Abstract
An improvement in movement of the recording section in a recording apparatus such as a typewriter, a printer or the like is provided. This recording apparatus comprises: a print ribbon cassette having a recording material; a carriage having a solenoid or a cam for moving the cassette; a detector for detecting the vertical or horizontal moving amount of the cassette; and a controller for controlling the moving condition of the cassette moved by the carriage on the basis of an output from the detector. The moving time of the ribbon cassette is changed in accordance with the typing speed of the operator or the size of character to be recorded. Thus, the whole printing time can be shortened and the noise generated in association with the typing operation can be reduced.
