Description

  The present invention relates to a board unit provided in a gaming machine such as a pachinko machine or a slot machine.

  Various control boards for controlling games are provided in gaming machines such as pachinko machines and slot machines, and this control board is used to specify “name of the manufacturer of the gaming machine” and “type of the board”. "Numbers, symbols and other codes" are required to be printed. Normally, this type of control board is configured as a board unit by being housed in an upper case and a lower case, and this board unit is detachably attached to the back surface of the gaming machine or inside the housing.

  In recent years, sharing of parts has been promoted in the field of gaming machines. For example, by using one type of control board in common for pachinko machines for Company A and Company B, the manufacturing cost of the board has been reduced. Attempts have been made to try. In this case, since it is necessary to print the name of the corresponding manufacturer and the type identification mark on the control board, even if the circuit configuration mounted on the board can be shared, the manufacturer identification mark and type identification of company A It is necessary to separately manufacture and manage the substrate on which the sign is printed and the substrate on which the manufacturer identification mark and the type identification mark of company B are printed. Therefore, despite the fact that the control boards have the same control contents, there has been a problem that it is difficult to significantly reduce the manufacturing cost and the parts management becomes complicated.

  Therefore, conventionally, a plurality of identification mark display parts connected to each other at the corners of the substrate main body via a cutting part are provided, and different identification signs (for example, for company A) indicating the manufacturer name and the like are provided on each of the identification mark display parts. And for the company B), and by cutting the remaining cut portion from the substrate main portion except for one cut portion, only one arbitrary identification mark display portion is left integrally on the substrate main portion. A control board has been proposed (see, for example, Patent Document 1). In the control board configured as described above, if the identification mark display portion on which the identification mark of company A is displayed is cut and removed, the control board for B company is obtained, and the identification sign display on which the identification mark of company B is displayed. If the part is cut and removed, it becomes a control board for company A, so only one type of control board with the same circuit components is manufactured, and the control board is supplied to two different manufacturers. be able to.

This IC tag includes a long antenna extending along a diagonal line of a base sheet and an IC chip disposed near the center of the antenna, and unique identification information stored in the IC chip is read by a reader. It can be read. Note that the base sheet of the seal seal 110 can be easily broken using fingers, and the IC tag is also cut simultaneously by breaking the base sheet.

  Further, an upper seal cover 111 and a lower seal cover 112 are fixed so as to cover the sealing seal 110 with respect to the substrate case 101, whereby both cases 103 and 104 are sealed in a state in which the control substrate 105 is accommodated. The flat upper seal cover 111 is made of a transparent resin molded product, and the upper seal cover 111 is fixed to the seal mounting portion 103a of the upper case 103 by ultrasonic welding. The upper seal cover 111 is formed with an easily excisable portion 111a, and the easily excisable portion 111a is formed in a shape in which a cross-shaped crosspiece is continuous with the inner peripheral surface of the circular hole. When the upper seal cover 111 is ultrasonically welded to the seal mounting portion 103a, the excisable portion 111a is positioned directly above the through hole 103b. On the other hand, the lower seal cover 112 has an L-shaped cross section, and the lower seal cover 112 is also fixed to the lower case 104 by ultrasonic welding.

  Next, the fixed base 102 will be described. As shown in FIGS. 5 and 12, the fixed base 102 includes a vertically long support body 113 firmly attached to the back surface of the game board 7, and an upper portion of the support body 113. It is comprised with the movable body 115 fixed to the side surface using the crimping pin 114. FIG. Three attachment holes 113a are formed in a line along the vertical direction on the upper front surface of the support body 113, and the arrangement pitch (interval) of these attachment holes 113a is equal to the arrangement pitch of the positioning grooves 104d of the lower case 104 described above. Are set the same. In addition, a plurality of company names indicating “names of manufacturers of pachinko machines (game machines)” are engraved on the upper front surface of the support body 113 as fixed-side identification mark portions 116. It is formed close to the side of the mounting hole 113a. Each company name of the fixed side identification mark portion 116 corresponds to the first identification mark portion 106 of the control board 105. In the case of the present embodiment example, “XX company” is placed on the side of the uppermost mounting hole 113a, and the center. “△△ Company” is stamped on the side of the mounting hole 113a, and “XX Company” is stamped on the side of the lowermost mounting hole 113a. On the other hand, a notch 117 is formed on the upper side surface of the support body 113, and the notch 117 has a slit 117a extending in the vertical direction. Further, a positioning hole 118 is formed on the lower side surface of the support body 113, and the positioning projection 104 b of the lower case 104 is inserted into the positioning hole 118.

