Description

  The present invention relates to a display substrate used in a gaming machine or the like.

  Conventionally, a display board using a light emitting diode is used in a gaming machine such as a swing type gaming machine. Hereinafter, a display substrate using a light emitting diode is also referred to as an LED (light emitting diode) substrate. FIG. 6 is a schematic front view of an LED substrate used in a conventional spinning cylinder game machine. The LED substrate 200 shown in FIG. 6 controls 20 color LEDs 201, 10 red LEDs 203, 15 current limiting resistors 205 for limiting the current flowing through the color LEDs 201, and the current flowing through the red LED 203. A current limiting resistor 207, a Zener diode 209 for protecting the light emitting element of the LED, and a connector 210 for connecting to a control board (not shown) for controlling the lighting of the LED board 200. Yes. Further, a white thin film (hereinafter also referred to as a masking film) 211 is formed on the surface of the LED substrate 200 by a masking process. The light emitted from the light emitting elements of the color LED 201 and the red LED 203 is radiated to the outside of the front of the gaming machine through a lens provided on the surface of each LED.

JP 2003-198092 A

  By the way, not all of the light emitted from the light emitting elements of the color LED 201 and the red LED 203 is emitted directly to the outside, but some percentage of the light emitted by the light emitting elements is caused by a lens or the like disposed on the front surface of the LED. The reflected light returns to the LED substrate 200, is reflected by the white masking film 211 applied to the surface of the LED substrate 200, and is emitted to the outside. However, in the conventional LED substrate 200, even if the white masking film 211 is formed, on the surface of the LED substrate 200, in addition to the LEDs, a large number of current limiting resistors 205, Zener diodes 209 which are LED protection elements, and the like Is arranged. For this reason, of the light reflected by the lens or the like and returned to the LED substrate, the light incident on these electronic components is not emitted outside but is wasted light. Therefore, the conventional LED substrate 200 has a problem that the reflection efficiency is poor.

  Further, as shown in FIG. 6, in the conventional LED board 200, since a large number of color LEDs 201 and red LEDs 203 are arranged on a narrow LED board 200, the current limiting resistors 205 have to be arranged close to each other. . However, when the current limiting resistors are arranged close to each other, the temperature of the LED substrate 200 and the like rises due to the heat generated by the current limiting resistors. For example, when five ¼ W current limiting resistors are arranged close to each other and connected in parallel, and the power consumption of each resistor is 0.27 W, the temperature of the current limiting resistor is about 60 °. C rises. Therefore, when the usage is performed when the ambient temperature is 40 ° C., the current limiting resistance is about 40 ° C. + 60 ° C. = 100 ° C., and the life is shortened compared to the normal usage. Furthermore, heat generated by a heat source such as a current limiting resistor arranged in the vicinity has been a cause of shortening the lifetime of a semiconductor element such as a light-emitting element that is particularly sensitive to heat.

  The present invention has been made based on the above circumstances, and provides a display substrate capable of improving the radiation efficiency of light to the outside and reducing the adverse effects of heat generated by a heat source. It is the purpose.

  In order to achieve the above object, a display substrate according to the first aspect of the present invention is formed on a surface, a thin film for reflecting light, a light source disposed on the surface, and a back surface. And an electronic component used for lighting control of the light source.

  In order to achieve the above object, a display substrate according to a second aspect of the present invention is the display substrate according to the first aspect, characterized in that the electronic components are distributed on the back surface.

  A display substrate according to a third aspect of the invention for achieving the above object is the display substrate according to the first or second aspect, wherein the light source uses a light emitting diode.

  In order to achieve the above object, a display substrate according to a fourth aspect of the present invention is the display substrate according to any one of the first to third aspects, wherein the electronic component limits a current flowing through the light source. It includes a current limiting resistor.

  To achieve the above object, a display substrate according to a fifth aspect of the present invention is the display substrate according to any one of the first to fourth aspects, wherein the thin film is a white resist film. And

  In the present invention, a light source is arranged on the front surface, and an electronic component used for controlling the lighting of the light source is arranged on the back surface, thereby increasing the surface area of the thin film formed on the surface for reflecting the light. The emitted light can be efficiently reflected and emitted to the outside. In addition, since the electronic parts used for the lighting control of the light source are distributed on the back surface, the electronic parts can be arranged at a sufficiently large interval. It is possible to reduce the adverse effect on the light source and the like due to the generated heat.

