The present invention relates to an image input device including a substrate, a light sensor, a light emitter, and a light guide. The light sensor, the light emitter, and the light guide are provided on the substrate. The light emitted from the light emitter is guided to a position above the light sensor by the light guide.

Image input device that generates an image of an object

The invention provides a fingerprint input apparatus capable of more stably providing an image 'of a higher definition than in prior technologies. The fingerprint input apparatus includes an LED chipand a solid image pickup device substrate 1 adapted to irradiate a fingerof a fingerprint inputting person with & light from the LEDand bearing a solid image pickup device for receiving light scattered in the interior of the finger, and reads the fingerprint of the fingerbased on a light reception signal of the solid image pickup device. The solid image pickup device is constituted of a one-dimensional or two-dimensional image pickup device formed on a rectangular solid image pickup device substrate. A rectangular protective memberis adhered to a side, to be contacted by the finger, of the solid image pickup device substrate. In the protective member, among four sides L, L, Wand Wconstituting a rectangular external shape, two longer sides Land Land a shorter side W1 have the same shape as the external, shape of the solid image pickup device substrate

Image reading using irradiated light

To provide a package for an optical semiconductor having a light-emitting device and a light-receiving device in one package, in which a groove is provided between the light-emitting device and the light-receiving device to thereby avoid rays of light from the light-emitting device to directly enter the light-receiving device.

Package for optical semiconductor

For providing a compact illuminating device capable of uniform illumination with a high intensity, there is provided a light conductive member including a light entrance face provided in a part of a lateral face of a rod-shaped translucent member, an area provided on a side opposed to the light entrance face, for reflecting and/or diffusing the entered light in the longitudinal direction of the translucent member, and an exit face provided in at least a part of a lateral face other than those on which the area and the light entrance face are provided, for emitting at least a part of thus reflected and/or diffused light beam.

A sensor unit and LEDs are arranged on a sensor board. A light guide is placed above the resultant structure with be parallel to the sensor. The two end portions of the light guide are bent downward at right angles, and the bent end portions serve as incident portions on which light beams from the LEDs are incident. Light entering the light guide emerges from an exit portion to be irradiated on an original. The light reflected by the original is read by the sensor. The direction in which the reflected light is incident on the sensor is parallel with the direction in which the light from each LED is incident on the incident portion. With this structure, in the image sensor, electrical connection between the LEDs, the sensor unit, and an external system is facilitated.

Image reading apparatus

A data recording/reproducing apparatus in which plural disc-shaped recording/reproducing means are run in parallel. The apparatus is designed for avoiding the risk of the write/readout unit being changed in size to lower the transfer rate to raise the cost brought about by changing the number of the disc-shaped recording/reproducing means. A disc array unit,accesses video data of 163840 bytes equal to 40 times as many as 4096 bytes and audio data of 8192 bytes equal to twice as many as 4096 bytes to a data driving unit,D made up of seven HDDs with a size of, for example, 3584 bytes. An accessing control unit,controls data accessing to the disc array unit,. A data adjustment unit,appends a volume of nonsensical data (padding data) equal to a multiple of 3584 bytes at the time of recording, while taking out data excluding the padding data during reproduction in terms of 4096 bytes as a unit.

Method and apparatus for recording and/or reproducing data wherein padding data may be added during recording and removed during reproduction

For preventing occurrence of interference fringes derived from interference of light rays on a contact plane between a contact glass and a cover glass, and thus homogenizing an output wave that may otherwise undergo the adverse effect of interference fringes, a close-contact type image sensor includes a contact glass arranged to come into contact with a read surface of an original, a light source for irradiating light to the read surface, an image forming lens for converging light reflected from the read surface, an image sensor part for reading an image of the original formed on an image plane of the image forming lens, and a cover glass for fixing the light source and the image forming lens at respective predetermined positions in a housing, wherein an air layer is present between the contact glass and the cover glass.
