8 is a perspective view showing an overview of the cartridge ROM 421. FIG. 8A is a view of the cartridge ROM 421 as viewed from above the sub-control board 420, and FIG. 8B is a view of the cartridge ROM 421 shown in FIG. It is the figure seen from the other side.

  The cartridge ROM 421 is obtained by housing a ROM substrate 431 in a rectangular parallelepiped case body 421a having one side surface extending in the longitudinal direction as an opening 421b. As shown in FIG. 8B, an end portion of a ROM substrate 431 having a plurality of terminals is disposed in the opening 421b of the case body 421a. An extending portion 421c is formed at the edge of the opening 421b on both sides in the longitudinal direction of the case body 421a, and a screw hole 421d is formed in the extending portion 421c. Further, as shown in FIG. 8A, a switch portion 421e for switching from a state where data can be written to the ROM substrate 431 to a state where data cannot be written is formed on one side surface of the case body 421a on both sides in the longitudinal direction. ing. This switch part 421e is comprised by the switch piece 421f and the wiring board 432 (refer FIG.9 (c)) stuck on the back side of the switch piece 421f.

  Then, the opening side of the cartridge ROM 421 is directed to the connector 430 and the end of the ROM substrate 431 having a plurality of terminals is fitted to the connector 430, whereby the terminals of the ROM substrate 431 and the terminals of the connector 430 are electrically connected. Is done. Furthermore, the cartridge ROM 421 is fixed to the sub-control board 420 by inserting a screw into the screw hole 421d and screwing it into the printed board. As described above, the cartridge ROM 421 is an example of a cassette body.

  9A and 9B are explanatory views showing the configuration of the switch unit 421e. FIG. 9A is a side sectional view, FIG. 9B is a front view, and FIG. 9B is a rear view of FIG. . The switch piece 421f is formed by cutting out a part of one side surface on both sides in the longitudinal direction into a U shape so that the extending portion 421c side has a leaf spring property. Moreover, the free end part side of the switch piece 421f is formed in a substantially L shape so that it can be operated with a finger.

  A flexible sheet-like wiring board 432 is attached to the back surface of the switch piece 421f (the inner surface of the cartridge ROM 421). The wiring board 432 is formed with one conducting wire portion 432a. Terminals at both ends of the conducting wire portion 432a are electrically connected to the ROM substrate 431, and the conducting wire portion 432a is electrically connected. The ROM substrate 431 is ready to write data. Furthermore, a part of the conducting wire portion 432a passes through the back surface of the switch piece 421f.

  FIG. 10 is an explanatory view showing the operation of the switch portion 421e. As shown in FIG. 10A, the base of the switch piece 421f is obtained by bending the free end of the switch piece 421f to the front side with a finger or a tool. Is plastically deformed, and the wiring board 432 is broken. Then, by removing the switch portion 421e, as shown in FIG. 10B, the conducting wire portion 432a is completely disconnected, and data writing to the ROM substrate 431 becomes impossible. As described above, the switch unit 421e is an example of a write prohibition switch that prohibits external data writing to the storage unit (ROM substrate 431). The switch piece 421f is an example of a switch member that switches from a writing mode in which external data writing to the storage means (ROM substrate 431) is possible to a write prohibiting mode in which external data writing is prohibited. The switch unit 421e is an example of a write prohibition switch that is plastically deformed or disconnected in accordance with the switch operation to the write prohibit mode.

  With this configuration, it becomes impossible to write data to the ROM substrate 431 by a simple operation such as plastically deforming or removing the switch portion 421e. It is possible to protect the data that the original ROM board 431 has from an unauthorized act of overwriting data.

  Note that the base portion of the switch piece 421f may be easily bent by forming a groove in the base portion of the switch piece 421f to make it thin. In addition, a perforation may be formed at a base portion of the switch piece 421f in the wiring board 432 so that the wiring board 432 is easily broken.

[Configuration Example 2 of Cartridge ROM]
FIG. 11 is a perspective view showing an overview of another configuration of the cartridge ROM 421. The same members or members having the same functions as those shown in FIGS. 8 to 10 are denoted by the same reference numerals, and detailed description thereof is omitted.

  A cartridge ROM 421 shown in FIG. 11 is obtained by forming a hole 421g in a portion of the extending portion 421c that faces the free end of the switch piece 421f in the cartridge ROM 421 shown in FIG. Further, in the sub-control board 420, when the cartridge ROM 421 is mounted on the sub-control board 420, a protrusion 401 is erected at a portion facing the hole 421g. Thus, the protrusion 401 is an example of a member that plastically deforms or cuts the switch member (switch piece 421f) when the external storage medium (cartridge ROM 421) is attached to the attachment means (connector 430).

