Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent the contamination of a linear encoder sheet caused by ink mist. SOLUTION: At least, a carriage 1, the linear encoder sheet 6 having a counter for detecting the position of the carriage 1, and an encoder sensor 7 are arranged in a space container 11. Fans 14-1 and 14-2 being an inner pressure adjusting means for adjusting the inner pressure of the space container 11 are provided in the exterior member of the space container 11, so that at least pressure in the space container is not made into a negative pressure state.
