No.: 368,588
  • FIG. 1 shows the schematic arrangement of a carrou-
  • the present invention relates to mechanisms for sesel printing assembly according to the invention
  • the invention thus has for its object to resolve such a problem, permitting the provision of a mechanism capable of printing selectively a large number of characters, possessing acceptable inertia and execution time, and requiring a relatively small space.
  • the present invention is based on the utilization of at least one carrousel having wheels or cylinders carrying printing characters on their periphery and turning about their individual axes.
  • At least one carrousel is carried on a plate turning about a principal axis or rotation, the wheels being capable ofturning about their individual axes perpendicular to the plate, independently of the rotation of the latter.
  • a unique movable element external to the carrousel and capable of controlled percussion disposed relative to the printing location at the periphery of the carrousel. to which any character can be brought, the whole assembly being such that the printing can be effected upon a sheet placed between the movable element and the printing location.
  • a carrousel of printing wheels or cylinders which include, on the one hand, several wheels supporting printing characters carried by a plate turning about a principal axis of rotation, such wheels being capable of turning about their individual axes perpendicular to the plate and independently of the rotation proper of the latter, and on the other hand, elements rigidly fixed to the plate at its exterior periphery. supporting printing characters situated at the same distance from the principal axis of the plate as are the characters ofthe wheels when they are found in the peripheral printing position, these fixed elements being located at intervals between the said wheels.
  • Flg. 2 is an enlargement, executed in detail, of a part of the printing assembly
  • FIG. 3 is an axial section of the assembly, to a scale smaller than that of Flg. 2;
  • FIG. 4 shows the general schematic arrangement of a printing assembly with a large number of characters
  • FIG. 5 shows a very small part of the key board" constituting a part of the assembly of FIG. 4 by way of illustration.
  • a carrousel C such as one of the three shown in FIG. I.
  • the present invention is not limited to the embodiment hereinafter described, that is, the printing of Sino-Japanese ideograms it will be assumed initially, in order to explain the invention, that there exists only one of these carrousels (C,).
  • the carrousel in the present case carried by a plate 1 includes six cylinders (or wheels) 2 to 7, each supporting a plurality of rows of characters (8 in number) about their periphery. These cylinders are perpendicular to the plate 1 and capable of turning about their pivots or axes 11,11, also perpendicular to the plate.
  • the plate turns about an axis 12 parallel to axes 11, 11', the movements of the axis 12 and of axes 11,11 being independent.
  • a movable percussion or hammer element 8 is activated to apply the paper 10 against the selected character (arrow F, FIG. 1) which has been brought to the printing location, in relation to which the movable element is located.
  • a key board or table of characters 13 is utilized (of which the enlarged view can been seen in FIG. 5, with the illustration of a few characters).
  • Each character of the key board is in fact a metallic plaque isolated from the others and including a printed circuit, each one associated with means (not shown) which make it a small generator of coded impulses of a limited number and of characteristic sequential arrangement.
  • the chosen character With the aid of a stylus 14, the chosen character is brought to a predetermined potential. This manoeuvre causes the emission of a series of coded impulses, characteristic of the chosen character.
  • the series of impulses is sent to the logic unit 15 constituting a memory and control organ.
  • This organ inproximately at the same time, if that is possible.
  • the unit 15 controls the rotations of the axes l2 and 11,11 for example by respective step-wise ratchet systems 16, 17, causing movement of the corresponding gearing.
  • the rotations of the plate or cage 1,1 and of the cylinders 2 to 7 are controlled.
  • the element 8 is displaced along a vertical rod, for example one that is threaded and meshing with a part similar to a nut carried by the element 8.
  • the rod turns for example under the action of a small motor 18.
  • a comparator 19 is connected by multiple lines to the table 13 on the one hand, and on the other hand to means which establish the position of the different coordinates" of the characters with respect to the printing location.
  • the comparator orders the printing, by way of the logic unit and an electromagnet 9 which serves to urge the element 8 with percussive force against the chosen character, with the sheet 10 sandwiched between.
  • ratchet 16 moves the axis 12 around 180 and thus causes such cylinder of carrousel C. to face the hammer 8.
  • ratchet l7 rotates the selected cylinder of carrousel C about its axis to position the row of characters containing the selected character "A" facing the top end of the hammer 8.
  • Motor 18 moves the hammer 8 upwardly or downwardly to make it face the position of the character A" of the carrousel C,.
  • a signal from a known device such as an incoder (not shown) mounted on the ratchet systems 16 and 17 and motor 18 is received by the comparator 19.