  Therefore, when the cartridge ROM 421 is mounted on the connector 430 of the sub control board 420, the protrusion 401 is fitted into the hole 421g and comes into contact with the free end of the switch piece 421f. Then, the cartridge ROM 421 is pushed in and the ROM substrate 431 is fitted into the connector 430, whereby the switch piece 421f is pushed up by the projection 401 as shown in FIG. 12, and the base of the switch piece 421f is plastically deformed, and the wiring board 432 is broken. As a result, as shown in FIG. 10B, the conductor portion 432a is completely disconnected, and data cannot be written to the ROM substrate 431.

  With this configuration, the operation of plastically deforming or removing the switch portion 421e is automatically performed when the cartridge ROM 421 is attached to the connector 430 of the sub-control board 420. As a result, it becomes impossible to write data to the ROM board 431, and it is possible to protect the data that the original ROM board 431 has from unauthorized actions such as overwriting the data that the ROM board 431 has. It becomes.

[Configuration Example 3 of Cartridge ROM]
13 is a perspective view showing an overview of another configuration of the cartridge ROM 421. FIG. 13A is a view of the cartridge ROM 421 as viewed from above the sub-control board 420, and FIG. 13B is a view shown in FIG. It is the figure which looked at cartridge ROM421 from the other side. The same members or members having the same functions as those shown in FIGS. 8 to 10 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The cartridge ROM 421 shown in FIG. 13 is different from the cartridge ROM 421 shown in FIG. 8 described above in that the switch piece 421f is not formed, but instead a slit 421h is formed on a part of the side surface in the longitudinal direction of the case body 421a. . The slit 421h is cut out from a part of the edge of the opening 421b along the direction in which the cartridge ROM 421 is attached / detached.

  Further, a protrusion 402 is erected in the vicinity of the connector 430 on the sub control board 420. The protrusion 402 is provided at a portion facing the slit 421 h when the cartridge ROM 421 is mounted on the sub control board 420. The protrusion 402 includes a base portion 402a fixed to the sub control board 420 and a push button portion 402b on which a rod-like pin 402c is erected. A concave portion 402d that is the same type as the push button portion 402b and can be stored is formed on the surface of the base portion 402a opposite to the surface facing the cartridge ROM 421. Further, a through hole (not shown) into which the pin 402c is inserted is formed at the bottom of the recess 402d. Normally, the push button portion 402b is supported by the base portion 402a in a state where the pin 402c is inserted into a through hole (not shown) so as not to protrude from the surface of the base portion 402a facing the cartridge ROM 421.

  FIG. 14 is an explanatory diagram showing a configuration in the vicinity of the slit 421h. As shown in FIG. 14A, a flexible sheet-like wiring substrate 432 is attached to the back surface of the slit 421h (the surface on the inner side of the cartridge ROM 421). The wiring board 432 is formed with one conducting wire portion 432a. Terminals at both ends of the conducting wire portion 432a are electrically connected to the ROM substrate 431, and the conducting wire portion 432a is electrically connected. The ROM substrate 431 is ready to write data. At this time, the wiring board 432 covers the side of the opening 421b in the slit 421h, and the vicinity of the bottom of the slit 421h is a space. Furthermore, the conducting wire portion 432a straddles the slit 421h.

  When the cartridge ROM 421 is mounted on the sub control board 420, as shown in FIG. 14B, a part of the side surface of the case body 421a contacts or approaches the protrusion 402. In this state, by pushing the push button portion 402b toward the cartridge ROM 421, as shown in FIG. 14C, the push button portion 402b fits into the recess 402d, and the tip of the pin 402c is near the bottom of the slit 421h. It protrudes into the cartridge ROM 421 through the space.

  When the cartridge ROM 421 is mounted on the sub-control board 420 and the push button section 402b is pushed into the cartridge ROM 421, data can be written to the ROM board 431. Here, for example, when the cartridge ROM 421 is removed from the sub control board 420 for the purpose of illegally writing data to the ROM board 431, the pins 402c and the wiring board 432 interfere with each other, and FIG. As shown in FIG. 5, the wiring board 432 is cut or broken by the movement to the pin 402c, and the conducting wire part 432a is completely disconnected, so that data cannot be written to the ROM board 431. As a result, it becomes impossible to write data to the ROM board 431, and it is possible to protect the data that the original ROM board 431 has from unauthorized actions such as overwriting the data that the ROM board 431 has. become. In addition, since the push button portion 402b and the recessed portion 402d are substantially the same size, when the push button portion 402b is fitted into the recessed portion 402d, the surface of the push button portion 402b and the surface of the recessed portion 402d are on the same plane. For this reason, when the push button portion 402b is fitted in the concave portion 402d, it is difficult to return the push button portion 402b to the original position unless the cartridge ROM 421 is removed and the pin 402c is pressed toward the base portion 402a. Therefore, when writing data, a special work is required, and the number of people who can write data is limited. Thus, the protrusion 402 is an example of a member that plastically deforms or cuts the switch member (wiring board 432) when the external storage medium (cartridge ROM 421) attached to the attachment means (connector 430) is removed.

