Description

  The present invention relates to an electronic circuit board provided with a storage medium in which a game program is stored.

  Pachinko machines such as pachinko machines and slot machines that are installed and used in game halls such as pachinko parlors are given a certain value to game media such as pachinko balls and medals, and the game media acquired by playing games It can be exchanged for various prizes. The gaming machine is provided with various driving devices such as a lamp device and a sound generating device that are operated based on the supply of the game medium, and a control circuit device that controls these driving devices. The game is filled with excitement by actuating them appropriately when performing. In recent years, a symbol variable display device such as a reel display device or a liquid crystal image display device that variably displays symbols is built in, and the variable symbol display is performed so that the identification information is varied and then stopped when the predetermined condition is satisfied. The thing which operates a device has become mainstream. These devices are controlled by a control circuit device.

  A control circuit device disposed in a recent gaming machine is generally one in which a CPU (central processing unit) provided on a board performs electronic control according to a control program. The control program is stored as data in a storage medium such as an IC chip that functions as a ROM (read only memory), and the CPU sequentially reads and executes the control program data from the storage medium according to the gaming state. Control is in progress.

  By the way, as a method of incorporating the storage medium into the control circuit device, the storage medium is attached to the storage medium dedicated substrate, and the terminals provided on the storage medium dedicated substrate are connected to the connection connector provided on the substrate body of the control circuit device. The method of plugging in is known. By using this method, the storage medium can be easily and accurately incorporated at an appropriate location of the control circuit device, and the efficiency of the operation of assembling the storage medium can be improved. Further, when the connection between the terminal of the storage medium dedicated board and the connection connector of the board main body is released, the storage medium can be easily detached from the control circuit device by pulling out the storage medium dedicated board from the board main body. Therefore, when an old game machine is switched to a new game machine, cost reduction and recycling can be performed by replacing only the storage medium dedicated substrate. Further, when maintenance of the control circuit device is performed, the work efficiency when removing the storage medium from the control circuit device is improved, thereby shortening the time required for maintenance.

In addition, a seal seal is affixed to the storage medium dedicated substrate and the substrate body so as to connect the two substrates so that the storage medium dedicated substrate cannot be easily detached from the substrate body. If the storage medium dedicated substrate is forcibly removed from the substrate body, the seal seal remains on the storage medium dedicated substrate or substrate body, so that if the storage medium is illegally replaced, it can be easily detected. .

  However, when the storage medium dedicated substrate is attached to the substrate body by the method described above, the storage medium dedicated substrate on which the storage medium is easily removed and the illegal storage medium is mounted is removed. There was a possibility of being attached to. Even if the seal seal is used as described above, the seal seal can be easily duplicated in recent years. For example, the storage medium dedicated substrate is removed from the substrate body while applying a force to tear off the pasted seal seal. Even if it is removed by force and the debris of the seal sticker is left attached to the storage medium dedicated substrate or the substrate body, it is copied after the storage medium dedicated substrate loaded with an unauthorized storage medium is attached to the substrate body. By sticking the sealed seal so as to cover the storage medium dedicated substrate or the remains of the seal seal attached to the substrate main body, it is possible to hide the trace of the storage medium dedicated substrate removed from the substrate main body. Also, even if a seal seal is affixed, carefully remove the seal seal without leaving a trace, remove the storage medium dedicated substrate from the substrate body, and attach the storage medium dedicated substrate loaded with an unauthorized storage medium to the substrate body. After the attachment, the seal seal is affixed again, so that the trace of removing the storage medium dedicated substrate from the substrate main body can be kept. As a result, there arises a problem that even if the storage medium exclusive substrate is illegally removed, it cannot be found.

  In addition, when recycling the storage medium dedicated substrate or the substrate main body, if a seal seal is used, the seal sticker adheres to the surface of the storage medium dedicated substrate or the substrate main body when the seal seal is peeled off. Since the dedicated substrate and the substrate body cannot be reused, there is a problem that the recyclability is poor.

When the main substrate 24 is stored in the main substrate storage case 25, first, as shown in FIG. 5, the back surface 34d of the substrate body 34 and the upper surface 38a of the base member 37 face each other, and the protrusion 41 is formed in the first hole 34b. The base member 37 is arranged on the back surface 34d side of the substrate body 34 so as to correspond.

