PROBLEM TO BE SOLVED: To stabilize a posture around an axis Z of a carriage 5 supported slidably astride a first guide member 22 and a second guide member 23 on a plate. SOLUTION: A third sliding face 54 erected to be orthogonal is prepared to be located between a first sliding face 51 and a second sliding face 52 in a direction of an axis Y. A pair of right and left third sliding projections 60a and 60b slidable in contact with the third sliding face 54, and a holding body 62 as an elastic member for elastically exciting fourth sliding projections 65a and 65b opposed to the third sliding projections 60a and 60b via the third sliding face 54 (guide strip 23c) into a direction of the third sliding face 54 are set at the carriage 5. A belt link part 63 is located between a second sliding projection 55a and the third sliding projections 60a, 60b in the axis Y. Accordingly, posture change of the carriage 5 about the axis Z is eliminated, and stable movement in a main scanning direction (direction of an axis X) can be secured. COPYRIGHT: (C)2007,JPO&INPIT |