  The symbols arranged on each reel 11a, 11b, 11c include, for example, a red number “7” symbol, a blue number “7” symbol, a BAR symbol, a replay symbol, a watermelon symbol, a bell symbol, a cherry symbol, etc. is there. A total of 21 of these symbols are arranged on the outer periphery of each spinning reel 11a, 11b, 11c. Further, the number of symbols and the arrangement order of symbols differ for each of the spinning reels 11a, 11b, and 11c.

  The display window 12 is a transparent window provided at a position corresponding to the reel reels 11a, 11b, and 11c. As shown in FIG. 1, when the player stops the first reel reel 11a, the second reel reel 11b, and the third reel reel 11c, the player moves the reel reels 11a, 11b, and 11c from the display window 12. The three attached symbols can be visually observed.

  The medal slot 13 is an slot for a player to insert a medal (game medium). The inserted medal detection sensor 61 is provided inside the medal insertion slot 13 and detects that a medal has been inserted into the medal insertion slot 13. A detection signal from the inserted medal detection sensor 61 is sent to the main control board 70.

  A credit number display unit 14 is provided immediately below the display window 12. The credit number display unit 14 displays the medal credit number (stored number) within a predetermined range (for example, within 50 cards). When a medal is inserted from the medal slot 13, the main control board 70 counts and stores the number of credits increased from the current number of credits based on the signal from the inserted medal detection sensor 61. And displayed on the credit number display unit 14. Further, when a predetermined combination is established in the game, the main control board 70 adds the number of medals to be paid out corresponding to the combination to the current credit number, and displays the added number on the credit number display unit 14. Let

  The MAX bet button 15 and the single insertion button 16 are game instruction means for instructing to bet medals and play a game (game), and are provided on the lower left side of the display window 12. The MAX bet button 15 is a button for selecting to play a game with three medals, and the one-sheet insertion button 16 is for selecting to play a game with one, two or three medals. It is a button to do. Specifically, by pressing the single insertion button 16 once, it is selected to play a game with one medal, and by pressing the single insertion button 16 twice, a game with two medals bet Is selected, and by pressing the one-piece insertion button 16 three times, it is selected to play a game with three medals bet. In other words, pressing the single-load button 16 three times is the same as pressing the MAX bet button 15 once. The MAX bet button operation detection sensor 62 detects that the MAX bet button 15 has been pressed, and the one-sheet insertion button operation detection sensor 63 detects that the one-sheet insertion button 16 has been pressed. Detection signals from the sensors 62 and 63 are sent to the main control board 70. Thereby, the main control board 70 can recognize how many medals are bet to play the game.

  A bet number display section 17 is provided immediately below the left side of the display window 12. The bet number display unit 17 displays the number of medals bet in the game. Specifically, when the one-piece insertion button 16 is pressed once, the main control board 70 turns on the lamp corresponding to the “壱” portion of the bet number display section 17. When the one-sheet insertion button 16 is pressed twice, the main control board 70 turns on the lamp corresponding to the “弐” portion of the bet number display portion 17. When the one-sheet insertion button 16 is pressed three times or the MAX bet button 15 is pressed, the main control board 70 turns on a lamp corresponding to the “part” portion of the bet number display portion 17.

  In the present embodiment, six winning lines are set for stopping the three reel reels 11a, 11b, and 11c and aligning predetermined symbols. That is, three lines extending in the horizontal direction through each of the upper, middle and lower portions of the display window 12, lines extending from the upper left to the lower right of the display window 12, and from the lower left to the upper right of the display window 12. And a line extending from the middle of the left portion of the display window 12 toward the middle of the central portion and extending from the middle of the central portion toward the lower right. The effective winning line varies depending on how many medals are bet. When a game is played with one medal bet, only one winning line extending in the horizontal direction through the center of the display window 12 is an effective winning line. When a game is played with two medals bet, only three winning lines extending in the horizontal direction through the upper, middle and lower parts of the display window 12 are effective winning lines. When a game is played with three medals, all six pay lines are valid pay lines. When the three reel reels 11a, 11b, and 11c are stopped, when a predetermined symbol is aligned on an effective winning line among the six winning lines and a predetermined combination is established, the game is won, and a predetermined number of Medals are paid out.

