摘要： A wrapping unit for wrapping and forming a predetermined number of stacked coins into a coin-roll is arranged in a lower region of a machine body. A coin storing and feeding unit and sending unit are arranged side by side in a width direction of the machine body above the wrapping unit. Thus, the machine body is downsized in its width direction.In a state where a dispensing box attached to a dispensing box attachment unit is locked, coins are fed from the coin storing and feeding units, and the fed coins are recognized by a dispensing recognition unit, and sent to the dispensing box. If coins for dispensing sent to the dispensing box are normal coins, the dispensing box is unlocked. If an abnormal coin is recognized, a bottom plate of the dispensing box is opened. Coins dropping from the dispensing box are collected in a collection unit.

摘要： An object lens driving apparatus (100) includes a lens holder (4) that holds an object lens (1) facing a recording medium and is so supported that the lens holder (4) is movable toward and away from the surface of the recording medium. A focusing coil (5) is fixed in the interior of the lens holder (4) so that the focusing coil (5) surrounds an optical axis of the object lens (1). By apply current to the focusing coil (5), a driving force is generated, which moves the lens holder (4) toward and away from the surface of the recording medium. By disposing the focusing coil (5) in the interior of the lens holder (4) so that the focusing coil (5) surrounds the optical axis of the object lens (1), a movable part of the object lens driving apparatus (100) can be reduced in size and weight, so that a high sensitivity can be accomplished.

摘要： An optical fiber amplifier surge protective apparatus includes an optical branch unit, an optical delay circuit, a light input hit detecting circuit, a compensation optical signal generating circuit, and an optical multiplexer. The optical branch unit branches an optical signal input from an optical fiber line into a main optical signal on a main optical path and a branch optical signal on a branch optical path. The optical delay circuit delays the main optical signal on the main optical path. The light input hit detecting circuit monitors the level of the branch optical signal on the branch optical path to detect an optical fiber line hit. The compensation optical signal generating circuit generates a compensation optical signal having a wavelength different from that of the optical signal input when the light input hit detecting circuit detects the optical fiber line hit. The optical multiplexer multiplexes the compensation optical signal from the compensation optical signal generating circuit and the delayed main optical signal from the optical delay circuit.
