Description

  The present invention relates to a display device provided on an island platform on which a gaming machine such as a pachinko machine or a slot machine is installed, and more particularly to a display device for the purpose of a decoration effect and a production effect.

  A gaming machine such as a pachinko machine or a slot machine installed in a game hall is usually accommodated on an island platform so that a plurality of gaming machines are arranged in a horizontal row at a height suitable for gaming. In addition, Shimadai accommodates a game medium lending device that lends game media such as pachinko balls and a counter that counts the game media acquired by the player.

  In addition, a collection supply device is built in the left and right center of the island stand to collect game media discharged from the gaming machine and the counter, polish and clean them, and supply them again to the gaming machine and the game media lending device. A replenishment rod for supplying game media from the collection and supply device to each gaming machine extends from the center of the island to both ends above the gaming machine, and is discharged from each gaming machine to the lower part of the gaming machine. A collection basket is collected from both ends of the island toward the center to collect the game media.

  The upper part of the island platform is covered with curtains and balustrades, and the lower part of the island platform is covered with waistboards and skirting boards so that such collection and supply devices, supply baskets, and collection baskets are not exposed. In addition, the left and right ends of the island stand are closed with tsum boards. Because the bamma and the twill boards are easily visible to the players, they can be used not only to prevent the internal structure from being exposed, but also to decorate the islands themselves. In particular, in order to enhance the decoration effect, there is an island stand that illuminates the space between the fields on which the symbols and characters are drawn, and allows the characters and symbols themselves to shine.

  For example, there is an island platform in which a light source is attached below the curtain plate and a space between characters and patterns (hereinafter referred to as plates) is indirectly illuminated (see, for example, Patent Document 1). In addition, there is a type in which a light source is arranged inside a translucent plate on which characters and patterns are drawn so that the plate emits light in a backlight manner (see, for example, Patent Document 2).

  Further, there is a type in which a light source is provided directly on the surface of a plate so that a pattern or a character itself emits light (see, for example, Patent Document 3 and Patent Document 4). Further, there is disclosed an island base in which an EL panel is formed by providing an EL (electroluminescence) element on the surface of a plate so as to emit a predetermined character, pattern or the like (for example, see Patent Document 5 and Patent Document 6). .)

  Indirect lighting of the plate, the plate itself does not emit light, so the decoration effect is not enough, and it will have an impact. In the case of illuminating the plate with a backlight or in which the light source is directly attached to the surface of the blade, although the plate itself shines, the plate becomes expensive and increases in thickness and requires attention to handling. In particular, since it is necessary to provide a space between the rails for opening and closing for maintenance and inspection such as a replenishing rod, a plate that is light and easy to handle without being bulky is preferable.

  In addition, when the light source is directly attached to the plate, it is essential to connect the control line and power line for lighting control to the light source inside the plate. Each time it is removed for reasons such as the control line, the connection of the control line and the power source is disconnected, and the troublesome work of connecting again later has occurred.

  Furthermore, in the case of using an EL (electroluminescence) element, since the emission intensity is weak, there is a problem that it is not conspicuous and unsuitable in a bright hall, and a lighting control device such as an inverter is required, which makes the device expensive. .

The pachinko island stand 1 shown in FIG. 1 is a double-sided island 1a in which a pachinko machine 2 is accommodated on both sides. In addition, Pachinko Island stand has a wall island that houses gaming machines only on one side.

  A curtain plate 7 spans the upper part of the pachinko island platform 1 (above the pachinko machine 2), and a display device 8 is provided as a space between them. A call lamp 9 is attached to the curtain plate 7 for each pachinko machine 2. The display device 8 is provided in units of a set of the pachinko machine 2 and the inter-stand unit 3, and the horizontal width of the display device 8 is one pachinko machine 2 and one stand arranged side by side. It is the width that combines the unit 3 between.

  Below the pachinko machine 2, a counter 4 for placing a ball box or the like is provided so as to protrude forward. A waist plate 5 is provided below the counter 4, and a baseboard 6 is provided between the lower side and the floor surface. In addition, the end plates 11 are attached to the left and right ends of the pachinko island stand 1. The end plate 11 is provided with a child integrated switch panel 21 (operation unit) for setting a lighting pattern of the display device 8 and the like.

  FIG. 2 is an exploded perspective view of the display device 8 attached to the pachinko island platform 1 as a balustrade. The display device 8 includes a frame 12 and a display plate 25, and the display plate 25 can be easily detached from the frame 12. The wire harness 17 coming out from the back surface of the frame 12 is a cable for electrically connecting a later-described LED board built in the frame 12 and a later-described individual control board installed on the pachinko island base 1. is there. The display device 8 is attached to an island pillar (not shown) of the pachinko island base 1 by a hinge 13a as a rotation shaft provided at both the upper left and right ends of the frame 12.

  FIG. 3 is a six-sided view showing the frame 12. (A) is a front view, (B) is a rear view, (C) is a right side view, (D) is a plan view, (E) is a bottom view, and (F) is an AA cross section of (A). FIG. As shown in FIGS. 2 and 3, the frame 12 includes a base frame 13, left and right side frames 14 a and 14 b, and a back plate 15. The base frame 13 and the side frames 14a and 14b form a U-shaped frame as a whole. In FIG. 3, the hinge 13a is not shown.

