BEST MODE FOR CARRYING OUT THE INVENTION
In the present embodiment, a display device and a gaming machine and a medal lending machine using the display device will be described. Note that the present invention is not limited to this embodiment.
[0015]
FIG. 1 is a perspective view showing a configuration of a display device 10 of the present invention. The display device 10 includes a rotating unit 11, two fixed shafts 12 and 13 that rotatably support the rotating unit 11, and a rotation driving unit that drives the rotating unit 11 to rotate around the fixed shafts 12 and 13. , A transmission board 15 that controls the entire display device 10, and a rotation position detection unit 16.
[0016]
The rotating unit 11 includes a first holding unit 20, a second holding unit 21, and a third holding unit 22 in which a plurality of light emitting diode (hereinafter referred to as LED) groups 17, 18, and 19 as a plurality of light emitting elements are arranged in a line. It is composed of two bearings 24 and 25 and two support parts 26 and 27 formed to make these three holding parts 20, 21 and 22 rotatable about the fixed shafts 12 and 13 as rotation centers. I have. These holding parts 20, 21, 22 are formed of a transparent resin, and as shown in the plan view of the rotating part 11 in FIG. 2, divide the circumference around the fixed shafts 12, 13 into three equal parts. Are located in That is, each of the three holding units 20, 21, 22 is arranged at a position rotated by 120 degrees. Further, the three holding portions 20, 21, 22 are connected to each other by support portions 26, 27, respectively, and further connected integrally to the bearings 24, 25. Further, of the two support portions 26 and 27, the upper support portion 26 has a receiver substrate 28 integrally formed on the upper surface. In the present embodiment, the fixed shaft is divided into two fixed shafts 12, 13, but the present invention is not limited to this, and one fixed shaft may be used.
[0017]
The LED groups 17, 18, and 19 are three types of LED groups that emit RGB light, which are the three primary colors of light. The LED group 17 is composed of LEDs that emit red light, the LED group 18 is composed of LEDs that emit green light, and the LED group 19 is composed of LEDs that emit blue light.
[0018]
The first holding unit 20 is a thin plate extending in the up-down direction and formed of a transparent resin, and is disposed so as to be in contact with the circumference around the fixed shafts 12 and 13 and to be parallel to the rotation center line CL. I have. FIG. 3 is a side cross-sectional view of the first holding unit 20 of the rotating unit 11. In the first holding unit 20, LED groups 17 that emit red light are arranged in a line along the vertical direction. Fixed. The first holding part 20 has a centrifugal surface 20B which is a surface facing the fixed shafts 12 and 13, and a centrifugal surface 20A which is a surface on the opposite side (a surface located outside during rotation). And
[0019]
The LED group 17 includes LEDs 17-1A to 17-16A fixed to the centrifugal surface 20A at the same position in the length direction of the first holding unit 20, and LEDs 17-1B to 17-16B fixed to the centripetal surface 20B. Are arranged in pairs. Thereby, the LED groups 17 are arranged in a line on the centrifugal surface 20A and the centripetal surface 20B so as to be parallel to the rotation center line CL of the rotating unit 11. Therefore, when the rotating unit 11 is driven to rotate, the trajectory of the LED group 17 describes a cylindrical surface.
[0020]
In addition, since the LED group 17 is arranged on both sides of the centrifugal surface 20A and the centrifugal surface 20B of the holding unit 20, when the display device 10 is viewed from outside the rotation area of the first holding unit 20, the first holding unit is used. In an area where 20 is closer to the front of the fixed shafts 12 and 13 (on the front side in the observation direction), display is performed by the LEDs 17-1A to 17-16A fixed to the centrifugal surface 20A, and the first holding unit 20 is closer to the fixed shafts 12 and 13. In an area located far away (far side in the observation direction), display is performed by the LEDs 17-1B to 17-16B fixed to the centripetal surface 20B.
