Abstract
Abstract A parallel printing apparatus for data recorded in a store comprises a set of type wheels sequentially set up by a setting wheel, which is transversely moved step by step and is variably rotatable according to the code recorded for each type wheel. The setting wheel is rotated through a clutch which is held engaged under the control of a step counting device sensing a toothed wheel rotated synchronously with the setting wheel. The apparatus is adapted to print on a bank book both parallel and perpendicular to the seam of the book. The book is carried by a carriage, the line spacing of which is effected under the control of a program device.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
249 words
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: a clutch including a continuously power operated driving part, a driven toothed wheel connected to said shaft for concomitant rotation therewith, said toothed driven wheel having a pitch corresponding to the pitch of the type of said type carriers, and connecting means operable under the control of said store for causing said driving part to rotate said driven toothed wheel step by step each time a datum of said recorded coded data in said store is to be printed, a pulse generator for generating a pulse for each step effected by the driven toothed wheel, and means controlled by said store and said pulse generator for generating a disabling signal after said toothed wheel has been rotated a number of steps corresponding to said recorded datum, said connecting means being disabled by said disabling signal.

Dependent Claim
249 words
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: a clutch including a continuously power operated driving part, a driven toothed wheel connected to said shaft for concomitant rotation therewith, said toothed driven wheel having a pitch corresponding to the pitch of the type of said type carriers, and connecting means operable under the control of said store for causing said driving part to rotate said driven toothed wheel step by step each time a datum of said recorded coded data in said store is to be printed, a pulse generator for generating a pulse for each step effected by the driven toothed wheel, and means controlled by said store and said pulse generator for generating a disabling signal after said toothed wheel has been rotated a number of steps corresponding to said recorded datum, said connecting means being disabled by said disabling signal.
Claim 3
Dependent Claim
51 words
An apparatus according to claim 1, wherein 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.
Claim 4
Dependent Claim
36 words
An apparatus according to claim 1, 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.
Claim 5
Dependent Claim
62 words
An apparatus according to claim 3, wherein 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.
Claim 6
Dependent Claim
38 words
An apparatus according to claim 4, comprising a control element operable by each of said escapement teeth when in engagement with said spacing member, and means for engaging said clutch following upon the actuation of said control element.
Claim 7
Dependent Claim
34 words
An apparatus according to claim 4, 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.
Claim 8
Dependent Claim
56 words
An apparatus according to claim 3 wherein the setting wheel is toothed, and comprising a series of intermediate toothed wheels connected to said type carriers by said setting wheel sequentially engaged, the teeth of said setting wheel being tapered parallel to the axis of said setting wheel to assist the engagement thereof with said intermediate wheels.
Claim 9
Dependent Claim
32 words
An apparatus according to claim 7, wherein 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.
Claim 10
Dependent Claim
56 words
An apparatus according to claim 8, 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.
