Description

  The present invention relates to a display device in which an image display device such as a liquid crystal display device or electroluminescence is arranged on an outer peripheral surface of a rotating body rotated by predetermined power.

Conventionally, a plurality of types of symbols are displayed side by side on the outer circumferential surface of a substantially cylindrical rotating body (also referred to as a “reel”) (for example, a tape displaying a pattern is pasted on the outer circumferential surface of the rotating body), There has been known a display device that changes a visible symbol before and after rotation by rotating the rotating body.
However, only by displaying a plurality of symbols on the rotating body, only the number of symbols displayed can be changed. Therefore, a transparent liquid crystal display device (in which the rear rotating body can be seen) is arranged in front of the rotating body, and a combination of a change in design due to the rotation of the rotating body and an image display by the liquid crystal display device is known. (For example, refer to Patent Document 1).
JP 2007-268173 A

  However, in the technique of the above-mentioned Patent Document 1, if an image is displayed by the liquid crystal display device at the same time while the rotating body is rotating, the visibility of the symbol during the rotation of the rotating body is lowered. Therefore, there is a problem that the image display by the liquid crystal display device is limited to being performed only while the rotating body is stopped. For this reason, there is a problem that the moving display of the symbols while the rotating body is rotating and the image display by the liquid crystal display device are performed independently and are not integrated displays.

  Even if the transparent liquid crystal display device is arranged in front of the rotating body, the design of the rotating body positioned behind the rotating liquid crystal display device is visible. However, since the transparent liquid crystal display device is not a completely transparent body, there is a problem that the visibility of the design of the rotating body is inevitably lowered.

  Therefore, the problem to be solved by the present invention is to display various symbols without reducing the visibility of an image when displaying an image using both a rotating body and an image display device. .

The present invention solves the above-described problems by the following means.
The invention according to claim 1, which is one of the present invention, has a rotating body whose outer shape is formed in a substantially cylindrical shape or a substantially polygonal shape, and a plurality of the rotating bodies arranged in a circumferential direction on the outer peripheral surface of the rotating body, And an image display device including a liquid crystal display device, electroluminescence, or a dot display device in which a plurality of light emitting elements are arranged vertically and horizontally.
According to a second aspect of the present invention, in the display device according to the first aspect, the rotating body is formed in a substantially hollow columnar shape or a substantially hollow polygonal shape, and is rotatable about a predetermined member. The image display device is the liquid crystal display device, and a part of the rotating body on which the liquid crystal display device is disposed is an opening, or is formed to be transparent or translucent, The backlight of the liquid crystal display device is disposed on the inner peripheral side of the rotating body and is fixed to a support member.
Furthermore, the invention according to claim 4 is the display device according to claim 1, wherein the image display device is formed in a flat plate shape and has flexibility, and the image display device is the rotating body. When attached to the outer peripheral surface, the lower surface of the image display device is attached with substantially the same curvature as the outer peripheral surface of the rotating body.

(Function)
In the said invention, the symbol displayed on the outer peripheral surface of a rotary body is displayed by image display apparatuses, such as a liquid crystal display device. For this reason, the design of the rotating body can be variously changed. When a liquid crystal display device is used as the image display device (claim 2), the backlight of the liquid crystal display device can be disposed in the rotating body. Furthermore, when the image display device is flexible, it can be provided on the rotating body with substantially the same curvature as the outer periphery of the rotating body.

  According to the said invention, when displaying an image using both a rotary body and an image display apparatus, various symbol displays can be performed, without reducing the visibility of an image.

Embodiments of the present invention will be described below with reference to the drawings. In the present invention, “image” is used to include both a still image and a moving image (video).
(First embodiment)
FIGS. 1A and 1B are diagrams illustrating a configuration of a part of the display device 10 according to the first embodiment. FIG. 1A is an external view, and FIG. 1B is a front view illustrating the inside of a rotating body 21.
In FIG. 1, the display device 10 includes a rotating body 21 and a plurality of image display devices 22.