[0021]
The second holding unit 21 has the same configuration as the first holding unit 20, and the LED groups 18 that emit green light are arranged and fixed in a line along the vertical direction, and are fixed. The light emitting diodes 18-1A to 18-16A fixed to the centrifugal surface 21A at the same position in the length direction and the light emitting diodes 18-1B to 18-16B fixed to the centripetal surface 21B are arranged as a unit. Have been.
[0022]
The third holding unit 22 also has the same configuration as the first holding unit 20, and the LED groups 19 that emit blue light are arranged and fixed in a line along the up-down direction, and are fixed. The LED 19-1A to 19-16A fixed to the centrifugal surface 22A at the same position in the length direction and the LEDs 19-1B to 19-16B fixed to the centripetal surface 22B are arranged as a unit.
[0023]
As described above, in the present embodiment, the LED groups 17, 18, and 19 are used as a plurality of light emitting elements. Since the switching time of the LED is shorter than that of a general light bulb, even when the holding units 20, 21, and 22 are rotated at a high speed, it is possible to switch a number of times during one rotation, and a complicated display is performed. It can be performed. In addition, since LEDs have a longer life than ordinary light bulbs, maintenance costs can be reduced. Also, the description has been made such that 16 pairs of LED groups 17, 18, 19 are arranged in the three holding units 20, 21, 22. However, the display device of the present invention employs an arbitrary number of LEDs in the holding units 20, 21, 22. You may arrange | position and comprise.
[0024]
The rotation drive unit 14 includes a motor 29 and a gear 30. In the present embodiment, an example in which a DC motor is used as the motor 29 will be described. The driving of the motor 29 is transmitted via a gear 30 to a gear 24 a formed on the upper part of the outer peripheral surface of the bearing 24. Since the rotating unit 11 is rotatably supported by the fixed shafts 12 and 13, when the driving of the motor 29 is transmitted to the gear 24a, the rotating unit 11 performs the rotational driving. Thereby, the LED groups 17, 18, and 19 arranged in the three holding units 20, 21, and 22 are driven to rotate together with the holding units 20, 21, and 22. By this rotation drive, it is possible to perform display over the entire area covered by the rotation of the LED groups 17, 18, and 19, using the afterimage phenomenon in the human optic nerve. However, since the afterimage phenomenon is used, the rotational drive needs to be performed sufficiently quickly. In order to prevent the display from flickering, for example, it is preferable to set the cycle of the rotation drive to 12 ms or less.
[0025]
Further, the rotation position detection unit 16 detects that the rotation unit 11 is at a predetermined rotation position. The rotational position detector 16 includes an index sensor 16a and an index 16b. The index sensor 16a is disposed on the fixed shaft 12, and the index 16b is disposed on the upper surface of the bearing 24. The index sensor 16a is provided with a photodiode (not shown) and a phototransistor (not shown), and a phototransistor (not shown) is arranged to receive light from the photodiode. ing. The index 16b is arranged so that when the bearing 24 is at a predetermined rotational position, the index 16b blocks light from the photodiode to the phototransistor. Thereby, a predetermined rotation position of the rotating unit 11 is detected. This predetermined rotation position can be set as the display start position of the three holding units 20, 21, 22.
[0026]
Further, it is possible to detect the rotation cycle of the holding units 20, 21, 22 by the rotation position detection unit 16. Further, the rotation position detection unit 16 acquires signals corresponding to the front surface display start position and the back surface display start position of the LED groups 17, 18, 19, and performs display in synchronization with the signals. You may do it.
[0027]
Next, the electrical configuration of the display device 10 will be described. FIG. 4 is a block diagram illustrating an electrical configuration of the display device 10. The display device 10 is provided with a control unit 31 as control means for controlling the entire display device 10 on the transmit board 15, and is connected to the motor 29 and the rotational position detection unit 16. Further, a parallel-serial conversion unit 34 and an infrared transmitter 35 as a conversion unit are provided on the transmission substrate 15 and connected to the control unit 31, which is controlled by the control unit 31. Further, the transmit board 15 is connected to a power supply 32, and power is supplied to each unit in the transmit board 15.
