Abstract
In processing a target sheet, raised letters (Braille) are formed by selectively driving a plurality of embossing pins arrayed in a direction perpendicular to a direction of feeding the target sheet such that the raised letters are represented in a projected bit pattern which is embossed at embossing points of a plurality of stages in two rows. Embossing operation is performed on the target sheet based on the emboss-inspection pattern which is made up of a repetition of the bit pattern. This emboss-inspection pattern facilitates to identify the cause of troubles, if any, in the embossing system.
Claims9
An apparatus for processing a target sheet comprising:
- embossing means for embossing raised letters on the target sheet to be fed, said raised letters being formed by selectively driving a plurality of embossing pins arrayed in a direction perpendicular to a direction of feeding the target sheet such that the raised letters are represented in a projected bit pattern which is embossed at embossing points of a plurality of stages in two rows;
- emboss-inspection mode setting means for setting an emboss-inspection mode in which inspection is made whether an embossing operation for forming the raised letters is normal or not;
- emboss-inspection pattern storing means for storing an emboss-inspection pattern which is made up of a repetition of a predetermined bit pattern;
- and
- control means for controlling said embossing means to perform embossing operation based on the emboss-inspection pattern when the emboss-inspection mode is set.
A method of controlling embossing by an apparatus for processing a target sheet in which raised letters are formed by selectively driving a plurality of embossing pins arrayed in a direction perpendicular to a direction of feeding the target sheet such that the raised letters are represented in a projected bit pattern which is embossed at embossing points of a plurality of stages in two rows, comprising:
- setting an emboss-inspection mode and determining whether an embossing operation is normal or not by controlling an embossing means to perform an embossing operation based on an emboss-inspection pattern which is made up of a repetition of the bit pattern.
