摘要： A vibration-powered generator (100) has a vibrating element (10) and a coil (40) arranged therearound, and is configured to obtain electromotive force by moving the vibrating element (10) relatively to the coil (40). The vibrating element (10) has a plurality of magnets (20a to 20d) arranged so as to oppose the pole-faces of the same polarity; end supporting portions (12, 13) which support the plurality of magnets from both ends in the direction of arrangement; and a cushioning (16). The cushioning (16) is held between the end supporting portion (12) and the magnet (20c), while being compressed under a stress exceeding the repelling force between the pole-faces of the magnets, so as to keep the magnets (20a to 20d) in a row without leaving a gap in between, overcoming the repelling force.

摘要： A vibration energy generator includes a case, a coil, a permanent magnet, and a shield magnet. The case is elongated in one direction and is made from a nonmagnetic material. The coil surrounds around an outer surface of the case. The permanent magnet reciprocates inside the case along the one direction. The permanent magnet is magnetized with a polarity oriented in the one direction. The shield magnet is disposed in one end portion of the permanent magnet in the one direction. Each of a surface of the one end portion and a surface of the shield magnet facing the surface of the one end portion has the same magnetic polarity. The length of the shield magnet in the one direction is less than the length of the permanent magnet in the one direction.

摘要： An image sensor that is more compact than a contact type image sensor using a rod-lens array and has a depth of field of the same level as a contraction type image sensor using a set of mirrors. The sensor includes an array of a specified pixel-corresponding quantity of micro-lenses arranged for forming an image light reflected from an original document, an array of the specified pixel-corresponding quantity of optical fibers arranged for transmitting an image formed by the micro-lens array as respective optical signals of pixels and an array of light-receiving elements for converting optical signals incident thereon from the optical fiber array into electric signals, wherein the optical fiber array has core-end-faces each having a size smaller than that of an image formed by the micro-lenses and located on the micro-lens-side position from the image forming plane when the original document is placed at a specified base position.