  Next, the protrusion 41 is press-fitted into the first hole 34b from the back surface 34d side, and the locking member 43 is inserted through the second hole 34c from the back surface 34d side and pulled out to the mounting surface 34a side. By pressing the protrusion 41 into the first hole 34b, the base member 37 is attached to the substrate body 34 as shown in FIG. After the base member 37 is attached to the substrate body 34 in this way, the terminals 32 a of the storage medium dedicated substrate 32 are inserted into the connection connectors 35 of the substrate body 34. Then, the substrate main body 34 is fixed to the column 44 while positioning is performed so that the through hole 41 a communicates with the hole 45 a of the housing portion 45.

  Next, as shown in FIG. 7, the locking member 43 is inserted into the through hole 32 b of the storage medium dedicated substrate 32. After the locking member 43 is inserted into the through hole 32b, the locking member 43 is disposed so as to face the through hole 41a, and the locking member 43 is inserted into the through hole 41a.

  When the locking member 43 is inserted into the through hole 41a, the locking piece 43b comes into contact with the inner peripheral wall surface of the through hole 41a, and the locking piece 43b is elastically deformed from the engageable position to the insertable position. When the locking member 43 passes through the through hole 41a and is exposed to the lower surface 38b side of the base member 37, the locking piece 43b is returned from the insertion possible position to the engageable position by its own elastic restoring force. At this time, as shown in FIG. 8, the locking piece 43b engages with the edge 38e in a non-detachable state in the direction opposite to the insertion direction. As a result, the tip 39b side of the string 39 is connected to the base member 37 in an inseparable manner.

  Further, since the locking member 43 is housed in the housing portion 45 and is brought into a non-contactable state, there is no possibility that the locking member 43 is broken or that the locking member 43 is crafted. Further, since the accommodating portion 45 supports the edge 38e, when the locking member 43 is inserted into the through hole 41a, the locking member 43 penetrates without dropping the protrusion 41 press-fitted into the first hole 34b. It can be smoothly inserted into the hole 41a.

  After the main board 24 is thus housed in the case body 25a, the lid 25b is closed and locked. Through the above process, the main board 24 is stored in the main board storage case 25.

  When removing the storage medium dedicated substrate 32 from the substrate body 34, first, the lid 25b of the main substrate storage case 25 is unlocked and opened. Then, the portion exposed from the second hole 34 c of the string 39 or the storage medium dedicated substrate 32 is picked and the string 39 is pulled. By pulling the string 39 in this way, the rib 40b is broken. As a result, the storage medium dedicated substrate 32 can be pulled out from the connection connector 35. At this time, since the remains of the ribs 40b remain in the through holes 38c, it is possible to easily and reliably know that the storage medium dedicated substrate 32 has been removed from the substrate body 34 by visually checking the remains. Thereby, the act of removing the storage medium dedicated substrate 32 from the substrate main body 34 illegally can be prevented.

  When removing the storage medium dedicated substrate 32 from the substrate body 34, the string 39 may be cut without pulling the string 39 or the storage medium dedicated substrate 32. By cutting the string 39, a trace of the cut remains on the string 39. By visually checking this trace, it can be known that the storage medium dedicated substrate 32 has been removed from the substrate body 34.

  Further, since the storage medium dedicated substrate 32 is prevented from being pulled out of the connection connector 35 by the pull-out preventing member 36 without using an adhesive, the recyclability of the storage medium dedicated substrate 32 and the substrate body 34 is improved. be able to.

However, as shown in FIG. 10, the base member 37 corresponds to the first hole 34b. A through hole 38g may be formed on the base body 37. When the base member 37 is attached to the substrate body 34, the top surface 38a is disposed so as to face the back surface 34d of the substrate body 34, and the through hole 38g is formed as the first hole. The base member 37 may be fixed to the back surface 34d of the substrate body 34 with an industrial adhesive or a screw while aligning the through hole 38c with the position of the second hole 34c at the position 34b. Then, after the locking member 43 is inserted through the second hole 34c and the through hole 32b, the locking member 43 and the through hole 38g are arranged so as to face each other via the first hole 34b. Is inserted through the through hole 38g. As a result, as in the above embodiment, the locking member 43 engages with the edge 38e so that the locking member 43 cannot be removed in the direction opposite to the insertion direction, and the tip 39b side of the string 39 is separated into the base member 37. Linked impossible.