  The frame 12 is fitted from above the display plate 25 along the guide grooves of the left and right side frames 14a and 14b with the U-shaped open portion facing downward. Thereafter, the frame 12 and the display plate 25 are integrally fixed with screws (not shown) through screw holes 16a and 16b provided in the side frames 14a and 14b.

  The notch 18 formed in the upper part of the back plate 15 shown in FIG. 3B is provided for the role of a heat sink and the role of allowing the wire harness 17 to pass through. Further, as shown in FIG. 3E, stopper pieces 47a and 47b are provided inside the left and right ends of the base frame 13. As shown in FIG. The stopper pieces 47a and 47b maintain an appropriate clearance between the upper end surface 24 of the display plate 25 and the LED 71 provided inside the base frame 13 when the display plate 25 is mounted on the frame 12 (including contact prevention). ) Is formed for this purpose. The back plate 15 may be colored with a desired color.

  FIG. 4 is a hexahedral view showing the LED unit 76 as a light source unit housed in the base frame 13 of the frame 12. In FIGS. 4 and 6, the rear view is the same as the front view and is omitted. The LED unit 76 shown in FIG. 4 is configured by attaching the LED substrate 70 of FIG. 5 to the support plate 55 of FIG.

  As shown in FIG. 5, on the LED substrate 70, a set of three red LEDs 71a, blue LEDs 71b, and green LEDs 71c are arranged side by side in a set of five. The red LED 71a is 5φ (diameter 5 mm), and the blue LED 71b and green LED 71c are 3φ (diameter 3 mm). Since red has a lower emission intensity than blue and green, the difference in emission intensity is compensated for by using a 5φ red LED 71a.

  The LED substrate 70 has a structure in which two LED mounting substrates 72 and a base substrate 73 having the same size are stacked. The LED mounting substrate 72 and the base substrate 73 are formed with a width (7 to 10 mm) × a length (100 to 200 mm). Female connectors 75 a and 75 b are provided on both left and right ends of the back surface of the base substrate 73.

  As shown in FIG. 7, the red LED 71a used in the present embodiment has a thicker pedestal than the head, and the blue LED 71b is in the shape of a cylinder. The LED mounting board 72 has a hole having a size that allows the head of the red LED 71a to pass therethrough and cannot pass through the pedestal at a position corresponding to the mounting position of the red LED 71a. In addition, a through hole having a size through which the terminals of the LEDs 71b and 71c pass but cannot pass through the main body is formed at a position corresponding to the attachment location of the blue LED 71b and the green LED 71c. The base substrate 73 has through holes through which the terminals of the LEDs 71a and 71b pass, and a wiring pattern is provided on the back surface 73a.

  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) 25. Generally, if the length of the display plate 25 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 25 is long (for example, 40 cm or more), in order to ensure an appropriate amount of light at the other end, for example, a viewing angle of about 20 to 35 degrees and a high luminance type is used. 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 25 can be maintained while reducing the cost as much as possible.

  As shown in FIG. 6, the support plate 55 includes a fitting convex portion 56 at one end in the length direction and a fitting concave portion 57 at the other end, and is fitted with the fitting convex portion 56 of the adjacent support plate 55. A plurality of support plates 55 can be connected in a row by fitting the recess 57. Cutouts 58a and 58b are provided at positions corresponding to the female connectors 75a and 75b of the LED board 70 inserted into the support plate 55. The storage walls 59a and 59b provided in the lower part store the male connector 78, the male connector 19, the harness 77, and the harness 17 that are fitted to the female connectors 75a and 75b of the base board 73, as shown in FIGS. Fulfills the function of

  FIG. 8 shows how the LED units 76 are connected to each other. After the fitting convex portion 56 and the fitting concave portion 57 are fitted and connected, the adjacent LED units 76 are electrically connected with a harness 77 having male connectors 78 at both ends. Furthermore, the male connector 19 of the wire harness 17 for electrically connecting to the individual control board is connected to the female connector of the LED unit 76 located at either end.

  FIG. 9 is a front view of a state in which two LED units 76 are connected, and FIG. 10 is a bottom view of a state in which two LED units 76 are connected. The male connectors 78 and 19 and the surplus harness 77 are accommodated inside the storage walls 59a and 59b.

  FIG. 11 is a bottom view showing a state in which the LED unit 76 is installed in the base frame 13, and FIG. 12 is a front view showing a part of the state in which the LED unit 76 is installed in the base frame 13. FIG. 12 shows a state in which the front plate (portion indicated by a broken line) of the base frame 13 is removed.

  As a means for installing the LED unit 76 on the base frame 13, screwing, adhesion, fitting, or the like can be considered.

  Since the male connector 78, the male connector 19, and the surplus harness 77 are accommodated inside the housing walls 59a and 59b, the LED unit 76 is closely attached to the back wall of the base frame 13 without the surplus harness 77 and the like getting in the way. It is possible to insert it securely until it is done. Further, heat when the LED unit 76 is turned on is released to the outside from the notch 18 formed in the back plate 15. Further, in the drawing, the cutout 18 at the right end is a passage opening for the wire harness 17.

