Abstract

PURPOSE:To obtain a computer IC pack which can be easily fitted to a computer main frame or a computer cartridge main body and excellent in appearance by mounting an IC pack for fixing ICs movably on a plane to a computer. CONSTITUTION:An IC22 is formed into a solid construction with an IC holder 30 by bending a connector 24, while the holder 30 is freely shifted in two orthogonal directions in a plane of the reverse surface of a pack case 34 through a flange 32 fitting in a groove 36 of the pack case 34 of an IC pack 2. The IC22 is fixed in the desired position to the pack 2 through the holder 30. As a result, the IC22 and the case 34 can be independently positioned at mounting the pack 2 to a computer 4, and a case 34 serves as a cover with advantage. Consequently, the IC pack which can be easily fitted to a computer main frame or a computer cartridge main body and has an excellent appearance can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a computer IC pack that can be used by being attached to a connector provided on the main body of a computer or a computer cartridge. For details, please refer to ROM4 or R, which can be used by computer users for video games, business purposes, educational purposes, etc.
A C-Punk that holds AM etc. can be used by attaching it to a computer or a computer cartridge, and by replacing the IC pack as necessary, it is possible to use various software and expand the memory capacity. It is something that can be done.

Conventional configurations and their problems In recent years, computers, especially personal computers, have been equipped with only basic functions, and the application software required by the user is stored in the form of a Fronohy disk, cassette tape, ROM cartridge, etc. It has become increasingly common to supply Among these, especially for low-end PCs, RO is easy to use even for beginners, and there is less worry about incorrect operation.
Currently, there are many that use M cartridges.

In addition, to improve computer functionality, ICs other than ROM
Cartridges are also available for (for example, RAM for expanding memory capacity) or signal conversion circuits for peripheral equipment (for example, interface circuits for printers and floppy disks).

Conventionally, there have been two types of IC cartridges such as R-OM or RAM as described below.

The first type handles the IC alone or in combination with a simple holding means.A connector corresponding to the shape of the RC to be used is provided in a part of the computer body, and the user connects the IC as necessary. It is used as follows. This first type of IC cartridge is generally called an "rIC pack". Therefore, herein, a device that handles an IC alone or in combination with a simple holding means will be referred to as an IC bag. The first type of IC puncture is usually small in size, with exposed re terminals, and an exterior with a coil or lid installed inside the computer body for the purpose of preventing dust from entering. After connecting to
Used with a lid. The first type has the disadvantage that after the IC pack is attached to the inside of the computer main body, a lid provided separately from the IC pack must be attached, and it is time-consuming to replace the IC pack. Another disadvantage is that it is not possible to know from the outside what kind of contents the IC pack contains.

In the second embodiment, the IC is attached to a printed wiring board by soldering, and is used by being built into a plastic case or the like. This form is generally I in a narrow sense.
Since it is called a C cartridge, hereinafter, only this second form will be referred to as an rIC cartridge J to distinguish it from the first form, an "engine C pack."

In the second type of IC cartridge, since the IC is built into the case along with the printed wiring board, the appearance is improved, and there is no need to close the lid after mounting on the computer, making it applicable to frequent replacement. However, in this IC cartridge, a specific IC is fixed inside the cartridge body.

If ICs with different contents are not used, the user must purchase the entire IC cartridge, which has the disadvantage of being expensive.

Therefore, prior to the present invention, we considered a method in which a connector is provided exposed on a computer main body or a cartridge main body, and an IC pack case to which an IC is attached is detachably provided as a lid covering the connector portion. Basically, this IC puncture can be done by simply attaching only the ICj to the IC back case.

It has the advantage of being cheaper than the above-mentioned IC cartridge. Also, compared to the first form described above,
The workability of IC replacement is also good, and you can easily know what type of JCO Uchitani it is by attaching a label with the contents to the IC pack case.

However, in the case of using an IC puncture, for example, the IC is connected to a connector exposed on the computer body, and at the same time, the connector part of the computer body is covered with the IC pack itself.

It is necessary to use the engineering C-punk itself as the outer wall of the computer body. Therefore - IC for IC pack
I need to install it correctly, and also make sure the position of the connector on the computer itself is correct.

There are disadvantages such as not being able to attach the IC to the computer body, and a gap being created between the outer wall of the computer body and the IC pack, resulting in poor appearance.

OBJECT OF THE INVENTION Therefore, it is an object of the present invention to eliminate the above-mentioned drawbacks, provide an IC bag for a computer that can be easily attached to a computer body or a computer cartridge body, and has a good appearance. .

Composition of the Invention The present invention provides for attaching an RC having a predetermined function to an RE holder, covering a connector provided exposed on a computer main body or a computer cartridge main body, and connecting a part of the outer wall of the computer main body or computer cartridge main body an IC pack case constituting the IC pack case, and the IC holder is arranged on the inner surface of the IC pack case so that it can be moved slightly in all directions at least in a plane so that the re can be connected to the connector. The computer I installed is C-nosic.

8 and 9 are sectional views of the MB section in FIG. 3 before and after the IC pack 2 is installed.

In FIG. 3, the IC pack insertion slot 6 of the computer 4
A circuit board 14 is arranged inside the part, and one IC connector 16 and six changeover switches 18 (only three are shown in FIG. 3) are soldered on the circuit board 14. Each terminal is connected in a conductive state.

First, using Figures 3 to 7, connect the IC22 and the connector 1.
The connection structure with 6 will be explained.