  In the above embodiment, the through hole 41a is formed in the protrusion 41. However, the present invention is not limited to this, and a bottomed cylindrical protrusion 46 may be formed as shown in FIG. A hole 46a is formed in the protrusion 46, and a groove (locking portion) 46c into which the locking piece 43b is fitted is formed in the inner peripheral wall surface 46b of the hole 46a. By inserting the locking member 43 into the hole 46a, the locking piece 43b of the locking member 43 is locked in the groove 46c in a non-detachable state in the direction opposite to the insertion direction. Thereby, the front end 39b side of the string 39 is connected to the base member 37 so as not to be separated.

  In the above embodiment, the locking member 43 is formed at the tip 39b of the string 39, and the through hole 41a through which the locking member 43 is inserted is formed in the protrusion 41. However, as shown in FIG. 47, a bottomed cylindrical fitting member 48 may be provided at the tip 39b of the string 39. The locking projection 47 has the same configuration as that of the locking member 43 described above, and includes a shaft 47a and a locking piece 47b. The fitting member 48 has the same configuration as the protrusion 41 described above, and has a hole 48a. A groove 48c is formed in the inner peripheral wall surface 48b of the hole 48a. When attaching the base member 37 to the substrate body 34, the locking projection 47 is inserted through the first hole 34b. After the locking protrusion 47 and the hole 48a are arranged to face each other through the first hole 34b, the locking protrusion 47 is inserted into the hole 48a, whereby the locking piece 47b of the locking protrusion 47 is inserted into the groove 48c. Lock in a non-removable state in the direction opposite to the insertion direction. Thereby, the front end 39b side of the string 39 is connected to the base member 37 so as not to be separated.

  In the above embodiment, the tip 39b of the cord 39 is inserted into the second hole 34c and the through-hole 32b in this order, and then the locking member 43 is inserted into the through-hole 41a so that the tip 39b side of the cord 39 is separated into the base member 37. For example, a notch is formed in the upper portion of the storage medium dedicated substrate 32, and the strap 39 is passed through the notch from the edge of the substrate body 34 so that the locking member 43 is attached. You may make it insert in the through-hole 41a. In this case, when the locking member 43 is engaged with the edge 38e, the length of the string 39 is adjusted in advance so that the string 39 does not loosen. Thereby, the same effect as the above-mentioned embodiment can be given.

  In the above-described embodiment, the example in which the present invention is applied to the main board 24 has been described. However, the present invention is not limited to this and can be applied to a sub-board for controlling the operation of a speaker or a lamp. . In the slot machine 10, there is a control that the winning conditions are not satisfied unless the first to third stop buttons 19a to 19c are pressed in the correct order even if the electronic lottery is won, and the ROM mounted on the sub board is illegal. If the first to third stop buttons 19a to 19c are inadvertently notified by a speaker or a lamp, the first to third stop buttons 19a to 19c are pressed accordingly. There is a risk that medals may be obtained illegally. Therefore, by applying the present invention to the sub board, it is possible to prevent an illegal act such as removing the ROM from the sub board.

  Next, a second embodiment will be described with reference to FIGS. Hereinafter, the same reference numerals are assigned to the same members as those in the first embodiment described above, and the description thereof is omitted. As shown in FIGS. 13 and 14, the main board 50 includes a storage medium dedicated board 32 and a board body (first board) 51. Various circuit components such as the storage medium dedicated substrate 32 and the CPU 33 are mounted on the mounting surface (front surface) 51 a of the substrate body 51. The mounting surface 51 a is provided with a connection connector 35 in which an insertion port 35 a is formed. By inserting the terminal 32 a of the storage medium dedicated substrate 32 into the connection connector 35, the storage medium dedicated substrate 32 is attached to the substrate body 51. In this state, the storage medium dedicated substrate 32 and the substrate body 51 are electrically connected.

  The base member 53 is formed in a long thin plate shape. One end of the base member 53 is integrally formed with a bent portion 54 that is bent so as to partially wrap one end edge of the substrate body 51. The bent portion 54 rises from one end of the base member 53 at a height similar to the thickness of the substrate body 51, and the upper surface 53a of the base member 53 extends from the rising portion 54a toward the other end of the base member. It consists of a folded portion 54b extending so as to be substantially parallel. Further, a substantially cylindrical protrusion (tubular portion) 55 protruding in the same direction as the rising portion 54a is integrally formed on the upper surface 53a. The protrusion 55 is formed to correspond to the first hole 51b. When the projection 55 is pushed into the first hole 51b, it is pressed and held. A through hole 55 a that penetrates the base member 53 is formed in the central portion of the protrusion 55 in the axial direction.

