For example, the controller sensor unit includes two transmissive photosensors (parallel sensors) arranged in parallel to the board surface of the game board 2 on the left side of the center position of the operating rod when viewed from the side of the player who faces the pachinko gaming machine 1. Pair) and two transmissive photosensors (vertical sensor pair) arranged perpendicularly to the board surface of the game board 2 on the right side of the center position of the operating rod when viewed from the player's side. The photo sensor may be included.

As a member forming the upper plate, for example, a push button 31B that allows a player to perform a predetermined instruction operation by a pressing operation or the like at a predetermined position on the upper surface of the upper plate main body (for example, above the stick controller 31A). It is provided. The push button 31B may be configured to be able to detect a pressing operation by the player mechanically, electrically, or electromagnetically. A push sensor 35B for detecting a pressing operation by the player performed on the push button 31B may be provided inside the main body of the upper plate at the installation position of the push button 31B.

Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko game machine 1, such as that the game ball that has passed through the passage gate 41 provided in the game area 10 is detected by the gate switch 21 shown in FIG. 2, the ordinary symbol display 20 executes the variable display of the ordinary symbol. After the universal figure starting condition for the is satisfied, for example, the previous universal figure game is finished, based on the universal figure start condition for starting the variable display of the ordinary symbol is established, the ordinary symbol display device The public figure game by 20 is started.

In this public figure game, after the fluctuation of the normal symbol is started, when the predetermined time which is the general figure fluctuation time elapses, the fixed ordinary symbol which is the variable display result of the normal symbol is stopped (displayed). At this time, as a fixed ordinary symbol, if a specific ordinary symbol (a symbol per ordinary symbol) such as a number indicating “7” is stopped and displayed, the variable display result of the ordinary symbol becomes “per symbol”. On the other hand, as the fixed ordinary symbol, for example, if a regular symbol other than the regular symbol, such as a number or a symbol other than the number indicating “7”, is stopped and displayed, the variable display result of the ordinary symbol is “ordinary symbol loss”. Become. In response to the fact that the variable display result of the ordinary symbol is "universal symbol", the expansion opening control (tilt control) is performed in which the movable wing piece of the electric tulip that constitutes the normally variable winning ball device 6B is in the tilted position. When a predetermined time elapses, the normal opening control for returning to the vertical position is performed.

After the first starting condition is satisfied, for example, when the game ball that has passed (entered) the first starting winning opening formed in the normal winning ball device 6A is detected by the first starting opening switch 22A shown in FIG. The special figure game by the first special symbol display device 4A is started based on the fact that the first start condition is satisfied because the previous special figure game or the jackpot gaming state has ended. In addition, the second starting condition is satisfied because the game ball that has passed (entered) the second starting winning opening formed in the normally variable winning ball device 6B is detected by the second starting opening switch 22B shown in FIG. After that, the special figure game by the second special symbol display device 4B is started based on the fact that the second start condition is satisfied, for example, by ending the previous special figure game or the big hit game state.

In the special symbol game by the first special symbol display device 4A and the second special symbol display device 4B, after the variable display of the special symbol is started, when the variable display time as the special symbol variation time elapses, the variable display of the special symbol The finalized special symbol (result of special symbol display) that is the result is derived and displayed. At this time, if a specific special symbol (big hit symbol) is stopped and displayed as the fixed special symbol, it becomes "big hit" as the specific display result, and if a special symbol different from the big hit symbol is stopped and displayed as the fixed special symbol, " It becomes "miss". It should be noted that a predetermined special symbol (small hit symbol) different from the big hit symbol may be stopped and displayed, and when the predetermined special symbol (small hit symbol) is stopped and displayed as a result of the predetermined display. , The small hit game state as a special game state different from the big hit game state may be controlled.

After the variable display result in the special figure game becomes "big hit", the big hit game state is controlled as a specific game state in which a round advantageous to the player (also called "round game") is executed a predetermined number of times.

In the pachinko gaming machine 1 in the present embodiment, as an example, special symbols showing numbers “3”, “5”, and “7” are big hit symbols, and special symbols showing “−” symbols are lost symbols. When the small hit symbol is stopped and displayed, for example, a special symbol indicating the number "2" may be used as the small hit symbol. Incidentally, each symbol such as a big hit symbol and a lost symbol in the special symbol game by the first special symbol display device 4A may be a special symbol different from each symbol in the special symbol game by the second special symbol display device 4B. However, the special symbol common to both special symbol games may be a big hit symbol or a lost symbol.

After the jackpot design showing the numbers "3", "5", and "7" as the fixed special symbols in the special figure game is stopped and displayed as "big hit" as the specific display result, in the jackpot gaming state, the special variable In the period until the special winning opening door of the winning ball device 7 elapses a predetermined upper limit time (for example, 29 seconds or 0.1 seconds) or until a predetermined number (for example, 9) winning balls are generated. , Open the special winning opening. As a result, a round in which the special variable winning ball device 7 is brought into the first state (open state), which is advantageous for the player, is executed.

The special winning a prize sphere device, by receiving the game ball falling on the surface of the game board 2, and then closing the big winning a prize, the big prize award door which opened the big prize award during the execution of the round. 7 is changed to a second state (closed state), which is disadvantageous to the player, and one round is ended. The round, which is the opening cycle of the special winning opening, can be repeatedly executed until the number of times of execution reaches a predetermined upper limit number (for example, "16"). Even before the number of executions of the round reaches the upper limit, the execution of the round may be ended by the establishment of a predetermined condition (for example, a game ball has not been won in the special winning opening). ..

Of the rounds in the big hit game state, the round in which the upper limit time for setting the special variable winning ball device 7 to the first state (open state) advantageous to the player is a relatively long time (for example, 29 seconds) is normally opened. Also called a round. On the other hand, a round in which the upper limit time for setting the special variable winning ball device 7 to the first state (open state) is a relatively short time (for example, 0.1 seconds) is also called a short-term open round.

Incidentally, in the case of displaying the small hit symbol (for example, the number "2"), if these small hit symbols are derived as fixed special symbols, if they are controlled to the small hit game state as the special game state. good. Specifically, in the small hitting game state, for example, like the above-mentioned short-term open big hitting state in which a ball (prize ball) is not substantially obtained, the special variable winning ball device 7 has a big winning opening which is advantageous to the player. It suffices to execute the variable winning operation for changing to the first state (open state).

In the "left", "middle", and "right" effect symbol display areas 5L, 5C, and 5R provided in the effect display device 5, the special symbol game using the first special symbol on the first special symbol indicator 4A and In the special figure game using the second special figure on the second special symbol display device 4B, in response to the start of one of the special figure games, the variable display of the effect symbols is started. Then, the period from the start of the variable display of the effect symbols to the end of the variable display due to the stop display of the fixed effect symbols in each of the "left", "middle" and "right" effect symbol display areas 5L, 5C, 5R. Then, the variable display state of the effect design may be a predetermined reach state.

Here, the reach state, the effect design which is stopped and displayed when the effect design stopped and displayed in the display area of the effect display device 5 constitutes a part of the big hit combination (“reach variation pattern”). (Also referred to as) is a display state in which the fluctuation continues, or a display state in which all or some of the effect symbols are changing in synchronization while forming all or part of the big hit combination. Specifically, in some of the "left", "middle", and "right" effect symbol display areas 5L, 5C, 5R (eg, "left" and "right" effect symbol display areas 5L, 5R etc.) The remaining effect symbol display area (for example, "Medium" effect) that is not yet stopped and displayed when the effect symbol (for example, the effect symbol indicating the alphanumeric character "7") that constitutes the determined jackpot combination is stopped and displayed. In the display state where the effect symbols are changing in the symbol display area 5C or the like, or the effect symbol is a big hit in all or part of the effect symbol display areas 5L, 5C, 5R of "left", "middle" and "right" It is a display state in which all or part of the combination is changed while changing in synchronization.

