Abstract

Claims (16)

1. A media dispenser comprising:

a pick unit arranged to pick individual sheets under control of a pick unit motor;

a transport section arranged to transport each picked sheet;

a stacker wheel arranged to collate transported sheets under control of a stacker wheel motor; and

a controller including a counter, the controller being arranged to (i) enable selectively the pick unit motor and the stacker wheel motor, (ii) provide a first step signal to both the pick unit motor and an input to the counter, and (iii) provide an output from the counter as a second step signal to the stacker wheel motor.

2. A media dispenser according to claim 1 , wherein the value of the counter is related to a required gearing between the pick unit motor and the stacker wheel motor.

3. A media dispenser according to claim 1 , wherein the sheets comprise banknotes.

4. A self-service terminal including the media dispenser of claim 1 .

5. A self-service terminal according to claim 4 , wherein the self-service terminal comprises an automated teller machine.

6. A method of controlling a media dispenser comprising:

(i) selectively enabling each of a pick unit motor and a stacker wheel motor, and moving each motor to its respective reset position;

(ii) providing a first step signal to both the pick unit motor and an input to a counter, and

(iii) providing an output from the counter to the stacker wheel motor as a second step signal.

7. A method according to claim 6 , wherein the method comprises the further step of repeating the steps until all requested sheets have been picked and presented to a customer.

8. A method according to claim 6 , wherein the method further comprises loading a first value into the counter so that one pulse for the second step signal is generated when the first value has been decremented to zero; and loading a second value, different from the first value, into the counter so that another pulse for the second step signal is generated when the second value has been decremented to zero.

9. A method according to claim 6 , wherein the method further comprises incrementing the counter until a first value is reached so that a pulse for the second step signal is generated when the first value has been reached; resetting the counter; and incrementing the counter again until a second value is reached, different from the first value, so that a pulse for the second step signal is generated when the second value has been reached.
