An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor.

An image reading apparatus includes: a contact glass setting a manuscript thereon; an image sensor extending in a first direction and having a reading surface which faces the contact glass for reading an image from the manuscript on the contact glass; a rail member extending inside the apparatus main body in a second direction perpendicular to the first direction; a carriage having a sensor container to contain the image sensor, a taper end portion formed in an end portion in the first direction to become smaller in height toward the end side, and an opening formed in the bottom of the sensor container on the taper end portion side; a biased portion adjacent to the reading surface of the image sensor in the second direction; and a biasing member biasing the image sensor toward the contact glass via the biased portion.

One embodiment relates to a method of acquiring three-dimensional structure of an object using a flatbed scanner. The object is placed (302) with a surface to be scanned facing down on a scanner platen. At least three images are obtained under differing lighting directions (for example, 304, 306, 312, 314). The images are processed (316) to generate the three-dimensional structure. Other features and embodiments are also disclosed.
摘要:
Pour réduire le nombre de pièces utilisées pour la réalisation d'un tendeur (200) de courroie dans un scanner on intègre un bras (201) flexible dans le moule de la coque du scanner. Le bras flexible sert ainsi de support à une poulie (106) sur laquelle est engagée la courroie (104) à tendre, et l'élasticité du bras flexible assure la tension de la courroie. Le bras flexible a une géométrie ce qui lui permet d'être rigide dans les plans non horizontaux et améliore la tension du ressort. Dans une variante, un ressort (300) en épingle coopère avec le bras flexible pour la tension du ressort. Ce ressort est maintenu en place via des éléments (206, 207) eux aussi moulés dans la coque du scanner.
摘要:
Die Erfindung betrifft eine Anordnung zum Stützen von flexiblen Bahnen, Bändern, Kabeln oder Leitungen (28), mit einem langgestreckten Stützkörper (30), dessen beide Enden relativ zueinander bewegbar sind, wobei der Stützkörper (30) zwischen seinen beiden Enden einen Bogen beschreibt. Erfindungsgemäß wird als Stützkörper ein Flachband (30) mit einer vorgeformten Querwölbung verwendet. Des Weiteren betrifft die Erfindung eine Vorrichtung zum Auslesen von Informationen, in der eine derartige Anordnung als Kabelführung eingesetzt ist.
摘要:
An image reader is composed of: a read unit 2 provided with a contact member 21 which abuts an original bed 11 of a flat bed unit 1; and a pressing element 30 for causing the read unit 2 and the original bed 11 to press against each other. Also, the image reader is composed of: an apparatus body 50 including a read unit 102 and an original bed 51; and an original cover 42 including a light source 43 and a diffusion plate 45 and attached to the apparatus body 50 in such a manner as to be freely opened and closed. The distance between a translucent original 41 placed on the original bed 51 and the light source 43 is variable according to the thickness of the translucent original 41. Further, in the image reader, a cumulative difference between the movement of the optical unit 102 and the movement of a light source unit 44 is previously read; and, at the time of start of scanning for read, the relative position of the optical unit 102 and the light source unit 44 is shifted in reverse in relation to the direction of the cumulative difference.

A scanning apparatus (100) including a movable scan carriage (220) and separate fixed object focal planes (106, 210) for scanning transmissive and reflective original documents. A dark slide (1714) provides protection against flare during scanning, and can be closed to provide for dark current calibration as well as to seal the system (1710) from dust when not in use.
