In a recording apparatus employing a magnetic linear encoder that includes a magnetized scale and a magnetic head movable along the scale, in order to enable efficient mounting of the scale on the recording apparatus and to enable tension adjustment of the scale, support members are provided for detachably supporting the scale, as is a device for providing tension during the mounting of the scale on side plates of the recording apparatus. Also, the magnetized portion of the scale is positioned behind the carriage. Further, the magnetic head is provided with dust shield members which are in contact with, but rendered slidable with respect to, the scale.

Recording apparatus provided with a magnetic encoder for a scanning

A recording apparatus, which is provided with a carriage supporting a recording head or reciprocating along a platen, includes a magnetized scale of a magnetic linear encoder positioned along a moving direction of the carriage, and a magnetic head of the magnetic linear encoder, mounted on the carriage and adapted for reading the magnetized pattern of the scale. The scale is provided with at least two magnetized lines of mutually different pitches of magnetization, for recording position information relating to the recording operation, and position information relating to other functions.
