Title: Method and device for data read
Inventor: TAKEDA TADAO
IPC: G06K19/06
Filed: 1984-03-30
Abstract: PURPOSE:To detect easily the error of scanning due to manual operation of a bar code reader by arrangement of start and stop characters. CONSTITUTION:In the first line, a character (a) is arranged as the start character and a stop character (b) is arranged in the end of the line. In the second line, the character (b) is used as the start character and a character (c) is used as the stop character. Hereafter, characters (b), (c), and (d) are used as start and stop characters repeatedly similarly. One character 1a of the bar code is read when the bar code reader is scanned, and the control is advanced to the next step by YES because the character 1a is a control character, and a read flag is checked. In the next step, YES is attained because the first read character 1a coincides with the character (a) inputted first to a control register. If the second line is scanned erroneously, the first head character does not coincide with the character in the control register because the first character 2a of the second line is (b), and the control is advanced to ON, and an error is displayed on a display device 13 and an error tone is sounded by a buzzer 14 in a step S11.
