Abstract
Abstract A printing position adjusting mechanism is disclosed for use in a printer of the type in which a printing head is carried on the leading end portion of a yoke and the row of types of the printing head is arranged in the longitudinal direction of the yoke. The printing position adjusting mechanism includes an externally threaded adjusting ring, which is screwed into the internally threaded hole formed in the front frame plate of the yoke, and its leading end face abuts the opposed leading end face of the yoke. This causes the printing head to be moved longitudinally of the yoke, thereby to adjust the printing position thereof relative to the yoke. For fixing the printing head at a desired printing position to the yoke, an internally threaded hole is formed in the leading end face of the yoke, and a fixing screw is inserted into a center hole through the adjusting ring and extends into the threaded hole in the yoke. Thus, the printing position can be adjusted reliably with ease merely by screwing the adjusting ring in the threaded hole in the printing head.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
191 words
Printing position adjusting mechanism for use in a printer, wherein the printer comprises: a platen; a yoke movable with respect to the platen toward and away from the platen, the yoke having a leading end portion with leading end faces thereon; and a printing head carried on the leading end portion of the yoke for moving together with the yoke with respect to the platen; the printing head having types supported thereon and facing toward the platen such that relative movement of the yoke toward the platen moves the types to the platen for printing an object then supported on the platen; the printing position adjusting mechanism comprising: an adjusting member supported on the printing head and movable with respect thereto in directions toward and away from the leading end faces of the yoke; the adjusting member having an abutment face opposed to the leading end faces of the yoke, whereby following selected movement of the adjusting member with respect to the printing head, the printing head can be adjusted in position with respect to the yoke until the adjusting member abutment face abuts the leading end faces of the yoke.
Claim 2
Dependent Claim
191 words
Printing position adjusting mechanism for use in a printer, wherein the printer comprises: a platen; a yoke movable with respect to the platen toward and away from the platen, the yoke having a leading end portion with leading end faces thereon; and a printing head carried on the leading end portion of the yoke for moving together with the yoke with respect to the platen; the printing head having types supported thereon and facing toward the platen such that relative movement of the yoke toward the platen moves the types to the platen for printing an object then supported on the platen; the printing position adjusting mechanism comprising: an adjusting member supported on the printing head and movable with respect thereto in directions toward and away from the leading end faces of the yoke; the adjusting member having an abutment face opposed to the leading end faces of the yoke, whereby following selected movement of the adjusting member with respect to the printing head, the printing head can be adjusted in position with respect to the yoke until the adjusting member abutment face abuts the leading end faces of the yoke.
Claim 3
Dependent Claim
64 words
The printing position adjusting mechanism of claim 1, wherein the yoke has a longitudinal direction of extension, and the leading end portion of the yoke is toward one end of the yoke; means for guiding the printing head to be adjustable along the longitudinal direction of extension of the yoke until the adjusting member abutment face abuts the leading end faces of the yoke.
Claim 4
Dependent Claim

Claim 13
Dependent Claim
34 words
The printing position adjusting mechanism of claim 10, further comprising fixing means for fixing the printing head to the yoke for preventing further adjusting movement of the printing head with respect to the yoke.
Claim 14
Dependent Claim
46 words
The printing position adjusting mechanism of claim 10, wherein the adjusting member is screw threadedly connected to the printing head in that the adjusting member has an externally threaded circumference and the printing head includes an internally threaded screw hole for receiving the adjusting member circumference.
Claim 15
Dependent Claim
34 words
The printing position adjusting mechanism of claim 10, further comprising a fastener extending from the adjusting member to the yoke for preventing further adjusting movement of the printing head with respect to the yoke.
