Is configured to.

[Problems to be Solved by the Invention]

However, in the conventional text-writing / printing device, the printing paper is bent and folded back in the printing section, so when the device is further miniaturized, the radius of curvature of the curved paper feeding path becomes small, and it becomes like a postcard. There is a problem that printing of thick thick printing paper becomes difficult.

On the other hand, as described in Japanese Examined Patent Publication No. 60-131272, there has been proposed one in which a printing sheet is taken in and out from a platen in a horizontal direction. However, even in this print output device, since the front end of the print paper supplied from the table on the front side is curved by the curved conveyance unit on the rear side of the print unit, it is difficult to print on the thick print paper. Come on. If the configuration described in Japanese Utility Model Laid-Open No. 63-31948 is adopted, it is possible to print without curving the printing paper, but when the printing unit is not used or when printing thin paper. Occasionally, half of the printing unit must be stored in the main body case in a state of being tilted so as to be parallel to the horizontal axis, which inevitably increases the size of the main body case and increases the installation floor area of the apparatus.

An object of the present invention is to provide a text creation / printing apparatus capable of printing without curving the printing paper and reducing the installation floor area.
