Abstract

In an electromotorically driven apparatus with an apparatus component which can be driven by a drive element and which performs a reciprocating vibratory movement, strip-shaped integral hinges are provided for the parallel guidance of said apparatus component. To increase the life of the integral hinges, at least one spring which exerts a force component in the direction of the vibratory movement is provided for each of the integral hinges.
