Publication number: 20090256872Abstract: A print head which prevents printing force from being reduced by making the distance between the tip of a printing wire and a printing medium adjustable, and a printer equipped therewith are provided. When the tip of a wire (11) abrades through use of a print head (1) and printing force is reduced due to an increase in a distance between the printing surface of a print sheet (20) and the tip of the wire (11), a pull-out spacer (14) is pulled out. As the pull-out spacer (14) is pulled out, a distance L2 between the tip of a trace roller (12) and a reference surface (16a) of a frame is shortened to L1?2t, and a distance between the printing surface of the print sheet (20) and the reference surface (16a) of the frame, which is equal to a distance L2, is also shortened.Type: ApplicationFiled: February 20, 2007Publication date: October 15, 2009Applicant: Seiko Precision Inc.Inventors: Yuichi Yamakawa, Naonobu Sawada

Patent number: 5320441Abstract: Printing wires are able to be changed over from one to another by the movement of a printing head alone, thereby eliminating the need for a solenoid and simplifying the arrangement. The printing quality is improved by uniformly guiding the printing wires with the entire circumference of each guide hole, and further the amount of torsion of the printing wires caused by changeover of the printing wire arrangements is equalized, thereby stabilizing the printing characteristics and eliminating the difference in the printing characteristics between the parallel and staggered arrangements and also improving the durability. A first front guide is secured to a nose portion of a head frame. A front guide supporting frame, which supports a second front guide, is provided on the nose portion of the head frame so that the frame is movable in the direction of alignment of the printing wires. The printing wires are guided by the second front guide and the first front guide.Type: GrantFiled: November 12, 1992Date of Patent: June 14, 1994Assignee: Seikosha Co., Ltd.Inventor: Yuichi Yamakawa