  FIG. 13 is a front view showing the display device 8 with the display plate 25 attached to the base frame 13 together with its internal structure. Since the upper end 24 of the display plate 25 abuts against the stopper pieces 47a and 47b, a slight clearance is secured between each LED 71 of the LED unit 76 and the upper end of the display plate 25.

  As shown in FIG. 2, the display device 8 is attached to the pachinko island base 1 so as to be rotatable by an upper hinge 13a, and the LED unit 76 is built in the rotation shaft side of the display device 8 as shown in FIG. For this reason, even if the display device 8 is opened and closed around the hinge 13a, the position of the LED unit 76 is not displaced so much, the wire harness 17 can be shortened, and wiring and the like are facilitated.

  FIG. 14 is an exploded perspective view of the display plate 25, the reflective tape 26, and the reflective sheet 28. A reflective tape 26 is attached to the peripheral edge of the display plate 25, and a reflective sheet 28 is attached to the back side of the display plate 25. The reflective tape 26 is not formed on the end 24 of the display plate 25 where the LED 71 faces.

  The reflection sheet 28 may be a sheet colored in white or glossy color. Further, the reflection sheet 28 may be provided only in the portion overlapping the pattern (printing unit) 30 and a desired background color may be applied to other portions. That is, the reflection sheet 28 only needs to be at least in a portion overlapping the character portion 30 in order to improve the light emission intensity of the pattern (printing portion) 30.

  The reflective tape 26 may be a tape colored white or glossy like the reflective sheet 28. As a result, the light passing through the inside of the display plate 25 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) 30 is improved.

  The display plate 25 as a light guide plate is formed with a thickness of about 5 mm, and a printing part (fish picture) 30 as a pattern (light emitting part) for diffusing light is provided on the back side (reflection sheet 28 side). 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 Al ₂ O ₃ , TiO ₂ , and SiO ₂ , sulfate particles such as BaSO ₄ , and carbonates such as CaCO ₃ Examples thereof include inorganic compound particles such as particles, glass fine powder and glass balloon, and micro air cells. 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. In addition, the coating material can use thermosetting resins, such as an acrylic resin, a urethane resin, and an epoxy resin, or what uses adhesives, such as an acrylic type, a rubber type, and an elastomer type, as a binder.

  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 25. 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.

  Further, as the material of the light guide plate constituting the display plate 25, a transparent material having a high refractive index is used, and methacrylic resin (PMMA), acrylic resin, etc. are preferable. 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 Acrylic rubber, a transparent material such as silicone rubber is.

  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 25 can form the light emitting portion 30 which is a pattern for diffusing light by printing, so that 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 edge part 24 of the display plate 25 which LED71 faces. This is because the printing unit 30 does not emit light neatly due to the directivity of the LED 71 if printing is performed too close to this end face.

  FIG. 15 shows the relationship between the directivity of the LED 71 and the irradiation area. When attention is paid to the red LED 71a, no light directly reaches the portion indicated by the hatched portion 301 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 301 where direct light does not reach within the base frame 13 so as to cover the streaks of light with the base frame 13. In the display device 8 shown in FIG. 13, the upper end 24 of the display plate 25 enters several centimeters inside the base frame 13, and the base frame 13 functions as a blindfold member that hides light streaks.

  Further, as shown in FIG. 16, even when the range 301 where the direct light from the LED 71 does not reach all fits in the base frame 13, the pattern 302 may be printed while avoiding the range 301. Therefore, the pitch and directivity (viewing angle) of the LEDs 71, the width of the base frame 13, and the like may be designed in consideration of 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 25 may be other than 5 mm, and may be in a range of approximately 3 to 7 mm. If it is less than this range (less than 3 mm), the light emission intensity decreases. On the other hand, if this range is exceeded (exceeds 7 mm), there is no problem with the light emission intensity, but the display plate 25 becomes thicker. It is unpreferable in handling because it is bulky or heavy.

  FIG. 17 shows a propagation path of light incident from the LED 71 inside the display plate 25, and FIG. 18 shows how the light incident from the LED 71 is reflected by the printing unit 30. For example, the light emitted from the LED 71 passes through the inside of the display plate 25 as indicated by the incident light 31, and the incident light 31 that has reached the edge of the display plate 25 is reflected by the reflective tape 26 and again displayed on the display plate 25. 25 passes through. Then, when the incident light 31 reaches the printing unit 30 in the process of following such a path, a diffused reflected light 32 as shown in FIG. 18 is generated due to the diffuse reflection characteristic, and this light is transmitted to the outside of the display plate 25. The printed part 30 appears to emit light. Note that the end surface 24 of the display plate 25 facing the LED 71 is preferably subjected to buffing (polishing ... mirror surface processing), which further increases the light emission intensity of the pattern (printing portion) 30.

  FIG. 19 schematically shows how the pattern (printing unit 30) of the display device 8 emits light. Since the entire display plate 25 does not shine but only the pattern (printing portion 30) on the display plate 25 shines, a high decorative effect can be obtained.

