Ink jet printer

摘要

The ink jet printer is provided which eliminates play between a carriage supporting an ink jet head and a guide shaft, allows the ink jet head to be releasably attached to the carriage, and provides reliable electrical connection between the ink jet head and the carriage with a reduced number of parts. An embodiment of the ink jet printer of the invention includes a guide shaft extending in a direction orthogonal to a direction in which paper is forwarded. A carriage is slidably mounted on the shaft, moving in reciprocal directions while being guided by the guide shaft. An ink jet head, releasably attached to the carriage, prints ink dots on the paper for forming a printed image by jetting ink out of nozzles. A first electrically connecting portion is arranged on the carriage. A second electrically connecting portion is arranged on the ink jet head so as to come in pressure contact with the first electrically connecting portion. A biasing member provides a pressing force between the first electrically connecting portion and the second electrically connecting portion.
