<P>PROBLEM TO BE SOLVED: To solve such a problem that the position of an end of a paper sheet cannot be corrected according to the degree of degradation of a light receiving part of a liquid jetting device to be individually used by users. <P>SOLUTION: The liquid jetting device includes a carriage reciprocating in the moving direction across the conveying direction, a support part for supporting a paper sheet, a light emission part 32 and a light receiving part 33 provided on the support part side of the carriage, an end position detection part 24 for detecting the end of the paper sheet, a flat part provided at the position opposed to the emission part 32 and the light receiving part 33 by the movement of the carriage and having a reflection surface that can reflect the light applied from the light emission part 32, a nonvolatile memory 23 as a storage part storing the output voltage and the positional deviation, and an end position correction part 25 which receives the reflected light from the reflection surface by the light receiving part 33, obtains the second output voltage output from the light receiving part 33, and corrects the position of the end of the paper sheet based on the positional deviation corresponding to the second output voltage. <P>COPYRIGHT: (C)2013,JPO&INPIT |
