  • Patent number: 6708976
    Abstract: A dart board includes at least one flexible slot which includes at least two apertures for receiving the dart tips. A through hole is defined between the two apertures so as to expand the flexible slot and the dart tips having different sizes can be clamped by the flexible aperture. A guide plate is fixed to the retaining frame so as to guide the dart tips to successfully stick on the dart board and activate the electronic film switches of the dart board. The size of the retaining frame can be reduced because of the fixed guide plate. The guide plate and the retaining frame are engaged by engaging members and engaging holes so that the guide plate can be easily replaced. The guide plate can be fixed to the retaining frame.