  Note that the cartridge ROM 421 shown in FIG. 13 uses the pins 402c and the wiring board 432, but the present invention is not limited to this. For example, when the cartridge ROM 421 is removed by bringing the tip of the pin 402c into contact with or close to the substrate surface of the ROM substrate 431, the cartridge ROM 421 may be disabled by damaging the wiring of the ROM substrate 431. . Further, the pins 402 c may be formed in a triangular prism shape so that the wiring board 432 can be easily cut or broken, and the acute angle portion may be directed to the wiring board 432.

  As described above, according to the present embodiment, an external device that can be attached to and detached from the mounting means (for example, the connector 430 (see FIG. 8)) provided on the sub-control board (for example, the sub-control board 420 (see FIG. 8)). The storage medium (for example, the cartridge ROM 421 (see FIG. 8)) is provided with a write prohibiting switch that prohibits external data writing to the storage means (for example, the ROM substrate 431 (see FIG. 8)). For this reason, after writing fair data to the storage means, the data can be written to the storage means from the outside by switching to a data write prohibited state by a write prohibit switch (for example, the switch unit 421e (see FIG. 8)). It becomes difficult. In this way, it is possible to provide a gaming machine that makes it difficult to introduce illegal data and realizes the fairness of the game.

  In addition, according to the present embodiment, when the switch member (for example, the switch piece 421f (see FIG. 8)) is operated to once enter the write inhibit mode, the switch member is plastically deformed or cut. The switch piece 421f (see FIG. 8) is destroyed, and the mode cannot be switched. In this way, it becomes impossible to write data to the storage means (for example, the ROM board 431 (see FIG. 8)) from the outside, making it difficult to introduce illegal data and maintaining the fairness of the game. It is possible to provide a gaming machine that has been used.

  Further, according to the present embodiment, when an external storage medium (for example, the cartridge ROM 421 (see FIG. 11)) is mounted on the mounting means (for example, the connector 430 (see FIG. 11)), the switch member (for example, the switch piece) 421f (see FIG. 11)) is plastically deformed or cut. For this reason, for example, before shipment, an external storage medium (for example, the cartridge ROM 421 (see FIG. 11)) is attached to a sub-control board (for example, the sub-control board 420 (see FIG. 11)). When it is mounted on the storage means (for example, ROM board 431 (see FIG. 11)), it becomes impossible to write data to the storage means (for example, ROM board 431 (see FIG. 11)). The fairness of the data written in is preserved. In this way, it becomes impossible to write data to the storage means (for example, the ROM board 431 (see FIG. 11)) from the outside, making it difficult to introduce illegal data and maintaining the fairness of the game. It is possible to provide a gaming machine that has been used.

  Further, according to the present embodiment, when an external storage medium (for example, the cartridge ROM 421 (see FIG. 13)) is removed from the mounting means (for example, the connector 430 (see FIG. 13)), the switch member (for example, the wiring board) 432 (see FIG. 14)) is plastically deformed or cut, and the external storage medium (for example, cartridge ROM 421 (see FIG. 13)) is attached to the sub-control board (for example, sub-control board 420 (see FIG. 13)). When the connector 430 (see FIG. 13) is removed, it becomes impossible to write data to the storage means (for example, the ROM substrate 431 (see FIG. 13)) from the outside. For this reason, for example, even if an external storage medium (for example, the cartridge ROM 421 (see FIG. 13)) is removed for the purpose of data tampering, data cannot be written, and data can be written to an external storage medium ( For example, this is limited to the case where the cartridge ROM 421 (see FIG. 13) is attached to the attachment means (for example, the connector 430 (see FIG. 13)). Therefore, when writing data, a special work is required, and the number of people who can write data is limited. In this way, except for some people, it becomes impossible to write data to the storage means (for example, ROM board 431 (see FIG. 13)) from the outside, making it difficult to introduce illegal data, A gaming machine that can maintain fairness can be provided.

  Further, according to the present embodiment, since the external storage medium (for example, the cartridge ROM 421 (see FIG. 8)) is a cassette body, the write prohibition switch (for example, the switch unit 421e (see FIG. 8)) is provided. The degree of freedom increases, and it becomes easy to devise to make it difficult to write data to the storage means from the outside. In this way, it is possible to provide a gaming machine that makes it difficult to introduce illegal data and realizes the fairness of the game.
