摘要:
A coordinate input apparatus determines the coordinates of contact of a vibration pen with a vibration transmission plate by detecting vibrations from the pen through a vibration sensor. Constants required for measurement are generated in a constant determination circuit on the basis of vibration cycle measurements and a circuit measures the cycle of the detected vibrations from the vibration sensor using the determined constants. Automatic determination of constants eliminates inaccuracies due to component variations and reduces production costs and maintenance.

A coordinate inputting device in which the vibrations imparted from a vibration pen to a vibration transmitting plate are detected by a plurality of vibration sensors so as to enable the coordinates of a vibration input point to be detected using the time it takes for the vibrations to propagate on the vibration transmitting plate. The vibration transmitting plate has noise interrupting means for preventing noise coexistent with the vibrations imparted by the vibration pair for coordinate detection from being input to the vibration sensor.

The present invention relates to a character input apparatus and method which pairs the title of a heading to the region where a character is inputted and determines the character group which can be inputted into the region corresponding to the heading as input candidate characters. When a character is inputted in the region, the heading in that region is discriminated and the characters are recognized referring to the input candidate character group corresponding to the title of the heading.

A vibrating input pen used for a coordinate input apparatus for detecting a coordinate of an input position of a vibration by detecting the vibration input from the vibrating input pen to a vibration transmitting plate includes a vibration generating element for generating a vibration and a horn member forming a pen point of the vibrating input pen for transmitting the vibration generated from the vibration generating element. A positioning member positions the vibration generating element in relation to the horn member so that the direction of vibration of the vibration generating element coincides with the direction of vibration of the horn member and the axis of the vibration generating element coincides with the axis of the horn member.

A transfer recording medium comprises a transfer recording layer, which causes an irreversible change in transfer characteristic when provided with plural kinds of energies, at least one of which is applied imagewise, to provide a transferable portion or latent image portion in the transfer recording layer. The transferable portion is then transferred to a medium such as plain paper to form a transferred image thereon, which is then fixed by application of at least one of light, heat and pressure. The fixing step is effective, e.g., in providing a recorded image with improved stability against environments and elapse of time, color reproducibility and color densities through functional separation from the transfer step.

A vibration which is input to a vibration propagating plate by a vibration pen is detected by vibration sensors attached at corner positions of the plate. This vibration is propagated as elastic waves in the vibration propagating plate and reaches the sensors. The coordinates of the vibration input point are calculated on the basis of the vibration propagating times corresponding to the detection signals from the sensors. The vibration sensors are come into pressure contact with the vibration propagating plate through a fluid like a grease having a high viscosity or consistency. Since such a fluid is filled in the space which is formed between the pressure contacting surfaces of the vibrator and vibration propagating plate, their coupling states are stable and the vibration and coordinates detecting characteristics can be uniformed every product.
