Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tape feeder for automatically supplying a tape cassette stored in a tape stock storage rack to a video tape recorder (hereinafter referred to as VTR) or an audio tape recorder by a robot. .

[0002]

VT capable of storing a large number of tape cassettes
The R tape automatic transmission device has been increasingly used as an automatic service device for automatic broadcasting of programs at broadcasting stations and video at museums and libraries.

Various methods have been proposed for storing cassettes for both large and small tape cassettes in an automatic tape changing device in a VTR. An example of a conventional tape stock storage rack will be described below with reference to the drawings. FIG. 3 shows a conventional tape stock storage rack. In FIG. 3, 21 is a tape stock storage rack body, 22 is a spring with a roller, and 23 is a tape cassette guide.

In FIG. 3, the rack body has opening portions on the front and top surfaces, a tape cassette guide projecting 2-3 mm in the center of the bottom surface, and a side surface of the tape cassette projecting 2-3 mm in the center. A leaf spring with a roller having a shape that engages with the V groove or the U groove is placed. FIG. 4 shows an example in which the tape cassette is placed in a conventional tape stock storage rack. If the tape cassette is provided with a V-shaped groove or a U-shaped groove at a predetermined position on the side surface with the above configuration, the groove is defined in the front-rear direction by the engagement of the spring with the roller, and the left-right direction is defined by the side surface of the rack. By the tape cassette guide, the vertical direction is defined in each position by stacking the racks.

[0005]

However, in the structure of the type shown in FIG. 3, when a small tape cassette is used, it is fixed by a leaf spring with a roller on the side of the rack and a tape cassette guide protruding 2-3 mm at the center of the bottom. Strict dimensional restrictions when inserting a small tape cassette into a rack. Further, in the case of a rack in which the small tape cassette is inserted in the center of the large tape cassette, the spring with a roller attached to the side surface does not come into contact with the rack, so that it is not possible to define left, right, front and back when inserting the rack.

Further, when the tape cassette is taken in and out, a spring with a roller gives a shock to the tape protection lid of the tape cassette, and when it is used for a long period of time, powder is generated due to friction between the tape cassette lid and the tape cassette body. There is a problem that this powder adheres to the tape and causes clogging of the VTR.

In view of the above problems, the present invention provides a tape stock storage rack capable of placing large and small tape cassettes at predetermined positions and not damaging the tape cassettes.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, according to the present invention, an opening for allowing the tape cassette to be attached / detached and a hole or a recess associated with the small tape cassette are fitted, and a spring property is provided. A tape characterized by comprising an arm having a side surface that regulates the position of the small tape cassette and a folding mechanism by inserting the arm into the tape stock storage rack of the large tape cassette. It is a stock storage rack.

[0009]

With the above-mentioned means, when the arm for fitting the small tape cassette and defining the position of the small tape cassette with the rear ends of the rack as fulcrums is inserted into the large cassette, the tip of the arm is pushed by the front surface of the large cassette, and the arm is moved. By rotating around the fulcrum, tape cassettes of different sizes can be placed in the center of the rack.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tape stock storage rack used in an automatic VTR tape feeding apparatus of this embodiment will be described below with reference to the drawings. FIG. 2 shows an automatic VTR tape feeding apparatus in which the present invention is used. 2, 11 is a tape cassette, 1 is a cassette storage rack, 17 is a VTR, 18 is a chuck, and 19 is an XY robot. A device that grips the tape cassette 11 placed on the tape stock storage rack 1 with a chuck 18 and supplies the tape cassette 11 to the VTR 17 by an XY robot 19 that moves the chuck 18, and a predetermined command based on a preprogrammed command or a requested command. By supplying and storing a tape cassette in a predetermined VTR, the tape in the VTR is reproduced and automatically broadcast.

FIG. 1 shows a tape stock storage rack according to an embodiment of the present invention. 1 is a tape stock storage rack main body, 2 is a rack main body side surface, 3 is the same bottom surface, 4 is a small tape cassette position defining arm, 5 is the same small cassette position defining projection, and 6 is a spring for defining the arm position.
5 and 6 are operation explanatory views when the small tape cassette and the large tape cassette are inserted into the rack, respectively. Figure 5
In the above, the small tape cassette is positioned in the center of the rack by the side surface and the stop surface of the small tape cassette position defining arm, and further fixed by the position defining projections by the spring pressure defined in the specified position. In FIG. 6, the front surface of the large tape cassette is pushed down about the fulcrum with the arm tip.

Since the above-mentioned projection is fixedly placed at the rear of the rack, the contact distance with the tape cassette is much shorter than the conventional one.
Damage to the tape cassette is greatly reduced.

A hole for fitting on the tape cassette side,
Alternatively, the recess may be a screw hole or the like, and the shape of the protrusion does not matter. In addition, although the protrusions are formed integrally in the present embodiment, a combination of separate parts may be used.

[0014]

As described above, according to the present invention, the opening for allowing the tape cassette to be attached and detached, the arm having the side surface for regulating the position of the small tape cassette, the hole or the depression associated with the small tape cassette. To provide a tape stock storage rack characterized by including a protrusion having a spring property, and a folding mechanism by inserting the large tape cassette of the arm into the tape stock storage rack. This makes it possible to place tape cassettes of different sizes in the center of the rack with a simple mechanism without damaging the tape cassette with an inexpensive structure.
