Description

  The present invention relates to a rotary display device that includes a rotary display member that is rotationally driven and a light source device, and displays information such as characters and graphics on a rotary peripheral surface of the rotary display member.

  Since the rotary display device as described above can display characters and figures as if they are spatially lifted, it can be distinguished from other gaming machines such as pachinko machines, arrange ball machines and slot machines.

  In the pachinko machine PM generally configured as described above, a configuration example of the rotation display device 100 provided in the central ornament 20 is shown in each of FIGS. Here, FIG. 3 is an exploded perspective view of the rotary display device 100, FIG. 4 is a side sectional view of the rotary display device 100 along the motor axis, and FIG. 5 is viewed in the direction of arrows VV in FIG. FIGS. 6A, 6B and 6C are member diagrams (three views) of a holder plate constituting the rotation display member 120 in the rotation display device 100, and FIGS. 7A and 7B are views of the light source device. It is drawing (plan view and sectional drawing) which shows a structure form. In the following, for convenience of explanation, the upper, lower, left, and right directions in FIG.

  The rotary display device 100 is mainly configured by a rotary display member 120 rotated by a motor 110 and a light source device 160 (161, 162) fixed and held facing a side end surface of the rotary display member 120. The motor 110 is an electric motor that rotates the rotation display member 120 at a predetermined number of revolutions of 1200 rpm or more, and can be configured using, for example, a commercially available DC motor.

  The rotation display member 120 includes a light guide member holder 125 and a plurality of light guide members 140 and 150 fixedly held by the light guide member holder 125. The light guide member holder 125 includes a cylindrical boss portion 123 that is fitted and connected to the output shaft 116 of the motor 110, and flat plate-like substrate portions 121 and 122 that protrude radially outward from the boss portion 123. In the embodiment, two substrate portions (first substrate portion 121 and second substrate portion 122) are formed at a rotationally symmetric position of 180 degrees around the axis (rotation axis) CL of the boss portion 123. In addition, the light guide member holder 125 is formed by forming two front and rear holder plates 125a and 125b divided at the center of the thickness of the first substrate portion 121 and the second substrate portion 122 by molding means such as injection molding. A configuration example in which the light guide members 140 and 150 are sandwiched between two holder plates 125a and 125b and integrated by a bonding means such as adhesion, welding, a lock claw, or a screw is shown.

  The holder plates 125a and 125b are formed with grooves for positioning and fixing the light guide member. As shown in three views of one holder plate 125a in FIGS. 6A, 6B, and 6C, a plurality of first light guide members 140 are fixed to the first plate portion 126 that forms the first substrate portion 121. A first groove portion 131 for holding is formed, and a second groove portion 132 for positioning and fixing the plurality of second light guide members 150 is formed on the second plate portion 127 forming the second substrate portion 122. . Here, the number of the first light guide members 140 and the second light guide members 150, that is, the number of channels in the axial direction (the number of scanning lines) in the rotary display device is arbitrarily set according to the definition of information to be displayed. In the embodiment, the number of the first and second light guide members 140 and 150 is eight (141 to 148 and 151 to 158), and the eight grooves corresponding to the first and second grooves are first groove portions. The example of a structure which formed 131a-131h and the 2nd groove part 132a-132h is shown.

  The first groove portions 131a to 131h and the second groove portions 132a to 132h are each formed between a side end surface (upper and lower end surfaces in each figure) extending in the radial direction and a rotating end surface extending in the axial direction in the plate portions 126 and 127. The cross section is formed in a semicircular groove shape. The first and second groove portions of the other holder plate 125b are formed symmetrically with respect to the split surface (surface of the plate portion). For this reason, when the front and rear holder plates 125 a and 125 b are overlapped, a bent hollow fixing hole is formed inside the first substrate portion 121 and the second substrate portion 122.

