Abstract
In sheet separating apparatus suitable for use in an automated teller machine (ATM), sheets, such as banknotes, are removed singly from a stack (14) using reduced pressure derived from a vacuum pump (86). An air filter (72) is provided in the vacuum supply line (16) from the vacuum pump (86). A pressure sensor (68) senses the pressure in the vacuum supply line (16) and when this rises to a threshold value, causes the vacuum pump to supply reverse air flow through the air filter (72) to transport any dust particles impeding the operation of the air filter (72) to a dust collection container (106).