  The movable body 115 includes a front plate 115a and a rear plate 115b facing in the front-rear direction, and a rectangular side plate portion 115c that connects the front plate 115a and the rear plate 115b. The front plate 115a is formed in the slit 117a. It is inserted so that it can move up and down. A holding hole 119 is formed in the front plate 115a, and the holding hole 119 can be selectively aligned with one of the mounting holes 113a by moving the front plate 115a up and down along the slit 117a. It has become. Then, with the holding hole 119 aligned with the arbitrary mounting hole 113a, the caulking pin 114 is inserted into the mounting hole 113a from the front of the support body 113, and the tip of the caulking pin 114 is fitted into the holding hole 119. As a result, the mounting position of the movable body 115 with respect to the support main body 113 can be changed to a plurality of positions (three positions in this embodiment). Since the tip of the caulking pin 114 is formed in an arrowhead shape, the caulking pin 114 fitted in the holding hole 119 cannot be extracted from the mounting hole 113a unless the head of the caulking pin 114 is destroyed. Further, since the company name of the fixed side identification mark portion 116 is engraved on the side position of each mounting hole 113a, by visually observing the head of the caulking pin 114 that covers the mounting hole 113a and the company name on the side, It is possible to instantly determine whether it is a fixed base 102 for the company.

  A round hole-shaped keyhole 120 is formed in the side plate portion 115 c of the movable body 115, and the key portion 108 b of the blindfold plate 108 protruding from the substrate case 101 is inserted into the keyhole 120. However, the distance between the key hole 120 and the positioning hole 118 in the fixing base 102 matches the distance (L1, L2, L3) between the key portion 108 of the substrate case 101 to be attached to the fixing base 102 and the positioning projection 104b. If not, the key portion 108b of the blind plate 108 cannot be inserted into the key hole 120 of the movable body 115. In this case, the board case 101 cannot be attached to the fixed base 102.

  A case will be described in which one of a plurality of manufacturer names, for example, a substrate case 101 for “XX” is manufactured using the blindfold plate 108 as described above. First, the control board 105 is fixed inside the upper case 103 using screws (not shown), and the main body part 108a of the blindfold plate 108 is mounted at the lowest position of the mounting part 104a of the lower case 104, and the key part 108b. Is protruded outward from the upper portion of the lower case 104 with the least amount of protrusion. Next, the upper case 103 and the lower case 104 are overlapped by slide fitting (see FIG. 10), and the protrusion 105a of the control board 105 fixed to the upper case 103 is placed on the lower case 104 as shown in FIG. It inserts in the space between the part 104a and the main-body part 108a. As a result, as shown in FIG. 11A, one of the plurality of company names “XX” of the first identification marker 106 is exposed from the window hole 108c of the blindfold plate 108, and the remaining two company names “ΔΔ”. And “XX” are concealed by the main body 108a. At this time, the distance between the positioning projection 104b formed on the side surface of the lower case 104 and the key portion 108b of the blindfold plate 108 is the minimum value L1.

  Next, the upper case 103, the lower case 104, and the blindfold plate 108 are integrated using the screws 109, and then the sealing seal 110 is attached to the seal mounting portion 103 a of the upper case 103 and the back surface of the lower case 104 from above the screws 109. (See FIG. 7). After that, the upper seal cover 111 and the lower seal cover 112 are covered from above the seal seal 110, and both the seal covers 111 and 112 are ultrasonically welded and fixed to the corresponding cases 103 and 104 (see FIG. 5). Thus, the sealing of the substrate case 101 (the upper case 103 and the lower case 104) is completed, and only the company name “XX” exposed in the window hole 108c of the blindfold plate 108 in this state is visually observed through the transparent upper case 103. Therefore, the board case 101 is manufactured as a board case containing a control board 105 for “XX” company.

  In order to attach the substrate case 101 manufactured in this way to the fixing base 102, the fixing base 102 is also a fixing base for “XX” company, that is, a blindfold plate protruding to the side of the substrate case 101. The key portion 108b and the positioning protrusion 104b of 108 must be able to be inserted into the key hole 120 and the positioning hole 118 of the fixed base 102, respectively. In order to manufacture the fixed base 102 for “XX” company, the movable body 115 is moved up and down along the slit 117a of the support body 113, and the mounting hole 119 is attached at a position where it coincides with the lowermost mounting hole 113a. The caulking pin 114 may be inserted into the hole 113a and the tip of the caulking pin 114 may be fitted into the holding hole 119. As a result, as shown in FIG. 5, since the movable body 115 is fixed to the support body 113 at the lowermost mounting position, the distance between the key hole 120 and the positioning hole 118 in the fixing base 102 is It becomes equal to the distance L1 between the key part 108 and the positioning protrusion 104b, and this fixed base 102 becomes a fixed base for "XX" company. Therefore, by inserting the key portion 108b and the positioning protrusion 104b of the substrate case 101 manufactured for the “XX” company into the key hole 120 and the positioning hole 118 of the fixing base 102 for the “XX” company, respectively. As shown in FIG. 4, a substrate unit 100 for “XX” company in which a substrate case 101 is attached to a fixed base 102 can be obtained.

