Abstract

PURPOSE:To enable the obtaining of a magnetic recorder/reproducer carrying a highly workable and reliable reel base by applying an adhesive resin on a receiving surface of the supply reel base. CONSTITUTION:A urethane resin 6 is applied on the top of a supply reel base 1. Then, a reel 9 wound with a magnetic tape 8 is made to abut on the urethane resin 6 applied on the top of the supply reel base 1 of a magnetooptical recorder/reproducer to position. This allows the transmission of a rotating force of the supply reel base 1 normally making a reel hook 2 on the top of the supply reel base 1 abut a groove part within the reel 9 thereby improving workability in bonding a rubber sheet on the supply reel base 1 and reliability in peeling of the robber sheet off the supply reel base 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording/reproducing apparatus such as a video tape recorder using a magnetic tape as a recording medium.

2. Description of the Related Art Magnetic recording and reproducing apparatuses using magnetic tape are widely used as magnetic recording and reproducing apparatuses, such as for household magnetic recording and reproducing purposes and for magnetic recording and reproducing in computers.

The prior art will be explained below with reference to the drawings. FIG. 3 is a sectional view of a supply reel section of a conventional magnetic recording/reproducing device. Third
In the figure, 1 is a supply reel stand, 2 is a reel hook, and 3
The reel cap 26 is a regulating spring, 6 is a leaf spring, 7 is a cassette, 8 is a magnetic tape, 9 is a reel, and 1o is a rubber sheet.

The operation of the conventional magnetic recording/reproducing apparatus configured as described above will be explained below with reference to FIGS. 4 and 6.

As shown in Figure 4, wind the magnetic tape 8 -1v9
is positioned by coming into contact with a rubber sheet 10 adhered to the upper part of the supply reel stand 1 of the magnetic recording/reproducing apparatus with double-sided tape. As shown in FIG. 6, during normal operation, the rotational force of the supply reel stand 1 can be transmitted by the reel hook 2 on the upper part of the supply reel stand 1 coming into contact with the groove inside the reel 9.

However, the supply reel stand 1 starts rotating in the C direction, and as shown in FIG. 6, the reel hook 2! J-/l/975E
At the start of rotation until they come into contact, the rotational force is transmitted from the supply reel stand 1 to the reel 9 by bonding the end face of the reel 9 and the supply reel stand 1, as shown in section B of FIG. The rotational force can be transmitted by holding both members by the frictional force between them and the rubber sheet 10.

Problems to be Solved by the Invention However, in conventional magnetic recording and reproducing devices, the rubber sheet was adhered to the supply reel using double-sided tape, which had problems in that it had poor workability and was easily peeled off.

SUMMARY OF THE INVENTION In order to solve the problems of the prior art described above, it is an object of the present invention to provide a magnetic recording/reproducing apparatus equipped with a supply reel stand that has good workability and reliability.

Means for Solving the Problems In order to achieve the above object, the magnetic recording/reproducing apparatus of the present invention is characterized in that an adhesive urethane resin is applied to the upper part of the supply reel stand.

Effects According to the configuration of the present invention, it is possible to improve the workability of adhering the rubber sheet to the supply reel stand and to improve the reliability of peeling of the rubber sheet from the supply reel stand.

Example Below, regarding a magnetic recording and reproducing device according to an example of the present invention,
This will be explained with reference to the drawings.

FIG. 1 shows a supply reel stand of a magnetic LQ reproducing apparatus according to an embodiment of the present invention. In Fig. 1, 1 is a supply reel stand, 2 is a supply reel stand;
3 is a reel hook, 3 is a reel cap, 4 is a urethane resin, and 5 is a regulation spring.

In the above, the urethane resin (4) (d) is a sticky urethane resin dissolved in an organic solvent and applied to the upper part of the supply reel stand 1 to a thickness of several microns.

The operation of the magnetic recording/reproducing apparatus according to one embodiment of the present invention constructed as described above will be described below with reference to FIGS. 2 and 6.

As shown in FIG. 2, the reel 9 on which the magnetic tape 8 is wound is positioned by coming into contact with the urethane resin 6 coated on the upper part of the supply reel stand 1 of the magnetic recording/reproducing apparatus. As shown in FIG. 5, during normal operation, the rotational force of the supply reel stand 1 can be transmitted by the reel hook 2 on the upper part of the supply reel stand 1 coming into contact with the groove inside the reel 9. but,
When the supply reel stand 1 starts rotating in the C direction and the rotation starts until the reel hook 2 and reel 9 come into contact as shown in FIG. As shown in part B of FIG.
The rotational force can be transmitted by holding both members by the frictional force between the end face of the supply reel and the urethane resin 6 applied to the supply reel stand 1.

As described above, according to this embodiment, by applying urethane resin to the supply reel stand, it is possible to obtain the same effect as when a rubber sheet is adhered to the supply reel stand.

As described in detail, according to the present invention, the same function as that achieved by adhering a rubber sheet to the supply reel stand with double-sided tape is made possible by applying urethane resin to the supply reel stand. As a result, it is possible to improve workability and reduce the number of parts when manufacturing the supply reel stand, and as a result, it is possible to achieve the excellent effect of being able to reduce costs.