Further, in response to the reach state, the fluctuation speed of the effect design is reduced, or a character image (effect image imitating a person or the like) different from the effect design is displayed in the display area of the effect display device 5. By changing the display mode of the background image, playing back and displaying a moving image different from the effect design, or changing the variation mode of the effect design, a different effect operation from before the reach state is executed. May be done. The production operation such as the display of the character image or the display mode of the background image, the reproduction display of the moving image, and the change of the variation mode of the production design is referred to as reach production display (or simply reach production). In addition, in the reach effect, not only the display operation in the effect display device 5, but also the voice output operation by the speakers 8L and 8R, the lighting operation (flashing operation) in the light-emitting body such as the game effect lamp 9, and the like are put in the reach state. It may be included in an operation mode different from the previous operation mode.

As the effect operation in the reach effect, a plurality of kinds of effect patterns (also referred to as “reach patterns”) having different operation modes (reach modes) may be prepared in advance. And, the possibility of becoming a "big hit" (also called "reliability" or "big hit reliability") is different in each reach mode. That is, it is possible to change the possibility that the variable display result is a “big hit” depending on which of a plurality of types of reach effects is executed.

As a fixed special symbol in the special symbol game, when a special symbol that is a lost symbol is stopped (derived), the variable display state of the effect symbol is not changed to the reach state after the variable display of the effect symbol is started. In some cases, a fixed effect symbol that is a predetermined non-reach combination may be stopped and displayed. Such a variable display mode of effect symbols is referred to as a “non-reach” (also referred to as “normal loss”) variable display mode when the variable display result is “miss”.

As a fixed special symbol in the special figure game, when the special symbol that is the lost symbol is stopped (derived), the variable display state of the effect symbol is started after the variable display of the effect symbol is started. Correspondingly, after the reach effect is executed, or the reach effect is not executed, the fixed effect symbol forming a predetermined reach-miss combination may be stopped and displayed. The variation display result of such effect symbols is referred to as a variation display mode of "reach" (also referred to as "reach loss") when the variation display result is "miss".

As a confirmed special symbol in the special symbol game, when the big hit symbol showing the number "3" among the special symbols which is the big hit symbol is stopped and displayed, it corresponds to the variation display state of the effect symbol being the reach state. Then, after the predetermined reach effect is executed, the fixed effect symbol which is the predetermined normal big hit combination (also referred to as "non-probable variation big hit combination") of the plurality of kinds of big hit combinations is stopped and displayed. Incidentally, the reach effect may not be executed, and the non-probable variation big hit combination may be stopped and displayed as the finalized effect design.

The fixed effect symbols that are usually the jackpot combination (non-probable variation jackpot combination) are variably displayed in the effect symbol display areas 5L, 5C, and 5R of "left", "middle", and "right" in the effect display device 5, for example. Of the effect symbols with the symbol numbers “1” to “8”, any one of the effect symbols with the symbol numbers “2”, “4”, “6”, “8” is “left”, “ It suffices as long as it is stopped and displayed in line on a predetermined effective line in each of the effect symbol display areas 5L, 5C, 5R of "middle" and "right". The effect symbols having the even number "2", "4", "6", and "8" that constitute the normal jackpot combination are called normal symbols (also referred to as "non-probability variation symbols").

Corresponding to the fact that the fixed special symbol in the special figure game becomes the normal big hit symbol, after the predetermined reach effect is executed, the fixed effect symbol of the normal big hit combination (non-probable variation big hit combination) is displayed as a stop. The variable display mode is referred to as a “non-probable variation” (also called “normal big hit”) variable display mode (also called “big hit type”) when the variable display result is “big hit”. Alternatively, the normal big hit combination (non-probable variation big hit combination) may be stopped and displayed as the finalized effect design without executing the reach effect. Based on the fact that the variation display result is "big hit" in the "non-probable change" big hit type, the normal open big hit state is controlled, and after the end, the time reduction control (time saving control) is performed. By performing the time saving control, the variable display time of the special symbol in the special figure game (special figure change time) is shortened as compared with the normal state. Incidentally, in the time saving control, as will be described later, the winning frequency of the ordinary symbol is increased, and the winning frequency to the ordinary variable winning ball device 6B is increased, so-called Den Chu support is implemented. Here, the normal state is a normal game state different from a specific game state such as a big hit game state, and an initial setting state of the pachinko gaming machine 1 (for example, when the system is reset, after power-on). The same control as the state in which the initialization process is executed) is performed. In the time saving control, one of a condition that the special figure game is executed a predetermined number of times (for example, 100 times) after the jackpot gaming state is ended and that the variable display result is “big hit” is established first. Sometimes you just need to quit.

As a confirmed special symbol in the special symbol game, if the probability variation big hit symbol such as a special symbol indicating the numbers “5” and “7” among the special symbols to be the big hit symbol is stopped and displayed, the variable display state of the effect symbol In response to the fact that the reach state is reached, after the reach effect similar to the case where the variation display mode of the effect design is "normal" is executed, among the plurality of kinds of jackpot combinations, a predetermined probability variation jackpot combination There is a case where the finalized effect design is stopped and displayed. Incidentally, the reach effect may not be executed, and the probability variation big hit combination may be stopped and displayed as the finalized effect design. The fixed effect symbol combination which is the probability variation big hit combination, for example, the symbol number that is variably displayed in each of the effect symbol display areas 5L, 5C, 5R of "left", "middle" and "right" in the effect display device 5 is "1". ~ Of the effect symbols of "8", the effect symbol having the symbol number "7" is a predetermined effective line in each of the effect symbol display areas 5L, 5C, 5R of "left", "middle", and "right". It is sufficient if they are displayed in a stop at the same time. The effect symbol having the symbol number "7" which constitutes the probability variation big hit combination is referred to as a probability variation symbol. When the probability variation big hit symbol is stopped and displayed as the fixed special symbol in the special drawing game, the fixed effect symbol which is usually the big hit combination may be stopped and displayed as the variable display result of the effect symbol.

Regardless of whether the fixed effect symbol is the normal big hit combination or the probability variation big hit combination, the variation display mode in which the probability variation big hit symbol is stopped and displayed as the fixed special symbol in the special figure game is a variation display result of "big hit". In this case, it is referred to as a “probable change” variation display mode (also referred to as “big hit type”). In the present embodiment, of the "probable variation" jackpot types, "5" and "7" as the confirmed special symbols are displayed as "big hits" in the variable display results, and the normal open jackpot state is controlled. After that, stochastic variation control (probability variation control) is performed together with time saving control.

By performing these probability variation controls, the probability that the variable display result (special figure display result) is a "big hit" in each special figure game is improved to be higher than in the normal state. The probability variation control may be terminated when the condition that the variable display result becomes "big hit" and the big hit game state is controlled again after the big hit game state ends. As with the time saving control, when the special figure game is executed a predetermined number of times (for example, 100 times the same as the time saving number or 90 times different from the time saving number) after the jackpot gaming state ends, the probability variation control ends. May be. In addition, even if the probability variation control is ended when "probability variation falling" is determined to end the probability variation control in the probability variation falling lottery that is executed each time the special figure game is started after the end of the jackpot gaming state. Good.

