Description

  The present invention relates to a display device for pachinko halls.

  Conventionally, a method of arranging a fluorescent tube on the back surface of a liquid crystal display is generally used for a display of an OA device such as a word processor. However, recently, a surface light source device called an edge light system has been developed for thinning (see Patent Document 1).

This surface light source device includes a lamp tube as a light source and a light guide panel, but the light source is disposed not at the back of the light guide panel but at one end edge. In addition, the light guide panel is configured by overlapping a diffusion sheet and an opaque reflection sheet on both sides of a transparent acrylic plate. When light from the lamp tube enters from one end edge of the light guide panel, the light is It spreads within the acrylic plate, is reflected by the reflection sheet, and is emitted from the entire side surface through the diffusion sheet.

  However, in order to apply the above structure as a pachinko hall display device as it is, further contrivance is required.

  The present invention has been completed based on the above circumstances, and an object thereof is to provide a suitable display device for a pachinko hall.

  As means for achieving the above object, the invention of claim 1 is directed to a light source incorporated in a curtain plate, a guide member attached to the curtain plate at a position corresponding to the light source, and the guide member. A light guide display unit that is detachable and allows light from the light source to enter from the edge of the light source when it is attached to the guide member and to be transmitted from both side surfaces thereof, and the light guide display unit assembled in the guide member It is characterized in that it comprises a switch for turning on and off the light source by inserting and removing.

<Invention of Claim 1>
According to the display device of the present invention, the switch can be turned on / off by inserting / removing the light guide display portion, and the light source can be turned on / off.

Hereinafter, an embodiment in which the surface light source device of the present invention is applied to a display device for notifying a big hit state in a pachinko hall will be described with reference to FIGS.
As shown in FIG. 1, the surface light source device of the present invention includes a light source unit 1 and a light guide display unit 2 that is detachably assembled to the light source unit 1.

  First, the light source unit 1 will be described. As shown in FIG. 2, the curtain plate 3 disposed above the pachinko machine has a vertically long opening 3a corresponding to each pachinko machine. A lamp case 4 is attached with screws or the like so as to cover the opening 3a from the side. A translucent plate 5 having translucency is fitted and attached to the surface of the lamp case 4 facing the opening 3a. Further, three lamps 6 are accommodated in the lamp case 4 in a state where the lamps 6 are arranged in the vertical direction at a predetermined interval, and light from each lamp 6 is irradiated forward through the translucent plate 5. . The lamp 6 is not limited to an incandescent lamp, and a fluorescent tube, a flash lamp, or the like may be used. In particular, depending on the thickness of the lamp case 4, there is a case where the lamp case 4 cannot be mounted unless a hole is made in the curtain plate. In such a case, it is desired to reduce the thickness by using a fluorescent tube.

  A guide member 7 that is a component of the light source unit 1 is provided at a position corresponding to each opening 3 a on the front surface of the curtain plate 3. The guide member 7 is for guiding the insertion of the light guide display unit 2 to be described later and holding the display unit 2 together, and is formed in a C-shaped cross section that opens to the front side and the upper side. Is closed by a bottom plate 9. Further, a limit switch 10 is provided at the center of the upper surface of the bottom plate 9, and the light guide display unit 2 is set in the guide member 7 so that it is turned on by the lower end surface of the light guide display unit 2. It is. This limit switch 10 is incorporated in the lighting circuit (not shown) of each lamp 6 described above, and each lamp 6 is turned on / off by turning on / off the limit switch 10. However, it is also possible to turn on / off manually. Besides, the light from the light emitting diode is blocked by the light guide display unit 2 using a photodiode and a light emitting diode, and the lamp 6 is turned on. The thing of a structure, the thing of the structure etc. which are made into a conduction | electrical_connection state by the part of the light guide display part 2 contacting a part by the side of the light source part 1, and the lamp | ramp 6 lights up may be sufficient.

  Next, the light guide display unit 2 will be described with reference to FIGS. 3 and 4. The light guide display unit 2 includes a light guide panel 8 and a locking tool 11 attached to one end edge side of the light guide panel 8. This locking tool 11 has a pair of flange pieces 11 a at the side edge of the portion that is press-fitted into one edge of the light guide panel 8, and the light guide display section 2 by inserting both flange pieces 11 a into the guide member 7. Is held freely.

  The light guide panel 8 is formed in a rectangular shape in the figure by bonding two transparent acrylic light guide plates 12, and is approximately the same size as the light guide plate 12 between the two light guide plates 12. A reflection sheet 13 made of a non-light-transmitting material is sandwiched. However, in this example, the two light guide plates 12 are bonded to each other by applying an adhesive, but may be fixed by being clamped to the periphery by an appropriate clamp. Moreover, you may make it shape | mold in the state which inserted the reflective sheet.

