Description

  The present invention relates to a decorative display device provided in a gaming machine such as a pachinko machine.

  Traditionally, decorative displays using light sources such as lamps and LEDs (light-emitting diodes) have been added to pachinko machine frames and slot machine casings to light up and flash according to the gaming state to enhance the effect. For example, a light source is used as a backlight to indirectly illuminate the design pattern on the front surface of the decorative display device, or the light source is matched to the design pattern on the front surface of the decorative display device. A method of arranging and directly illuminating the design pattern is taken.

  Here, when the light source is used as a backlight, since it is indirect illumination, it does not give satisfactory and sufficient expressive power and appeal power. In addition, when the decoration display device is directly illuminated, the lamp and the LED are exposed, so that the color becomes bright, but a complicated structure in which a light source is arranged on the surface or inside of the decoration display device is adopted. Therefore, the light source cannot be installed well in accordance with the design pattern, and the design is unsatisfactory. This also does not give satisfactory and sufficient expressive power and appeal.

  Therefore, in recent years, in view of these problems, an EL display device capable of emitting predetermined characters and numbers using an EL (electroluminescence) element is provided on the frame and the housing to improve the decoration effect. A gaming machine has been proposed (see, for example, Patent Document 1). By using such an EL display device, it is possible to configure a thin decorative display device that is easy to use, and it is also possible to directly illuminate the design pattern of the decorative display device according to its shape. .

  When assembling the LED board 70, first, the terminal of the red LED 71a is inserted into the base board 73, and then the LED mounting board 72 is put on the red LED 71a and the LED mounting board 72 is brought into contact with the base portion of the red LED 71a. Thereafter, the terminal of the blue LED 71b is passed through the corresponding hole from above the LED mounting substrate 72, and the LED mounting substrate 72 is pressed from above by the body of the blue LED 71b. In this state, the terminals of the LEDs 71a, 71b, 71c are soldered and fixed to the wiring pattern on the back surface of the base substrate 73.

  Accordingly, the LED mounting substrate 72 and the base substrate 73 can be held in a stacked state without providing a separate mounting member. Further, since the blue LED 71b and the green LED 71c have their terminals passing through both the LED mounting substrate 72 and the base substrate 73, they are more firmly attached to the base substrate 73. That is, the LED mounting substrate 72 has a function of firmly mounting the LED 71 to the LED substrate 70.

  Further, a reflective layer 74 capable of reflecting the light of the LED 71 is provided on the surface of the LED mounting substrate 72. The reflective layer 74 is not particularly limited as long as it can reflect light. For example, the reflective layer 74 may be formed by performing metal plating such as solder on the conductor layer on the substrate.

  As for the type of the LED 71, it is preferable to appropriately select the luminance and directivity according to the length of the display plate (light guide plate) 55. Generally, if the length of the display plate 55 is short (for example, 20 cm or less), the viewing angle is reduced. As a thing of about 45 to 60 degree | times, it does not need to be a high brightness type. Furthermore, in this case, since the pitch of the LEDs 71 can be designed wider (for example, 2 cm or more), the cost is reduced.

  On the other hand, if the length of the display plate 55 is long (for example, 40 cm or more), in order to ensure an appropriate amount of light at the other end, for example, a high-luminance type having a viewing angle of about 20 to 35 degrees. preferable. In this case, it is desirable to reduce the pitch of the LEDs 71 (for example, 1 cm or less). In this way, the emission intensity of the display plate 55 can be maintained while reducing the cost as much as possible.

  6A is a plan view showing a state in which the LED substrate 70 is installed in the receiving portion 62 (base guide piece 63), and FIG. 6B is a view in the receiving portion 62 (base guide piece 63). It is a front view which shows the state which installed the LED board. FIG. 6B shows a state in which the front plate (portion indicated by a two-dot chain line) of the base guide piece 63 and the side guide pieces 64a and 64b is removed. As shown in FIG. 6, the LED board 70 is in a state of being fitted between the stopper pieces 47a and 47b, and in this state, heat when the LED board 70 is turned on is established in the back plate 65. It is discharged from the notch 68 to the outside.

  Note that the wire harness 67 protruding from the back surface of the receiving portion 62 is a cable for electrically connecting the LED board 70 built in the receiving portion 62 and a later-described lamp control circuit 37 installed in the gaming machine 1. It is. Further, in the drawing, the cutout 68 at the right end is a passage opening for the wire harness 67 (see FIG. 3B). In the figure, reference numeral 77 denotes a male connector connected to the female connector 75, and the wire harness 67 is connected to the male connector 75.

