摘要： There is disclosed an object to allow a cleaning member to contact a rotary magnetic head, forcibly scrape off foreign matters, fulfill an original read/write performance or characteristic, and to enhance reliability. A head cleaner is provided with a motor for operating by a power independently of the rotation of a rotary head drum, a cleaning member forcibly driven by the motor to rotate, an arm having one end for supporting the motor and a middle portion rotatably supported on an apparatus base by an arm support pin, a spring having one end connected to the other end side of the arm and the other end fixed to the apparatus base, and a follower roller on the other end of the arm. The follower roller is in a position relation in which when a loading cam wheel rotates and a cam on the side face of the loading cam wheel pushes up the follower roller, the follower roller moves apart from the center of the loading cam wheel.

摘要： An original placement table is provided, on which an original sheet is placed. An original scanning device causes a light beam to scan the original sheet placed on the original placement table. A light receiving device receives a light beam which has been reflected by the original sheet placed on the original placement table after being emitted by the original scanning device. An original edge determining device monitors light intensity of the light beam received by the light receiving device. The original edge determining device determines that the light beam currently being received by the light receiving device is the light beam reflected by an edge of the original sheet placed on the original placement table when a significant variation is detected in the light intensity either for the first time or for the last time in one scanning operation of the original scanning device.

摘要： The improved photodiode array has a structure that has pn-junctions arranged in a row on a semiconductor substrate 1 having an oxide film 2. The photodiode array has such a surface pattern that n-type impurity diffused layers 3 and p-type impurity diffused layers 4 are arranged in a generally concentric manner or with layers of one diffusion type alternating with layers of the other diffusion type. The improved process of fabrication comprises joining the oxide film 2 on the semiconductor substrate 1 to an n-type semiconductor layer 3 and then diffusing a p-type impurity within the n-type semiconductor layer 3 to form pn-junctions, thereby yielding a photodiode array. Thereby, it is provided a photodiode array that has such a simple structure that not only is the yield of device fabrication improved but also the cost of the final product is reduced.

摘要： An objective is to achieve a positional change measurement device which measures positional change of a dynamic measured surface by using speckle patterns while easily reducing influence of fluctuations in a measurement environment temperature. Provided is a positional change measurement device including: a light source; an illuminating optical system configured to guide light from the light source to a measured surface; an imaging optical system; an image pickup device configured to acquire a speckle pattern by receiving reflection light from the measured surface via the imaging optical system; and detected-length compensation means for compensating for fluctuations in a detected length caused by temperature fluctuations. Positional change of the measured surface is measured based on a result of cross-correlation computation performed on multiple speckle patterns acquired at predetermined time intervals.
