1. What Is the OCR Sensor CVS4 Series?
zThis is a sensor that can use its built-in OCR (Optical Character Reader) to read alphabet characters,
numeric values, and symbols. (Other characters cannot be read.)
Date marking (the time is also
Date + character string marking
possible)
(For example, best before dates and
(For example, best before dates)
manufacturing plant identification marks)
2006.03
06.03.14 / AB1
Readable characters/symbols
Characters/symbols that become readable after
registration in the expansion dictionary
* You can use [View NG Log] (see P.5) on the top menu to register NG characters in the expansion dictionary.
* To edit the expansion dictionary, you require the PC communication cable CVS-C2C (standard price: 10,000 yen). You have to
use the setup software (which can be downloaded free of charge from the Optex FA website: www.optex-fa.com).
zThe read characters are compared against the sensor's built-in dictionary data, and the closest characters
are selected. You can configure the sensor so that the judgment is OK if all the selected characters are
correct and NG if even one character does not match.
Correct marking:
OK
Marking mistake:
2006.03
2006.04
zThe judgment is OK if a small part of the character is missing such that the character can still be read by
the human eye.
Correct marking:
OK
Small part of the character missing:
2006.03
2006.03
zUpdating of date marking is also supported automatically.
The
built-in calendar function
automatically handles updates to the dates and times that are marked by a
printer. There is no need to reconfigure the settings each time that the printed details change.
Also, you can set the date tolerance, which makes it possible to prevent erroneous judgments from
occurring when the date changes.
Character string marking
(For example, lot numbers and part
numbers)
AA0054321
0 to 9, A to Z, ., /, :
!, #, $, %, &, (, ), *, +, ;, <, =, >, ?, @, [, \, ], ^, `, a to z, ˜
NG
Missing character:
NG
200 .03
OK
Large part of the character missing:
2006.03