When the time saving control is performed, the control for making the variation time of the ordinary symbol in the ordinary figure game by the ordinary symbol display device 20 (the ordinary figure variation time) shorter than that in the normal state, or the variation of the ordinary symbol in each ordinary figure game Control for improving the probability that the display result is "Public hit" compared to that in the normal state, tilt control of the movable wing piece in the ordinary variable winning ball device 6B based on that the variation display result is "Public hit" In order to make it easier for the game ball to pass (enter) through the second start winning port, such as control for making the tilt control time for performing longer than in the normal state and control for increasing the number of tilts than in the normal state By increasing the possibility that the starting condition is satisfied, a control (electricity chewing support control) that is advantageous to the player is performed. In this way, the control that makes it easier for the player to enter the game ball into the second start winning port along with the time saving control is also referred to as high opening control. As the high opening control, any one of these controls may be performed, or a plurality of controls may be combined and performed.

By performing the high opening control, the frequency of the second starting winning opening being in the expanded opening state is increased as compared with the case where the high opening control is not performed. As a result, the second starting condition for executing the special figure game using the second special figure on the second special symbol display 4B is easily established, and the special figure game can be executed frequently. In addition, the time until the variable display result becomes "big hit" is shortened. The period during which the high opening control can be executed is also referred to as a high opening control period, and this period may be the same as the period during which the time saving control is performed.

The game state in which both the time saving control and the high opening control are performed is also called a time saving state or a high base state. The gaming state in which the probability variation control is performed is also referred to as a probability variation state or a highly accurate state. The gaming state in which the time saving control and the high opening control are performed together with the probability variation control is also referred to as a highly accurate high base state. Although not set as a controlled game state in the present embodiment, a certain variation state in which only certain variation control is performed and time saving control or high opening control is not performed is also referred to as a highly precise low base state. Further, only the gaming state in which the time reduction control and the high opening control are performed together with the probability variation control may be referred to as a "probability variation state" in particular, and may be referred to as a time reduction probability variation state in order to distinguish it from the highly accurate low base state. On the other hand, the certainty variation state in which only the certainty variation control is performed and neither the time saving control nor the high opening control is performed (highly accurate low base state) is sometimes referred to as the no time saving certainty variation state in order to distinguish it from the highly accurate high base state. The time saving state in which the time saving control or the high opening control is performed without performing the probability variation control is also referred to as a low accuracy high base state. The normal state in which neither the probability variation control, the time saving control, nor the high opening control is performed is also referred to as a low accurate low base state. When at least one of time saving control and probability variation control is performed in a game state other than the normal state, the special figure game can be frequently executed, and the probability that the variable display result in each special figure game is a "big hit" As a result, the player is in an advantageous state. A gaming state that is advantageous to the player and different from the jackpot gaming state is also called a special gaming state.

In the case of displaying the small hit symbol in a stopped state, after controlling the small hit game state as described above, the game state is not changed, and the variation display result becomes the "small hit" before the game state. It should be controlled continuously.

Next, the operation (action) of the pachinko gaming machine 1 in this embodiment will be described. In the main board 11, when power supply from a predetermined power supply board is started, the game control microcomputer 100 is activated, and the CPU 103 executes predetermined processing which is game control main processing. When the game control main process is started, the CPU 103 makes necessary initialization after setting interrupt prohibition. In this initial setting, the RAM 102 is cleared, for example. In addition, register setting of CTC (counter/timer circuit) built in the game control microcomputer 100 is performed. Thereby, thereafter, the interrupt request signal is sent from the CTC to the CPU 103 every predetermined time (for example, 2 milliseconds), and the CPU 103 can periodically execute the timer interrupt process. When the initial setting is completed, the interrupt is permitted and then the loop processing is started. In the game control main process, a process for returning the internal state of the pachinko gaming machine 1 to the state at the time when the power supply was stopped last time may be executed, and then the loop process may be started.

When the CPU 103 that has executed the game control main process receives the interrupt request signal from the CTC and accepts the interrupt request, it executes the game control timer interrupt process. When the game control timer interrupt process is started, the CPU 103 first executes a predetermined switch process to perform a gate switch 21, a first starting port switch 22A, a second starting port switch 22B, a count through the switch circuit 110. The state of the detection signal input from various switches such as the switch 23 is determined. Then, by executing a predetermined main-side error process, an abnormality diagnosis of the pachinko gaming machine 1 is performed, and a warning can be issued if necessary according to the diagnosis result. After that, by executing a predetermined information output process, data such as big hit information, start information, and probability variation information supplied to a hall management computer installed outside the pachinko gaming machine 1 is output.

Following the information output process, a game random number update process for updating at least a part of the game random numbers such as the random number values MR1 to MR4 used on the main board 11 side by software is executed. After this, the CPU 103 executes special symbol process processing. In the special symbol process processing, the value of the special symbol process flag provided in the game control flag setting unit (not shown) is updated according to the progress of the game in the pachinko gaming machine 1, and the first special symbol display device 4A or the In order to perform the control of the display operation on the 2 special symbol display device 4B and the opening/closing operation setting of the special winning opening in the special variable winning ball device 7, various processes are selected and executed.

Following the special symbol process process, a normal symbol process process is executed.

That is, the air in the inner region surrounded by the outer welding ridges 274 is welded on the imaginary straight line passing through the centers of the outer welding ridges 274 and the inner welding ridges 275 and directed in the left-right direction. Relief passages 276 and 277 are formed to allow escape.

The escape passages 276, 277 have a predetermined width, and are formed at two locations on each of the outer welding ridge 274 and the inner welding ridge 275. Since all of these are arranged on a virtual straight line passing through the center and directed in the left-right direction, the outer welding protrusion 274 and the inner welding protrusion 275 are line-symmetric with respect to the virtual straight line passing through the center and oriented in the left-right direction. It is arranged. The outer welding ridges 274 and the inner welding ridges 275 are formed in a generally triangular shape in vertical cross section which is tapered toward the base-side welding surface 261a (not shown), and the tops thereof contact the base-side welding surface 261a. It is like this.

The cover-side welded portion 223 thus formed is connected to the support plates 270a and 270b extending leftward from the left side wall 202d of the cover member 202 via the connecting portions 280a and 280b. It is provided in. Specifically, the welding plate portion 271 is viewed from the front with respect to the guide piece 282 having a substantially U-shape in a front view, which is formed at a position corresponding to the welding plate portion 271 on the inner wall surfaces of the left side wall 202d and the support plates 270a and 270b. It is arranged so as to be separated by a substantially U-shaped gap S1 (a region surrounded by diagonal lines in FIG. 7A).

The connection part 280a connects the support plate 270a and the welding plate part 271 and the connection part 280b connects the support plate 270b and the welding plate part 271. These connecting portions 280a and 280b extend in a direction orthogonal to the sliding movement direction of the cover member 202 with respect to the base member 201. Further, since the connecting portions 280a and 280b are formed in a plate shape as shown in FIG. 7 and the gap S1 is formed around the connecting portions 280a and 280b, they can be cut by a tool such as a cutter, a nipper, or a saw. ing.

A connecting wall 284 is provided so as to project forward from the right side portion of the welding plate portion 271. Further, a connecting wall 285 that is provided so as to project from the front surface of the guide piece 282 is provided at a position facing the connecting wall 284 with a gap S1 interposed therebetween. The connecting wall 284 and the connecting wall 285 are connected by a connecting tubular portion 286 having a tubular portion, and the insertion piece 264 of the base member 201 is inserted into the connecting wall 285 at a position corresponding to the connecting tubular portion 286. A possible opening 287 is formed. The right side of the connecting tubular portion 286 is open to the front side, and the tip of the insertion piece 264 inserted into the opening 287 can be seen from the front side.

