Description

  The present invention relates to a pachinko machine capable of satisfying both visibility by increasing the size of a symbol of a symbol display device and securing a region where balls fly in a game region.

A pachinko machine in which a decorative part is provided in an inner game area surrounded by guide rails of a game board and a symbol display device is provided on the back side of the decorative part is known (for example, see Patent Document 1). The decorative part is provided with three symbol visual recognition parts arranged in a horizontal line as viewed from the player located in front of the pachinko machine at a distance from each other. Therefore, the player can see the symbol of the symbol display device arranged on the back side of the game board from the front of the pachinko machine through the symbol visual recognition unit. By the way, recently, there is a tendency to increase the size of the symbol in order to make the symbol of the symbol display device easier to see. With the increase in size of the symbol, the symbol visual recognition part of the decorative component becomes larger and the decorative component also becomes larger. There is a tendency. However, by increasing the size of the decorative part, the area that the decorative part occupies the game area becomes large, and the area where the balls fly in the game area becomes small. In the case of a decorative part provided with the above three horizontal line visual recognition parts described above, if the size of the decorative part is increased by increasing the size of the design, the distance between the left and right ends of the decorative part and the guide rail is reduced. The area where spheres fly in the area is reduced. Further, a rotary display device in which a plurality of symbol visual recognition parts are provided on a cover and a symbol display is provided on the back side of the symbol visual recognition part is known (for example, see Patent Document 2). There is no description on how the cover of this rotary display device can be attached to the game board, but if this cover is a decorative part attached to the front of the game board, the design will be large. If the decorative parts are made larger in size, the game parts are occupied by the decorative parts, and the area in which the balls fly in the game area is reduced. In other words, if the size of the decorative part increases and the area where the balls fly in the game area is reduced, the original playability of the pachinko machine that enjoys the flying of the balls falling in the game area is impaired. In addition, in the conventional rotary display device in which a plurality of symbol visual recognition portions are provided on the cover, in the case of a configuration in which two symbol visual recognition portions are provided on the cover in order to display two symbols, the symbol is enlarged to cover. However, even if the size is increased, the occupation area occupied by the decorative part can be reduced, but in this case, a so-called reach state in the symbol matching game cannot be produced. Further, in the case of a configuration in which four or more symbol visual recognition parts are provided on the cover, if the symbol is enlarged and the cover is also enlarged, the occupied area of the game area by the decorative part increases. Also, in the case of a configuration in which four or more symbol visual recognition parts are provided on the cover, if the symbol is enlarged and the interval between adjacent symbol visual recognition parts is set to allow the passage of the sphere, There are fewer game areas to fly around.

If the ball enters the start-in guide guide rod 94 of the back member 38 via the guide groove 108 in the second stage 87, the ball proceeds into the start-up winning guide passage 89 of the main body 36, and the start winning component 26 Since it is discharged to the game area 15 from the outlet 110 of the start winning guide passage 89 located immediately above the entrance, there is an increased possibility of winning the start winning component 26. In some cases, the ball does not enter the guide groove 108 in the second stage 87 and falls to the game area 15 via both sides of the lower end of the second stage visual recognition hole 82 connected to the second stage 87. When the ball is awarded to the start winning component 26, the control device receives a start winning detection signal, performs a winning lottery, changes the display by the main special symbol display device of the main special symbol display section 23A, and displays the sub special symbol display. The design of the rotation display structure 121 is changed by rotating and revolving the rotation display structure 121 by controlling the rotation driving mechanism of the three game rotation display devices 35 functioning as devices. If the winning lottery result is a winning result, the control device, for example, has the same winning symbol as three sub-special symbols to be shown to the player through the three symbol visual recognition parts 55 to 57 based on the winning result. The rotation display structure 121 of the three game rotation display devices 35 is controlled to be stopped and displayed as a main special symbol to be displayed on the main special symbol display unit 23A. The control device executes the game when it receives a stop completion signal for the main special symbol. That is, the control device controls an unillustrated opening / closing drive source of the opening / closing body 27a of the variable prize component 27, and a series of games called per-game that opens and closes the opening / closing body 27a for a predetermined number of times or a predetermined time is performed. When the ball launched into the game area 15 passes through the operation hole 29a (see FIG. 2) of the operation component 29, the control device inputs this passage detection signal, and the control device performs normal symbol lottery and normal operation. The symbol by the normal symbol display device of the symbol display unit 23B is changed. If the lottery result is a win, the control device stops and displays the symbol displayed on the normal symbol display unit 23B based on the win result, and opens and closes the opening / closing body 26a called a tulip of the start winning component 26 a predetermined number of times. .

  You may make it each center 48a-50a of the symbol visual recognition holes 48-50 of the three symbol visual recognition parts 55-57 be located in the vertex of the equilateral triangle 50. FIG.