  FIG. 7 is a front view showing the decorative display device 50 with the display plate 55 attached to the base guide piece 63 together with its internal structure. Since the lower end 54 of the display plate 55 abuts against the stopper pieces 47a and 47b, a slight clearance is secured between each LED 71 of the LED substrate 70 and the lower end 54 of the display plate 55.

  FIG. 8 is an exploded perspective view of the display plate 55, the reflective tape 56, and the reflective sheet 58. A reflective tape 56 is attached to the peripheral portion of the display plate 55, and a reflective sheet 58 is attached to the back side of the display plate 55. The reflective tape 56 is not formed on the lower end 54 of the display plate 55 where the LED 71 faces.

  The reflection sheet 58 may be a sheet colored in white or glossy color. Further, the reflection sheet 58 may be provided only on the portion overlapping the pattern (printing unit) 60, and a desired background color may be applied to other portions. That is, the reflection sheet 58 may be at least in a portion overlapping the pattern (printing unit) 60 in order to improve the light emission intensity of the pattern (printing unit) 60.

  The reflective tape 56 may be a tape colored white or glossy like the reflective sheet 58. As a result, the light passing through the inside of the display plate 55 is reflected at the boundary with the outside world to prevent leakage to the outside, and the light emission intensity of the pattern (printing unit) 60 is improved.

  The display plate 55 as a light guide plate is formed with a thickness of about 5 mm, and on the back side (the reflection sheet 58 side), a printing portion (FEVER character) 60 as a pattern (light emitting portion) that diffuses light. Is screen printed. The paint (ink) used for this printing has diffuse reflection characteristics and contains a scattering material. Examples of the material include pearl materials, glass, bead pigments, white pigments, and diffusibility and color development. An organic fluorescent derivative and a non-organic compound may be added to improve the emission intensity.

  Specifically, transparent organic resin particles such as silicone resin particles and polystyrene resin particles, metal oxide particles such as Al2O3, TiO2, and SiO2, sulfate particles such as BaSO4, carbonate particles such as CaCO3, fine glass powder and glass Examples include inorganic compound particles such as balloons, micro air cells, and the like, and these can be used alone or in combination of two or more.

  In consideration of the reflection efficiency, the printability of the paint, etc., the average particle diameter of the particles of these materials is preferably about 0.01 to 20 μm, particularly about 0.05 to 1 μm, and is contained in the light reflecting layer. The amount is preferably about 0.5 to 50% by weight, particularly about 3 to 20% by weight. As the coating material, a thermosetting resin such as an acrylic resin, a urethane resin, or an epoxy resin, or an acrylic, rubber-based, or elastomer-based pressure-sensitive adhesive can be used.

  In addition to screen printing, printing methods such as offset printing, gravure printing, letterpress printing, pad printing, and ink jet printing can be employed. Preferably, printing is performed in an inline manner in the molding process of the display plate 55. Good. Also, if the printing thickness is excessively thin, the light reflection efficiency is not sufficient, and conversely, even if it is excessively thick, there is no significant difference in the light reflection efficiency. Therefore, it is preferable to select appropriately considering these, and it is usually preferable to set the thickness to about 20 to 200 μm.

  Moreover, as a material of the light guide plate constituting the display plate 55, a transparent material having a high refractive index is used, and methacrylic resin (PMMA), acrylic resin, etc. are preferable. Can be appropriately selected according to, for example, polystyrene, styrene-methyl methacrylate copolymer, polymethylpentene, allyl glycol carbonate resin, spirane resin, amorphous polyolefin, polycarbonate, polyamide, polyarylate, polysulfone, polyallylsulfone, Polyethersulfone, polyetherimide, polyimide, diallyl phthalate, fluororesin, polyester carbonate, norbornene resin (ARTON), alicyclic acrylic resin (Optretz), silicone resin, aluminum resin Rirugomu include a transparent material such as silicone rubber.

  In addition, the light guide plate (methacrylic resin, acrylic resin) can be produced by cell casting or extrusion. Extrusion plates have a lower molecular weight than cast plates due to differences in the manufacturing process, and their physical properties are heat resistant and impact resistant. -Although the surface hardness is slightly inferior, there is an advantage that it is easy to thermoform, and this manufacturing method may be appropriately selected according to the purpose. In this embodiment, a cast plate is used.