That is, the welding plate portion 271 having the cover-side welding portion 223 has three connecting portions of the connecting portions 280a and 280b and the connecting tubular portion 286 with respect to the main body of the cover member 202 such as the support plates 270a and 270b and the left side wall 202d. Are connected through.

Next, the sealing state of the base member 201 and the cover member 202 will be described. First, as shown in FIG. 3, the main board 11 is attached to the front surface (back surface) side of the cover member 202 via the mounting screws 238. At this time, with the mounting surface 11a of the main board 11 facing the front surface of the cover member 202, the main board 11 is fitted into the cover member 202 for positioning, and mounting screws 238 are attached to the four corners of the main board 11. The cover member 202 is attached to a screw hole (not shown).

In this way, by housing the main substrate 11 on the front side of the cover member 202 so as to cover the mounting surface 11a, even if the cover member 202 is illegally opened, the cover member 202 is accommodated. Unless the main board 11 is removed, the electronic components such as the CPU 103 and the ROM 101 mounted on the mounting surface 11a cannot be fraudulently acted, which is troublesome.

Next, as shown in FIG. 10A, the back surface 11b of the main substrate 11 attached to the front surface side of the cover member 202 is made to face the back surface of the base plate 201a of the base member 201, and the right side wall 201c of the base member 201 is removed. The cover member 202 is brought close to the base member 201 so that the right side wall 202c of the cover member 202 protrudes, and the engagement pieces 220 of the cover member 202 are inserted from the open ends of the engagement grooves 250 of the base member 201. At this time, the right side wall 202c of the cover member 202 covers the outer surface of the side wall 201b of the base member 201, and the side wall 201b of the base member 201 is sandwiched between the side wall 202b of the cover member 202 and the guide wall 217. The cover member 202 is guided to move laterally with respect to the member 201. In this way, the cover member 202 is arranged at the first position displaced to the right with respect to the base member 201. It should be noted that this first position is a detachable position where the cover member 202 can be detached from the base member 201 on the back side, and the opening of the base member 201 can be opened by disposing the cover member 202 at the detachable position. It is in a state where it can be released (engaged state).

Then, when the cover member 202 is slid from the first position toward the left side, as shown in FIG. 10(B), each engagement piece 220 abuts on the end of each engagement groove 250 and the cover member 202 is covered. The left end portion of the side welded portion 223 abuts on the covering wall 267 and is arranged at a second position where sliding movement is restricted. At this time, the locking pieces 203, 203 of the base member 201 are inserted into the locking holes 222, 222 of the cover member 202 on the right short side. On the short side on the left side, the screw covering piece 602 is locked to the locked piece 602a of the base member 201, the locking piece 603 is locked to the locked piece 603a of the base member 201, and the cover side is provided. The left end of the welded portion 223 is housed in the housing recess 268 of the covering wall 267 and abuts the inner wall of the housing recess 268 (see FIG. 15D).

Further, the protrusion 215 formed on the side wall 201b is fitted into the groove 216 formed on the guide wall 217 so that the cover member 202 cannot move from the second position to the first position unless an external force of a predetermined amount or more is applied. become. Since the right portion of the protruding surface of the protrusion 215 has a larger inclination angle with respect to the side wall 201b than the left portion, when the cover member 202 is moved from the first position to the second position with respect to the base member 201, the guide wall 217 of the guide wall 217 is moved. The right end portion is unlikely to be caught by the protrusion 215, and when the cover member 202 is moved from the second position to the first position with respect to the base member 201, the inner surface of the groove 216 abuts the protrusion 215 to release the fitting state. It becomes difficult to be done.

As described above, by disposing the cover member 202 at the second position, the cover member 202 is assembled to the base member 201, the base member 201 and the cover member 202 are aligned (merged), and the base member 201 is removed. The opening is closed (locked state), and the later-described sealing is possible. It should be noted that this second position is a separation regulation position in which the separation of the cover member 202 from the base member 201 to the rear side is restricted by the engagement pieces 220 being engaged with the engagement grooves 250. .. In addition, each engagement piece 220 and each engagement groove 250 constitute a slide movement support means that supports (guides) the cover member 202 to the base member 201 so as to be slidable between the first position and the second position. To do.

As described above, in order to change the substrate case 200 of this embodiment from the closed state to the opened state, first, the cover member 202 is slid along the base plate 201a of the base member 201 from the second position to the first position side. If not, the locked state of the cover member 202 with respect to the base member 201 cannot be released, and the locking action effectively prevents the cover member 202 from being detached from the base member 201, that is, lifted up.

Further, in the closed state, the mounting hole 234 of the sealing piece 230 is arranged at the position facing the screw hole 210, the mounting hole 227 is arranged at the position facing the screw hole 209, and the mounting hole 610 is formed in the cover side sealing portion 224. The cover-side welded portion 223 is placed at a position opposite to the screw hole 611 (see FIG. 5) formed therein (see FIG. 15D).

Here, for example, when a manufacturer of the pachinko gaming machine 1 stores the main substrate 11 in the substrate case 200 and ships it to a game shop or the like, the cover-side welding portion 223 and the base-side welding that are welding portions are performed. The portion 207 and the portion 207 are brought into a sealed state (also referred to as a first sealed state) by ultrasonic welding (caulking) using, for example, an ultrasonic welding machine. By thus welding the cover-side welded portion 223 and the base-side welded portion 207, the sliding movement of the cover member 202 from the second position to the first position side with respect to the base member 201 is restricted, so that the base member The cover member 202 cannot be opened unless at least a part of the cover member 201 or the cover member 202 is destroyed, that is, when the substrate case 200 is opened, a trace of the trace remains (first sealed state). ..

Further, after the closing screw 226 is inserted into the mounting hole 610 from the front side and screwed into the screw hole 611 of the cover-side sealing portion 224, the sealing seal 400 (so as to straddle the cover-side sealing portion 224 and the base-side sealing portion 229. (See Fig. 3). In this way, by sticking the sealing seal 400 so as to extend over the cover-side sealing portion 224 and the base-side sealing portion 229, when the cover member 202 is slid from the second position to the first position with respect to the base member 201, the sealing is performed. Since the seal 400 is broken, when the substrate case 200 is opened, the trace is left in a sealed state (also referred to as a second sealed state or a sealed state).

Further, a U-shaped seal protection cover 228 (see FIG. 3) made of a translucent synthetic resin material is attached so as to sandwich the cover member 202 and the base member 201 so as to cover the attached seal 400. The one-way screw 219 attached to the sealing piece 228a (see FIG. 3) provided on the lower surface of the seal protection cover 228 is inserted into the insertion hole 218 of the cover member 202, and the screw member 222c is inserted into the locking cylinder 222b. The seal protection cover 228 is attached to the cover member 202 by being screwed into a screw hole (not shown) of (see FIG. 3).

That is, once the one-way screw 219 is attached to the screw hole of the screw member 222c (see FIG. 3), even if a tool such as a screwdriver is inserted into the operation groove, the one-way screw 219 cannot be rotated in the reverse direction. Since it is a mounting member that cannot be removed from the inside, it cannot be removed unless the connecting piece or the like of the sealing piece 228a is cut (destroyed). Therefore, unless the sealing piece 228a is cut and separated from the seal protection cover 228, the seal protection cover 228 cannot be removed to open the cover member 202, that is, when the substrate case 200 is opened, a trace thereof is left. The remaining sealed state (third sealed state) is obtained.

