Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cassette type cleaner, and more particularly to a cassette type cleaner capable of cleaning not only a head but also a capstan.

[Background of the Invention] It has been known that a cassette tape recorder, when used for a long period of time, adheres to magnetic heads, capstans, pinch rollers, and other magnetic tapes, dust, etc., thereby hindering good recording and reproduction. I have. Therefore, various cassette-type cleaners having substantially the same shape as the cassette case have been provided as handy cleaners.

As a conventional cassette type cleaner, for example, there is a type which can clean not only a magnetic head but also a pinch roller, a capstan and the like (see FIG. 6). The pinch roller 52 can be cleaned by the felt 51 and the capstan 54 can be cleaned by the felt 53, and each member can be cleaned with a simple configuration.

However, in the above-described conventional cleaner, accuracy is required for mounting the cleaning felt 53 on the capstan 54. For example, the felt 53 is
When the cleaner is set on the cassette recorder, the tip of the capstan 54 collides with the shoulder of the felt 53, as shown in FIG. 7 (a). Not only does the capstan 54 be damaged, but the bristle of the felt 53 comes off and becomes dust, adversely affecting the cassette recorder body.

When the felt 53 is attached away from the capstan insertion portion, the capstan 54 and the felt 53 do not abut at all, so that a cleaning effect cannot be obtained.

Furthermore, even if the felt 53 is mounted at the optimal position, the capstan 54 is a small diameter and rotates at high speed, so the contact portion of the felt 53 with the capstan 54 is deformed by wear, and the final Specifically, the capstan 54 and the felt 53 are completely out of contact with each other, resulting in a state where cleaning cannot be performed.

Further, as shown in Japanese Utility Model Application Laid-Open No. 58-148726, a type in which leaf springs 25A and 26A are interposed at the back is also known. In this case, felt materials 25 and 26 are supported at both ends. Since the movement of the felt material 25, 26 is due to its own deformation elasticity, the leaf springs 25A, 26A are merely a support for preventing over-deformation, and it is difficult to move the felt material smoothly. The same drawbacks occur.

[Purpose of the invention]

Therefore, the present invention provides a capstan hole 21 of the main body case 1 inside the main body case 1 having substantially the same shape as the compact cassette.
The cleaning unit 16 is pressed against the capstan 26 to be inserted from below, and the cleaning unit 16 is supported by the base unit 15 provided in the space S between the two capstans 21 of the main body case 1. As a result, the cleaning unit and the capstan can always maintain an optimal pressure contact state by allowing the cleaning unit and the capstan to always maintain an optimal pressure contact state by being freely movable in the direction B perpendicular to the capstan insertion direction A via the arm unit 14 as a free end.
An object of the present invention is to provide a cassette type cleaner which has the effect of eliminating the above-mentioned drawbacks and effectively removing dirt on the capstan.

[Action]

When the cassette-type cleaner according to the present invention is set in the cassette recorder, first, the tip of the capstan 26 inserted from the capstan hole 21 contacts the cleaning unit 16. The cleaning portion 16 is deformed via the arm portion 14 with the base portion 15 as a fulcrum in order to avoid contact with the tip of the capstan 26 and moves in the direction B perpendicular to the capstan insertion direction A. The insertion is completed smoothly, and when the insertion is completed, the capstan 26 and the cleaning unit 16 are pressed against each other with an appropriate pressing force due to the elasticity of the cleaning unit 16. When the cassette recorder is driven, the capstan 26 starts rotating, and is cleaned by the pressure contact with the cleaning unit 16. At this time, since the rotation direction K of the capstan 26 is directed to the base portion 15 serving as a fulcrum on the pressure contact side with the cleaning portion 16, a force is generated when dirt on the capstan 26 comes into contact with the cleaning portion 16. As a result, the cleaning effect is improved. (If the base portion is disposed on the outer side, the dirt faces away from the base portion and is only stroked, so that a sufficient cleaning effect cannot be obtained.)
When the cassette-type cleaner is removed, the pressure contact between the capstan 26 and the cleaning unit 16 is released, and the cleaning unit 16 returns to the original position.

〔effect〕

Therefore, in the cassette type cleaner according to the present invention, even when the positional relationship between the capstan insertion position and the cleaning unit 16 varies, the cleaning unit 16 can freely move in the direction B perpendicular to the insertion direction A of the capstan 26 as a free end. The cleaning part 16 and the capstan 26 are always pressed against the capstan 26 with the optimum pressing force even when the cleaning part 16 is used for a long period of time, so that the cleaning part 16 is pressed against the contact part. The abrasion is suppressed, and even if the abrasion occurs, the pressing force with the capstan 26 can be maintained by the elastic force of the cleaning unit 16. Moreover, since the base portion 15 serving as a fulcrum of the cleaning portion 16 is present in the space S between the two capstan holes 21, dirt is directed toward the base portion 15 on the pressure contact side of the capstan 26 in the rotation direction K. This eliminates the need for pressure contact such as stroking, improves the resistance to dirt, and improves the cleaning effect.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway plan view of a cassette type cleaner according to the present invention, and a cleaning tape 2 made of a cloth having a hygroscopic property is provided inside a main body case 1 having substantially the same shape as a compact cassette. Reel 3, via part 5,
It is wound on four. Reference numerals 6 and 7 denote cleaning section injection sections. When the cleaning tape 2 comes into contact with the cleaning section, the cleaning liquid in the injection section is supplied to the cleaning tape 2.

Reference numeral 8 denotes a cleaning unit for a pinch roller, and a cleaning unit 9 made of felt, cloth, sponge, leather, or the like at the tip.
Are formed. The cleaning unit 8 can be moved in the front-rear direction with respect to the base 10 by the spring 11.

