Abstract

A dart game apparatus includes an image display body which displays an image of a target; a panel body, which has a plurality of holes each with 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. A coordinate detecting body 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. 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.
