The present invention relates to a nanospray emitter including an emitter body which includes a fluid inlet, an outlet orifice, and a passage communicating between the fluid inlet and outlet orifice; and an electrically conductive polymer coating on at least a portion of the emitter body. The movable direction determining unit specifies, based on a first operation position on an input area of the input unit, a division part including the first operation position from among plural division parts on the input area. If the number or read errors is excessive, the tape cartridge is deemed unreliable and the tape cartridge is restricted from storing anymore data. The photonic crystal apparatus may also include a driver configured to selectively cause a portion of the photonic crystal to alternate between a distorted state and an undistorted state. A fourth wire is serially connected to a first common node of the first, second, and third wires, and has a first capacitor connected between the first common node and a first sub capacitor and a first sub resistor connected in parallel.
