- the printing head As well as the bit stored in the printing position register 14, advances to the right, then the position of said bit in the printing position register 14 and that of the foremost one of a plurality of bits stored in the tabset control register 15 coincide with each other.
- the AND circuit 45 produces an output signal to reset the flip-flop circuit 38, thereby stopping the rightward advance of the printing head and the rightward shifting in the printing position register 14.
- the printing head is set at the foremost one of the bits (FIG. 4D) stored in the tabset control register 15, namely, at the point where the first digit 1 of the numerical data 145 is to be printed.
- the position of the bit stored in the printing position register 14 at this time is indicated in FIG. 4E.

- the AND circuit 33 is gated by the signal II, a signal instructing the printing of the first digit 1 is delivered to the printing section 12, causing the printing control circuit 36 gives forth an output signal IV, which in turn is deliveredto the AND circuits 41 and 42.
- the holding circuit43 produces an output signal of 0 and the AND circuit 41 gives forth an output signal S13 by the action of the inverter 44, causing the printing con.- trol circuit 36 to generate output signals II, III and IV again in succession.
- the signal II is delivered to the AND circuit 33, then a signal denoting the second digit 4 of the input data of is supplied to the printing section 12, causing the digit 4 to be printed immediately after the previously impressed digit 1.
- the bit stored in the printing position register 14 also advances rightward similarly for a distance of one order as shown in FIG. 46. Since, under this condition, coincidence does not take place between the position of the bit stored in the tabset register 13 and that of the bit stored in the printing position register 14, the printing control.

- the last digit 5 of the input data 145 already storedin the foremost order readout circuit 32 is drawn outby the signal II for printing.
- the signal III further shifts the printing head by one order, causing the bit stored in the printing position register 14 to be brought to the position indicated in FIG.
- the AND circuit 30 produces an output signal of 0, the data stored in the tabset control register 15 is extinguished and the gate of the AND circuit 26 is opened to cause a signal denotingthe tabset position 30 following the tabset position 20 (said tabset position 30 represents the lower order tabset position of the second column C2 of FIG. 4.) to be written in the tabset control register 15 (FIG. 41), thus providing a condition ready for printing in the second column C2.
- the first output signal S9 from the discriminator 16 is in the state of I.
- the printing control circuit 36 produces a signal I, which effects the one-order rightward advance of the printing head, as well as of the bit registered in the printing position register 14. Since the flip-flop circuit 38 is not set as described above, the printing head is made to advance only for a distance of one order but not continuously.
- the printing control circuit 36 Upon the one-order shift of the printing head, the printing control circuit 36 generates an output II which causes the character A of the foremost order read out from the buffer register 11 by the foremost order readout circuit 32 to be printed. Thereafter, upon receipt of an output signal III, the printing head further advances rightward by one order.
- the printing control circuit 36 produces an output signal IV; the holding circuit 43 generates an output signal of 0. Consequently said printing control circuit 36 gives forth again an output signal II to cause the character S to be printed immediately after the character A. Printing is thus continued until the final character D is impressed.
- the printing control circuit 36 repeatedly generates the signals II, III and IV until an output signal from the holding circuit 43 indicates the state of l causing the printing head to travel rightward stepwise, namely, by one order each time.
- the printing section 12 Upon completion of printing, the printing section 12 is not supplied with any other fresh input data.
- the printing head reaches the lower order tabset position 30, a printing end signal S14 is issued to stop the printing head, and the flip-flop circuit 35 of the discriminator 16 is reset, thus providing a condition ready for printing in the third column C3.
- the foregoining embodiment relates to the case where the position in which the foremost order of an input data was to be printed was defined by storing the tabset control register 15 with additional bits corresponding to the number of orders of the input data at a higher order point than, namely, on the left side of the bit already stored therein.
- the abovementioned operation may be replaced simply by shifting the bit stored in the tabset control register 15 to a higher order position.
