Abstract: When displaying a scene on a display screen in which a translucent object and a background object of the translucent object overlap in a virtual space, data of a background object stored in a storage device is continuously read, a translucent calculation is performed between data of the background object and data of the translucent object overlapping the background object, and data of the result of the translucent calculation is continuously written into the storage device. Here, read of the background object data and the translucent calculation, or the translucent calculation and write of data of the translucent calculation result can be simultaneously performed. Further, the translucent calculation can be divided into a plurality of calculations, and the plurality of calculations can be performed simultaneously. With this method, translucent calculation can be performed in a short time.

Abstract: A riding type game machine system includes a vehicle movable along a path with a player riding therein and a plurality of game stages arranged along the path. At least one of the game stages is adapted to perform a contact type game having an input operation performed by the player touching a target. The contact type game is, for example, a target hitting game, which is a familiar game for the player compared with a non-contact type game such as a shooting game using infrared ray.

Abstract: A pseudo random number pattern which does not contain the minimum and maximum gradation values of pixels of input image data, and consists of, as elements, threshold values set at nearly equal intervals, is generated, and input image data is binarized by ordered dithering using this pseudo random number pattern. Since the elements of the pseudo random number pattern do not contain the minimum and maximum gradation values of the pixels of the input image data, even when a binary image is input, noise components, i.e., black or white isolated pixels can be prevented from periodically appearing. Since the threshold values of the pseudo random number pattern are set at nearly equal intervals, a dither image with quality as high as that can be obtained by the conventional method can be obtained even when a halftone image is input.

Abstract: An operational input device is operated by an operator to control an image displayed on a projector screen. A grip bar is arranged such that it extends laterally of the operator sitting on a seat. The grip bar is rotatable around each of a vertical axis and a horizontal axis, so that it can freely move about the respective vertical and horizontal axes within a three dimensional space. Therefore, the operator can operate the grip bar as if it is a paddle of a canoe. Since the grip bar extends laterally of the operator, a plurality of operators can grasp the grip bar simultaneously.

Abstract: A simulator for presenting a simulation movement on a display correspondingly to a movement of an operator. The operator rides on a support plate and the support plate can be turned about a vertical axis line and can be tilted about a horizontal axis line. The support plate is equipped with a first reactive force applying device and a second reactive force applying device. The first reactive force applying device holds the support plate in a natural state in a neutral position with respect to the vertical axis line and applies reactive force to the support plate when the support plate turns from the neutral position. The second reactive force applying device holds the support plate in a natural state in a neutral position with respect to the horizontal axis line and applies reactive force to the support plate when the support plate tilts from the neutral positions.

Abstract: A plurality of medals are placed both on a fixed table and a movable table. A player supplies medals one by one on the movable table via a medal feeding rail. The movable table moves forward and backward in a reciprocating motion to drop medals placed on the fixed table into a medal outlet so as to give the medals to the player. A field table which is placed under the fixed table revolves around a tower, while containing a large number of medals accumulated therein, thereby circulating a large number of accumulated medals. Medals in the field table are automatically taken out, when the amount being in excess, by an overflow prevention device. Thus, the game machine permits the player to continue the game, free from concern about any medal overflowing from the field table.

Abstract: A steering wheel device used for driving simulators or the like utilizing a steering wheel is designed so that when the steering wheel rotates, the steering wheel shaft and the stopper arm rotate. The auxiliary shaft then rotates in the opposite direction by the engagement of a first gear wheel and a second gear wheel so as to rotate the stopper. The number of teeth of the second gear wheel is greater than that of the first gear wheel so that the steering wheel makes more than one revolution. The stopper arm is designed to hit the stopper to limit the rotation range of the steering wheel. The rotation torque of the steering wheel acts only between the stopper and the stopper arm and not between the gear wheels. As a result, the load applied to both gear wheels decreases so as to increase their service life and eliminate the necessity to employ highly strengthened gear wheels.

Abstract: A gun game machine from where a player takes out and holds a model gun to play a game. When the number of operations of a trigger lever (6) attains the preset number of times, the game is stopped and, at the same time, a solenoid (20) operates to disengage a boss (23) of a lever (19) from a recess (22b) of a advance and retreat member (15) and the advance and retreat member is ejected down by the effect of a spring (24). When the player pushes up the advance and retreat member (15) to set, a sensor (16) detects the pushing action and resets the trigger count value for enabling the game to continue. The action of pushing up the advance and retreat device (15) is similar to the real action of loading a cartridge into a real gun and the player can enjoy a game having realism.
