And a medal storage and discharge mechanism for temporarily storing medals and discharging medals in accordance with control signals from the control circuit.

  An opening 11 is formed at the center upper portion of the front surface of the main body housing 1, and the light emitting drums 2 a to 2 c are visible through the opening 11. A medal slot 13 for inserting medals is formed on the upper surface of the frame 12 below the opening 11. The light emitting drums 2a to 2c can be individually rotated around a rotation axis (not shown) that is substantially parallel and substantially horizontal to the front surface of the main body housing 1 in accordance with a control signal from the control circuit. It has become. The surfaces of the light emitting drums 2a to 2c are each divided into a plurality of regions having substantially the same width along the rotation direction, and various designs are drawn for each region. Instead of the light emitting drums 2 a to 2 c, a display device such as a liquid crystal display may be provided so that the display screen can be viewed through the opening 11. In this case, the display device displays on the display screen a display pattern that schematically shows a plurality of drums in accordance with a control signal from the control circuit. The start lever 3 is provided on the left side toward the front surface of the frame 12 of the main body housing 1. In addition, stop buttons 4 a to 4 c are provided in the approximate center of the front surface of the frame 12. The stop buttons 4a to 4c correspond to the light emitting drums 2a to 2c, respectively.

  A display device 5 according to one embodiment of the present invention is provided as a lower panel at the lower part of the front surface of the main body casing 1. Details of the display device 5 will be described later. Further, below the display device 5, the main body housing 1 is formed with a medal discharge port 14 for discharging medals. A medal tray 15 for preventing the discharged medals from dropping is attached below the medal discharge port 14.

  When the start lever 3 is operated after the medal is inserted into the medal insertion slot 13, a signal indicating that the start lever 3 has been operated is transmitted to the control circuit. Then, the control circuit starts the rotation of the light emitting drums 2a to 2c. Thereafter, when any one of the stop buttons 4a to 4c provided at the front center of the frame 12 of the main body casing 1 is pressed, the control circuit receives a signal indicating that the button is pressed from the pressed switch. Then, the rotation of the light emitting drum corresponding to the pressed switch is stopped. Or a control circuit stops the light emitting drum from which the corresponding stop switch was not pressed down after the predetermined period progresses after a predetermined period passes, after rotation starts among the light emitting drums 2a-2c. When all the light emitting drums are stopped and the same symbol is arranged in a line across all the light emitting drums, the control circuit discharges a predetermined number of medals corresponding to the symbol through the medal discharge port 14.

  2A is a schematic configuration diagram of the display device 5 according to the first embodiment of the present invention, and FIG. 2B is a partially exploded perspective view of the display device 5.

  The display device 5 includes a first display plate 51, a light guide plate 52, a first light source 53, a second display plate 54, a second light source 55, a control unit 56, and a housing 57. The first display board 51 is positioned in front of the observer so that the first display pattern provided on the first display board 51 and the second display pattern provided on the second display board 54 are visible to the observer. Placed in. The light guide plate 52 is arranged on the back side of the first display plate 51, the first light source 53 is arranged on the side surface of the light guide plate 52, the second display plate 54 is arranged on the back side of the light guide plate 52, and the second The light source 55 is disposed on the back side of the second display panel 54. The light from the first light source 53 enters the light guide plate 52, diffuses by propagating through the light guide plate 52, enters the first display plate 51, and is provided on the first display plate 51. Illuminate the display pattern. On the other hand, the light from the second light source 55 is transmitted through the transmissive area corresponding to the second display pattern provided on the second display plate 54 and the light guide plate 52, and is incident on the first display plate 51 to be the first. By irradiating the diffusion surface of the display board 51, an observer located in front of the first display board 51 can observe the second display pattern.

  FIG. 3 is a side view of the first display panel 51.

  The first display plate 51 is a flat member having a flat first substrate 511, a first display pattern forming layer 512, and a diffusion layer 513. The first substrate 511 is transparent to light, and is formed by molding a resin that is transparent to light, such as polymethyl methacrylate (PMMA), polycarbonate (PC), and cycloolefin polymer.

  The first display pattern forming layer 512 presents the first display pattern to an observer positioned in front of the first display plate 51 when the light from the first light source 53 illuminates the first display plate 51. For example, it is formed by color printing on the back surface of the first substrate 511 using a plurality of colors of ink. The ink used when forming the first display pattern forming layer 512 is, for example, a light transmissive pigment or dye. In addition, a part of the ink used when forming the first display pattern forming layer 512 may be a light-impermeable pigment or dye. In one example, the first display pattern forming layer is printed by printing each of the first formation region 5121 to the third formation region 5123 shown in FIG. 2B with light-transmitting inks of dark blue, white and blue. 512 can be formed.