[0028]
The control unit 31 controls the parallel-serial conversion unit 34 to convert a display signal displayed by the display device 10 from a parallel signal to a serial signal and output the signal. The display signal converted into the serial signal is transmitted to the infrared transmitter 35, where it is converted into an infrared signal which is an optical signal.
[0029]
The receiver substrate 28 of the rotating unit 11 is provided with an infrared receiver 36 as a re-converting unit, a serial-to-parallel converting unit 37, and a driving circuit 38 as a light-emitting element driving circuit. The infrared receiver 36 is provided in the bearing 24 and is connected to the above-mentioned infrared transmitter 35 via an optical fiber 39. The infrared light output from the infrared transmitter 35 propagates through the optical fiber 39 and enters the infrared receiver 36. The infrared receiver 36 converts the infrared signal output and transmitted from the infrared transmitter 35 again into a serial signal display signal. Thereby, the display signal is transmitted to the infrared receiver 36 of the rotating unit 11.
[0030]
The serial-parallel converter 37 converts the serial signal display signal converted by the infrared receiver 36 into a parallel signal display signal. Thereafter, the display signal of the parallel signal is received by the drive circuit 38, and the drive circuit 38 drives the LED groups 17, 18, and 19 based on the signal. The drive circuit 38 may be formed on the support portions 26 and 27 without being formed on the receiver substrate 28, or may be formed on the holding portions 20, 21 and 22.
[0031]
The above-described bearing 24 is provided with a slip ring (not shown) as a conductive mechanism for conducting from the fixed shaft 12 to the bearing 24, and the power supplied from the power supply 32 to the transmitter board 15 is transmitted through the slip ring. It is supplied to each part of the rotating part 11. Therefore, power can be reliably supplied to the drive circuit 38 and the like provided on the receiver substrate 28 via the slip ring irrespective of the rotation of the rotating unit 11, and the optical fiber 39 for transmitting the infrared signal can be supplied. Also, the rotating unit 11 can rotate without being hindered by wiring for power supply.
[0032]
Note that the conductive mechanism is not limited to the slip ring, and any other mechanism may be used as long as the mechanism allows the fixed shaft 12 to conduct to the bearing 24. For example, power may be supplied to the drive circuit 38 and the like using an electromagnetic induction coil that transmits power in a non-contact manner. As a result, power is supplied to the drive circuit 38 via the electromagnetic induction coil that transmits electric power in a non-contact manner, so that the receiver formed on the support portion 26 of the rotating portion 11 is not hindered by the rotation of the rotating portion 11. Power can be supplied to a drive circuit 38 provided on the substrate 28 and the like.
[0033]
Also, it has been described that the display signal converted into the serial signal is transmitted as an optical signal from the transmitter substrate 15 to the receiver substrate 28 provided on the rotating unit 11 via the optical fiber 39. The displayed display signal may also be transmitted from the transmitter substrate 15 to the receiver substrate 28 via the above-described slip ring. In this case, the infrared transmitter 35 as the conversion unit, the optical fiber 39, and the infrared receiver 36 as the re-conversion unit become unnecessary.
[0034]
The control unit 31 includes, for example, a central processing unit, a storage device, a program stored in the storage device, and an interface for each unit to be controlled. The control unit 31 holds the brightness of the LED groups 17, 18, and 19, The control is performed based on the rotational positions of 21 and 22 and the display signal. Therefore, the control unit 31 exchanges signals with the rotation drive unit 14, the rotation position detection unit 16, the infrared transmitter 35, the infrared receiver 36, and the drive circuit 38. The control unit 31 can also be configured by a logic circuit and an interface to each unit to be controlled.
[0035]
Hereinafter, the operation of the above-described display device 10 will be described with reference to the flowchart of FIG. The power supply 32 supplies power to each unit in the transmission board 15. The electric power drives the motor 29 of the rotation drive unit 14. Further, the control unit 31 acquires information on the predetermined rotation position and the rotation period T from the rotation position detection unit 16. The control unit 31 converts the display signal from a parallel signal to a serial signal and outputs the signal by controlling the serial-parallel conversion unit 34 based on the position information. In the present embodiment, when the first holding unit 20 is at the reference position A, the control unit 31 detects a signal from the rotation position detection unit 16.