  When the base member 53 is attached to the substrate body 51, the base member 53 is disposed on the back surface 51c side of the substrate body 51 so that the upper surface 53a faces the back surface 51c of the substrate body 51, and the base member 53 and the rising portion 54a are folded back. The base member 53 is attached to the substrate body 51 by wrapping one end edge of the substrate body 51 with the portion 54b and press-fitting the protrusion 55 into the first hole 51b.

  An inclined surface 54c rising from the front end portion in the extending direction of the folded portion 54b is formed. The inclined surface 54c is formed on the other end of the base member 53 with the base member 53, the rising portion 54a and the folded portion 54b wrapping one end edge of the substrate body 51 around the tip of the folded portion 54b with respect to the mounting surface 51a. It is formed so as to incline approximately 45 degrees toward the end side. Thereby, when it sees from the mounting surface 51a side, the inclined surface 54c can be easily visually recognized. Note that the inclined surface 54c only needs to be formed so as to be visible when viewed from the mounting surface 51a side, and the inclination angle may be set appropriately.

  A through hole 54d is formed in the inclined surface 54c. The through hole 54d is provided with a fixing portion 40. The fixing portion 40 is formed on the mounting surface 51a when the base member 53, the rising portion 54a, and the folded portion 54b wrap one end edge of the substrate body 51. Exposed. The folded portion 54b is provided with a surface 54e inclined from the upper end of the inclined surface 54c toward the rising portion 54a, and an opening 54f communicating with the through hole 54d is formed in the surface 54e. By this opening 54f, it is possible to improve the visibility when the inspection is performed by peeping into the fixing portion 40 from the side surface of the main substrate storage case 25.

  The fixing portion 40, the base member 53, and the bent portion 54 are made of plastic, and these are integrally formed. The fixing portion 40 includes a fixing portion main body 40a positioned at the center of the through hole 54d, and a plurality of thin rod-like ribs 40b that support the fixing portion main body 40a. The ribs 40b are formed radially from the side peripheral surface 40c of the fixed portion main body 40a to the inner peripheral wall surface 54g of the through hole 54d, and are connected so that the fixed portion main body 40a and the bent portion 54 are integrated.

  A base end 39a of a string 39 having a locking member 43 integrally formed at the tip 39b is fixed to the upper surface 40d of the fixing portion main body 40a. A locking member 43 is provided at the tip 39 b of the string 39 via a connector 42. The locking member 43 includes a shaft 43a and a pair of elastically deformable locking pieces 43b. As described above, the base member 53 is attached so as to overlap the back surface 51c side of the substrate body 51, and after the locking member 43 has been inserted into the through hole 32b and passed through the protrusion 55 through the through hole 55a, By engaging with the edge (locking portion) 53c, the tip 39b side of the string 39 cannot be returned in the direction opposite to the passing direction and is connected to the base member 53 in an inseparable manner.

  A cylindrical accommodating portion 45 that accommodates the locking member 43 in an inaccessible manner is integrally formed on the bottom portion 30 b of the substrate accommodating recess 30. The accommodating portion 45 is formed with a hole 45a. The accommodating portion 45 is formed at a position corresponding to the position of the through hole 55a when the substrate main body 51 to which the pull-out preventing member 52 is attached is accommodated in the main substrate accommodating case 25. The through hole 41a is configured to communicate with the hole 45a when fixed to the screw 44 via a screw (not shown). In the present embodiment, the housing portion 45 is provided in the bottom portion 30b. However, the present invention is not limited to this, and the housing for housing the locking member 43 in an inaccessible manner on the lower surface 53b side of the base member 53 as shown in FIG. The part may be integrally formed.

  Next, the effect | action by the said structure is demonstrated. When the main substrate 50 is stored in the main substrate storage case 25 (see FIG. 3), first, the back surface 51c of the substrate body 51 and the upper surface 53a of the base member 53 face each other, and the protrusion 55 corresponds to the first hole 51b. At the same time, the base member 53 is disposed on the back surface 51c side of the substrate body 51 so that the bent portion 54 is positioned at the edge of the substrate body.

