Abstract

PURPOSE:To miniaturize a cassette receiving shelf and to simplify the structure of a handler by providing a belt carrying mechanism in respective receiving rooms, which are provided in the receiving shelf, and driving this belt carrying mechanism by a driving mechanism which is provided in the handler. CONSTITUTION:A handler 6 is stopped in front of a receiving shelf 17 of a selected cassette 1 and a lever 5 is pushed-out in the direction of the receiving shelf 17 by a lever 14 with revolving fulcrums 2 and 4 as centers respectively by pulling a plunger 13. Thus, a driving roller 15 presses a roller 16 for belt in the receiving shelf and the belt in the receiving shelf 17 moves the cassette 1 to the handler 3 side by a moving roller 15. Thus, since the cassette can be moved by the driving force of the external handler 6 without driving the driving belt in the receiving shelf 17 in the internal part of the receiving shelf 17, the structure is simplified and the handler can be made compact.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic cassette changing device for continuously reproducing and recording information from a plurality of recording media.

[Prior Art] In a conventional automatic cassette exchange device, the mechanism for taking the cassette in and out of the storage shelf is usually to pull it out using a handler or to place handles 1 to 1 on both sides of the cassette in the storage shelf. It requires a handler or a complicated mechanism to do something like put it in and take it out.

[Problem to be solved by the invention] As mentioned above, in the conventional automatic cassette exchange device, the mechanism of the handler is complicated, and when the cassette is taken out, the cassette and the bottom surface of the cassette storage shelf are damaged due to friction. Another drawback is that the mechanism for picking out both sites of the cassette requires space on both sides of the cassette. In addition, in order to store cassettes efficiently and to prevent the cassettes from protruding beyond the storage shelves, it is necessary to install rollers and belts in each storage compartment of the cassette storage shelf, and to install drive mechanisms for these rollers and belts in each storage compartment. The problem was that the storage shelf itself became large and the cost was high.

The present invention has been made to solve these problems, and provides an automatic cassette exchange device consisting of a cassette storage shelf that takes up little space and has a simple structure, without damaging the cassettes or the cassette storage shelf when taking out the cassettes. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the automatic cassette exchange device of the present invention is provided with a belt conveyance mechanism in each storage chamber provided in the storage shelf, and this belt conveyance mechanism is connected to the inside of the handler. It has a configuration in which it is driven by a drive mechanism provided in the.

[Function] According to the present invention, instead of transmitting the driving force for driving the rollers of the storage shelf from the storage shelf, the driving force from the handler allows the handler to go to the storage chamber of the selected cassette and pull out the cassette. It is something.

[Embodiment] FIGS. 1 to 4 are side views schematically showing the main parts of an automatic cassette exchange device according to an embodiment of the present invention, and FIG. 5 is a perspective view showing the system of the automatic cassette exchange device. It is a diagram.

In FIGS. 1 to 5, ■ is a cassette containing a recording medium, 2 is a rotational fulcrum of the lever 14 attached to the plunger, 3 is an upper roller on which the second part of the cassette rests, 4 is a fulcrum of a lever 5, and 5 is a roller ( Lever that directs the part (including the held part),
6 is a handler of the cassette transfer section, 7 is a rubber belt that sends the cassette, 8 is a roller for the belt, 9 is a drive roller that rotates the rubber belt 7, 10 is a motor of the drive section, 11 is a screw receiver that sends the handler, 12 is handler 6
13 is a plunger that presses the drive roller 9, 14 is a lever that contacts the plunger 13, 15 is a roller that drives the belt on the shelf, 16 is a roller for the belt in the storage shelf, 17 is a hole that holds the plural storage chambers. 18 is a VTR for recording and reproducing, 19 is a cassette insertion slot, 2o is a handler vertical drive section of the cassette transfer section, 21 is a handler left and right drive section that sends the handler 6 left and right, and 22 is a handler left and right drive section. A feed screw for moving left and right, 23 is a guide rail for the handler.

In the above configuration, FIG. 1 shows a state in which the handler 6 has stopped in front of the storage shelf 17 of the selected cassette 1, and FIG. With the lever 5 as the fulcrum, the lever 5 moves the storage shelf 1
Pushed towards 7.

In other words, the roller 15 that drives the belt on the shelf is pressed against the belt roller 16 inside the storage shelf. Next, FIG. 3 shows the next operation, in which the roller 15 that drives the belt of the pressed shelf
The belt or cassette l in the storage shelf 17 is transferred to the handler 6.
and store the cassette l into the handler 6.

Next, FIG. 4 shows that the cassette 1 is stored in the handler 6, and the belt roller 8, the rubber belt 7, the roller 15 that drives the belt on the shelf, and the lever 5 are separated from the belt in the storage shelf 17 by the plunger 13. , shows the state in which the handler 6 is moving. With this configuration, the drive belt inside the storage shelf is not driven inside the storage shelf 17, but the driving force is transmitted from the handler 6 outside, and the belt inside the handler 6 is also driven inside the handler 6. Since it is driven by a mechanism, the storage shelf 17 does not require a drive unit. Furthermore, the structure of the handler can be simplified compared to conventional handlers that pinch cassettes, and since there is no friction between the cassette and the shelf, there is no possibility of scratching the cassette. Further, the amount of movement of the handler toward the cassette storage shelf is small, and the handler can be made smaller.

[Effects of the Invention] As explained above, the automatic cassette exchange device of the present invention is provided with a conveyance mechanism having a roller and a belt for each storage chamber of a cassette storage shelf, and a cassette is placed on this belt, and the cassette is placed outside the storage shelf. By adding a drive means for transmitting the driving force of the belt conveyance mechanism to the handler, there is no need to provide a drive section for the belt conveyance mechanism in each storage chamber of the cassette storage shelf, and the size of the cassette storage shelf can be reduced. This can simplify the structure of the handler. Furthermore, since the cassettes are taken out from the cassette storage shelves via the belt rollers in each storage chamber, the amount of movement of the handler in the cassette direction is small, which has the effect of making the handler smaller.
