Abstract: A dielectric (16) is housed in a chassis (15) having an opening (22) and a main face portion (23). The dielectric (16) is formed with a hole (30) extending from a first surface (28) to a second surface (29) thereof, and the main face portion (23) of the chassis (15) is formed with a through-hole (25). A conductive pin (17) is inserted into the hole (30) and the through-hole (25) with one end portion thereof projected to the outside of the chassis (15) from the main face portion (23). Further, the electrode portion (32) of the lead electrode (18) is interposed between the second surface (29) of the dielectric (16) and the main face portion (23) of the chassis (15), and a terminal piece (33) of the lead electrode (18) is projected toward the outside from the main face portion (23) of the chassis (15). Further, a conductive elastic member (19) is arranged to approach the first surface (28) of the dielectric (16).

Abstract: A position indicator includes a case (2), and a rod (3) housed in the case (2). The rod (3) is passed through a cylindrical ferrite core (6) so that its indicating portion (31) (e.g., pen tip) protrudes from an end of the ferrite core (6). A position detecting coil (4) is wound around the periphery of the ferrite core (6). A switch section (5) (e.g., pressure detector) for detecting the pen pressure of the rod (3) is arranged on the other end of the ferrite core (6). An elastic shock-absorbing member (7) is also attached to the other end of the ferrite core (6), so that the shock-absorbing member (7) is fitted between the ferrite core (6) and the switch section (5). Since any impact force applied to the ferrite core (6) and the rod (3) is alleviated by the shock-absorbing member (7), damage to the ferrite core (6) and the rod (3) can be prevented or reduced.

Abstract: In an input pen having a pen-shaped casing, a ferrite core with a coil wound thereon and a ferrite chip are placed opposed to each other with an O-ring therebetween. The ferrite chip has a projection. When the input pen is operated, the projection and the ferrite core are moved closer together. When the ferrite chip is moved closer to the ferrite core during operation, the projection is placed substantially close to the ferrite core. Therefore, high responsivity is ensured without moving the ferrite chip into the coil, and there is no need to form an opening or a cavity in the ferrite core.

Abstract: A device for detecting a rotation angle is provided. The device include a first coil, a second coil, and a twist prevention mechanism. The first coil detects a coordinate value. The second coil detects the rotation angle. The second coil includes signal lines extending therefrom. The second coil is rotatable around a center of the first coil without rotating the first coil. The twist prevention mechanism prevents the signal lines from twisting. The device is preferably included in a pack-shaped pointer that operates on a tablet. The pointer and tablet preferably utilize an electromagnetic induction principle to detect the coordinate value and the rotation angle.

Abstract: A stylus for use in a coordinate input system (e.g. digitizer tablet system) includes a finger wheel. The degree of rotation of the finger wheel by the user determines the extent to which a chosen graphical parameter (e.g. line thickness, color, shading, gray scale, etc.) is varied. Thus, a user can easily vary the graphical parameter while drawing by merely rotating the finger wheel about its fixed rotational axis. Preferably, rotation of the wheel causes an intermediate gear wheel with teeth thereon to rotate which in turn causes a potentiometer to detect the degree of rotation of the finger wheel. In alternative embodiments of this invention, a touchpad for inputting finger position and/or finger pressure information may be provided on the side of the stylus instead of the finger wheel.

The pointer is shaped so as to reduce finger/hand fatigue of users manipulating the pointer over and/or across a digitizer tablet. In certain embodiments, an enlarged grip area may flare toward the bottom which helps to prevent the pointer from sliding out of the user's hand. In certain other embodiments, a textured grip area is provided to improve the user's ability to hold onto and control the pointer. In yet further embodiments, a flare is provided near the tip of the pointer in order to reduce the force required by fingers of the user to manipulate and hold the pointer.
