Description

  The present invention relates to a light-emitting device for a gaming machine in which a light-emitting source such as an LED is disposed on one axial end of a rod-shaped light guide member.

  2. Description of the Related Art Conventionally, in a gaming machine such as a pachinko machine or a slot machine, various light emitting devices are provided for the purpose of exciting the game. As one type, for example, as described in Patent Document 1, light emitted from a light source disposed on one end in the longitudinal direction of a transparent columnar light guide is incident on the columnar light guide, A light emitting device is known that reflects light traveling through the columnar light guide in a reflective layer formed on the peripheral surface of the columnar light guide.

  However, since the light emitting device having the above-described structure is used in a state of being fixed to a gaming machine as disclosed in Patent Document 1, the player is entertained. In this case, it is difficult to exert a sufficient effect.

  Therefore, in order to entertain the player, it is conceivable to move the light emitting device having the above-described structure. Specifically, for example, it is conceivable to rotate the columnar light guide or the light source disposed on one end in the longitudinal direction around the side where the light source is disposed in the columnar light guide around one axis.

  By the way, when rotating the columnar light guide or the light source disposed at one end in the longitudinal direction around the side where the light source is disposed in the columnar light guide, for example, the longitudinal direction of the columnar light guide One end side, light source, etc. are housed in the case, and the driving force of the electric motor composed of a stepping motor, etc. is transmitted to the case via a reduction gear train as a speed reduction means, and the case itself is rotated about one axis. Thus, it is conceivable to rotate the columnar light guide or the light source disposed on one end in the longitudinal direction about one axis.

  However, when the above-described method is adopted, the case itself, and thus the entire structure of the light-emitting device, is increased in size simply by housing one end side of the columnar light guide in the longitudinal direction or the light source in the case. In addition, it may be difficult to secure a space for installing the light emitting device and a driving space.

  Here, the present invention has been made in the background as described above, and the solution is to solve the light emitting device for a gaming machine having a novel structure capable of realizing a compact overall structure. Is to provide.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  The light-emitting device for gaming machines of the present invention includes a disk-shaped base member that is rotated about its own central axis by transmitting the driving force of the electric motor, and the rotation of the base member. One feature is that the base member is provided with a rod-shaped light guide member having one end in the longitudinal direction superimposed on the base member in a state substantially orthogonal to the central axis, and the other end in the longitudinal direction extending from the outer periphery of the base member. In the light-emitting device for gaming machines of the present invention, a light-emitting source that emits light incident on the end surface on one end side in the longitudinal direction of the rod-shaped light guide member is mounted, and the mounting surface of the light-emitting source is positioned to face the end surface. And a substrate that is assembled to the base member in a state in which the rod-shaped light guide member is mounted on the other end side in the longitudinal direction of the rod-shaped light guide member. A fixing member for fixing the rod-shaped light guide member to the base member by screwing and fixing to the base member on one end side of the rod, and further covering one end side in the longitudinal direction of the rod-shaped light guide member and the substrate. It is also characterized in that it includes a cover member that is screwed to the base member and has a bottomed and covered cylindrical shape as a whole together with the base member. Furthermore, in the light emitting device for gaming machines of the present invention, the fixing member is a positioning protrusion formed on one of the fixing member and the base member and a positioning formed on the other, on the other end in the width direction of the rod-shaped light guide member. The pair of screw fixing portions that are positioned by fitting with the holes and fix the base member and the cover member to each other are positioned substantially symmetrical with respect to the rotation center axis of the base member and are One screwing fixing part located on the positioning side of the fixing member around the rotation center axis is arranged so as to be closer to the other end in the longitudinal direction of the rod-shaped light guide member than the other screwing fixing part. The end face on one end side in the longitudinal direction of the optical member is also characterized in that it is inclined with respect to the longitudinal direction on the same side as the positional deviation with respect to the longitudinal direction of the rod-shaped light guide member in the pair of screw fixing portions.

  In such a light emitting device for a gaming machine structured according to the present invention, the fixing and fixing of the fixing member to the base member, that is, the fixing of the rod-shaped light guide member to the base member is performed in one direction in the width direction of the rod-shaped light guide member. Side screwing and uneven fitting on the other side in the width direction of the rod-shaped light guide member, that is, fitting between the positioning protrusion and the positioning hole. Such positioning by the concave and convex fitting can prevent a heavy object such as a screw from being present around the rotation center axis line, for example, as compared with the case where the portion is also screwed. Thus, it is possible to reduce the burden on the electric motor during rotation of the light emitting device for gaming machines. As a result, it is possible to employ an electric motor with a small overall size.

