Abstract
A device for cooling a sheet includes a conveyance path for the sheet between a first unit and a second unit. The conveyance path is formed of guide plates arranged in an opposed manner and through which the sheet is conveyed. A cooling unit cools the sheet which passes through the conveyance path, the cooling unit including at least one fan that supplies cooling air generally along a sheet conveying direction. At least one slit is formed in each of the guide plates. At least one introduction wall extends from one of the guide plates and guides cooling air from the at least one fan through the at least one slit and into the conveyance path.

A device for erasing an image on a sheet comprising:
- a reading unit configured to read an image formed on the sheet;
- an erasing unit configured to erase the image formed on the sheet by heating the sheet;
- a conveyance path for conveying the sheet between the reading unit and the erasing unit, the conveyance path including guide plates arranged in an opposed manner, wherein one of the guide plates has at least one slit;
- a cooling unit configured to cool the sheet which passes through the conveyance path, the cooling unit including at least one fan that supplies cooling air generally along a sheet conveying direction;
- and
- at least one introduction wall extending from one of the guide plates and configured to guide cooling air from the at least one fan through the at least one slit and into the conveyance path.
A method for cooling a sheet comprising the steps of:
