Abstract

PURPOSE:To manufacture inexpensively a tape with simple process by fitting a regulating member regulating a tape running path in the broadwise direction of the tape to a fitting part provided to a guide main body regulating the path in the broadwise direction of the tape and fixing it. CONSTITUTION:A regulating member 2 is formed cylindrically from a material with small friction coefficient. Tongue form fitting parts 1b, 1b are formed incorporatedly with a guide main body 1 in parallel with arms 1a, 1a adjacent to both outsides of the arms 1a, 1a in addition to the conventional shape and structure in the guide main body 1. The part adjacent to the base end of the arms 1a, 1a of the fitting parts 1b, 1b is bent in semi-circular arc form corresponding to the outer circumference of the regulating member 2 and bending parts 1c, 1c are formed. The regulating member 2 is fixed between the arms 1a, 1a of the guidemain body 1 by pressing both ends of the regulating member 2 between the arm 1a at both sides of the guide member 1 and the bending part 1c of the fitting part 1b so as to fit it. In order to fix the regulating member 2, since the regulating member 2 is positioned depending on the position of the bending part 1c, it is not required for positioning.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a tape guide, and more particularly to a tape guide used in a magnetic head or the like for recording and reproducing information on a magnetic tape.

[Prior art]

In a magnetic head that records and reproduces information by sliding a magnetic core through a magnetic gap on a magnetic tape, the sliding position near the magnetic gap of the magnetic tape is accurate and the sliding movement is stabilized. In order to achieve this, a structure in which a tape guide is attached to regulate the travel path of the magnetic tape is widely adopted.

As a conventional structure of such a tape guide, the structure shown in FIG. 1 is known.

In the same figure, the reference numeral 1 is the guide main body, which has arm parts , 1 a , 1 a at both ends on the upper side in the figure.
It is made of a thin rectangular plate made of a material with a low coefficient of friction. The distance between the arms 1a corresponds to the width of a magnetic tape (not shown).

By causing the magnetic tape to run between the magnetic tapes 13, the tape running path is regulated in the width direction of the tape.

On the other hand, what is designated by reference numeral 2 in the diagram is a regulating member that regulates the tape running path in the thickness direction of the arc, and is formed into a rectangular thin plate shape from a material with a small coefficient of friction. The upper end surface of the size regulating member 2 in the figure is formed into a curved surface with an R, and is formed as a sliding surface 2a that directly slides on the magnetic tape.

In the regulating member 2, the sliding surface 2a is the arm portion 1a of the guide body 1,
It is positioned on the side surface of the guide main body 1 using a jig so as to face a predetermined position of the regulating portion of the tape running path between the ia, and is joined and fixed by a method such as spot welding.

However, according to the structure of the tape guide 3 described above, in the manufacturing process, it takes a lot of man-hours to shape the sliding surface 2a of the regulating member 2, and as described above, positioning, joining, etc. of the regulating part 2 is required. This process requires a lot of man-hours and costs are high.

This drawback is not limited to the tape guide for the magnetic head described above, but is common to all tape guides having a similar structure.

〔the purpose〕

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a tape guide that can be manufactured at low cost through simple steps and is suitable for use in magnetic heads and the like.

〔Example〕

Embodiments of the present invention will now be described in detail with reference to the drawings. It should be noted that similar to the above, a tape guide used in a magnetic head is used as an embodiment here, and in each figure, parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

[First Embodiment] Figures 2 to 4 illustrate an embodiment of the present invention.
FIG. 2 shows a regulating part 2 that regulates the tape running path in the tape thickness direction, FIG. 3 shows a guide body 1 that regulates the route in the tape width direction, and FIG. 4 shows the regulating member shown in FIG. 2. 3 shows a tape guide 3 of the present invention, which is formed by fixing the tape guide 2 to the guide main body 1 shown in FIG.

In this embodiment, as shown in FIG. 2, the regulating member 2 is formed into a cylindrical shape from a material with a small coefficient of friction.

1. As shown in FIG. 3, in addition to the conventional shape and structure described above, the guide body 1 has tongue-shaped fitting portions lI) and 1b adjacent to the outside of both arm portions 1a and ia. are integrally formed in the guide body 1 substantially parallel to the arm portions 1a, 1a.

The fitting portions 1b, Ib have portions adjacent to the proximal ends of the arm portions ia, 1a bent in a semicircular arc shape corresponding to the outer periphery of the regulating member 2, forming bent portions 1c, lc.

In the above structure, as shown in FIG.
By press-fitting or otherwise fitting between the bending portions 1C of the guide body 1, the regulating member 2 is fitted with the arm portions 1'a, I
It is fixed facing between a.

As described above, according to the structure of this embodiment, since the regulating member 2 has a cylindrical shape, it can be formed by a simpler process than the conventional method. The groove regulating member 2 is easily fixed by the above-mentioned fitting,
In that case, since the regulating member 2 is positioned by the position of the bent portion 1c, there is no need to perform positioning.

[Second Embodiment] In the first embodiment described above, the regulating portion side 2 was formed into a simple cylindrical shape, but as shown in FIG. This may be used to prevent removal from the fitting portion.

Such a structure prevents the regulating member 2 from coming off,
The reliability of the tape guide is improved. - It goes without saying that the structure of the present invention described above can be applied not only to the tape guide of the I bullish head but also to other tape guides.

〔effect〕

As is clear from the description below, according to the tape guide of the present invention, the regulating member that regulates the tape running path in the thickness direction of the tape is formed in a cylindrical shape, and the regulating member regulates the path in the width direction of the tape. By fitting into the fitting part provided on the guide body, we adopted a structure in which the guide body is fixed facing the path regulating part of the guide body, so it can be manufactured at low cost through a simple process with less man-hours, and can be used in magnetic heads, etc. It is suitable.