  In addition, the uneven fitting as described above can reduce the arrangement space on the base member as compared with screwing that requires a member such as a screw, and only the space that can be omitted of other members. Can be used for placement.

  Furthermore, the pair of screw fixing portions that fix the base member and the cover member to each other are disposed at substantially point-symmetrical positions about the rotation center axis of the base member. As a result, the position of the cover member that is substantially point-symmetric about the rotation center axis of the base member is pressed against the base member, and the fixing of the cover member to the base member is stabilized.

  Therefore, as described above, it is possible to arrange a pair of screw fixing portions at positions that are substantially point-symmetric about the rotation center axis of the base member, that is, a compact base member, that is, a base member having a radius as small as possible. In particular, the screw fixing side of the fixing member that tends to occupy a space becomes an obstacle, for example, a pair of screw fixing parts are arranged on the base member in a direction perpendicular to the longitudinal direction of the rod-shaped light guide member. It becomes difficult.

  Therefore, in the present invention, one screwing fixing part positioned on the positioning side of the fixing member around the rotation center axis of the base member is closer to the other end in the longitudinal direction of the rod-shaped light guide member than the other screwing fixing part. Are arranged as follows. That is, in the present invention, by utilizing the space formed by adopting the concave and convex fitting as described above, one screw fixing portion is longer in the longitudinal direction of the rod-shaped light guide member than the other screw fixing portion. As a result, even in a compact base member, the pair of screw fixing portions should be arranged at substantially point-symmetrical positions around the rotation center axis of the base member. Is possible.

  By the way, as described above, when one screw fixing portion is closer to the other end in the longitudinal direction of the rod-shaped light guide member than the other screw fixing portion, the other screw fixing portion is the longitudinal direction of the rod light guide member. It will be arranged close to the end face on one end side, so that the other screw fixing part limits the arrangement space of the substrate. As a result, the size of the substrate is limited when a compact base member is employed.

  Therefore, in the present invention, the end surface on one end side in the longitudinal direction of the rod-shaped light guide member is on the same side as the positional deviation with respect to the longitudinal direction of the rod-shaped light guide member in the pair of screw fixing portions, and the longitudinal direction of the rod-shaped light guide member Is inclined. As a result, in the present invention, the substrate is disposed to be inclined toward the other screw fixing portion having a relatively large space, and the size of the substrate is not limited.

  Therefore, in the gaming machine light emitting device of the present invention, the overall structure can be made compact.

  In the present invention, the electric motor is not particularly limited as long as it is a motor that can be electrically driven and controlled. For example, a conventionally known stepping motor or the like is employed.

  In the present invention, the base member may be directly driven by an electric motor, but it is desirable that the base member is driven via a reduction gear train or the like as a reduction means. As a result, the torque of the electric motor can be amplified and transmitted to the base member. As a result, the overall size of the electric motor can be further reduced.

  Furthermore, in the present invention, the rod-shaped light guide member may be solid or hollow. Furthermore, in the present invention, the material for forming the rod-shaped light guide member is not particularly limited as long as it is a transparent material having a high refractive index. For example, glass, acrylic resin, polystyrene, polycarbonate, or the like is employed. Furthermore, as a method for forming the rod-shaped light guide member in the present invention, injection molding, extrusion molding or the like can be considered.

  In the present invention, it is desirable that a concave portion for accommodating the light emitting source is formed on the end surface on one end side in the longitudinal direction of the rod-shaped light guide member. Thereby, it becomes possible to condense the light emitted from the light-emitting source and to enter the rod-shaped light guide member.

  In the present invention, any conventionally known light emitting source such as a light emitting diode (LED) or an organic EL can be used as the light emitting source. Therefore, in the present invention, the color of light emitted from the light emitting source is not limited to one color. For example, by adopting a full color LED as the light emitting source, it is possible to emit light of many colors. Also good. Further, the number of light emitting sources is not limited to one, and two or more light emitting sources may be employed. Accordingly, when a plurality of light emitting sources are employed, it is desirable that the colors of light emitted from each of the plurality of light emitting sources are different from each other, and thereby various colors can be obtained by combining the colors of light emitted from the respective light emitting sources. It is possible to emit light of various colors.