  In order to obtain the substrate unit 100 for the “ΔΔ” company, it is necessary to manufacture the substrate case 101 for the “ΔΔ” company and the fixed base 102 for the “ΔΔ” company. When manufacturing the substrate case 101 for “△△” company, the main body portion 108a of the blindfold plate 108 is mounted at an intermediate position of the mounting portion 104a of the lower case 104, and as shown in FIG. It is only necessary to expose “ΔΔ” in the window hole 108 c of the plate 108 and set the distance between the key portion 108 b and the positioning projection 104 b to an intermediate value L 2. Otherwise, the substrate case 101 for “XX” company is used. Is the same as the case of manufacturing. On the other hand, with respect to the fixed base 102, when the caulking pin 114 is inserted into the middle mounting hole 113a and fitted into the holding hole 119 of the movable body 115, the movable body 115 is fixed to the support body 113 at an intermediate mounting position. As a result, the distance between the key hole 120 and the positioning hole 118 becomes equal to the distance L2 between the key portion 108 and the positioning projection 104b in the substrate case 101, so that the fixing base 102 is a fixing base for “ΔΔ” company. . Therefore, by inserting the key part 108b and the positioning protrusion 104b of the board case 101 manufactured for the “ΔΔ” company into the key hole 120 and the positioning hole 118 of the fixing base 102 for the “ΔΔ” company, respectively. Thus, the substrate unit 100 for “ΔΔ” in which the substrate case 101 is attached to the fixed base 102 can be obtained.

  Similarly, in order to obtain the substrate unit 100 for the “OO” company, it is necessary to manufacture the substrate case 101 for the “OO” company and the fixed base 102 for the “OO” company. When manufacturing the board case 101 for “XX” company, the main body portion 108a of the blindfold plate 108 is mounted on the uppermost position of the mounting portion 104a of the lower case 104, and as shown in FIG. “XX” is exposed in the window hole 108c of the plate 108, and the distance between the key portion 108b and the positioning projection 104b may be set to the maximum value L3. Otherwise, “XX” and “△△” This is the same as the case of manufacturing the substrate case 101 for use. On the other hand, for the fixed base 102, when the caulking pin 114 is inserted into the uppermost mounting hole 113 a and fitted into the holding hole 119 of the movable body 115, the movable body 115 is at the uppermost mounting position with respect to the support body 113. The distance between the key hole 120 and the positioning hole 118 becomes equal to the distance L3 between the key portion 108 and the positioning projection 104b in the substrate case 101, so that the fixing base 102 is a fixing base for “XX” company. Become. Therefore, by inserting the key part 108b and the positioning protrusion 104b of the board case 101 manufactured for the "OO" company into the key hole 120 and the positioning hole 118 of the fixing base 102 for the "XX" company, respectively. The board unit 100 for “OO” company in which the board case 101 is attached to the fixed base 102 can be obtained.

  As described above, in the substrate unit 100 according to the present embodiment example, one of a plurality of company names printed on the control substrate 105 is selectively selected from the window hole 108c according to the mounting position of the blindfold plate 108 with respect to the substrate case 101. Since one type of control board 105 having the same circuit configuration and the like can be used in common among a plurality of companies, and when manufacturing boards are manufactured individually for each company, In comparison, the total manufacturing cost including parts management can be greatly reduced. In addition, the position of the key portion 108b protruding from the substrate case 101 changes according to the mounting position of the blindfold plate 108, and only the key portion 108b protruding at the normal position is permitted to be inserted into the key hole 120 of the fixing base 102. Therefore, only the substrate case 101 in which the proper company name can be understood can be attached to the fixed base 102, and the security against fraud can be improved. For example, when the control board 105 used for a pachinko machine (game machine) dedicated to “XX” company is reused (reused) for another “△△” company or “XX” company, 101 (upper case 103 and lower case 104) can be opened to change the mounting position of the blindfold plate 108, so that another company name can be exposed in the window hole 108c of the blindfold plate 108. Can be reused.

  Further, by fitting the caulking pin 114 into one of the plurality of mounting holes 113 a provided in the support body 113 of the fixed base 102, the mounting position of the movable body 115 having the keyhole 120 can be changed with respect to the support body 113. Therefore, for example, the fixed base 102 used for the pachinko machine (game machine) dedicated to “XX” company is reused (reused) for another “△△” company or “XX” company. In this case, after the caulking pin 114 is broken and removed from the mounting hole 113a, the mounting position of the movable body 115 is changed and the new caulking pin 114 is fitted into another mounting hole 113a. The fixed base 102 can also be reused. In addition, since the company name corresponding to the first identification mark portion 106 of the control board 105 is displayed on the side of each mounting hole 113a, it is displayed on the head of the pin 114 fitted in the mounting hole 113a and on the side thereof. By visually checking the company name, it is possible to instantly determine which company's fixed base 102 is used.

  In the above embodiment, the control board 105 is provided with a third identification mark part (not shown) separately from the first identification mark part 106 and the second identification mark part 107, Data indicating “management information” may be printed as a QR code (registered trademark) or a barcode, or may be embedded in a substrate as an IC chip. If such a third identification mark portion is provided, a blindfold plate is temporarily provided. Even if 108 is illegally removed from the substrate case 101 and all the company names of the first identification marker 106 are exposed, the management information of the control board 105 can be confirmed from the data of the third identification marker.

  In the above embodiment, the case where the board unit 100 of the present invention is applied to the pachinko machine P has been described, but it is needless to say that the present invention can be applied to other gaming machines such as a slot machine.
