DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an image data processing apparatus whose main body can be manually moved to read image information from an original and/or to print information.
BACKGROUND ART
Japanese Patent Disclosure No. 55-115773 discloses a "manual sweeping copier" whose main body is manually moved, thus to read image information from an original and/or to print information.
The manual sweeping copier has an encoder. The encoder detects the distance the main body of the copier has been moved, and produces encoder pulses. Information is read and printed in synchronism with the encoder pulses.
Since the main body of such a manual sweeping apparatus is moved by hand, it is difficult to move the main body at a constant speed. There is a possibility that the main body is moved at a speed above the optimum value for reading information or printing information.
With a manual sweeping, image data processing apparatus of the type described above, it is difficult to achieve a high-quality reading of information and a high-quality printing of information. There is the possibility that errors are made in reading or printing information.
TECHNICAL SUBJECT
It is an object of the present invention to provide an apparatus which can inform an operator whether or not the operator is moving the main body of the apparatus at a speed suitable for reading information or printing information.
Another object of the invention is to provide an apparatus which enables an operator to move its main body at a constant speed.
To attain these objects, according to the invention, there is provided a manual sweeping, image data processing apparatus which comprises:
a housing small enough to be held in a hand and moved;
image data processing means provided within the housing, for reading information from an original while the housing is being moved in contact with the original, and/or printing information on a sheet of recording paper while the housing is being moved in contact with the recording paper;
distance detecting means for detecting the distance for which the housing has been moved relative to the original or the recording paper while in contact with the original or the recording paper;
control means for controlling the image data processing operation being achieved by the image data processing means, in accordance with the data output by the distance detecting means; and
indicating means for indicating a specific item of information on the basis of the data output by the distance detecting means.
The manual sweeping, image data processing apparatus of the present invention can, therefore, be moved at a speed suitable for reading or printing information, and can be moved at a constant speed. Since the apparatus can be moved at a constant speed, the possibility that errors occur during the reading or printing of information is very greatly reduced. Further, since the moving speed of the apparatus is not unstable, the apparatus can accomplish a high-quality reading of information and a high-quality printing of information.
