Apparatus for pulling bills and checks in bundle bill and check acceptor
An apparatus for pulling a paper medium, e.g., a bill or a check in a bundle bill and check acceptor includes a transfer roller unit transferring the paper medium that is vertically introduced into a storage cassette, a transfer belt unit provided to be rotated so that the paper medium that has passed through the transfer roller unit is horizontally transferred to a rear of the storage cassette, and a clamping roller unit having first and second elastic clamps. Each of the clamps is configured to clamp and pull the front end of the paper medium, and release the paper medium at the rear of the storage cassette depending on rotation of the transfer belt unit, so that the paper medium is stacked in the storage cassette.
1. An apparatus for pulling a bill or a check into a storage cassette of a bundle bill and check acceptor, comprising:
a transfer roller unit configured to vertically transfer a paper medium into an inlet port of the storage cassette;
a transfer belt unit comprising a transfer belt and a stack wheel, the transfer belt configured to horizontally transfer the paper medium to a rear portion of the storage cassette, the transfer belt formed with at least two holes;
a clamping roller unit configured to clamp a front end of the paper medium vertically transferred through the inlet port depending on movement of the transfer belt unit, the stack wheel configured to strike a rear end of the clamped paper medium; and
elastic clamps provided on the transfer belt at positions spaced apart from each other by a predetermined distance, each of the elastic clamps configured to open an end to clamp and pull the front end of the paper medium vertically introduced through the inlet port when each of the elastic clamp is passing through the clamping roller unit, each of the elastic clamps further configured to release the paper medium at the rear portion of the storage cassette to stack the paper medium on top of another paper medium in the storage cassette; and
a prism sensor unit including a light emitting part and a light receiving part, the light emitting part and the light receiving part located relative to the at least two holes of the transfer belt to detect locations of the elastic clamps relative to the clamping roller unit.
2. The apparatus of claim 1 , wherein the transfer belt unit comprises a separation stopper configured to block the front end of the paper medium for release at the rear portion of the storage cassette to cause the paper medium to drop into the storage cassette.
3. The apparatus of claim 1 , wherein when the paper medium is clamped by one of the elastic clamps, a subsequent paper medium waits for transfer by the transfer roller unit.
4. The apparatus of claim 1 , further comprising:
a detecting sensor provided between the transfer roller unit and the clamping roller unit, the detecting sensor configured to detect entrance of the paper medium into the storage cassette.
