Abstract
An electric locker apparatus to be installed at a public space, such as entrance hall of a condominium, includes a plurality of locker boxes of at least one type, each having a door with an electric lock device, and a sensor for detecting whether the relevant locker box is occupied by an article or empty. An improved locker box designating device serves to automatically designate an empty locker box of a desired type such that any one of the locker boxes of a same type, after it has been once used, can be designated only after subsequent one-round use of all remaining locker boxes of the same type. The lock device of the designated locker box is actuated to unlock the door, for allowing an article to be accommodated in the locker box. All the locker boxes of a same type are thus put into use with as uniform a frequency as possible.