[0036]
The above-described parallel signal will be described below. In the present embodiment, an example in which the character string “BIG” is displayed in yellow will be described. When the display is performed in yellow, the red (R), green (G), and blue (B) lights are combined by combining the red (R) and green (G) lights out of the red (R), green (G), and blue (B). No light is needed. That is, when displaying in yellow, the LED groups 17 and 18 need to emit light, and the LED group 19 does not need to emit light.
[0037]
FIG. 6 is a timing chart of the LED group 17 that is arranged in the first holding unit 20 and emits red light. FIG. 6A shows a lighting position of the LED group 17 corresponding to a rotation position of the rotating unit 11 when a character string “BIG” is displayed. While the first holding unit 20 rotates from the position of the reference position A to the reference position B, the display on the centrifugal surface 22A side is performed by switching the LEDs 17-1A to 17-16A on the centrifugal surface 20A side. .
[0038]
While the first holding unit 20 rotates from the reference position B to the reference position A, switching of the LEDs 17-1B to 17-16B on the centripetal surface 20B performs display on the centripetal surface 20B side. .
[0039]
FIG. 6B is a timing chart of a display signal for lighting the LEDs 17-1A to 17-16A and 17-1B to 17-16B in accordance with the lighting position of the LED group 17. In the display by the LED group 17, for example, all the LEDs are turned off at the rotation position P1 of the rotating unit 11, the LEDs 17-10A to 17-13A are turned on at the rotation position P2, and the LEDs 17-6A to 17-8A at the rotation position P3. , And 17-10A to 17-12A are turned on.
[0040]
The timing chart of the LED group 18 that emits green light and is arranged in the second holding unit 21 is the same as the timing chart of the LED group 17 shown in FIG. The second holding unit 21 reaches the reference position A when the holding unit 20 rotates 120 degrees after passing the reference position A. At this time, the LED group 18 starts displaying on the centrifugal surface 21A side. While rotating from the reference position A to the reference position B, the display on the centrifugal surface 21A side is performed by switching the LEDs 21-1A to 21-16A on the centrifugal surface 21A side.
[0041]
While the second holding unit 21 rotates from the reference position B to the reference position A, switching of the LEDs 21-1B to 21-16B on the centripetal surface 21B performs display on the centripetal surface 21B side. .
[0042]
When the character string “BIG” is displayed in yellow, the LED group 19 that emits blue light in the third holding unit 22 does not need to emit light, so the display signal does not cause all of the LED groups 19 to emit light. Signal.
[0043]
Although the case where the character string “BIG” is displayed in yellow has been described, the present invention is not limited to this, and the image may be displayed in full color. In this case, the control unit 31 does not control only the two stages of lighting and non-lighting of the LED groups 17, 18, and 19, but the control unit 31 adjusts the brightness of the LED groups 17, 18, and 19 in many stages. By controlling and synthesizing red (R), green (G), and blue (B) light emitted from the LED groups 17, 18, and 19, a full-color display may be performed.
[0044]
The switching and brightness of the LED groups 17, 18, and 19 are controlled such that one rotation is defined as one cycle T. For example, when the display is performed as shown in FIG. The image is displayed by the afterimage effect by controlling the switching and brightness and changing the display pattern. In the present embodiment, the switching of the LEDs 17, 18, and 19 and the control of the brightness are performed at a time obtained by dividing the cycle T by 50. However, the present invention is not limited to this. , 19 may be controlled and the brightness may be controlled. Further, the time of 50 divisions may be further divided into 4 to control the turning on / off of the LEDs. In this case, there is an advantage that the brightness can be controlled.
[0045]
The parallel signal generated as described above is transmitted to the parallel-serial conversion unit 34 and converted into a serial signal. This serial signal is transmitted to the infrared transmitter 35 and converted into an optical signal, and the infrared light, which is an optical signal, propagates through the optical fiber 39 and is transmitted to the infrared receiver 36.
