Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a cartridge containing built-in software that can be attached to a computer body and used for various entertainment games and educational purposes.

Structure of a conventional example and its problems A conventional cartridge device, as shown in FIG. 1, for example, has a cartridge body 1 that houses a circuit board 2 on which an integrated circuit element capable of storing software in memory is attached. . Since this cartridge device is a case in which the cartridge body 1, the circuit board 2, and the integrated circuit element are integrated, the user cannot replace it with an integrated circuit element that stores other software. The disadvantage is that when you want software, you have to purchase a new cartridge device.

Therefore, in order to eliminate this drawback, it has been considered to make the integrated circuit element removable from the cartridge body, so that when new software is desired, only a new integrated circuit element is purchased.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a cartridge device having a structure in which the above-mentioned integrated circuit element can be freely attached to and detached from a cartridge body.

Composition of the Invention The present invention provides a cartridge body incorporating a circuit board and a socket having a plurality of contacts electrically connected to the circuit board, and an opening provided in a wall surface of the cartridge body facing the socket. a lid that becomes a part of the wall surface of the cartridge main body by covering the opening; an integrated circuit element provided on the inner surface of the lid; and a contact element provided parallel to a side wall of the integrated circuit element. a plurality of terminals that can be brought into contact with the contacts, a protective wall provided close to the terminals, and a terminal that is provided on both sides of the opening and that is in contact with the contacts in a direction parallel to the side wall. a cartridge device comprising a pair of rotatable drive pieces that move the integrated circuit element to separate the integrated circuit element from the cartridge main body;
The integrated circuit element can be easily replaced, and the terminals of the integrated circuit element cannot be damaged by touching them.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 2 to 6, a socket 6 having a circuit board 4 and a plurality of contacts 5 electrically connected to the circuit board 4 is mounted on the cartridge body 3.
is built-in. An opening 7 is provided in the end face of the cartridge body 3, and the terminal portion of the circuit board 4 faces the opening 7. The circuit board 4 is inserted into the computer main body through the end face provided with the opening 7, and the terminal portions of the circuit board 4 are inserted into the sockets of the computer main body.

Cartridge body 3 facing the socket 6
An opening 8 is also formed on the wall surface (upper surface) of the housing.
This opening 8 is formed around the end face of the cartridge body 3. A lid 9 is provided which becomes a part of the wall surface of the cartridge body 3 by covering the opening 8, and an integrated circuit element 10 to be coupled to the socket is attached to the inner surface of the lid 9. This integrated circuit element 10 can be a PROM or the like that can store software contents. Furthermore, a label 11 indicating the contents of the software is attached to the surface of the lid 9. Furthermore, the terminal 12 of the integrated circuit element 10 is surrounded by a protective wall 13 close to the terminal. This is because the integrated circuit element 10 may be damaged by electrostatic discharge if the terminal 12 is touched by a hand or the like, so this protective wall 13
This protects the integrated circuit element 10 from touching the terminal 12 with hands or the like.

The socket 6 has double outer walls 14 and 15, which are joined at the lower end and have a U-shaped cross section with an open upper end. The protective wall 13 is inserted between the walls 14 and 15.
The contact 5 of the socket 6 extends in a U-shape from the outer wall 14 to the outer wall 15, and is electrically connected to the circuit board 4 at its tip.

As shown in FIG. 5, in order to remove the lid 9 when the lid 9 is attached to the cartridge body 3, drive pieces 16a and 16b are provided on both sides of the lid 9.
is provided. The driving pieces 16a, 16b are configured to rotate about the protruding pieces 17a, 17b as fulcrums, and their tips protrude into the opening 8 so as to be located on the lower surface of the lid 9. The drive piece 16a is moved clockwise, and the drive piece 16b is moved counterclockwise by the spring 18a.
18b. Drive piece 16a,
The rear end of 16b is configured to abut against stoppers 19a and 19b.

With this configuration, as shown in Figure 3,
When the integrated circuit element 10 attached to the lid 9 is connected to the socket 6 with the lid 9 removed, the surface of the lid 9 and the cartridge 3 are connected as shown in FIGS. 2 and 3. It becomes flush with the surface. In this state, the cartridge device is inserted into the computer main body and used. If you want to change the contents of the software, you can prepare another lid to which an integrated circuit element is attached and replace the lid 9 that is currently attached. When replacing both drive parts 16 with your fingers,
By pressing the rear ends of a and 16b at the same time, both driving parts 16a and 16b rotate about protrusions 17a and 17b, lifting the lid 9 and lifting the integrated circuit element 10 as shown in FIG. It can be removed from socket 6. At this time, since the terminal 12 moves in a direction parallel to the side wall of the integrated circuit element 10,
The pressing force from the terminal 12 to the contactor 5 is not large enough to damage the contactor 5, and therefore damage to the contactor can be prevented.

Effects of the Invention As described above, according to the present invention, the integrated circuit element can be easily removed from the cartridge body.
Moreover, when the integrated circuit element is removed from the socket, the terminals of the integrated circuit element are covered by the protective wall, so that they cannot be accidentally touched.
It does not damage integrated circuit elements.
In addition, since the terminal of the integrated circuit element can be moved in a direction parallel to the side wall of the element, the insertion force from the integrated circuit element to the contact when removing the lid from the cartridge body is not enough to damage the contact. This prevents damage to the contacts.
