Description

[Detailed description of the invention] This invention is used in pinball game machines such as pachinko machines.
This invention relates to a windmill installed on a game board on which game balls shot by a ball hitting device roll.

In recent years, in pinball game machines such as pachinko machines,
In order to increase the interest of players, we are not only trying to change the winning ball device to a more complex level and increasing the number of game methods, but we are also using sound and light to stimulate the auditory and visual sensibilities of the players. We are taking steps to satisfy them. For example, as a means to satisfy auditory sensibilities, electronic sounds are played from speakers, and as a means to satisfy visual sensibilities, electrically variable display devices such as lamps are installed on the game board surface.

As an example of satisfying the visual sensibilities of players by providing lamps on the game board surface, a few so-called windmills with lamps have been proposed, in which lamp light is emitted from behind the windmill. However, in conventional windmills with lamps, the windwheel shaft with the wind wheel loosely fitted is directly installed on the transmission radiation plate that transmits the light emitted from the lamp, so the transmission radiation plate may be soiled or damaged by game balls. If the transmitting radiation effect is weakened by attaching a wind wheel, or if the transmitting radiation plate cannot be removed and cleaned, or it cannot be replaced, at least it is necessary to clean the transmitting radiation plate with the wind wheel still attached. Cleaning is time-consuming and uneconomical. Therefore, an object of the present invention is to provide a windmill with a lamp for a pinball game machine in which only the transmission radiation plate that transmits the light emitted from the lamp can be easily removed or replaced.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