  As described above, the display plate 55 can form the light emitting portion 60 that is a pattern of diffusing light by printing, and therefore, various characters and designs in any color can be adopted very easily as the light emitting portion. In addition, it is good to make it print at intervals of about 1.5-2 cm from the lower end 54 of the display plate 55 which LED71 faces. This is because the printing unit 60 does not emit light neatly due to the directivity of the LED 71 if printing is performed too close to this end face.

  When it is desired to change the pattern 60 of the decorative display device 50, the display plate 55 with the existing pattern 60 is removed from the receiving portion 62 by removing the screw, and then the display plate 55 with the new pattern 60 is applied. Is inserted into the receiving portion 62 until it comes into contact with the stopper pieces 47a and 47b, and the new display plate 55 is fixed to the receiving portion 62 again with screws.

  Furthermore, since the pattern 60 is only printed on the display plate 55, even when the new pattern 60 is applied to the display plate 55, it can be performed very easily and inexpensively. Furthermore, since the decorative display device 50 is formed on substantially the same plane as the glass door frame 17, there is no risk of damage or failure due to collision with anything, and even if it collides, the display plate 55 is durable. Since it is formed of a light guide plate (methacrylic resin, acrylic resin), it is possible to prevent or minimize damage or failure.

  9A and 9B show the relationship between the directivity of the LED 71 and the irradiation area. When attention is paid to the red LED 71a in FIG. 9A, light does not reach the portion indicated by the hatched portion 59 directly from any of the red LEDs 71a. Since there is a large difference in brightness between the portion where the direct light reaches and the portion where the light does not reach, streaks of light occur. Therefore, it is preferable to design the hatched portion 59 where direct light does not reach within the base guide piece 63 so as to cover the streak of light with the base guide piece 63. In the decorative display device 50 shown in FIG. 7, similarly to FIG. 9A, the lower end 54 of the display plate 55 enters several cm inside the base guide piece 63, and the base guide piece 63 is a blindfold that hides the streak of light. It functions as a member.

  Further, as shown in FIG. 9B, even when the range 59 where the direct light from the LED 71 does not reach all fits in the base guide piece 63, the pattern 60 may be printed while avoiding the range 59. Therefore, the pitch and directivity (viewing angle) of the LEDs 71, the width of the base guide piece 63, and the like may be designed in consideration of matters such as the influence of light streaks and the size of the range where pattern printing should be avoided.

  Note that the thickness of the display plate 55 may be other than 5 mm, and is preferably in the range of about 3 to 7 mm. If it is less than this range (less than 3 mm), the emission intensity decreases. On the other hand, if this range is exceeded (more than 7 mm), the emission intensity is not a problem, but the display plate 55 becomes thick, bulky, or heavy. Therefore, it is not preferable in handling.

  FIG. 10A shows a propagation path of light incident from the LED 71 inside the display plate 55, and FIG. 10B shows a state in which the light incident from the LED 71 is reflected by the printing unit 60. The light emitted from the LED 71 passes through the inside of the display plate 55 as shown by the incident light 51 as an example, and the incident light 51 that has reached the edge of the display plate 55 is reflected by the reflective tape 56 and again displayed on the display plate. 55 is passed through. Then, when the incident light 51 reaches the printing unit 60 in the process of following such a path, diffused reflected light 52 as shown in FIG. 10B is generated by the diffuse reflection characteristic, and this light is displayed on the display plate 55. The printing unit 60 appears to emit light. The end face 54 of the display plate 55 facing the LED 71 is preferably subjected to buffing (polishing ... mirror finish), which further increases the light emission intensity of the pattern (printing portion) 60.

  FIG. 11 schematically shows how the pattern (printing unit 60) of the decorative display device 50 emits light. Since the entire display plate 55 does not shine but only the pattern (printing unit 60) on the display plate 55 shines, a high decorative effect can be obtained.

  By the way, the emission color of the pattern (printing unit) 60 is determined by the printing color of the printing unit 60 and the emission color (wavelength) of the LED 71. That is, if the printing color of the printing unit 60 is colorless or white, the emission color of the LED 71 is almost the emission color of the pattern (printing unit 60). If the printing color of the printing unit 60 is colored, a color obtained by almost mixing the printing color of the printing unit 60 and the emission color of the LED 71 becomes the emission color of the pattern (printing unit 60). If the emission color of the LED 71 is white, the printing color of the printing unit 60 is almost the emission color of the pattern (printing unit 60).

  FIG. 12 is an explanatory diagram showing a relationship between the combination of the emission color (wavelength) of the LED 71 and the printing color of the pattern (printing unit) 60 and the emission intensity of the printing unit 60. In the figure, “A” indicates that the emission intensity is strong, “B” indicates that it is slightly strong, “C” indicates that it is slightly weak, “D” indicates that it is very weak, and “E” does not emit light. Represents.

