摘要： A size-reduced image reading apparatus for optically reading an image drawn on the document surface. The size reduction is achieved this way. Two light sources are so mounted over the document surface at a specific angle formed with the document surface that they are a certain distance away from each other and bilaterally symmetrical. These light sources are surface light emitters made by forming a light-emitting layer on a transparent substrate. And a fiber lens formed of a plurality of bundles of optical fibers is mounted in the gap between the two surface light emitters. Even if the surface light emitter is brought close to the reading position, a uniform illuminance intensity can be obtained at this reading position. Furthermore, if a fiber lens with a small diameter is used in place of the rod lens, the conjugate length can be shortened.

摘要： A magnetic tape recording and/or reproducing apparatus having two electric motors, one of which is a capstan driving motor and the other is a reel driving motor. A tape drive capstan is directly driven by the said capstan driving motor without any belts, and transports magnetic tape at a constant velocity by coaction with a pinch roller during recording or reproducing of the magnetic tape. The apparatus has two tape winding reels, and the magnetic tape is wound up by either of the two tape winding reels according to the direction in which the magnetic tape is required to be transported. Each of the two tape winding reels is respectively rotated through idle wheels by the reel driving motor, which is separate from the two tape winding reels, without any slippage at the tape winding reels during recording or reproducing. The idle wheels can engage with both an output shaft of the reel driving motor and one or the other of the two tape winding reels to transmit the rotation of the output shaft of the reel driving motor to one or the other of the two tape winding reels during recording, reproducing and fast feed in both the forward and backward direction of the magnetic tape.

摘要： An image reader for reading an image drawn on a paper or a sheet-like recording medium, an image processor provided with the image reader, such as a copying machine, a scanner and the like, and a fiber lens to be applied to those devices. The image processor has to be large in the whole size of device to read both sides of an original. Therefore, the image processor of the present invention comprises an image reader (10a) on the upper side of transport path and an image reader (10b) on the lower side of that respectively. In order to downsize the device, it is necessary to shorten the diameter of optical fiber (140) of the fiber lens (14) installed in the imager reader as light receiving means. In this case, the optical fiber (140) is provided with a light-absorbing layer 8 (143) around of the optical fiber (140) in order to restrain the crosstalk and the flare phenomenon. The illuminance of light source means (15) installed in the image reader gets smaller as the device is downsized. In case where the illuminance is small, the image quality is deteriorated by the floating of the original. Accordingly, the image reader should be provided with the light source means so as to uniform the illuminance over a specific width of the main and sub scanning directions. Therefore, it is possible to avoid the deterioration of the image quality.
