<p>PROBLEM TO BE SOLVED: To prevent the heating temp. from becoming inaccurate and the operation of a heating means from becoming troublesome even in case sheets accommodated in a sheet accommodating means have absorbed moisture, compared with a conventional arrangement which involves such inaccuracy and troublesomeness because the user must manipulate manually the heating means sensuously for dehumidifying the sheets. SOLUTION: The invention comprises a sheet accommodating means 1 to accommodate sheets, a humidity sensing means 3 to sense the humidity of the sheets accommodated in the sheet accommodating means, an electric heating means 7 to heat the sheets, and a control means 2 to control the heating means 7. In accordance with the humidity sensed by the means 3, the control means 2 controls the heating temp. by increasing in steps the current to be fed to the heating means 7, thereby dehumidifying the sheets.</p> |
