Abstract
Abstract A method for manufacturing a wire printer head comprises providing a wireguide block comprised of a print wire, a hilt connected to the rear end portion of the print wire, a guide tube for guiding the print wire, a return spring for pushing the hilt rearward, a guide pipe for guiding the hilt, and a support plate having a hole therein in which is loosely fitted the guide pipe; and providing a wire driving block comprised of a lever for impacting the hilt, and an electromagnetic driving device for actuating the lever. The wire guide block is first connected to the wire driving block with the hilt directly contacting the lever; then the guide pipe is urged into contact with the hilt by a force weaker than that of the print wire return spring; and then an adhesive is applied to adhere the guide pipe within the support plate hole.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A method for manufacturing a wire printer head which comprises: providing; a wire guide block comprising, a print wire, a hilt connected to the rear end portion of said print wire, a guide tube for said print wire, a return spring for pushing said hilt rearward, a guide pipe for said hilt and a support plate provided with a hole in which said guide pipe loosely fits, and a wire driving block comprising, a lever for impacting said hilt, and an electromagnetic driving means for actuating said lever: connecting said wire guide block to said wire driving block with said hilt directly contacting said lever: contacting said guide pipe to said hilt by a pushing means whose force is weaker than that of said return spring: and spreading adhesive agent to the engaged portion between said guide pipe and said hole thereby fixing said guide pipe to said support plate in said hole.