  By the way, the emission color of the pattern (printing unit) 30 is determined by the printing color of the printing unit 30 and the emission color (wavelength) of the LED 71. That is, if the printing color of the printing unit 30 is colorless or white, the emission color of the LED 71 is almost the emission color of the pattern (printing unit 30). If the printing color of the printing unit 30 is colored, a color obtained by mixing substantially the printing color of the printing unit 30 and the emission color of the LED 71 becomes the emission color of the pattern (printing unit 30). If the emission color of the LED 71 is white, the printing color of the printing unit 30 is almost the emission color of the pattern (printing unit 30).

  FIG. 20 is an explanatory diagram illustrating the relationship between the combination of the LED emission color (wavelength) and the pattern (printing portion) printing color and the light emission intensity of the printing portion. 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) 30 depends on both the emission color (wavelength) of the LED 71 and the printing color of the printing unit 30. When the printing color of the printing unit 30 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 30) emits little light. Further, when the emission color of the LED 71 and the printing color of the printing unit 30 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 30 approach the complementary color relationship.

  For example, when the LED color is “red” and the print color is “green” or “blue”, the emission intensity is somewhat weak “C” because of the complementary color relationship or the relationship close to the complementary color. In addition, when the LED color is “blue” and the print color is its complementary color “red”, the light emission intensity becomes “D” which is very weak. Therefore, if a blue pattern and a red pattern are printed on the display plate 25 and the color of the LED to be lit is switched between blue and red, only the red pattern is emitted 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.

  FIG. 21 is an example of a schematic plan view of a pachinko hall. In the figure, wall islands 1b are provided along the left and right wall surfaces, and a double-sided island 1a is provided at the center of these. There are a parent island and a child island in the gaming machine island, a parent integrated control board 80 is attached to the parent island (the left wall island 1b in the figure), and a child integrated control board 90 is attached to the child island. . These are circuits for controlling the lighting pattern of the display device 8. The parent integrated control board 80 and the child integrated control board 90 installed on each island are connected to each other by a harness 88 that straddles the passage 22. This connection is made through the floor or the ceiling.

  A large number of individual control boards 60 are cascade-connected to the parent integrated control board 80 and the child integrated control board 90 of each island through a cable spanned inside the island. In the case shown in FIG. 21, the individual control boards 60 are installed at a ratio of one to two pachinko machines. The LED unit 76 of the display device 8 is connected to each individual control board 60 through the wire harness 17. In addition, a call lamp 9 provided in association with each pachinko machine 2 is also connected.

  FIG. 22 is a block diagram showing a circuit configuration of the child integrated control board 90, and FIG. 23 is a front view of the child integrated switch panel 21.

  The child integrated control board 90 has a CPU (Central Processing Unit) 91 for overall control of the operation of the apparatus, and a ROM (Read Only Memory) 96 and a RAM (Random Access Memory) are provided on the bus 94. ) 97, an input circuit 92, and an output circuit 93 are connected. The input circuit 92 includes a parent integrated control board 80, a jackpot lighting pattern setting switch 35 disposed on the child integrated switch panel 21, a lighting color setting switch 36, a normal lighting pattern setting switch 37, and a grouping setting switch 38. Is connected. The output circuit 93 is connected to the individual control board 60 of the own island and the 7-segment display 34 arranged on the child integrated switch panel 21.

  Each of the switches 35 to 38 of the child integrated switch panel 21 is a push type, and the display of the 7-segment display 34 changes in order from “1” to “6” each time it is pressed once.

  The big hit lighting pattern setting switch 35 is a switch for setting a big hit (may be a probability change or a short time) lighting pattern in one of the six predetermined intervals in the self-island space (display device) 8. The lighting color setting switch 36 is a switch for setting the lighting color in the space between the own islands (display device) 8 to any one of the six types. The normal lighting pattern setting switch 37 is a switch that can set the lighting pattern at normal time (other than big hit, probability change, and short time) from any of six patterns.

  The grouping setting switch 38 is a switch for setting the group number of this island managed by the child integrated control board 90. The 7-segment display 34 indicates the selected group number, and islands set to the same number are grouped into the same group.

  FIG. 24 is a block diagram showing a circuit configuration of the parent integrated control board 80, and FIG. 25 is a front view of the parent integrated switch panel 20. The master integrated control board 80 functions as a slave unit for the self-island in addition to a function as a master unit for controlling the slave unit (slave integrated control board 90).

  The parent integrated control board 80 has a CPU 81 for overall control of the operation of the apparatus, and a ROM 86, a RAM 87, an input circuit 82, and an output circuit 83 are connected to the bus 84 thereof. The input circuit 82 includes a jackpot lighting pattern setting switch 35, a lighting color setting switch 36, a normal lighting pattern setting switch 37, a grouping setting switch 38, and a grouping designation switch 39 disposed on the parent integrated switch panel 20. A grouping lighting on / off switch 40 and a grouping lighting pattern setting switch 41 are connected. Further, the child integrated control board 90 of the other island, the individual control board 60 of the own island, and the 7-segment display 34 disposed on the parent integrated switch panel 20 are connected to the output circuit 83.

  Each of the switches 35 to 39 of the parent integrated switch panel 20 is a push type, and the display of the 7-segment display 34 changes in order from “1” to “6” each time it is pressed.

