    摘要: A main control unit for controlling a dot printing element in a laser beam printer has a first control means for controlling the dot printing element so as to print a predetermined dot size in accordance with an existence of a dot signal in an image information signal. The main control unit has a second control means and a control selection means. The second control means controls the dot printing element so as to vary a size of the dot of a dither matrix. The control selection means operates selectively the first control means and the second control means. A gradation data is transmitted to the printer without conversion of a dither matrix data. The printer can print an image in response to in either cases of a character pattern dot data signal and a gradation data signal. The printer has a gradation signal on an interference, a gradation converting means and a laser modulating means. The printer can connect in either cases of an existence state and a non-existence state of the gradation signal.

    摘要: An apparatus for processing a binary video signal carrying information of dots to be printed. The binary video signal is at a relatively higher or lower level for the whole of each bit time to constitute a unit portion of the binary video signal. The unit portion of the binary video signal at one of the levels is representative of one dot. The apparatus includes a first detector for detecting a start of a length of each of those parts of the binary video signal which are at the one level, a second detector connected with the first detector for determining the number of unit portions contained in each part of the video signal, a generator connected with the second detector for producing one or more dot pulses for each part of the video signal, each of the dot pulses having a pulse width smaller than that corresponding to the bit time, the number of the one dot pulses being the same as that of the determined number of unit portions, and a controller connected with the generator for controllably adjusting the pulse width of the dot pulses.

    摘要: In a serial thermal transfer printer or serial thermal printer comprising; a thermal head having a plurality of heat elements arrayed in a line; and means for selectively energizing and driving the plurality of heat elements in synchronous relation with the relative movement between the thermal head and the ink ribbon or heat sensitive paper, wherein when printing dots are successively positioned in the direction of the relative movement between the thermal head and the ink ribbon or heat sensitive paper, printing timing of the last dot is set ahead so as to be earlier than normal printing timing. When the previous printing data is "1" (recording) and the subsequent printing data is "0" (not recording), the position of the present printed dot is shifted toward the previous printed dot to compress the entire width in case of two or more successive dots. Since the printing head is traveling continuously during printing, the position of the present printed dot can be shifted toward the previous printed dot by advancing the printing timing. If the previous printing data is "0" and subsequent printing data is "1", it is apparent that a similar effect can be obtained by setting the printing timing backward so as to shift the position of the present printed dot toward the subsequent printed dot.
