Abstract
Abstract The disclosure relates to a data indicating device for printing machines wherein a plurality of rotatable type wheels adjacently aligned, and respectively inscribed with printing numerals on the peripheries thereof are each furnished with a gear at one side thereof, and the same number of rack bars are arranged each to engage the gear of the type wheel, and manual operating end portions of the rack bars project out of the machine housing in spaced relation. To these operating portions are connected flexible data indicating bands bearing on one face thereof numerals corresponding to the printing numerals on the peripheries of the type wheels, and these bands are guided on a concave curved inner surface to windows formed in the machine housing, thereby to indicate at the windows the selected printing numerals corresponding to those on the type wheels which are rotated by manipulation of the operating and portions of the rack bars.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
247 words
Data indicating device for printing machines comprising housing means; at least one type means having angularly spaced types and mounted on said housing means for turning movement; operating means including manual means and being mounted on said housing means for movement, said operating means being connected with said type means for turning the same stepwise between a plurality of angular positions in which different types are in a printing position; a control panel on said housing means having a wall portion with a curved concave inner guide face and at least one window opening on said inner guide face; holding means supported on said panel located inward of said curved concave inner guide face and having at least one gUide face confronting said curved concave inner guide face and forming at least one gap with the same; and at least one flexible data indicating band having a portion with a row of indicia spaced corresponding to said types, said band having one end secured to said manual means, and a free end threaded through said gap, said band having a thickness corresponding to the width of said gap so that the outer face of said portion of said band is slidingly guided on said curved concave inner guide face, whereby due to simultaneous turning of said type means and movement of said band by said manual means that index is always located directly under said window which corresponds to that type which is in said printing position.
Claim 2
Dependent Claim
247 words
Data indicating device for printing machines comprising housing means; at least one type means having angularly spaced types and mounted on said housing means for turning movement; operating means including manual means and being mounted on said housing means for movement, said operating means being connected with said type means for turning the same stepwise between a plurality of angular positions in which different types are in a printing position; a control panel on said housing means having a wall portion with a curved concave inner guide face and at least one window opening on said inner guide face; holding means supported on said panel located inward of said curved concave inner guide face and having at least one gUide face confronting said curved concave inner guide face and forming at least one gap with the same; and at least one flexible data indicating band having a portion with a row of indicia spaced corresponding to said types, said band having one end secured to said manual means, and a free end threaded through said gap, said band having a thickness corresponding to the width of said gap so that the outer face of said portion of said band is slidingly guided on said curved concave inner guide face, whereby due to simultaneous turning of said type means and movement of said band by said manual means that index is always located directly under said window which corresponds to that type which is in said printing position.
Claim 3
Dependent Claim
79 words
Data indicating device as claimed in claim 1 including a guide block secured to said wall portion and having a curved concave inner guide face forming a continuation of said curved concave inner guide face of said wall portion and wherein said curved concave inner guide face of said wall portion and said curved concave inner guide face of said block together extend over substantially 180* for guiding the free end of said band back toward said manual means.
Claim 4
Dependent Claim
48 words
Data indicating device as claimed in claim 1 wherein said holding means include a plurality of angularly spaced holding members forming a plurality of angularly spaced gaps along said curved concave inner guide face for guiding said band along angularly spaced portions of said curved concave guide face.
Claim 5
Dependent Claim
28 words
Data indicating device as claimed in claim 3 wherein one of said holding members includes a holding bar mounted in confronting recesses of said panel and said block.
Claim 6
Dependent Claim
22 words
Data indicating device as claimed in claim 1, wherein said wall portion is slanted for observation of said indicia through said window.
Claim 7
Dependent Claim
38 words
Data indicating device as claimed in claim 1, wherein said operating means include a gear secured to said type wheel, and a rack bar meshing with said gear and having a manually operated part constituting said manual means.
Claim 8
Dependent Claim
51 words
Data indicating device as claimed in claim 6, wherein said part includes horizontal and vertical portions, said manually operated vertical portion having a manually operated end portion and being aligned with said window; and wherein said one end of said band is secured to said end portion of said vertical portion.
Claim 9
Dependent Claim
56 words
Data indicating device as claimed in claim 1, comprising a spring biased roller mounted in said panel and to which said free end of said band is secured so that said band is rolled up on said roller by a spring force when said band is pushed by said manual means along said curved guide face.
