PROBLEM TO BE SOLVED: To improve detachability of a heat pipe, and prevents cooling air from leaking to the outside.SOLUTION: In a sheet cooling device for cooling a sheet with a heat pipe 71, a heat radiation unit 72 provided at an end of the heat pipe 71 is included in an air duct 76, and an openable/closable lid member 77 that opens a direction for the heat pipe 71 to be attached or separated to/from the sheet cooling device is provided to a duct 76. Accordingly, the lid member 77 is opened to achieve easy attachment and detachment of the heat pipe 71. When the lid member 77 is closed, leakage of air from the inside of the duct is prevented. |