In this embodiment, the rotating body 21 is made of a resin material and is formed in a substantially hollow cylindrical shape. An air cylinder-shaped rotating shaft portion 21 a is formed at the center of the rotating body 21.
In addition, the image display device 22 is arranged on the outer peripheral surface of the rotating body 21 side by side at equal intervals in the circumferential direction. In the present embodiment, 10 image display devices 22 are arranged at equal intervals, so that the outer circumference of the rotating body 21 is made one round. In the present embodiment, the image display device 22 is a transmissive liquid crystal display device (full color TFT).

Furthermore, the motor 23 is a stepping motor in this embodiment, and is fixed to the fixed base 24. The rotating body 21 is rotatably supported by the motor 23 by connecting the rotating shaft 23 a of the motor 23 and the rotating shaft portion 21 a of the rotating body 21. The rotating body 21 does not interfere with the motor 23 and the fixed base 24 even if it rotates.
Further, an image display control board 25 is fixed on the inner peripheral surface side of the rotating body 21. The image display control board 25 is electrically connected to all the image display devices 22.

FIG. 2 is an exploded perspective view showing the rotating body 21, the image display device 22, and the like. As shown in FIG. 2, a substantially quadrangular opening 21 b is formed in a portion where the image display device 22 is attached on the outer peripheral surface of the rotating body 21.
In the present embodiment, the image display device 22 has a diagonal of about 2 to 3 inches, and the opening 21b has a slightly smaller size (the image display device 22 is placed on the opening 21b). In some cases, the image display device 22 and a part of the rotating body 21 are in contact with each other so that they can be bonded together.
The opening 21b may be formed by cutting after the rotary body 21 is formed. Alternatively, the opening 21b may be formed by connecting both ends of a member formed in a substantially ladder shape and having a substantially cylindrical shape.

  Further, in the image display device 22, not all components are arranged on the outer peripheral surface of the rotating body 21, but a portion of the image display device 22 excluding the backlight 22 a, that is, a polarizing filter, a glass substrate, and a transparent The electrode, alignment film, liquid crystal, spacer, and color filter are disposed on the outer peripheral surface of the rotating body 21, and only the backlight 22 a is disposed inside the rotating body 21.

In the example of FIG. 2, in order to illuminate all the image display devices 22, the backlight 22a is formed in a cylindrical shape.
Although not shown, the backlight 22 a is fixed to the fixed base 24 shown in FIG. 1 and is formed so as not to rotate even when the rotating body 21 rotates. Thus, even if the backlight 22a is arranged on the inner peripheral side of the rotating body 21, light can be incident on the polarizing filter of the image display device 22 through the opening 21b.
Note that the opening 21b is not necessary if the light of the backlight 22a can be transmitted from the inner peripheral side to the outer peripheral side of the rotating body 21 by forming the rotating body 21 from a transparent or translucent material.

FIG. 3 is a side sectional view showing the shape of the backlight 22a. In FIG. 3, (a) shows the thing of FIG. As shown in FIG. 3 (a), that is, FIG. 2, the backlight 22a may be formed in a substantially cylindrical shape, but as shown in FIG. 3 (b), the backlight 22a may be formed only in a part. .
In the example of FIG. 3B, a portion including the rotating body 21 and the image display device 22 in the display device 10 is housed in the housing 26. Note that the motor 23 and the fixing base 24 shown in FIG.

  3B, the housing 26 has an opening surface 26a on the front surface (left side in FIG. 3B). Then, the three image display devices 22 on the rotating body 21 are formed so as to be exposed from the opening 26a (visible from the front surface of the housing 26). In this case, it is not necessary for the backlight 22a to illuminate all the image display devices 22, and it is sufficient if the three image display devices 22 that are visible to the outside can be illuminated. For this reason, the backlight 22a shown in FIG. 3B is formed in a substantially arc shape, and is formed in a shape that illuminates only the three image display devices 22.

FIG. 4 is a front cross-sectional view illustrating the arrangement of the power supply, the substrate, and the like of the display device 10, and FIG. 5 is a block diagram of the display device 10.
In FIG. 5, the motor 23 is electrically connected to a drive control board 29, and rotation and stop are controlled by the drive control board 29. Power is supplied to the drive control board 29 by a power supply 30. The power supply 30 also supplies power to the motor 23.

Further, power is supplied from the power supply 30 to the backlight 22a.
On the other hand, the image display device 22 is electrically connected to the image display control board 25, and the image display is controlled by the image display control board 25.

