  When the main control device 148 wins the combined control device 149 with the result of the output lottery processing together with the production stop signal, the liquid crystal display 65 is given a hit like the form in which the same special symbols are arranged in a line, for example. At the time of stop display, main controller 148 drives variable drive source 162 for a predetermined number of times and for a predetermined time. The number of special symbols that are stopped and displayed in the above-described case is not limited to three, and may be one, two, four, or more. By opening the variable drive source 162, the open / close body 138 of the variable winning component 135 is opened and closed based on the predetermined number of times and a predetermined time. The operation by the variable winning component 135 is a jackpot game. That is, the ball taken into the variable winning component 135 while the opening / closing body 138 is opened is detected by either the normal winning ball detector 158 or the specific winning ball detector 159. The main controller 148 counts up the elapsed opening time of the opening / closing body 138, and counts up the number of normal winnings every time a normal winning signal is input from the normal winning ball detector 158. Then, the count-up value based on the elapsed time reaches the set release time such as 30 seconds set in the main controller 148, or the count-up value based on the number of normal winnings is set in the main controller 148. For example, when the set number of normal winnings such as 10 is reached, the main controller 148 stops the variable drive source 162.

  As a result, the opening / closing body 138 of the variable winning component 135 is closed. During the opening / closing of the opening / closing body 138, when a specific winning signal is input from the specific winning ball detector 159, the main controller 148 opens the opening / closing body 138 after the opening / closing of the opening / closing body 138 is completed. The variable drive source 162 is driven to open and close once again, and the round game is counted up once. In the land game in which the opening / closing body 138 opens and closes once again in response to the specific winning signal, the count-up value based on the number of continuations of the round game reaches the set number of continuations such as 16 set in the main controller 148. Repeatedly, one big hit game ends. In addition, for each input of the normal winning signal and the specific winning signal, the main control device 148 issues a winning ball payout signal that is determined in correspondence with the normal winning signal or the specific winning signal and includes the number of winning ball payouts. The payout control device 151 drives the payout driving source 170, and the payout mechanism 107 pays out a ball as a prize ball to the ball storage portion 90 of the ball tray structure 82.

Although the projector 3 may be attached to the back surface of the front cover 7, if the projector 3 is attached to the housing body 6 as in the present embodiment, the projector 3, the reflecting mirror 4, and the screen 5 are accommodated. In a state of being attached to the body main body 6, after properly adjusting the positional relationship of the projector 3, the reflecting mirror 4, and the screen 5 with respect to the optical axis of the projection light from the projector 3, the front cover 7 is mounted on the housing body 6. Therefore, there is an advantage that the positional relationship with respect to the adjusted projection light is appropriately maintained without being shifted.

  The present invention can be similarly applied to the projection device 1 of a slot machine as a gaming machine. In this case, the front side of the gaming machine frame of the slot machine corresponding to the gaming machine frame 71 as a whole or a front surface of the plate-like structure similar to the plate-like structure 113 made of light-transmitting synthetic resin. Or the reflecting mirror 4 is formed in an arc shape that protrudes forward, or the screen 5 is formed in an arc shape that protrudes forward, or a front panel corresponding to the front panel 84. If 84 is formed in an arc shape protruding forward, an image like a drum type can be expressed. The plate-like structure used for the slot machine is different from the plate-like structure 113 in that no gaming parts are provided on the plate-like structure 113.
