摘要： A velocity detection apparatus detects a position of a moving object at a first timing and a second timing to detect a velocity of the moving object based on a difference between the first timing and the second timing. The first timing is a timing at which an identifiable mark position of the moving object is detected by a first detector and the second timing is a timing at which the mark position is detected by a second detector. The velocity detection apparatus includes a light source and first and second detectors which detects the mark position based on light obtained by illuminating the moving object using the light source. A vertical projection position of the light source onto a plane which is parallel to a main surface of the first or second detector is located between vertical projection positions of the first and the second detector onto the plane.

摘要： A displacement detection apparatus includes a scale 115 on which marks are disposed, first and second position detection sensors 111 and 112 detecting positions of the marks 110, and a processor 409 performing a calculation processing of an output signal from each of the first and second position detection sensors 111 and 112. The first and second position detection sensors 111 and 112 are disposed at a distance L from each other to be movable relative to the scale 115. The processor 409 calculates a correction value P′ of a mark pitch P of the marks 110 using the distance L, a first time TPK required for K marks of the marks 110 to pass a detection position, and a second time TL required for a specific mark of the marks 110, which are measured at the same time of the first time TPK, to move the distance L.

摘要： An optical encoder includes a light-emitting unit, a scale with a discontinuous part, and a plurality of light-receiving elements arranged in relationship to a pitch of the scale. In the optical encoder, a light beam from the light-emitting unit reflects off the scale, and is received at the light-receiving elements. As a result of the processing of signals from the light-receiving elements, the discontinuous part is detected and the origin detection can be achieved.

摘要： A rotation information record surface of a rotary disk is disposed at an intermediate position between a fixing point of the rotary disk and a rotary shaft and a fixing position of a detection head, so that a stable gap can be obtained with a variation due to thermal expansion being reduced. In order to attain this, the fitting portion of the rotary disk is shaped to have a first fitting portion and a second fitting portion. The first fitting portion is provided for attaining satisfactory coaxiality, and the second fitting portion is adapted to form a clearance into which bonding means such as an adhesive is to be infused. With the above structure, an optimum detection position (i.e. an optimum gap position) would not be varied by a change in the ambient temperature.
