Title: Pen for input device
Inventor: OTANI MITSUHIRO
IPC: G06K11/06
Filed: 1984-08-11
Abstract: PURPOSE:To eliminate a feeling of a stroke of the upward/downward movement of the pen during writing operation, and improve writing performance by turning on a switch for the 1st stage under weak pen pressure and turning on a switch for the 2nd stage under strong pen pressure, and detecting the pen pressure in two stages. CONSTITUTION:Pressure when applied through a pen shaft 2 is applied to a rubber switch 3 and pressure sensitive conductive rubber 4. Then, the flexion part 3b of the switch 3 flexes under low pen pressure firstly to press a contact part 3e against the opposite electrode parts 5b of an opposite electrode plate 5, and electric conduction induced between the opposite electrodes to turn on the 1st- stage switch. Further, when the push pressure from the pen shaft 2 increases, the strong push pressure from the pen shaft 2 is applied through the pen shaft 2, switch 3, electrode plate 5, spacer 7, and opposite electrodes 6. Consequently, conductive particles in the rubber 4 contact one another and the rubber 4 becomes electrically conductive to cause electric conduction between the opposite electrodes of the opposite electrode part 6b of the electrode plate 6 contacting it, thereby turning on the 2nd-stage switch. Thus, the pen pressure is detected in two stages.
