Abstract

Abstract The printer has a printer frame, at least a printing head, a platen and a paper guide. The platen is formed integrally with a frame body in which the paper guide is incorporated so as to form an assembly separate from the printer frame, while the printing head is arranged in the printer frame. The frame body is adjustably secured to the printer frame so that the proper relative positioning between the printing head and the platen is ensured without impairing the guiding operation of the paper guide.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 255 words
A printing device having a printer frame, at least a printing head, a platen arranged in facing relationship to said printing head so as to cooperate therewith for a printing operation, and a paper guide for guiding and feeding a paper sheet to be imprinted between said printing head and said platen, the improvement comprising a frame body formed integral with said platen and said paper guide, said printing head being movable in said printer frame, said frame body forming with said paper guide an assembly assemblable independently of said printer frame, a shaft extending through said frame body and said printer frame, and wherein said frame body is swingably supported in said printer frame by said shaft, said frame body having at least a recessed portion at an end thereof adjacent to an inner wall of said printer frame and remote from a position at which said shaft extends through said frame body, at least a lever having a shaft-proximal end being supported at said proximal end by said shaft between said inner wall of said printer frame and said end of said frame body, said lever having an arm engageable in said recessed portion of said frame body, whereby the position of said platen relative to said paper guide is maintainable upon adjustment of the position of said platen with respect to said printing head without impairing the paper sheet guidance of said paper guide, and the adjustment of the angular position of said frame body is facilitated by manipulation of said lever.
Claim 2
Dependent Claim 255 words
A printing device having a printer frame, at least a printing head, a platen arranged in facing relationship to said printing head so as to cooperate therewith for a printing operation, and a paper guide for guiding and feeding a paper sheet to be imprinted between said printing head and said platen, the improvement comprising a frame body formed integral with said platen and said paper guide, said printing head being movable in said printer frame, said frame body forming with said paper guide an assembly assemblable independently of said printer frame, a shaft extending through said frame body and said printer frame, and wherein said frame body is swingably supported in said printer frame by said shaft, said frame body having at least a recessed portion at an end thereof adjacent to an inner wall of said printer frame and remote from a position at which said shaft extends through said frame body, at least a lever having a shaft-proximal end being supported at said proximal end by said shaft between said inner wall of said printer frame and said end of said frame body, said lever having an arm engageable in said recessed portion of said frame body, whereby the position of said platen relative to said paper guide is maintainable upon adjustment of the position of said platen with respect to said printing head without impairing the paper sheet guidance of said paper guide, and the adjustment of the angular position of said frame body is facilitated by manipulation of said lever.
Claim 3
Dependent Claim 178 words
A printing device having a printer frame, at least a printing head, a platen arranged in facing relationship to said printing head so as to cooperate therewith for a printing operation, and a paper guide for guiding and feeding a paper sheet to be imprinted between said printing head and said platen, the improvement comprising a frame body formed integral with said platen and said paper guide, said printing head being movable in said printer frame, said frame body forming with said paper guide an assembly assemblable independently of said printer frame, a plurality of fastener means for securing said frame body to said printer frame, and wherein the latter is formed with a plurality of holes for said frame body to be pivotably and adjustably secured to said printer frame by said fastener means slidably passing through said holes, respectively, whereby the position of said platen relative to said paper guide is maintainable upon adjustment of the position of said platen with respect to said printing head without impairing the paper sheet guidance of said paper guide.
Claim 4
Dependent Claim 178 words
A printing device having a printer frame, at least a printing head, a platen arranged in facing relationship to said printing head so as to cooperate therewith for a printing operation, and a paper guide for guiding and feeding a paper sheet to be imprinted between said printing head and said platen, the improvement comprising a frame body formed integral with said platen and said paper guide, said printing head being movable in said printer frame, said frame body forming with said paper guide an assembly assemblable independently of said printer frame, a plurality of fastener means for securing said frame body to said printer frame, and wherein the latter is formed with a plurality of holes for said frame body to be pivotably and adjustably secured to said printer frame by said fastener means slidably passing through said holes, respectively, whereby the position of said platen relative to said paper guide is maintainable upon adjustment of the position of said platen with respect to said printing head without impairing the paper sheet guidance of said paper guide.
