PROBLEM TO BE SOLVED: To realize a precise scan operation and eliminate a disorder such as a wavy line of a recorded image which should otherwise be linear by precisely moving a mobile table shuttling back and forth with a mounted recording head constantly in a linear direction along a pair of guide rails, without any additional new member or mechanism. SOLUTION: A mobile table 2 is supported and guided, in a scannable manner, by a pair of guide rails 3a, 3b with an angular cross section and a circular cross section. In addition, a shaft member 2d protruded obliquely from an orthogonal direction with a scanning direction is provided on the mobile table 2. Further, a wheel 2b rolling along the upper surface of the guide rail member 3a with an angular cross section, is mounted on a shaft member 2d in freely rotatable manner. |