  The emission intensity of the pattern (printing unit) 60 depends on both the emission color (wavelength) of the LED 71 and the printing color of the printing unit 60. When the printing color of the printing unit 60 is black (or a color close to that), the color is black regardless of the emission color of the LED 71, and the pattern (printing unit 60) emits little light. Further, when the emission color of the LED 71 and the printing color of the printing unit 60 are the same, the emission intensity is high, and the emission intensity becomes weaker as the emission color of the LED 71 and the printing color of the printing unit 60 approach the complementary color relationship.

  For example, when the color of the LED is “red” and the printing color is “green” or “blue”, the emission intensity is “D” because the relationship is complementary or close to complementary. In addition, when the LED color is “blue” and the print color is its complementary color “red”, the emission intensity is slightly weaker “C”. Therefore, if a blue pattern and a red pattern are printed on the display plate 55 and the color of the LED to be lit is switched between blue and red, only the red pattern emits light when the red LED is lit, and the blue LED Since only the blue pattern emits light when lit, the light emission location is switched, and a variety of decorative effects can be obtained.

  As shown in FIG. 1, the gaming machine 1 configured as described above is configured such that a game ball is first fired from a ball hitting device 43 by a player's operation of the ball hitting operation handle 2, and a ball hitting guide rail 3 and a game area forming rail. A game ball is launched into the game area 5 of the game board 6 through 4. Then, the game ball falls in the game area 5 by its own weight, and in the process of falling, the game ball 5 is changed in the direction of dropping by a game nail or a windmill 20 (not shown) implanted in the game area 5, In the case where the normal winning opening 14 is won, the normal symbol operating gate 19 is passed, or all the winning holes are not won, the winning hole 16 is collected.

  When a game ball wins the start winning opening 11, a predetermined prize ball is given to the player, and the game ball is detected by a start opening sensor 32 (see FIG. 13) to be described later. After the special symbols are displayed on the symbol display sections 8, 9, and 10 for a predetermined time (scroll display), the left symbol display section 8 is first stopped, then the middle symbol display section 9 is stopped, and finally the right symbol display section. A jackpot lottery (hereinafter also referred to as a jackpot lottery game) in which 10 is stopped and displayed is performed.

  Then, in the special symbol display device 45, a special symbol combination (for example, the same special symbol combination) constituting a big hit when the special symbol of the left symbol display unit 8 and the special symbol of the middle symbol display unit 9 are stopped. In this case, the reach is reached, and a predetermined reach action is displayed on the special symbol display device 45, and then the special symbol that is confirmed and displayed when the special symbol on the right symbol display unit 10 stops is determined in advance. In the case of a combination of special symbols (a jackpot symbol, for example, a combination of the same special symbols), a big hit is made, and a jackpot game for opening an attacker as a big prize opening 7 in a predetermined manner is executed. In the case of a combination of special symbols other than these, they are out of sync.

  Further, when the game ball wins the normal winning opening 14, a predetermined prize ball is given to the player. Further, when the game ball passes through the normal symbol operating gate 19, the normal symbol display device 18 displays the normal symbol in a variable manner, the lottery is performed, and the confirmed normal symbol is a predetermined normal symbol. The winning winning opening (electric tulip) 11 is opened for a predetermined time.

  Here, in the gaming machine 1 of the present embodiment, the numbers “1” to “14” are displayed as special symbols on the symbol display portions 8, 9, and 10, and reach as a combination of special symbols. When “1, 1” to “14, 14” are displayed on the left symbol display unit 8 and the middle symbol display unit 9, each symbol display unit 8 becomes a big hit as a combination of special symbols. , 9 and 10, the jackpot symbols “1, 1, 1” to “14, 14, 14” are displayed.

  In addition, among the jackpot symbols, the odd numbered numbers (“1, 1, 1”, “3, 3, 3”, “5, 5, 5”, “7, 7, 7”, “9, 9, 9”, “11” , 11, 11 ”,“ 13, 13, 13 ”) is a specific big symbol, an even number of numbers (“ 2, 2, 2 ”,“ 4, 4, 4 ”,“ 6, 6, 6 ”,“ 8 ”) , 8, 8 ”,“ 10, 10, 10 ”,“ 12, 12, 12 ”,“ 14, 14, 14 ”) is usually a big bonus symbol, and the specific big bonus symbol is more for the player than the normal big bonus symbol. An advantageous special game is awarded.

