Abstract: A removable unit has a first unit removably attached to an image forming apparatus, a second unit held by being removably attached to the first unit, and a cover member. The cover member is supported pivotably on the first unit, and can be located selectively either in a first position overlapping, or a second position not overlapping, the attachment/removal path of the second unit. When the cover member pivots from the first position to a third position pivoted through a predetermined angle from the first position toward the second position, from the first unit a reaction force acts on the cover member to restrict its pivoting toward the second position and, when the cover member pivots from the second position to the third position, from the first unit a reaction force acts on the cover member to restrict its pivoting toward the first position.

Abstract: An object of the present invention is to extract image defects from a test image for each type by a simple process. A processor (80) generates a first preprocessed image and a second preprocessed image by executing a main filter process with each of a horizontal direction and a vertical direction of the test image used as a processing direction. The main filter process is a process of converting the pixel value of each pixel of interest sequentially selected from the test image into a converted value obtained by a process of emphasizing the difference between the pixel values of an area of interest and the pixel values of two adjacent areas. The processor (80) extracts, as the image defects, a first singular part that is present in the first preprocessed image and is not common to both images, a second singular part that is present in the second preprocessed image and is not common to both images, and a third singular part that is common to both images.

Abstract: The image processing apparatus includes: an abnormality detection unit configured to detect one or more abnormalities included in a target image and an abnormality exclusion processing unit configured to exclude a specific abnormality from the detected one or more abnormalities. In a case in which a detection area of a certain abnormality among the detected one or more abnormalities and a detection area of another abnormality overlap with each other and a type of the certain abnormality and a type of the another abnormality are different from each other, when brightness information of one of the certain abnormality and the another abnormality satisfies a specific condition, the abnormality exclusion processing unit excludes the one of the certain abnormality and the another abnormality from the detected one or more abnormalities.

Abstract: A detachable unit has a unit housing and a grip portion thereon. The detachable unit is insertable and removal along an insertion/removal trajectory formed inside the body of an image forming apparatus and forming a depression angle as seen from the removal direction. The grip portion has a pressed face facing the upstream side of the unit housing in its removal direction and substantially perpendicular to the insertion/removal trajectory, a first side extending along the lower-end edge of the pressed face, and a second side extending along the upper-end edge of the pressed face. No face extending on the upstream side of the unit housing in the removal direction connects to the first side, and a finger insertion portion into which a finger can be inserted from the side of the first side along the pressed face is formed in the first side.

Abstract: An object of the present invention is to determine the cause of an image defect that occurs in an image forming device with high accuracy while suppressing the amount of calculation at a processor. A processor (80) determines the cause of an image defect on the basis of a test image read from an output sheet of an image forming device (2). The processor (80) generates a plurality of feature images by executing a feature extraction process on the test image. Further, the processor (80) uses each of the plurality of feature images as an input image and determines which of a plurality of cause candidates corresponding to the image defect the input image corresponds to by pattern recognition of the input image.

Abstract: A sheet identification device includes a light irradiation portion. When forming an identification image, the light irradiation portion projects first pattern light (P11) and second pattern light (P12) having different dependences on a fiber direction of a surface of a sheet on an identification region (R1). The identification image is an image of the identification region (R1) of the surface of the sheet on which image formation or image reading is performed, which is used for identifying the fiber direction of the surface of the sheet.

Abstract: A vector generation unit derives a reference feature vector and a document feature vector. A feature quantity extraction unit performs a dimensionality reduction process on the reference feature vector and the document feature vector so as to set a dimensional value as a first feature quantity and derives a cosine similarity between the reference feature vector and the document feature vector as a second feature quantity. A grid division unit classifies documents into first partial regions obtained by dividing a feature quantity space of the first feature quantity, and classifies the documents into second partial regions obtained by dividing a range of the second feature quantity. A training data extraction unit selects, for each combination of a first partial region and a second partial region, a document classified in both the partial regions and sets documents selected with respect to all combinations as training data.