  The start lever 18 is operated by the player to instruct to start the game. The operation of the MAX bet button 15 in a state where the required number of medals for one game (game) is inserted from the medal insertion slot 13 or the number of medals required for one game has already been credited. Alternatively, the start lever 18 can be operated by performing any one of the required operations of the single-load button 16. Here, one game starts when the start lever 18 is operated, and ends when all the three stop buttons 19a, 19b, and 19c are pressed. The start lever operation detection sensor 64 detects that the start lever 18 has been operated. When the start lever operation detection sensor 64 detects that the start lever 18 has been operated, it sends a game start signal to the main control board 70. The main control board 70 receives a game start signal from the start lever operation detection sensor 64 when receiving a signal from any one of the insertion medal detection sensor 61, the MAX bet button operation detection sensor 62, and the one-sheet insertion button operation detection sensor 63. When the game is received, the game start process is performed after a predetermined time (4.1 seconds) has elapsed since the last game start signal was received. Specifically, the main control board 70 acquires a random number value, performs a lottery process for a role based on the random number value, and starts rotating the three reel reels 11a, 11b, and 11c.

  The first stop button 19a is for instructing to stop the rotation operation of the first drum reel 11a, and the second stop button 19b is for instructing to stop the rotation operation of the second drum reel 11b. The third stop button 19c is for instructing to stop the rotation operation of the third drum reel 11c. The first stop button operation detection sensor 65a detects that the first stop button 19a is pressed, and the second stop button operation detection sensor 65b detects that the second stop button 19b is pressed. The third stop button operation detection sensor 65c detects that the third stop button 19c has been pressed. Detection signals from the respective stop button operation detection sensors 65a, 65b, 65c are sent to the main control board 70. When receiving the detection signals from the stop button operation detection sensors 65a, 65b, and 65c, the main control board 70 stops the rotation operation of the spinning reel corresponding to the stop button operation detection sensor by a predetermined control method. Thus, when the three spinning reels 11a, 11b, and 11c are stopped, a combination is established if the symbols attached to the spinning reels 11a, 11b, and 11c are in a specific combination on the effective winning line. Will do.

  The types of roles are roughly classified into big roles (bonuses) that are big hits and small roles that are big hits. For example, a big bonus (BB), which is a role when a red number “7” symbol or a blue number “7” symbol (BB symbol) is aligned on a valid winning line, In addition, there is a regular bonus (RB) that is a combination when the symbol “BAR” (RB symbol) is aligned on an effective winning line. When becoming a major player, the spinning-type gaming machine shifts to a gaming state advantageous to the player. For example, when BB is established, 15 medals are paid out, and the player enters a BB game where the player can acquire the largest amount of medals. When the RB is established, 15 medals are paid out, and after the BB game, the player enters an RB game where a large amount of medals can be obtained.

  On the other hand, the small role includes, for example, a role when watermelon symbols are aligned on an effective winning line (watermelon small role), and a role when bell symbols are aligned on an effective winning line (bell small role). , There is a role (cherry small role) when it stops at the left position on the winning line where the cherry symbol is valid. When such a small combination is established, a predetermined number of medals are paid out. In addition, there is a role (replay) when the replay symbols are aligned on a valid winning line. If this replay is established, the revolving game machine will automatically put in the re-playing state, that is, the same number of medals as the bet on the current game, and the player will not insert new medals. Then, the game can be played again. In this embodiment, since replay does not pay out medals, replay is not included in the small role, but setting of the number of bets for the next game, that is, no new medal insertion operation is required, Assuming that the used medals are paid out, it is possible to treat the replay as a small role. Further, if the symbols constituting the winning combination are not aligned on the effective winning line, the winning combination is lost.

  The number-of-payout display unit 22 displays the number of medals to be paid out in accordance with the established combination. The main control board 70 controls the payout number display unit 22. For example, when the player presses the clearing button 21, the number of medals corresponding to the number of credits at that time is released from the medal outlet 23. The medal tray 24 is a tray for accumulating medals discharged from the medal discharge port 23.

