Filed: 1991-03-01
Abstract: PURPOSE:To obtain an even irradiating energy over the whole recording surface to be initialized and to facilitate proper initialization by initializing while relatively vibrating an initializing light beam in the direction of its parallel displacement. CONSTITUTION:From an AC signal generating circuit 11, an AC signal (e) is supplied to one input terminal of a resultant circuit 12. To the other input terminal of the circuit 12, a carrier signal E from a DC power source 8 is supplied. In the circuit 12, the signal (e) is superimposed on the signal E and the resultant signal E+(e) is supplied to a carrier motor 5. Accordingly, a transfer stage 4 is transported vibratingly in the X direction, and a beam spot S is relatively moved vibrating to the X direction, i.e., the direction of the diameter of a disk 1. By this vibration of the spot S, the trough part under the irradiating energy is also irradiated in superposition with the central part which is the strong part of the irradiating energy or the spot S.

Filed: 1987-02-19
Abstract: PURPOSE:To improve an operability by providing a retrieval control means and outputting the same output as the case corresponding information is present in an information memory at the time of outputting character string data in a data buffer to a printing medium. CONSTITUTION:The inputted character data string is stored in the data buffer and outputted to an output medium by a buffer output means. At the time of retrieving the information memory by a retrieving means on the outputted character data string, the retrieving means is controlled so as to constantly output the same output as the case the information is present even when the corresponding information is not present in the information memory by the retrieval control means. Thereby, for instance, in a spelling check mode, at the time of copying and printing a word, when the word is not stored in a dictionary memory or a user dictionary memory, even if the word is a misspelled word, it is not alarmed by a buzzer, so that an input operation or an edition operation can be smoothly carried out without an interference by the buzzer at every time.