  Here, it is necessary to supply power to the image display control board 25 and the image display apparatus 22, but the image display control board 25 and the image display apparatus 22 rotate with the rotation of the rotating body 21. When power is supplied by connecting to the power source, the electric wire is twisted. Therefore, in the present embodiment, the battery 27 is disposed at the center of rotation of the rotating body 21 (see FIG. 4). Further, a movable power supply 28 that can be brought into contact / non-contact with the battery 27 is provided. While the rotating body 21 is stopped, the battery 27 and the power source 28 are electrically connected, and the battery 27 is charged by the power source 28. On the other hand, while the rotating body 21 is rotating, the power source 28 is separated from the battery 27 and is not in contact.

If comprised as mentioned above, even during the rotation of the rotating body 21, the electric power can be supplied to the image display control board 25 and the image display control board 25 via the image display control board 25 without twisting the electric wire. And a predetermined image can be displayed.
If the contact surface between the battery 27 and the power supply 28 has wear resistance, both may be always connected (the power supply 28 is not retracted during rotation).

  In the present embodiment, the backlight 22a is fixed. For example, the backlight 22a is disposed integrally with the rotating body 21 along the inner peripheral surface of the rotating body 21, and the backlight 22a is rotated along with the rotation of the rotating body 21. In the case where 22a is also formed to rotate at the same time, the battery 27 and the backlight 22a may be electrically connected via the image display control board 25, and the power of the backlight 22a may be supplied by the battery 27.

  Further, as shown in FIG. 5, the position of the rotating body 21 is detected by a position detection sensor 31, and the drive control board 29 drives and controls the motor 23 based on the detection result. Although not shown, a detector is formed on the rotator 21, and the detector is detected by the position detection sensor 31 every time the rotator 21 makes one rotation. Then, the drive control board 29 can know the current position of the rotating body 21 by counting the detection result of the position detection sensor 31 and the number of steps of the motor 23 from the time when the position detection sensor 31 is detected. . Thereby, the drive control board 29 can drive the motor 23 to stop the rotating body 21 at a desired position.

Next, an example of image display by the image display device 22 will be described.
The image display control board 25 stores image data for image display in a ROM or the like. For example, at first, by default, a specific symbol is displayed as an image for each image display device 22, and when the condition for changing the symbol is satisfied, the image data is read out, and at least one image display device 22 is displayed. The image display is controlled to change.

As a change of the image display,
(1) Turn on, blink, and turn off the symbol (including the background, the same applies hereinafter).
(2) Change the color of the design.
(3) Change the size of the symbol.
(4) Change to a different symbol instantaneously or after turning off or lighting, or display the same symbol after turning off or lighting.
(5) Move the design (video display).

  (6) One image display device 22 and the other one image display device 22 display a series or related images in conjunction with each other. For example, in the case where one rotating body 21 is provided, as shown in FIG. 3B, when three image display devices 22 that are continuous in the vertical direction are arranged so that they can be seen, these three image display devices 22 , Display a series or related images in conjunction. Alternatively, when a plurality of rotating bodies 21 are arranged in parallel (see FIG. 11 described later), at least one image display device 22 on one rotating body 21 and at least one on another rotating body 21 are arranged. A series of or related images are displayed in conjunction with the image display device 22.

(7) By displaying the same symbol on all the image display devices 22 of one rotating body 21, it is displayed so that only one symbol can be seen even during rotation.
(8) While one rotating body 21 is rotating, a graphic that changes little by little is displayed on each image display device 22 to give a viewer a sense of moving images.

  FIG. 6 is a diagram illustrating an arrangement example of the display device 10. For example, as illustrated in FIG. 6, the display device 10 is arranged so that the rotation axis of the rotating body 21 is up and down. The rotating body 21 is supported by a rotating shaft 32 so as not to move in the vertical direction and to be rotatable. Then, the rotating body 21 is rotated clockwise as viewed from above. An image such as a comment can be displayed using this. In FIG. 6, it is assumed that ten image display devices 22 are provided.

