Description

  The present invention relates to a gaming machine having a computer circuit, and more particularly to a gaming machine that enables powerful lamp effects.

  A ball and ball game machine such as a pachinko machine has a symbol start port provided on the game board, a symbol display unit for displaying a series of symbol variation modes such as stopping a plurality of display symbols after varying a predetermined time, and an opening / closing plate It is configured with a grand prize opening that opens and closes. When the detection switch provided at the symbol start port detects the passing of the game ball, the game ball is in a winning state and the symbol display unit changes the display symbol for a predetermined time. After that, when the symbol stops in a predetermined manner such as 7-7-7, a big hit state is established, and the big winning opening is repeatedly opened to generate a profit state advantageous to the player.

  The symbol display unit is usually composed of a liquid crystal display, and executes various symbol effect operations including a reach effect, a notice effect, and a jackpot effect. Reach production is a design production that continues to be a big hit state in one step and excites the player, and the notice production is a sudden appearance of some character in the middle of the movement of the design, It is a design effect that warns of a big hit. The jackpot effect is an effect executed in a big hit state, and a more flashy symbol effect is executed in response to the joy of the player.

  At the time of execution of such a symbol effect, a lamp effect is also executed in synchronism with this, and at the time of a reach effect or a big hit effect, a lamp is flashed in response to the symbol effect on the liquid crystal display. Also, after entering the big hit state, a more flashy lamp effect is executed. In addition, since the lamp that realizes the lamp effect can only be arranged at the peripheral part of the gaming machine, normally, lighting data that binaryly defines the lighting state of the lamp is transmitted as a serial signal to the peripheral part of the gaming machine. ing.

  As mentioned above, lamp production is indispensable to realize powerful performance operation, but if the number of lamps is increased in the dark to increase the power of lamp production, the lighting control becomes complicated, In order to enhance the production effect without increasing the number of lamps, for example, a side lighting unit using a chrome-plated reflector is also proposed.

JP 2009-125493 A

  However, since chromium plating has conductivity, there is a problem that the lamp and its driving element are destroyed by electrostatic discharge from the reflector simply by disposing a conductive reflector. In such a case, since there are many game halls in which the destroyed lamps and driving elements are left as they are, the intended lamp effect cannot be realized permanently.

  In addition, even if the lamp and driving element are not destroyed, when transmitting lighting data as a serial signal, there is a problem of superimposition of discharge noise, etc. Nonetheless, the unnatural lamp production continues.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a gaming machine that can realize a powerful lamp effect and reduce the possibility of discharge noise and discharge breakdown.

In any case, the light emitter is driven by a driver element controlled by a computer circuit, and the driver element acquires an n-bit length shift register and output data of each shift register in synchronization with an acquisition command. Typically, an n-bit latch circuit and an output circuit that outputs n-bit data of the latch circuit in synchronization with an output command are configured.

  Further, it is preferable that the light emitter is disposed on the front surface side of the circuit board while the other circuit elements are disposed on the back surface side of the circuit board.

  FIG. 3 is a perspective view showing components of the electrical decoration display unit 4, and FIG. In addition, although the electrical display part 4 is arrange | positioned at the both right and left sides of the glass door 6, only the electrical display part 4 arrange | positioned at the left side of the glass frame base 50 is shown in figure by FIG.

  As shown in FIG. 4A, the illumination display unit 4 includes a circuit board 51 on which the light emitter LUM and the driver element are mounted, a reflection member 52 disposed so as to cover the circuit board 51, and a reflection member 52. Are formed of an inner lens body 53 having a sawtooth shape and an outer lens body 54 disposed outside the inner lens body 53. The outer surface of the circuit board 51 and the flat surface of the reflecting member 52 are substantially parallel to each other and are set to a separation distance D.

  As shown in FIG. 4B, the outer lens body 54 is formed of a transparent plastic plate that is gently curved outward. Then, the end portion of the outer lens body 54 is fixed to the glass frame base 50, so that the circuit board 51, the reflecting member 52, and the inner lens body 53 are formed in the internal space formed between the glass frame base 50. Are housed together.

  The inner lens body 53 is made of a transparent plastic plate, and has an inner surface 53a that is in contact with the reflecting member 52, and an outer surface 53b that bulges in an arc shape. Here, the inner surface 53a of the inner lens body 53 has a cut groove TH formed in the width direction continuous in the length direction of the inner lens body 53, so that the sectional view of the inner lens body 53 has a sawtooth shape. It has become. In addition, a substantially V-shaped groove GV extends straight in the length direction of the inner lens body 53 at approximately the center of the outer surface 53 b of the inner lens body 53. Note that the substantially V-shaped groove GV is continuously extended in the length direction of the inner lens body 53 although it is interrupted at a position of a concave portion HO described later.

