PROBLEM TO BE SOLVED: To stably deliver paper for reducing the possibility of damaging a recording surface of recording paper by a delivery driven roller installing device causing little looseness of a delivery driven roller, and capable of regulating a position and an attitude of the delivery driven roller with high accuracy in an ink jet type recorder. SOLUTION: A bar spring 41 rotatably journals the delivery driven roller 56, and is supported by a first support part 31, and a second support part 33. The delivery driven roller 56 is positionally regulated in the sub-scanning direction Y being the delivery direction of the recording paper P by a second position regulating part 35 constituted by respectively arranging a pair of walls parallel to the bar spring 41 on both sides by sandwiching a spur 11, and is positionally regulated in the direction orthogonal to the sub-scanning direction Y being the delivery direction of the recording paper P by a first position regulating part constituted of eight projection parts 36 in total arranged in the second position regulating part 35.
