Abstract

PURPOSE:To hold a cassette with high stability and assuredness at both the inserting position and the working position, by applying the desired elastic energy to the cassette in a cassette case via a roller. CONSTITUTION:When a cassette 2 is put into a cassette case 21, a roller 40 has the rotary movement with the cassette 2. Then the elastic force of a spring 44 is applied via the roller 40 to hold the cassette 2 with high stability and assuredness. Then the case 21 is shifted to the working position, and a lever 27 rocks, and the elastic force produced by the interlocking of a lever 38 and via the roller 40 is applied vertically to the cassette 2 regardless of the rocking of the lever 27. Thus the cassette 2 is pressed and held by support pins 51 and 52 with the even force and without causing any gap, etc. owing to the elastic force obtained by an up-down spring 31 and via the lever 27 and the roller 40. Accordingly the cassette 2 can be held with high stability and assuredness at both its inserting and working positions.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a cassette mounting device that inserts a tape cassette into a cassette storage case and then moves the cassette storage case to an operating position where the reel in the tape cassette engages with a reel stand. When the tape cassette inserted into the cassette storage case is stably held within the storage case and the cassette storage case is moved to the operating position, the tape cassette is held stable and stable by a predetermined pressing force. It is designed so that it is suppressed and held. This will be explained based on Figure 1. FIG. 1 is a side view of the cassette loading device in the operating position, where 1 is a cassette storage case having an opening 1a for inserting a cassette on one side, 2 is a cassette, and 3 is an upper guide for pressing the cassette 2 in the operating position. , 4 is a support pin that supports the cassette 2 in the operating position, 16 is the board of the main body, 6 and 6 are pins installed on the side of the cassette storage case 1, and 7 and 8 are rotating pins provided on the main body side. The fulcrum pin 9.10 is the pin 5, 6 and the rotation fulcrum pin 7.
．． 11 is a pin implanted in the rotating lever 10, 12 is a pin provided on the main body side, 13 is a lift spring, and the lift spring 13 has a winding part at both ends, The windings are each loosely passed through a pin 11, 12. Next, to explain this operation, from the state shown in FIG.
When the lever is rotated clockwise by eject means (not shown), the pin 12 is fixed to the main body, while the pin 11 provided on the lever 10 gradually rises, so that the lifting spring 13 gradually rotates, and when the pin 11 comes above the line connecting the rotation fulcrum pin 8 and pin 12, the force of the lifting spring 13 becomes a force that biases the rotation lever 10 clockwise. The cassette collection case 1 will rise depending on the power. The movement to the operating position is the opposite of the above-mentioned operation; the cassette storage case 1 is pushed up, and when the pin 11 is below the line connecting the rotation fulcrum pin 8 and the pin 12, the lifting spring 13 opens. The force acts as a force that urges the rotating lever (-10) counterclockwise, and this pushing down force presses the cassette 2 with the upper guide 3 of the cassette storage case 1, causing the cassette 2 to It is crimped onto the support pin 4. However, in such a conventional configuration, the part of the cassette case 1 into which the cassette 2 is inserted naturally needs some play, and for example, the direction in which the cassette 2 is inserted is slightly tilted downward. If the cassette 2 is inserted horizontally, it may come out even if it is inserted through the opening, or even if it is inserted horizontally, the lid (to protect the magnetic tape in the cassette 2)
The disadvantage is that the cassette 2 moves within the cassette storage case 1 due to the force acting on the cassette 2 when opening the cassette (not shown). In addition, in the method of pressing the entire surface of the cassette 2 with the upper guide 3 and crimping it to the support pin 4, the cassette storage case 1
Naturally, warping of the upper guide 3 and warping of the cassette 2 are possible, so the upper guide 3 and the cassette 2 do not come into close contact with each other, and the entire body cannot be pressed evenly, resulting in pressing only in one place, causing the cassette 2 and the support There are drawbacks such as a gap occurring between the pins 4.

The present invention aims to solve such problems,
One embodiment thereof will be explained based on FIGS. 2 and 3.

21 is a cassette or storage case, 22.23 is a pin installed on the side of the cassette storage case 21, and 24 is a board 34.
(The side plates are on both sides of the cassette storage case 21, but only one side is shown in the figure.), 26.
Reference numeral 26 denotes a rotation fulcrum pin implanted in the side plate 24, 27 a first rotation lever whose one end is rotatably supported by the pin 22 and the other end by the rotation fulcrum pin 26, and 28, one end is rotatably supported by the rotation fulcrum pin 26; pin 23k
.

a second rotating lever whose other end is rotatably supported by the rotating fulcrum pin 26; 29, a spring pin implanted in the first rotating lever 27; 30, a spring pin implanted in the voice plate 24; 31 is a lifting spring, and winding portions 82.3 are provided at both ends of this lifting spring 310.
3 are provided, and these winding portions 32 and 33 are rotatably supported by the spring pin 2e and the spring pin 30, respectively. 36 is a connecting rod rotatably supported by a side plate (not shown) provided on the base plate 34; one end of 36 is fixed to the connecting rod 36, and a long hole 37 is provided at the other end. It is a connecting lever. Reference numeral 38 denotes a swing lever whose one end is rotatably supported by the pin 22, 39 is a roller pin implanted at the other end of the swing lever 38, and 4° is a roller rotatably supported by the roller pin 3e. , 41 is a stopper pin provided on the first rotating lever 27 for regulating the rotating position of the swinging lever 38, and 42 is a bent portion 43 provided on the swinging lever 38, which is the first rotating lever. Bend part provided at 27, 44
is a spring, and this spring 44 is connected to the bent portions 42, 43,
The swing lever 38 is always biased clockwise.

Next, to explain this operation, when the storage case is at the cassette insertion position shown in FIG.
When the cassette 2 is inserted, the roller 4o is rotated by the cassette 2 in the direction of the arrow. The inserted cassette 2 is moved by the spring 44 by the roller 40.
The cassette storage case is pressed against the lower surface of the cassette insertion portion 21 according to the elastic force of the cassette storage case 21 (see FIG. 2). Next is the operation of attaching cassette 2 to the reel color (not shown).
When the cassette storage case 21 is pushed down from the state shown in FIG.
6 rotates clockwise. As the rotation of the first rotation lever 27 progresses and the spring pin 29 comes below the line connecting the rotation fulcrum 26 and the spring pin 30, the force of the lifting spring 31 to open will be applied to the first rotation lever 27. The cassette storage case 21 is biased and moved downward. Also, although the first rotating lever 27 is rotated, if the first rotating lever 27 further rotates, the stopper pin 41 causes the swinging lever 3B to move to the first rotating lever 2.
It is driven integrally with 7. And at the end of the drive,
The roller pin 39 of the roller 4o is located almost directly above the pin 22. In other words, in this state, the swing lever 38
The first rotation does not occur even if a downward biasing force is applied to the par 27, so the lifting spring 31

It acts directly on the roller 40, and the cassette 2 is moved by the roller 40.
are crimped onto the cassette receivers 51 and 52. Furthermore, roller 4
The biasing position by 0 is located approximately at the center of the cassette receivers 61 and 62. Further, when raising the cassette storage case 21, the reverse of the described operation is performed, and the cassette storage case 21 is urged upward and raised to the outside of the apparatus.

As described above, according to the present invention, the cassette storage case,
At the insertion position, the cassette is pressed and held within the cassette storage case by a lip biased by an elastic biasing force, and at the operating position, another strong elastic biasing force is applied to move the cassette storage case. Since the cassette is pressed by the support means, the cassette is stably held both when the cassette storage case is at the cassette insertion position and when it is at the operating position.
