摘要： A shake correction device may include a housing unit; a movable body; a fixed body; a swing support mechanism; a shake correction drive mechanism; and a posture return mechanism. The shake correction drive mechanism may include a magnet and a coil, the coil being configured to apply an electromagnetic force to the movable body. The posture return mechanism may include the magnet and a magnetic member, the magnetic member configured to urge the movable body toward the reference posture. The magnetic member may include a convex surface protruding, and the other body may include a radial positioning unit to press the convex surface of the magnetic member against the radial positioning unit by the attraction force to position the magnetic member in a direction orthogonal to the axial line. The radial positioning unit may include a concave surface with which the convex surface is contacted.

摘要： A card insertion unit is provided, which prevents the mixture of lights in different colors even with light sources to emit lights in different colors at the periphery of a card insertion slot. A card insertion unit, having a card insertion slot through which a card is inserted, includes: a plurality of light sources provided to surround the card insertion slot, when viewed in an insertion direction of the card, with a light emitting unit facing in a direction opposite to the insertion direction so as to each emit lights in multiple colors; a translucent cover member that is provided with the card insertion slot and is overlapped with the light sources in the direction opposite to the insertion direction; and a reflective member provided between the light sources and the card insertion slot to reflect light that is to travel from the light sources toward the card insertion slot.

摘要： In a unit with shake correction function, a driving magnet and a driving coil which constitute a rolling drive mechanism are arranged on an outer side of a radial direction with respect to a disposition space for an optical module that is provided in a movable body. Therefore, since there is no need to arrange the disposition space and the rolling drive mechanism to be deviated from each other in an optical axis direction, it is possible to make the unit with shake correction function thin in the optical axis direction. Further, in the rolling drive mechanism, since the driving magnet and the driving coil face each other in the optical axis direction, a magnetic field of the rolling drive mechanism does not easily enter the disposition space for the optical module. Consequently, magnetic interference between the movable body and the rolling drive mechanism can be suppressed.

摘要： A card reader for processing an inserted magnetic card may be equipped with a front sensor arranged in the vicinity of an insertion opening for a magnetic card to detect the insertion of the magnetic card, a rear sensor for detecting the magnetic card when the magnetic card is fully inserted, a magnetic field generating unit for generating a magnetic field in the vicinity of the insertion opening for a magnetic card, and a control unit for controlling a magnetic field to be generated by said magnetic field generating unit at a first strength or at a second strength weaker than the first strength. The control unit may control the strength of the magnetic field to be generated by the magnetic field generating unit at the second strength while the first time period elapses after the rear sensor has detected the magnetic card and then has stopped sensing it.
