Abstract
Abstract This invention relates to a selective printing mechanism. The printing apparatus includes several carrousels which are themselves mounted on a principal rotating plate. Each carrousel supports, in addition to rotating cylinders having printing characters, charactercarrying elements fixed with respect to the plate of the respective carrousel. The principal rotating plate carries also rotating printing cylinders and character-supporting elements fixed with respect to its plate. The rotating unit thus constituted can be disposed horizontally behind the paper and the whole of this unit and of a percussion element is displaceable horizontally at each stroke, in order to type a line of characters. This apparatus has particularly efficient application to the construction of a typewriter for printing in the Chinese or Japanese languages.

Claim 1
Independent Claim
273 words
A typing machine for selectively typing on a sheet a large number of characters, said machine comprising: I. 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: A. a first plate rotatable about a first longitudinal axis, a plurality of printing cylinders mounted on second axes rotatably mounted parallel to said first axis about the periphery of said first plate, said printing cylinders having about the periphery thereof rows of characters extending parallel to said first axis; B. 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; C. 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; D. at least one row of characters, extending parallel to said first axis, fixedly mounted to said second plate about the periPhery thereof between adjacent of said auxiliary printing cylinders; and E. at least one row of characters, extending parallel to said first axis, fixedly mounted to said first plate about the periphery thereof between adjacent of said printing cylinders and said at least one carrousel; and II. 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.
Claim 2
Dependent Claim
273 words
A typing machine for selectively typing on a sheet a large number of characters, said machine comprising: I. 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: A. a first plate rotatable about a first longitudinal axis, a plurality of printing cylinders mounted on second axes rotatably mounted parallel to said first axis about the periphery of said first plate, said printing cylinders having about the periphery thereof rows of characters extending parallel to said first axis; B. 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; C. 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; D. at least one row of characters, extending parallel to said first axis, fixedly mounted to said second plate about the periPhery thereof between adjacent of said auxiliary printing cylinders; and E. at least one row of characters, extending parallel to said first axis, fixedly mounted to said first plate about the periphery thereof between adjacent of said printing cylinders and said at least one carrousel; and II. 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.
Claim 3
Dependent Claim
40 words
A machine as claimed in claim 1, further comprising means to move one of said printing assembly and said hammer means relative to the other of said printing assembly and hammer means in a direction parallel to said first axis.
Claim 4
Dependent Claim
87 words
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.
Claim 5
Dependent Claim
123 words
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.
Claim 6
Dependent Claim
16 words
A machine as claimed in claim 2, wherein said means for moving moves said hammer means.
Claim 7
Dependent Claim
27 words
A machine as claimed in claim 1, wherein each of said rows of characters has an equal number of characters, said number being from 11 to 14.
Claim 8
Dependent Claim
27 words
A machine as claimed in claim 1, wherein said plurality of printing cylinders comprises three printing cylinders each having about the periphery thereof 15 rows of characters.
Claim 9
Dependent Claim
51 words
A machine as claimed in claim 7, wherein said at least one carrousel comprises three carrousels, and said plurality of auxiliary printing cylinders comprises six auxiliary printing cylinders about the periphery of each of said carrousels, each of said auxiliary printing cylinders having about the periphery thereof eight rows of characters.
Claim 10
Dependent Claim
31 words
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.
