On the left side of the case body 14, the gaps 16, 17 and the flange 18 formed by the partition wall 15 are provided.
a, a synthetic resin cassette take-out and holding slider (hereinafter simply referred to as “slider”) 22 is inserted into and taken out of the cassette 3 by using the recess 18 and the slot 19 formed by “a”.
It is slidably mounted along. As shown in FIG. 4, the slider 22 is provided with an elongated flat plate-like arm portion 23 having a projection 23a formed by slightly bending a substantially middle portion in one direction.

At one end of the arm 23, an L-shaped engaging portion 24 protruding on one side and a guide plate 25 protruding on the other side are formed. A loop-shaped holding ring 26 is provided so as to connect the respective tip portions. The guide plate 25 is used for the case body 14 described above.
And is formed to have a width larger than that of the arm 23 in the space 16 between the partition wall 15 and the flange 11a.

On the other hand, at the other end of the arm 23, the above-mentioned guide plate 25 is formed.
Is formed, and a finger-holding knob 28 is formed on an upper portion of the support 27. At the lower portion of the support base 27, that is, on both sides near the arm portion 23, a projecting portion shaped to fit into each of the notches 18b formed on the above-mentioned flange portion 18a is formed so as to act as a stopper portion 29. I have.

The slider 22 thus constructed is shown in FIG.
And a part of the holding ring 26 at one end and the guide plate 2 as shown in FIG.
The guide plate 25 is positioned within the space 16 between the partition wall 15 and the flange portion 11a so that the connecting portion connecting the arm 5 to the arm portion 23 passes through the facing space 17 of the partition wall 15, and the other end is supported. The finger hooking knob 28 is positioned in the outer recess 18 of the case body 14 so that the base 27 is passed through the slot 19 of the flange portion 18a, and the arm portion 23 is mounted so as to be positioned in the storage chamber 12.

As a result, the slider 22 is mounted on the support 27
When the stopper portion 29 provided on the side portion is fitted to the enlarged portion 20 formed by the pair of notches 18b, the stopper portion 29
Cannot be slid by contacting the end of each notch 18b with the step of the notch 18b, but by pushing the finger-holding knob 28 and removing the stopper 29 from the enlarged portion 20, the finger-holding knob 28 is When the guide plate 25 is moved within the space 16, the slider 22 slides linearly along the cassette insertion / removal direction.

Next, the operation of storing and taking out the cassette 3 in the cassette storage case 10 constructed as described above will be described. When storing the cassette 3 in the case 10,
As shown in FIG. 1, the cassette 3 is inserted into the storage chamber 12 so as to be inserted from the entrance 13 of the case body 14. In the cassette 3 placed in the storage chamber 12, the engaging portion 24 of the slider 22 relatively enters the notch groove 5 formed on the side surface on the distal end side of the cartridge 1, and the engaging portion 24 engages the shoulder 5a. And the holding ring 26 is pressed against the curved concave portion 6 formed on the inner wall of the notch groove 5 while being pressed and deformed between the inner wall of the notch groove 5 and the flange portion 11a. And the slider 22 is substantially connected.

The cassette 3 is provided in the storage room 1 of the case 10.
When the slider 23 is inserted into the cassette 2, the protrusion 23a of the arm 23 of the slider 22 is pressed by the side wall of the cartridge 1 of the cassette 3, and the other end of the arm 23 is pressed against the flange 18a. As a result, the stopper portion 29 receives a force for maintaining the fitted state with the enlarged portion 20, and therefore, the free movement of the slider 22 is prevented. The cassette 3 has a case 10 in which the holding ring 26 of the slider 22 is pressed into engagement with the concave portion 6 in the cutout groove 5 of the cartridge 1.
It does not fall out of the storage room 12 naturally,
In the storage room 12, it is restrained by the slider 22 and placed in a storage state.

Next, when the cassette 3 stored in the storage chamber 12 of the case 10 is to be taken out, the finger grip knob 28 of the slider 22 is pushed to push the stopper 2 as described above.
The knob 28 is slid in the direction of the entrance / exit portion 13 in the recess 18 while the 9 is removed from the enlarged portion 20 to move the slider 22. As a result, the moving force is transmitted to the cassette 3 via the shoulder 5a of the notch groove 5 in the cartridge 1 of the cassette 3 in contact with the engaging portion 24 of the slider 22, and the cassette 3 is moved by the same moving amount as the slider 22. Is moved. Thereby, the cassette 3 partially jumps out of the entrance 13 of the case 10.

However, even in this state, since the cassette 3 maintains the state of being restrained by the slider 22 by the press-contact locking action of the holding ring 26, the cassette 3 does not come out spontaneously, and the user has the part where the cassette 3 has jumped out. When the cassette 3 and the slider 22 are pulled out with a pulling force exceeding the pressing and locking force of the holding ring 26, the cassette 3 and the slider 22 are released from the case 10.

The cassette 3 is stored in the storage room 1 of the case 10.
2, the slider 22 is moved to the storage position (stopper portion 2).
Even when the cassette 3 is inserted into the storage chamber 12 as it is, even if the cassette 3 is moved to the cassette take-out side without being at the position where the cassette 9 is fitted to the enlarged portion, the shoulder 5 of the notch groove 5 is in the middle of the insertion.
a comes into contact with the engaging portion 24 of the slider 22 and the slider 2
When the arm 2 is in the storage position, the stopper portion 29 is automatically snap-fitted to the enlarged portion 20 by the pressing force received by the protruding portion 23a to be in the locked state.

[0023]

As described above, according to the cassette storage case of the present invention, the cassette is held at the storage position only by being pushed into the case where the entrance is open, so that the cassette does not fall out naturally and can be taken out. The slider can be partially protruded from the case only by moving the finger-holding knob, and then the slider can be pulled out with an appropriate force. This makes it very easy to store and take out and to improve the reliability of maintaining the holding state. it can.
