Handheld data input apparatus
First Claim
1. A handheld data input apparatus comprising:
- a pressure-sensitive tablet;
a character recognition means for recognizing handwritten character data input through said tablet;
a document memory, connected to said character recognition means, for storing a recognition result from said character recognition means;
a power supply for supplying power to said tablet, said character recognition means, and said document memory; and
a casing integrally incorporated said tablet, said character recognition means, said document memory, and said power supply; and
wherein said handheld data input apparatus is arranged to be connected to a document data processing apparatus main body via an external interface means, and when said handheld data input apparatus is connected to said document data processing apparatus main body, said character recognition means can supply document data from said document memory to said document data processing apparatus main body.

Abstract
In the data input apparatus, a pressure-sensitive tablet, a character recognition section for recognizing handwritten character data input through the tablet, a document memory for sequentially storing a recognition result of the character data, and a power supply for driving the tablet, the recognition control section, and the document memory, are integrally incorporated in a handheld casing. The data input apparatus can be detachabably connected to a document processing apparatus main body via a cable. During an input operation, the data input apparatus is disconnected from the data processing apparatus main body, and performs the input operation independently of the main body, to store the input document data in the document memory. The data input apparatus is connected to the document data processing apparatus, and the document data stored in the document memory is sent to the main body to be processed.
