Abstract: A vibration device includes a bimorph type piezoelectric element having a first main surface and a second main surface facing each other and a vibration member bonded to the second main surface of the piezoelectric element. The piezoelectric element has a first active region disposed closer to the first main surface between the first and second main surfaces and a second active region disposed closer to the second main surface than the first active region between the first and second main surfaces. When a force generated in the first active region is F1, a force generated in the second active region is F2, and a force by which the vibration member restrains the second active region is Fr, F2?F1?Fr is satisfied.

Abstract: A piezoelectric element includes a piezoelectric body, an electrode layer, and a reinforcing layer. The piezoelectric body has a first main surface, a second main surface, and a side surface. The first main surface and the second main surface oppose each other. The side surface extends in an opposing direction in which the first main surface and the second main surface oppose each other in such a way as to connect the first main surface and the second main surface. The electrode layer is provided in the piezoelectric body. The reinforcing layer is provided on the first main surface. The electrode layer is provided opposing the first main surface and apart from the side surface. When viewed from the opposing direction, the electrode layer has a corner. When viewed from the opposing direction, the reinforcing layer overlaps the corner.

Abstract: In a gaming machine (1) comprising a variable display device (5a to 5c) for variably displaying a plurality of kinds of symbols necessary for gaming, a starting device (20) for starting variable display of the symbols, and a stopping device (21), disposed so as to be operable by a player, for stopping the symbols being variably displayed, wherein, on condition that a combination of symbols displayed when the symbols are stopped constitutes a predetermined special winning mode, the player is allowed to start playing a special game which is more advantageous to the player than is a normal game; an image display (13) for displaying special game information in the special game to the player is provided.

Abstract: A game machine comprises a plurality of cylindrical reels each provided with various kinds of symbols on its outer surface. The reels are axially aligned and independently rotatable about an axis in first and second directions. Part of symbols of the respective reels are displayed on a window having a predetermined winning line crossing over the symbol of the respective reels to define the symbols on the winning line as a symbol combination The reels start rotating in the first direction in response to an operation of a start lever. The reels independently stop rotating in response to respective operations of stop buttons to bring the symbol of the corresponding reel to a standstill on the winning line to obtain the symbol combination after all reels are stopped rotating. The symbols are shifted in the first and second directions within a predetermined waiting time to change the symbol combination.

Abstract: A conventional game machine informs a player that a big hit prize is caused by inner lottery, however, it does not inform the player that a small hit prize is caused. Prize determination (probability lottery processing) is carried out by determining to which prize group in a prize determining table a random number value generated by a random number generator 36 and specified by a sampling circuit 37 pertain (step 103). When a hit flag of a small hit prize is erected as a result of the inner lottery (step 104), a process of emitting small hit informing sound is carried out (step 105). According to the informing sound emitting processing, a speaker drive circuit 43 is controlled by CPU 31 and the speaker 39 emits informing sound A, B, C and D in accordance with the kind of the hit flag of the small hit prize.

Abstract: A game machine informs the player about the prize mode using combinations of the individual stagings by the sound emitting means, the connective staging means and the stop staging means. When rotations of individual reels 3 to 5 are started by operating a start lever 15, a game starting sound 1 or 2 according to a hit flag is generated by sound emitting means. In connection with the stopping of the individual reels 3 to 5 according to the individual operations of individual stop buttons 16 to 18, individual back lamps 57a to 57c are then sequentially staged by connective staging means in the connective display mode according to the hit flag. When all the individual reels 3 to 5 are stopped, the individual back lamps 57a to 57c are then staged by stop staging means in accordance with the hit flag.

Abstract: A game machine is disclosed in which interest in the game is created by the operation of stop buttons 16 through 18, and back lamps 57a, 57b and 57c for illuminating rotating reels 3 through 5. Patterns which differ in accordance with the kind of prize modes are announced to the player, for example, by simultaneously extinguishing the respective back lamps 57a, 57b and 57c of the rotating reels 3 through 5 when the stop buttons 16 through 18 are actuated, and the possibility of erecting a “BB” hit flag, signifying a big hit prize, is announced to the player.

Abstract: A hit expectation sound is emitted from a speaker in accordance with the kind of prize line on which a predetermined, prizewinning combination of symbols is expected to be arranged. The emitted hit expectation sound is transmitted to a player via sound transmitting holes provided in a lower portion of the machine. Based on the hit expectation sound being heard, the player can recognize on which of a plurality of prize lines the predetermined combination of symbols is expected to be arranged. The player can enjoy his favorite hit expectation sound by causing part of the predetermined combination of symbols to be stopped on the prize line that is associated with his favorite hit expectation sound.

Abstract: This invention aims to provide a game machine which can offer exciting and varied game aspect. In the game machine, certain symbol combinations (group [C] and [E]) are set as a prize mode only when they occur in B.B (big bonus) game. The combinations in group [C] are not regarded as a prize mode when they occur during the ordinary regular game. These combinations are new to the player because the player encounters them only when the game shifts to the big bonus game. This gives a fresh impact to the player and the player can enjoy a variety in the big bonus game, which does not occur in the ordinary regular game.
