摘要： In an image pick-up apparatus, the image on a visual field over an original copy is focused on an one-dimensional image pick-up device by a lens through a mirror. A prism for taking in the ambient light is disposed at the end portion of the one-dimensional image pick-up device. A sample-hold circuit samples and holds an ambient light signal portion of the image signal Vin and outputs a sample-hold signal Vref. A division circuit performs the operation of division Vin/Vref, using the sample-hold signal Vref. As a result, the image signal Vin will be normalized by the ambient light signal Vref for each scan line (line by line). An amplification circuit amplifies the output Vin/Vref of the division circuit so that the ambient light signal level may become VO and outputs it to an A/D conversion circuit. The image signal quantified by the A/D-conversion circuit is output to an external equipment by an external I/F circuit.

摘要： A label/window position detecting device includes a conveyor, light-emitting elements, a lens, linear image sensors, image processors, and coordinate calculation units. The conveyor conveys a target object having a label/window. The light-emitting elements illuminate the target object which is being conveyed by the conveyor. The lens forms an image of the target object illuminated with the light-emitting elements. The linear image sensors photoelectrically convert image light incident through the lens into image signals. The image processors binarize the image signals obtained from the linear image sensors into monochrome binary image signals, using a predetermined threshold. The coordinate calculation units calculate a label/window position of the target object on the basis of the binary image signals from the image processors, which correspond to a label/window edge portion. A method of detecting a label/window position is also disclosed.

摘要： The present invention enables to scan in a sub scan direction an image on a scan medium placed on a flat plane using a simple configuration of a one-dimensional image sensor at a fixed position in combination with a reflecting mirror. A drive source having a constant rpm is used to rotate the reflecting mirror at an angular velocity changing in a non-linear way. The rotation of the drive source is transmitted to a drive mechanism linked to a four-node link mechanism to rotate the reflecting mirror at an angular velocity changing in a non-linear way, so that the scan position on the scan medium is shifted in the sub scan direction at a constant linear velocity.

摘要： Scanning is performed in a sub scan direction an image on a scan medium placed on a plane with a one-dimensional image sensor at a fixed position via a reflecting mirror rotatable around a fixed axis without causing a scan defect due to a change in the optical path length. An image light generating from an image on a scan medium is deflected by a reflecting mirror so at to form an image at a position of an image sensor via an image formation optical system. The image sensor reads a scan image as a one-dimensional main scan line and the reflecting mirror is rotated so at move a scan position in a sub scan direction. The rotation of this reflecting mirror is interlocked with displacement of the image formation optical system in an optical axis direction, thus enabling to prevent an image formation defect due to a change in the optical path length.
