Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette tape device used for recording and reproducing video/audio, computer data/programs, etc.

Conventional Structure and Problems Traditionally, cassette tape has become rapidly popular due to its small size, ease of handling, and high performance. For example, video cassettes are widely used for video recording, compact cassettes and ultra-small cassettes are used for audio recording, and cassette tapes of various standards are widely used for recording computer programs and data.

Although cassette tapes are considered to be highly popular due to their low price and high recording density, they also have some problems unique to tapes.

One of them is slow access time due to tape winding speed.

For example, in computer cassette tapes, a section called a directory is sometimes provided at the beginning of the tape to record file names, etc., but if you want to change the execution contents midway through, each time you rewind the tape to the beginning and file the file. After referencing the name, the tape must be fed again to the required position, which causes problems such as a decrease in processing speed.

These are fundamental problems with tape devices, and occur because all necessary information is recorded on the same tape.

In addition, although there is no part equivalent to a directory on ordinary video/audio cassette tapes, the recorded contents can be checked by writing on the label attached to the surface of the cassette tape case or on the attached memo. was. If this is the case,
There were problems with long-term storage and rewriting when used frequently, and it was also difficult to read electronically.

Furthermore, with compact audio cassette tapes, the magnetic tape is exposed through the magnetic head contact window on the side of the case, and there are many problems such as dust and fingerprints that are not desirable for high-density magnetic tape recording.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and by adding simple structural functions to the cassette tape, it greatly improves the functionality, operability, and reliability that the cassette tape originally has. The purpose of the present invention is to provide a cassette tape device that can be used.

Structure of the Invention The present invention is a cassette tape device that includes a magnetic tape and a tape guide running means for stably running the magnetic tape in a cassette tape case, the magnetic tape being directly exposed on the surface of the cassette tape case. In order to prevent this, an opening/closing shutter mechanism is provided between the magnetic tape and the inner surface of the cassette tape case that can slide in the running direction of the magnetic tape, and is fixed to the shutter body of the shutter mechanism. Reno (by some,
The shutter mechanism can be mechanically opened and closed from outside the cassette tape case, and further, recording and reproduction can be performed magnetically or by other means on some of the parts that move in conjunction with the four sliding movements of the opening/closing shutter mechanism. Necessary information is recorded in a portion that can be recorded and reproduced magnetically or by other means in conjunction with the sliding movement of the shutter opening/closing mechanism using an external magnetic head or other recording/reproducing means. This is a cassette tape device that is characterized by a playback scale, and by providing a tape protection shutter mechanism and an additional magnetic or other means capable of recording and playing back a conventional cassette tape, it is possible to improve the original characteristics of the cassette tape. This can significantly improve reliability, functionality, and operability.

The explanatory diagram of the embodiment shows a sectional view of a cassette tape device in an embodiment of the present invention.

1 is a cassette tape housing, 2 is a shutter main body of an open/close type shutter mechanism, and this is a closed loop shape that can be slid along the inside of the cassette tape housing 1 by a guide body 9. 03 is a shutter A part of a lever for mechanically sliding the main body 2 from the outside, 4 a reel hub, 6 a magnetic tape disposed inside the shutter main body 2, 6 for recording and reproducing information on the magnetic tape 6; magnetic head contact window,
Reference numeral 7 denotes a magnetic recording/reproducing portion that uses magnetism as a recording means provided in a portion that moves in conjunction with the opening/closing shutter mechanism, and 8 denotes a magnetic head contact window for recording and reproducing signals in the magnetic recording/reproducing portion 7. It is. And 9 is a mechanism for keeping the shutter closed when the cassette tape is not in use.

The operation of the cassette tape device of this embodiment configured as described above will be described below.

First, normally, when the cassette tape is not in use, the magnetic head contact window 6 of the cassette tape is closed by the shutter body 2. When this cassette tape device is loaded into the cassette deck,
The reel nop 3 is pushed down, the magnetic head contact window 6 opens, and then the magnetic head is inserted and the reel nop 4 is opened.
The necessary signals are recorded by rotating the magnetic tape 6 and driving the magnetic tape 6. When the recording of the necessary signals onto the magnetic tape 6 is completed, the shutter main body 2 is temporarily closed, the magnetic head is inserted through the second magnetic head contact window 8, and the shutter main body 2 is opened and closed again. , Necessary information to the magnetic recording/reproducible portion 7,
For example, information, control signals, etc. related to the contents of the signals recorded on the magnetic tape 6 are recorded.

During reproduction, at the same time as the shutter body 2 opens and closes, the information in the magnetically recorded and reproducible portion 7 is read out, necessary information is displayed,
After setting the control signals, etc., the signals from the magnetic tape 6 are reproduced.

As described above, according to this embodiment, the conventional cassette tape is further provided with an auxiliary magnetic signal recording/reproducing section that also serves as a shutter mechanism for protecting the magnetic tape. This greatly improves the reliability, functionality, and operability of cassette tapes.

In this embodiment, the shutter main body 2 of the opening/closing shutter mechanism has a closed loop configuration along the inside of the cassette tape housing as shown in the figure, but of course it does not have to be a closed loop, and the path of the shutter It goes without saying that you can take another path as well. Furthermore, although the magnetic recording/reproducing portion 7 and the magnetic head contact window 8 are provided on the opposite side of the magnetic head contact window 6 for the magnetic tape 6 inside the cassette tape in the figure, this position is of course not necessarily on the opposite side. There is no need for it to be there, and it can be anywhere as long as it can be magnetically recorded and reproduced. Furthermore, although magnetism is used for the recording/reproducing portion 7 in this embodiment, other means such as optical means may be used as well.

Effects of the Invention The present invention provides a magnetic head contact window of a cassette tape with an opening/closing shutter mechanism that can slide in the tape running direction, thereby preventing the internal magnetic tape from dust, fingerprints, etc. It is protected from external factors, and furthermore, a part that can be recorded and reproduced by magnetic or other means is provided in the part that is linked to the four sliding movements of the opening/closing shutter mechanism, and necessary information is stored in the recording and reproducing part by the opening and closing operation of the shutter. By making it possible to record and play back cassette tapes, the reliability of the cassette tape is increased, and at the same time, functionality and operability are greatly improved, making it possible to realize an excellent cassette tape device.
