Abstract: Assuming that a display period for one image is one field, a light source turn on period and a light source turn off period are set for the one field. An overall bending displacement period for making bending displacement of all actuator elements is set within the light source turn off period. A gradational display period for performing substantial gradational display and a reset period for resetting the bending displacement of all of the actuator elements are set within the light source turn on period.

Timing control is performed so that all row selection is completed within each of the subfields. Accordingly, the gradation level is advantageously extended when a relationship of Tr>>Tf is given between a light-emitting rising time Tr of the picture element and a quenching falling time Tf of the picture element.

Abstract: A handwritten data input device has a coordinate detection tablet for detecting writing data input by handwriting using an input pen and a program storage medium. When a predetermined preprocess is required for an input process to accept writing data input by handwriting from the tablet, useless handwritten input can be effectively avoided when the preprocess has not been completed. In the handwritten data input device, a CPU determines whether the preprocess has been completed when the input pen approaches the tablet and, if the preprocess has not been completed, drives a buzzer to generate an alarm tone, thereby notifying the operator that the handwritten input is invalid in advance.

Abstract: Disclosed is an input device in which a control member is molded by injecting a liquid synthetic resin from an inlet of a mold formed at a position corresponding to the top of a control portion. The inlet is positioned at about the center of the control member, and the synthetic resin flows from the control portion having a relatively large thickness to beam portions and base portions that have a relatively small thickness. This allows smooth flow of the synthetic resin, and ensures consistently high quality and high precision of the control member. Moreover, fiber orientation is made uniform in the beam portions and the base portions, which gives good bending characteristics to the beam portions.
