The database includes, for multiple different first types of objects, a first output data which are output data of an optical system acquired beforehand for each of the first objects in a case in which a surface of one side of the first object is set as the detection surface; and a second output data which are output data of the optical detection system acquired beforehand for each of the first objects in a case in which a surface of an other side opposite to the one side of the first object is set as the detection surface. The processing apparatus matches measurement data with the database, the measurement data being the output data of the optical detection system which is acquired with respect to a second object, and determines a type of the second object. | 01-15-2015 |
20150062582 | SENSOR APPARATUS AND IMAGE FORMING APPARATUS INCORPORATING SAME - A sensor apparatus includes an irradiation system with a light source configured to emit linearly polarized light of a first polarization direction onto a sheet-like object, in a direction oblique to a direction orthogonal to a surface of the object, a first photodetector arranged on an optical path of light that is emitted from the irradiation system and then is reflected at the object by regular reflection, a first optical element, arranged on an optical path of light reflected by diffuse reflection from an incidence plane of the object, configured to transmit linearly polarized light of a second polarization direction that is orthogonal to the first polarization direction, a second photodetector configured to receive light that has passed through the first optical element, and a detection unit configured to detect at least one of basis weight and thickness of the object. | 03-05-2015 |
20150071658 | SENSOR DRIVE AND IMAGE FORMING APPARATUS INCORPORATING SAME - A sensor device and an image forming apparatus incorporating the sensor device are provided. The sensor device includes a light source, a photo-detection system configured to receive light emitted from the light source and reflected at a sheet-like object, a housing accommodating the light source and the photo-detection system, the housing having a slit into which the object is inserted, and a holding member configured to hold the object such that relative positions of a surface of the object inserted into the slit and the photo-detection system are fixed. The image forming apparatus includes an image forming unit configured to form an image on a recording medium, the sensor device, and an adjustment unit configured to adjust a condition for image formation, based on an output from the sensor device. | 03-12-2015 |
20150261163 | OPTICAL SENSOR AND IMAGE FORMING APPARATUS - An optical sensor includes a light source; and an optical detector detecting intensity of light that is reflected by a recording medium, the light from the light source and irradiated onto the recording medium. Further, when an incident angle of the light incident the recording medium from the light source relative to a normal line of the recording medium is given as θ | 09-17-2015 |