In addition, after the sealing member 640 is fitted into the fitting recess 620d of the sealing piece 620, the one-way screw 623 attached from the rear side to the attachment hole 620c is screwed into the screw hole 642, whereby the sealing member 640 is formed. Is attached to the sealing piece 620.

More specifically, as shown in FIG. 12A, when the sealing member 640 is attached to the sealing piece 620, the protrusion 640b is inserted into the fitting portion formed by the fitting recess 620d and the notch recess 206, A part of the cylindrical portion 640a and the protrusion 640b are fitted into the fitting recess 620d. As a result, the regulation protrusion 641 is inserted into the regulation hole 624. The fitting recess 620d is formed in a non-circular shape in a front view, and the two restricting protrusions 641 are inserted into the restricting hole 624 to center the mounting hole 620c of the sealing member 640 with respect to the sealing piece 620. The turning is restricted (see FIG. 12C).

As shown in FIG. 12B, when the sealing member 640 is held by the sealing piece 620, the one-way screw 623 is inserted into the mounting hole 620c and screwed into the screw hole 642, whereby the sealing member 640 is attached to the sealing piece 620. The sealing member 640 is arranged so as to project toward the base member 201 side when attached to the sealing piece 620.

In this way, by assembling the base member 201 and the cover member 202 and attaching the sealing member 640 to the sealing piece 620 in a state where the cover member 202 is arranged at the second position with respect to the base member 201, As shown in FIG. 13A, when the cover member 202 is slid from the second position to the first position side (left side in FIG. 13) with respect to the base member 201, the inclined surface of the rib 645 of the sealing member 640. The sliding movement of the cover member 202 to the first position side with respect to the base member 201 is regulated by the contact of the left side wall 201d of the base member 201 with the base plate 201.

In other words, when the cover member 202 is held by the sealing piece 620 and the cover member 202 is moved in the opening direction with respect to the base member 201, the sealing member 640 contacts the base member 201 and opens the cover member 202 in the opening direction ( It is arranged at a position that can prevent the sliding movement to the first position side). Further, for example, by screwing the one-way screw 623 attached to the sealing piece 620 into the base member 201, unlike the case where the sliding movement of the cover member 202 to the first position side with respect to the base member 201 is restricted, The stop member 640 is not connected to the base member 201 while being held by the sealing piece 620, and is arranged separately from the base member 201 and in an independent state.

More specifically, the cover member 202 is slidably supported on the base member 201 between a first position and a second position by a slide movement support unit including an engagement piece 220 and an engagement groove 250. Thus, the sealing member 640 abuts the base member 201 and moves the cover member 202 from the second position toward the first position, that is, in the unsealing direction, because it cannot be separated from the base member 201 unless it moves to the first position. If it cannot be moved, the substrate case 200 cannot be opened. In this way, by assembling the base member 201 and the cover member 202 and attaching the sealing member 640 to the sealing piece 620 in a state where the cover member 202 is arranged at the second position with respect to the base member 201, As shown in FIG. 13B, it cannot be opened unless the connecting piece 621 is cut to separate the sealing piece 620 and the sealing member 640 from the cover member 202. The remaining sealed state (fourth sealed state) is obtained.

In this embodiment, the manufacturer puts the substrate case 200 in the first to fourth sealed states at the manufacturing stage and then ships it to a game shop or the like, but it is not always the first to fourth sealed states. Therefore, it may be shipped in at least any one of the first to fourth sealed states, or may be shipped without any sealed state. ..

Further, since the sealing member 640 is attached to the sealing piece 620 by the one-way screw 623, it is difficult to remove the sealing member 640 by removing the one-way screw 623, but it is necessary to pinch and rotate the sealing member 640. Then, it is conceivable to remove the one-way screw 623 from the sealing piece 620. However, the fitting recess 620d and the sealing member 640 are formed in a non-circular shape, the two restricting protrusions 641 are inserted into the restricting holes 624, and the protrusion 640b is formed by the fitting recess 620d and the notch recess 206. Since the rotation of the sealing member 640 with respect to the sealing piece 620 is restricted by being inserted into the fitted portion, the sealing member 640 is rotated with respect to the sealing piece 620 as described above. It is possible to prevent the one-way screw 623 from being removed from the sealing piece 620.

Further, since the rib 645 of the protrusion 640b is formed in a wedge shape by having the inclined surface 645b, when the cover member 202 is moved to the first position side as shown in FIG. The inclined surface 645b comes into contact with the left side wall 201d at an angle. Therefore, when the cover member 202 is slid, the inclined surface 645b is gradually brought into pressure contact with the left side wall 201d, so that the sealing member 640 and the connecting piece 621 are prevented from being damaged by the impact at the time of contact. ..

Further, when the cover member 202 is slid, the inclined surface 645b rides on the notch concave portion 206 of the left side wall 201d, so that the friction of the engaging piece 220 with respect to the engaging groove 250 gradually increases and it is difficult for the sliding movement. Therefore, opening can be made difficult.

In addition, since the above-described recessed groove 630 is formed at a position corresponding to the cutout recess 206 in the left side wall 201d, the cover member 202 should be forcibly slid toward the first position in the fourth sealed state. In this case, the left side wall 201d is easily damaged, so that it is easy to find that the left side wall 201d may have been tampered with.

After the fourth sealing state is set, for example, when it is necessary to release the fourth sealing state for inspection of the main board 11 or the like, as shown in FIG. By cutting with CT or the like, the sealing member 640 together with the sealing piece 620 is separated from the cover member 202, so that the cover member 202 can be moved to the first position side. In this way, the sealing member 640 is held only by the one-way screw 623 on the cover member 202 of the base member 201 and the cover member 202, and is attached by connecting the one-way screw 623 between the base member 201 and the cover member 202. Not a thing.

Therefore, when the connecting piece 621 is cut by the cutter CT or the like, the sealing member 640 together with the sealing piece 620 is separated from the cover member 202, and the sealing member 640 does not remain on the base member 201 side unlike the conventional case. Therefore, when the cover member 202 is returned to the second position after being illegally opened, the cut traces will not be difficult to understand.

In addition, after the first sealed state, for example, when it is necessary to release the first sealed state for inspection of the main substrate 11, the cover-side welded portion 223 needs to be separated from the cover member 202. The base-side welded portion 207 and the cover-side welded portion 223 cannot be welded again to the first sealed state. In addition, when it is necessary to release the second sealed state, it is difficult to peel the sealing seal 400 so as not to break it, and thus the second sealed state cannot be achieved. Further, when it is necessary to release the third sealed state, it is necessary to separate the sealing piece 228a from the seal protection cover 228. Therefore, the sealing piece 228a is connected to the seal protection cover 228 to set the third sealed state. Can not do it. Further, when the fourth sealed state needs to be released, the sealing piece 620 needs to be separated from the cover member 202, so the sealing piece 620 is connected to the cover member 202 to be in the fourth sealed state. I can't.

In this way, when the first to fourth sealed states are released, the sealing piece 230 can be used to bring the sealed state again. In this case, first, in the closed state, the mounting hole 234 of the sealing piece 230 in the cover member 202 matches the screw hole 210. Here, when the one-way screw 240a housed in the sealing piece 230 is screwed into the screw hole 210 with a driver, the cover member 202 is attached to the base member 201 in a non-separable manner.

