Title: Checking method for split dot pattern
Inventor: KOMINATO MOTOYUKI
IPC: G06K15/10
Filed: 1978-11-20
Abstract: PURPOSE: To simplify a check circuit by making a check at a fixed position even if a dot pattern would by divided by random size.  
     CONSTITUTION: One screen is divided into four, check bits 11W14 are added to heads of respective dot patterns, and end bits 21W24 are also added to tails. Each check bit, representing the number of "1" or "0" dots in each divided dot pattern, is used to check the number of "0" or "1" dots and that of all dots in the dot pattern when a corresponding end bit is detected. As a result, a connection among freely- divided dot patterns can be checked. In this case, check bit and end bits are never displayed by a display unit. This constitution simplifies a circuit making the check and transmitted dot pattern information can easily be checked.
