Document Type and Number:
Japanese Patent JP4495525
Kind Code:
B2
Abstract:
Provided is a pointing device (10) that can be reduced in thickness even if a magnetic field sensor (5) is mounted to a front face of a printed circuit board (p). When a support portion (13a, 21a, 22f) laterally moves, a reverse face of a flexible portion is displaced while being guided away from the printed circuit board due to deformation of a mountain fold flexure portion (13i) as a directional deformation portion (13i, 22c). Therefore, a clearance between the reverse face of the flexible portion (13b, 22a) and the printed circuit board (P) increases, and the magnetic field sensor (5) can be mounted to the front face of the printed circuit board (P), thereby making it possible to reduce thickness of the pointing device (10). At the same time, the flexible portion (13b, 22a) would not be ruptured through sliding contact with the magnetic field sensor (5).