That is, once the one-way screw 240a is attached to the screw hole 210, even if a tool such as a screwdriver is inserted into the operation groove, the one-way screw 240a cannot be rotated in the reverse direction, that is, the one-way screw 240a cannot be removed from the screw hole 210 again. Therefore, the substrate case 200 cannot be opened without cutting (destroying) a predetermined portion of the substrate case 200 (for example, the connecting piece 233 of the sealing piece 230), that is, the substrate case 200 is opened. In this case, the state becomes a sealing state (fifth sealing state) in which the trace remains.

Further, when the substrate case 200 is opened for inspection of the main substrate 11 or the like, not only the connecting piece 233 of the sealing piece 230 needs to be cut, but also the one-way screw 240 a screwed into the screw hole 210 and the cover member 202. Since the tubular portion of the sealing piece 230 that has been cut off from the base member 201 cannot be removed and remains, it is not possible to attach the one-way screw 240a to the sealing piece 230 and attach it to the base member 201 in the same manner. ..

Next, the case of releasing the first sealed state will be described with reference to FIGS. 14 to 16. As shown in FIG. 14, by sliding the cover member 202 from the first position to the second position with respect to the base member 201, the cover-side welded portion 223 is arranged to face the back side of the base-side welded portion 207. It Further, the insertion piece 264 is inserted into the connection tubular portion 286 through the opening 287.

As shown in FIG. 15(A), when the substrate case 200 is opened after the first sealing state, the cutter CT, a nipper, or a tool such as a saw is used to connect the connecting portions 280a and 280b of the cover member 202. If the cover-side welded portion 223 fixed to the base-side welded portion 207 is separated from the main body of the cover member 202 by cutting the tubular portion 286, the cover is left in the state where the cover-side welded portion 223 remains in the base-side welded portion 207. The member 202 can be slid to the first position side and opened.

In the first sealed state, the connecting portions 280a and 280b are covered by the covering wall 267 when the cover member 202 is arranged at the second position, so that when the connecting portions 280a and 280b are cut by the cutter CT, the covering walls 280a and 280b are covered. Since it is difficult to insert the cutter CT into the accommodation recess 268 inside 267, it is highly likely that the cutter CT will be cut together with the covering wall 267. Therefore, when the connecting portions 280a and 280b are cut and opened, there is a high possibility that a trace of cutting will remain on the covering wall 267, so that it is easy to discover that there is a possibility that they have been opened.

Further, when the connecting cylinder portion 286 is cut by using the gap S1, as shown in FIG. 14B, the connecting cylinder portion 286 is moved from the rear side to the connecting cylinder portion 286 with respect to the sliding movement direction of the cover member 202. It is conceivable to dispose the cutters CT in a direction substantially orthogonal to each other and make a cut while reciprocating the cutters CT up and down toward the front side. In this case, since the periphery of the insertion piece 264 is covered with the connecting tube portion 286, cutting the cutter CT toward the front side facilitates cutting of the insertion piece 264 together with the connecting tube portion 286.

However, in the case of illegal opening, if the insertion piece 264 is cut and disappears together with the connecting tube portion 286, the mark of illegal opening is conspicuous, so that the connecting tube portion 286 is not cut or damaged. It is possible to try to disconnect.

As shown in FIG. 16, the outer surfaces 286a to 286c that are the facing surfaces of the connecting tubular portion 286 that face the insertion piece 264, and the outer surfaces 264a to 264c that are the facing surfaces of the inserting piece 264 that face the connecting tubular portion 286, It is a non-flat surface having a convex portion and a concave portion in part. Specifically, the outer surfaces 264a to 264c that are the facing surfaces of the insertion piece 264 that is the connecting portion are connected by a virtual straight line (for example, a virtual straight line L1) that connects any two points (for example, P1 and P2) on the facing surface. It has a convex portion (for example, a corner portion of the insertion piece 264) protruding toward the tubular portion 286.

Therefore, in order to cut the connecting tubular portion 286 without damaging the insertion piece 264, it is necessary to cut the blade of the cutter CT from the three sides along each outer surface 286a to 286c as shown in FIG. Not only is it extremely difficult to insert the cutter CT from the front side to hit the connecting cylinder part 286 on the front side in the space surrounded by the support plates 270a and 270b, but also to face the connecting cylinder part 286 and the insertion piece 264. This is more difficult than when the surface is flat. Further, since the outer surfaces 264a to 264c and 286a to 286c are arranged in close proximity to each other, if the blade of the cutter CT is slightly protruded from the outer surfaces 286a to 286c, the outer surfaces 264a to 264c are damaged, and thus traces of cutting remain. It will be easier.

The cut mark formed on the insertion piece 264 can be visually recognized through the connecting tubular portion 286 because the connecting tubular portion 286 is formed of a transparent member. Further, the insertion piece 264 and the insertion hole 321 do not have to be rectangular in cross section and may be substantially circular in cross section, and can be variously modified.

Further, the facing surface between the connecting portion and the corresponding connecting portion may be formed as a curved surface instead of a flat surface. That is, the facing surface is not limited to one formed by a plurality of flat surfaces (for example, the outer surfaces 264a to 264c, 286a to 286c) or a curved surface as described above, but may be one flat surface. Good. For example, the facing surface may be formed in a substantially arc shape in side view, may be formed in an uneven shape, or may be formed in a mountain valley shape. Further, in the above description, one facing surface of the connecting portion and the connecting corresponding portion is provided so as to cover all of the other facing surface, but, for example, one of the outer surfaces 286a to 286c of the connecting tubular portion 286 is provided. May be provided so as to cover at least a part thereof, such as being opened.

As described above, the board case 200 of the pachinko gaming machine 1 as the embodiment of the present invention has the base member 201 as the first member and the cover member 202 as the second member, and is the main body as the circuit board. The board case 200 for housing the board 11, the fitting recess 620d of the sealing piece 620 as the sealing member holding portion provided on the base member 201, and the sealing piece after the base member 201 and the cover member 202 are assembled And a sealing member 640 that holds the board case 200 in the fourth sealed state by being held in the fitting recess 620d of the sealing piece 620. The sealing member 640 is held in the fitting recess 620d of the sealing piece 620. In the opened state, when the cover member 202 is moved to the first position side which is the unsealing direction with respect to the base member 201, the cover member 202 is brought into contact with the base member 201 so as to prevent the cover member 202 from moving toward the first position side. Will be placed.

By doing so, when the connecting piece 621 is cut to open the substrate case 200, the sealing member 640 is completely separated from the cover member 202, and the base member 201 and the cover member 202 are reassembled. However, since the fitting recess 620d of the sealing piece 620 does not return to the state before cutting (the state before cutting cannot be reproduced), it is easy to find that the substrate case 200 is illegally opened.

In addition, the substrate case 200 supports the cover member 202 so as to be slidable toward the first position side over a predetermined section (for example, a section from the first position to the second position) from the second position which is the sealing position. The sealing member 640 includes the engaging piece 220 as the slide movement supporting means and the engaging groove 250, and the sealing member 640 contacts the base member in the section from the first position to the second position to the first position side of the cover member 202. Prevent the movement of. In this way, the structure can be simplified because the sealing member 640 may contact the base member 201 in the section where the cover member 202 is restricted to slide to the first position side by the slide movement supporting means.

Further, the sealing member 640 is held by being attached to the fitting recess 620d of the sealing piece 620 by a one-way screw 623 which is a screw member, and the sealing member 640 rotates in the rotation direction of the one-way screw 623 with respect to the fitting recess 620d. Rotation restriction means for restricting rotation to (for example, a non-circular fitting recess 620d and a sealing member 640, two restriction projections 641 and a restriction hole 624, a fitting recess 620d and a cutout recess 206. By providing the fitting portion and the protrusion 640b), it is possible to prevent the one-way screw 623 from being removed from the fitting recess 620d by rotating the sealing member 640.