  A translucent diffusion sheet 14 for emitting light in both directions while scattering light is applied to both outer surfaces of the light guide panel 8 formed by bonding the two light guide plates 12 to each other. Each is pasted together. Further, the front side surface of each diffusion sheet 14 is marked with a “big hit” character. In this example, several display panels with different display contents are prepared (for example, with a “lucky stand” display as shown in FIG. 6), and are appropriately selected and used depending on the situation. .

  Further, in the light guide panel 8 formed by bonding the two light guide plates 12, the reflection sheet 13 is also attached to other peripheral edges except for the edge on the side facing the light source unit 1, so that light does not leak from these. It has become. Furthermore, as shown in FIG. 5, the surface of each light guide plate 12 on which the reflection sheet 13 is bonded is provided with a speckle pattern 15 for diffusing light to the opposite surface by silk printing. At the same time, the spot pattern 15 is roughly arranged on the side close to the light source unit 1 and is arranged so as to become denser as it goes away, thereby making it possible to emit light uniformly over the entire area on the side of each diffusion sheet 14. .

  Next, the operation of this embodiment will be described. When a specific pachinko machine is in a so-called “big hit” state, an employee attaches the light guide display unit 2 to the guide member 7 in order to notify the customer in the store. First, the flange piece 11 a of the locking tool 11 is inserted from above the guide member 7. When the bottom plate 9 is inserted, the limit switch 10 is pushed by the lower end of the locking tool 11, and each lamp 6 is lit by a lighting circuit (not shown). Then, the light from each lamp 6 divides and spreads in the light guide plate 12 from the side edge of each light guide plate 12 and is reflected by each reflection sheet 13. Then, the light is emitted from both sides of the light guide panel 8 to both sides (in the direction of the arrow in FIG. 6) via the diffusion sheet 14. As a result, the letters “big hit” appear on both side surfaces of the light guide panel 8, and the big hit state can be visually recognized from both sides of the light guide panel 8. In other words, in this example, the character is not illuminated from the front or from the side, but light is emitted from the background of the character, so that the entire outline of the character can be shined, so that it has excellent visibility It becomes.

  Further, when the big hit state is finished, the light guide panel 8 is removed from the guide member 7. To do this, the light guide panel 8 is moved upward and the locking tool 11 is pulled out from the guide member 7. .

  Furthermore, the open base that experienced a big hit that day was replaced with a light guide panel 8 with “lucky stand” indications on both sides. In this case, the light from each lamp 6 The light is divided and spreads in the light guide plate 12 and light is emitted from both side surfaces, and the characters can be visually recognized from both sides of the light guide panel 8.

  That is, in this embodiment, although the light source is a surface light source and the two light guide plates 12 are bonded to each other with the reflection sheet 13 interposed therebetween, the light from each lamp 6 spreads in each light guide plate 12 and spreads. Since the light is emitted from the surface, the characters can be visually recognized from both sides of the light guide panel 8, and the practical value is increased. Moreover, since the other side surface does not show through from one side surface, the characters arranged on both side surfaces do not appear to overlap each other, and the character content can be reliably recognized even from a distance.

In addition, this invention is not limited to the said Example, For example, it can deform | transform and implement as follows, These embodiments also belong to the technical scope of this invention.
(1) In the present embodiment, the characters and the like are described on the diffusion sheet 14, but the configurations described on both surfaces of the reflection sheet sandwiched between the respective light guide plates may be used.
(2) In the present embodiment, the light source unit 1 and the light guide display unit 2 are configured to be detachable, but may be configured to be fixed.
(3) In this embodiment, the characters described in each diffusion sheet 14 have the same contents, but may have different contents.
(4) Although this example shows the case where it is applied to a pachinko hall, for example, it is used for a display billboard or a signboard that displays “open” or “today's business has ended” in restaurants, etc. In particular, the present invention has a great practical value in an aspect in which thinness is required and display contents must be notified to many people.

  (5) In this example, the reflection sheet 13 is used as the non-translucent layer, but any material may be used as long as it does not have translucency.

(6) In this example, the change in the display content is accompanied by a change in the entire light guide display unit 2, but several reflection sheets with different contents are prepared, Instead of replacement, it is also possible to replace the reflective sheet alone. In this case, a groove may be formed in one light guide plate along the plane direction so that the reflection sheet can be inserted and removed. Further, the display position of the characters may be described here by placing a transparent sheet on the front side of the sheet instead of the reflective sheet. In such a case, the transparent sheet may be replaced as a single unit, and in this case, the transparent sheet may be fixed in a state of being sandwiched by the clamping tool as described above instead of being inserted into the groove. Further, a color sheet may be used as the transparent sheet, and characters may be provided directly or by stamping, whereby simple color display is achieved.
(7) Although the light source is housed in the lamp case 4 in this example, it is also possible to house the light source in the locking tool 11. In such a case, a connector may be formed on the locking tool 11 itself and fitted to the connector on the curtain plate side so as to achieve electrical connection. In addition, the present invention can be implemented with various modifications without departing from the scope of the invention.
