[Problems to be solved by the invention]
As described above, in a gaming machine, for example, in a pachinko gaming machine, a change in a symbol that gives the thrill and excitement of a game to a player is produced by mechanically changing the symbol using a rotating drum. It was difficult to do so, and there was no choice but to improve the effect of sound or lighting.
[0008]
Further, the variable display device of Patent Literature 1 allows a roller provided at a position facing a player among a plurality of rollers to be movable by a slide mechanism, and controls the drive of the slide mechanism when a predetermined condition is established in the game. The roller is slid back and forth, but this is because the roller slightly protrudes toward the player side and the identification information formed on the outer peripheral surface of the belt-shaped variable display member passing through this roller portion is only deformed. When viewed from the front of the player, it is considered that the effect of obtaining a thrill, excitement, and the like is small because of poor three-dimensional effects.
[0009]
Further, in the so-called reach state or jackpot state, the three-dimensional display game machine disclosed in Patent Document 2 displays a pattern displayed on a rotating drum in a manner that a predetermined number of symbols are projected out of a normal three-dimensional image and displayed. In this method, image data is output to a three-dimensional display unit to be displayed to form a three-dimensional effect on a symbol. In this method, for example, a rotating drum, that is, a symbol is moved so as to protrude toward a player, and a three-dimensional image is formed. Since it does not form a feeling or depth, it is considered that the reality of actually entering the player's vision is poor.
[0010]
Furthermore, the symbol display device in the pachinko machine of Patent Document 3 displays symbols on both sides of the symbol display belt to increase the number of symbols per unit length of the symbol display belt. The effect is difficult to understand, and does not give a thrill or excitement to the player due to the change in the design.
[0011]
The present invention has been made in view of the above point, and in a method of mechanically changing a symbol, that is, a method of changing a symbol by rotating a rotary drum, displaying a change in a symbol that gives a thrill or excitement to a player. It is an object of the present invention to provide a symbol display device for a gaming machine.
