  • Patent number: 9940075
    Abstract: A print inspection apparatus according to the present invention obtains an object for variable printing which is stored in a storage and generates a combined image by combining the obtained object. If the combined image is normally generated, the combined image is set to both of a print image and a collation image. Whereas if the combined image is not normally generated, a different image is set to each of the print image and the collation image. The print inspection apparatus generates a print product by printing the set print image. Then, the print inspection apparatus inspects the print product by comparing image data generated by reading the print product with the set collation image.

  • Patent number: 9936118
    Abstract: An image capture apparatus capable of communicating with an external apparatus via a network has a change unit configured to change an image capture position of image capturing means for capturing an image of an object. In response to a request received from an external apparatus, the image capture apparatus generates a response including a first field in which the operation state of the change unit is described, and sends the generated response to the external apparatus. Here, if the change unit is in initialization, the image capture apparatus generates a response that specifies that the change unit is in initialization using a combination of descriptions in multiple fields, including the first field.

  • Patent number: 9932198
    Abstract: There is provided a sheet processing apparatus with improved visibility of a sheet bundle discharged without post-processing thereto. The CPU circuit receives the conveyed sheet, drives and controls the sheet-returning paddle, the rack part, the rear end regulation part, the alignment plate and the like and forms sheet bundle comprising of a plural number of sheets as received. Further, the CPU circuit drives and controls the alignment plate when discharging the sheet bundle S from the processing tray, the sheet bundle S exceeding the number of sheets which can be post-processed by the stapler. Therefore, the sheet bundle S which includes sheets equal to the allowable number of sheets for post-processing of the sheet processing unit is discharged to the second discharge position which is different from the first discharge position.

  • Patent number: 9933726
    Abstract: A developer container includes a container, provided with an opening and configured to accommodate a developer; a sealing member configured to cover the opening; and an unsealing member configured to unseal the opening by moving the sealing member. The sealing member opposes the container at a central opposing portion positioned in a central side and at an end opposing portion positioned at an end side with respect to a longitudinal direction of the unsealing member. The sealing member and the container are bonded to each other at bonding portion which is at least a part of the central opposing portion. The bonding force at the bonding portion of the central opposing portion is larger than a bonding force between the sealing member and the container at the end opposing portion.

  • Patent number: 9933895
    Abstract: A touch sensor driver circuit drives a capacitive touch sensor to detect the presence of an operation performed with a conductive member and detects a position of the operation. A controller performs processing corresponding to the operation on the touch sensor with the conductive member. In a case where detection of a capacitance greater than or equal to a threshold in an edge area of a sensor area of the capacitive touch sensor and a touch operation in a central area that is the sensor area excluding the edge area occur at the same time, the controller ignores the touch operation.