In addition, the protrusion 640b of the sealing member 640 has a wedge-shaped portion (for example, a portion of the rib 645 where the inclined surface 645b is formed), and the wedge-shaped portion is used when the cover member 202 is moved to the first position side. Since the sealing member 640 is gradually brought into contact with the base member 201 by abutting against the base member 201 and preventing the movement toward the first position side, the fitting of the cover member 202 due to the impact of the abutment. It is possible to prevent damage to the fitting recess 620d and the sealing member 640.

Further, the sealing member 640 has the protruding portion 640b that fits into the cutout recess 206 of the base member 201 while being held in the fitting recess 620d, so that the sealing member 640 is rotated to remove the one-way screw 623. This can be prevented, and damage to the fitting recess 620d of the cover member 202 and the sealing member 640 due to the impact of contact can be prevented.

In addition, the substrate case 200 serves as a second fixing portion that is connected to the base-side welding portion 207 as a first fixing portion provided on the base member 201 and the cover member 202 via a connecting cylinder portion 286 as a connecting portion. The cover-side welded part 223 and the base-side welded part 207 and the cover-side welded part 223 are fixed to each other (for example, ultrasonic welding), whereby the first sealed state can be obtained. The member 201 has an insertion piece 264 as a connection corresponding portion that comes into contact with or comes close to the connection tubular portion 286 when the cover member 202 is located at the second position which is the sealing position. The facing surface facing the H.264 has a shape corresponding to each other (see FIG. 16), and the outer surface 264a to 264c, which is the facing surface of one of the connecting tubular portion 286 and the insertion piece 264, is an arbitrary surface on the facing surface. It has a corner portion of the insertion piece 264 as a convex portion projecting to the other side from a virtual straight line (for example, virtual straight line L1) connecting points (for example, P1 and P2).

With this configuration, when the cover-side welded portion 223 is separated from the cover member 202 and the connecting cylinder portion 286 is cut to release the sealed state, one of the connecting cylinder portion 286 and the insertion piece 264 is cut. The outer surfaces 264a to 264c, which are the facing surfaces, are insertion pieces 264 as convex portions that project to the other side from a virtual straight line (for example, a virtual straight line L1) that connects arbitrary two points (for example, P1 and P2) on the facing surface. By having the corner portions, it becomes difficult to cut along the facing surface, and the insertion piece 264 that comes close to or comes into contact with the connecting tubular portion 286 is easily cut together. Therefore, the trace of cutting is likely to remain not only in the connecting tubular portion 286 but also in the insertion piece 264, and thus it is easy to find that the sealed state may have been unlawfully released.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configurations are not limited to these embodiments, and modifications and additions within the scope not departing from the gist of the present invention are included in the present invention. Be done.

For example, in the above-described embodiment, the cover member 202 is provided so as to be slidable between the first position and the second position with respect to the base member 201, and the sealing member 640 is provided on the cover member 202 that is moved when opening. It was designed to be held by the provided sealing piece 620, but the present invention is not limited to this, and, for example, as in the substrate case 200A as the modified example 1 shown in FIG. The member 640 may be held by a sealing piece 620 provided on the base member 201. In this case, the cover member 202 is slid with respect to the base member 201 when the cover member 202 is slid to the first position side. It suffices that the cover member 202 is arranged at a position where it comes into contact with the cover member 202 to prevent the cover member 202 from moving to the first position side, that is, on the track when the cover member 202 is moved to the first position side.

That is, in the substrate case 200 that is opened by moving one of the base member 201 and the cover member 202 with respect to the other, the sealing member 640 is a sealing piece provided on the cover member 202 that is moved when opening. It may be held not only by the one held by 620 but also by the sealing piece 620 provided on the base member 201 which is not moved when opening.

Further, in the above-described embodiment, the base member 201 and the cover member 202 are slidably supported in the section between the first position and the second position, but the present invention is not limited to this. Instead, for example, as in the substrate case 200B of the second modified example shown in FIG. 18A, the cover member 202 with respect to the base member 201 is shown in a predetermined section from the sealing position (for example, shown by a solid line in FIG. 18A). A rotation shaft 650 provided on the cover member 202 and a bearing provided on the base member 201 as rotation support means for rotatably supporting in the unsealing direction over a rotation section from a position to a position indicated by a chain double-dashed line). In the one including the portion 651, the sealing member 640 may contact the base member 201 in the predetermined section to prevent the cover member 202 from moving in the unsealing direction. By doing so, the sealing member 640 abuts on the base member 201 and rotates when the movement of the cover member 202 in the unsealing direction with respect to the base member 201 is restricted by the rotation supporting means. Since the movement may be restricted, the structure can be simplified.

Further, in the substrate case 200B shown in FIG. 18(A), the sealing member 640 was provided on the sealing piece 620 provided on the cover member 202 side, but the substrate of Modification 3 shown in FIG. 18(B). Like the case 200C, the opening direction of the cover member 202 with respect to the base member 201 from a sealing position over a predetermined section (for example, a rotation section from a position shown by a solid line to a position shown by a chain double-dashed line in FIG. 18A). In the one provided with the rotation shaft 650 provided on the base member 201 and the bearing portion 651 provided on the cover member 202 as the rotation support means for rotatably supporting the base member 201, the sealing member 640 is the base member. It may be provided on the sealing piece 620 provided on the cover member 202 that is rotated with respect to 201.

In addition, in the embodiment and the modified examples 1 to 3, the cover member 202 covers a predetermined section from the base member 201 by the slide movement support means or the rotation support means in the predetermined section from the sealing position (second position). It was designed to be movably supported in one unsealing direction, but the present invention is not limited to this, and the predetermined section is at the sealing position as in the embodiment and the modified examples 1 to 3. May be supported in a part of the section from the opening position to the opening position, or may be supported in the entire section from the sealing position to the opening position.

Further, when the substrate case 200 is opened, the cover member 202 may be opened by moving the cover member 202 in any direction with respect to the base member 201 material. Even in such a case, even if the cover member 202 is moved in an arbitrary opening direction, the sealing member comes into contact with the base member 201 to prevent the cover member 202 from moving in the opening direction. It should be arranged.

Further, in the above-described embodiment, when the cover member 202 is slidably moved from the second position to the first position with respect to the base member 201, the sealing member 640 comes into contact with the base member 201 to restrict the movement. Was there. That is, the cover member 202 is in a state in which it cannot be moved to the first position side at the second position by the sealing member 640, but the present invention is not limited to this, and for example, the base member can be moved by sliding. If the cover member 202 can be detached from the base member 201 or if most of the main board 11 is opened so that it is not easy to perform an illegal act, the cover member 202 is moved to the first position side with respect to the base member 201. The movement may be regulated by the sealing member 640 when a predetermined amount of movement is made (for example, when the movement is made between the second position and the first position).

Further, in the above-described embodiment, the fitting recess 620d of the sealing piece 620 connected to the main body of the cover member 202 via the connecting piece 621 is described as an example of the sealing member holding portion. Is not limited to this, and the sealing member holding portion may be provided on the main body of the cover member 202 without a connecting piece or the like. Further, although the sealing piece 620 is provided outside the cover member 202, it may be provided inside the cover member 202.

