Abstract

PURPOSE:To smoothly move a skate by adhesively fixing the skate sliding face of a guide rail to a face formed at the same height as the skate sliding face in a skate positioning member. CONSTITUTION:A positioning member 13 is fixed directly to a chassis 21 and a sliding face 13a and a plane part 13b of a skate 26 in the positioning member 13 are worked at the same height from a fitting face 13 of the positioning member 13 to the chassis 25. One end of a guide rail 24 is fixed by a screw 30 so as to adhere the sliding face of the skate 26 to the plane part 13b of the positioning member 13. Therefore, a step between the sliding face 13a of the skate 26 in the positioning member 13 and the skate sliding face of the guide rail 24 can be eliminated without considering the thickness of the guide rail 24 and the dimensional error of the fitting member. Thus, the skate 26 can be smoothly and easily moved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape loading device used, for example, in a video tape recorder (VTR) shade, and particularly to a positioning member for a loading kite.

[Prior art] As a technique widely used for tape loading,
The tape is loaded onto a predetermined path by moving a skate provided with a loading kite while being guided by guide rails, and the skate is positioned by abutting against a positioning member.

Loading kite in traditional loading device,
A front view and a plan view of the guide rail and positioning member for the scale 1 are shown in FIGS. 3 and 4.

In FIGS. 3 and 4, the skate 26 is transferred from the guide rail 24 to the positioning member 13 and positioned.

In a tape loading device, a loading kite is essential for accurate positioning.

Therefore, the positioning member for positioning the loading kite, the general skate, and the skate is formed with high precision.

In addition, the positioning member is the chassis that serves as the reference for positioning.
, is fixed directly to.

The guide rail is usually made of a plate-shaped member, and is attached to the chassis 25 through a small member at the 31st m, or as shown in Fig. 4, the guide rail is thicker than the skate sliding surface of the positioning member. Mounted on a lowered surface.

[Problems to be Solved by the Invention] However, the conventional example -1- has the following drawbacks.

In the case of the conventional example shown in FIG. 3, although the positioning member 13 is molded and solidified with good viscosity, the rails 1 to 24 are reprinted via the additional member 31, and the mounting member 31 is Dimensional errors and dimensional errors in the plate thickness of the guide rail 24 cannot be avoided, resulting in a step between the skate sliding surface of the guide rail 24 on which the skate 26 slides and the skate sliding surface of the positioning member 13. was.

Also, in the case of the conventional example shown in FIG. 4, errors in the thickness of the kite rail 24 could not be avoided, and the same problem occurred.

If there is a step on the sliding surface between the skate 1 and the skate 1 between the rail and the positioning member, the skate will hang onto the step and will not move smoothly.

In view of such conventional drawbacks, the present invention makes the sliding surface of the rail and the positioning member at the height of the rotation,
To provide a tape loading device that allows smooth movement of skates.

[Means for Solving the Problems] 1: In order to achieve the above object, the tape loading device of the present invention includes a guide rail on a surface formed at the same height as the skate sliding surface of the skate positioning member. The structure is such that the sliding surface of the skate is tightly fixed.

[Function] In the present invention, a surface having the same height as the skate sliding surface is formed on the side opposite to the sliding surface of the skate 1 of the skate positioning member, and the skate sliding surface of the kite rail is formed on this surface. are tightly fixed to prevent a step from forming on the skate sliding surface of the positioning member and the guide rail.

[Embodiment] Hereinafter, an embodiment of a VTR loading device to which the present invention is applied will be described along the IA side.

Figure 2 does not show the overall configuration of the loading section that pulls out the tape from the cassette and wraps it around the ram from rotation 1 to rotation 1.The loading method is either the loading guy L-, or everything moves parallel to the chassis, with the drum at the center. It is a parallel M loading method that wraps the tape symmetrically on the left and right sides.

In FIG. 2, l designates a tape cassette in which a supply reel 2 and a take-up reel 3 are housed, and a magnetic tape 4 is wound between them.

A loading kite 5, 6°7.8 for loading a tape is inserted into the opening 1 to the deep cassette 1.

Reference numeral 23 denotes a rotating drum to which a magnetic head is attached, and additional volumes are mounted on the sheets 25 at a predetermined angle in a predetermined direction.

13 is the loading kite 5, 6 or the erected scale.
A positioning member for positioning 1-26.

Reference numeral 14 designates positioning members for positioning the skates 27 installed on the loading guys 1 to 7.8, and each is attached to the chassis 25.

24 is a kite rail that moves the skates 26 and 27.

In addition, chassis 25 has posts 9, 10° 11.20

A pinch roller 19 or the like is arranged at a predetermined position.

In Fig. 2, if cassette l is now installed, [7
- Skate 1-2 where Zoinkai 1 to 5 and 6 are installed ☆ 1
6 moves along the groove 24a of the guide rail 24, and the loading guide 7.8 moves along the groove 24b of the skate 27 or the kite rail 24, respectively, and the magnetic tape 4 is pulled out from the tape cassette l and follows a predetermined path. It will be moved to.

The skates 26 and 27 are transferred from the guide rail 24 to the positioning member I3 and the positioning member 14,
When the skates 1-26 and 27 come into contact with predetermined portions of the positioning members 13 and 14, respectively, the skates 26 and 27 are positioned, and the loading is completed.

Unloading is the complete opposite of loading.

Next, the positioning member will be explained in detail.

Positioning member 13 and positioning member 1 in the 21st'l
4 have basically the same structure, the positioning member 13
I will only explain about.

FIGS. 1(a) and 1(b) show a loading guide 5, a skate 26, and a skate 26 in a tape loading device embodying the present invention. FIG. 4 is an IF plane view and an f plane view of the kite rail 249 positioning member 13.

The positioning member 13 is directly fixed to the chassis 25. Sliding surface 13 of skate 26 on positioning member 13
a and the flat part 13b are the chassis 25 of the positioning member 13.
It has been decided that the height should be the same as that of the mounting surface 13c.

One end of the rail 24 to the guy 1 is fixed with a screw 30 so as to be in close contact with the sliding surface of the skate 26 or the flat part 13b of the positioning member 13.

By doing this, the difference in level between the sliding surface 13a of the skate 26 in the positioning member 13 and the sliding surface of the guide rail 24 on the skate 1 can be reduced by the dimensional error in the plate thickness of the guide rail 24, and in the mounting member of the kite rail 24. It is possible to eliminate dimensional errors without considering them, and it becomes easy to move the skates 26 smoothly.

In this case, the plane 13b regulating the guide rail skate sliding surface of the positioning member 13 is formed integrally with the positioning member 13, or a separate member is formed on the skate sliding surface 13a.
It may also be formed by closely fixing it to.

Further, in this embodiment, the present invention is not limited to a detailed explanation of the VTR loading device, but it goes without saying that the present invention can be applied to all tape loading devices that use guide rails, skates, and positioning members. Not even.

[Effects of the Invention] As explained above, the present invention provides chi 1 to 1 on the surface formed at the same height as the skate sliding surface of the skate positioning member.
By closely fixing the sliding surface to the scale 1 of the rail,
In order to manage the dimensional accuracy of the positioning member, it is possible to eliminate the difference in level between the sliding surface of the positioning member and the guide rail, which has the effect of allowing the skate to move smoothly.
