Definitions

  • the first object of the present invention is to provide a means by which the required letters are separately printed and yet at a time by the use of the same type belt, so as to enable copies of receipt or data on statistics and so on to be easily obtained.
  • Another object is to simplify the discriminating circuit, for instance the memory device by means of an electronic storage, which becomes much complicated and very expensive with the increase of the printing types.
  • the present invention relates to the high speed printer characterized by that in a high speed printer in which the printing types are secured in line to the running endless belt made of a thin steel plate or the like and the required letters are printed with the rotation of the endless belt by selecting the types corresponding to the letters to be printed from said types, two or more printing sections are disposed against said group of types secured to the endless belt so as to print the required parts separately from the contents which are to be printed, together with printing all of the contents, thereby.
  • FIG. 1 illustrates the brief outline of the printer according to the present invention
  • FIG. 2(A) shows the card in which an example of the contents to be transmitted is written
  • FIG. 2(B) shows the contents, corresponding to the contents shown in FIG. 1, FIG.
  • FIG. 2(A), which are received and printed by the printer shown in FIG. 200) shows an example of partial contents which are received and printed separately from the whole contents shown in FIG. 2(A) by the said printer
  • FIG. 3 is a diagram showing the arrangement between three printing papers and the endless belt to which are secured the printing types in another embodiment of the printer according to the present invention where the printing is effected at three sections
  • FIG. 4 is an oblique View of the endless belt on which the synchronizing holes are arranged at different positions for different groups of types respectively for the purpose of simplifying the discriminating circuit.
  • the printing types 2 are fixed to the endless belt made of a thin steel plate or the like in such a way that they are lined up at equal interval one another parallel to the rim of the belt.
  • the endless belt 1 is engaged with a pair of rotation drums 3 and 3 which are rotated by the motor 4.
  • the interval between the rotation drums 3 and 3 are determined suitably according to the width of the printing paper 5 on which the whole contents transmitted are to be printed and that of the printing paper 5 on which a required part is to be printed sepmately from the whole contents transmitted.
  • the two groups of printing hammers 6 and 6 Facing to the endless belt, the two groups of printing hammers 6 and 6 are disposed.
  • the hammers in each group are arranged by suitable number, i.e. the number of letters for one line to be printed on the respective papers (in the figure is shown only one hammer in each group).
  • These groups of hammers are respectively operated by the two groups of electromagnets '7 and 7 (only one in each group is shown in the figure) and the operated hammers strike the surface of the respective type over an ink ribbon (is not shown in the figure) and the printing paper, and thus the required letters are printed on the paper.
  • the small holes 9 and 9 for synchronization in circumference, each position of which corresponds respectively to the position of each type 2 secured to the endless belt 1.
  • the discriminating circuit 12 is connected in parallel to a part of the other circuit 12 In the figure is shown the case in which the last four terminals of the circuit 12 are respectively connected in parallel to each terminal of the circuit 12 but it goes without saying that each terminal of the circuit 12 is connected in parallel to the terminals of the part of the circuit 12 required to conduct the separate printing.
  • the input codes from the transmitter are received at the terminals 15 and 15 of the discriminating circuits 12 and 12 through the brush 14 from the terminal 13.
  • Each discriminating circuit memorizes the respective input codes, and the outputs of these circuits together with the above-mentioned synchronizing pulses are respectively sent to the electro-m-agnets 7 and 7 through the terminals 16 and 16 then the relative positioning for printing of the hammers 6 6 and the types 2 secured to the endless belt 1 is indicated thereby, and on the print-ing letters 5 and 5 the respective letters for one line are printed by the hammers operated as mentioned above. For instance, if the whole papers as shown in FIG. 2(A) enter as electrical signal into the input terminal 13 of the printer illustrated in FIG.
  • the memory circuit 12 goes on memorizing in sequence the electrical signals corresponding to A, B, C, 1, 2, 3, 4; A, B, C, 1', 2', 3, 4; through each terminal 15 and by the output of this circuit and the synchronizing pulses, the above noted whole letters are printed on the paper 5 as shown in FIG. 2(B).
  • the memory circuit 12 goes on memorizing in order the electrical signals corresponding to 1, 2, 3, 4; 1', 2, 3, 4; through each terminal 15 and by the output of this circuit and the synchronizing pulses, the last letters 1, 2, 3, 4; only are printed on the paper 5 separately from the whole letters as shown in FIG. 2(C).
  • the small holes for synchronizing pulses are arranged on the disks as mentioned above, but it is more favourable to arrange them directly on the endless belt as stated in the specification of the patent application noted in the beginning of the present specification, since the latter removes errors in synchronization.
  • the discriminating circuit for instance the memory device becomes much complicated and expensive as the number of types increases.
  • FIG. 4 shows the endless belt on which the synchronizing holes are arranged so as to remove such complexity with the increase of the number of types thereby.
  • the types 2 2 2 are secured to the endless belt 1 in parallel with its rim after being divided into the group of a, b, c, for instance that of numeral figures, capital letters, small letters of the alphabet and so on, and the synchronizing holes 9 9 9 corresponding to the types 2 2 2 in each group are arranged at different positions each other.
  • These synchronizing holes may be arranged on diiferent circumferences on the disks which is shown in FIG. 1 instead of being arranged directly on the endless belt. In case of printing by one of the groups of types, only the synchronizing pulses for printing by it may be picked.
  • an endless belt carrying an aligned sequence of printing types
  • motor drive means for driving said belt in a path to bring selected types sequentially into proper printing positions with respect to impression paper, said impression paper being fed in a path normal to the path of movement of said belt, at least two separate groups of impression striking elements for cooperation with individual selected types whereby to impress their characters at separate stations relative to the impression paper
  • means controlled by said motor drive means for producing pulses synchronized with the successive positions of said endless belt, individual memory storage devices each having plural output circuits connected to the individual impression striking elements of said separate groups thereof to operate the same in ordered sequence, means connecting said pulse producing means to said memory storage devices to synchronize their outputs with the position of said endless belt, each of said memory storage devices having a plurality of input control and selecting circuits; means for connecting a source of selecting pulses to all of the input circuits of one of said devices, and means for connecting input circuits of at least one other of said devices to selected ones of the input circuits of said one of said devices; whereby a
  • pulse producing means comprises separate pulse producers individually controlled in relation to the location of said types relative to the positions of said stations.
  • each of said separate pulse producers comprises an individual flux-interrupting formation in fixed relationship to the position of an individual one of said types.