  That is, when a specific big win symbol is confirmed and displayed, as a special game, until a predetermined number (for example, 100) of big win lottery games is exhausted after the specific big win symbol is confirmed and displayed, or the next big hit Until it comes, the probability of winning a lottery (hereinafter referred to as “hit probability”) will increase and the probability of winning a normal symbol (hereinafter also referred to as “hit probability”) will increase, reducing the fluctuation time of normal symbols. Then, a so-called probability variation game is provided that extends the opening time of the start winning opening 11 and shortens the variation time of the special symbol. On the other hand, when the normal big winning symbol is confirmed and displayed, as a special game, a so-called short-time game in which there is no increase in the big hit probability in the probability variation state is given.

  Next, the main control circuit 25 provided on the back side of the gaming machine 1 (inner frame 21) will be described with reference to FIG. FIG. 13 is a principal block diagram of a control system provided in the gaming machine 1 of the present embodiment. The main control circuit 25 includes a one-chip microcomputer 26, an input / output circuit 27, and the like. The one-chip microcomputer 26 includes a CPU 29, a RAM 30, a ROM 31 and the like therein.

  The one-chip microcomputer 26 is connected to various control circuits, various drive devices, various switches and the like via an input / output circuit 27. That is, the input / output circuit 27 includes a start opening sensor 32 provided for the start winning opening 11 and other winning sensors (for example, a normal symbol start switch for detecting passage of a game ball to the normal symbol operation gate 19). It is connected.

  A relay circuit 33 is connected to the input / output circuit 27. The relay circuit 33 has a solenoid 34 for opening the grand prize opening 7, a count sensor 35 for detecting a game ball won in the big prize slot 7, A specific area sensor 36 for detecting the passage of the game ball to the specific area 15 provided in the winning opening 7 is connected. Further, the input / output circuit 27 includes a decoration display device 50 which is a main part of the present invention, LEDs (for example, the hold LED 22 and the hold LED 23) and various display lamps (for example, the game effect lamp 15) provided on the game board surface. ) And the like, a voice control circuit 38 that performs voice control for amplifying various sound effects from the speaker 39, and other solenoids (for example, a start winning opening (electric tulip) 11). Solenoid to be connected).

  The input / output circuit 27 is connected to a payout control circuit 40 and a display control circuit 44. The payout control circuit 40 includes a control CPU (not shown), a RAM having a storage area for holding and storing a work area of the CPU, the number of prize balls corresponding to each prize ball command, control data, A ROM or the like in which a control program for paying out a prize ball is stored is provided. The payout control circuit 40 drives and controls the prize ball payout device 41 in accordance with the prize ball command instructed from the main control circuit 25, and performs prize ball payout control. The payout control circuit 40 is connected to the main control circuit 25 as described above, and is connected to a hitting ball launching device 43 for firing a pachinko ball toward the game area 5 via the launch control circuit 42. The operation stop / operation stop release of the hit ball launching device 43 is controlled.

  The display control circuit 44 is connected to a special symbol display device 45 and a normal symbol display device 46. The display control circuit 44 stores therein a display control CPU (not shown), a RAM having image data and a work area by the CPU, display control data corresponding to each command, characters and symbols. ROM etc. are provided.

  When the display control circuit 44 receives a strobe signal from the main control circuit 25, the CPU recognizes a display control command. Display control data and characters and symbols are read from the ROM from the data area corresponding to the display control command and stored in the RAM for storing image data. When the stored image data is displayed, the image data is read from the RAM and displayed on the liquid crystal display panel (special symbol display device 45).

  FIG. 14 is a flowchart showing a decoration display device display process executed by the CPU 29 of the main control circuit 25. Immediately after the power is turned on, the CPU 29 performs initialization processing, and initializes flags, registers, and storage areas necessary for stack setting and the following processing. Thereafter, when the process proceeds to the decoration display device display process, the CPU 29 controls the lighting of the decoration display device 50 in various modes according to various game states of the gaming machine 1. The decoration display device display process is repeatedly executed at a predetermined cycle (several milliseconds).

  First, the symbol variation display processing in step S10 is to display the decoration display device 50 in a predetermined symbol variation lighting pattern when the special symbol display device 45 displays the big hit lottery game, and the big hit lottery game is displayed. If not, the CPU 29 proceeds to the jackpot display process of step S20. This jackpot display process is to display the decoration display device 50 in a predetermined jackpot lighting pattern when the jackpot game is being executed. When the jackpot game is not being executed, the CPU 29 shortens the time of step S30. Transition to display processing.

