  • Each apparatus 81, S2 is controlled by means of a corresponding electronic control unit G1, G2, respectively, from a central unit C.
  • This unit is connected to a central computer by means of a transmission unit T and a telephone or telegraph line L, as a result of which the apparatus S1 constitutes a part of a data transmitting terminal.
  • the central unit includes a store M adapted to store the data to be written on the apparatus S1.
  • the printing is effected through the medium of a series of type-carrying elements which are set serially in accordance with the data recorded in the store M and are then operated to write in parallel a whole line of data at a time.
  • the transmission unit T provides in known manner for the control of the programming language, the keeping of a check on errors, the serialization of the data to be transmitted and the parallelization of the data received.
  • Each slider 14 is moreover provided with a projection 23 normally bearing against a universal bar 24 by the action of a spring 25.
  • said spring 25 is adapted to cause the wheel 11 to strike against a resilient pad 26.
  • the universal bar 24 is carried by two arms 27 and 28 fixed on a shaft 29 which can turn in the fixed frame of the machine.
  • the arm 28 normally bears against a cam 33 fixed on a main shaft 34 controlling the writmg.

  • the crank is fixed on the shaft 34 and is provided with a pin 49 engaged in a slot 51 in the slider 46.
  • Said slider 46 is moreover connected by a pin and slot to the lever 53 which can turn on the shaft 34 and is connected to the crank 48 by a spring 54.
  • a projection 55 of the lever 53 is normally biased by the spring 54 to bear against a lug 56 of a lever 57 fulcrumed on a fixed pin 58.
  • the lever 57 is normally held so that it bears against a fixed stop 59 by means of a spring 61 and is connected by a pin and slot to an armature 62 of a printing electromagnet 63.
  • Each type wheel 11 (FIG. 1) is normally in engagement with a corresponding toothed wheel 76.
  • the wheels 76 are rotatable on a shaft 77, which is rotatable in turn in the fixed frame of the machine.
  • Each wheel 76 is provided in the center with a depression 78 into which a zerozing tooth 79 projects.
  • a corresponding tooth 81 carried by the shaft 77 can cooperate with each tooth 79.
  • a lever 84 On the main shaft 34 (FIG. 3), there is fixed another cam 82 against which a lever 84 normally bears by the action of a spring 83.
  • the lever 84 is fulcrumed on a fixed pin 86 and is connected by a pin and slot to an arm 87 fixed on a spindle 88 which can turn in the fixed frame of the machine.
  • a universal bar 89 is carried by the arm 87 and by a second arm 91 also fixed on the spindle 88 and is adapted to cooperate with a series of positioning members 92. These positioning members are fulcrumed on a spindle 93 carried by two right-angled or bracket portions 95 (FIGS. 1 and 2) of the fixed frame of the machine.
  • the tooth 96 of the positioning member 92 is brought into the path of the projection 97 of the slider 14, as a result of which the character cannot be written as long as the wheel 76 is in the inoperative position.
  • This character can, however, be written after the wheel 11 has been rotated for a complete revolution.
  • the diameter of the wheel 76 is greater than that of the wheel 11, so that the wheel 11 can be rotated anticlockwise for a complete revolution to select any character without the tooth 79 of the corresponding wheel 76 reaching the tooth 81 of the shaft 77.
  • the printing apparatus is provided with a serial setting device for the type wheels (FIG. 1) which includes a toothed setting wheel 108 having a pitch equal to that of the wheels 76 and 11.
  • the wheel 108 (FIG. 2) is provided with teeth which extend laterally with tapered portions 109 in the form of truncated cones for assisting the transverse engagement of the wheel 108 with the different wheels 76.
  • the wheel 108 is integral with a pinion 110 which is in mesh with a pinion 111.
  • the last-mentioned pinion is provided with a hub 115 slidable axially on a splined shaft 112, but fast angularly therewith.
  • the wheel 108 and the pinions 110 and 111 are mounted on a carriage constituted by a bail 113 having two arms 114 and 116 (FIG. 1) which can turn on the hub 115 but are fast axially therewith.
  • the arm 114 of the bail 113 is provided with a pin 117 on which the wheel 108 and the pinion 110 can turn.
  • the arm 116 (FIG. 4) of the bail 113 is provided with a slot 121 in which there engages a transverse bar 122. This bar is carried by two arms 123 and 124 fixed on a spindle 125 which can turn in the fixed frame of the machine.
  • the am 123 is nonnally held so that it bears through the action of a spring 126 against a cam 127 fixed on the main shaft 34.
