Abstract: Provided is a game system utilizing the LEDs of a controller (20). In a game system (1), an image pickup device (2) takes the image of the controller (20). The controller (20) includes a plurality of input units for performing an operation input to proceed a game, and a plurality of LEDs for expressing a controller number to be set in the controller (20), in a game application to be executed. A game device (10) accepts and reflects the operation input of the controller (20), upon the processing of the game application, acquires the taken image from the image pickup device (2), acquires a position in the taken image of the controller (20) from the positions of the LEDs in the taken image, reflects the acquired position information upon the processing of the game application, and generates an image signal indicating the application processing result based on the operation input and the acquired position information.

Abstract: An operating device used in a game machine for playing a television game includes a main body and first and second finger-manipulatable operating units positioned symmetrically on the main body. The operating device may include first and second grips projecting at spaced positions from the main body, with the first and second operating units being positioned adjacent the first and second grips. The operating device may further include vibration-imparting units for imparting vibrations to the user's hands.

Abstract: An entertainment device or other electronic device having an outward shape improved in functionality compared with that in the related art are provided. The electronic device includes a main housing that is formed in an approximately elliptical cylinder form, and disposed in a such a manner that a longitudinal direction is approximately horizontal to a setting surface, and has medium insertion ports for inserting a portable information storage medium such as an optical disk, and an approximately boxlike base portion attached to a lower portion of the main housing.

Abstract: An operating device used in a game machine for playing a television game includes a main body portion and first and second grip portions protruding from one side of the main body portion. A first operating unit is mounted on one end of the main body portion and a second operating unit is mounted on the opposite end of the main body portion. The first and second operating units are each provided with at least one signal input element operable to generate a signal. A third operating unit and a fourth operating unit are mounted to the main body portion adjacent the first and second grip portions. Each of the third and fourth operating units has at least one signal input element operable to generate a signal. When the first and second grip portions are gripped, the third and fourth operating units can be manipulated by the thumb of the hand gripping the first or second grip portion, respectively. The operating device further includes a vibration imparting mechanism for imparting vibrations to the user's hands.

Abstract: A disk cartridge, which is easy to handle, is provided. The disk cartridge includes a cartridge main body having: an opening facing a disk; and a shutter for opening and closing the opening. A part of the cartridge main body is formed in an approximately semicircular shape. Such a shape allows a user to easily know an insertion direction. Moreover, since the cartridge main body does not have any corners, the insertion into a drive device is simplified. The shutter is provided pivotably for the cartridge main body. Any one of a plurality of types of medium can be provided in the disk cartridge. When the disk cartridge is inserted into an external device such as the drive device, the device receives a signal indicating the type of medium, which is transmitted through an electric terminal, so as to perform a process in accordance with the type of medium.
