ABSTRACT:
A document shredder standing on a subframe has an outlet opening from which comminuted material falls into a basket. A swingably mounted flap loaded resiliently by a knee lever mechanism serves simultaneously as a full condition sensor against overfilling of the basket and as a closure for the outlet opening and in both these positions switches the document shredder off. It is brought from the closure position to the working position automatically on sliding in the basket, and on its removal into the closed position again.