  The diffusion layer 513 is a textured transparent film that forms a diffusion surface that diffuses light incident from the back surface of the first display panel, and is adhered to the first display pattern forming layer 512 by a transparent adhesive member. Further, the diffusion layer 513 may be formed by printing the first display pattern formation layer 512 using a transparent ink. Each of the first base material 511, the first display pattern formation layer 512, and the diffusion layer 513 forming the first display plate 51 is transmissive to light. In the present embodiment, the first display pattern formation layer 512 and the diffusion layer 513 are disposed on the back side of the first base material 511, but the first display pattern formation layer 512 and the diffusion layer 513 are the first base material 511. It may be arranged on the front side. In the present embodiment, the first display pattern formation layer 512 and the diffusion layer 513 are arranged on the back side of the first base material 511 in the order of the first display pattern formation layer 512 and the diffusion layer 513 when viewed from the front. When viewed from the front, the diffusion layer 513 and the first display pattern forming layer 512 may be disposed in this order.

  4A is a partial perspective view of the light guide plate 52, and FIG. 4B is a partial side view of the light guide plate 52 along the propagation direction of light perpendicularly incident on the incident surface of the light guide plate from the first light source 53. It is sectional drawing.

  When the first light source 53 is turned on, the light guide plate 52 propagates the light from the first light source 53 while diffusing the light and emits the light toward the first display plate 51. The display board 51 is illuminated. In addition, when the second light source 55 is turned on, the light guide plate 52 transmits light emitted from the second light source 55 and transmitted through the second display plate 54 from the back to the front where the first display plate 51 side is located. Let Therefore, the light guide plate 52 is a sheet-like member having an area larger than the display area of the first display plate 51 and is disposed so as to face the back surface of the first display plate 51. The light guide plate 52 is formed by molding a resin that is transparent to light, such as polymethyl methacrylate, polycarbonate, or cycloolefin polymer. In one example, the thickness of the light guide plate 52 is 2 to 3 mm.

  A first incident surface 52 a facing the first light source 53 is formed on one side surface of the light guide plate 52, and light from the first light source 53 enters the light guide plate 52 from the first incident surface 52 a. The light propagating through the light guide plate 52 is totally reflected by the second incident surface 52b located on the back side and functioning as a diffusion surface, and then emitted from the emission surface 52c facing the back surface of the first display plate 51. Then, the light enters the first display panel 51.

  Further, when the second light source 55 is turned on, the light emitted from the second light source 55 and transmitted through the transmission region of the second display plate 54 is transmitted from the second incident surface 52 b of the light guide plate 52 to the light guide plate 52. Incident light passes through the light guide plate 52 as it is, and exits from the light exit surface 52 c toward the first display plate 51.

  In the present embodiment, the first incident surface 52a is formed so as to be orthogonal to the second incident surface 52b and the exit surface 52c. The first incident surface 52 a may be formed in a convex shape toward the first light source 53 so as to operate as a collimator lens so as to increase the directivity of light incident from the first light source 53.

  The second incident surface 52b is configured to reflect the light incident from the first incident surface 52a so as to be uniformly emitted from the entire emission surface 52c and to enter the first display plate 51 substantially perpendicularly. A plurality of prisms 521 are formed.

  The plurality of prisms 521 are formed side by side at a predetermined pitch along the propagation direction of incident light incident from the first incident surface 52a. Each prism 521 is formed on the second incident surface 52b as a substantially triangular groove extending in a direction substantially perpendicular to the propagation direction of incident light from the first incident surface 52a. Each prism 521 has a reflecting surface 522 that forms a predetermined angle with respect to the second incident surface 52b. The predetermined angle is determined according to the propagation direction of incident light and the direction in which light is emitted from the light guide plate 52. In the present embodiment, the propagation direction of incident light is substantially parallel to the second incident surface 52b, and the light guide plate 52 emits light substantially perpendicular to the emission surface 52c. Therefore, each reflective surface 522 is formed so as to form 37 ° to 45 ° with respect to the second incident surface 52b, for example. In this case, since the incident angle of the incident light with respect to each reflecting surface 522 is larger than the critical angle, the incident light is totally reflected at each reflecting surface 522 as indicated by an arrow 401. Therefore, the light guide plate 52 can suppress the amount of light that is not used for illumination of the first display plate 51 by suppressing the incident light from the first light source 53 from being emitted from the second incident surface 52 b side. In addition, the half-value angle of light emitted from the first light source 53 is, for example, ± 7 ° to ± 20 °, and the first light source center is parallel to the second incident surface 52b and the outgoing surface 52c. When the light source 53 is arranged, a viewing angle of 15 ° or more is secured.