  Next, after the protrusion 55 is press-fitted into the first hole 51 b from the back surface 51 c side, the base member 53 is bent so that the upper surface 53 a of the base member 53 is separated from the back surface 51 c of the substrate body 51 by gripping the bent portion 54. The base member 53, the rising portion 54a, and the folded portion 54b wrap the one end edge of the substrate body 51 while releasing the bending. Thereby, the base member 53 is detachably attached to the substrate body 51. Further, the fixing portion 40 provided in the bent portion 54 is exposed on the mounting surface 51a. Thus, when the adhering portion 40 is exposed on the mounting surface 51a, when the rib 40b is broken, the broken trace can be easily confirmed. Note that the base member 53 can be easily attached to the substrate body by thinning at least a part of the rising portion 54a and making the bent portion 54 easily bent.

  Before or after the base member 53 is attached to the substrate body 51, the terminal 32 a of the storage medium dedicated substrate 32 is inserted into the connection connector 35 of the substrate body 51. Then, the substrate main body 51 is placed on the support column 44 and fixed with screws while positioning so that the through hole 55a communicates with the hole 45a of the accommodating portion 45.

  Next, the locking member 43 is inserted into the through hole 32 b of the storage medium dedicated substrate 32. After the locking member 43 is inserted into the through hole 32b, the locking member 43 is disposed so as to face the through hole 55a, and the locking member 43 is inserted into the through hole 55a.

  When the locking member 43 is inserted into the through hole 55a, the locking piece 43b contacts the inner peripheral wall surface of the through hole 55a, and the locking piece 43b is elastically deformed from the engageable position to the insertable position. When the locking member 43 passes through the through hole 55a, the locking piece 43b engages with the edge 53c. As a result, the tip 39b side of the string 39 cannot be returned in the direction opposite to the aforementioned passing direction, and the base member 53 is connected to the base member 53 in an inseparable manner.

  Further, since the locking member 43 is housed in the housing portion 45 and is brought into a non-contactable state, there is no possibility that the locking member 43 is broken or that the locking member 43 is crafted. Further, since the accommodating portion 45 supports the edge 53c, when the locking member 43 is inserted into the through hole 55a, the locking member 43 penetrates without dropping the protrusion 55 press-fitted into the first hole 51b. It can be smoothly inserted into the hole 55a.

  After the main board 24 is thus housed in the case body 25a, the lid 25b is closed and locked. Through the above process, the main board 24 is stored in the main board storage case 25.

  When removing the storage medium dedicated substrate 32 from the substrate body 34, first, the lid 25b of the main substrate storage case 25 is unlocked and opened. Then, the base end 39a of the string 39 is picked and pulled, or the storage medium dedicated substrate 32 is picked and the string 39 is pulled. By pulling the string 39 in this way, the rib 40b is broken. As a result, the storage medium dedicated substrate 32 can be pulled out from the connection connector 35. At this time, since the remains of the ribs 40b remain in the through holes 54d, it is possible to easily and reliably know that the storage medium dedicated substrate 32 has been removed from the substrate body 51 by visually checking the remains. Moreover, since the adhering portion 40 is exposed on the mounting surface 51a, the remnants of the rib 40b can be easily confirmed.

  In the above embodiment, the locking piece 43b of the locking member 43 is engaged with the edge 53c. However, the present invention is not limited to this, and a groove (locking portion) is formed in the protrusion 55, and the locking member 43 is formed. Is inserted into the through hole 55a, the engaging piece 43b may be engaged with the groove.

  In the above embodiment, the protrusion 55 is press-fitted into the first hole 51b from the back surface 51c side, and the base member 53 is wrapped around the one end edge of the substrate body 51 by the base member 53, the rising portion 54a, and the folded portion 54b. However, it is also possible to attach the base member 53 to the substrate body 51 using only the protrusions 55. Further, the base member 53 can be attached to the substrate body 51 by wrapping one end edge of the substrate body 51 with the base member 53, the rising portion 54a, and the folded portion 54b without using the protrusion 55.

  In the above embodiment, the base member 53, the rising portion 54a, and the folded portion 54b wrap one end edge of the substrate body 51. However, the base member 53 and the folded portion 54b may sandwich the substrate body 51. .
