Abstract

A system for storing and electronically monitoring the locations of keys and other articles, and providing a printed record of transactions involving the stored articles. The articles are held on digitally coded article holders which are stored on a storage panel and electronically scanned to determine the identity of the article at each storage location on the panel. When an authorized user of the system enters his user code and makes a request for one of the articles, an indication light is energized to indicate the location of the requested article. If the article is absent, the system displays the user code of the authorized user in possession of the missing article. A printer in the system operates to provide a printed record of which users removed and returned which articles at which times. An optional scale weighs articles such as pharmaceuticals to determine the weight of the contents that are removed.

Claims

1. Apparatus for storing and monitoring articles and maintaining a record of the articles, said apparatus comprising:

a plurality of article holders each holding one article and each having a unique identification code which identifies the article held thereby;

a storage member having a plurality of discrete storage locations for the articles, each storage location having a unique address and each storage location being adapted to receive and store the article holders one at a time;

means for accepting and recording valid user codes assigned to authorized users;

means for polling said storage locations to determine and update the identification code of the article holder at each location

an indicator on said storage member for each storage location, each indicator having an energized condition and a deenergized condition;

means for accepting coded requests corresponding to the identification codes of the article holders when the coded requests are accompanied by a valid user code;

means for energizing the indicator which corresponds to the storage location of each article holder whose identification code corresponds to an accepted coded request, thereby indicating the storage location of the article holder to which each coded request corresponds if the article holder is present on the storage member;

means for recording the user code accepted at the time each article holder is removed from the storage member;

means for displaying the user code accepted at the time an article holder was removed from the storage member if the article holder is not present on the storage member thereby identifying the user responsible for removing the article holder from the storage member;

printing means selectively operable to print a written record of the user codes accepted at the time one or more selected articles were removed from the storage member; and

means for weighing and recording the weight of each article holder before its removal from the storage member and prior to its return to the storage member, thereby recording the weight of material removed from the article holder while it was removed from the storage member.

2. Apparatus as set forth in claim 1, including means for recording the date and time each article holder is removed from the storage member and the date and time each article holder is returned to the storage member.

3. Apparatus as set forth in claim 2, wherein:

said printing means has a first mode of operation wherein is printed the identification codes associated with all article holders removed at the time a selected user code was accepted, and the date and time each such article holder was removed from the storage member and returned thereto; and

said printing means has a second mode of operation wherein is printed all user codes accepted at the time an article holder corresponding to a selected identification code is removed, and each date and time the article holder was removed from the storage member and returned thereto.

4. a method of storing and monitoring articles which are accessible to authorized users and maintaining a record of which users access the articles, said method comprising the steps of:

providing a storage panel having a plurality of discrete storage locations at which the articles may be stored;

storing the articles at the storage locations;

assigning to each article a unique identification code;

polling the storage locations periodically to determine the identification code of the article at each location;

assigning to each authorized user a valid user code;

accepting valid user codes and rejecting invalid user codes;

accepting coded requests which correspond to the identification codes only if the request is accompanied by a valid user code;

indicating the location of an article which corresponds to an accepted coded request;

recording the user code accepted at the time each article is removed from the panel;

determining the date and time each article is removed from the panel and returned thereto;

selectively printing a written record of the user codes accepted at the time one or more articles were removed from the panel, said record also containing the date and time each such articles was removed form the panel and returned thereto;

weighing each article after removal of same from the panel;

weighing each article before return of same to the panel to determine the weight of material removed while the article was absent from the panel; and

printing a written record of the weight of each article at the time of its removal from the panel and at the time of its return thereto.
