Abstract

PURPOSE:To use a magnetic head and a pinch roller as they are and to miniaturize a cassette tape by providing a recessed part on a base part and a reinforcing panel part to penetrate them in the thicknesswise direction and forming a head entering part and a pinch roller entering part with this recessed part. CONSTITUTION:The base part 102 and the reinforcing panel 103 part are provided with the recessed part 112 penetrating them in the thicknesswise direction, and by this recessed part, the head entering part 116 and the pinch roller inserting part 143 are built up. Consequently, no only the length size and width size of the cassette tape 1 but also the thickness size can be shortened, while the magnetic head and the pinch roller as mounted for the existing reproducing device are entered as they are into the head entering part 116 and the pinch roller entering part 143 respectively, so as to be capable of being in close contact enough with the tape. By this method, the magnetic head and the pinch roller as mounted for the existing reproducing device can be used as they are, and the size of a cassette tape as an information storage space can be miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cassette tape that is smaller than a commonly used compact cassette.

[Prior Art] To explain a cassette tape for recording and playback as an example, a cassette tape for recording and playback generally includes a magnetic tape, two hubs, and a frame called a half.

The cassette tape that is currently in widespread use is called a compact cassette with a magnetic tape width of 3.81 mm. A material coated with a binder is used.

That is, as shown in FIG. 9, the compact cassette 50 for recording and playback is formed into a box shape as a whole, and includes cassette halves 51.51 made of thermoplastic resin, and rotatably supported within the cassette halves 51, 51. hub 52.53
and magnetic tape 5 wound around these hubs 52 and 53.
4.

[The problem WU that the invention aims to solve] Recently, portable tape recorders for recording and playback have become smaller and lighter, and their size has been reduced to one size larger than the size of a cassette tape. Later developed, the space used to store information has come to occupy a larger proportion than the hardware itself that performs recording and playback. As described above, as hardware has become more compact, there has been a desire to reduce the size of information storage space.

On the other hand, as shown in FIG. 9, in the tape exposed portion 55 of the compact cassette 50, the front end 56 of the cassette half 51 is bulged into a planar trapezoid, and the thickness of the compact cassette 50 is larger than that of the cassette 50. Opening 57 with a large width dimension
is formed.

When the compact power set 50 is loaded into a recorder/player, etc., the magnetic head and pinch roller are inserted through the opening 57.
enters the compact cassette 50 and performs recording and playback.

By the way, even when cassette tapes are miniaturized, it is necessary to secure an entry area for the magnetic head and pinch roller, but as in the past, an opening with a thickness larger than the width of the cassette tape is If it is installed in the exposed part and used as the entrance part for the magnetic head and pinch roller, the maximum thickness of the cassette tape will be approximately the same as that of a conventional compact cassette, and the length of the cassette tape will be Even if the size can be reduced in the length and width directions, the storage space cannot be reduced in the thickness direction.

- On the other hand, since the magnetic head and pinch roller must be in sufficient contact with the running surface of the magnetic tape, it is necessary to make them larger than the width of the magnetic tape. It was difficult to downsize.

Therefore, the present invention was created with the aim of allowing the magnetic head and pinch roller installed in current compact cassette playback machines to be used as they are, and to downsize the cassette tape as an information storage space. .

The cassette tape main body 100 is smaller than the conventionally used compact cassette, but the magnetic tape inside is the same size as the conventional compact cassette (11 mm). Therefore, the user can record and play back not only one side of the tape, but also both sides, as with conventional compact cassettes.

Further, a cartridge type cassette tape l according to this embodiment
In the cassette tape main body 100 that constitutes the magnetic tape 101, there are reinforced panel parts 110 and 1 made of stainless steel with high magnetic permeability and conductivity above and below the base part 102 in which the magnetic tape 101 is housed.
10 is attached, the cassette tape body 10
Even if there is an object that emits strong magnetism, such as a magnet, near zero, most of the magnetic flux from the object will be absorbed by the highly permeable stainless steel reinforcement panel 110. The magnetic influence on the tape 101 can be minimized. Also, when the recording/reproducing machine operates, the magnetic tape 101 is moved at high speed, causing the magnetic tape 101 to
Even if static electricity is generated due to rubbing between the half and half.

Since the reinforcing panels 110, 110 are made of highly conductive stainless steel, static electricity can be released to the reinforcing panel portions 110, 110 without accumulating in the magnetic tape 101 or the sliding contact area as in the conventional case. As a result, a natural discharge can occur from the reinforcement panels 110, 110 into the air. Therefore, since the J2 tuning fork can reduce the magnetic deterioration of the recorded magnetic tape, it can be used to prevent the natural erasure of recording or recorded content, and furthermore, it can prevent dust from static electricity on the magnetic tape 101. Can prevent adhesion.

Furthermore, the frictional heat generated by the high-speed running of the magnetic tape 101 can be similarly conducted to the reinforcing panels 110 and radiated naturally.
It is possible to effectively prevent deformation of the magnetic tape lot due to heat generated by high-speed running of the magnetic tape lot.

