Abstract
A user does not have to observe the orientation of a supply-side film core and a roll-up-side film core, when placing them into a case. Shaft sections are disposed at both ends of the supply-side film core and the roll-up-side film core made of resins. The shaft sections have different diameters from each other. Each shaft section has a diameter corresponding to each supporting section. The user can therefore set the ink film in a predetermined position and orientation in the case as a single step.
Claims13
A printer transferring a contrast agent on a contrast agent film to paper comprising:
- a case;
- a supply-side film core including;
- a first film winding section winding the contrast agent film;
- a first shaft section disposed at a side of said first contrast agent winding section;
- and
- a first gear disposed at one end of said supply-side film core;
- a roll-up-side film core rolling up the contrast agent film from said supply-side film core, including;
- a second film winding section about which is wound the contrast agent film;
- a second shaft section disposed at a side of said second film winding section, said second shaft section having a different diameter than said first shaft section;
- and
- a second gear disposed at one end of said roll-up-side film core;
- and
- supporting sections disposed in said case, each of said supporting sections having a diameter corresponding to each diameter of said first and second shaft sections.
