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 covers a first paper projection port through which paper as the printing medium is projected when the paper is inside a housing. This can prevent the entry of the dust through the first paper projection port to the housing. Furthermore, the first cover swings about a first engagement portion by pressure of a front end of the paper to cover the paper when the paper is projected through the first paper projection port in the forward feeding motion by the feeding device such as a paper feeding roller.

摘要： A connector, which enables the molding of narrow press-fitting grooves for cantilever contacts and has cantilever contact press-fitting grooves of a structure such that the molding dies for the grooves will have adequate strength and durability, is provided. In molding a rectangular first press-fitting groove 421, in which a first fixed part 5B of a cantilever contact 5 is press-fitted, a plurality of upper-face opened recess parts 42U, which are continuous with the first press-fitting groove 421, are molded by an upper die 1. Lower-face opened recess parts 42D, which are continuous with the first press-fitting groove 421, are molded by a lower die 2. By the combination of the upper die 1 and the lower die 2, the upper-face opened recess parts 42U and the lower-face opened recess parts 42D are formed in an alternating manner. The first press-fitting groove 421 is formed in an intermittent manner by the upper-face opened recess parts 42U and the lower-face opened recess parts 42D.
