table screen 1306 is scanned by onesensor 1305, the present invention can be realized in a case that a plurality ofsensors 1305 are provided and each of thesensors 1305 scans an area allotted on thetable screen 1306. For example, it may be constructed that twosensors 1305 are provided and onesensor 1305 scans the right half area on thetable screen 1306 and theother sensor 1305 scans the left half area on thetable screen 1306. - According to the position detection method mentioned above, even if plural players indicate the positions on the
table screen 1306 at the same time, each player corresponding to each of the indicated positions can be recognized. -
FIG. 19 shows a flowchart of the position detection process for detecting the position indicated by the indication portion P through thesensor 1305. - At first, the
sensor 1305 conducts the position detection process (step S1901). Thesensor 1305 scans over thetable screen 1306 by the scanning light and determines whether or not reflection of the scanning light exists. If the reflection of the scanning light exists, thesensor 1305 measures strength and light quantity of the reflected light and specifies the direction of the reflected light and the distance to the indication portion P, thereby conducts calculation about the position. - Next, the
sensor 1305 outputs the calculated position as the position information (for example, x, y coordinate values) (step S1902). Here, thesensor 1305 may output both the position information and the discrimination information of the player (for example, player's number). - The position information is output to the
game control portion 1502. Thegame control portion 1502 determines the image to be displayed on thetable screen 1306 and/or thefront display portion 1302, based on the position information received, and instructs the screenimage control portion 1501, theDLP 302 and the frontdisplay control portion 1504 to conduct the image display process (step S1903). For example, if thegame control portion 1502 determines the position information as indication of any of theareas game control portion 1502 instructs the screenimage control portion 1501 to display chip image indicated within such areas, thereby the screenimage control portion 1501 produces image data corresponding to the instruction. - As mentioned above, it can be realized the
gaming machine 1301 in which thetable screen 1306 is utilized for both the image display device and the input device. - Next, the third gaming machine embodiment according to the present invention will be described.
