Problems solved by technology

In this printer, when the paper starts to be conveyed by the platen roller, the paper conveyed on the platen roller tends to slip due to the inertial load of the winding portion of the paper held by the paper holding portion, which sometimes leads to a decrease in print quality

Embodiment Construction

[0015] According to the embodiments described herein, a printer includes a paper holding portion, a print conveyance portion, a buffer portion, and a movable portion. The paper holding portion holds the paper 2 wound in a roll so that it can be drawn out and conveyed. The print conveying section is provided with a print head and a platen roller arranged opposite to each other, the print conveying section pulls out and conveys paper and then prints on the paper. The buffer portion is arranged on the downstream side of the paper holding portion in the paper conveying direction and on the upstream side of the printing conveying portion in the paper conveying direction to elastically press the paper surface of the paper. The movable part equipped with the print head and buffer is rotatable between a closed position opposite the print head and the platen roller, and an open position between the print head and the platen roller and an open position width.

Abstract

A printer comprises a paper holding section, a printing and conveying section, a buffer section and a movable section. The paper holding section holds the paper rolled into a roll such that can draw out and convey the paper. The printing and conveying section, which is provided with a print head and a platen roller that are arranged opposite to each other, draws out and conveys the paper and then prints on the paper. The buffer section arranged at the downstream side of the paper conveying direction of the paper holding section and the upstream side of the paper conveying direction of the printing and conveying section to elastically press the paper surface of the paper.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2011-193002 filed on September 5, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The embodiments described herein relate to a printer. Background technique [0004] Generally, there is known a printer that pulls out and conveys roll-shaped paper held by a paper holding portion using a platen roller and then prints on the paper. In this printer, when paper starts to be conveyed by the platen roller, the paper conveyed on the platen roller tends to slip due to the inertial load of the winding portion of the paper held by the paper holding portion, which sometimes leads to a decrease in print quality. [0005] In order to suppress the reduction in print quality, a printer equipped with a buffer portion that presses the paper pulled out from the paper holding portion using a propping mem...
