Abstract
電子筆記具(10)は、筐体(101)、操作部(12)及び押圧検出装置(100)を備える。押圧検出装置(100)は、電極(25)と、圧電フィルム(21)と、電極(24)と、基材(90)と、電極(125)と、歪み抵抗素子(41)と、電極(124)と、基材(26)と、グランド電極(126)と、検出部(30)を含む回路(110)とを備える。操作面(12A)が操作者の押圧又は押圧の開放によって変位すると、歪み抵抗素子(41)の抵抗値が変化する。これにより、歪み抵抗素子(41)は、操作面(12A)の変位量に応じた出力を行う。よって、検出部(30)は、積算値を、歪み抵抗素子(41)の出力によって補正できる。したがって、押圧検出装置(100)は、どのタイミングでも積算値を適正に補正できる。
