An image generating apparatus includes a print portion printing a paper, a platen roller arranged so as to be opposed to the print portion, a heat radiating member mounted on the print portion, radiating heat generated in the print portion, integrally provided with a plate-like support shaft as an axis of rotation and rotatable in a direction for coming into pressure contact with or separating from the platen roller, a regulating member regulating movement of the print portion in a printing direction of the paper, a chassis having a hole-shaped bearing receiving the plate-like support shaft, and a side plate mounted on the chassis.

Image generating apparatus

In this image generating apparatus, a driving gear portion is so formed that the diameter of the outer peripheral surface of a first toothless portion is smaller than the tip diameter of a first toothed portion, and so arranged that the first toothless portion thereof slides on a second toothed portion of a driven gear portion of a print head rotating member in the vicinity of a position where a print head presses a platen roller with a pressing portion.

This paper feed mechanism includes a paper feed cassette integrally having a paper contact portion on a position deviating from the center of a rear-side inner wall surface in the cross direction by a prescribed distance in the cross direction and an apparatus body mountable with the paper feed cassette, and the apparatus body includes a driving portion rotating a paper feed roller in a paper feed direction and a paper discharge direction and a control portion bringing the rear end of the paper into contact with the paper contact portion for generating torque for the paper and thereafter transporting the paper to the apparatus body in paper feeding.