  The big hit lighting pattern setting switch 35, the lighting color setting switch 36, the normal lighting pattern setting switch 37, and the grouping setting switch 38 are the same as the child integrated control board 90. The grouping designation switch 39, the grouping lighting on / off switch 40, and the grouping lighting pattern setting switch 41 are switches provided only on the parent integrated control board 80. Using these, it is possible to forcibly light a specific lighting pattern (grouping lighting) on the display devices 8 of a plurality of islands belonging to a specific group.

  The grouping designation switch 39 is a switch for designating a group number to be turned on (activated). When the grouping lighting on / off switch 40 is turned on, the setting of the switches 35, 36, and 37 on each island is invalidated, and grouping lighting is executed on the island having the group number designated by the grouping designation switch 39. The lighting pattern used for grouping lighting and the lighting color of the LED are selected by a grouping lighting pattern setting switch 41 from a plurality of predetermined types (here, A, B, C).

  Examples of usage of grouping lighting include service time for each island (model), notification of a ladies' corner, and the like.

  The parent integrated control board 80 outputs a synchronization signal to the child integrated control board 90, and each island turns on, blinks, fades in, fades out (hereinafter referred to as gradation), or turns off at the same timing. ing. Furthermore, the parent integrated control board 80 also outputs a synchronization signal to the individual control board 60 on its own island, and the space (display device) 8 corresponding to each pachinko machine 2 lights up at the same timing as above. It is like that.

  FIG. 26 is a block diagram showing a circuit configuration of the individual control board 60. The individual control board 60 has a CPU 61 for overall control of the operation of the apparatus, and a ROM 66, a RAM 67, an input circuit 62, and an output circuit 63 are connected to the bus 64 thereof. The input circuit 62 is connected to the parent integrated control board 80 and the child integrated control board 90 that are installed on the island. The input circuit 62 is connected to the individual control board 60 adjacent to the same island and the calling lamp 9. The output circuit 93 is connected to the individual control board 60 adjacent to the same island and the LED unit 76.

  A big hit (probability change or short time) signal is inputted from the calling lamp 9, and when this big hit signal is inputted, the individual control board 60 executes the big hit lighting pattern instead of the normal lighting pattern. When a big hit signal (or running signal) is input, a running lighting process is executed and a running signal is output to the adjacent individual control board 60. The running lighting process refers to lighting control in which a plurality of display devices 8 installed on an island platform are operated in a coordinated manner to move a lighting location so that light runs from one end of the island to the other.

  FIG. 27 is a lighting pattern list showing the relationship between the numbers displayed on the 7-segment display corresponding to the switches 35 to 39, the lighting pattern or lighting color of the space (display device) 8, and the lighting color during running. 310 is shown. Each of the six patterns that can be selected by the big hit lighting pattern setting switch 35 is a combination of the initial high-speed flashing and the subsequent low-speed flashing, and the flashing periods have different lengths.

  The lighting color during normal lighting can be selected from six colors of red, blue, green, orange, purple and light blue. Orange is colored by simultaneous lighting of red LED 71a and green LED 71c, purple is colored by simultaneous lighting of red LED 71a and blue LED 71b, and light blue is colored by simultaneous lighting of blue LED 71b and green LED 71c.

  When the lighting color setting switch 36 is operated, the lighting color at the time of running lighting is set simultaneously with the lighting color at the time of normal lighting. When the lighting color during normal lighting is red, the lighting color during running lighting is set to blue. Similarly, when the normal lighting color is blue, the running lighting color is green. When the normal lighting color is green, the running lighting color is red. When the normal lighting color is orange, the running lighting color is blue. When is purple, the running lighting color is set to green, and when the normal lighting color is light blue, the running lighting color is set to red.

  The running lighting process is performed while interrupting the normal lighting. Therefore, the running lighting color is set to the color of the LED that is normally used and not used. For example, when the lighting color setting switch 36 is set to orange ("4" is displayed on the 7-segment display 34), the running lighting color is blue. This is because orange is colored by the red LED and the green LED, so the color difference increases by making blue not used for orange coloring, and running lighting can be conspicuous. . For the same reason, when the color is purple, the running color is green, and when the color is light blue, the running color is red.

  In addition, in the lighting pattern or lighting color in the grouping lighting pattern setting switch 41, red and light blue, blue and orange, green and purple are alternately lit for the same reason. By making the difference in color conspicuous in this way, the decoration effect is enhanced.

  The gradation set by the normal lighting pattern setting switch 37 is a mode in which the color is gradually turned on or turned off. The types of lighting patterns or lighting colors are not limited to the 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.

  FIG. 28 shows the flow of control processing performed by the parent integrated control board 80. Immediately after the power is turned on, the CPU 81 initializes each flag, each register, and each storage area necessary for stack setting and the following processing in initialization processing (step S401). Next, if there is an input (operation) of each switch 35-39 (step S402; Y), a numerical value is displayed on the corresponding 7-segment display 34 (step S403), and the setting of each switch 35-38 at the present time. A basic lighting command and a grouping signal corresponding to the state are output to the individual control board 60 of the own island (step S404).

  After that, or when there is no input from each switch 35-39 (step S402; N), it is checked whether or not the grouping lighting on / off switch 40 is ON. If it is ON (step S405; Y), the child integrated control board 90 outputs a grouping signal and a group lighting command corresponding to the setting states of the grouping designation switch 39 and the grouping lighting pattern setting switch 41 (step S406).