  This short time display process displays the decoration display device 50 in a predetermined short time lighting pattern when the short time game is being executed. When the short time game is not being executed, the CPU 29 performs step S40. Moves to probability change display processing. This probability variation display process displays the decoration display device 50 in a predetermined probability variation lighting pattern when the probability variation game is executed. When the probability variation game is not performed, the CPU 29 performs step S50. Transition to normal display processing. In the normal display process, when any of the steps S10 to S40 of the decoration display device display process is not executed (including a case where a game is not executed by the player), the decoration display device 50 is set to a predetermined normal display process. The lighting pattern is displayed. In other words, the decoration display device 50 performs any one of the steps S10 to S50 of the decoration display device display process, so that the symbol variation lighting pattern, the big hit lighting pattern, the short time lighting pattern, the probability variation lighting pattern, and the normal lighting pattern are displayed. One of the lighting patterns is displayed.

  In addition, although the lighting aspect of these lighting patterns is not specifically limited, For example, you may make it as follows. The symbol variation lighting pattern is based on red slow blinking (for example, blinking cycle 1 second), and when reaching the reach state, blue and green alternately blink rapidly (for example, blinking cycle 80 msec). The big hit lighting pattern is a slow orange blink (for example, a blink cycle of 1.2 seconds). The short-time lighting pattern is light blue blinking at a low speed (for example, blinking cycle 1.4 seconds). The probability variation lighting pattern is a slow purple blink (for example, a blink cycle of 1.6 seconds). The normal lighting pattern is an alternating gradation of red, blue, green, orange, purple, and light blue (a mode in which light is gradually turned on or off, so-called fade-in / fade-out, for example, a lighting cycle of 8 seconds).

  In this way, the decoration effect and the production effect of the gaming machine 1 are enhanced, and the player can recognize the current gaming state based on the lighting color or blinking cycle of the decoration display device 50. become. In addition, orange is colored by simultaneous lighting of the red LED 71a and the green LED 71c, purple is colored by simultaneous lighting of the red LED 71a and the blue LED 71b, and light blue is colored by simultaneous lighting of the blue LED 71b and the green LED 71c. The types of lighting patterns or lighting colors are not limited to those described above. For example, the colors may be increased by simultaneously lighting the red LED 71a, the blue LED 71b, and the green LED 71c. The color can be adjusted infinitely by changing the combination of LEDs to be lit and the emission intensity of each LED. For example, the light emission intensity can be adjusted by controlling the value of the current passed through the LED 71 and the on-time with a resistance value or software.

  Furthermore, when the reach state occurs during the display of the short time lighting pattern or the probability variation lighting pattern, the symbol variation lighting pattern may be displayed with priority. This further increases the interest of the game. In this case, the lighting color indicating the reach state may be fast flashing red when the time is short and green when the probability is changed. This is because the light blue that is lit when the time is short is colored by two of the blue LED 71b and the green LED 71c, the difference in color increases by making red not used for light blue color development, This is because the lighting color indicating the reach state can be made conspicuous. Therefore, when the probability is changed (purple), the lighting color indicating the reach state is set to green for the same reason. By making the difference in color conspicuous in this way, the decoration effect and the production effect are enhanced.

  FIG. 15 is a perspective view showing another example of the display plate 55. In other embodiments described below, the same reference numerals are given to the same configurations as those described above. So far, a pattern having a property of diffusing light is formed directly on the display plate 55 by printing, but in this example, a film sheet 78 on which a pattern (light emitting portion) 60 that diffuses light is printed is displayed on the display plate ( The light guide plate 55 is attached to the light guide plate 55. The film sheet 78 is a film-like sheet cut into the same shape as the display plate 55.

  In this case, the pattern (light emitting part) 60 may be printed on the back side of the film sheet 78 (on the side opposite to the sticking surface to the display plate 55). The reason for this is that the display plate 55 and the film sheet 78 can be adhered and adhered so that there is no gap, thereby increasing the light emission intensity of the pattern.

  FIG. 16 is a perspective view showing still another example of the display plate 55. Here, the cutting sheet 79 obtained by cutting the film sheet on which the pattern (light emitting unit) 60 is printed into the shape of the pattern is adhered to the display plate 55. Also in this case, for the same reason as described above, the pattern (light emitting portion) 60 may be printed on the back side of the cutting sheet 79.

  When the pattern is provided on the back side, a colored transparent or colorless transparent film sheet 78 and cutting sheet 79 are used. When the pattern is provided on the surface side, the film sheet 78 and the cutting sheet 79 may be opaque, and the film sheet 78 and the cutting sheet 79 themselves may have a function of producing a background color or a function as a reflecting material. Good.

