Abstract

PURPOSE:To ensure an assured opening operation and to load a cassette at a prescribed position by using an interlocking/pressing member which is turned by a spring expanded by the shift of a slide lever and interlocks the groove part of the cassette to hold and fixed the cassette. CONSTITUTION:A link arm pin 13 slides toward an arrow head as a cassette holder 2 is put into a cassette holder set at a cassette-up position and then a top plate 3 is pushed down. When the plate 3 is pushed down more, the pin 13 touches a guide part 23 of a slide lever 16. Thus the lever 16 pushed and moved toward an arrow head (c). Then a fixed lever spring 22 is expanded to turn a fixed lever 20 counterclockwise. In this case, the lever 20 interlock a groove part 24 of the cassette 2 to lock the cassette 2 and at the same time the lever 20 presses down the cassette 2 to hold this state. In such a way, the cassette 2 is fixed at the cassette holder and opened surely. Then the cassette 2 is loaded at a prescribed position.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting device for cassettes having magnetic tape.

BACKGROUND OF THE INVENTION A conventional cassette loading device will be described below with reference to the drawings. FIG. 4 is an explanatory diagram of the operation of the conventional cassette loading device, in which the cassette holder 1 is moved to the cassette set-up position (position 1A where the cassette 2 can be inserted into the cassette holder 1, indicated by the two-dot chain line in FIG. 4). ) and the cassette down position (cassette mounting position 1B, 4th position)
The cassette up-and-down mechanism section that moves the cassette up and down between the position shown by the solid line in the figure), the opener 27 rotatably supported by the cassette holder 1, and the side plate (not shown) that stands upright on the board 25 and is fixed with screws etc. It consists of an opener pin 26 implanted in the opening (not shown).

The opener 27 is always biased in the direction of arrow A by an opener spring 28, and is in contact with the cassette lid 29. Furthermore, the cassette lid 29 is always urged in the direction of arrow A by a cassette lid spring (not shown, mounted inside the cassette).

The operation of the conventional cassette loading device configured as described above will be described below. As the cassette holder 1A in the cassette setup position containing the cassette 2 is pressed and lowered to the cassette down position, the opener 27 is rotated by the opener pin 26, and the cassette lid is in contact with the opener 27. 29 is rotated and the cassette lid 29 is opened in the cassette down state.

Problems to be Solved by the Invention However, in the above configuration, as the cassette lid 29 rotates, the biasing force of the cassette lid spring increases and the cassette 2 moves in the direction of arrow A, and the cassette 2 is installed in a predetermined position. Furthermore, the cassette lid 29 that had been in contact with the opener 27 comes off the opener 27, and the opening operation of the cassette lid 29 is no longer performed.

In view of the above problems, the present invention fixes the cassette 2 to the cassette holder 1 when lowering the cassette 2 from the cassette set-up position to the cassette-down position, and ensures that the opening operation of the cassette lid 29 is performed to keep the cassette at a predetermined position. To provide a cassette mounting device that allows the cassette to be mounted.

Means for Solving the Problems In order to solve the above problems, the cassette loading device of the present invention includes a pin that is linked to the loading operation, a slide lever that is moved by the bin, and a groove of the cassette for other than the loading operation. an engagement pressing member that does not engage with the cassette, but is rotated by a spring extended by the movement of the slide lever during a loading operation and engages with the groove of the cassette, and presses and fixes the cassette. It is something that

Effects According to the above-described configuration, the present invention has the following features: during loading, a pin linked to loading moves the slide lever, and the movement of the slide lever extends the spring;
By causing the engagement pressing member to engage with the groove of the cassette using the spring, the cassette is fixed, the opening operation of the cassette lid is performed reliably, and the cassette lid is mounted in a predetermined position.

EXAMPLES Below, a cassette loading device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIGS. 2 and 3 are explanatory views of the operation of the cassette fixing mechanism of the same device.

Reference numeral 1 denotes a cassette holder which stores a cassette 2 loaded with magnetic tape, etc., and places the cassette 2 in the cassette setup position.
This is a mounting member for moving the cassette to the down position. 3 is a top plate fixed to the cassette holder 1;

4 and 6 are link arms, which are configured to rotate around the bin 6 as a fulcrum. Further, the link arm 4 is rotatably supported by the cassette holder 1 with a pin 7, and a bottle 1o implanted in the link arm 4 slides in a groove 9 of the side plate 8. Further, the link arm 6 is rotatably supported by a pin 11 on the side plate 8, and a link arm pin 13 embedded in the link arm 6 slides in a groove 12 of the cassette holder 1.

The link arm spring 14 has one end hung on the link arm 6 and the other end hung on the spring hook part 15 of the side plate 8, and urges the link arm 6 in the direction of the spring hook part 15. Reference numeral 16 is a slide lever that engages with a bottle 17 embedded in the top plate 3 and slides. 1
8 is a slide lever spring, one end is hung on the spring hook part 19 of the top plate 3, the other end is hung on the slide lever 16, and the slide lever 16 is hooked on the spring hook part 1.
It is biased in the direction of 9. Reference numeral 20 denotes a fixed lever, which rotates around a pin 21 implanted in the top plate 3 as a fulcrum. 22 is a fixed lever spring, one end of which is connected to the slide lever 16.
The other end is hung on the fixed lever 2o to urge the fixed lever 2o counterclockwise.

The operation of the cassette loading device configured as described above will be described below.

When the cassette holder 1 is in the cassette set-up position (a position where a cassette can be inserted into the cassette holder 1), the link arm pin 13 is in position C shown in FIG. As the cassette 2 is inserted into the cassette holder 1 in this cassette setup position and the top plate 3 is pushed down, the link arm pin 13 slides in the direction of arrow A.

When the top plate 3 is further pushed down, the link arm pin 13 is inserted into the guide portion 23 of the slide lever 1e.
(position d in Fig. 2), the slide lever 16
is pressed and moves in the direction of the arrow.

Therefore, the fixed lever spring 22 is expanded and the fixed lever 20 is rotated counterclockwise. At this time, the fixing lever 20 engages with the groove 24 of the cassette 2, and the cassette 2 is locked, and the fixing lever 20 presses the cassette 2 downward, and when the cassette holder 1 is in the cassette down state, this is the state. hold.

Furthermore, when raising the cassette holder 1 from the cassette down position to the cassette up position, the link arm pin 13 slides in the direction of arrow 2, and the link arm pin 1
The slide lever 16 on which the guide portion 23 is in contact with the
Since the slide lever spring 18 always urges the spring hook portion 19 of the cassette holder 1, it moves in the direction of the arrow O. When the slide lever 16 moves further, the protrusion 25 of the slide lever 16 is attached to the fixed lever 2o.
further, the fixing lever 20 is clockwise rotated by the biasing force of the slide lever spring 18, and the engagement with the groove portion 24 of the cassette 2 is released.

Effects of the Invention As described above, according to this embodiment, it is possible to set the loading, ensure the opening of the cassette, and mount the cassette in a predetermined position. Release the lock and insert the cassette into the cassette holder.

Excellent effects such as easy discharge can be obtained.
