Abstract
Abstract A control system of a coin-operated locker or a rental locker which comprises coin detector detecting the insertion of coins into a coin inlet slot of the locker, a first counter for counting the number of coins detected by the coin detector, a second counter operating stepwise in correspondence to the completion of one operation of the locker, that is, from locking to unlocking of the locker and to the lapse of time, and a keyoperation locking device enabling the locker to be locked or unlocked only when output signals from the first and second counter correspond to each other, whereby unlike conventional rental lockers, it is not necessary to reset all of the control circuits thereof to their original or initial condition whenever the door of the locker is opened to take a piece of baggage or the like out of the locker.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
43 words
A control system of a coin-operated locker, said system comprising: coin detector means for detecting the insertion of coins into a coin inlet slot of the coin-operated locker; first counter means for counting the number of coins detected by said coin detector means;
Claim 2
Dependent Claim
43 words
A control system of a coin-operated locker, said system comprising: coin detector means for detecting the insertion of coins into a coin inlet slot of the coin-operated locker; first counter means for counting the number of coins detected by said coin detector means;
Claim 3
Dependent Claim
109 words
A control system of a coin-operated locker as claimed in claim 1 which further comprises: a plurality of AND gates receiving counting output signals of said first counter means and counting output signals of said second counter means and operated by the logical sums of the counting output signals of the first counter means and the counting output signals of the second counter means thereby to produce output signals therefrom; and an OR gate operated by the logical sum of the output signals from the AND gates thereby to produce output signals permitting the key of the coin-operated locker to be turned for locking and unlocking the coin-operated locker.
Claim 4
Dependent Claim
73 words
A control system of a coin-operated locker as claimed in claim 1 in which said first and second counter means comprise rotary switches, respectively, count terminals of the rotary type switches being connected correspondingly to one another, and the combination of the first and second counter means are connected in series to an electromagnetic means which enables the key of the coin-operated locker to be turned for locking and unlocking the coin-operated locker.
Claim 5
Dependent Claim
151 words
A control system of a coin-operated locker as claimed in claim 1 which further comprises detecting means for detecting the completion of one operation of the coin-operated locker from locking the coin-operated locker to unlocking the same, said detecting means comprises: a first gate means for producing a setting signal by receiving both a signal of detection of a key-turning operation for locking the coin-operated locker and a signal of detection of a key-removing operation after locking of the coin-operated locker; a seond gate means for producing a resetting signal by receiving both a signal of detection of a key-inserting operation and a signal of detection of a key-turning operation for unlocking the coin-operated locker; a bistable memory which flip-flops by receiving each of the setting and resetting signals, and a pulse generating device which generates pulses when the bistable memory is changed from its setting conditions to its resetting conditions.
Claim 6
Dependent Claim
39 words
A control system of a coin-operated locker as claimed in claim 1, wherein said locking and unlocking detector means comprises a switch for detecting a key-turning operation and a switch for detecting the insertion and removal of the key.