  Thereafter, it is checked whether or not the own island is set to the group designated by the grouping designation switch 39. When the own island belongs to the group designated by the grouping designation switch 39 (step S407; Y), individual control of the own island is performed. A group lighting command corresponding to the input of the grouping lighting pattern setting switch 41 is output to the substrate 60 (step S408), and the process is terminated. The determination in step S407 is made based on whether or not the setting of the grouping setting switch 38 and the designation of the grouping designation switch 39 are the same.

  When the grouping lighting on / off switch 40 is OFF (step S405; N) and when the self-island does not belong to the group designated by the grouping designation switch 39 (step S407), this processing is terminated at that point (end). ). This process is repeatedly executed at a predetermined cycle (several milliseconds) except for the initialization process in step S401.

  FIG. 29 shows the flow of control processing performed by the child integrated control board 90. Immediately after the power is turned on, the CPU 91 initializes each flag, each register, and each storage area necessary for stack setting and the following processing in initialization processing (step S421). Next, if there is an input from each switch 35-38 (step S422; Y), a numerical value is displayed on the corresponding 7-segment display 34 (step S423), corresponding to the current setting state of each switch 35-38. The basic lighting command and the grouping signal to be output are output to the individual control board 60 of the own island (step S424).

  After that, or when there is no input to each of the switches 35 to 38 (step S422; N), it is checked whether or not a group signal and a group lighting command are input from the parent integrated control board 80. If there is an input (step S425; Y) It is checked whether or not the own island belongs to the group indicated by the group signal. If it belongs (step S426; Y), it corresponds to the input of the grouping lighting pattern setting switch 41 on the individual control board 60 of the own island. A group lighting command is output (step S427), and the process is terminated.

  When no group signal or group lighting command is input (step S425; N) or when the own island does not belong to the group indicated by the input group signal (step S426; N), this processing is terminated at that point ( End). This process is repeatedly executed at a predetermined cycle (several milliseconds) except for the initialization process in step S421.

  FIG. 30 shows the flow of control processing performed by the individual control board 60. The individual control board 60 first performs initialization processing (step S441), and thereafter performs basic lighting processing (step S442), group lighting processing (step S443), and running lighting processing (step S444) in a predetermined cycle. Repeatedly (several milliseconds).

  The lighting pattern has a priority, and is in order of running lighting, group lighting, jackpot lighting, and normal lighting from the highest.

  FIG. 31 shows the flow of basic lighting processing performed by the individual control board 60. When an input such as a basic lighting command or a grouping signal corresponding to the input (operation) of each switch 35 to 38 is received from the child integrated control board 90 or the parent integrated control board 80 (step S461; Y), the input signal Accordingly, the setting in the own apparatus relating to the lighting pattern or the like is changed (step S462).

  After that or when there is no input of the above signal (step S461; N), it is checked whether the group lighting process or the running lighting process is being processed. If any of them is being processed (step S463; Y or step S464; Y ) At this point, this process is terminated (END). Whether or not the group lighting process is in progress is recognized by referring to a flag that is set / reset in the group lighting process. Similarly, whether or not the running lighting process is in progress is recognized by referring to a flag that the running lighting process is set / reset.

  When the group lighting process or the running lighting process is not being performed (step S464; N), it is checked whether a jackpot signal is input from the calling lamp 9, and if a jackpot signal is input (step S465; Y), the jackpot is lit. The lighting control by the pattern is executed (step S466), and this process is ended (END). When the big hit signal is not inputted (step S465; N), the lighting control by the normal lighting pattern is executed (step S467), and this processing is ended (end).

  FIG. 32 shows the flow of the group lighting process performed by the individual control board 60. It is checked whether or not a group lighting command is input from the child integrated control board 90 or the parent integrated control board 80. If there is no input (step S481; N), this process is ended (END). When a group lighting command is input (step S481; Y), the setting is changed accordingly (step S482).

  Thereafter, it is checked whether or not the running lighting process is being performed. If the process is being performed (step S483; Y), the present process is terminated at that time (end). If the running lighting process is not being performed (step S483; N), Lighting control based on the group lighting pattern is executed (step S484), and this process is ended (END).

  FIG. 33 shows the flow of the running lighting process performed by the individual control board 60. When the jackpot signal is input from the calling lamp 9 or the running signal is input from the adjacent individual control board 60 (step S501; Y), the lighting control by the running lighting pattern is executed (step S502). A running signal is output to the individual control board 60 adjacent to the direction opposite to the input direction (step S503). For the individual control board 60 located at the end in the island, the running signal is returned to the same individual control board 60 to which the running signal is input. Thereby, a lighting location moves so that an end may be reciprocated from the end of an island.

  When neither a big hit signal nor a running signal is input (step S501; N), this processing is ended as it is (end).

