Abstract: There is provided a game machine comprising: a game machine main body provided with a field where a game is played on an upper surface side thereof; and a plurality of monitors each being configured by using a flat panel display, and presenting information relating to the game to a player, wherein the game machine is provided: a support structure supporting each of the monitors above the field; and a connection device connecting each of the monitors with the support structure, and the connection device is provided with a monitor drive mechanism that moves the plurality of monitors so that a direction of display surface of each of the monitors is changed by force from a predetermined drive source.

Abstract: There is provided a game system for improving a maintenance property of a game machine in which a replacement part is provided. A replacement part D has a part information recording device 34c in which uniquely given part identification information is recorded. A game machine main body K includes a part information obtaining device 24 and a server transmission device 23. The part information obtaining device 24 obtains the part identification information. The server transmission device 23 transmits to a center server CS, game machine identification information uniquely given to a game machine G together with the obtained part identification information. The center server CS has a server storage device 12 for storing the received part identification information and the received game machine identification information in association with each other.

Abstract: The invention provides a game machine enabling to reduce the load of the maintenance of a running surface by using the guide line detecting function of a self-running body. The game machine includes a game machine main body (10) having a running surface (18) on which a guide line (34) is provided and a self-running body (30) capable of self-running on the running surface (18) and having a guide line detecting device for detecting the guide line (34) and a traveling control device (110) for controlling the running of the self-running body according to the result of detection by the guide line detecting device. The guide line detecting unit is a line sensor (50) having light-receiving elements arranged in the lateral direction of the self-running body (30) to detect the luminance distribution in a predetermined detection region including the guide line (34) of the running surface (18).

Abstract: The invention provides a field unit of a game machine, wherein a lower-stage running surface on which a self-running body is placed can be maintained efficiently. The field unit of a game machine includes a lower-stage running surface on which a self-running body runs; and an upper-stage running surface on which a model following up the self-running body runs. In the field unit of a game machine, the lower-stage running surface is formed in a lower structure, and the upper-stage running surface is formed in an upper structure which is liftably combined with the lower structure. The upper structure is raised and lowered with a lift drive device.

Abstract: A number drawing apparatus includes a rotating unit and collecting holes. Each ball, supplied from a supply unit provided in the central portion of the rotating unit when it rotates, randomly rolls on a surface of the rotating unit. A centrifugal force by the rotation causes each ball to move outwardly from the rotating unit, and each ball is caught in one of catching holes. Unique identifying symbols are assigned to the catching holes. This enables the draw.
