PURPOSE:To form a hard copy without slipping off of color only with one CRT by disposing movably a lens system in a sub-scan direction intersecting orthogonally with the optical axis direction of an emitting light beam and generating sequentially said beams about each line of a picture signal in correspondence to the movement of the lens system. CONSTITUTION:The CRT 27 arrays R, G and B phosphors on a phase plate 28 so that strips 29R, 29G and 29B can be parallel. A television (picture) signal is inputted to the CRT 27 in such a way that the R, G and B delayed in time- sequentially by n-numbers are switched by the line. A control pulse to a stepping motor 25 is supplied at every pair of R, G and B. As a result the lens 24 is moved by one line on a film in the sub-scan direction wherever one line of R, G and B each are sequentially recorded. Thus R, G and B picture signals having the same line number are recorded at the same position on the film 26, thereby obtaining the hard copy with a suitable color registration. |