Reference numeral 12 denotes a support portion for guiding the cleaning tape 2, and base 15 corresponds to both capstan holes 2 of the main body case 1.
A support portion 12 which is fixed in a space S between the first and second portions 21 and guides the cleaning tape 2 extends through a resilient arm portion 13 in a curved shape at the tip. As well as base
The capstan cleaning portion 16 extends through the arm portion 14 having elasticity by 15. Reference numeral 29 denotes a rib for positioning the cleaning unit 16 which is a free end, and a tip of the arm unit 14 so that an initial pressure is applied to the cleaning unit 16.
14a is in pressure contact with the rib 29.

Also, this rib 29 is also in contact with the support portion 12, and
The support portion 12 is also prevented from being deformed inward due to the tension of the cleaning tape 2.

2, the cleaning unit 16 includes a cleaning pad 23 such as cloth, felt, and sponge.
The cleaning pad 23 is supported by a base 24. The base 24 includes the support section 12, the arm sections 13, 14, and the base 15
And are integrally molded with synthetic resin.
4 has deformed parts 17 and 18 and expanded part 19 for improving elastic force.
Are formed.

The upper and lower surfaces of the cleaning pad 23 are formed as curved or inclined surfaces, so that the capstan can be inserted smoothly as described later.

Reference numeral 20 denotes a support section for supporting the intruding magnetic head 22 via the cleaning tape 2. 21 is a capstan insertion hole.

In this embodiment, only the cut-out right side is described for convenience. However, the present invention can also be applied to a type in which a pinch roller and a capstan are inserted on both sides, such as an auto-reverse type tape recorder. To
The same configuration as that described above is provided symmetrically.

When the cassette-type cleaner according to the present invention is set in the cassette-type tape recorder, the capstan 26 of the tape recorder is inserted from the capstan insertion hole 21 as shown in FIG. As shown in FIG. 3 (b), at this time, the tip of the capstan 26 and the above-mentioned cleaning pad 23 of the cleaning unit 16 abut, but the cleaning unit 16 having the cleaning pad 23 is movably held by the arm 14. As a result, the pad 23 smoothly moves in the direction B perpendicular to the insertion direction A due to the insertion of the capstan 26. In this embodiment, since the upper and lower surfaces of the cleaning pad 23 are particularly formed with curved or inclined surfaces, the tip of the capstan 16 is not caught on the cleaning pad 23, and the pad 23 and the capstan 26 are not damaged, so that an extremely good quality is obtained. (See FIG. 3 (b)).

Further, in the present embodiment, the arm 14 is provided. Since it bends slightly not only in the B direction but also in the A direction, the cleaning pad 23
Even if the upper and lower surfaces are not curved or inclined, the impact due to the collision of the capstan 26 can be reduced.

When the reproduction or recording operation of the tape recorder is performed, the pinch rollers 27, 27 invade from the opening 25 as shown in FIG.
Is wound on the reel 3 side. At this time, the capstan 26 is K
The cleaning pad of the cleaning unit 16
23 is pressed from below.

The cleaning tape 2 is supplied from the reel 4, and the cleaning liquid impregnated in the cleaning liquid injection section 7 is supplied to the cleaning tape 2 and contacts the magnetic head 22 and the erasing head 28 to perform cleaning.

In this embodiment, an example is shown in which the capstan is used in a type of auto-reverse tape recorder in which both capstans are driven during reproduction and recording.
Are inserted and driven on both sides during reproduction.

Therefore, the cleaning pads 23 of the above-described cleaning unit 16 abut against the capstans 26, 26 with an appropriate pressing force to clean the capstans 26, 26. The rotation direction K of the capstan 26 on the take-up reel 3 is directed toward the base 15 on the pressure contact side of the cleaning pad 23. At this time, the rotation direction K 'of the capstan 26 on the supply reel 4 is also The capstan 26 is directed toward the base portion (not shown) on the pressure contact side, so that the capstan 26 is properly cleaned also on the supply reel 4 side.

In this embodiment, the cleaning liquid can be injected into the cleaning pad 23 and the cleaning section 9. However, the cleaning tape 2 containing the cleaning liquid is applied to the pinch roller 27.
Is pressed between the capstans 26, so that no cleaning liquid is required to be injected into the cleaning section 9 and the cleaning pad 23, and the cleaning can be performed using the cleaning liquid from the cleaning tape 2. This results in a dry wiping effect, good cleaning can be performed, and the capstan 26 and the pinch roller 27 can be prevented from being too wet.

In the above embodiment, an example is shown in which the present invention is applied to an auto-reverse type cassette tape recorder. However, it is needless to say that the present invention can also be used in a so-called single capstan type cassette tape recorder.

At this time, the erasing head 30 is inserted into one side of the opening 25 as shown in FIG.
And the cleaning unit 16 does not hinder the insertion of the erase head 30,
The erasing head 30 is elastically supported by the above-mentioned support portion 12 and is in pressure contact with the cleaning tape 2 to perform good cleaning.

[Other embodiments]

In the above-described embodiment, the cassette type cleaning having the dedicated cleaning liquid injecting section has been described. However, the dedicated cleaning liquid injecting section may not be particularly provided. For example, the cleaning liquid is supplied to the cleaning pad 23 and the cleaning section 9 described above. It may be impregnated and the liquid supply section may be dedicated. In addition, the present invention can be applied to a cassette type cleaner using a dry cleaning tape, and more particularly, to a cassette type cleaner having no cleaning tape.
