An actuating rod driving the print head to be close to or away from the paper feed roller in response to an opening/closing action of the cover is provided in the base. The actuating rod is configured to swing around a second axis parallel to the first axis, and is provided with an installation part suitable for mounting the print head and a drive part suitable for being driven by the cover.