  In addition, it is preferable that the pitch between the adjacent prisms 521 be constant so that the intensity of the light emitted from the emission surface 52c is uniform regardless of location. For example, each prism 521 is formed so that the pitch is approximately 100 μm.

  FIG. 5 is a diagram showing a table representing a relationship between a pattern density and a haze value, and an appearance of an object (not shown) arranged on the back surface of the light guide plate 52 by an observer by a visual experiment. In the table 500, the leftmost column represents the pattern density, the middle column represents the haze value, and the rightmost column represents the visual recognition result. In this experiment, one chip type white LED (LP-3020H196W) was used as the second light source 55. The haze value was measured using a haze meter HM-150L2 (manufactured by Murakami Color Research Laboratory Co., Ltd.). When the object illuminated by the second light source 55 is visually observed through the light guide plate 52 and the first display plate 51, the member in front of the object is felt to be a transparent member. OK, and NG when it was felt that there was an opaque member in front of the object.

  As shown in the table 500, when the pattern density exceeds 30% or the haze value exceeds 28%, the visual recognition result is NG. Therefore, for example, each prism 521 is preferably formed so that the pattern density is 30.0% or less. Alternatively, each prism 521 is preferably formed so that the haze value is 28% or less.

  The first light source 53 includes, for example, a light emitting element such as a white light emitting diode or a fluorescent lamp, and the light emitting surface thereof is disposed so as to face the first incident surface 52 a of the light guide plate 52. For example, the first light source 53 is arranged so that the direction in which the emission intensity is the highest is orthogonal to the first incident surface 52a. Moreover, as the 1st light source 53, in order to improve the utilization efficiency of light, it is preferable to use the light emitting element with directivity, for example. Alternatively, in order to increase the directivity of light emitted from the first light source 53, a collimator lens may be disposed between the first incident surface 52a and the first light source 53. Note that the first light source 53 may include a plurality of light emitting elements. The first light source 53 is turned on or off according to a control signal from the control unit 56.

  FIG. 6 is a side view of the second display panel 54.

  The second display board 54 is a flat member having a flat second base material 541 and a second display pattern forming layer 542. The second base material 541 is transparent to light in the same manner as the first base material 511. For example, the second base material 541 is formed by molding a resin transparent to the light of polymethyl methacrylate, polycarbonate, or cycloolefin polymer. . The second display pattern formation layer 542 presents the second display pattern when an observer located in front of the first display plate 51 observes the light from the second light source 55. It is formed by printing on one surface of the material 541 using ink that does not transmit light. The ink used when forming the second display pattern forming layer 542 is, for example, a pigment or dye that blocks light. The non-transmission region where the second display pattern formation layer 542 is formed does not transmit light, while the transmission region where the second display pattern formation layer 542 is not formed transmits light. The light from the second light source 55 that has passed through the transmission region that transmits light is transmitted to the first display plate 51 side that is located on the front side of the light guide plate 52. In one example, as shown in FIG. 2B, the second display pattern forming layer 542 is printed so that light can pass through a transmissive area indicating the English character string “CHANCE”. In the present embodiment, the second display pattern forming layer 542 is disposed on the back side of the second base material 541, but may be disposed on the front side of the second base material 541. Further, the second display panel 54 may be formed by molding an opaque resin into a flat plate shape. In this case, the transmission region is formed as one or a plurality of through holes that transmit light.

  The 2nd light source 55 is arrange | positioned at the back side of the 2nd display board 54, for example, has 1st light emitting element 551-6th light emitting element 556 provided with a white light emitting diode etc., and illuminates the 2nd display board 54. . Each of the first light emitting element 551 to the sixth light emitting element 556 irradiates any one of the transmission areas indicating the respective characters of the English character string “CHANCE” formed as a transmission area that transmits light to the second display panel 54. To be arranged. The illuminance by the light from the second light source 55 in the irradiation region irradiated with the light from the second light source 55 in the diffusion layer 513 is larger than the illuminance by the light from the first light source 53 in the irradiation region. It is preferable that light emitting elements having high luminance are selected as the first light emitting element 551 to the sixth light emitting element 556, respectively. When the first light source 53 is turned off and the second light source 55 is turned on by increasing the illuminance in the diffusion layer 513 by the light from the second light source 55, the first display on the first display plate 51 is displayed. This is to make the pattern appear white and make it difficult for the observer to visually recognize the first display pattern. When it is desired to illuminate the second display pattern with a light source of a specific color, a light emitting element such as a diode that emits light of the specific color may be used as the second light source 55. Similar to the first light source 53, the second light source 55 is turned on or off according to a control signal from the control unit 56.