  The lighting control is as follows. In the normal state, each display device 8 in the island is lit in the normal lighting pattern. For example, gradation lighting with a period of 8 seconds is performed. At this time, if a big hit occurs in any of the pachinko machines 2, lighting control is performed with the big hit lighting pattern in the display device 8 (installed above) corresponding to the pachinko machine 2. At the same time, the running lighting starts, and the display device 8 corresponding to the pachinko machine other than the pachinko machine in which the jackpot is generated interrupts the lighting control by the normal lighting pattern only when the running signal comes from the adjacent individual control board 60. For a moment, running lights (change colors) are performed. In the pachinko machine 2 in which the big hit has occurred, only when the running signal arrives from the adjacent individual control board 60, the lighting control by the big hit lighting pattern is interrupted and the running lighting (changing the color) is performed for a moment.

  FIG. 34 is a perspective view showing another example of the display plate 25. Up to now, a pattern having the property of diffusing light is formed directly on the display plate 25 by printing, but in this example, the film sheet 48 on which the pattern (light emitting portion) 30 that diffuses light is printed is used as the display plate (light guide plate). ) It is configured to stick to 25. The film sheet 48 is a film-like sheet cut into the same shape as the display plate 25.

  In this case, the pattern (light emitting part) 30 may be printed on the back side of the film sheet 48 (on the side opposite to the surface attached to the display plate 25). The reason for this is that the display plate 25 and the film sheet 48 can be adhered and adhered so that there is no gap, thereby increasing the light emission intensity of the pattern. When the pattern is provided on the back side, a colored transparent or colorless transparent film sheet 48 is used. When the pattern is provided on the surface side, the film sheet 48 may be opaque, or the film sheet 48 itself may have a function of producing a background color or a function as a reflector.

  FIG. 35 is a perspective view showing still another example of the display plate 25. Here, the cutting sheet 49 obtained by cutting the film sheet on which the pattern (light emitting unit) 30 is printed into the shape of the pattern is adhered to the display plate 25.

  If the film sheet on which the pattern is printed as shown in FIGS. 34 and 35 is attached to the display plate 25, the design of the space 8 is simply peeled off or pasted from the sheet (cutting sheet or film-like sheet). This makes it possible to make changes very easily, leading to cost reduction when changing the design. In particular, in the cutting sheet 49, various designs can be formed by changing the combination method of the plurality of cutting sheets 49 and the arrangement when pasting on the display plate 25.

  Even when the pattern is directly printed on the display plate 25, the plate material (light guide plate) can be recycled by deleting the original printing and printing a pattern with a new design.

  FIG. 36 is a perspective view showing another example of the pachinko island stand 1. The display device can be applied to other than the space 8, and can be applied to, for example, the inter-unit 3, the counter 4, the waist board 5, the baseboard 6, the curtain board 7, and the end panel (island decoration) 11 (in the figure, hatched lines are shown) Place) Moreover, you may apply not only to the pachinko island stand 1 but the island which installs game machines other than a pachinko machine, such as a slot island and an arrangement island.

  FIG. 37 shows an example in which the display device according to the present invention is applied to the counter 4 and the waist plate 5. In this example, an integrated top and bottom plate 145 in which a counter and a waist plate are integrally formed in a substantially L shape is formed, and this integrated top and bottom plate 145 is used as a display device. The printing surface of the display plate 125 (the surface having a pattern for diffusing light) is the lower side in the figure in the counter unit 125a and the back side in the figure in the waist plate unit 125b. Therefore, when the display plate 125 is manufactured, first, printing is performed on both sides of the flat light guide plate (printing for the counter unit 125a and printing for the waist plate unit 125b), and then bending into a substantially L shape. do it.

  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 and surface hardness to the cast plate, and the counter portion 125a and the waist plate portion 125b are also places where the player can easily touch (in some cases, cigarette fire or kicking) Etc.) Here, in consideration of these, a tempered glass 146 that protects the counter portion 125a and a scratch-proof coating 147 that protects the waist plate portion 125b are provided. What is necessary is just to attach the tempered glass 146 so that the upper surface of the counter part 125a may be covered by an appropriate means. Further, a photocatalyst (titanium oxide) may be mixed in the scratch-proof coating 147.

  The LED unit 76 is attached to the frame 112 in the same manner as the frame 12 shown in FIGS. 11 and 12 and is configured to irradiate light from the lower end side of the display plate 125. Thereby, the light emitted from the LED propagates along the L-shaped shape through the inside of the display plate 125, reaches the end surface (the reflective tape 26) of the counter unit 125a, and is further reflected and repeatedly propagated inside. . As described above, the display device according to the present invention can be used not only on a flat surface but also on a curved surface, so that it is very convenient to use. Further, the counter unit 125a and the waist plate portion 125b can share the LED unit 76, which reduces the number of necessary light sources and reduces the cost.

  FIG. 38 shows an example in which the display plate 125 shown in FIG. 37 is provided with a protective plate 151 for protecting the end surfaces of the counter portion 125a and the tempered glass 146. The protection plate 151 is configured by a metal plate or the like having a size that just covers both the end surface of the counter portion 125 a and the end surface of the tempered glass 146 on the player side end surface of the counter 4. As long as the boundary portion between the counter portion 125a and the tempered glass 146 can be covered, the width may be narrower than that illustrated, but it is desirable to cover the entire end portion. As another example of this protection means, both the end face of the tempered glass 146 and the overlapping side of the end face of the counter portion 125a may be chamfered and subjected to a caulking process.