  For example, when the display device 10 is installed in a supermarket, each character of the image display device 22, for example, “ki” “yo” “u” “ha” “o” “ “Meat” “No” “Special” “Sell” “Day” “De” “Su” “.” Are displayed as images. Here, when the number of the image display devices 22 is 10, images from “ki” to “day” can be displayed on different image display devices 22. Then, “ki” is changed to “de” until the image display device 22 displaying the first “ki” makes one rotation and returns to the front (for example, when it is arranged at the back position). To control. Similarly, control is performed so that the second “「 ”is changed to“ su ”. In this way, it is possible to display a comment or the like exceeding 10 characters using the ten image display devices 22.

In the case of FIG. 6, the rotating body 21 may be rotated by the motor 23, but other power can be used. For example, if the display device 10 is installed near the air conditioner so that the wind from the air conditioner always hits the rotating body 21, the rotating body 21 can be continuously rotated only by the wind without driving force.
Further, when one rotating body 21 is provided as shown in FIG. 6, the motor 23 may be arranged inside the rotating body 21 (as shown in FIG. 1B), Alternatively, it may be arranged outside the rotating body 21.

(Second Embodiment)
FIG. 7 is a diagram showing a second embodiment when the image display device 22 is attached (pasted) to the rotating body 21. In the first embodiment, as shown in FIG. 2, each individual image display device 22 is attached to the rotating body 21, but in the case of FIG. 7, a plurality of image display devices 22 to be attached are preliminarily set to 1. A belt-like sheet 33 is provided and is attached to the outer periphery of the rotating body 21. If the image display device 22 is attached in this way, it can be easily attached to the rotating body 21 and the assembly time can be reduced.
In FIG. 7, the number of image display devices 22 is seven, but the number is not limited to this. In FIG. 7, unlike FIG. 2, the opening 21b is omitted.

(Third embodiment)
8 and 9 are diagrams showing wiring of the image display device 22 when the image display device 22 is formed on one sheet 33 as shown in FIG.
First, in FIG. 8A, the electric wire 34 is drawn out of the sheet 33 from each image display device 22 and is bundled into one electric wire 34 on the outer side.
Further, in FIG. 8B, the electric wires 34 are pulled out from the image display devices 22 to the back side of the sheet 33 and are formed into one bundled electric wires 34 on the back side of the sheet 33.

Further, in FIG. 9, in the case of FIG. 8A, between each image display device 22 and one bundled electric wire 34, a connector 35 (the image display device 22 side is a concave connector 35a and the electric wire 34 side is an electric wire 34 side. A convex connector 35b) is provided.
When joining the image display device 22 and the electric wire 34 may cause poor bonding, connecting all the image display devices 22 to one electric wire 34 may cause a decrease in yield. Since there is a possibility, it connects with the connector 35 like FIG. When a defect occurs, each image display device 22 can be replaced.

(Fourth embodiment)
In the above embodiments, both the image display device 22 and the image display control board 25 are attached to the rotating body 21. On the other hand, it is possible not to rotate the image display control board 25 together with the rotating body 21 by pulling out the electric wire of the image display device 22 to the outside.
FIG. 10 is a diagram showing the wiring of the electric wires in this case. First, in the case of FIG. 10A, the electric wires 34 exiting from the individual image display devices 22 are collected at the center of the rotating body 21. And the hollow cylinder part 21c is provided in the rotation center part of the rotary body 21, the electric wire 34 is passed through the inside of this hollow cylinder part 21c, and it sends out outside.

  In the case of FIG. 10B, as shown in FIGS. 8 and 9, the electric wires 34 of the individual image display devices 22 are bundled into one, and the electric wires 34 are passed through the hollow cylindrical portion 21c. , Which is sent out to the outside.

  Note that the image display device 22 is always attached to the rotating body 21 side. However, when the image display control board 25 is fixed outside the rotating body 21 (when not rotating together with the rotating body 21), the rotating body is used. The more the wire 21 rotates, the more the wire 34 connecting the image display device 22 and the image display control board 25 is twisted. In order to avoid this, for example, when the rotational speed of the rotating body 21 reaches a predetermined number, the rotating body 21 is reversely rotated to eliminate the twist. In addition, for example, forward rotation and reverse rotation may be alternately performed such that the first rotation is forward rotation, the second rotation is reverse rotation, the third rotation is forward rotation, and so on.

