Abstract: A lens driving apparatus may include a movable body holding lenses; a support body for supporting said movable body to move in the optical axis direction of said lenses; and a drive mechanism for driving said movable body in the optical axis direction; wherein said movable body is provided with an extension portion that is extended toward the outer periphery, and a moving path and a movement-stopping portion are formed to at least a member of said drive mechanism mounted on the support body or to said support body, said moving path allowing said extension portion to move in the optical axis direction when said movable body is moved in the optical axis direction and said movement-stopping portion regulating the moving range of said movable body as said extension portion makes contact with said movement-stopping portion.

Abstract: In a game management server that manages a network multiplayer game, a game-holding-prior-notice-receiving unit receives a date and time for a prospective multiplayer game being held, and conditions for holding the game, and the unit registers them into a database. An entry-reservation-receiving unit announces a prior notice of the meeting being held and calls for participants. A user who desires to participate requests the entry-reservation-receiving unit to make an entry reservation. When receiving the entry reservation, the entry-reservation-receiving unit registers the reservation into a database. When the date and time that the meeting is expected to be held arrives, the execution managing unit generates data necessary for executing the meeting and manages the execution of the meeting to be held. A result presenting unit presents the result of the meeting.
