ABC▼, and if not, this is repeated until they match. If they match, first enter the “S” code to output start ABC and voice.
Send to VOC5. At this time, the VOC 5 outputs the sound "su". While this VOC5 is outputting audio,
The CPU 4 determines whether the RS signal is "1" or the _S0 signal is "1", and if the RS signal is "1", it writes the R data into the memory, and if the _S0 signal is "1", it writes the R data to the memory. Send the next “ta” code to VOC5. Then start ABC and all codes VOC5
, the CPU 4 judges only the RS signal. On the other hand, if the R data is demodulated successively for END and CR, only the _S0 signal is determined. and RS, S ₀
When it is no longer necessary to judge both signals,
The CPU 4 performs almost the same processing as the above-mentioned Owari Rokuon ABC in order to output the Owari code ABC and audio.

As explained above, according to the information retrieval device for a recording medium of the present invention, since the index contents of the indexed program or data information are announced by voice, it is extremely easy to search and confirm the index contents. Further, since signals for starting and ending recording/reading, signals for loading errors, etc. are also audibly announced, the process of recording/reading operations can be quickly confirmed through the auditory sense, which is extremely convenient.