(Fifth embodiment)
In the fifth embodiment, the rotation of the rotating body 21 and the image display by the image display device 22 are linked to each other, and can be applied to a gaming machine, for example.
FIG. 11 is a diagram showing a gaming machine in which three display devices 10 (display devices 10A, 10B, and 10C) are arranged in parallel. A symbol is displayed on each image display device 22 of each display device 10. When the three rotating bodies 21 are rotated and stopped, when the combination of symbols stopped on the line L is a predetermined symbol combination, for example, “7”-“7”-“7” is obtained. In some cases, a profit (for example, payout of a predetermined number of medals) according to the combination of symbols is performed.
In addition, when arrange | positioning the some rotary body 21 close | similarly like FIG. 11, it is preferable to arrange | position each motor 23 inside the rotary body 21, as shown in FIG.1 (b).

FIG. 12 is a diagram illustrating a block diagram of a gaming machine according to the fifth embodiment. A subscript A is attached to each component of the display device 10A, a subscript B is attached to each component of the display device 10B, and a subscript C is attached to each component of the display device 10C.
In FIG. 12, the control board 50 is located at the highest level among the boards, and is a board that performs overall control of the entire game, and includes drive control boards 29A to 29C and image display control boards 25A to 25A of each display device 10A to 10C. It is electrically connected to 25C. Further, unlike FIG. 5, each of the backlights 22aA to 22aC is electrically connected to the image display control boards 25A to 25C, respectively.
The start button 40 and the stop buttons 41 </ b> A to 41 </ b> C are electrically connected to the control board 50.

When the player operates (turns on) the start button 40, the signal is input to the control board 50. When receiving this signal, the control board 50 transmits a command to start driving the motors 23A to 23C to all the drive control boards 29A to 29C. As a result, the drive control boards 29A to 29C drive the motors 23A to 23C, respectively, to control the rotating bodies 21 to rotate.
In addition, each drive control board | substrate 29A-29C can grasp | ascertain now the position which the rotary body 21 is in as mentioned above.

The image display control boards 25A to 25C store image data to be displayed as a default on the image display device 22, and the image display control boards 25A to 25C control the image display devices 22A to 22C. Then, control is performed to display a predetermined symbol as an image.
Further, when the start button 40 is operated, the control board 50 performs a lottery. For example, the control board 50 always generates a random number while the power is on, and extracts the random number when a signal indicating that the start button 40 has been operated is received. Based on the extracted random numbers, the combination of symbols that can be stopped and the combination of symbols that cannot be stopped are determined.

  Next, when the player operates the stop buttons 41 </ b> A to 41 </ b> C, the signal is input to the control board 50. When the control board 50 receives this signal, the control board 50 applies a motor to the drive control boards 29A to 29C corresponding to the operated stop buttons 41A to 41C (for example, the drive control board 29A when the stop button 41A is operated). A command to stop driving 23A to 23C is transmitted. Accordingly, the drive control boards 29A to 29C perform control so as to stop driving the motors 23A to 23C and stop the rotating body 21, respectively.

  Furthermore, the control board 50 transmits information related to the position where the rotating body 21 can be stopped and the position where the rotation body 21 cannot be stopped to the drive control boards 29A to 29C based on the lottery result. The drive control boards 29A to 29C determine the stop position based on the design of the image display device 22 located on the line L at the moment when the stop buttons 41A to 41C are operated, and the rotator 21 at the determined position. Stop.

  For example, when the combination of symbols “7”-“7”-“7” is not stopped as a result of the lottery, the drive control boards 29A to 29C control the motors 23A to 23C when the rotating body 21 is stopped. 7 ”is controlled so as not to stop on the line L. For example, when the stop button 41A-41C is operated at the moment when the symbol “7” passes on the line L, the image display device 22 on which the symbol “7” is displayed stops below the line L. Then, control is performed so that the image display device 22 on which a symbol other than “7” is displayed does not stop on the line L.

