PROBLEM TO BE SOLVED: To improve drainage performance without expanding the dimensions of an overflow tank. SOLUTION: A slit-like auxiliary watershoot 60 is provided so as to communicate with an excess liquid watershoot 52 provided at a side adjacent to the drying part 22 of a rinse tank 24C. The drainage performance to discharge an excess liquid is reliably secured without expanding the dimensions of a unit or extending the transporting path even when the unexpected excess liquid occurs from a side wall 54 at the side of the drying part 22 because the volume of the excess liquid watershoot 52 is significantly increased. Thereby, a box 62 in which the electrical parts and the control instruments of the drying part 22 are housed is protected from washing water. In the auxiliary watershoot 60, a space part 58 almost usually serves as airspace, thereby substitutes for a heat insulating material, and prevents the dew condensation of the rinse tank 24C.