As shown in FIGS. 3 and 6, on the inner surface of the IC connector 16, a plurality of metal connection terminals 2o having spring properties are arranged at equal pitches and facing each other. When inserting IC22 held in
It is configured such that an electrical connection can be obtained between the terminal 24 of No. 2 and the terminal 24 of No. 2.

6, as shown in FIG.
After the IC 22 is combined with the IC 22, the terminals 24 of the IC 22 are bent inward to be fixed.

The IC holder 30 is held by sliding the 8-shaped flange portion 32 into a groove 36 of the same shape provided in the lock case 34.

When the IC holder 30 is slid and fitted, the protrusion 38 that prevents removal is bent downward in FIG.
When the C holder 3o is slid to a predetermined position, the protrusion 38 that prevents removal returns to its original state - the IC holder 3o will not come off from the IC pack case.

Furthermore, the IC holder 30 and the IC pack case 34 are not completely fixed, but are movable in two directions indicated by arrows X and Y shown in FIG. They are designed to fit together with a gap of about 1L [1m].

To attach the IC holder 30 and IC pack case 34 in a movable state, use the dimensions shown in Figure 6 and Figure 1o.

That is, as shown in FIGS. 3 and 7, the IC holder 3
1G22 held at 0 is connected to the IC connector 16 with its terminal 24 in contact with the terminal 2o of the IC connector 16.
The tC back case 34 is positioned at the center of the IC2.
Regardless of the position in which the IC pack insertion slot 2 is positioned, its outer periphery is positioned around the IC pack insertion slot 6 of the computer 4 independently.

If the IC holder 3o and the IC pack case 34 are completely fixed, the positions of the IC connector 16 and the IC 22 may shift when the IC pack case 34 is positioned due to variations in the processing accuracy and assembly accuracy of individual parts. Then, I
Unreasonable force is applied to the C connector 16, making contact between the terminals unstable and significantly shortening the life of the connector.

Conversely, when positioning IC22 - IC pack case 3
4 and the connector insertion opening 6 are misaligned, resulting in irregular gaps at the fitting portion of the two, which impairs the aesthetic appearance and greatly reduces the product value. However, according to this example,
The IC 22 and the IC pack case 34 are positioned independently of each other.
Since the IC 22 and the IC connector 16 can be smoothly connected to each other, the computer 4 can have a beautiful appearance when the IC pack 2 is attached.

Also, as shown in FIGS. 3, 6, and 7.

The area around the IC connector 16 is the case 2 of the computer 4.

(on-off).

The two actuators 4o for operating the changeover switch 18 are slid and fitted into the IC pack 34 as shown in FIG. Fixed by Here, as shown in FIG. 9, the changeover switch i0H is fixed at the second and fifth positions from the left.

With the above configuration, by fixing the actuator 40 gold in a position that meets the specifications of the IC to be attached to the IC back 2VC, the IC22ff: IC connector 1
6, the selector switch 18 can be operated to automatically select a circuit according to the specifications of the IC 22, and various ICs with different specifications can be connected to one IC connector 16 for use. be able to.

FIG. 11 is a perspective view showing the appearance when the 5-piece C pack 2 is attached to the cartridge main body 5o for a computer, and FIG. 11 is a perspective view showing the appearance when the IC pack 2 is removed from the cartridge main body 6o. It is. IC pack 2
The cartridge body 6 is exactly the same as that installed in the computer 4 shown in FIGS. 1 to 10 above.
The internal structure of the computer 4 is also the same as that of the computer 4 in FIG. 3 except for the external shape, so the connection structure between the IC 22 and the IC connector 16 and the operation of the changeover switch 18 will not be explained again since they will be redundant. In addition, Figure 11, 1st
In the case of FIG. 2, the only difference from FIGS. 2 and 3 is that not only the periphery of the IC pack case 34 but also the small projections 52 are used to position the IC pack case 34 with respect to the cartridge body 60. It is a point.

With the above configuration, the IC 22 and I
It is possible to provide a computer cartridge with excellent aesthetic appearance without irregular gaps around the IC case 34 when the IC pack 2 is connected smoothly to the C connector 16 and the IC pack 2 is installed. The installed cartridge can be connected to a computer and used in the same way as a conventional ROM or RAM cartridge.

It has the advantage that cartridges for signal conversion circuits and the like can be used in common with peripheral devices incorporating a plurality of ICs.

In this embodiment, the method of attaching the IC holder 30 to the IC pack case 34 is to fit the convex protrusion 32 of the IC holder 3o into the concave groove 36 of the IC pack case.

Any method may be used for this as long as the IC holder 30 can be attached to the IC pack case 34 in a movable state.For example, a method such as screwing the IC holder to the IC pack case via a spacer may be used. You can also do that.

Effects of the Invention The computer IC pack of the present invention is capable of storing an IC by attaching an IC holder holding an IC in a movable manner to an engineered C pack case that forms part of the outer surface of a computer or a computer cartridge. When installing the puncture into the computer or cartridge body,
The IC and the IC pack case can be positioned independently.

For this reason, the IC can be connected smoothly without applying excessive force to the connector provided on the main body of the computer or cartridge, making the contact of the terminal unstable, or
The life of the connector will not be significantly reduced. A folded IC pack case can increase its commercial value without impairing its aesthetic appearance due to irregular gaps between the IC pack case and the fitting portion on the outer surface of the computer or cartridge.

In addition, if you attach a label that displays the contents of the IC to the surface of the IC pack case, you can visually see the contents of the installed IC pack, and it is easy to replace the IC pack. It is possible to provide a small and inexpensive IC pack that can be replaced frequently without touching it, and its practical effects are great.