  As shown in FIGS. 3 and 4A, the outer surface 53b of the inner lens body 53 has six sets (total of twelve) of recesses HO, and the inner lens corresponding to the total of twelve recesses HO. Six sets (12 in total) of protrusions PR are formed at corresponding positions on the inner surface 53a of the body (see FIG. 4D). Further, four thin plate-like mounting pieces AT are extended on both sides of the inner lens body 53 in the width direction (see FIG. 3).

  As shown in FIG. 4A and FIG. 4D, the concave portion HO of the inner lens body 53 is formed in a substantially V shape in cross section, and the protrusion PR has an inclined wall 55, a flat surface 56, and a vertical surface. And a wall 57. The vertical walls 57, 57 of the pair (two) of the protrusions PR, PR face each other, thereby forming a substantially U-shaped accommodation space SP in a sectional view. A cut groove TH is also formed in the bottom surface of the accommodation space SP.

  The reflection member 52 has conductivity and gloss (specular reflection) by chrome plating the entire surface of the plastic material. In the length direction of the reflecting member 52, six light guide portions OPN are formed corresponding to the six sets of protrusions PR formed on the inner lens body 53. The light guide part OPN includes a protruding part BX that projects slightly tapered toward the circuit board 51 and an inclined part TR accommodated in the protruding part BX. The inclined portion TR has a triangular peak 61 and is formed in a triangular mountain shape.

  As shown in FIG. 4A, the protrusion BX is formed by four pieces of inclined surfaces 60... 60, and the center of the tip is opened in a rectangular shape. The top surface (opening surface) of each of the inclined surfaces 60... 60 is set to a distance d that is substantially equal to the thickness of the light emitter LUM. Further, an inclined portion TR is provided in the center of the opening of the protruding portion BX so that the triangular peak 61 is located. Then, the inner lens body 53 is assembled so that the inclined portion TR of the reflecting member 52 is accommodated in the accommodating space SP. As illustrated, the triangular peak 61 is positioned backward from the tip opening formed by the inclined surface 60, thereby ensuring an insulation distance from the circuit board 51. In the embodiment, the triangular peak 61 and the light emitter LUM are set to be approximately separated from each other by a distance D-d.

  In the assembled state, the attachment piece AT (FIG. 3) of the inner lens body 53 is accommodated in a receiving groove (not shown) of the reflecting member 52, and the inner lens body 53 is held. In this assembled state, the inner surface of the inclined surface 60 of the reflecting member 52 is brought into contact with the inclined wall 55 of the inner lens body 53, and the bottom surface of the inclined portion TR is in the cut groove TH of the inner lens body 53. It abuts (see FIG. 4A).

  On the surface side of the circuit board 51, six light emitters LUM are arranged corresponding to the openings of the light guide part OPN of the reflecting member 52. Although not particularly limited, here, a single circuit element incorporating light emitting diodes of three primary colors (RGB) is disposed on the circuit board 51 so as to face the light guide unit OPN. The luminous body LUM (see FIG. 4E) has directivity with a relative luminous intensity of 40% or less at a position shifted by ± 60 ° with respect to a vertical line standing upright from the circuit element center O. Yes. The relative luminous intensity at the position shifted by ± 90 ° is 0%.

  Note that all circuit elements other than the light emitter LUM (specifically, the driver element Dr and the current limiting resistor r1) are arranged on the back side of the circuit board 51. The light emitter LUM and other circuit elements are connected via a through hole formed in the circuit board 51 (see FIG. 8B). Here, the through hole is a conduction hole of the circuit board 51, and of course, its inner wall has conductivity in order to connect circuit elements on the front and back surfaces of the circuit board 51.

  As shown in FIG. 4A, an imaginary line connecting the opening center of the protrusion BX and the element center O of the light emitter LUM is arranged to be orthogonal to the circuit board 51, and the top surface of the protrusion BX is a light emitter. It is close to a position almost in contact with the top surface of the LUM. Further, the triangular peak 61 of the inclined portion TR is positioned on the vertical line from the center point O (FIG. 4E) of the light emitter LUM. Therefore, all of the radiated light from the light emitter LUM enters the protruding portion BX, is regularly reflected by the inclined surface of the inclined portion TR, and enters the inner lens body 53.

  The radiated light that has entered the inner lens body 53 reaches the outer lens body 54 while the refracted light that has passed through the outer surface 53b reaches the outer lens body 54, while the reflected light reflected by the outer surface 53b is reflected by the cut groove TH of the inner surface 53a. Then, it reaches the outer surface 53b again.

