A shutter control mechanism for controlling the movement of a pivoted shutter (20) suitable for controlling the passage of a user's card (6) in a self-service terminal (10) such as an ATM (automated teller machine), for example, includes a rotatable cam (23) having a cam track (24) which cooperates with a pin (30) on the shutter (20). Rotation of the cam (23) causes the pin (30) to move in the cam track (24) thereby causing the shutter (20) to pivot to open and close the card passage (2) alternately. Thus, the shutter (20) is held positively both in the open and in the closed position. <IMAGE> |
