Description

  The present invention relates to a configuration of a slot machine in which a backlight light source for lower panel illumination is also used for medal tray illumination.

  Among gaming machines including pachinko machines and slot machines, pachinko machines are installed in pachinko halls with relatively bright lighting so that the behavior of pachinko balls on the game board surface can be easily seen by the player. However, in the case of slot machines, there are cases where the player's consciousness is concentrated on the reel rotation, etc., or in a pachislot hall or pachislot island where room lighting is dimmed to create a casino atmosphere. Many are seen.

  However, when the periphery of the slot machine is dimmed in this way, it is difficult for the player himself to visually recognize game medals and the like in a tray provided at the bottom of the front door of the slot machine. Since it is located further below the illuminated lower panel, there is a problem that it becomes backlit and difficult to see.

  For this reason, in the conventional slot machine, as shown in Patent Document 1 below, a part of the illumination light of a fluorescent lamp or a cold cathode tube installed as a backlight light source for the lower panel is transferred to the panel holding frame of the lower panel. A structure that illuminates the saucer by leaking downward through a light guide provided through the lower part has been proposed and has already been put into practical use in some models.

  However, in the tray lighting device having the above-described conventional structure, a slit for attaching the light guide plate is provided along the longitudinal direction in the lower part of the panel holding frame, and the light guide plate is inserted into the slit and the light guide plate is illegally removed. In order to prevent foreign matter from being inserted through the slit, it is necessary to fix the light guide plate to the panel holding frame with bolts, which increases the number of steps for assembling the lower panel. In addition, the conventional light guide plate has only a function of irradiating a part of the illumination light of the backlight device for the lower panel to the tray, so that there is a problem in terms of device cost.

  The present invention attaches a display sticker printed with case management information such as certificate stamps and game-related information such as a payout table to a display plate made of a transparent material, which can be attached to the lower panel with one touch. The purpose is to overcome the conventional problems by using the display plate as a light guide plate for receiving tray illumination.

Open a slit-shaped opening on the surface from the outer peripheral surface of the panel holding frame to the space behind the lower panel , and attach a display sticker to the front or back surface excluding the surface facing the slit- shaped opening through the slit-shaped opening A plate-like display plate made of a transparent material is inserted and fixed by a retaining mechanism provided inside the slit-like opening.

  In addition, the lower panel here refers to a panel in which a motif or character of a gaming machine is printed in a design, and other than that configured by printing on the back surface of a transparent panel having a predetermined thickness. In addition, this concept includes a combination of a sheet having a pattern printed on a transparent film and a transparent panel having a predetermined thickness.

  According to a second aspect of the present invention, the lower panel includes a front panel made of a transparent plate having a predetermined thickness held by a panel holding frame, and a model on the front or back of the transparent sheet attached to the back of the front panel. A transparent back panel comprising a display sheet on which information or the like has been printed, and an outer periphery fixed to the panel holding frame behind the display sheet so as to sandwich the display sheet with the transparent panel And a gap for accommodating a display plate inserted from a slit-like opening of the panel holding frame is formed between the lower panel and the back panel.

  4. The display plate according to claim 3, wherein the display plate is divided into a plurality of parts along the width direction of the lower panel, and each of the display plates is individually inserted into a plurality of slit-like openings provided at intervals in the panel holding frame. And fixed by means of retaining means provided for each slit-like opening. However, the display plate retaining means provided for each slit-shaped opening is formed by, for example, integrally forming a return-preventing claw on the display plate itself and engaging it with a locking portion provided on the slot-shaped opening side. These may be either prevented from coming off or provided on a member that forms a slit-like opening.

  The invention according to claim 4 is characterized in that a sticker displaying management information such as a certificate or a sticker printed with game related information such as a payout table is applied as the display sticker.

In the slot machine according to claim 5, a lower panel is attached to the lower half of the front face of the front door attached to the opening on the front face of the housing through a panel holding frame, In a slot machine in which a backlight illumination device is disposed on the front surface of the front door and a tray for game medals is disposed at a position below the lower panel, at least a surface of the outer periphery of the panel holding frame that faces the top surface of the tray. A plate made of a transparent material that forms a window portion through which the backlight illumination of the lower panel can be transmitted, and a display seal is pasted on the front surface or the back surface of the lower panel excluding the surface facing the window portion. The display plate is arranged, and the display plate is fixed to the back surface of the lower panel through the plate holding means.

  According to a sixth aspect of the present invention, the lower panel includes a front panel made of a transparent plate having a predetermined thickness held by a panel holding frame, and a model attached to the front or back of the transparent sheet attached to the back of the transparent panel. A transparent display with an outer periphery fixed to the panel holding frame so that the information display sheet is sandwiched between the information display sheet and the transparent panel further behind the information display sheet. A rear panel is arranged, and plate holding means is provided on the rear panel.

