摘要： PURPOSE:To prevent deterioration of the printing density when an image is enlarged by providing a standard printing mode whereby a paper is fed at normal speeds to print printing data and an extended printing mode whereby said paper is fed at speeds higher than by said standard printing mode, so that the same printing data is overlapped on the adjacent two lines according to said extended printing mode. CONSTITUTION:In a standard paper-feed mode, first, fourth, seventh,... timing pulses SP are used to rewrite the content of a line memory 2 and print on line. On the other hand, in an extended paper-feed mode, first, fifth, ninth,... timing pulses SP are used to rewrite the content of the line memory to print the one line. It is so controlled according to the extended paper-feed mode that every content of the line memory 2 is read two times. Therefore, the paper is fed at higher speeds for one line. When an image screen '3:4' is converted to an image screen '1:1', since the adjacent lines are printed by the same printing data at the part of the image screen where a circle with some density exists, the gradation of this part is never reduced.

摘要： PURPOSE:To keep the continuity between lines and to restrict the difference with the objective printing result of a printer to the min. by calculating the cumulation of correction quantity at every line feeding and judging whether the cumulation result is subtracted from line feed quantity and generating the line feed quantity to which subtraction correction is applied if necessary. CONSTITUTION:When a line feed order is outputted, the line feed quantity data from a line feed quantity indication means 1 is inputted to a line feed quantity correction means 2. When the correction of line feed quantity is necessary, the line feed quantity correction means 2 generates the correction quantity calculated from line feed quantity data and line feed quantity to which the correction quantity is added on the basis of the data from a printing data memory means 6 to transmit the same to a correction quantity cumulation means 3 and a line feed means 5. The correction quantity cumulation means 3 adds the inputted correction quantity to the total to transfer control to the line feed means 5. When the line feed quantity correction means 2 judges that correction is unnecessary, a correction negating means 4 refers to the data of the printing data memory means 6 and the cumulation result of the correction quantity cumulation means 3 to subtract the cumulated quantity from indicated line feed quantity and transmits the same to the line feed means 5 as execution line feed quantity to transfer control. The line feed means 5 executes line feed on the basis of the execution line feed quantity data.

摘要： PURPOSE:To enable broken lines to be drawn with matched vertical continuation through expanding broken-line data as graphic image data in processing input data permitting arbitrary designation of line pitch at the time of using a system capable of superposing printing of characters and graphic images but not having a ruled line complementing function, by providing a line kind discriminating means, a reference start position calculating means, and an image expanding means. CONSTITUTION:An input file 1 of a SYSOUT type and a format definition file 2 are read, and it is judged by a line kind discriminating means 3 whether given data is a broken line. When the data is not a broken line, the data is expanded by a character expanding means 6, and is outputted as character data to an output file 7. When the given data is a broken line, the kind of the line is discriminated, and on the assumption that successive broken lines are drawn by use of a font pattern conforming to the kind of the line, a position in font pattern data for the broken line at which reference should be started is calculated by a reference start position calculating means 4. Then, an image expanding process is carried out by an image expanding means 5, and the result data is outputted as graphic image data to the output file 7.

摘要： PURPOSE:To enable accurate minute feeding of a printing paper and print two- pass-printed characters with favorable printing quality, by providing a first phase-exciting signal-generating means for generating a phase-exciting signal by a two-phase excitation system, and a second phase-exciting signal-generating means for sequentially generating phase-exciting signals corresponding respectively to a (N+2) phase and a (N+2, N+3) phase when a stopping phase is a (N, N+1) phase. CONSTITUTION:A paper feed request signal-discriminating means 21 receives a paper feed request signal inputted externally, and when the signal is for a normal paper-feeding mode, a first phase-exciting signal-generating means 22 is started. When the signal is for a minute paper feeding mode, a second phase-exciting signal-generating means 22 is started. When a stopping phase is a (N, N+1) phase, in the minute paper feeding mode, the second signal- generating means 23 sequentially generates phase-exciting signals corresponding to a (N+2) phase and a (N+2, N+3) phase. In the case of minute paper feeding starting from the condition where a motor 2 is stopped by exciting excitation phases 2-1, 2-2, only an excitation phase 2-3 is excited, and then excitation phases 2-3 and 2-4 are excited to drive a paper-feeding mechanism.

摘要： PURPOSE:To correctly feed a printing position to the next reference line position even upon the appearance of a return code in the condition where the printing position is deviated upward or downward from a reference line position and enable the operator to type constantly without worrying about the deviation of the printing position from the reference line position, by providing a means for storing an upward or downward movement of the printing position from a standard line when such a movement is performed. CONSTITUTION:When a printing position is moved upward or downward from a reference line by a line-feeding means M1, the movement is stored in a storage means M3. The information stored in the means M3 may be a plus or minus moving quantity. Even where the printing position is once deviated from a reference line due to an upward or downward movement, when the printing position is thereafter returned to the reference position by the line-feeding means M1, information indicating 'no movement' is stored into the storage means M3. When a return code appears, a return- controlling means M2 causes the line-feeding means M1 to perform a line feed of the printing position, and returns the printing position to a predetermined left margin position. In this case, a correcting means M4 corrects the line feed effected by the return-controlling means M2, according to the information stored in the storage means M3.

摘要： PURPOSE:To enable a line feeding operation with a minute line feed pitch equal to 1/2 of a normal line feed pitch to be performed with a pulse motor having the same performance as that of a conventional one and ensure that maintenance of a driving torque and the period of time required for a continuous line feeding operation are the same as those in a conventional system, by a method wherein when the final stop position is associated with the minute line feed pitch, a line feeding operation is conducted with two-phase excitation up to the pitch preceding the minute line feed pitch (final pitch), and performing one-phase excitation for the final pitch while increasing a torque maintained during the one-phase excitation. CONSTITUTION:In a line feeding operation, when the phase of a pulse motor at the end of line feeding is to be stopped at the position of 2n+1/360'', the motor is driven by two phase excitation during deceleration (a), and at the position (e) of two-phase excitation preceding the phase in which the motor is to be stopped, two phase excitation is conducted (n) times at a period T1, thereby stabilizing the operation. Thereafter, excitation in the stopping phase is performed N times at a period T0, and the motor it stopped at the position of 2n+1/360''. Since the stopping phase is one phase, a torque being maintained is lowered. In consideration of this, the ON time of a switching transistor Tr6 in a driving circuit 13 in the case of stopping with one-phase excitation is set to be longer than that in the case of stopping with two phase excitation.

摘要： PURPOSE:To improve the precision of line feed by providing a switch means for adding a minute quantity to or subtracting the same from a line feed value stored in a memory, and another memory storing the line feed value subjected to addition or subtraction, and by determining the quantity of line feed on the basis of a value of the other memory. CONSTITUTION:The quantity of fine adjustment of line feed is set. Test printing for setting the quantity of fine adjustment of line feed is started, and MPU 5 reads a set value of DIP SW 6 and adds an offset value corresponding to the read set value to a line feed value of a memory 7a. The value thus obtained is stored in a memory 7b, an appropriate pattern is recorded in one line, a pulse motor 9 is driven by the value (number of pulses) of the memory 7b to execute line feed, and recording is conducted another line. In the case when overlap, blank or the like is found in a joint of the recorded pattern due to the line feed, the operation conducted thereto fore is repeated, and when the overlap or the like is not found, the fine adjustment of the quantity of line feed ends.
