A note acceptor security system includes a currency validator secured to a housing and a note stacker removably received thereby. The currency validator has an identification chip maintained in association therewith and having a fixed serial number. The currency validator also includes a microprocessor which controls the operation of the currency validator and maintains operational data respecting the same. The stacker has a memory chip which is urged into a grounded position which is removed when the stacker is placed into the note acceptor. A fixed probe within the note acceptor lifts the memory chip from ground and allows communication from the microprocessor and identification chip to the memory chip. When the stacker is full, it is removed from the note acceptor and, with the memory chip grounded, it is transported to a docking station where the memory chip is again probed and the data maintained therein is transferred to a personal computer for later use. The memory chip is then erased and the stacker made available for reuse.

Note acceptor security system

Apparatus for performing tests for determining the validity of a paper purported to be a valid instrument is presented. Fundamentally, the invention comprises a tray for receiving a paper offered as a valid instrument and maintaining the same in sliding relationship between a light source and reticle. A photocell is operatively connected to the reticle and senses light passing from the light source and through the paper and reticle. The output of the photocell is applied to an operational amplifier having a dynamic feedback network and the output of this amplifier is characteristic of both a grid pattern upon the paper and the optical density thereof. This output is then passed to an amplifier circuit which establishes an optical density domain and is operative to pass a signal only if the paper falls within such domain. This output is then passed to appropriate integrating and comparator circuitry to ultimately determine the validity of the paper.

Logarithmic primary testing system for security validation

A note storage apparatus has a stacking assembly, a push bar assembly movably mounted in the stacker, a coffer assembly for storing the notes, a collector located in the stacker assembly for receiving the notes and the push bar assembly selectively contacting the note and transferring it to the coffer assembly.

Note storage apparatus

Disclosed is a coin and currency changer utilizing a coin chute having two continuously intersecting arms wherein coins may be alternately stored. A plunger assembly is positioned at the bottom of the chute along the line of intersection of the two arms and is operative to dispense one coin at a time therefrom. The coin in the chute immediately above the dispensed coin is retained within the chute by a pinching action between the plunger assembly and the structure of the chute. A sensor is positioned in operative relation with the plunger assembly and senses the actual dispersal of the coins from the chute. Control circuitry counts the number of coins dispensed and is operative to inhibit functioning of the system if more than the desired number of coins is actually dispensed. There is further provided means for maintaining a proper number of coins within the chute by transferring the coins from a bulk hopper to the chute. Further, the combination of change dispensable by the changer is pre-programmable by a serviceman or alternately could be customer selected or controlled by data computed according to the requirements of any transaction which requires a flexible amount of change.
