摘要： A portable printer comprises a base and a cover covering the top of the base. A print head arranged in a vertical direction and a paper feed roller provided opposite to the print head are provided in the base. The paper feed roller rotates about a first axis. The paper feed roller conveys recording paper by rotating in the state that the recording paper is clamped between the paper feed roller and the print head. 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.