Further, in the above-described embodiment, the sealing member 640 cannot be removed unless the connecting piece 621 or the like of the sealing piece 620 is cut (destroyed) by the one-way screw 623. In other words, a trace remains when it is removed. The substrate case 200 can be brought into a sealed state by being attached to the sealing piece 620 at, but the present invention is not limited to this, and the sealing member 640 is the base member. If the substrate case 200 can be brought into a sealed state by holding the sealing member 620 after assembling the 201 and the cover member 202, for example, the sealing member 620 can be ultrasonically treated. It may be fixed by welding or the like, may be attached to the sealing piece 620 by an attachment means other than a one-way screw, and once it is locked, the locking state cannot be released unless the predetermined portion is destroyed. May be locked to the sealing piece 620. Further, instead of the sealing member 640, for example, it may be a part of the one-way screw 623 protruding from the sealing piece 620.

Further, in the above-described embodiment, the main board 11 on which the game control microcomputer 100 for controlling the game is mounted is described as an example of the circuit board, but a performance control microcomputer for controlling the performance is mounted. It may be another circuit board such as the produced effect control board 12 or the like.

Further, in the substrate case 200 or the sealing sticker 400 in the above-described embodiment, a serial number, which is identification information for identifying each main board 11 or the sealing sticker 400, may be displayed (printed). By doing so, it is possible to easily recognize which main substrate 11 or sealing sticker 400 is installed. Further, as the identification information for identifying each of the main board 11 and the seal 400, a two-dimensional code that can be read by a predetermined reading device is displayed (printed) by encoding the information for identification. You may do it.

FIG. 19A is a diagram showing a serial number and a two-dimensional code displayed (printed) as identification information on the identification information table portion of the seal 400. In FIG. 19A, the serial number and the two-dimensional code can be read visually.

In this way, if the identification information (serial number or two-dimensional code) is displayed (printed) so as to be visually readable, copying may be facilitated and may be misused. Therefore, in order to make the display of the identification information (serial number or two-dimensional code) difficult or invisible, the film member 2000 is attached onto the display of the identification information as shown in FIG. 19B. Good.

The film member 2000 can be seen through a visible portion through a specific visualization member 3000 as shown in FIG. Any number or two-dimensional code can be visually recognized.

The film member 2000 shown in FIG. 19B includes, for example, an optically transparent adhesive layer, a circular polarization filter layer provided on the adhesive layer, and a cholesteric liquid crystal layer provided on the circular polarization filter layer. Any member having a plurality of layers may be used.

The circular polarization filter layer has a left circle on the observation surface side (the opposite side of the adhesive layer on the film member) when natural light is incident from the adhesive layer side (the identification information side when the film member is attached to the seal). It is adjusted to selectively transmit polarized light.

The cholesteric liquid crystal layer is embossed for hologram display. Here, the rotation direction of circularly polarized light that is selectively reflected by the cholesteric liquid crystal layer and the rotation direction of circularly polarized light that transmits through the circular polarization filter layer from the adhesive layer side to the observation surface side are set to be opposite directions. There is. That is, the cholesteric liquid crystal layer selectively reflects right-handed circularly polarized light, and the left-handed circularly polarized light is selectively transmitted from the adhesive layer side to the observation surface side of the circularly polarized light filter layer.

The visualization member 3000 shown in FIG. 20A may be composed of, for example, a left circular polarization filter.

When the identification information display section to which the film member 2000 is attached is viewed, the hologram display is viewed as shown in FIG. In this case, the hologram display becomes an obstacle, and the serial number or the two-dimensional code that is the identification information cannot be visually recognized. The serial number and the two-dimensional code need only be at least difficult to be visually recognized by the hologram display, and may not be completely invisible. The two-dimensional code may be almost visually recognizable if it cannot be read by the reading device.

Here, as shown in FIG. 20B, when the identification information display section to which the film member 2000 is attached is visually observed through the visualization member 3000 including the left circular polarization filter, the reflected light from the cholesteric liquid crystal layer is visually recognized. Can not. On the other hand, the left circularly polarized light included in the reflected light from the serial number or the two-dimensional code, which is the identification information, passes through the circularly polarized light filter layer, the cholesteric liquid crystal layer, and the left circularly polarized light filter. That is, the hologram display is not visually recognized through the visualization member 3000 including the left circular polarization filter, and the serial number or the two-dimensional code, which is the identification information, is clearly visible. The two-dimensional code can be read by the reading device through the visualization member including the left circular polarization filter.

As described above, the film member 2000 is pasted on the display of the identification information display unit, which makes it difficult or impossible to visually display the serial number, the two-dimensional code, or the like when viewed without the specific visualization member 3000. As a result, it is possible to prevent the identification information from being read by a third party with a simple configuration. Further, since the display can be visually confirmed only by visually observing it through the visualization member 3000, it is possible to prevent the display confirmation work by the administrator from being troublesome.

Although the example in which the film member 2000 is attached to the seal 400 is shown, the film member 2000 may be attached to any place of the slot machine or the pachinko gaming machine. For example, instead of being directly attached to the seal sticker, the seal sticker may be attached to the substrate case so that the display of the seal sticker becomes difficult or impossible to visually recognize. If the identification information such as the manufacturing number is displayed on the game board, the film member 2000 may be attached to the gaming board to make the identification information such as the manufacturing number difficult or impossible to visually recognize. Good.

The identification information display part to which the film member 2000 is attached is preferably a flat part on which the visualization member 3000 can be adhered. Since the visualization member 3000 can be in close contact, the identification information can be confirmed smoothly.

It is desirable to provide a space around the identification information display unit to which the film member 2000 is attached so that the visualization member can be brought close to it. By providing such a space, it is possible to smoothly confirm the identification information.

Although the film member 2000 has been described as having an adhesive layer and attached, the film member 2000 may be placed on the identification information display unit without having an adhesive layer. In this case, it is preferable to provide a holding member for holding the film member 2000 around the identification information display portion or the identification information display portion.

In FIG. 19B, an example in which one film member 2000 is pasted on the display of the identification information display section is shown, but a plurality of film members 2000 such as pasting the film member 2000 for each identification information display section are shown. May be attached. At this time, as each film member 2000, a film member 2000 that can be visually recognized by different visualization members 3000 may be used. As a result, security can be improved.

A holding member for holding the visualization member 3000 may be provided near the identification information display unit to which the film member 2000 is attached. Accordingly, an administrator who wants to confirm the information displayed on the identification information display unit can confirm the information while the visualization member 3000 is held by the holding member, and thus the confirmation work is facilitated. In particular, when reading a two-dimensional code, since the work is carried out while carrying the reading device, the work efficiency can be improved by holding the visualization member 3000 by the holding member.

Further, in the above-described embodiment, the pachinko gaming machine 1 is illustrated as an example of the gaming machine, but the present invention is not limited to this, and for example, a predetermined number of gaming balls are inside the gaming machine. The number of balls used for the game is subtracted, while the number of balls used for the game is added, while the number of balls used for the game is added, and the number of balls used for the game is added. The present invention can also be applied to a so-called enclosed game machine that is stored as.

Further, in the above embodiment, the pachinko gaming machine is applied as an example of the gaming machine, but for example, the game can be started by setting a predetermined number of bets for one game using the gaming value. At the same time, one game is completed by deriving the display result on a variable display device capable of variably displaying a plurality of types of symbols that can be identified, and a prize is awarded according to the display result derived on the variable display device. It can also be applied to slot machines that can be generated.

Further, in the above embodiment, a spherical game ball (pachinko ball) was applied as an example of the game medium, but the present invention is not limited to a spherical game medium, and for example, a non-spherical game medium such as a medal. May be
