IPC: G06F3/041
Filed: 1984-05-30
Abstract: PURPOSE:To keep the stable sensing pressure for a long period by pushing out an action rod piercing through a coil-shaped spring matter with an end of said spring matter, also pressing a contact member set at said tip end to a fixed contact member and separating both contact members from each other when the action rod is pushed inside. CONSTITUTION:An action rod 34 of a holder 14 for input pen of an electronic blackboard is put through a coil-shaped spring matter 29 having an end 30 fixed into a hole 31 of a terminal plate 22 with electrical insulation. The head part of the lever 34 touches the other end of the matter 29, and this touch degree is defined at a distance l by a flange.