  As described above, the radiated light emitted from the light emitter LUM travels while being reflected by the outer surface 53b and the inner surface 53a of the inner lens body 53, but the traveling direction changes in the cut groove TH of the inner surface 53a and becomes critical. Only light directed toward the outer surface 53b of the inner lens body 53 at an angle less than the angle (the maximum incident angle at which refraction occurs) is emitted from the inner lens body 53 toward the outer lens body 54.

In other words, light directed toward the outer surface 53b of the inner lens body 53 at an angle equal to or greater than the critical angle is not emitted from the inner lens body 53, but becomes an internal traveling wave that travels inside again. By the way, according to Snell's law, when the incident angle from the medium A to the medium B is θa, when the absolute refractive index of the medium A is na and the absolute refractive index of the medium B is nb, SIN (θa) / SIN The relationship (θb) = nb / na is established (see FIG. 4F). Therefore, the critical angle θa is changed from SIN (θa) = nb / na × SIN (90 °) = nb / na to θa = SIN ⁻¹ (nb / na).

  When this Snell's law is applied to this embodiment, since the medium B is air, the refractive index of air is set to nb≈1, and the refractive index of the medium A (plastic material) is set to na = 1.3 to 1.7. Then, the critical angle θa becomes 50 to 36 °. Therefore, in this embodiment, by using a plastic chip material having a refractive index of about 1.5 to 1.6 as the inner lens body 53, a critical angle θa of about 40 ° is realized, and the inner side is formed at an angle greater than the critical angle. The number of reflections is increased by preventing emission of light toward the outer surface 53b of the lens body 53.

  In addition, in this embodiment, since the substantially V-shaped groove GV is formed on the outer surface 53b of the inner lens body 53, the internal traveling wave can be increased also by total reflection at the substantially V-shaped groove GV. . As a result of the above configuration, in this embodiment, although the six light emitters LUM are discretely arranged, the entire illumination display unit 4 can emit light almost uniformly and brightly.

  By the way, the absolute maximum ratings of the light-emitting diodes built in the light-emitting body LUM surface-mounted on the circuit board 51 are about 100 mA pulse forward current and about 5 V reverse voltage, respectively. Accordingly, the current exceeding the absolute maximum rating may cause the light emitting diode to be destroyed by the voltage. The point to be particularly considered in preventing such element destruction is electrostatic discharge to the circuit board 51 due to static electricity charged on the conductive reflecting member 52. In this sense, the circuit board 51, the reflecting member 52, It is necessary to ensure a sufficient separation distance.

  However, in order to allow all the radiated light from the light emitter LUM to enter the inside of the protruding portion BX, the positional relationship between the circuit board 51 and the light guide portion OPN must be separated from the state of FIG. Can not. That is, the top surface of the light guide unit OPN needs to be close to the position of the top surface of the light emitter LUM.

  Therefore, based on the above conditions, the present inventor conducted various experiments on the path of electrostatic discharge from the reflecting member 52 toward the circuit board 51. As a result, (1) the protruding portion corresponding to the planar shape of the light emitter LUM If the opening of the BX is widened to a certain extent, electrostatic discharge from the protrusion BX to the light emitter LUM (particularly the connection terminal T) can be prevented. (2) In addition, electrostatic discharge can be performed in a state where the condition (1) is satisfied. It became clear that it is a through hole provided in the circuit board 51 that tends to be a passage.

  Therefore, in this embodiment, the opening sides A and B of the protrusion BX are set to be not less than twice the maximum lengths a and b including the connection terminal T of the light emitting body LUM, and the opening area A of the protrusion BX. XB is set to be not less than 6 times the maximum area axb of the light emitter LUM, and a through hole is not provided in the prohibited area INH of the circuit board 51 set corresponding to the opening of the protrusion BX. ing. Although different from the illustrated example of FIG. 4E, the light emitting body LUM in which the connection terminal T is not exposed in the width direction, that is, the surface mount type light emitting body LUM in which the connection terminal T is provided on the back side of the plate-like component. It is also preferred to use

  In any case, the prohibition area INH is not particularly limited as long as it is wider than the maximum lengths A and B of each side of the protrusion BX, but preferably at least about the base (each side A ′, B ′) of the protrusion BX. Is set to the size of By adopting such a configuration, the path of electrostatic discharge can be virtually eliminated, and destruction of the light emitter LUM and the driver element can be prevented.

All or part of the effect control unit 22, the liquid crystal control unit 23, and the payout control unit 24 is a sub-control unit.