  The image display unit 30 is provided on the upper side of the display window 12. In the present embodiment, a liquid crystal display device is used as the image display unit 30. As shown in FIGS. 1 and 2, the image display unit 30 includes a liquid crystal panel 31 and a liquid crystal control board 32 that controls the liquid crystal panel 31.

  The three backlights are provided inside the first drum reel 11a, the second drum reel 11b, and the third drum reel 11c, respectively. These backlights are mounted on the backlight substrates 46a, 46b, and 46c, respectively, and are driven by a backlight drive circuit (not shown) mounted on the effect control substrate 80.

  Control of the illumination display unit 40 is performed by the effect control board 80 based on a command from the main control board 70. Specifically, the effect control board 80 generates a predetermined lighting command signal based on a command from the main control board 90 and sends it to each drive circuit.

  The cold cathode tube is provided inside the front door and above the display window 12. The cold-cathode tube not only plays a game, but also irradiates light to the spinning reels 11a, 11b, and 11c to improve the visibility of symbols printed on the spinning reels 11a, 11b, and 11c. Is also fulfilled. The drive circuit for the cold cathode tube mounted on the effect control board 80 includes an inverter circuit, a high voltage generation circuit, and the like. Upon receiving the lighting command signal, the driving circuit for the cold cathode tube drives the inverter circuit, generates a high voltage by the high voltage generation circuit based on the signal from the inverter circuit, and lights the cold cathode tube.

  The speaker unit 50 produces a game with sound. Control of the speaker unit 50 is performed by the effect control board 80 based on a command from the main control board 70. As shown in FIGS. 1 and 2, the speaker unit 50 includes a first door speaker 51, a second door speaker 52, and a rear speaker 53. The first door speaker 51 and the second door speaker 52 are provided on the left side and the right side of the upper part inside the front door, respectively. That is, in FIG. 1, the first door speaker 51 and the second door speaker 52 are circles drawn by dotted lines on the front door. Here, in the upper part of the front door, there is a gap between the portion where the top LED units 41a, 41b and 41c are provided and the portion where the image display unit 31 is provided, and the first door speaker 51 and the second door. Sound from the speaker 52 comes out through this gap. Further, the rear speaker 53 is provided on the back side of the swivel game machine.

  The main control board 70 mainly controls and manages game contents and medal payout. A plurality of integrated circuit elements are mounted on the main control board 70. Specifically, the main control board 70 includes a ROM 71, a RAM 72, and a CPU (game control means) 73 as shown in FIG. The ROM 71 stores various programs relating to game content control and the like. The RAM 72 is a working memory that temporarily stores data.

  The CPU 73 executes control of game content by executing a program stored in the ROM 71. For example, the CPU 73 performs a lottery process for a combination. Specifically, this lottery process is performed as follows. The ROM 71 stores a lottery table showing the correspondence between the combination and the random number value. When the CPU 73 receives a signal from the start lever operation detection sensor 64, the CPU 73 acquires a random value. Then, it is determined whether the acquired random number value corresponds to any combination in the lottery table, thereby determining whether the combination is incorrect or various types of combinations are selected. CPU 73 transmits a predetermined command to effect control board 80 in accordance with the lottery result.

  Further, the CPU 73 performs a reel control for driving and stopping the spinning reels 11a, 11b, and 11c. The reel control of the CPU 73 includes, for example, reel drive start control and reel drive stop control, as well as, for example, reel pull-in control performed when a winning combination is won, removal control performed when a winning combination is not won, and the like. is there.

  The reel pull-in control means that when a stop button is pressed, the symbol within the range of a predetermined number of frames (for example, 5 frames) from the symbol including the symbols on the winning line that is valid at the timing when the stop button is pressed. This means that when there is a symbol constituting a winning combination, the stop position of the spinning reel is controlled so that the symbol is drawn on the effective winning line. However, if there is no symbol that constitutes the relevant role within the range of the predetermined number of frames at the timing when the player presses the stop button, the reel pull-in control does not work, and the winning symbol is effective. Stop on line. Accordingly, at this time, the symbols constituting the winning combination are not aligned on the effective winning line, and the winning combination is not established.

  The off control means that the stop position of the reel is controlled so that no combination is established in the effective winning line. Therefore, in this case, even if the player presses the stop button aiming at a specific combination, no combination is established and the game result is lost.