  The control unit 56 includes, for example, a processor and a memory circuit, and controls the first light source 53 and the second light source 55 according to a control signal from a host control device (not shown). When displaying the first display pattern on the first display board 51, the control unit 56 turns on the first light source 53 and turns off the second light source 55. Further, when displaying the second display pattern on the second display board 54, the control unit 56 turns off the first light source 53 and turns on the second light source 55. The control unit 56 can repeat the alternating blinking of the first light source 53 and the second light source 55 at a predetermined cycle.

  The housing 57 houses the first display plate 51, the light guide plate 52, the first light source 53, the second display plate 54, and the second light source 55, and is fixed to the main body housing 1 by a fixing member (not shown).

  FIG. 7 is a diagram showing an example of a display pattern displayed on the display device, and FIG. 7A shows an example of the display pattern when the first light source 53 is turned on and the second light source 55 is turned off. FIG. 7B shows an example of a display pattern when the first light source 53 is turned off and the second light source 55 is turned on.

  When displaying the display pattern 603 shown in FIG. 7A, the control unit 56 turns on the first light source 53 and turns off the second light source 55. By turning on the first light source 53, the light from the first light source 53 is diffused by propagating through the inside of the light guide plate 52 and is emitted toward the first display plate 51. The light from the first light source 53 is diffused inside the light guide plate 52, so that the entire surface of the first display plate 51 is illuminated by the light from the first light source 53. Thereby, the first display pattern of the first display board 51 is displayed. On the other hand, since the second light source 55 is turned off, the second display pattern of the second display panel 54 is not displayed.

  When the display pattern 605 shown in FIG. 7B is displayed, the control unit 56 turns off the first light source 53 and turns on the second light source 55. By turning on the second light source 55, the light from the second light source 55 that has passed through the light-transmitting plate 52 and the transmission region corresponding to the second display pattern of the second display plate 54 is transmitted to the first display plate 51. The diffusion layer 513 is irradiated and diffused. The diffusion layer 513 functions as a transmission screen for displaying the second display pattern of the second display panel 54 by diffusing the light that has passed through the transmission region corresponding to the second display pattern in the diffusion layer 513. Since the light from the second light source 55 is transmitted through the transmission region corresponding to the second display pattern, when the light from the second light source 55 is incident, the first display plate 51 is not the entire surface but the first display plate 51. Only the area corresponding to the second display pattern of the two display board 54 appears to shine. Therefore, the second display pattern of the second display panel 54 is observed by the observer as displayed on the diffusion layer 513.

  The first display pattern is displayed according to the first display pattern forming layer 512 adjacent to the diffusion layer 513, and the second display pattern is displayed by the light diffused by the diffusion layer 513. There is no depth between the pattern and the second display pattern.

  As described above, the display device displays the first display pattern by irradiating the first display member with light from the first light source diffused by the light guide member. 1 The display member is illuminated over the entire surface. On the other hand, when the display device displays the second display pattern, the light from the second light source that has passed through the transmission region and the light guide plate according to the second display pattern of the second display plate 54 is changed to the first display pattern. By diffusing on the diffusing surface of the display member, the portion irradiated with the light from the second light source is lit on the diffusing surface of the first display member. For this reason, the observer who observes the first display pattern and the second display pattern can observe without feeling the depth between the first display pattern and the second display pattern.

  FIG. 8 is a diagram showing an example of a display pattern according to a modification of the first embodiment of the present invention. FIG. 8A shows that both the first light source 53 and the second light source 55 are turned off. 8B shows an example of the display pattern, and FIG. 8B shows an example of the display pattern when both the first light source 53 and the second light source 55 are turned on. When the display pattern of the modified example shown in FIG. 8B is displayed, the luminance of the first light source 53 and the second light source 55 can be displayed without causing the display pattern of the first display plate 51 to appear white. Adjusted to

  When displaying the display pattern 610 shown in FIG. 8A, the control unit 56 does not display both the first display pattern and the second display pattern, and the first light source 53 and the second light source 55. Turn off both of the lights. When the display pattern 611 shown in FIG. 8B is displayed, the control unit 56 displays the first light source 53 and the second light source 55 in order to display both the first display pattern and the second display pattern. Light. In addition to blinking the first light source 53 and the second light source 55 alternately, both the first light source 53 and the second light source 55 are simultaneously turned on and off to display on the display device 5. Various effects can be provided to an observer who observes the display pattern.

  FIG. 9 is a partially exploded perspective view of a display device according to the second embodiment of the present invention.

  The display device 6 according to the second embodiment is different from the display device 5 according to the first embodiment in having a second light source 65 instead of the second light source 55.
