A Hall detection device for a thickness of a sheet medium is provided, including a mounting rack, a reference shaft and a floating wheel assembly, wherein the floating wheel assembly includes a bracket and at least one floating wheel, one end of the bracket being mounted on the mounting rack via a floating wheel rotary shaft and the other end thereof being rotationally fitted with the floating wheel so as to form a free end, a torsional spring is provided between the floating wheel rotary shaft and the bracket so that the floating wheel elastically bears against the reference shaft, and the bracket is fixedly mounted with a detection block and a sensor for detecting a displacement amount of the detection block.

A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.

Described is a device for examining value documents and/or the transport of value documents which are transported along a specified transport path in a specified transport direction, by means of ultrasound with ultrasound transmitters disposed offset in a direction transverse to the transport direction for emitting, upon transmit signals, ultrasound on the transport path and ultrasound receivers disposed offset in a direction transverse to the transport direction for receiving ultrasound which is generated by means of the ultrasound transmitters, and for emitting receive signals, the ultrasound transmitters and/or ultrasound receivers respectively having at least one capacitive, micromechanical ultrasonic transducer.