  The CPU 73 also manages the gaming state. In the swivel type gaming machine of the present embodiment, the gaming state of the gaming machine is “a general gaming state when the BB is not operating”, “a BB internal state”, “an RB internal state”, or “a general game when the BB is operating”. Various game states such as “state” are set. The CPU 73 controls the transition of the gaming state based on the winning lottery result.

  Further, the CPU 73 performs processing for transmitting a command to the effect control board 80. There are many types of commands that are transmitted from the CPU 73 to the effect control board 80. For example, there are commands related to game effects (effect commands) created based on the result of the lottery process of the combination, commands (operation commands) created when a predetermined operation is performed by the player, and the like.

  In addition, various standards have been established for the spinning machine. One of the standards is that if 4.1 seconds have not elapsed since the start lever 18 was operated, the spinning reels 11a, 11b, and 11c do not rotate even if the start lever 18 is operated next time. For this reason, the CPU 73 performs drive start control of the spinning reels 11a, 11b, and 11c so as to conform to the standard. However, even if the start lever 18 is operated next within 4.1 seconds after the start lever 18 is operated, the CPU 73 detects the inserted medal detection sensor 61, the MAX bet button operation detection sensor 62, one piece. If a signal has already been received from any of the input button operation detection sensors 63, a lottery process based on a random number value is performed.

  The effect control board 80 mainly performs control related to game effects. A plurality of integrated circuit elements are mounted on the effect control board 80. Specifically, the effect control board 80 includes a ROM 81, a RAM 82, and a CPU (effect control means) 893, as shown in FIG. The ROM 81 stores various types of data such as various programs relating to control of game effects, image effect pattern data, electrical effect pattern data, audio data, and the like. The RAM 82 is a working memory that temporarily stores data.

  The CPU 83 controls the image display unit 30, the electrical display unit 40, and the speaker unit 50 by executing a program stored in the ROM 81. Specifically, when receiving an effect command from the main control board 70, the CPU 83 determines the contents of the effect of the game based on the effect command. Then, the CPU 83 reads image effect pattern data corresponding to the determined content from the ROM 81 and sends it to the image display unit 30. Thereby, the image display unit 30 controls the display of the image based on the image effect pattern data.

  Further, the CPU 83 reads the illumination effect pattern data corresponding to the determined content from the ROM 81, and then generates a predetermined lighting command signal based on the illumination effect pattern data. Then, the CPU 83 sends the generated lighting command signal to a drive circuit such as an LED or a backlight. Although not shown, the drive circuit is provided on the effect control board 80. A drive circuit, for example, a LED drive circuit, controls lighting of each LED unit mounted on the LED boards 44a, 44b, 44c, 45a, 45b,..., 45h based on the lighting command signal. Similarly, the backlight driving circuit controls lighting of each backlight, and the cold cathode tube driving circuit controls lighting of the cold cathode tube. Further, the CPU 83 reads out predetermined audio data from the ROM 81 based on the determined content, and then sends it to the speaker unit 50. As a result, sound is output from the speaker unit 50.

Next, the LED board whose lighting is controlled by the effect control board 80 will be described. In the present embodiment, various LED boards 44a to 44c, 45a, 45b to 45h are arranged. Since all LED boards have the same characteristics, the top LED board 44c will be exemplified below. I will explain. Hereinafter, the top LED substrate 44c is also simply referred to as an LED substrate 44c. FIG. 3 is a schematic front view showing an example of the LED substrate 44c of the present embodiment, and FIG. 4 is a schematic back view thereof. In addition, the schematic back view shown in FIG. 4 has shown the arrangement | positioning state of the electronic component arranged on the back surface when the LED board 44c is seen through from the front in order to simplify description. Moreover, LED substrate 44c shown in FIG. 3, when actually mounted in the game machine, a color LED 101 ₂₀ and red LED 103 ₁₀ is located, the wider the substrate end portion of the width above, narrower width Attach to the gaming machine with the end of the board facing down.

On the surface of the LED substrate 44c of the present embodiment, a light reflecting thin film (hereinafter, this thin film is also referred to as a resist thin film) 111 using a white resist as a masking agent is formed.
