Description

  The present invention relates to an electric decoration device for a ball game machine which is attached to the front of a ball game machine or a game board, and which enhances the electric decoration effect by turning on or blinking a light source provided inside.

  Conventionally, a ball game machine such as a pachinko machine has an illumination device on the front side of the game board as described in Patent Documents 1 and 2, and the illumination device blinks according to the movement of the pachinko ball and the winning state. As a result, the player's euphoria is improved. This electric decoration device is attached to the front of the electric decoration device, a light source such as an LED provided at a predetermined interval or at an appropriate interval inside the case, a reflector (reflector) provided around the light source if necessary. The lens cover is made up of.

  In the conventional illumination device, in order to irradiate a wide area, as shown in FIG. 7, considering the thickness limitation of the ball game machine and the directivity of the LED, an interval of 5 mm to 10 mm is provided inside the case 511. A number of LEDs 513 are arranged side by side at T, and the effect of illumination irradiated from the LED 513 to the lens cover 515 is ensured.

  However, in order for light to diffuse from the directivity of the LED 513 to the lens cover 515, a certain optical path length is required from the LED 513 to the lens cover 515, so that the thickness of the illumination device increases and the thickness is limited. Installation in the installation space is difficult. Further, even when a large number of LEDs 513 are arranged as a light source, there is a limit to the diffusibility in the vicinity where the irradiation ranges of the LEDs 513 overlap. Furthermore, in order to ensure a wide irradiation area, it is inevitably necessary to install a large number of LEDs 513 at a narrow interval, and the number of LED-related parts such as the LED 513 and the wiring board increases. Not only is the manufacturing cost complicated and the manufacturing cost is high, but also there is a problem that the power must be supplied to a large number of LEDs 513 and the running cost is also high.

  Therefore, the present invention has been proposed in view of the above-described problems, and can increase the optical path length so that light is diffused over a wide range with a small number of light sources, and can also keep manufacturing costs and running costs low. An object of the present invention is to provide an electric decoration device for a ball game machine that realizes a thin electric decoration device.

As a result, the directivity of the light source can be optically improved by using the directivity of the light source as it is without attenuating the light amount of the light source. Further, it is possible to avoid the possibility that the portion of the auxiliary reflector looks dark.