  By the way, this pachinko machine GM is roughly divided into a frame side member GM1 surrounded by a broken line in FIG. 5 and a board side member GM2 fixed to the back of the game board 5. The frame side member GM1 includes a front frame 3 on which a glass door 6 and a front plate 7 are pivotally attached, and a wooden outer frame 1 on the outside thereof. Is fixedly installed. On the other hand, the board side member GM2 is replaced in response to the model change, and a new board side member GM2 is attached to the frame side member GM1 instead of the original board side member. All except the frame side member GM1 is the panel side member GM2.

And the frame side member GM1 and the board | substrate side member GM2 are electrically connected by the connection connectors CN1-CN4 concentratedly arranged in one place.

  As shown in FIG. 5, the power supply board 20 is connected to the main board relay board 28 through the connection connector CN2, and is connected to the power supply relay board 30 through the connection connector CN3. The main board relay board 28 outputs the system reset signal SYS, the RAM clear signal, the voltage drop signal, the backup power supply, DC12V, and DC32V received from the power board 20 to the main controller 21 as they are. Similarly, the power supply relay board 30 also outputs the system reset signal SYS received from the power supply board 20 and the AC and DC power supply voltages to the effect interface board 27 as they are.

This pachinko machine is designed to retain the stored contents of the RAM of each one-chip microcomputer for at least several days.

  On the other hand, the effect control unit 22 and the liquid crystal control unit 23 are not provided with the power supply backup function described above. However, the system reset signal SYS is commonly supplied to the effect control unit 22 and the liquid crystal control unit 23, and the power reset operation is realized at a timing substantially synchronized with the other control units 21 and 24.

  As shown in FIGS. 5 and 6, the effect interface board 27 includes a command relay board 26, a power supply relay board 30, a frame relay board 31, an effect control board 22, a lamp connection board 34, and a liquid crystal control board 23. Are connected to the inverter board 33.

  As shown in FIG. 6, the effect control unit 22 includes a one-chip microcomputer 40 that executes processing such as sound effects, lamp effects, and data transfer, an EPROM 41 that stores a control program for the one-chip microcomputer 40, and the one-chip microcomputer. 40, an audio reproduction LSI 42 that generates an audio signal based on an instruction from 40, an audio memory (phrase ROM) 43 that stores compressed audio data that is the original data of the generated audio signal, and a watchdog timer WDT. Configured.

  The one-chip microcomputer 40 includes a serial communication circuit SIO and a parallel port PIO. In this embodiment, serial data DATA and shift clock CLOCK are output from serial communication circuit SIO, and latch signal LATCH and operation control signal ENABLE are output from parallel port PIO. Further, a control command CMD ′ and a strobe signal STB ′ are also output from the parallel port PIO.

  The watchdog timer WDT is reset by a clear pulse periodically supplied from the one-chip microcomputer 40. When the clear pulse is interrupted due to a program runaway or the like, a reset signal RESET is output. As a result, the one-chip microcomputer 40 is forcibly reset to the initial state, and the program runaway state is solved.

  As shown in FIG. 6, the control command CMD and the strobe signal (interrupt signal) STB output from the main control board 21 are sent to the one-chip microcomputer 40 of the effect control board 22 via the buffer 48 of the effect interface board 27. Have been supplied. Then, the effect control unit 22 acquires the control command CMD by the reception interrupt process activated by the strobe signal STB. In addition to (a) error notification and other notification control commands, the control command CMD acquired by the effect control unit 22 includes (b) control for specifying an outline of various effect operations resulting from winning at the symbol start opening. Commands (variation pattern commands) are included. Here, the outline of the production operation specified by the variation pattern command includes the production total time from the production start to the production end, and the result of winning or failing in the big hit lottery. In addition to these, the change pattern command including the presence or absence of the reach effect or the notice effect may be specified, but even in this case, the specific content of the effect content is not specified.

  Therefore, when the effect control unit 22 acquires the variation pattern command CMD, the effect lottery is subsequently performed, and the effect outline specified by the acquired variation pattern command is further specified. For example, the specific contents of the reach effect and the notice effect are determined. Then, in accordance with the determined specific game content, a lamp effect by blinking LED lamps or the like and a sound effect preparation operation by a speaker are performed, and an effect operation by a lamp or speaker is performed on the liquid crystal control unit 23. A control command CMD ′ relating to the synchronized symbol effect is output.

  In this case, the effect control unit 22 outputs a control command CMD ′ to the effect interface board 27 together with the strobe signal (interrupt signal) STB ′ for the liquid crystal control unit 23. In addition, when receiving the notification control command or other control command related to the liquid crystal display, the effect control unit 22 outputs the control command as it is to the effect interface board 27 together with the interrupt signal STB ′.