On the other hand, the first groove portions 131a to 131h and the second groove portions 132a to 132h rotate around an axis that intersects with the rotation axis CL and extends in a direction orthogonal to the substrate portion at the vertical center height of the first and second substrate portions 121 and 122. It is formed symmetrically, and the side end surfaces where the groove portions open are upside down in the first substrate portion 121 and the second substrate portion 122. That is, the first groove portions 131 a to 131 h and the second groove portions 132 a to 132 h have the same height position of the grooves arranged on the rotation end surface of each substrate portion, but the first groove portions 131 a to 131 h are the same as those of the first substrate portion 121. The second grooves 132a to 132h are formed at predetermined radial positions r _{1 to} r ₈ along the lower side end surface, and the second grooves 132a to 132h have the same radius as the first groove along the upper side end surface of the second substrate 122. They are formed at predetermined positions r _{1 to} r ₈ in the direction.

  The first light guide member 140 (141 to 148) and the second light guide member 150 (151 to 158) fixedly held in these grooves have a lower refractive index than the core that transmits light and the outer periphery of the core. It is a rod-shaped optical transmission member having a covering clad and having a flexible fiber shape or a predetermined shape. Light incident from one end (light receiving portion) 141i, 142i... 148i, 151i, 152i. It transmits, and it radiate | emits from the other end (light emission part) 141k, 142k ... 148k, 151k, 152k ... 158k.

  Specifically, an optical fiber or light guide made of glass or plastic having an appropriate shape and dimension can be used. For example, a plastic optical fiber (POF) having a diameter of about 1 to 3 mm is used as the first and second grooves 131a to 131h. , 132a to 132h are used by being bent and molded. The light guide members 140 and 150 are configured such that the light receiving portion i side protrudes from the side surfaces of the first and second substrate portions 121 and 122 by a predetermined amount. As is clear from the above description, the first groove portion 131 and the second groove portion 132 have the same shape of the groove portions common to the subscripts a to h, such as 131a and 132a and 131b and 132b. Yes, the first and second light guide members 140 and 150 at the end 1 to 8 corresponding thereto are configured as common parts.

  The holder plates 125a and 125b have a plurality of alignment fitting projections 128p and projection receiving holes 128h formed at symmetrical positions in the vertical and horizontal directions. When these are fitted, the first substrate portion 121 and The groove portions 131a to 131h and 132a to 132h of the second substrate portion 122 are aligned to form a communication hole having a circular cross section whose diameter is the same as or slightly larger than that of the light guide member. Therefore, the first and second light guide members 141 to 148 and 151 to 158 are fitted in the first and second groove portions 131a to 131h and 132a to 132h, and the fitting protrusions 128p are fitted to the fitting receiving holes 128h. When the front and rear holder plates 125a and 125b are joined by joining means such as adhesion, the light guide members 140 and 150 are fixedly held in a state where they are positioned in the front and rear grooves, and an integral rotation display member 120 as shown in FIG. Is formed.

  In the rotation display member 120 formed in this way, in the first substrate portion 121, the light receiving portions 141i to 148i of the first light guide members 141 to 148 protrude and are arranged in the radial direction on the lower side end surface 121d. The light emitting portions 141k to 148k are arranged vertically on the rotation end surface 121s. In the second substrate portion 122, the light receiving portions 151i to 158i of the second light guide members 151 to 158 are arranged to protrude in the radial direction on the upper side end surface 122u, and the light emitting portions 151k to 158k are rotated end surfaces 122s. Are arranged side by side.

  The rotation display member 120 includes a light guide member holder 125 and light guide members 140 and 150, and no electronic components such as a light emitting element and a memory are provided. Therefore, it is possible to prevent the component from being damaged due to the high-speed rotation of the electronic component and to configure the rotary display member 120 to be small and light. Moreover, the arrangement pitch of the light emitting units 141k to 148k can be reduced to near the diameter size of the light guide member 140, and the light projecting units 171 to 171 which require a certain width depending on the light source size (for example, the external dimensions of the LED). The light emitting portions can be arranged at a pitch smaller than the pitch between the columns of 178 (compare FIG. 4 and FIG. 6).