  In recent years, in the hall, there have been frequent mischiefs that insert foreign objects such as prepaid cards into the slight gap between the pachinko machine and the inter-unit unit due to the losing player, and this has caused clogging and equipment in the island A failure has occurred.

  When the protective tempered glass 146 is stacked on the counter portion 125a, it is assumed that the same mischief as described above occurs. That is, as shown in FIG. 39, there is a possibility that a foreign substance 153 such as a prepaid card is inserted into the gap 152 between the overlapping surfaces of the counter portion 125a and the tempered glass 146. When a foreign object is inserted, the foreign object is placed on the light emitting pattern (design) and the pattern is covered, and the decorative effect of the design is significantly reduced. The protective plate 151 functions to prevent such mischief and protect the end surfaces of the tempered glass 146 and the display plate 125 (counter portion 125a).

  FIG. 40 shows an example in which the display device according to the present invention is applied to the waist plate 5. In this example, a flat waist plate 205 similar to the space 8 described with reference to FIG. 2 is used as a display device. Light is emitted from the upper end 224 side of the display plate 225, and the floor surface of the hole is transmitted by the transmitted light 233 emitted from the lower end 223 without attaching a reflective tape to the lower end 223 of the display plate 225. (Foot lighting).

  For this reason, buffing (polishing: mirror finishing) is applied not only to the upper end portion 224 side but also to the lower end portion 223 side, thereby increasing the transmitted light 233. However, the emission intensity of the pattern is slightly weakened accordingly. Further, the harness connecting the LED unit 76 and the individual control board 60 is divided into two parts, a male connector 19 extending on the individual control board 60 and a harness 217 connected to the frame 213 side housing the LED unit 76. The harnesses 19 and 217 are detachably connected by the male connector 19 and the female connector 275. Thereby, when carrying out maintenance / inspection or the like in the island, the female connector 275 can be removed from the male connector 19 and the waist plate 205 can be removed, so that workability is improved (especially slot island). Such a relay connector may be provided in the middle of the harness 17 connected to the display device 8 shown in FIG.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  In the embodiment, a U-shaped frame is shown as an example, but the shape of the frame is not limited to this. For example, it may be a frame that surrounds the four sides of the display plate or a frame that supports the display plate so as to be sandwiched between two opposing sides. Further, the L-shaped frame may be one that supports only one side of the display plate, for example, one that sandwiches and supports end portions of the plate from both front and back surfaces.

  Moreover, although the hinge was illustrated in embodiment as a rotating shaft for attaching a flame | frame to an island stand rotatably, other support methods may be sufficient if it can rotate. Further, it may be rotated within an angle range necessary for maintenance and inspection, for example, a rotation angle of about 90 to 120 degrees is sufficient. In addition, in the case of the space 8 or the like, the frame may be configured to be held at the open position. The holding can be performed using a stay, a hook, a hydraulic cylinder, or the like.

  Further, the number, size, and arrangement of the notches 18 provided in the frame are not limited to those illustrated in the embodiment. Further, in the display device 8 shown in FIG. 13, the upper end 24 of the display plate 25 enters the inside of the base frame 13 so that the base frame 13 functions as a blindfold member that hides the streak of light. What range may be set as appropriate to be blindfolded. It may be several millimeters. Moreover, you may comprise so that a player may intentionally show a light streak as a decoration effect. Instead of providing the frame itself with a blindfold function, a separate blindfold member may be attached to the frame or the display plate.

  In addition, the space (display device) 8 may be configured such that the lighting mode automatically changes when a predetermined time elapses. For example, the lighting color is changed in the morning, noon, and night to a color that matches it.

  In the embodiment, one display device 8 is provided for one pachinko machine 2, but two or more display devices 8 may be provided for one pachinko machine 2. For example, when a plurality of display devices 8 are provided separately in the space 8 and other places, the lighting modes such as alternating flashing and simultaneous flashing can be further increased.

  One individual control board 60 is provided for the two display devices 8, but may be four to one or six to one. The same applies when the display device is provided in a space other than the space 8.

  In the embodiment, the parent integrated switch panel 20 and the child integrated switch panel 21 are provided on the end plate 11. However, this is not limited, and may be provided, for example, on an island pillar inside the island at a position where the space 8 is opened. Further, it may be configured by a remote control device. The remote control device may be dedicated, but for example, the parent integrated control board 80 and the child integrated control board 90 may be connected to a hall management computer or the like through a network in a hall and remotely operated from here.

  You may provide multiple types of LED unit 76 (LED board | substrate 70) length so that it can respond | correspond to the width | variety (40-100 mm) of the unit between tables 3 which differ in each hole. By combining LED units having different lengths, the display unit as a whole can cope with a wider variety of widths.

  Although the LED unit 76 is provided on the frame 12 as a component, it may be provided directly on the pachinko island base 1 side. Further, the method of incorporating the light source into the frame 12 is not limited to the one exemplified in the embodiment. For example, the light source unit can be connected to a plurality of light source units, but may be configured to accommodate one light source unit corresponding to the width of the frame. Moreover, you may attach a light source directly to a flame | frame. That is, the LED substrate may be directly attached to the frame with a screw or the like.

  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.

  In the embodiment, the pattern 30 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.
