Abstract: A position detection system includes a position detection section which detects irradiation positions of gun controllers GC1 and GC2 based on images from an imaging device, and a determination section which determines that which of the gun controllers GC1 and GC2 irradiates which of the detected irradiation positions. The gun controller GC1 emits a beam in a first emission pattern, and the gun controller GC2 emits a beam in a second emission pattern differing from the first emission pattern. The determination section determines that the irradiation position is the irradiation position of the gun controller GC1 when the irradiation pattern formed at the irradiation position in the images of a plurality of frames is a first irradiation pattern, and determines that the irradiation position is the irradiation position of the gun controller GC2 when the irradiation pattern is a second irradiation pattern.

Abstract: The objective of this invention is to provide a game controller capable of using synchronizing signals to obtain accurate coordinates of an indicated position. Cables (22) and (24) transfer a video signal from a video output terminal of a main game machine unit and a control signal to a controller terminal. An HV separator (150) separates vertical and horizontal synchronizing signals from the video signal. Light from an aimed-at position is detected by a photosensor (154) provided within a gun (20), and a position computation section (162) obtains the coordinates of the aimed-at position, based on a detection pulse at that point and synchronizing signals from the HV separator (150). The cable (22) is connected to the cable (24) within a connector (36) so that a video signal and control signals are transferred by the cable (24). The video output terminal is connected to a video input terminal and a second game controller by using a connector (30) having male and female terminals (32) and (34).

Abstract: It is an object of the present invention to provide a general purpose controller for a game machine by which a car game of a fishing game can be more enjoyed. A controller for a game machine comprises a jog dial 5 rotatably mounted on a controller main body 1 as a part of an input operating part, a data input system 20 driven according to and connected to the jog dial 5 to input data in accordance with the rotation of the jog dial and a counterforce urging means having a driving motor 17 or the like driving connected to the jog dial 5 for urging a counterforce opposite to the rotation thereof.