  If a film sheet on which a pattern is printed as shown in FIGS. 15 and 16 is attached to the display plate 55, the design of the decorative display device 50 may be peeled off or pasted (sheet or cutting sheet). This makes it very easy to make changes, which leads to cost reduction when changing the design. In particular, in the cutting sheet 79, various designs can be formed by changing the combination of a plurality of cutting sheets 79 and the arrangement when pasting on the display plate 55.

  Even when the pattern is directly printed on the display plate 55, the plate material (light guide plate) can be recycled by deleting the original printing and printing a pattern with a new design.

  FIG. 17 is a perspective view showing still another example of the display plate 55. In this example, the shape of the display plate is a display plate 155 in which the central part is formed in a substantially semicircular curved surface. That is, the display plate 155 is formed by a flat portion 152 formed at the upper and lower portions thereof and a curved surface portion 151 formed at the central portion thereof, and the pattern (light emitting portion) 60 is formed on the upper flat portion 152 and the curved surface portion 151. Each is formed. Therefore, when the display plate 155 is manufactured, first, printing (printing for the curved surface portion 151 and printing for the flat surface portion 152) is performed on the back surface of the flat light guide plate, and then the central portion is substantially semicircular. You just need to process the song. Note that the reflective tape 56 and the reflective sheet 58 described above may be attached to the display plate 155.

  Since the heat treatment is generated in the bending process, it is preferable here to employ an extruded plate (methacrylic resin, acrylic resin) manufactured by an extrusion manufacturing method that facilitates thermoforming as the light guide plate. However, as described above, the extruded plate is inferior in impact resistance, surface hardness, and the like as compared with the cast plate. Here, in consideration of these, the display plate 155 has scratches that protect the surfaces of the curved surface portion 151 and the flat surface portion 152. An anti-stick coating 147 is provided. Note that the scratch-preventing coating 147 may be mixed with a photocatalyst (titanium oxide) that decomposes dirt.

  The LED substrate 70 is attached to the receiving portion 162 in the same manner as shown in FIG. 6 and is configured to irradiate light from the lower end surface 149 of the display plate 155. However, the receiving portion 162 is different from the above-described shape, that is, the side guide pieces 164a and 164b are formed vertically. Therefore, when the display plate 155 is attached to the receiving portion 162, the lower plane portion is provided. It is necessary to fix the display plate 155 to the receiving portion 162 with screws or the like after fitting the receiving portion 152 to the receiving portion 162. Moreover, it is preferable that the stopper pieces 47a and 47b provided on the inner sides of the left and right ends of the base frame 163 are formed to have a smaller lateral width than that described above. This is because the light incident on the display plate 155 reaches the left and right ends.

  Accordingly, when the decorative display device 150 having the display plate 155 configured as described above mounted on the receiving portion 162 as described above is attached to the gaming machine 1, the light emitted from the LED is reflected by the curved surface portion 151. It propagates through the inside of the display plate 155 along a substantially semicircular shape formed by the flat surface portion 152, and not only the pattern (light emitting portion) 60 of the flat surface portion 152 but also the pattern (light emitting portion) 60 of the curved surface portion 151. Also emits light. In other words, the decorative display device 150 can adopt not only a flat surface but also a curved display plate 155, so that it can be conspicuous in the periphery and a high decorative effect can be obtained. In addition, you may make it provide the decoration board etc. which hide the clearance gap between the curved surface part 151 and the glass door frame 17 surface on the both right and left sides of the decoration display apparatus 150. FIG.

  FIG. 18 is a perspective view showing another example of the decoration display device 50. In this example, the decoration display device 250 formed separately is attached to the gaming machine 1 instead of the decoration display device 50 formed integrally with the gaming machine 1. The decorative display device 250 includes a frame 262 and a display plate 255. The frame 262 includes a base frame 263, left and right side frames 264a and 264b, and a back plate 265, and the base frame 263 and the side. The frames 264a and 264b form a substantially U-shaped frame as a whole.

  The frame 262 is configured such that the display plate 255 is fitted from below along the guide grooves of the left and right side frames 264a and 264b with the U-shaped open portion facing downward. That is, the frame 262 has the same rectangular cavity as the display plate 255 to which the display plate 255 is mounted, and only the surface thereof is formed in a substantially U shape by the base frame 263 and the side frames 264a and 264b. ing.

