Abstract: An apparatus for performing a wheel-changing simulation has a mount, a support connected to the mount, and a wheel hub retained on the support. The support moves relative to the mount between a retracted position and an extended position. The hub is located adjacent the mount for securement thereto when the support is in the retracted position, and is located remote from the mount when the support is in the extended position. A method for simulating a wheel-changing operation on a racecar by a member of a pit crew includes the steps of unfastening and removing a wheel hub from a mount, returning and refastening the wheel hub to the mount, and constantly supporting the hub throughout the aforesaid steps. In accordance with one feature, the hub is constantly supported by attaching the hub to a support that is connected to and moves relative to the mount. In another feature, the hub is constantly supported such that an axis of the hub remains in fixed orientation relative to the mount.

Abstract: A game apparatus determines a contact situation between a player character and an enemy character on a display screen (step S200), identifies a contact pattern for the determined contact situation (step S300), determines an arrangement pattern based on the contact pattern identified (step S400), and displays the characters in a battle scene according to the determined arrangement pattern.

Abstract: To enable an easy grasp of a positional relationship of the respective characters within a fighting field.A specified fighting field and two character images are displayed on a monitor 7 by a control of a controller 8 based on an image data stored on a storage 6, and the motions of the respective character images are operated by operation keys of first and second operation units 1, 2. Further, a window display unit 11 reads the image data of the image being displayed from the controller 8, forms a window screen smaller in size than the screen of the monitor 7 in a position within the monitor 7 where the window screen does not hinder the motions of the two character images, and gives a display command to the controller 8 so as to display the fighting field centering around the two characters, and symbols P1, P2 representing the two characters.

Abstract: A simulative quick-firing gun includes a shooting detector and an impact generator for generating an impact in accordance with detection of a shooting. The impact generator includes a motor, an impacter movable reciprocatingly in a specified direction of the housing, and a conversion mechanism for converting a torque of the motor to a reciprocating movement of the impacter. The impacter is provided with an impact weight member and a reciprocating rod carrying the impact weight member on an end thereof and operatively connected with the driving rod by a linking mechanism.
