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 station premises and the like.

(Prior art) In conventional paid lockers, hard loan slots are individually provided in the fixed frame surrounding the box-shaped article storage section, and coins inserted through the slots are collected by a coin sorter. When the type and amount of coins are measured and the correct amount of coins is inserted, an unlocking signal is sent electrically or mechanically to the lock that locks the door of the goods storage section to the fixed frame, and the coin is 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 lockers, two locks are attached to one article storage section. It was necessary to attach a

In addition, in order to prevent coins from being stolen from the coin storage container by illegally unlocking the lock with a picking tool, etc., it is necessary to constantly monitor the location where the lock is installed in each article storage section. It is practically impossible to monitor all the locks of the article storage compartments arranged in the same manner from the viewpoint of personnel allocation, and it is not cost-effective to monitor them using mechanical equipment such as monitor televisions.

A method for stealing coins with the minimum amount of efficient staffing and monitoring equipment is to provide a place to insert money such as coins only on the remote control machine installed in each paid rental locker. A method is proposed in which the money storage container is limited to one location.

In this remote-controlled pay rental locker, when a user inserts a predetermined amount of money into the operating machine, a card displaying the compartment number of the storage compartment designated by the user and the code number for unlocking is operated. 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. When taking out an article, the user inputs a specified password number by operating the keys on the operating device, and sets the locking device of his/her article storage section to an unlocking standby state. Thereafter, the user goes to the article storage section and performs a predetermined unlocking operation to open the door.

The purpose of the present invention is to make it ideal for use in such remote-controlled paid rental lockers, and to be able to close the door by manual operation of a separate system even in the event of a power outage or failure of the device's electrical system.
