A machine tool having a drive motor includes an electronic unit and a switch for switching the drive motor on/off. An additional contact module is connected to the electronic unit, the drive motor being electrically connected only to the contact module. Also, the switch is connected to the contact module.

A digital printer or copier machine () is proposed for the single-sided or double-sided printing of a substrate (), with at least one fixing device () for fixing toner onto the substrate (), whereby the fixing device () has at least one heating device for fusing the toner. The machine has, in addition, at least one transport device (), in order to supply the substrate () to the heating device, to guide it past the heating device and/or to further transport it from the heating device, whereby the transport device () has at least one suction belt () that is provided with a number of through-passage openings () and can be impinged with a vacuum. The machine () is characterized in that the suction belt () is constructed as a mesh.

A device for balancing eccentricity of a spindle drive () to avoid blocking of the spindle drive during lifting movement of a platform (), in which the platform is mounted on several axiparallel spindles (G; G; G; G) by bearing devices (L; L; L; L) arranged on it and can be lifted together with the bearing devices axially along the spindle. The spindle drive () has at least three axiparallel, rotatable threaded spindles (G; G; G; G) with bearing device (L; L; L; L) in a polygonal arrangement; low-friction bearing devices (L; L; L; L) with radial bearing clearance (F; F) are arranged to balance the radial eccentricity of the rotating threaded spindles so that a relative radial movement of the rotating spindles to platform () is possible with limited force expenditure.

A device (I) for separating an uppermost sheet (S ) from a supply stack (S), for the purpose of grasping the separated uppermost sheet and feeding it, wherein air blowers ( ) for spreading apart several sheets of an upper sheet stack area (SR) and air blowers ( ) for separating the uppermost sheet (S ) and holding back an adhering sheet (S ), are located downstream in front of the supply stack and transverse to a sheet transport path ( ), and wherein air jets with different pressures, directions, and diameters may be generated by the air blowers ( ) supplied from an air pressure source ( ) with at least one air nozzle ( ) located in the area of a center line (Y, Z) of the stack ( ) and the transport path ( ) and with several air nozzles ( ) located on both sides of the center line.
