Abstract
An information read-out and recording apparatus includes an optical information read-out device for converting optical information into electrical information signals. A serial-input/parallel-output shift register stores information signals from the optical information read-out device and a latch circuit stores information from the shift register for supply to a recording device. The recording device records on a recording medium in accordance with the output of the latch circuit, which parallelly stores the contents of the shift register after a predetermined number of bits of information have been serially stored in the shift register.
Claims159
An information read-out and recording apparatus comprising:
- information read-out means for serially outputting information signals;
- serial-input/parallel-output register means connected to said information read-out means for storing information signals received serially from said information read-out means;
- latch means connected to said register means for storing signals provided in parallel from said register means;
- recording means connected to said latch means for recording on a recording medium in accordance with the output of said latch means;
- and
- control means connected to said information read-out means, said register means, said latch means and said recording means, and having a first control function for providing parallel storage in said latch means of the contents of said register means after a predetermined number of bits of information have been serially stored in said register means and a second control function for providing serial storage in said register means of at least one bit of information during operation of said recording means.
A printing apparatus comprising:
- recording means having a large number of recording elements arranged with a high density for recording in accordance with recording information signals applied thereto;
- latch means connected to said recording means for applying recording information signals to said recording means;
- serial-input/parallel-output register means connected to said latch means for receiving recording information signals in series and supplying recording information signals in parallel to said latch means;
- drive means connected to said recording means and said latch means for generating driving signals to drive said recording means;
- selection means connected to said recording means for generating selection signals to sequentially select and selectively drive plural members of said recording elements;
- and
- clock means connected to said recording means, said latch means, said register means, said drive means and said selection means, for generating clock signals to enter recording information signals into said register means in series;
- wherein while driving signals are generated by said drive means, selection signals are generated by said selection means to sequentially select plural numbers of said recording elements and at least one successive recording information signal is supplied in series to said register means based on the block signals generated by said clock means.
