Abstract: An optical unit includes a movable body including an optical element, a support body swingably supporting the movable body, and a suction mechanism. The optical element reflects light traveling in a first direction to an intersecting second direction. The suction mechanism generates suction force in the movable body between the movable body and the support body, and includes a magnet and a magnetic member. One of the magnet and the magnetic member is in the movable body, while the other is in the support body. The magnet and the magnetic member overlap each other when viewed from a predetermined direction, which is one of the first direction, the second direction, and a third direction. The third direction intersects the first and second directions. When viewed from the predetermined direction, a center of the magnet and a center of the magnetic member are separated from each other.

Abstract: In a press working apparatus, while a servo motor is acting, an upper die is made to come close to a lower die and press working of the first time is conducted on a steel plate. A slider is raised to a movable punch preparation position. A movable punch is protruded from a die face of the upper die by width and locked by a mechanical lock. The upper die is made to come close to the lower die again and the steel plate is pushed with the upper die and at the same time an additional worked portion is pushed and deformed with the movable punch so as to conduct press working of the second time. After the movable punch has been retracted, the slider is raised.

Abstract: In a press working apparatus 10, while a servo motor 24 is acting, an upper die 38 is made to come close to a lower die 52 and press working of the first time is conducted on a steel plate 12. A slider 32 is raised to a movable punch preparation position. A movable punch 90 is protruded from a die face 38a of the upper die 38 by width H and locked by a mechanical lock 94. The upper die 38 is made to come close to the lower die 52 again and the steel plate 12 is pushed with the upper die 38 and at the same time an additional worked portion 12a is pushed and deformed with the movable punch 90 so as to conduct press working of the second time. After the movable punch 90 has been retracted, the slider 32 is raised.
