Abstract: An image forming device includes a light emission controller that controls emission of a plurality of types of light emission patterns from a plurality of light sources. The light emission controller emits respective light emission patterns corresponding to the operation. When among the plurality of types of light emission patterns, the preceding light emission pattern overlaps with the subsequent light emission pattern, the light emission controller preferentially emits the subsequent light emission pattern having a delay in the light emission start timing. The light emission controller also emits respective first light emission patterns corresponding to the operation, and emits the second light emission pattern expressing the predetermined operation.

Abstract: An image forming device includes a light emission controller which controls emission of a plurality of types of light emission patterns by a plurality of light sources. The light emission controller emits each light emission pattern in response to a plurality of types of operations performed by an operator with respect to an operation portion. The light emission controller causes a light emission start timing of each of the plurality of types of light emission patterns to be different depending on the contents of the operations. The light emission controller emits first light emission patterns in response to operations performed by an operator with respect to the operation portion, emits second light emission patterns in response to a predetermined operation by the image forming device, and causes the first light emission patterns and the second light emission patterns to be different from each other in light emission end timing.

Abstract: A user is enabled to make different selection as to whether or not to include a blank page for each data processing. A storage portion stores setting information indicating whether or not to perform data processing of image data with a blank page excluded for each data processing, and a control portion judges whether or not each data processing is processing performed with a blank page of the image data excluded based on the setting information stored in the storage portion, and executes first data processing which is judged as processing performed with the blank page excluded by excluding the blank page as well as executes second data processing which is judged as processing performed without excluding the blank page concurrently with the first data processing by including the blank page.

Abstract: To effectively assist a user so that the result of aggregate printing matches the intention of the user. A storage portion (16) stores information regarding the attributes of each page. A display (12) displays a preview screen in which icons corresponding to each page included in the manuscript are arranged in page number sequence. An instruction reception portion (17b) receives, from the user, a modification instruction for instructing that the sequence in which the pages are arranged be modified according to a modification to the sequence in which the icons are arranged, the modification being performed by the user in the preview screen. When the modification instruction is received, a modification aggregation determination portion (17d) determines, on the basis of the information regarding the attributes, whether the modification to the sequence of arrangement will result in pages having different attributes being intermixed with the same aggregate page.

Abstract: A user machine is made aware of a need for communication to update a version of a firmware by communication from a service center (a notification that the latest version has been released). After shutting off this communication once, communication is carried out between the official service center and the user machine by the user machine commencing communication with the official service center, the contact information of which is stored, and the service center provides information for updating the new version to the user machine in this communication state.

Abstract: An ASIC (semiconductor device) of an image processing section is provided with an input/output circuit for performing input and output to and from an image processing circuit and a confidential circuit. The input/output circuit performs output to outside of the ASIC at a timing shifted from a timing of output from the confidential circuit, for example, so as to hide the processing of the confidential circuit. With this arrangement, it is possible to hide an algorithm in the confidential circuit. Further, the ASIC is provided with a decryption circuit for decrypting an encrypted program stored in a nonvolatile memory provided separately from the ASIC. The decryption circuit is caused to function as a decryption section upon later-writing into an OTP.
