Claims

[Scope of utility model registration request]

There is an endless document transport belt that is installed on the document placement glass and rotates to transport the document to and from the document placement glass, and an endless document conveyance belt that transports the document to and from the document placement glass. A document leading edge detection sensor that detects the leading edge of the document is connected to a rotational drive source for the document transport belt, and a drive transmission relationship from the rotational drive source to the document transport belt, and the document leading edge detection sensor detects the leading edge of the document. A clutch whose drive transmission relationship is disconnected by a clock pulse generated after detecting a clutch is turned on when a predetermined number of clock pulses are counted after a period of time after the disconnection.
An automatic document feeder for a copying machine, comprising a brake mechanism for completely stopping a document conveyance belt.
