Abstract: A magnetic sensor device may include a magnetic sensor element structured to detect a magnetic property of a medium. The magnetic sensor element may include a sensor core having a body part and one or a plurality of protruded part(s) which is protruded from the body part, an exciting coil which is wound around the sensor core, and a detection coil which is wound around the sensor core. The body part and the protruded part of the sensor core forms an open magnetic path, and a stepped part is formed on a side face of at least one piece of the protruded part.

Abstract: An optical unit with a shake correcting function may include a fixed body, a movable body holding an optical element, a swing support point which supports the movable body so that the movable body is capable of swinging, a spring member formed in a plate shape for urging the movable body toward the swing support point, a shake correction drive mechanism structured to swing the movable body with the swing support point as a swing center, a first stopper part which is protruded in a direction perpendicular to the optical axis direction on a front side in the optical axis direction of the movable body with respect to the spring member for determining a moving range of the movable body, and a second stopper part which is structured to face the first stopper part in the optical axis direction through the spring member on the rear side in the optical axis direction of the fixed body with respect to the spring member for determining a moving range of the movable body in the optical axis direction by restricting move

Abstract: A control unit for controlling a card reader. The control unit includes an authentication management unit for transmitting/receiving information to/from a host and each of a first encryption magnetic head device and a second encryption magnetic head device to mutually authenticate each other. The authentication management unit includes (1) a commanding means for commanding one of the first encryption magnetic head device and the second encryption magnetic head device to create lower-level information for authentication, according to a request on authentication from the host, (2) a sharing means for transmitting the lower-level information for authentication received from the above-mentioned one device to the other device for the purpose of sharing it and (3) a transmission means for transmitting the lower-level information for authentication, having been shared in all of the first encryption magnetic head device and the second encryption magnetic head device, to the host.

Abstract: A bobbin with a terminal may include a winding part having a tube shape around which a conducting wire is wound, a terminal block which is formed on one end side in an axial direction of the winding part, and a plurality of terminals which is protruded from the terminal block in a direction substantially perpendicular to the axial direction of the winding part. A tip end of the terminal is formed with an inclined face which is inclined with respect to the axial direction of the winding part, and the inclined face is inclined so that the conducting wire abutted with the tip end of the terminal is slid down only toward the winding part when the conducting wire is to be wound around the winding part. The bobbin with a terminal may be utilized in a motor provided with a drive coil which is structured of the conducting wire.
