To obtain a washing storing device capable of previously preventing the generation of mischief on washing or theft of washing.

The washing storing device for unlocking a charging door when a user inserts a member's card, and after charging washing from a charging port, locking the door to store user's washing is constituted of a door open/ close sensor 7 for detecting the opened/closed state of the door, a buzzer for generating a check sound when the member's card or the like is inserted and a control means for driving the buzzer so as to generate an alarm sound when a door open signal is inputted from the sensor 7 in the locked state of the door. Since the buzzer is continuously driven to generate an alarm sound when mischief is done on washing or the washing is stolen, action such as mischief on the washing can be stopped.
