Abstract

PURPOSE:To increase the frequency band of a tape cassette by driving a loading arm to draw a magnetic tape out of the tape cassette and pressing it against a rotary head when the tape cassette is loaded. CONSTITUTION:When a tape cassette 50 is loaded into a recoding and reproducing device or a reproduction-only device, a loading arm 301 is driven to draw a magnetic tape 54 out of the cassette 50. Then the tape 54 is pressed against the rotary head 226 of the recording and reproducing device, etc. As a result, the relative speed between the head 226 and the tape 54 can be extremely increased with the use of the head 226 compared with the use of a fixed head. Thus the frequency band of the tape 54 is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a magnetic door loading structure, and relates to a magnetic tape loading structure that can be press-contacted.

[Conventional Technique #i] Generally, as shown in FIG. 9, a cassette tape 50 for recording and playback is formed into a box shape as a whole, and has a pair of cassettes made of plastic resin. -/) Bar 751, S
l, the bald part 52 rotatably supported within the cassette halves 51, 51, the other hub 53, and the hubs 52 and 53'! i3 loaded magnetic tape 54
It is full of words.

Also, on the front of the cassette halves 51, 51.

11 openings are provided, and the 14th joint where the two halves 51 and 51 are joined has a force (to form a magnetic curve exposed portion 55 on the front surface of the stozo). be.

Part 16. Then, the magnetic tape 54 becomes the cassette tape 51,
When installed within 51! i. A magnetic head (not shown) provided in the recording/IQ machine or the reproduction-only machine is configured to enter the magnetic tape inlet/output section 55 and come into pressure contact with the magnetic tape 54 to perform Q sound or reproduction. has been done.

These compact cassette tape recorders record and play back only audio, so they cannot record or play back audio.
The fixed magnetic head, which is also used for reproduction, has been removed.

On the other hand, in so-called VTRs or DATs, it is necessary to record and play back not only audio but also images, so the relative speed between the head and the tape is 200 times faster than in the case of audio only. It needs to be more than double that.

Therefore, in VTRs and DATs, recording and reproduction are performed by providing a drum-shaped rotary head, rotating the head once at high speed, and pressing the magnetic tape against the rad for five revolutions. and.

In such VTRs and DATs, when a tape is loaded into a recording/playback machine or a playback-only machine, a loading arm equipped with a locking part of a predetermined shape loads the magnetic tape into the cassette tape case from the front of the cassette. The magnetic tape is taken out from the rotary head, and the taken out magnetic tape is pressed onto the rotary head.

[Problems to be Solved by the Invention] By the way, if recording can be performed using a one-rotation head in a general compact cassette as well as in the case of the above-mentioned VTR and DAT, the gap between the head and the magnetic tape would be reduced. Since the relative speed can be increased, the frequency band can be increased, and the dynamic range and S/N ratio can be improved.

However, in commonly used compact cassettes, the cassette tape 5 is
The width of the magnetic tape exposed portion 55 formed on the front surface of the magnetic tape holder 10 is short, so the recorder/player is equipped with an arm and its driving device similar to the loading arm used in a VTR. , the arm is attached to the magnetic tape exposed portion 55
It is not possible to insert the magnetic tape 54 into the magnetic tape and take it out, and it has been impossible to use the conventional compact cassette as it is and apply it to a rotary head.

Therefore, one aspect of the present invention was created for the purpose of increasing the frequency band of a cassette tape by using a rotating head.

[Technical Means for Solving the Problems] In order to solve such technical problems, the present invention provides a magnetic tape surface of the cassette tape that extends inward and penetrates in the thickness direction of the cassette tape. While forming a recess, a recording/reproducing machine or a reproduction-only machine is provided with a loading arm whose tip end is disposed inside the upper recess and inside the magnetic tape.

When the cassette tape is loaded into a recording/playback machine or a playback machine, the loading arm is driven to pull out the magnetic tape from inside the cassette tape and bring it into pressure contact with the rotating head.

Furthermore, the material of the magnetic tape 101 housed in the cassette tape body 100 according to this embodiment is not limited, and includes polyester, metal, and the like. Furthermore, the cassette tape main body 100 according to the present embodiment is configured so that it can be used even when the cassette tape main body 100 is alone without being stored and fixed in the cassette tape case 200. The cassette tape main body 100 can also be used as is in a recorder/player having a structure in which it can be loaded.

Furthermore, in the above embodiments, the case where the reinforcing panel portion constituting the cassette tape body is made of a metal with high magnetic permeability and conductivity has been described as an example, but the present invention is not limited to the above embodiments.

Further, in the above embodiment, the magnetic tape loading structure according to the present invention was explained using a cartridge-type cassette tape l consisting of a cassette tape body 100 and a cassette tape case 200. The present invention is not limited to any conventional compact cassette, as long as it is provided with a recessed portion through which the magnetic tape is exposed.

In one embodiment, the cassette tape body 100
The recessed portion 3 where the magnetic tape is exposed in the magnetic tape exposed portion 55 of
06 is provided as an example, the location where the recess is provided is not limited to the 1 m magnetic tape exit portion 55.

"Effects of the Invention" As described above, when a cassette tape is loaded into a recording/playback machine or a playback-only machine, the loading arm is driven to pull out the magnetic tape from the inside of the cassette tape. When recording using a rotating head, the relative speed between the head and the magnetic tape is different from when using a fixed head. t significantly compared to
can be raised. As a result, the frequency band of the magnetic tape can be increased, and musical characteristics such as dynamic range and S/N ratio can be improved.
