An imaging device and a portable information terminal device of the present invention include: a blade driving unit () made up of a base plate () having an opening portion () serving as an optical path, an infrared light cut filter blade () movably supported by the base plate between a receded position displaced from the opening portion and a position facing the opening portion, and a first electromagnetic driving source () that drives the infrared light cut filter blade (); a lens optical system () arranged on the optical path passing through the opening portion; an imaging element () that images an object through the lens optical system; and a control unit () that drives and controls the blade driving unit () and the imaging element (). The control unit drives and controls the first electromagnetic driving source () so as to move the infrared light cut filter blade () to the receded position when using an infrared light. In this way, the infrared light cut filter blade is provided so as to be able to recede from the opening portion, so that the normal imaging can be performed, and at the same time, the biometric information (blood vessel image) for authentication can be also imaged.

Imaging device and portable information terminal device

A transparent plate is fixed to the body of a mobile phone with a camera in order to cover an aperture for photography. A solid-state image sensor () is placed on the image plane of a photographing optical system. Between a base plate having an aperture for regulating the optical path of photographing light and a cover plate having an aperture, a blade chamber for housing a shutter blade is provided, and an actuator for driving the shutter blade is fixed to the outer surface of the blade chamber. The base plate and the cover plate are arranged in the body so that the aperture is located between the transparent plate and the photographing optical system.

Portable information terminal with camera

A stepper motor in which the end portions of each of a pair of conductors are connected to their corresponding terminal processing units arranged in one array in the circumferential direction outside of stator units. The terminal processing units are integral with bobbins on which the conductor is wound in the stepper motor.

Stepper motor with input connector array

A magnetoresistance element is arranged in a plane parallel to the end face of a PG yoke and is situated on the outer side of a circle described by revolution of the PG yoke end face and in close proximity to the end face to detect a characteristic flux component emitted from the PG yoke end face. The magnetoresistance element is disposed in such a manner that an acute angle is formed between the direction of a current flowing in the element and a normal line extending from the axis of rotation of a recording medium. A flux component hardly influenced by the area of the PG yoke end face is thus detected.