  • the escapement wheel 129 acting through the reel 132 and the cable 133, causes the bail 340 to move to the right step by step together with the slider 344 and the wheel 108.
  • the pinion 355 is then rotated anticlockwise through the medium of the sleeve 128, causing the sector 353 to turn clockwise, as a result of which the roller 352 approaches the bottom of the cam 351.
  • the plate 225 is provided with another window 242 (FIG. 2) disposed between the two windows 220 and extending to the rear for a length equal to the maximum advance that the book 222 (FIG. 1) can have.
  • This plate is provided with a vertically bent portion246 (FIG. 1) which is bent to form another longitudinal lug 247 fixed by means of two adjusting screws 248 to a carriage 249.
  • a microswitch 245 adapted to be closed by the book 222 to indicate the presence thereof.
  • the carriage 249 includes two apertured bent portions 250 and 251 slidable longitudinally on a bar 252 of rectangular section.
  • the bar 252 is fixed to two angle irons 253 secured to the plate 225.
  • the gear 264 is of plastics material and is integral with a positioning wheel 266 provided with a notch for each line to be written in the book.
  • the wheel 266 therefore comprises a first portion 267 devoid of notches and corresponding to the upper margin of the book 222, that is to say to the space above the first line of writing, and a second portion 263 devoid of notches and corresponding to that part of the book 222 which is adjacent the fold 223 (FIG. 1), which is not used for the record.
  • the wheel 266 (FIG. 7) moreover comprises a projection 269 which defines the rest position of the carriage 249 (FIG. 1).
  • the two cranks 241 engage the crosspieces of the respective bails 238, which are then turned in such manner as to move the pressure rollers 236 away from the rollers 229.
  • the pin 311 (FIG. 7) of the crank 312 in turn, carries the positioning member 270 along anticlockwise, releasing the wheel 266.
  • the spring 260 (FIG. 1) then pulls the rack 256 forward together with the carriage 249 and the lugs 243, which push the book 222 forward.
  • a fourth signal CF generated on the reception of the end-ofmessage character, is sent via an AND-gate 322 and an OR- gate 325 to a circuit 323 commanding the ejection of the book 222 (FIG. 1).
  • the circuit 323 (FIG. 10) comprises a flip-flop and is connected to the ejection electromagnet 302.
  • the decoder 315 does not recognize any signal, as a result of which the four circuits 316, 318, 321 and 323 are not affected.
  • the register 324 is filled with the inverse of the bits C1-C4, which represents the complement of the value of said bits to 16. If the code received is that of zero, the inverse of which is 1111, it is recognized by the decoder 326, which therefore emits a signal. In the meantime, the wheel 186 has begun to turn to select the corresponding character.
  • the signal S emitted by the gate 327 also reaches the circuit 318 commanding the advance via the OR-gate 317 and said circuit then energizes the advance electromagnet 160.
  • This magnet causes the tooth 143 to be disengaged from the wheel 129 (FIG. 4) and engages the tooth 144 therewith, as a result of which the microswitch 156 opens temporarily.
  • the tooth 144 recloses the microswitch 156 (FIG. 10), generating a signal FA in known manner.
  • This signal resets the register 324 via the gate 337 and, on the other hand, changes over the flip-flop 333, which now generates a signal DC for the following character request.
  • the signal DC temporarily inhibits the staticizer 332. Moreover, this signal causes the OR-gate 331 to emit another character request signal RC, as a result of which a fresh reception cycle begins. If the code received is again a printable character code, the first signal emitted by the generator 219 through the gate 336 changes over the flip-flop 333.
  • the gate 327 causes the circuit 316 to change over, the circuit 318 is also changed over and now causes the advance electromagnet 160 to be deenergized, thus causing the tooth 143 to be reengaged with the wheel 129 (FIG. 4) and causing the setting wheel 108 to perform another transverse step. All the other operations following the advance are effected as in the preceding case.
  • this decoder emits in each case a signal CN which inhibits the circuit 316 commanding the selection. More particularly, if the code received is that of the space character, for example for spacing one group of digits from another during printing, or for preventing the printing of the nomiignificant zeros of an amount, this code is recognized by the decoder 315, which emits a signal CS in addition to the signal CN.
  • the signal CS changes over the flip-flop 333, while via the gate 317 it changes over the circuit 318, immediately commanding the transverse advance of the setting wheel 108 (FIG. 4) as in the case of the selection of a printable character.
  • the closing of the microswitch 156 changes over the flip-flop 333, producing a request for another character to the central unit C, while it resets the register 324 via the gate 337.
