Claims

[Scope of utility model registration request]

In a printer in which a roll of printing paper is fed so as to be rolled up from below a platen, and printing is performed while feeding the fed printing paper upward, there is a space between the roll of printing paper and the platen. In order to prevent the printing paper from being re-engulfed from the paper feeding direction, the leading end portion of the printing paper is arranged so that it can contact the upper surface of the printing paper that exists between the rolled printing paper and the platen. A printer characterized by comprising an entrainment prevention body 20 disposed facing in a direction opposite to the direction in which paper is fed to a platen.
