An oscillator device includes a first oscillator, a second oscillator configured to support the first oscillator for torsional rotation about a first rotational axis, through a first torsion spring, a supporting member configured to support the second oscillator for torsional rotation about a second rotational axis, through a second torsion spring, the second rotational axis having a predetermined angle with respect to the first rotational axis of the first oscillator, a coil disposed in relation to the second oscillator, an electrical current applying member configured to apply an electrical current to the coil, and a magnetic field generating member configured to apply a magnetic field to the coil. The coil is localized in at least one of zones of the second oscillator being quartered by extension lines of the first and second rotational axes.

An oscillator device includes a supporting base plate, a supporting member, a movable plate supported by the supporting member for oscillating motion relative to the supporting base plate, a first functional device having a first function, a second functional device having a second function, a first wiring connected to the first functional device and formed on a first surface of the supporting member, and a second wiring connected to the second functional device and formed on a second surface of the supporting member different from the first surface thereof where the first wiring is formed, such that the width of the wirings on the supporting member can be made wide.

Oscillator device and image forming apparatus using the same

To provide an electric potential measuring device which is useful in realizing size reduction, high sensitivity, and high reliability. The electric potential measuring device includes: an oscillating device which includes torsion springs, and an oscillating body axially supported by the springs to oscillate; and signal detecting unit which is located on a surface of the oscillating body. A capacitance between the detection electrode and a surface of an electric potential measuring object is varied by varying a distance therebetween by the oscillating device, whereby an output signal appearing on the detection electrode is detected.
