PROBLEM TO BE SOLVED: To surely read printing information of a label discharged from a discharge port of a printer without changing a read position. SOLUTION: The laser scanner 22 is skidded along two long holes 50, 52 to move the laser scanner 22 in parallel in front of the label discharge port 42 and having only to drop a lower side pin 64 down to a hook-shaped hole 54 formed continuously to a front end of the lower long hole 52 can rock an emission direction of the laser scanner 22. Thus, the emission angle of the laser scanner 22 can simply be adjusted without the need for changing a read position P of the laser scanner 22. |
