Abstract: 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.

Abstract: 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.

Abstract: In a game machine, a reel unit is disposed behind each display window. The reel unit has an outer reel and an inner reel which coaxially rotate. The inner reel carries plural inner symbols at a certain pitch. The outer reel carries plural but less outer symbols. The outer symbol has a larger size than the inner symbol, and is opaque. The outer symbol on the inner symbol hides the inner symbol. A symbol combination is formed of only plural inner symbols, or at least one of the inner symbols and at least one of the outer symbols.

Abstract: A slot machine includes a rotatable reel which is cylindrical shaped. The reel is provided with a first display portion on a side surface and with a second display portion on a periphery. In performing a first game, the side surface is so perpendicular that the first display portion may be observable. In performing a second game, the periphery is so horizontal that the second display portion may be observable.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A symbol display device includes a first rotary disk with a small diameter and a second rotary disk with a large diameter, which rotate independently while overlapping with each other. A driving shaft, which is firmly fixed to the center of the first rotary disk, is penetrating a hole formed at the center of the second rotary disk. A plate-shaped flange is fixed to the second rotary disk so as to fill in the hole. A driving pipe is firmly fixed to the flange, and the driving shaft is rotatably inserted in the driving pipe. A first stepping motor is connected to the rear end of the driving shaft protruding from the driving pipe, to which a large pulley is firmly fixed. A small pulley is fixed to the driving shaft of a second stepping motor. Rotation of the second stepping motor is transmitted to the second rotary disk through a timing belt.

Abstract: 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.

Abstract: 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.

Abstract: A game machine has plural reel rows for performing the slot game independently. Each reel row includes plural reel units arranged side by side. The reel unit is a double-reel, which consists of an inner reel and an outer reel rotating independently with overlapped. The inner reel and the outer reel carry plural symbols. Symbols of the inner reel are observable through the outer reel. Stop position of each outer reel is determined by lottery so that symbol arrangement by the outer reels become common in all reel rows. Each inner reel stops at the independently determined position.

Abstract: 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.

Abstract: Symbol-image windows are arranged in matrix of three rows and five columns. Five game lines to be nominated are provided so as to horizontally and diagonally combine the symbol-image windows. Jackpot winning occurs when identical symbol images are displayed at one of three groups of the symbol-image windows. The first group is constituted of the first to third columns. The second group is constituted of the second to fourth columns. The third group is constituted of the third to fifth columns. When the identical symbol images are displayed at one of the five columns, sub-game winning occurs to award a sub game in which a symbol-image series is rotated again in the central symbol-image window. In another embodiment, ten game lines to be nominated are provided so as to vertically, horizontally and diagonally combine the symbol-image windows.

Abstract: Symbol displaying windows are arranged in matrix and are combined to set game lines including three horizontal lines, three vertical lines, and two diagonal lines.
