Pen input device and used sensor element

Abstract

A pen-style input device which can measure the pen pressure with small and high sensitive pressure sensor is provided. This invention includes: the main body of the pen( 10 ),the core( 12 ) of the pen fixing on the main body(10 ); the pen pressure senor ( 100 ) forming the electrode pattern on the circuit and detecting the user's pen pressure from the core( 12 ). The characteristic is that: the element of the pen pressure sensor (100) has the pressure sensitive electronic elastomer which opposite to the electrode pattern. The pressure from the core makes the deformation of the pressure sensitive electronic elastomer. Thus, using the change of the resistance of the electrode pattern detects the pressure.

Description

technical field [0001] The present invention relates to, for example, a pen-type input device that communicates with a computer device, a high-sensitivity sensor element used therein, and the like. Background technique [0002] In recent years, a pen-type input device has attracted attention, for example, as an information input device for a computer device. In this pen-type input device, it is known to have an electronic device that digitally records the content written with the pen in addition to the writing function that the original pen has (for example, refer to Patent Document 1: Japanese Patent Laid-Open 2003 - Bulletin No. 308163). In the conventional pen-type input device, various information such as the time used, the inclination angle of the pen, and the serial information of the pen are obtained while reading the position information set on the paper through the optical sensor. In addition, Patent Document 1 discloses a pen type input device provided with a pen...
