摘要： The turn-on time of an output transistor is minimized to suppress the average value of the load current, and the load is electrically charged with an intermediate potential prior to outputting data to suppress the instantaneous value of the load current. The output circuit holds the load in an open state when a predetermined reset signal has a first logic level, and drives the load from a high-potential side power source or a low-potential side power source depending on the logic level of the output data when said predetermined reset signal changes to a second logic level, wherein the timing at which the reset signal changes from the first logic to the second logic is delayed at least until the logic level of the output data has settled. Furthermore, the load is driven at an intermediate potential between the high-potential side power source voltage, and the low-potential side power source voltage and is then driven on the high-potential side power source or the low-potential side power source depending on the logic level of the output data.

摘要： An optical deflector is provided with a scanning mirror which is rotatable about a shaft and accompanied by a sleeve and hub. The pneumatic pressure around the mirror which is located within a cavity formed by a motor case of the deflector is maintained lower than an inside pneumatic pressure of a pneumatic pressure creation arrangement. The arrangement has the shaft provided with herringbone grooves engraved on the periphery thereof and the sleeve rotatable about the shaft together with the hub and the scanning mirror. When the scanning mirror rotates about the shaft, windage loss may be reduced, and when the inside pneumatic pressure between the shaft and the sleeve is kept higher than the atmospheric pressure, the rigidity of the shaft may be maintained during the rotation of scanning mirror about the shaft.
