DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a solenoid-operated door locking device used in paid lockers installed in train stations and the like.

(Prior Art) In conventional paid rental lockers, coin slots are individually provided in the fixed frame surrounding the box-shaped article storage section, and coins inserted through the slots are sorted by type using a coin sorter. When the amount is measured and coins of the correct amount are inserted, an unlocking signal is electrically or mechanically sent to the lock that locks the door of the goods storage section to the fixed frame, and the coins are received. The coins are stored in a coin storage container provided in the fixed frame portion.

(Problem to be Solved by the Invention) Since this coin storage container is individually equipped with a lock such as an axial pin tumbler lock, in conventional paid rental low-row 2 cars, two locks are attached to one article storage section. It was necessary to install a lock, which was expensive in terms of cost.

In addition, in order to prevent coins from being stolen from the coin storage container by illegally unlocking a single lock with a picking tool, etc., it is necessary to constantly monitor the location of the lock in each article storage section. It is actually impossible to monitor all the locks of the article storage compartments arranged in such a way because of personnel allocation, and monitoring with mechanical equipment such as a monitor television is also not cost-effective.

As a method for stealing coins with the minimum number of efficient staff allocations and monitoring equipment, the point for inserting money such as coins is only provided on the remote control machine installed in each paid locker. , a method is proposed in which the money storage container is limited to one location.

In this remote-controlled pay-to-rent locker, when a user inserts a certain amount of money into the operating machine, the user receives a card displaying the compartment number of the storage compartment designated by the user and the code number for unlocking. is fed out from the operating device, and at the same time, the door of the designated article storage section is electrically unlocked.

The user goes to the article storage section of the designated section displayed on the card, stores the articles such as baggage, and then closes the door and performs a predetermined locking operation.
