Abstract

Abstract An imprinting device is disclosed wherein the imprinter roller assembly is loosely connected to the assembly carriage, the imprinter roller being supported at each end thereof by a roller cluster. Each roller cluster is supported by a flexible metal band, the band being fixedly connected at one end of the imprinter and adjustable connected at the other end thereof, each band being confined at the top and bottom thereof by suitable tracks disposed along the imprinter length. Each band passes over and around one of the rollers of its associated roller cluster and then around and under the other roller of its associated cluster. The corresponding rollers of each cluster are connected together by appropriate means. The points where the bands are fixedly connected to one end of the imprinter are disposed immediately above the print bed level, this end of the imprinter corresponding to the start position of the imprinter head. The print bed is provided with a recess, the depth of which is slightly greater than the card body thickness, this recess receiving the printing plate or card prior to the imprinting operation. A document or invoice is placed over the printing plate and onto the print bed. The document is held in place during the imprinting operation by the bands which are drawn over the invoice as the imprinting operation takes place. Thus, no movement of the document occurs during imprinting. The imprinting head is then returned to its initial position, a second imprinting operation occurring during this return stroke. The document remains securely in place with respect to the position in which it was held during the first imprinting stroke since the bands are withdrawn as the second imprinting operation occurs. With the head returned to its initial position, the document and printing plate can be removed.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 249 words
Printing apparatus comprising: a print bed; a carriage having at least two rollers disposed at opposite sides thereof and cooperating with opposite sides of said printing apparatus for movement of said carriage over said print bed; a roller platen; means loosely connected between said carriage and said roller platen for moving said roller platen whenever said carriage is moved; first and second channels respectively disposed at two sides of said printing apparatus; first and second roller pairs respectively disposed and connected to opposite ends of said roller platen and respectively disposed within said first and second channels, one of said rollers of said first roller pair being connected to one of the rollers of said second roller pair and the other roller of said first roller pair being connected to the other roller of said second roller pair; first and second flexible bands respectively disposed within said first and second channels, each band being coNnected at one end of said printing apparatus at the top of its associated channel and at the other end thereof at the bottom of its associated channel and each band passing from its connection at said one end of the imprinting apparatus over and around one roller of its associated roller pair and then around and under the other roller of its associated roller pair and thence to said connection at the other end of said printing apparatus; and whereby an imprint is created whenever said roller platen is moved across said print bed.
Claim 2
Dependent Claim 249 words
Printing apparatus comprising: a print bed; a carriage having at least two rollers disposed at opposite sides thereof and cooperating with opposite sides of said printing apparatus for movement of said carriage over said print bed; a roller platen; means loosely connected between said carriage and said roller platen for moving said roller platen whenever said carriage is moved; first and second channels respectively disposed at two sides of said printing apparatus; first and second roller pairs respectively disposed and connected to opposite ends of said roller platen and respectively disposed within said first and second channels, one of said rollers of said first roller pair being connected to one of the rollers of said second roller pair and the other roller of said first roller pair being connected to the other roller of said second roller pair; first and second flexible bands respectively disposed within said first and second channels, each band being coNnected at one end of said printing apparatus at the top of its associated channel and at the other end thereof at the bottom of its associated channel and each band passing from its connection at said one end of the imprinting apparatus over and around one roller of its associated roller pair and then around and under the other roller of its associated roller pair and thence to said connection at the other end of said printing apparatus; and whereby an imprint is created whenever said roller platen is moved across said print bed.
Claim 3
Dependent Claim 56 words
Apparatus as in claim 1 where the bottom of said first and second channels are coplanar with the upper surface of said print bed whereby said first and second bands clamp said document onto said print bed during a printing operation and prevent the removal thereof until the roller platen is returned to an initial position.
Claim 4
Dependent Claim 53 words
Printing apparatus as in claim 1 where said roller platen is a sleeve and said means for moving said roller platen includes a shaft disposed within said sleeve and connected between vertical legs of said carriage, said shaft engaging the inner surface of said sleeve whenever the motion is imparted to said carriage.
Claim 5
Dependent Claim 16 words
Apparatus as in claim 3 where said shaft is rotatably mounted with respect to said carriage.
Claim 6
Dependent Claim 21 words
Apparatus as in claim 4 where the inner diameter of said sleeve is approximately 2 times the diameter of said shaft.
Claim 7
Dependent Claim 38 words
Apparatus as in claim 1 where said first and second bands are respectively movably connected with respect to said one end of said imprinting apparatus whereby variations in thicknesses of documents, printing plates and/or embossings may be compensated.
Claim 8
Dependent Claim 26 words
Apparatus as in claim 6 including two springs respectively connected between the ends of said bands and said one end to thereby effect said movable connection.
Claim 9
Dependent Claim 85 words
Printing apparatus as in claim 1 where said print bed is provided with a recess for receiving a printing plate, the depth of which is greater than the thickness of the printing plate body but less than the total thickness of said plate and where said roller platen is disposed immediately above said print bed whereby only the roller platen and the raised characters coact during a printing operation and not the body of the plate to thereby eliminating smudging originating from the plate body.
Claim 10
Dependent Claim 23 words
Apparatus as in claim 8 where the depth of said recess is approximately 0.005 inch greater than the thickness of said plate body.
Claim 11
Dependent Claim 14 words
Apparatus as in claim 1 including an ink roller disposed about said roller platen.
