Patent ID: 7985125

Claim:
A dart game apparatus, comprising: an image display body which displays an image of a target; a panel body, which has a plurality of holes each having a cross-sectional size substantially the same as that of an end of a soft dart, which is also formed, extending toward each hole, with an inclined surface in a ridge taken as a border between adjacent holes, and which is disposed in front of the image display body, and through which the image can be observed; and a coordinate detecting body which is disposed on a front surface of the panel body and detects coordinates of the position of the soft dart, the end of which is inserted into any of the plurality of holes, wherein the coordinate detecting body has at least four rims, in which, so as to correspond to the four rims, two pairs of a light-emitting sensor section and a light-receiving sensor section for detecting light emitted by the light-emitting sensor section are provided respectively on the rims arranged face-to-face in parallel, and the light-receiving sensor sections out of the two pairs detect blockage of light emissions of the light-emitting sensor sections by the soft dart inserted into the panel body, whereby the coordinates of the position of the soft dart are detected.
