Abstract

PURPOSE:To surely and easily exchange recording paper without causing paper jamming, improper paper feeding, etc., by providing a housing, a plurality of drums, cartridges, and recording means. CONSTITUTION:A cartridge 14 to which a roll of recording paper 12 is loaded beforehand, is set in a main body 1. When a drum 11 is rotated by rotationally driving a gear plate 11a by means of a motor 15, the recording paper 12 is fed from a drum 10 and data are recorded on the paper 12 in a pen section 8. The recorded paper 12 is wound around the drum 11. Since a sprocket 13 always detects the feeding speed of the paper 12 and a control means 16 always controls the motor 15 by processing the information detected by the sprocket 13, the feeding speed of the paper 12 is always maintained at a prescribed value. Since the recording paper 12 can be exchanged by exchanging the cartridge 14 only, the paper 12 can be easily and surely exchanged without causing such a trouble as the jamming, improper feeding, etc., of the paper 12.
