Printer with dust protection

摘要

It is intended to provide a printer which can prevent dust from entering and adhering to a printing medium, thereby avoiding entry of the dust to or near a print head, and can improve print quality. A first cover (12) covers a first paper projection port (19) through which paper (10) as the printing medium is projected when the paper (10) is inside a housing (7). This can prevent the entry of the dust through the first paper projection port (19) to the housing (7). Furthermore, the first cover (12) swings about a first engagement portion (9) by pressure of a front end (10A) of the paper (10) to cover the paper (10) when the paper (10) is projected through the first paper projection port (19) in the forward feeding motion by the feeding device such as a paper feeding roller (56).