  As indicated by a two-dot chain line in FIG. 6, a hole A having the same shape is formed through the substrate portion at the same radial position of the first and second substrate portions 121 and 122, or the first The second substrate portions 121 and 122 may have a rotationally symmetric frame configuration B. According to such a configuration, the moment of inertia and the air resistance of the rotation display member 120 can be reduced, thereby reducing the required rotation torque of the motor 110 and further reducing the size and cost of the rotation display device 100. can do. Further, the light emitting members 131k to 138k and 141k to 148k may be formed by forming the tip of each light guide member into a spherical shape, and a member for diffusing light in the light emitting unit, for example, a diamond-cut plastic lens, A milky white transparent prism sheet may be bonded and fixed to the rotating end faces 121 s and 122 s of the substrate unit, or a fluorescent chip that generates fluorescence by light from a light source may be provided. According to such a configuration, visibility can be improved by widening the viewing angle.

  On the other hand, the light source device 160 includes a first light source device 161 provided below the rotation display member 120 facing the lower side end surfaces 121d and 122d of the first and second substrate portions, and a first and second substrate. And the second light source device 162 provided above the rotation display member 120 so as to face the side end surfaces 121u and 122u on the upper side of the unit, and the first light source device 161 and the second light source device 162 sandwich the rotation display member 120 therebetween. It is fixedly arranged facing the top and bottom.

The first light source device 161 and the second light source device 162 are provided along the rotation trajectories of the light receiving portions 141 i to 148 i and 151 i to 158 i when the rotation display member 120 is rotated about the rotation axis CL by the motor 110. And 8 rows of light projecting sections facing each light receiving section. That is, in the first light source unit 161, at the same radial position r ₁ ~r ₈ and the light receiving portions 141i~148i of the first light guide member, the first projecting the first row L ₁ ~ eighth row L ₈ The light portions 171 to 178 are provided concentrically, and in the second light source device 162, the first row L ₁ is located at the same radial positions r _{8 to} r ₁ as the light receiving portions 151i to 158i of the second light guide member. The second light projecting portions 181 to 188 in the eighth row L ₈ are provided concentrically.

For this reason, the light emitted from the first light projecting units 171 to 178 in the first column L ₁ to the eighth column L ₈ is incident on the light receiving units 141 i to 148 i of the first light guide members facing each other and is first. It propagates through the light guide members 141 to 148 and is emitted from the first light emitting portions 141k to 148k which are output ends of the light guide members. Similarly, the light emitted from the second light projecting portions 181 to 188 in the first row L ₁ to the eighth row L ₈ is incident on the light receiving portions 151 i to 158 i of the second light guide members facing each other, and the second light guide. It propagates through the optical members 151 to 158 and is emitted from the second light emitting units 151k to 158k. Then, information is displayed on the rotation peripheral surface of the rotation display member 120. The principle that information is displayed by the rotation of the rotation display member 120 is schematically shown in FIG.

The rotation display member 120 is rotated at a high speed by the motor 110, and the rotation end surface 121s of the first substrate unit 121 and the rotation end surface 122s of the second substrate unit alternately alternate the front of the player from left to right (or from right to left). Move to. The motor 110 rotates at a constant speed, and the trajectory of the tip of the first substrate 121 at time t ₂ , t ₃ , t ₄ ... T ₈ every fixed minute time dt from time t ₁ is shown in FIG. The first to eighth light emitting portions 141k to 148k move horizontally on the rotating circumferential surface S at regular intervals.

At this time, the individual position of the first through eighth light-emitting unit 141k~148k at each time are projected onto a plane is FIG. 8 (b), the at time t ₁ ~t _8, first through eighth light-emitting The first row m ₁ to the eighth row m ₈ in the vertical direction in which the portions 141k to 148k are arranged, and the first row n ₁ to the eighth column n _{8 in} the horizontal direction (time axis direction) in which each light emitting portion moves 8 rows × The matrix is 8 columns. Therefore, lighting of the first light projecting units 171 to 178 in the first column L ₁ to the eighth column L ₈ of the first light source device 161 is controlled to light up and the first to eighth light emitting units 141k to 148k are turned on. Alternatively, by blinking, various information such as characters and figures composed of 8 rows × 8 columns of dots can be displayed.