  The LED substrate 70 is attached to the base frame 263 of the frame 262 in the same manner as shown in FIG. 6 and is configured to irradiate light from the upper end 154 of the display plate 255. That is, the decorative display device 250 is configured to irradiate light from the lower end 156 side of the display plate 255, and therefore, the lower end 156 of the display plate 255 is emitted from the lower end 156 without attaching a reflective tape. The decorative effect is enhanced by the transmitted light 233 (see FIG. 19). For this reason, the buff (polishing: mirror finishing) described above is applied not only to the upper end portion 154 side but also to the lower end portion 156 side, thereby increasing the transmitted light 233. However, the emission intensity of the pattern is slightly weakened accordingly.

  After the display plate 255 is fitted to the frame 262, the display plate 255 is fixed to the frame 262 with screws or the like, so that the display plate 255 is attached to the frame 262. That is, the display plate 255 can be easily detached from the frame 262. Here, the frame 262 is formed with ridges 266a, 266b for attaching the decoration display device 250 to the gaming machine 1 with screws or the like on the rear surface side of the side frames 264a, 264b, and as shown in FIG. When the decorative display device 250 is attached to the gaming machine 1, the display plate 255 projects from the surface of the glass door frame 17.

  In the decorative display device 250 attached to the gaming machine 1 in this manner, the light emitted from the LED propagates through the display plate 255 and is emitted from the lower end 156 side of the display plate 255. Accordingly, as shown in FIG. 19, the decorative display device 250 emits light not only at the pattern (light emitting portion) 60 but also at the lower end portion 156 of the display plate 255 when attached to the gaming machine 1. Can be used to obtain a high decorative effect. Further, since the portion protruding from the gaming machine 1 is almost only the thickness of the display plate 255, there is little possibility of colliding with something and causing damage or failure. FIG. 19 schematically shows how the lower end portion 156 of the decorative display device 250 attached to the glass door frame 17 emits light.

  In this example, the transmitted light 233 is emitted from the lower end 156 of the display plate 255, but conversely, the base frame 263 is provided on the lower side so that light is emitted from the lower end 156 of the display plate 255. The transmitted light 233 may be emitted from the upper end 154 of the display plate 255.

However, in this case, it is preferable to provide a shielding plate that prevents light emitted from the light source arranged for each display plate 55 from entering the other display plate 55. With such a configuration, the pattern 60 can be three-dimensionally lit and displayed, and by further individually controlling the light sources arranged with respect to the respective display plates 55, a luminescent display with more excellent production effects can be achieved. realizable.

  Further, the number, size, and arrangement of the notches 68 provided in the back plate 65 are not limited to those illustrated in the embodiment. Further, in the decorative display device 50 shown in FIG. 7, the lower end 54 of the display plate 55 is inserted into the inside of the base guide piece 63 by several centimeters so that the base guide piece 63 functions as a blindfold member that hides the streak of light. However, what range should be blinded may be set appropriately. It may be several millimeters. Moreover, you may comprise so that a player may intentionally show a light streak as a decoration effect. In addition, you may make it attach a separate blindfold member to a receiving part or a display plate instead of giving a blinding function to a receiving part itself.

  Further, instead of the reflective layer 74, a paint that diffuses the same light as the pattern (printing unit) 60 may be printed on the entire surface of the LED mounting substrate 72. In this way, the surface of the LED mounting substrate 72 is surface-emitted by the light emitted behind the light emitting diode, the amount of light incident on the display plate is increased, the light intensity of the pattern (printing portion) 60 is increased, and the light Uniform light emission without any streaks becomes possible.

  In addition, the decorative display device may be configured such that the lighting mode automatically changes after a predetermined time has elapsed. For example, the lighting color is changed in the morning, noon, and night to a color that matches it.

  The LED 71 may be a full color LED, and is not limited to a lamp type, and may be a surface mount type chip LED.

  In the other embodiments, the light from the light source is irradiated only from one end face of the display plate. However, the light may be irradiated from two or more end faces. For example, when the display plate is long in the vertical direction and it is difficult for the light to reach the other end only by irradiating light from one end surface, the light may be irradiated from both opposite end surfaces.

  Further, a translucent colored (for example, black) sheet or plate may be provided on the surface of the display plate. In this way, when the LED 71 is not lit, the pattern 60 is difficult to see. On the other hand, when the LED 71 is lit, an effect such that the pattern 60 appears from where there is nothing is possible, and the effect is improved.

  In the embodiment, the pattern 60 for diffusing light is formed by printing, but the pattern may be formed directly on the light guide plate by etching or engraving. The carved part diffuses the light in the light guide plate and emits light.
