Abstract: The present invention relates to a device for supplying and recovering printed material used in digital printing with which a long printed material can be simply mounted onto a digital printing apparatus so that the work efficiency of an operator can be improved. The present invention includes: a supply roll around which the printed material is wound; a first transport roll which transports the printed material supplied from the supply roll to the lower part of a head part; a second transport roll which discharges the printed material on which printing is completed by the head part; and a recovery roll which has an axis of rotation parallel to the axis of rotation of the supply roll and which is rotated by a recovery driving means so that the printed material discharged from the second transport roll is wound. The printed material is supplied when one end thereof is unwound from the supply roll and is fixed to the recovery roll through the upper sides of the first transport roll and the second transport roll.

Abstract: Disclosed is a head alignment assembly in which a deviation of the head can be aligned conveniently with simple operation from the outside of the printer head section. The head alignment assembly includes a base plate to which at least one head unit is fixed to be exposed downward by a first head support block and a second head support block; a first fine adjustment section configured to shift the first head support block in a longitudinal direction of the head unit; and a second fine adjustment section configured to shift the second head support block in a transverse direction orthogonal to the longitudinal direction of the head unit. The first fine adjustment section includes a first push rod supported by fixed guides which are fixed on the base plate to press the first head support block; and a first handle fixed to one end of the first push rod to move the first push rod in the longitudinal direction.
