A slot machine includes a reel assembly which has a transparent outer reel and a translucent inner reel disposed coaxially within the outer reel. The outer and inner reels are provided with first exterior surfaces on their periphery, and with second exterior surfaces on their side surfaces. The outer and inner reels are driven independently by a respective motor. In performing a first game, the side surfaces are horizontal so that first outer symbols and first inner symbols carried on each of the first exterior surfaces may be observable. In performing a second game, the side surfaces are perpendicular so that second outer symbols and second inner symbols carried on each of the second exterior surfaces may be observable. Symbol combinations are produced by synthesizing the symbols on the outer reel and the symbols on the inner reel.

Symbol display device for game machine

A first symbol and a second symbol constituting a composition symbol 'horse' are arranged on an inner reel and an outer reel respectively. When the outer reel is rotated and it is determined to display the composition symbol, the inner reels of first though third reel units are stopped so as to align the first symbols at a reference position, which is set relative to a central game line. After that, the outer reels of the first through third reel units are rotated and are stopped so as to align the second symbols on the central game line. When aligning the composition symbols 'horse' on the central game line, the inner reel is rotated by a predetermined angle in forward and backward directions. This operation is carried out prescribed times to perform dynamic attraction in that pupil of the horse is changed.

Symbol displaying unit for a game machine

A symbol display device is provided with a first reel unit, a second reel unit, and a third reel unit. Each of the first, the second, and the third reel unit is composed as a double reel structure with an inner reel and an outer reel. The inner reel and the outer reel are formed out of light-transmittable material and have translucent symbols arranged on their peripheries. A first light-emitting device is provided inside the inner reel to illuminate the symbols on the inner reel from behind of them and a second light-emitting device is provided between the inner reel and the outer reel to illuminate the symbols on the outer reel from behind of them. In order to illuminate the symbols on the outer reel, only the second light-emitting device is lit up, while the first light-emitting device is lit up in order to illuminate only the symbols on the inner reel.

An inner reel is provided with an A-zone, a B-zone and a C-zone. Symbols of the inner reel are arranged in the respective zones. The A-zone to the C-zone are selectively displayed in accordance with a game condition. The A-zone is used in a normal game. The B-zone and the C-zone are used for deciding a sort of benefit to be afforded in a free game. Either of the B-zone or the C-zone is used in the free game. Using the B-zone brings the benefits in that winning provability is raised and in that odds are increased in case of winning. Using the C-zone brings the benefit in that a number of the free games are added.

Symbol-displaying device for a game machine

A symbol display apparatus for game machine includes lined up plural reel units. Each reel unit has double reel structure composed of an outer reel and an inner reel. Inside the inner reel, backlights are disposed. Peripheries of the outer and inner reels are so colored lightly as to be semitransparent, so the outer and inner reels make an object disposed inside indistinct but transmit light. Inner symbols arranged on the periphery of the inner reel are printed with light color. When the inner and outer symbols are overlapped, the backlight emits white light. Color of the inner symbol illuminated with the white light does not affect adversely to appearance of the outer symbol. When the inner symbol is displayed through a transparent portion provided in the outer reel, the backlight emits light color of which is correspondent to the inner symbol for displaying the inner symbol emphatically and clearly.

Symbol display apparatus for game machine

Transparent blank symbols are disposed on each of first, second and third display parts respectively provided in first, second and third display plates. The player wins if the same symbols of the first to third display parts are arranged in line on any of winning lines when the first to third display plates stop rotating. When the blank symbols of the first to third display parts are arranged in line on any of winning lines, the reel mounting plate starts rotating until the sub reel reaches the position behind the blank symbols. Then, the sub reel rotates and stops to display move and stop of the symbols. The symbol on the sub reel is observable through transparent parts in the blank symbols.

Fifteen reels are arranged in five lines and three columns. Plural kinds of symbols are drawn on each reel at a constant pitch, so that one symbol is observed through a display window. There are three type winnings, such as a line winning, which is completed when predetermined symbols are lined on the winning line, a block winning, which is completed when predetermined symbols are displayed from a group of display windows, and an ANY position winning, which is completed when a fixed number of predetermined symbols are displayed. When one of winnings is completed, the symbols constituting the winning is illuminated by a specific color allocated the winning.

Symbol display device and game machine

Transparent blank symbols are provided in each of first, second and third display plates. The player wins if the same symbols of the first to third display plates are arranged in line on any of winning lines when the first to third display plates stop rotating. When the blank symbols of the first to third display plates are arranged in line on any of winning lines, the sub reel rotates to display the symbols in motion. Then, the sub reel stops its rotation to display the still symbol. The symbol on the sub reel is observable through transparent parts in the blank symbols.

Behind a display window, plural of reel units are disposed. Each of the reel units has an outer reel and an inner reel that are coaxially and independently rotated. The inner reel carries plural inner symbols at a predetermined pitch. The outer reel carries outer symbols representing conditions of a second rotation of the inner reel. The plural inner reels stop rotating to complete a symbol combination. When the symbol combination for losing is completed, the outer reel is rotated and stopped. Then the second rotation of the inner reel starts rotating, which carries the inner symbol on which the outer symbol is disposed. In the second rotation, a rotational direction and a rotational speed is determined in accordance with a kind of the outer symbol. When the second rotation of the inner reel stops, another symbol combination is completed on the winning line.

A game machine is provided with first, second and third reel rows, and each of the reel rows executes slot game independent from each other. The number of reel rows to be actuated is increased in proportion to the number of bet coins. When less than three coins are betted, a first privilege providing section is operated to judge whether the first winning is generated. The first and a second privilege providing sections are operated to judge whether the first winning and a second winning are generated when four coins are betted. Dividend coins are provided in the first winning and a free game in the second winning. A player may play slot game without betting a coin in the free game.

Game machine

A symbol display apparatus for game machine includes aligned plural reel units. Each of the reel units has double reel structure composed of an outer reel and an inner reel. Of two half symbols made by dividing a single complete symbol, one half symbol is disposed in a periphery of the inner reel, and the other half symbol is disposed in a periphery of the outer reel. When the corresponding half symbols disposed separately in the inner and outer reels stop together on the same winning line, a composite symbol is formed. The composite symbol is used as a hit symbol which makes up a winning symbol combination.

First-third light emission parts, wherein plural LEDs are disposed, are provided in front surface of a first display plate. Synchronized with the rotation of the first display plate, the LEDs in the light emission part light on and off to display symbols or images by utilizing afterimage effect. When the first display plate stops rotation, the first-third light emission parts are lighted on and off sequentially. When one of the first to third light emission parts is lighted on, an amount of dividend coins is determined by the numbers on a second display indicated by the lighted light emission part and a fixed indicator. Thus, the LEDs in the light emission part are used not only as image display device but as an indicator.

A rotary reel unit for a game machine mounted to a frame through a support member fixedly provided in a vertical state, the rotary reel unit including a fixing member fixed to one of sidewalls of the support member, having a attachment base plate; a movable member provided at the attachment base plate, having a photograph sensor to an index provided to the rotary reel; the attachment base plate provided at least one engaging member; an engaged plate part of the movable member having a plurality of engaged plate parts provided continuously thereto on the base line L positioned at the same direction as a circumferential direction of the rotary reel; and the engaging member detached to the engaged plate parts in serial when the position of the photograph sensor is re-positioned by controlling the movable member so that the position of a sensor is enable correcting easily by a person who is not an expert.