  The information display by the second substrate unit 122 is the same, and the light projecting units in the same angle region (for example, reference numerals 161a and 162a in FIG. 4) in the first light source device 161 and the second light source device 162 that are vertically opposed to each other are simultaneously displayed. When the lighting or blinking control is performed, different information is overlapped and spatially raised due to the afterimage phenomenon of each light emitting part of the first board part 121 and the second board part 122 that alternately move in front of the player. It can be carried out. Further, when different angle regions (for example, reference numerals 161a and 162b in FIG. 4) in the first light source device 161 and the second light source device 162 are simultaneously turned on or blinked, the same or different information is spatially raised at different positions. Can be displayed.

Here, the first light source device 161 and the second light source device 162 include the first light projecting units 171 to 178 and the second light projecting units of the first row L ₁ to the eighth row L ₈ that are provided adjacent to each other in the radial direction. Concentric shielding walls 179 and 189 that are positioned between the light portions 181 to 188 and partition the rows are formed, and the protruding ends of the light receiving portions 141i to 148i and 151i to 158i corresponding to the light projecting portions of the rows. Are configured to be positioned between adjacent shielding walls 179: 179, 189: 189 arranged in parallel. For this reason, the light emitted from each light projecting unit does not enter the other light receiving units, and is always received by the light receiving units in the row corresponding to the light projecting units at 1: 1. Therefore, even if the light projecting portions 171 to 178 and 181 to 188 are arranged at a high density in the radial direction, no signal interference occurs between the adjacent light projecting and receiving portions, and crosstalk is reduced to reduce characters and characters. A rotary display device capable of clearly displaying figures and the like can be configured compactly.

  9 to 11 show the configurations of the first and second light source devices 161 and 162 of the first embodiment. Below, in order to distinguish from the light source device of 2nd Embodiment mentioned later, the 1st light source device 161 and the 2nd light source device 162 are displayed as the light source device 210, and the example applied to a 1st light source device is demonstrated. 9 is a block diagram illustrating an outline of the light source device 210 of the present embodiment, FIG. 10 is a configuration diagram illustrating a detailed configuration of the first light projecting units 171 to 178 in the light source device 210, and FIG. It is explanatory drawing for demonstrating.

  The light source device 210 includes an angle detector 211 that detects a rotation angle position of the rotation display member 120 and a rotation that controls blinking of the first light projecting units 171 to 178 based on a detection signal input from the angle detector 211. And a display control unit 212. The rotation display control unit 212 is provided on an effect control board that controls the operation of the liquid crystal display panel 25 and other lighting devices, and information display control is performed in accordance with the game development status.

The angle detector 211 is a detector that detects the azimuth angle of the first substrate unit 121 (or the second substrate unit 122) of the rotary display member 120 with respect to the light source device 210, and, for example, turns by the rotation of the rotary display member 120. When the first substrate 121 passes through the angle position t ₀ shown in FIG. 11, it is configured using a photo interrupter, a proximity sensor, or the like that detects the passage timing.

As shown in FIG. 10, the first light projecting units 171 to 178 in the light source device 210 concentrate the light emitted from the light source 213, the ring-shaped light emitter 215, and the light source 213 on the light emitter 215. Eight lenses are provided corresponding to each of the first column L ₁ to the eighth column L ₈ . As the light source 213, a solid-state light-emitting element capable of switching (flashing operation) at a high speed, such as a monochromatic or full-color high-intensity LED or a laser diode is used. The light emitter 215 has a certain light diffusibility by adding a fine light scattering material to a member that emits light from the entire ring when light emitted from a light source (illumination light) is incident, for example, a core made of a translucent material. And a light guide member for backlight or ring illumination that forms a reflection surface on the rear side of the translucent part and emits light all around the light guide.

Then, the rotation display control unit 212 controls the operations of the light sources 213, 213,... In the first column L ₁ to the eighth column L ₈ based on the detection signal input from the angle detector 211. The blinking of the light parts 171 to 178 is controlled to display information on the rotation peripheral surface S of the first substrate part 121.

That is, as already described with reference to FIG. 8, the rotation display member 120 rotated by the motor 110 rotates at a substantially constant rotation speed. Therefore, if the rotational angular position detected in the first substrate portion 121, the rotation end face 121s of the first substrate portion for each time point t ₁ after a certain minute time dt is passing the position of t _2, t ₃ ... t ₈ In addition, a matrix of 8 rows × 8 columns can be formed by the first to eighth light emitting portions 141k to 148k.

