Electronic Darts Apparatus(b)

The past 20 years there has been a plastic dart target disk, using the shape of plastic each partition by partition 82 plastic blocks together such a target disk, each partition can block independent activities, the partition block surface with dense holes. Darts dart needle plastic, the dart hitting the target surface when the block partition, plastic dart needle usually guided insertion partition surface pores and remain therein, due to the partition of the block is active, the needle insertion hole dart generated impact force behind the partition block hit membrane switch, an electronic switch signal generated by the automatic scoring circuit this signal acquisition and scoring. The plastic of the target due to the automatic scoring can be developed rapidly up, because darts dart needle with soft plastic, they were named as soft darts, this plastic scoring target disk, also known as soft dartboard. The traditional sisal, cork material and metal darts target disk is called hard dartboard and darts hard.

But the soft darts has many limitations: 1, not too soft darts, darts heavy impact damage easily dart needle; 2, too darts hit the partition block noise; 3, the partition block surfaces must be a sufficient number of small distribution hole, leading to double and triple the width of the partition is larger than the standard size; 4, darts into the hole, it is often difficult to pull out, prone to dart off in the needle hole phenomenon; 5, the projection can not be guided needle darts dart high probability into the holes and be ejected.

In recent years, there has been the use of sisal material active partition block structure is similar to soft darts automatically scoring hard dartboard, such as patent No. dartboard 200620070850.X described. This automatic scoring dart still many defects: 1, some of the partition can not be made the standard size, does not meet the standard requirements of the game; 2, because the block is active partition, a partition wall between the district thicker, darts probability is very high rebound; 3, sisal material partition block, low molding accuracy, easily lead to partition the block size of the error and the error count scores activity blocked; 4, sisal production partition target block is solid, the weight much larger than the plastic partition blocks, dart impact strength generated may not be sufficient to bring the partition block the trigger signal.
