A sheet processing apparatus, comprising a thickness detecting device, the thickness detecting device including: a plurality of conductive displacement members; a plurality of resonance circuits that are disposed to correspond to the plurality of displacement members, each include a coil facing the corresponding displacement member and a capacitor, and neighboring resonance circuits resonate at different resonance frequencies; and a calculator that calculates a thickness of the sheet based on impedance values of the plurality of resonance circuits and the plurality of displacement members.

A sheet detection device includes: a magnetic sensing element disposed on a sheet guide, wherein the sheet guide brings the magnetic sensing element to move to a first position or a second position; a first magnetic element disposed on a sheet tray corresponding to the first position; a second magnetic element disposed on the sheet tray corresponding to the second position and in spaced with the first magnetic element; a processing element electrically connected with the magnetic sensing element. When the magnetic sensing element outputs a first voltage signal, the processing element determines the sheet guide is located at the first position according to the first voltage signal. When the magnetic sensing element outputs a second voltage signal, the processing element determines the sheet guide is located at the second position according to the second voltage signal. The first voltage signal is different from the second voltage signal.

A lottery ticket vending machine configured to determine if its ticket bursters are improperly separating the lottery tickets received from the ticket drawers of the ticket drawer columns, and to make one or more adjustments and/or alert an operator if its ticket bursters are improperly separating the lottery tickets. In various embodiments, each of the tickets bursters includes a suitable magnetic material sensor configured to sense at least one magnetically sensible material of each lottery ticket received in such ticket burster. In various embodiments, the lottery ticket vending machine includes one or more controllers configured to receive signals from the magnetic material sensor and make such determinations regarding any adjustments and/or alerts, and to cause any such adjustments and/or alerts.

In some embodiments, the instant invention provides an exemplary method for dispensing that at least includes: initiating a movement of a dispensing object along a dispensing passage of a dispensing device; determining, by a displacement sensor, a magnitude of a displacement of the dispensing object along the dispensing passage based on remotely measuring, by the displacement sensor, a characteristic associated with the dispensing object during the movement of the dispensing object along the dispensing passage; generating an indication by the displacement sensor when the magnitude of the displacement is equal to or exceeds a pre-determined distance value; separating, based on the indication, a portion from the dispensing object to form a remaining portion of the dispensing object and a separated portion of the dispensing object; and dispensing the separated portion of the dispensing object from the dispensing device.

A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part has a coil antenna which wirelessly receives the information transmitted from the reader/writer, and a storage part which stores the information on the bill received from the coil antenna.

A steel sheet shape control method includes, (A) setting a target correction shape of the steel sheet at a position of an electromagnet to a curved shape, (B) measuring a steel sheet shape when electromagnetic correction is performed, (C) calculating the steel sheet shape in a nozzle position based on the steel sheet shape, (D) repeating (B) and (C) by resetting the target correction shape to a curved shape having a smaller amount of warp, (E) when the amount of warp of the steel sheet shape at the position of the nozzle is less than the upper limit value, (F) calculating vibration of the steel sheet at the position of the nozzle, and (G) adjusting a control gain of the electromagnet until amplitude of vibration is less than a second upper limit value when the amplitude of the vibration is equal to or more than the second upper limit value.

A sheet conveying device includes a conveying roller, a drive motor, a second detection portion, and a control portion. The control portion includes a first drive control portion, a rotation amount calculation portion, and a second drive control portion. When a front end of a sheet member is detected by the second detection portion, the first drive control portion sets driving of the drive motor in a stopped state before the sheet makes contact with the conveying roller. Rotation amount calculation portion performs a process of calculating a rotation amount of the conveying roller after the sheet member conveyed from upstream in the conveying direction of the sheet member makes contact with the conveying roller. Second drive control portion starts driving of the drive motor at a timing in accordance with the rotation amount of the conveying roller calculated by the rotation amount calculation portion.

An inkjet printer includes a primer applicator to apply primer to media before the media is printed and includes a plurality of eddy current sensors to identify a thickness of the primer on the media. The identified thickness is compared to a range of acceptable primer thicknesses. One end of the range of acceptable thicknesses corresponds to a thickness that is too thin to enable deinking of the printed media and the other end of the range of acceptable thicknesses corresponds to a thickness that is too thick to enable sufficient drying to fix the ink image to the media. In one embodiment, the primer is applied using a printhead that eject drops of primer onto the media.