  On the other hand, when “7”-“7”-“7” can be stopped as a result of the lottery, the drive control boards 29A-29C control the motors 23A-23C when the rotating body 21 is stopped, Control is performed so that the symbol “7” stops on the line L. For example, it is assumed that the number of moving symbols from the moment when the stop buttons 41A to 41C are operated until the rotating body 21 stops is set within two symbols including the symbols. In this case, when the stop button 41A-41C is operated at the moment when the symbol “7” passes one line L above, the movement control is performed by one symbol at the time of stop, and the symbol “7” is displayed. The controlled image display device 22 is controlled to stop on the line L.

  In the gaming machine of the present embodiment, the control board 50 controls the rotation of the rotating body 21 (control of the drive control boards 29A to 29C) and images by the image display devices 22A to 22C including the backlights 22aA to 22aC. Display (control of the image display control boards 25A to 25C) can be performed simultaneously.

Therefore, for example, when a signal indicating that the start button 40 has been operated is input to the control board 50, the symbols of the image display devices 22 are blinked for a moment (backlights 22aA to 22aA). The power supply to 22aC can be cut off for a moment). If the result of the lottery performed by the control board 50 is a disadvantageous result for the player (for example, non-winning), the image display by the image display device 22 is not changed. When “7”-“7”-“7” can be stopped, it is possible to perform an effect of blinking or changing the design of each image display device 22 for a moment.
The above-described control may be performed every game, or may be performed only when winning as a result of lottery.

(Sixth embodiment)
FIG. 13 is a side view showing the rotating body 21 and the image display device 22 in the sixth embodiment. In the sixth embodiment, a configuration in which six flat image display devices 22 are attached to a substantially cylindrical rotating body 21 is shown.
Here, as shown in FIG. 3A, as the number of image display devices 22 attached to the rotator 21 increases, the outer peripheral shape approaches a circular shape. However, as shown in FIG. When the number of the rotating bodies 21 is small, the outer shape of the rotating body 21 is substantially hexagonal in spite of being substantially cylindrical.
Then, it can be used as the display device 10 as it is, but as shown in FIG. 13, if a substantially flat dome-shaped transparent or translucent lens 36 is mounted on each image display device 22, the outer shape is It can be approximated to a substantially cylindrical shape.

(Seventh embodiment)
FIG. 14 is a partial cross-sectional view showing the seventh embodiment. In the above embodiment, the image display device 22 is composed of a liquid crystal display device, and a polarizing filter, a glass substrate, a transparent electrode, an alignment film, a liquid crystal, a spacer, and a color filter excluding the backlight 22 a are provided on the outer peripheral surface of the rotating body 21. The backlight 22 a is arranged on the inner peripheral side of the rotating body 21. However, the present invention is not limited to this, and as shown in FIG. 14, the backlight 22 a (including the entire image display device 22) may be disposed on the outer peripheral surface of the rotating body 21. In this case, it is not necessary to arrange the backlight 22a on the inner peripheral side of the rotating body 21. Moreover, it is not necessary to form the opening part 21b in the rotary body 21, or it does not need to be transparent or translucent.

(Eighth embodiment)
FIG. 15 is a partial sectional view showing the eighth embodiment. In the above embodiment, the image display device 22 is configured from a liquid crystal display device. On the other hand, 8th Embodiment is comprised from electroluminescence (EL).
Here, examples of EL include organic EL and inorganic EL. From the viewpoint of power consumption and the like, organic EL is preferable. In addition, an active matrix type in which organic ELs are arranged in a matrix and driving means (TFT) is provided for each organic EL element is preferable.

Furthermore, a glass substrate is used as the EL base material (base). In this case, the image display device 22 has a flat plate shape and is attached to the rotating body 21 as shown in FIG.
On the other hand, an organic thin film transistor (TFT) and an organic EL element may be integrated on a plastic film so as to have flexibility (flexibility).
When formed in this way, as shown in FIG. 15, the outer peripheral surface of the rotating body 21 can be affixed to the rotating body 21 by being deformed into a curvature substantially the same as that of the rotating body 21. Even after the image display device 22 is arranged on the display 21, the outer shape is substantially cylindrical, and the image is easy to see.
Since EL is self-luminous, a backlight is not required as in the above embodiment. Further, EL is preferable as a display device because it is thinner than a liquid crystal and has a wide viewing angle.

Further, even when the image display device 22 is formed of a liquid crystal display device, the liquid crystal display device may be formed so as to be flexible and attached in the same manner as in FIG.
