Abstract

PURPOSE:To attain simple and assured loading/unloading of a bubble memory cassette by using a spring member which presses the cassette to the insertion side and a cassette unloading lever. CONSTITUTION:When a bubble memory cassette 4 is inserted along a guide 2a, a projection of the cassette 4 touches a pawl part 11a of a cassette unloading lever 11. When the rear edge of the projection 6 is positioned at the front of the part 11a, the lever 11 is turned clockwise by the force of a twist spring 12. Thus the part 11a interlocks the projection 6, and a female connector 5 is completely combined with a male connector 3. Thus the cassette 4 is set. Then the lever 11 is turned counterclockwise, and therefore the part 11a is detached from the projection 6. Then the cassette 4 comes out by the force of a spring 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a cassette-type bubble memory device, and more particularly to a setting mechanism for a puzzle memory cassette.

[Purpose of the invention]

An object of the present invention is to provide a cassette-type bubble memory device in which a bubble memory cassette can be easily and reliably set and removed.

[Inplantation of invention]

The present invention provides a bubble memory cassette) K protrusion, and the cassette set body includes a spring member that presses the bubble memory cassette toward the insertion side, and a spring member that is rotatably provided and engages with the protrusion to insert the bubble memory cassette into the bubble memory cassette. The device is characterized by being provided with a claw portion for locking the lever and a take-out lever having an operation portion for unlocking the claw portion by rotating it from the outside.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in FIG. 1, a cassette set body 2 and a male connector 3 are attached to a control board 1. The bubble memory cassette is provided with a female connector 5 and a protrusion 6 which are coupled to the male connector 3. The male connector 3 and female connector 5 are used to connect the terminals of the control board 1 and the bubble memory cassette 4 when the puzzle memory cassette 4 is set, and are a two-piece connector for printed circuit boards.

The cassette set body 2 includes a guide 2a12a for guiding the insertion of the bubble memory cassette 4 and an upper plate 2b.

As shown in FIG. 2, on the back surface of the -F plate 2b, there is a screw spring 7 which is biased by the bubble memory cassette projection 6 and urges the bubble memory cassette to the insertion side.
is provided, and this screw spring 7 is held by a spring support 8.9 fixed to the back surface of the upper plate 2b. Further, a bottle lO is installed on the back side of the upper plate 2b, and this bottle lO is installed on the back side of the upper plate 2b.
A take-out lever 11 is rotatably provided at O. The take-out lever 11 has a claw portion 11a that engages with the protrusion 6 when the bubble memory cassette 4 is set, and an operating portion 11b that protrudes from the front surface of the top plate 2 so that it can be operated externally. Further, on the N side of the upper plate 2b, the ejecting lever 1 is provided.
The claw portion 11a of the bubble memory cassette 4 is connected to the protrusion 6 of the bubble memory cassette 4.
A torsion spring 12 is provided which biases the ejection lever 11 into engagement with the ejection lever 11, and this torsion spring 12 is held by a spring support 13, 14 fixed to the back surface of the top plate 2b.

Next, the effect will be explained. bubble memory cassette 40
To set, as shown in FIG. 2(a), the bubble memory cassette 4 is pushed in along the guides 2a, 2a. At this time, the bubble memory cassette's current protrusion 6 is
1, and the take-out lever 11 is in contact with the claw portion 11a of the bottle 10.
It is released counterclockwise using the fulcrum as the fulcrum. Also, the projection 6 causes the screw spring 7 to be rotated by 'I18'. When the rear end of the protrusion 6 is positioned in front of the claw part 11a as shown in FIG. engages with the protrusion 6. This prevents the pull memory cassette 4 from being removed.

In this state, male connector 3 is connected to female connector 5.
are completely connected, and the bubble memory cassette 4 is in the set state.

To take out the bubble memory cassette →, rotate the take-out lever 11 counterclockwise in the set state shown in FIG. 2(b). As a result, the claw portion 11M is removed from the protrusion 6. Since the protrusion 6 is pressed against the insertion force by the screw spring 7, when the claw portion tta is removed from the protrusion 6 as described above, the bubble memory cassette 4 is ejected by the biasing force of the screw 9 and the spring 7.

In this way, when setting the bubble memory cassette 4, simply inserting the bubble memory cassette 4 into the cassette set body 2 automatically locks the bubble memory cassette → into the cassette set body 2, and the bubble memory cassette 4
When taking out the bubble memory cassette 4, the lock is released by simply rotating the take-out lever 11 and the bubble memory cassette 4 is automatically ejected from the cassette set main body 2, making the operation easy.

By the way, in this structure, since the bubble memory cassette 4 is removed by the spring force of the torsion spring 7, the spring force of the screw υ spring 7 includes the force for releasing the connection of the connector 3.5 and the bubble memory cassette. A force is needed to push out →. Therefore, in order to improve the reliability of taking out the bubble memory cassette 4, the spring force of the screw spring 7 must be increased. By the way, when inserting the bubble memory cassette →, the spring force of the screw spring 7 acts as a reaction, so a strong insertion force is required and operability deteriorates. Furthermore, if a failure occurs in the connector 3.5 or the screw spring 7 when the bubble memory cassette 4 is set, the bubble memory cassette 4 cannot be removed by simply operating the removal lever 11.

FIG. 3 shows another embodiment of the invention which eliminates the above drawbacks. A projection 6 is provided between the torsion spring 7 and the take-out lever 11.
A swinging lever 15 is provided which is rotated by υ to deflect the torsion spring 7, and this swinging lever 15 is rotatably mounted on a bin 16 planted on the back surface of the upper plate 2. There is. Further, the take-out lever 11 is formed with a suppressing portion 11c+ that presses the swinging lever 15.

Therefore, when 40 bubble memory cassettes are set, the third
As shown in Figure (a), the protrusion 6 deflects the torsion spring 7 via the swing lever 15, and similarly to the previous embodiment, the claw part tta of the take-out lever 11 engages with the protrusion 6, causing the bubble to bubble. The memory cassette 4 is in a state where removal is prevented.

To take out the bubble sled cassette 4, in the above-mentioned set state, when the operation part 11b of the take-out lever 11 is slightly rotated counterclockwise, the claw part 11a is disengaged from the protrusion 6 and the removal prevention is released.

When the take-out lever II is further rotated from this state, as shown in FIG.
c pushes the swing lever +5, so the swing lever 15 rotates counterclockwise around the bin 16 and pushes the protrusion 6 toward the insertion side. As a result, the connector 5 is forcibly removed from the connector 3.

When the connector 5 is removed in this way, the swing lever 1
The bubble memory cassette 4 pops out due to the spring force of the screw 9 and the spring 7 transmitted to the screw 5.

In this way, since the connector 5 is forcibly removed, the spring force of the screw spring 7 only needs to be the force to push out the puzzle memory cassette 4, and the spring force may be weaker than in the previous embodiment. Therefore, the insertion force of the bubble memory cassette 4 is weak, and the operation becomes easier. Furthermore, even if a failure occurs in the connector 5.5t or the screw spring 7, the bubble memory cassette 4 can be easily taken out by operating the take-out lever 11).

〔Effect of the invention〕

According to the present invention, it is easy to set and take out the bubble memory cassette. In particular, in the structure of claim 2, the connector is forcibly removed when the bubble memory cassette is taken out, so reliability and operability are excellent.
