Abstract

PURPOSE:To mask an original form in a simple way and to realize a selective reading input by putting the original form on the surface of a magnet and attracting the magnet and a masking member sandwiching the original form. CONSTITUTION:An original form 12 is set onto an original form fixing stage 6. In other words, a stepped part is secured between a magnet 30 and a groove 35 and the edge of the form 12 is set at the position of the stepped part. Then a magnetic opaque thin plate 20 of a color approximate to that of the form 12 is put on an undesired character for input and attracted by the magnet 30 via the form 12. Thus the form 12 is masked. Then a self-traveling action is given over the stage 6 where the form 12 is set and the written contents are optically read. Thus data are sent to a word processor. In such constitution, the form 12 containing many written characters, symbols, etc., can be partly masked in a simple way and a selective reading input is possible.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reading device for handwritten characters, etc. in a Japanese document processing device such as a word processor, and particularly to a manuscript for selectively reading and inputting written characters. Concerning paper masking methods.

[Conventional technology]

In word processors, as a method of registering and utilizing characters and symbols other than the standard Mincho font, it is conventional to specify black and white for each of the 24 x 24 dots that form one character and input them from the keyboard. , your favorite character,
Methods for creating symbols and the like are known.

[Problem that the invention seeks to solve]

According to the above-mentioned conventional technology, it takes a lot of time to create one character and is extremely troublesome, so it is not suitable for inputting a large number of characters, and the storage capacity is small. It has been impossible to create personal documents such as letters and invitations entirely in the person's own handwriting and enjoy the taste of handwritten characters, except by registering and using company emblems and the like.

In order to improve the problem of the above-mentioned conventional technology, which is unsuitable for inputting a large number of characters, it is possible to write a large number of characters in a desired font on one sheet of standardized manuscript paper, and then This problem can be solved by using a method in which the manuscript paper is read at one time by a reading device.

However, if you write a large number of characters on one sheet of paper at the same time, you may end up forgetting one or two characters, writing them outside the designated frame, or conversely writing them too small, or because you don't like the font. Characters that you don't want to appear will appear. In particular, as the number of characters written on one sheet increases, the probability that satisfactory characters can be written on all the manuscript sheets decreases. For example, if you can write up to 400 characters on a single sheet of manuscript paper, you will most likely end up writing one or two characters that you don't like.

In this case, if you have written on the manuscript paper with a pencil, it is possible to correct it by erasing it with an eraser, but if you are correcting just one character, for example, if you move the eraser a little too much, the adjacent characters on the top, bottom, left and right sides that you do not want to erase will be erased. You may end up erasing the edges, or if the surface of the eraser is black and dirty,
There is also the risk that the manuscript paper will be stained black and noise will be read. The larger the number of characters that can be written on a single sheet of manuscript paper, the smaller the character size becomes, making it difficult to use an eraser.

An object of the present invention is to perform selective reading by masking the manuscript paper in a simple manner when a large number of characters are written on one manuscript paper and read and input at one time by a reading device. The purpose is to enable input.

[Means for solving problems]

The above purpose is to create a structure in which when a manuscript paper with written characters etc. is set in the reading device, the manuscript paper comes into contact with the top surface of a plate-shaped magnet, and various types of paper are placed on the top surface of the magnet with the manuscript paper in between. This is achieved by attaching a thin plate of opaque magnetic material, which has a similar shape to the original paper, and masks the characters that are not desired to be input.

[Effect]

The above manuscript paper is fixed to 1 by the manuscript paper fixing means of the reading device.
It is set so that it touches the upper surface of a plate-shaped magnet with the side on which characters are written upward, and is optically read by a reading means from above after passing through the magnet. The thin plate used to mask characters that you do not want to input should be a square, rectangle, or any combination of these, each having a size that is an integral multiple of the fold size of one character on the manuscript paper. A shape is available, and masking can be performed by blocking light between the reading means and the manuscript paper for each fold of the manuscript paper.