[0046]
The infrared receiver 36 converts the received infrared light signal into a serial signal again and transmits the serial signal to the serial-parallel conversion unit 37. The serial-parallel converter 37 converts this serial signal into a parallel signal. This parallel signal is similar to the parallel signal shown in FIG. 6, and this parallel signal is transmitted to the drive circuit 38. The drive circuit 38 causes the LEDs 17, 18, and 19 at the corresponding positions to emit light based on the parallel signal, and displays the light.
[0047]
In this display, since the three holding parts 20, 21, 22 are formed of a transparent resin, for example, the first holding part 20 is on the back side in the viewing direction, and the second holding part 21 is on the near side in the viewing direction. Side, the light emitted from the side of the centripetal surface 20B of the LED group 17 of the first holding unit 20 is not blocked by the second holding unit 21. For this reason, the red character string “BIG” displayed by the LED group 17 and the green character string “BIG” displayed by the LED group 18 overlap, and the display surface has a yellow character string as shown in FIG. The character string "BIG" is displayed. FIG. 7A shows a display surface formed by the LEDs 17-1A to 17-16A and LEDs 18-1A to 18-16A on the centrifugal surfaces 20A and 21A, and FIG. 7B shows the LEDs 17-1 on the centripetal surfaces 20B and 21B. 1B to 17-16B and display surfaces by LEDs 18-1B to 18-16B.
[0048]
The display as described above is repeatedly performed over several cycles (several rotations). The control unit 31 determines whether to end the display. If it is determined that the display is not to be ended, the display is continued. If it is determined that the display is to be ended, the control unit 31 stops the motor 29, and the display process ends.
[0049]
As described above, the holding units 20, 21, 22 provided with the LED groups 17, 18, 19, which are the three primary colors of light, are rotationally driven to control the switching and brightness of the LED groups 17, 18, 19. Since a full-color image can be displayed on the cylindrical surface, the effect of rendering is improved as compared with the case where the image is displayed in a single color on the display surface.
[0050]
In the present embodiment, the three holding units are arranged at positions rotated by 120 degrees about the fixed axis, but the present invention is not limited to this. In addition, the holding unit is configured by a transparent thin plate arranged so as to be parallel to the fixed axis direction, and the LED group is linearly arranged. However, the present invention is not limited to this, and the holding unit is arranged in the fixed axis direction. The LED group may be arranged in a line shape in an extended shape. For example, a transparent thin plate may be arranged in the direction of the fixed axis, and may be curved in the direction of the fixed axis to form an arc having a center on the rotation center line of the rotating unit. In this case, since the LED group is arranged in an arc shape, the display surface can be made spherical. Further, the holding portion may be formed of a plurality of transparent thin plates, and the LED groups may be arranged in a straight line in a bent shape.
[0051]
In the present embodiment, the LEDs are provided on the centrifugal surface and the centripetal surface of the holding unit. However, the present invention is not limited to this, and the LEDs may be provided only on the centrifugal surface. In this case, a reflector may be provided on the back side of the display device, and when the centrifugal surface rotates to the back side, the light of the LED disposed on the centrifugal surface may be reflected by the reflector.
[0052]
Furthermore, in the present embodiment, an example in which a DC motor is used as the motor 29 has been described. However, the present invention is not limited to this, and a pulse motor may be used, for example. In this case, since the control unit 31 controls the speed of the pulse motor, only the information on the predetermined rotation position (display start position) needs to be acquired from the rotation position detection unit 16.
[0053]
Next, a slot machine 50 as a gaming machine using the display device 10 will be described. FIG. 8 is an external perspective view of the slot machine 50. The slot machine 50 has a rectangular box-shaped casing 51, and a display section 52 to be observed on the player side is formed in a central portion and an upper portion of the casing 51. In the center of the display section 52, a symbol display window 54 through which symbols of three rotating reels 53a, 53b, 53c can be seen, and a display device window 55 are formed. The display device 10 is attached to the housing 51 such that the LEDs 20 and 21 move within a range visible from the display device window 55. Hereinafter, the slot machine 50 will be briefly described.
[0054]