Therefore, in the light source device 210 of the present embodiment, the timing at which the first substrate unit 121 passes through the angle position t ₀ is detected by the angle detector 211, and then the t ₁ position reached after elapse of a certain delay time δt, And the first light projecting portions 171 to 178 of the first column L ₁ to the eighth column L ₈ in accordance with the time positions t ₂ , t ₃ , t ₄ ... T ₈ that arrive at a constant minute time dt interval from t _1. The flashing operation of each of the light sources 213, 213,. For example, as shown in FIG. 11A, the light sources 213 of the first light projecting portions 171, 172, and 173 in the first, second, and third rows L ₁ , L ₂ , and L ₃ are turned on at time t ₁ . At time t ₂ , t ₃ , t ₄ , only the light source 213 in the first column L ₁ is turned on, and at time t ₅ , the first column L ₁ and the sixth, seventh, and eighth columns L ₆ , L ₇ , L _The number “7” can be displayed as shown in FIG. 5B by turning on the light sources 213 of ₈ and blinking the light sources in each column in the same manner. Information such as other numbers, characters, figures, etc. can be displayed by the same blinking control.

Further, by changing the minute time dt between t ₁ , t ₂ , t ₃ ... T ₈ , the width of the information displayed on the rotating circumferential surface S can be changed, for example, the minute time dt is gradually increased. By doing so, a dynamic display in which the font of the number “7” gradually changes to landscape can be performed. Further, by changing the delay time δt between t ₀ and t ₁ , the position of the information displayed on the rotation circumferential surface S can be changed in the left-right direction. For example, by gradually increasing the delay time δt, the numeral “7 Can be displayed dynamically. Note that the rotation speed of the rotation display member can be calculated from the interval of the passage time of the first substrate portion 121 detected by the angle detector 211 (a plurality of detection intervals of t ₀ ), and thereby a reference delay By correcting the time δt and the minute time dt, accurate information can always be displayed at the correct angular position.

  Therefore, information that is spatially floating can be obtained without using an expensive detector such as a potentiometer or a rotary encoder that constantly detects the angular position of the rotation display member 120, and with a simple device configuration that blinks the eight light sources 213. It can be displayed in various display modes.

  In addition, although the Example demonstrated the structural example which formed the 1st light projection parts 171-178 in the ring shape with the one ring-shaped light-emitting body 215, respectively, each light projection part was divided | segmented into multiple in the circumferential direction. An arcuate light emitter may be provided for each region, and the light emitter is provided in a certain angle range (for example, an angle range of 120 degrees in front of the pachinko machine) according to the display range of the rotary display device 120. May be.

  Next, the 1st, 2nd light source device 161,162 of 2nd Embodiment is demonstrated with reference to FIG.12 and FIG.13. Hereinafter, in order to distinguish from the light source device 210 of the first embodiment, the first and second light source devices 161 and 162 of the second embodiment are displayed as the light source device 220, and the application example to the first light source device is the same as described above. explain. 12 is a block diagram showing an outline of the light source device 220 of this embodiment, and FIG. 13 is an explanatory diagram for explaining the operation of the light source device 220.

  The light source device 220 includes a rotation display control unit 222 that controls blinking of the first light projecting units 171 to 178. The rotation display control unit 222 is provided on the effect control board, and information display control according to the game development situation is performed based on a command signal from the main control board.

As shown in FIG. 13, the first light projecting units 171 to 178 in the light source device 220 are provided at predetermined angular pitches in the circumferential direction along each of the first row L ₁ to the eighth row L ₈ . The light sources 223, 223, 223, etc., and each light source 223 is composed of a light emitting element such as a single color or full color LED. For example, the first light projecting portion 171 is composed of multiple light sources 223,223,223 ... arranged at angular pitch dp on concentric circles of radius r _1.

In this case, first to the light receiving portion 141i~148i eighth row L ₁ ~L ₈ provided on the first substrate 121, a light source arranged on each column of each corresponding L ₁ ~L ₈ 223, 223 , 223... Sequentially pass through the angular positions p ₁ , p ₂ , p ₃ . Here, the angular pitch dp of p ₁ , p ₂ , p ₃ ... Can be set as appropriate. For example, it corresponds to the minute time dt at times t ₁ , t ₂ , t ₃ ... In the light source device 210 of the first embodiment. If the angle pitch is used, the same information display as that of the light source device 210 can be performed.

