    摘要： A drive unit in accordance with the present invention is provided with a magnetic field generating member generating a magnetic field, a magnetic field detecting device constituted by first, second and third magnetic field detecting elements detecting the magnetic field, and a piezoelectric actuator moving the magnetic field generating member. When executing a relative positioning between the magnetic field generating member and the magnetic field detecting device on the basis of a detection result by the magnetic field detecting device, a first positioning is executed on the basis of the detection result of the first and second magnetic field detecting elements in a predetermined region, and a second positioning is executed on the basis of the detection result of the third magnetic field detecting element at a predetermined point apart from the predetermined region, within a movable range in which the magnetic field generating member moves. In accordance with the structure, it is possible to position the movable body at a high precision, even in the case that a plurality of position detecting points of the movable body of the drive unit exist at a wide interval.

    摘要： A plurality of linear actuators (10, 20, 30) connected in sequence orthogonally to one another constitute rectilinear movement means having a plurality of degrees of freedom in rectilinear movement. Further, a rotary actuator (40) has one end connected to the linear actuator (30) on the last stage and the other end connected to a base side of an end effector (50) and works as attitude change means for changing an attitude of the end effector (50). When the rotary actuator (40) changes the attitude of the end effector (50), the linear actuators (10, 20, 30) are driven to offset a positional movement of an object occurring with the attitude change. This makes it possible to offset the positional movement of the object occurring with the rotary operation with a relatively simple constitution, and further the actuators can be constituted of the minimum elements, thereby providing a downsized micromanipulator.

    摘要： A cap with a display device includes a display element suspended in a position below a visor of the cap and in front of the forehead of a wearer and above the eyes of the wearer so as to allow a display surface of the display element to be directed ahead of the wearer, and a concave mirror suspended in a position below the visor and ahead of the display element from the wearer so as to allow a reflective surface of the concave mirror to be directed to the eyes of the wearer. The cap with a display device enables the wearer to observe an enlarged virtual image derived from an image displayed on the display element.

    摘要： A camera having an auto zoom function includes: a taking lens for photographing an object; a distance measuring device for measuring a distance to the object; a magnification setting device for setting a photographing magnification for the object; and a focal length calculator for calculating a focal length of the taking lens to obtain the photographing magnification set with respect to the distance to the object. Auto zoom operation is carried out by automatic movement of the taking lens so that the focal length of the taking lens may be equal to the calculated focal length.
