Abstract

PROBLEM TO BE SOLVED: To provide a head cleaner which has high cleaning effect and can be reduced in size without damaging a head or a drum by so constituting the cleaner by a laminated film block. SOLUTION: In a laminated film block 91, resin films 912 and thin nonwoven fabrics 139 are alternately laminated, and an oblique surface 911 is provided. A cleaner unit 9 is fixed to a cleaner arm 5. When a solenoid 8 is not energized, the surface 911 of the block 911 is separated from a drum 2 by a tensile spring 7, and not brought into contact with a head 1. When the solenoid 8 is energized, the arm 5 is rotated around a rotary shaft 6, and the surface 911 of the block 91 is pressed to the drum 2. The head 1 is rotated in the direction of an arrow K, and the surface 911 wipes the surface of the head 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head cleaner for a tape device having a rotary head such as a VTR or DAT.

[0002]

2. Description of the Related Art FIG. 6 is a schematic view for explaining the structure of a conventional head cleaner. In the figure, 1 is a head, 2 is a drum for winding a recording tape, and 3
Is a cleaning roller. As shown in FIG. 6, the cleaning roller 3 comes into contact with the rotating head 1 by being pressed against the side surface of the drum. For the cleaning roller 3, a porous and flexible material such as felt or sponge is used. FIG. 7 is a schematic view for explaining the operation of the conventional head cleaner. 4 is a cleaning roller 3
The rotary shaft 5 is a cleaner arm which is fixed to the rotary shaft 4 and rotates around a rotary shaft 6, 7 is a tension spring for urging the cleaner arm 5, and 8 is a solenoid. When the solenoid 8 is not energized, the cleaner arm 5 is urged by the spring 7 and the cleaning roller 3 is separated from the drum 2. When the cleaner arm 5 is pulled by the force, the cleaning roller 3 is pressed against the drum 2. The cleaning roller 3 pressed by the drum 2 rotates around the rotation shaft 4. In this way, the dirt attached to the surface of the rotating head 1 is adsorbed on the side surface of the porous cleaning roller 3.

[0003]

However, in the above-mentioned conventional head cleaner, when trying to remove solid dirt sticking to the surface of the head, the cleaning member must be made abrasive and the hardness of the cleaning member must be increased. Since it does not happen, there was a problem that it damages the head and the drum. On the contrary, in order to remove the liquid-like dirt, it is necessary to use a fibrous or porous relatively soft cleaning member to adsorb the dirt to the cleaning member, but with such a soft member. I can't remove the solid stains that stick to the head. That is, the conventional head cleaner has a problem in that it is difficult to remove both solid and liquid stains adhering to the head surface.

The present invention solves the above-mentioned problems of the prior art by providing a head cleaner that has a high cleaning effect and does not damage the head or drum, and that can be downsized and easily manufactured. Intended to provide a cleaner.

[0005]

To achieve this object, the present invention provides a head cleaner in the form of a block in which a plurality of fibrous or porous films and fibrous or non-porous films are alternately stacked. It is characterized in that it is made of a member.

[0006]

According to the present invention, each film adheres to the surface of the head because it has appropriate rigidity and flexibility as the whole block even if the rigidity is low enough not to damage the head or drum. Efficiently scrapes solid dirt and does not damage the head or drum.
In addition, the fibrous or porous film adsorbs liquid stains.

Embodiments of the present invention will be described below with reference to the drawings. However, the same numbers are given to the same components as the conventional example, and the description is omitted.

FIG. 1 shows a head cleaner according to an embodiment of the present invention. A cleaner unit 9 is composed of a laminated film block 91 and a holder 92. 92
Reference numeral 1 is an attachment hole for attaching the cleaner unit 9 to the tape device, and 911 is an inclined surface provided in the laminated film block. The laminated film block 91 is configured by alternately laminating resin films 912 and thin non-woven fabrics 913.

In order to clean the head of the tape device by using the cleaner unit 9, as shown in FIG. 2, the inclined surface 911 of the laminated film block 91 is brought into contact with the side surface of the drum 2.

3 and 4 are schematic diagrams for explaining the operation of the head cleaner of the present invention. The cleaner unit 9 is fixed to the cleaner arm 5. As shown in FIG. 3, when the solenoid 8 is not energized, the tension spring 7 biases the rotating arm 5, so that the slope 911 of the laminated film block 91 is separated from the drum 2 and contacts the head 2. do not do. As shown in FIG.
When a current is applied to the solenoid 8, the cleaner unit 9 rotates around the rotation shaft 6 together with the cleaner arm 5, and the slope 911 of the laminated film block 91 is pressed against the drum 2. Since the head 1 is rotating in the direction of arrow K, the slope 911 wipes the surface of the head.

FIG. 5 shows the slope 9 of the laminated film block 91.
11 is an enlarged view when the surface of the head 1 is wiped. Since the resin film 912 is laminated, the resin film 912 has appropriate rigidity as a whole and bends flexibly along the surface of the head. As a result, solid stains and the like sticking to the head surface are scraped off. Further, the nonwoven fabric 913 laminated between the resin films 912 is the head 1
Since liquid stains adhering to the surface of the head are adsorbed between the fibers, both solid and liquid stains are wiped off the surface of the head 1.

In this embodiment, the non-woven fabric is used as the film for adsorbing liquid stains, but any material having appropriate pores such as felt, cloth and sponge can be used. Further, as the resin film, a PET film or the like is suitable from the viewpoint of rigidity and durability.

[0013]

As described above, according to the present invention, by constructing the head cleaner by the laminated film blocks, the cleaner member has appropriate rigidity and flexibility, and the head surface has a solid state. Since the dirt is effectively scraped off and a fibrous or porous film is laminated to adsorb liquid dirt as well, the cleaning effect is very large. Further, the cost is low because only the films are laminated.