Furthermore, in this embodiment, the cassette tape main body 100
A brake arm 130 is provided on the base 102 constituting the brake arm 130, and the inner end surface 135 of the brake arm 130 is always in pressure contact with the magnetic tape or leader tape wound around the outer hub 108b. It is possible to prevent the take-up hub 1oab from idling after the rotation of the cassette tape has stopped, and to effectively prevent the magnetic tape 101 from sagging caused by the idling.

Further, in this embodiment, a meter pointer 131 is provided on the brake arm 130, and the meter pointer 131 changes depending on the amount of winding of the magnetic tape 101 onto either hub 108a or 108b of the recorder/player. transparent magnetic sheet 109
, 109 on the scale 136 provided on the hub 1.
08&.

The winding amount of the magnetic tape 101 (in other words, the remaining amount of tape) of the magnetic tape 108b is determined by the meter window 1 of the reinforcing panel section 110, 110.
47 and the specific numerical value on the scale 136. Therefore, the user can easily and quickly check the remaining amount of tape, instead of comparing the amount of tape on the supply side and the amount of tape on the take-up side to check the amount of tape remaining as before. This work becomes unnecessary.

As a result, for example, a certain cassette tape has a predetermined time Qf.
When recording is continued from the previous recording end position on a subsequent cassette tape, it becomes possible to easily judge whether or not the remaining tape is sufficient for the time required for recording.

Furthermore, in this embodiment, 4I is used so that the remaining amount of tape can be confirmed by visually checking the position of the meter pointer 131 that reciprocates on the scale 136, but the present invention is not limited to this embodiment. Alternatively, the recorder/player may be provided with an optical device to optically read the position of the meter pointer 131 and display the remaining amount of tape to the user. That is,
When the cartridge-type cassette tape l according to this embodiment is loaded into a recording/reproducing machine, the upper and lower reinforcing panels 103
．． Appropriate light emitting parts and light receiving parts made of, for example, photodiodes are provided at parts facing the meter windows 147 and 147 opened at 103, and the light emitted from the light emitting parts is transmitted to the outer side of the cassette tape case 200 and the meter. Transmit window 147.147, meter pointer 131
The position of the tape may be read by a light-receiving section, the light-receiving section converts the optical signal into an electrical signal, and the remaining amount of tape is displayed on an appropriate electrical display means provided in the recorder/player. It is possible.

Furthermore, since a compact cassette tape recorder/player generally records and plays only audio, a fixed magnetic head is provided for both recording and playback.

On the other hand, in a so-called VTR or DAT, since it is necessary to record and play back not only audio but also a single image, the relative speed between the head and tape must be 200 times faster than when recording only audio. It is necessary to do more than that. Therefore, in VTRs and DATs, a drum-shaped rotating head is provided, the rotating head is rotated at high speed, and a magnetic tape is brought into pressure contact with the rotating head.
It performs regeneration.

In such VTRs and DATs, when the tape is loaded into the recorder/player, the magnetic tape is taken out from inside the cassette tape case from the front of the cassette using an arm equipped with a locking part of a predetermined shape. It is configured to press the removed magnetic tape onto the rotary head.

00, the cassette tape main body 100 can be more securely fixed within the cassette tape case 200.

In this embodiment, as shown in FIG. 1, when the cassette tape main body 100 is used by being inserted into the cassette tape case 200 through an opening 207 provided in the front part 206 of the cassette tape case 200. Although the explanation is given using the example of cassette tape case 2, the present invention is not limited to this example.
An opening is provided on the side of the cassette tape body l.
The OO may be configured to be inserted into the cassette cheese case 200 from its opening.

Further, in this embodiment, the case where the barcode section 150 is provided on the cassette tape body 100 has been described as an example, but the present invention is not limited to this embodiment, and the basic pattern may be the Chinese character "田". , depending on whether each square is filled in or not.
It can express various digital information. If such a so-called "R Carla code" is provided, it becomes possible to include even more information than a barcode.

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, in the cassette tape body 100 according to the present embodiment, even if the cassette tape body 100 is used alone without being housed and fixed in the cassette tape case 200, it is formed in a usable part, so that the five-force setting tape body can be used. The cassette tape main body 100 can also be used as is in a recording/reproducing machine or a reproducing machine having a structure in which the cassette tape main body 100 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.

[Effects of the Invention] As described above, in the present invention, the size of the cassette tape as an information storage space is much smaller than that of a conventional compact cassette, and the head entry section and capstan entry section are The tape is formed by four parts penetrating in the thickness direction, and unlike conventional compact cassettes, the tape exposed part is not bulged in the thickness direction. Therefore, the length and width of the cassette tape are Not only that, it is also possible to shorten the thickness dimension, and as a result, it is possible to store far more cassette tapes as recording media in a limited space than with conventional compact cassettes. . Moreover, since the cassette tape as a recording medium is much smaller and lighter than a conventional compact cassette, good transportability and portability can be ensured.

Further, in the present invention, since both the head entry section and the pinch roller entry section are formed by four parts penetrating in the thickness direction, even if the thickness dimension of the cassette tape is shortened, The magnetic head and pinch roller installed in current playback machines can enter the head entry section and the pinch roller entry section as they are, respectively, and can be brought into close contact with the tape. Therefore, the magnetic head and pinch roller installed in current compact cassette playback machines can be used as they are, and wide versatility can be ensured without degrading the recording and playback characteristics.