  In the invention according to claim 7, the display plate is divided into a plurality of parts along the width direction of the lower panel, and each of the display plates is individually fixed by a plurality of sheet holding means formed on the back panel. It is characterized by.

  In the invention according to claim 8, a part of the information display related to the model information printed on the sticker on which the display sticker displays management information such as a certificate, the game-related information such as a payout table, or the lower panel is printed. It is characterized by being a sealed seal.

  According to the invention described in claim 1, since it is possible to fix a display plate to which a display sticker such as a certificate or a dividend table can be attached to the lower panel, the display sticker is attached to the lower panel. This can be implemented immediately before the slot machine is shipped from the factory, making the product management of the slot machine much easier, and the display plate itself guides part of the backlight illumination light for the lower panel to the top surface of the medal tray. Since the upper part of the tray and the ashtray provided adjacent to the tray can be illuminated brightly, even when the slot machine is installed in a dim hall, the player can easily see the game medals in the tray. . In addition, since the display plate has the two effects of the display sticker posting means and the tray illumination means, there is no need to provide a light guide plate or illumination device dedicated to the tray illumination, which is advantageous in terms of cost effectiveness. In addition, the display plate can be inserted into the slit-shaped opening provided in the panel frame of the lower panel by the action of the retaining mechanism, without removing the lower panel or the panel holding frame from the front door of the slot machine, or with tools, etc. Since it can be fixed with a single touch without using, there is a specific effect such as an extremely efficient assembly operation.

  Incidentally, the lower panel of the slot machine has a structure that can be removed from the front of the front door without using a screwdriver or other tool for maintenance work of the backlight illumination device after installation of the hall. Thus, it is disadvantageous to have a structure that can be easily removed. However, recently, an increasing number of manufacturers are adopting maintenance-free illumination means such as LED elements as the light source for backlight illumination, so it is technically possible to have a structure in which the lower panel cannot be easily removed. If the present invention is applied in such a case, it is expected that the security of the gaming machine can be further improved without impairing the ease of attaching the display seal and the ease of attaching the light guide plate.

  According to the second aspect of the present invention, since the gap for accommodating the display plate is formed between the lower panel and the back panel, the display plate should be removed from the slit-like opening by any chance. Even if this occurs, there is an effect that an unauthorized tool can be prevented from being inserted into the front door through the slit-like opening due to the presence of the back panel.

  According to the third aspect of the present invention, since the display plate is divided into a plurality along the longitudinal direction of the tray, it is possible to individually attach a plurality of types of display seals, and to attach each display plate. There is a merit that product management becomes easy because there is no hindrance to product shipment even if there is a large deviation. In addition, since a plurality of display plates are used, if the display plates are molded from transparent materials having different colors, the tray can be partially illuminated with different colors.

  According to the invention of claim 4, when the display sticker is a product management sticker such as a certificate paper, the display sticker with the sticker attached can be stored separately from the lower panel, and the sticking of the sticker fails. Even in this case, it is not necessary to replace the entire lower panel, and the yield is improved. Further, when the display sticker is a sticker indicating game-related information such as a payout table, the lower panel can be shared by a plurality of models by preparing a plurality of types of display stickers.

  Furthermore, according to the fifth aspect of the present invention, the display plate can be fixed to the back surface of the lower panel via the plate holding means, and is opposed to the upper surface of the display plate and the tray out of the outer periphery of the panel holding frame. Since the window that allows the backlight illumination of the lower panel to pass through is formed on the surface to be opened and the opening is not formed on the outer periphery of the panel holding frame, the display plate is external unless the lower panel is removed from the front of the front door. There is no fear that the tool will be removed from the door, and there is an effect that the risk of inserting an unauthorized tool from the opening into the front door is reduced.

  According to the invention of claim 6, since the display seal is held by the plate holding means of the back panel attached to the back of the lower panel and is visible from the front of the slot machine through the lower panel, Even if the design of the lower panel is changed up to now, it becomes possible to share the back panel and the display plate, so that an increase in product cost can be suppressed. It is also possible to share the back panel and display plate with a plurality of models.

  According to the seventh aspect of the invention, since the display plate is divided into a plurality along the longitudinal direction of the saucer, it is possible to attach a plurality of types of display seals individually, and to attach each display plate. There is a merit that product management becomes easy because there is no hindrance to product shipment even if there is a large deviation. In addition, since a plurality of display plates are used, if the display plates are molded from transparent materials of different colors, the lower panel can be backlit with partially different colors, and the medal tray can be partially Since it is possible to illuminate with different colors, a decorative effect can be expected.

  According to the invention of claim 8, in particular, a sticker on which a part of information display related to the model information printed on the lower panel is printed as a display sticker, that is, a character or model that is a part of the design of the lower panel. If you use a partial seal printed with motifs or nicknames of models other than the name, and form a transparent part on the lower panel where the partial seal can be seen, the panel design can be changed significantly by changing the partial seal. Yes, it is possible to support multiple models with one type of lower panel.