On the other hand, in the light source device 220 of the present embodiment, the rotation display control unit 222 does not need to perform switching control of blinking of the light sources 223, 223,. That is, in the light source device 220, the light receiving units 141i to 148i in the first to eighth rows are rotated above the corresponding light sources 223, 223, 223,. Move to trace in the order of p ₁ , p ₂ , p ₃ . At this time, if any one of the light sources (for example, a light source at an arbitrary position is 223x) is lit, the emitted light is incident on the light receiving unit only while moving above the lit light source (223x). Then, the light emitting part shines brightly, and when it passes over the light source (223x), the emitted light is not incident on the light receiving part, and the light emission is extinguished. Therefore, if the rotation display control part 222 projects the matrix pattern of the information which it is going to display on the rotation surrounding surface S on the 1st light projection parts 171-178 as it is, and light the light sources 223,223,223, ... Without performing high-speed timing control according to the rotation angle position of the rotation display member 120, a matrix of 8 rows × 8 columns can be formed on the rotation circumferential surface.

For example, when the number “7” is displayed in the same manner as described above, as shown in FIG. 13A, _eight angular positions p _{1 to} p ₈ of the first light projecting portion 171 in the first row L ₁ are displayed. The light source 223 is turned on, the two light sources 223 at the angular positions p ₁ and p ₈ are turned on for the first light projecting portions 172 and 173 in the second row L ₂ and the third row L ₃ , and the first light in the fourth row L ₄ is turned on. By turning on the light source 223 at the angular position p _{7 for} the light projecting unit 174 and then turning on the light source 223 at each corresponding row × angular position in the same manner, the numeral “7” as shown in FIG. Can be displayed on the rotating circumferential surface S. The same applies to information such as other numbers, characters, and figures.

  As described above, in the light source device 220 of the present embodiment, it is not necessary to convert information to be displayed on the rotating circumferential surface S into function information including the time axis, and the first light projecting unit 1: 1 as it is. What is necessary is just to project to 171-178. The same applies to dynamic changes in characters and graphics, and can be easily performed with a simple control program. For this reason, according to the light source device 220 of this embodiment, in addition to the fact that an angle detector is unnecessary and each light source 223 can use a relatively inexpensive LED, the rotation display control unit 222 is simplified. In addition, a rotary display device that can display spatially floating information in various display modes can be configured at low cost.

  As described above, according to the rotary display device 100 of the present invention, the light source device 160 (161, 162) is fixedly held on the main body side of the rotary display device 100, and the light emitted from the light source device is guided to the light guide member 140. , 150 are guided to the light emitting part of the rotary display member 120 and information is displayed on the rotary peripheral surface S. For this reason, it is only necessary to provide only the light guide members 140 and 150 on the rotation display member side, and it is not necessary to provide electronic components such as LEDs and control elements. Therefore, the structure of the rotation display member can be simplified and the rotation display device can be configured in a small size. Further, since the electronic component is fixedly disposed on the main body side, damage to the component due to the high-speed rotation of the electronic component can be prevented and long-term reliability can be improved. Furthermore, since it is not necessary to transmit a control signal from the main body side to the rotating body rotating at high speed, the configuration of the entire rotating display device can be simplified, and the rotating display device can be produced at low cost.

  In addition, by arranging the first light source device 161 and the second light source device 162 so as to face each other with the rotation display member 120 interposed therebetween, characters and graphics are displayed on the rotation circumferential surface S of the rotation display member 120 in different colors. It is possible to display different information overlappingly, such as displaying images that overlap with each other on the rotating peripheral surface and displaying images where different figures appear and collide from the left and right on the rotating peripheral surface, making it easy to display complicated information Can be realized.

  Therefore, according to the present invention, it is possible to produce a rotary display device capable of displaying spatially floating information with a simple structure at low cost and to provide a rotary display device with improved long-term reliability. Can do.