  • the comparator 19 When the signal from the incoder and the signal from the key board 13 selected by the stylus 14 coincide, the resultant signal is fed to the logic unit 15.
  • the unit 15 feeds percussive force to the electro-magnet 9, so the magnet 9 urges the hammer 8 toward the character and the selected character A is printed on the sheet 10.
  • the plate 20 or more exactly the cage formed by the plates 20, 21 turning freely on the axis 22, supports three printing cylinders 23, 24, 25. It also carries three identical auxiliary carrousels C C C the make-up of which has already been described for C and six elements 26 to 31, fixed to the plate, all of these elements supporting characters, and all of the printing characters supported by these elements being capable of being moved to the printing location to effect printing (arrow F).
  • the number k of characters of the fixed elements 26 to 31 on the principal plate 20 is represented as follows:
  • each cylinder e.g. 23
  • the edge of the plate 20 carries gear teeth G meshing with a gear wheel H. This movement thus causes the principal plate to turn about the axis 22, and independently of it.
  • the shaft 22 For the second movement (II), the shaft 22 carries, keyed to itself, a gearing 32 which receives its movement from a toothed wheel 33. At its other extremity, the shaft 22 carries, keyed to itself, a toothed wheel F meshing with three wheels E which directly rotate the cylinders 23, 24, 25. This movement thus brings about the rotation of the said cylinders on their individual axes.
  • a toothed wheel D includes a sleeve received on the shaft 22 without engaging the same. It meshes at 34 with wheels C fixed with respect to each of the plates of the three auxiliary carrousels and it is rotatable because it is fixed with respect to a toothed wheel 35 which is rotated by an exterior wheel 36. This movement thus provides the rotation of the plates of the auxiliary carrousels.
  • an exterior wheel 37 meshes with a central gear 38 turning about the sleeve of the wheel D without engagement therewith; the wheel 38 meshes with the wheels 39 (of which one is shown in FIG. 3).
  • Each wheel 39 is keyed on a shaft 40, independent of the rotation of the auxiliary carrousel plate which carries, fixed with respect to itself, a wheel B which rotates. by way of wheels such as A, the six printing cylinders of the carrousel. This movement thus provides the rotation of the rotating printing cylinders of the auxiliary carrousel.
  • the assembly is well balanced and could be displaced as a unit through horizontal sliding while still being hidden from the view of the operator and at least in part, while the percussion element is in a fixed location. It will have been supposed also here that the paper is displaced in stepwise fashion relative to the printing location by one character for each stroke. It is also possible to suppose that the paper is fixed. In this case, the carrousel assembly will be preferably horizontal and the whole of this assembly and the printing element will move step by step with each stroke, in order to print a horizontal line of characters.
  • a typing machine for selectively typing on a sheet a large number of characters comprising:
  • a printing assembly containing thereon a plurality of characters and mounted to bring a selected one of said characters to a printing position, said printing assembly comprising:
  • At least one carrousel including a second plate rotatably mounted about a third axis parallel to said first axis about said first plate between adjacent of said printing cylinders;
  • said at least one carrousel having a plurality of auxiliary printing cylinders rotatable about fourth axes, parallel to said first axis, about the periphery of said second plate, each of said auxiliary printing cylinders having about the periphery thereof rows of characters extending parallel to said first axis;
  • hammer means mounted adjacent said printing position for forcing a sheet against a selected one of said characters when said printing assembly has brought said selected character to said printing position.
  • a machine as claimed in claim 2 further comprising first drive means operatively associated with said first plate for selectively rotating said first plate about said first axis; second drive means operatively associated with said printing cylinders for rotating said printing cylinders about said second axes; third drive means operatively associated with said second plate for rotating said at least one carrousel about said third axis; and fourth drive means operatively associated with said auxiliary printing cylinders for rotating said auxiliary printing cylinders about said fourth axes.
  • a machine as claimed in claim 3, further comprising keyboard means containing a representation of each of said characters for emitting impulses representative of each of said characters upon the selection of each of said characters; logic and control means interconnecting said keyboard means.
  • said means for moving and said drive means for receiving impulses from said keyboard means representative of the selection of a character and operating said drive means and said means for moving for bringing said selected character to said printing position opposite said hammer means; and comparator means operative to compare said selected character and the character brought to said printing position and operate said hammer means to force said sheet against said selected character at said printing position.
  • each of said rows of characters has an equal number of characters, said number being from 1 l to 14.
  • a machine as claimed in claim 8, wherein said at least one row of characters fixedly mounted to said first plate comprises four rows between each adjacent printing cylinder and carrousel.
