Title: Original masking method for reader of handwritten character or the like
Inventor: KIMURA MASAHIRO
IPC: G06K9/20
Filed: 1987-06-01
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.

IPC: G02B6/24
Filed: 1979-10-22
Abstract: PURPOSE:To considerably improve workability by closely adhering plastic sheets with heating to plural core units from both sides. CONSTITUTION:This is a method of stripping the sheaths at the end part of a communication cable, branching the same to plural core units 1a, and forming insulation sheaths on every core unit 1a.