  Corresponding to the configuration of the effect control board 22, the effect interface board 27 is configured to receive an 8-bit control command CMD ′ and a 1-bit interrupt signal STB ′. These data CMD ′ and STB ′ are output to the liquid crystal control board 23 as they are via the buffer circuit 45.

  In addition, the effect interface board 27 receives the lamp driving control signals (DATA, CLOCK, ENABLE, LATCH) output from the effect control unit 22 and outputs them via the buffer circuit 46. The lamp drive control signal output from the effect interface board 27 is supplied to the LED lamp group such as the illumination display section 4 via the lamp connection board 34, and as a result, the control command CMD output from the main control section 21 is supplied. The corresponding lamp production is realized.

  FIG. 7 is a circuit diagram showing a connection relationship between the lamp connection board 34 and the circuit board 51 of the illumination display unit 4, and is configured by connecting a plurality of drivers Dr1, Dr2,... Drn in series. As shown in the figure, each driver Dri functions by receiving the serial signal DATA, the latch signal LATCH, the shift clock CLOCK, and the operation control signal ENABLE from the one-chip microcomputer 40 of the effect control unit 22. Although not limited in any way, in this embodiment, BD7851FP (see FIG. 8), which is a 16-bit constant current LED driver manufactured by ROHM, is used as the driver Dri.

  As shown in FIG. 7 and FIG. 8, in this embodiment, the serial signal DATA received from the one-chip microcomputer 40 of the effect control unit 22 is supplied to the 16-bit length shift register via the S_IN terminal, and the shift clock. Shifted in synchronization with CLOCK. And the serial signal which passed through the shift register is output from the S_OUT terminal.

  The serial signal DATA input to the shift register is acquired by the 16-bit latch register at the timing when the latch signal LATCH rises to H level. When the latch signal LATCH returns to L level, the acquired value of the latch register Is retained. The acquired value of the latch register is output as it is from the output terminals OUT1 to OUT16 if the operation control signal ENABLE is at L level. However, if the operation control signal ENABLE is at the H level, all of the open collector type output gate arrays are released.

  As described above, the six light emitters LUM are mounted on the circuit board 51 of the illumination display unit 4, and each of the light emitters LUM is composed of light emitting diodes LEDs of three primary colors RGB. In this embodiment, the driver Drn of the illumination display unit 4 uses only two sets (six) of the output terminals OUT1 to OUT6 among the sixteen output terminals, and for each light emitter LUM of each set. , Red R, green G, and blue B light emitting diodes are turned on / off in synchronization. Since the forward voltage drop VF of each diode is about 2V to 3.8V and the driving DC voltage is 12V, the current limiting resistor r1 is connected so that a current of about 20 mA flows correspondingly. .

  By the way, as described above, the absolute maximum ratings of each light emitting diode are about 100 mA in pulse forward current and about 5 V in reverse voltage, respectively. The absolute maximum rating of the driver Dri is about 0 to 7.0 V for the power supply voltage Vcc and about −0.3 to Vcc + 0.3 V for the input voltage. Therefore, for example, if an excessive voltage is applied to the power terminal Vcc of the driver Dri, the output terminals OUT1 to OUT6 of the driver Dri, or the power line VB (= 12 V) of the light emitting diode, each circuit element may be destroyed. .

  However, since the present embodiment employs the configuration for preventing the electrostatic discharge described above, the possibility that the light emitter LUM and the driver Dri are destroyed is greatly reduced. That is, as shown in FIG. 8B, a sufficient insulation distance is secured between the connection terminal T of the light emitter LUM and the protrusion BX, and the driver Dri and the current limiting resistor r1 are provided on the back surface of the circuit board. In addition, since there is no through hole at least in the range of the tip opening of the protrusion BX, the possibility of electrostatic discharge is reduced.

  In addition, since the present embodiment employs a configuration that prevents such electrostatic discharge, there is a possibility that discharge noise may be superimposed on the signal lines DATA, ENABLE, CLOCK, and LATCH routed from the effect control unit 22. And the abnormal operation of the light emitter LUM is effectively prevented. In addition, by disposing the driver and the current limiting resistor on the back side of the circuit board as in this embodiment, it is possible to freely arrange components without worrying about electrostatic discharge.

  As mentioned above, although the Example of this invention was described concretely, the concrete description content does not specifically limit this invention. For example, in the embodiment, the electrical display unit 4 is arranged at the peripheral part of the gaming machine, but may be arranged at the peripheral part or the lower position of the display device DISP, for example. In such a case, since the possibility of electrostatic discharge is increased by the charged game ball, the configuration of the present embodiment that prevents discharge functions more effectively.
