A small-sized printer includes a printing section equipped with a shuttle head in which impact-type printing units are arranged in juxtaposition in a sub-scanning direction, a cylindrical cam for reciprocating the shuttle head in the sub-scanning direction, and paper feeding rollers for feeding a standard sheet in a main scanning direction; an input device for inputting information; a display device for displaying information; a RAM for storing information; and a CPU for controlling the printing section, the input section, the display device and the RAM and performing calculation on information. The printing section and the paper feeding rollers are provided in a body case in such a way as to be exposed where they are opposed to a case cover, which has a flat platen and spring members at positions opposed to the printing section, and ribs adapted to come into contact with the standard sheet and serving as a positioning device and as a sliding guide. The printing section provided in the body case has protrusions adapted to abut against the surface of the flat platen on the case cover. Spring members are provided to resiliently bias the flat platen against the protrusions, with a space being secured behind the flat platen.
