摘要： In image formation, a reversible thermosensitive medium, preferably in the form of an endless belt, is selectively heated in accordance with an electrical image signal, so that the areas of the thermosensitive belt will have different transmittances corresponding to the respective pixels of the image signal. A photosensitive member, preferably in the form of a drum, widely employed in electrophotography, is uniformly charged, and the thermosensitive belt is then superimposed on the photosensitive drum, and the photosensitive drum is exposed to light of a uniform intensity through the thermosensitive belt. The intensity of light which each area of the photosensitive drum receives depends of the transmittance of the corresponding area of the thermosensitive belt. An electrostatic image that is formed on the photosensitive drum as a result of the exposure is therefore a conversion from the transmittance image on the thermosensitive belt. A toner image may then be developed and transferred and fixed on recording paper.

摘要： A coordinate-capturing apparatus suitable for inputting handwritten characters or diagrams to a computer or a printer is disclosed. The apparatus includes an ultrasonic transmitter mounted on an input pen for transmitting ultrasonic waves, two ultrasonic receivers for receiving ultrasonic waves transmitted form the ultrasonic transmitter, and a distance calculating device for calculating distances between the input pen and the two ultrasonic receivers in order to determine coordinates representing a position of the input pen on the basis of the calculated distances. The apparatus of the invention can perform coordinate detection smoothly even when the input pen moves fast, and has reduced electric power consumption in the input pen to increase the life-span of a battery included in the input pen.