  • the circuit 321 then energizes the printing commanding electromagnet 63 for a time of about 200 ms., thus commanding a cycle of the main shaft 34 (FIG. 5), as a result of which the data that have been set are written in the book 222. Since the energization of the electromagnet 63 has a duration less than the duration of the cycle of the main shaft 34, the shaft is stopped in any case at the end of the cycle. Moreover, the circuit 321 (FIG. 10) changes over the flip-flop 333 via the gate 336, as a result of which any further request for characters is blocked.
  • the circuit 321 inhibits the circuit 318, so that the electromagnet is in any case deenergized and causes the tooth 143 to be reengaged with the wheel 129 (FIG. 4) irrespective of the fact that the last tooth in engagement therewith before the printing operation might have been the tooth 143 or the tooth 144.
  • a parallel printing apparatus for recorded data including a store for recording said data in coded form, a series of similar type carriers each one carrying a plurality of types, said type carriers being mounted for individual movement from a rest position to a differential position to select a type to be printed, a setting wheel mounted on a shaft to be angularly bodily rotated therewith, means for axially shifting said setting wheel on said shaft to cause said setting wheel to be coupled with said type carriers in succession for individually setting each of said type carriers, and means for producing the printing action in parallel after such setting wherein the improvement comprises:
  • said generator comprises an oscillator and a ferromagnetic core adapted to cooperate directly with the driven wheel to damp the oscillator on the passage of each tooth of said driven wheel to generate a pulse irrespective of the speed of passage of said tooth.
  • An apparatus comprising an escapement device for controlling said setting wheel to be axially shifted step by step, and means effective in response to said disabling signal for actuating said escapement device.
  • the escapement device comprises a toothed spacing member, a pair of escapement dogs alternately engaging and disengaging said spacing member, an oscillating plate mounting said escapement dogs, an electromagnet for oscillating said plate, and circuit means for energizing said electromagnet consequent upon alternate disengagements of said clutch and for deenergizing it consequent upon intervening disengagements.
  • An apparatus comprising means operable during the printing to control the electromagnet in such manner as to engage a predetermined escapement tooth of the said pair with said spacing member.
  • each of said type carriers comprises a toothed-type wheel meshing with a corresponding intermediate wheel and bearing the type on outer surface of its teeth.
  • An apparatus comprising a series of supports associated with said type wheels each of said supports rotatably mounting a corresponding one of said type wheels, and a universal bar controlling the supports to cause said type wheels to print in parallel the set data under the control of a cyclic actuating mechanism.
  • An apparatus comprising a common stationary shaft rotatably mounting said intermediate wheels, said type wheels being disengaged from said intermediate wheels during the printing operation, locking means being provided for locking said type wheel and said intermediate wheels during the printing.
  • said locking means comprises a series of positioning members normally engaging said intermediate wheels, one of the spaces between the teeth of said intermediate wheels having a greater depth than the others for defining the inoperative position of said intermediate wheels, and an element secured to each one of said positioning members and adapted to prevent the striking movement of the support of the corresponding type wheel, when the corresponding positioning member engages the space of greater depth.
  • An apparatus comprising a series of cam elements secured to said common shaft, means for rotating said common shaft on the reengagement of said type wheels with said intermediate wheels to bring said intermediate wheels back into their inoperative position together with the type wheels, and means for causing said universal bar to disengage said positioning members from said intermediate wheels during a first part of the return of the intermediate wheels to rest and to reengage them with said intermediate wheels during a final part of the return to rest.
  • An apparatus including a pawl comprised in said return means, operating means to actuate said pawl at constant speed during the printing operation for moving the setting wheel back, and a cam element for rendering said pawl inoperative after the setting wheel has been brought back to its rest position.
  • An apparatus comprising a pivot member rotatably mounting said setting member and carried by a sliding support which is slidable transversely, and resilient means for holding said sliding support in a position as to engage said setting wheel with said intermediate wheels.
  • An apparatus comprising a cam cyclically operated to bring the setting wheel transversely towards the rest position during the writing operation, said cam arranging the setting wheel temporarily at a transverse position where it is in engagement with said intermediate wheels during a period in which they are brought back angularly to rest.
  • An apparatus engaging the document and rotatable to print on a bank book or other flat document, comprising at least one pair of rollers adapted to cause the document to advance by friction, and a carriage movably mounted parallel to the advancing movement of the document, said carriage comprising a part engageable by the document for controlling the advance and being arranged to be actuated by a line spacing mechanism connected thereto and concomitantly operated with said means for producing the printing action.
