ABSTRACT:
A printer with a mechanism for guiding paper has a lower casing having a printer body therein with a print head therein, an upper casing hingedly mounted on the lower casing for movement between a closed and an open position relative to the printer body, and the lower casing has a lower casing guide member and the upper casing having an upper casing guide member which is in spaced opposed relation to the lower casing guide member when the upper casing is in the closed position for defining between the guide members a paper guide path. The lower casing has a paper feeding opening for feeding a printing paper into the printer past the print head and over the lower casing guide member. The upper casing guide member is pivotally mounted on the upper casing for pivoting movement of the part of the upper casing guide member which is toward the paper feeding opening toward and away from the lower casing guide member. A spring is engaged with the upper casing guide member normally urging the upper casing guide member in a pivoting direction in which the part of the upper casing guide member which is toward the paper feeding opening is moved away from the lower casing guide member. A cam on the lower casing and the upper casing guide member, when the upper casing is moved from the open position to the closed position, pivots the upper casing guide member against the action of the spring to a position, when the upper casing is in the closed position, in which it is in the spaced opposed relation to the lower casing guide member for defining the paper guide path.
