Description

[Detailed Description of the Invention] This invention relates to a wiper used for cleaning dirt adhering to the surface of a magnetic head or the like.

If dirt or other dirt adheres to the surface of the magnetic head, it will deteriorate the recording and reading performance of the magnetic head, so it is necessary to clean the surface of the head from time to time. Cleaning work is carried out using manual operations.

Conventionally, sweeping was carried out using a cotton swab with fibers entwined at the tip of a long, slender cylindrical rod. Due to the narrowness of the head, it is difficult to clean large areas such as heads with many channels, and if the magnetic head is installed in a secluded area of the equipment, it is difficult to clean a large area such as a head with a large number of channels. Since it is difficult to apply force, it is difficult to sweep evenly and dirt tends to remain. In addition, after the fibers become dirty after one cleaning, the used cotton swab must be discarded and a new cotton swab used, making the work cumbersome.

The present invention was devised to solve the above-mentioned problems, and the purpose of the present invention is to provide a wiper such as a magnetic head that has excellent operability and cleaning power and can be used for multiple cleaning operations. It is about providing.

As a means to achieve this objective, the wiper of the present invention is comprised of a core plate which is made of an elastic long plate, both ends of which are overlapped, and the middle part of which is folded back into a U-shaped cross section; A cleaner unit is formed by a sweeping material such as a non-woven tape wrapped multiple times around the outer circumferential surface and a clamp that clamps the overlapped end of the core plate from above the sweeping material, and the clamp portion is held. It is characterized in that it is removably attached to the tip of the handle in a state where it is held in place.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in FIGS. 1 to 4, the wiper of the embodiment is composed of a handle 1 and a cleaner unit 2 detachably attached to the tip of the handle 1, and the handle 1 is formed in the following manner. The wiper can be easily operated and handled in an appropriate shape corresponding to the shape of the space around the installation location of the magnetic head to be cleaned, and the mounting structure of the unit 2 at the tip can be freely set. obtain.

In the case of the illustrated handle 1, it is formed of a square bar, and the grip portion 1a on the right side of the drawing is slightly curved, and the mounting portion on the opposite side is
Two parallel side plates 1b and 1c with cuts made
The adjustment screw 3 is inserted through a through hole in one side plate 1b and screwed into a screw hole in the other side plate 1c, and the adjustment screw 3 is inserted between the two side plates 1b and 1c. It is formed so that the interval can be freely adjusted.

Next, the cleaner unit 2 includes a core plate 4 formed of a longitudinal rectangular plate-shaped Mylar film or the like, a sweeping material 5 formed of a non-woven fabric tape or the like wrapped multiple times around the outer peripheral surface of the concentric plate 4; Core plate 4 and sweeping material 5
The elastic core plate 4 is formed by a clamp 6 having a U-shaped cross section that clamps the two together.
The middle part is folded back into a U-shaped cross section, and both ends on the right side of the drawing are overlapped.

Note that the core plate 4 may be a thin spring plate made of metal, fiber, or the like.

Further, the sweeping material 5 is formed by tightly winding a long tape in a spiral shape a plurality of times (eight times in the illustration), and is fixed to the overlapped end of the core plate 4 by a clamp 6.

In addition to non-woven fabric, the sweeping material 5 can be made of a durable paper tape with a soft, uneven surface, and can be wound in multiple layers.

To attach the cleaner unit 2 to the handle 1, insert the clamp 6 part of the unit 2 between the side plates 1b and 1c of the handle 1, tighten the adjustment screw 3, and press it onto the handle 1. It is kept fixed.

Next, a method of using the wiper of the embodiment configured as described above and its operation will be described.

First, grasp the grip part 1a of the handle with your hand,
As shown in FIG. 4, the tip edge of the cleaner unit 2 is placed against the surface 7a of the magnetic head 7, and the sweeping material 5 is slid left and right several times while being lightly pressed against the surface 7a.

Through this operation, the surface of the sweeping slope 5 is backed up by the elasticity of the core plate 4, and dirt is removed from the head surface 7a with a reasonably gentle and uniform sliding pressure, and the fallen dirt is swept away. It is swept to the surface of coverage 5.

At the end of such a sweeping operation, or when the sweeping material 5 becomes extremely dirty during the sweeping operation, peel off one outermost layer of the sweeping material 5 to expose the next clean layer. The cleaner unit 2 can be used for the next cleaning operation, and when the innermost layer has been used, the cleaner unit 2 can be replaced with a new unit.

In this type of cleaning work, a wide cleaning surface is swept evenly and with sufficient rubbing pressure, so the handle is designed so that it does not damage the cleaning surface or leave dirt behind, and it is easy to insert the wiper. By preparing several types of shapes, it is possible to easily perform a sweeping operation by selecting and using a handle with an appropriate shape.

Furthermore, since the only consumable part is the cleaner unit, the cost is also low.

As described above, according to the wiper such as a magnetic head according to the present invention, a cleaner unit having a multilayer tape-shaped sweeping material backed up by the elasticity of the core plate can be attached and detached to the tip of the handle, which has an easy-to-operate shape. Since the wiper is configured by attaching it to the wiper, it is possible to effectively sweep dirt from a wide cleaning surface with easy operation, and the cleaning cost is low, improving the operability, effectiveness, and economy of the wiper. It has the effect of improving
