Abstract: An operation device according to the present invention includes a touch-sensitive operation surface placed in a vehicle and a detecting unit configured to detect touch operation by an operator on the touch-sensitive operation surface. On the touch-sensitive operation surface, a guide part having a convex shape or a concave shape and a planar operation part to be an operation location having a planar shape located around the guide part are formed. The detecting unit is configured to detect slide operation on the guide part from the planar operation part, and accept later operation on a predetermined operation location as an operation instruction set in accordance with a status of the slide operation on the guide part.

Abstract: In a game system including a wireless LAN AP instrument and a portable game device, the AP instrument transmits a beacon signal including a MAC address of the AP instrument and a network ID obtained by encoding an instruction code so that the network ID can be decoded using the MAC address. The portable game device decodes the network ID included in the received beacon signal using the MAC address, and executes control based on control data when authenticity determination data included in the decoded instruction code coincides with specific data and the present date is within a valid period indicated by valid period data.

Abstract: When an insect character generation control section has detected reception of a beacon periodically transmitted from an AP located in the current wireless communication area of a player's device, the insect character generation control section detects the MAC address of the AP which has transmitted the beacon. When the detected MAC address does not coincide with the previously detected MAC address, the insect character generation control section determines whether or not to generate an insect character according to a generation rate calculated by a generation frequency adjustment section. When the insect character generation control section has determined that an insect character is to be generated, the insect character generation control section determines the type of insect character to be generated by referring to insect character information, and displays a video image of the insect character on an insect cage screen on a lower screen.

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.
