Cross-channel interference can be a problem in multi-channel switched power systems. Data, such as vehicle data from a vehicle diagnostic system, is stored in the memory. The patterned layer, due to a large index difference with the active layer andor variations of a refractive index between the mask and materials filling holes in the mask, acts as an optical confinement layer, a mirror, a diffraction grating, a wavelength selective element, a beam shaping element or a beam directing element. The registration system aligns sheets going to an imaging unit. The vibrating section varies the vibration of the touch panel depending on whether or not the reproduction position which has been changed through the user operation detected by the touch panel is a specified reproduction position. It is proposed that the gear element that is axially displaceable relative to the housing is interconnected via a longitudinal guide with a rotor or a motor shaft of the electric motor in a fashion that is torsion-resistant but axially displaceable, and acts on the throwout bearing via an actuator.
