Definitions

  • an object of this invention is to effectively improve these drawbacks.
  • the invention provides a printing apparatus which is capable of automatically printing a character bearing a special mark simply by inserting special codes immediately before and after a character or a set of characters to be marked.
  • the present invention provides a new and improved printing apparatus comprising an input device, printing device, printing position shifting device, mark printing device and stopping device, as described below.
  • the input device provides print data by inserting the start and end codes of a special mark immediately before and after a character or a set of characters to be marked.
  • the printing device performs the printing operation according to the print data from the input device.
  • the printing position shifting device is driven step by step in accordance with the printing operation of the printing device.
  • the mark printing device adds a special mark to the printed character by detecting the start code of the mark from the input device such that the mark is printed at that spot where the character is previously impressed in succession to the start code in the step by step printing.
  • the stopping device stops the printing operation of the mark by detecting its end code.
  • FIGURE is a block diagram of a printing apparatus embodying this invention.
  • An input device 1 1 has a character input device 12 for providing character data containing an underline and an underline key 13 for giving a PRINT UNDERLINE instruction.
  • the character input device 12 provides, for example, eight-bit binary-coded character data.
  • a well known key input device, data processor, tape reader, etc. are available for this purpose.
  • a coded expression AB-CD-EF is used as the print data from the input device 1 1.
  • the binary-coded data corresponding to the character A obtained from the character input device 12 is fed to the decoder 15 of a printing device 14.
  • the binary-coded signal is decoded in the decoder 15 to form a signal corresponding to the character A.
  • This signal is transmitted to a printer 16 on a line L1 to print the character A on the recording sheet.
  • the signal is further delivered from the line L1 to a delay circuit 18 through an OR gate 17 and, after a predetermined delay, to the one input terminals of AND gates 19 and 20. Since the output of a binary counter 21 in this case represents 0, there is no output from the AND gate 19.
  • the AND gate 20 is enabled by the output from an inverter 22 and supplies its output to a printing position shifting device 24 through an OR gate 23.
  • the printing position of the printer 16 is shifted by one character a predetermined time after the character A has been printed. Similarly, the succeeding character B is then printed.
  • the output signal representing the underline start code is delivered from the key 13 to a binary counter 21 to convert the output of the counter 21 into l
  • the output of the inverter 22 becomes 0, thereby disabling the AND gate 20 and enabling the AND gate 19.
  • the underline-printing data is composed, for example, of an eight-bit binary code (01000001) such that the second bit from the most significant one and the least significant bit are supplied to the input terminal of the decoder 15 via OR gates 25 and 26. Whenever there is an output from the AND gate 19, the underline-printing data is fed to the decoder 15.
  • the binary-coded data corresponding to the character C is produced from the character input device 12, and decoded in the decocer 15, thus sending the PRINT instruction of the character C from a line L(nl) to the printer 16 to print the character C.
  • This signal giving the PRINT instruction to print the character C is delivered to the AND gate 20 through the OR gate 17 and delay circuit 18.
  • the AND gate 20 is disabled by the output from the binary counter 21. Therefore, the printing position shifting device 24 will not be driven when the character C has been completely printed. The printing position will thus be stationary, retaining the position in which the character is just printed.
  • the AND gate 19 will be enabled by the outputs from the delay circuit 18 and binary counter 21.
  • the binary-coded underline data will be fed to the decoder 15 through OR gates 25 and 26 to be decoded therein.
  • the PRINT-UNDERLINE instruction will thus be sent from a line Ln to the printer 16 so that the previously printed underlineless character C will be underlined in the correct position.
  • the signal giving a PRINT-UNDERLINE instruction generated in the line Ln will further be delivered to a delay circuit 27.
  • the output from the delay circuit 27 will appear a given time after the character C has been underlined and will be fed to the printing position shifting device 24 through the OR gate 23.
  • the PRINT instruction of the character D will be given from the de coder to the printer 16 on a line L3 to print the character D. Since the AND gate 20 in this case is disabled, the printing position will not be shifted even when the character D is printed.
  • the underline data is given to the decoder 15 by the output of the AND gate 19, the PRlNT-UNDERLINE instruction will be given to the printer 16 on the line Ln the character D to underline the character D so as to cause the two adjacent underlines of characters C and D to be unbroken. Thereafter, the printing position will be shifted by one character as in the preceding character C.
  • the printing position is unfailingly shifted after printing by a SHIFT- instruction signal to make printing preparations.
  • the PRINT-UNDERLINE instruction signal may also be used instead of the SHIFT- instru'ction signal, depending on the underline signal.
  • the binary counter 21 may also be replaced, for example, by using flip-flops expressed in terms of set and reset when the start code differs from the end code.
  • the present invention provides a new and improved printing apparatus capable of effectively printing a special mark step by step without backspacing. This is very effective not only in employing ordinary manual character printers but also in automatically recording data from various data processing devices.
