Electronic target device

Abstract

A electronic target device comprises two dielectric sheets, two conductive layers formed on one surface of the dielectric sheets and defining a plurality of contact regions, a plurality of leading wires located on the other surfaces of the dielectric sheets and penetrate the dielectric sheets to connect the contact regions respectively, and a plurality of dielectric grains distributed over the contact regions. A target housing which the dielectric sheets are installed therein with a target member and the opposite ends of the leading wires connect to a circuit board which set in the housing for the shooting practice and competition. When ammo or pellets hit on the target member, one of the dielectric sheets abutting the target member is pressed to touch the other dielectric sheet for the conductive layers electrical connecting each other and produce a target-hit signal for transmitting to the circuit board registered and shown accumulated score.
