Abstract
A guard device for a postage meter, in particular protects an operator upon reaching into a mail feed mechanism for feeding letters that are inclined slightly to the rear and stand on one edge in a guide gap. The mail feed mechanism includes a revolving conveyor belt and contact-pressure elements secured thereto. Covering hoods are provided in a lateral deflection region of the conveyor belt. The risk to the operator is prevented even upon using the postage meter incorrectly by providing a side wall part of the covering hood in an exit region from the guide gap. The side wall part is easily released with the force of a finger and is coupled with a safety switch that short-circuits a motor which drives the conveyor belt if the side wall part is removed. A finger that becomes caught is thus released and the conveyor belt is stopped in an accelerated manner because of the effect of counter-inductance.
