In a normal mode that is a mode when a user performs a printing work, a wireless operation unit shifts to a second mode when the wireless operation unit is not operated for a first predetermined time in a first mode. In a maintenance mode when a repairman performs a maintenance work, the wireless operation unit does not shift to the second mode even if the wireless operation unit is not operated for the first predetermined time in the first mode. In addition, in the maintenance mode, if the remaining amount of a battery is equal to or greater than a predetermined amount in the first mode, the wireless operation unit does not shift to the second mode, and if the remaining amount of the battery is less than the predetermined amount, the wireless operation unit shifts to the second mode.

Image forming apparatus

An information processing apparatus includes a nonvolatile memory device in which a program for activating the apparatus is stored, and which has a function of, in a case where an abnormality of management information indicating a correspondence relationship between a logical address and a physical address for data stored in the memory device is detected, performing a process of restoring the an abnormality of the management information is detected at a time of activation of the memory device. In a case where activation of the apparatus based on the program stops part way through, the apparatus is reactivated. Different processes for solving a malfunction in which activation of the apparatus stops part way through are executed based on whether or not an abnormality of the management information is detected in the memory device after the reactivation.

If a user operates a touch panel, a display device notifies the user of a factor of change into a state in which a touch operation has been accepted to restore a state in which a normal touch operation is accepted. The display device monitors coordinate information output from the touch panel, and if it is determined that an operation disabled area located in a first touch panel area excluding the position of an assigned key has entered a state of being designated and a second touch panel area has entered a state of being designated, displays, on a display screen, that the operation disabled area has been designated. The display device thereby notifies the user that operations are not accepted because of a touch operation.

A character area is detected in a reduced layout and a character is detected in the character area, and a character size is compared to a predetermined size readable by a user when characters are printed. A detected character size determined to be smaller than the predetermined size is enlarged. An object adjacent to the detected character in an original document is detected and a content of the objects is determined. A layout position in which a relationship between the enlarged detected characters and the objects is kept is determined according to the determined content and the enlarged characters are arranged. The whole document can be output automatically in an easily viewable state while keeping a meaningful layout relationship between the objects.

In a data storage apparatus having data storage means, if it is judged that a condition of transitioning the data storage apparatus into a power saving state is established, it is controlled so that states of signals to be output by operation control means of controlling an operation of the data storage means to plural signal lines are fixed to a specific signal state, and supply of a reference voltage by reference voltage supply means to the plural signal lines is stopped.

Data storage apparatus and control method of data storage apparatus

In a method for controlling an image forming apparatus capable of reading predetermined information, the image forming apparatus can operate in a first mode in which processing conditions set by a user through a user interface unit of the image forming apparatus can be used or a second mode in which processing conditions based on the predetermined information can be used. Accordingly, operability of the image forming apparatus capable of forming an image by using a document with an information tag can be enhanced.

Image forming apparatus, image forming method and storage medium

An image forming apparatus which is capable of achieving both enhanced userfriendliness and improved energy saving efficiency without being released from a reduced power consumption state by a user who has no will to use the same passing thereby. When a copying machineis in a sleep mode, it is detected whether or not a user has come near to the copying machine. If a contactless ICis present within the range of radio wave signals emitted from an IC tag reader/writer, it is determined that a user has come near because the communication between the contactless ICand the IC tag reader/writecan be carried out. Reading of data from the contactless ICis started, and user authentication is executed based on the data. If, as a result of the user authentication, the user is a licensed user, it is determined whether or not an original document has been set on an automatic feeder. When an original document has been set on the automatic feeder, the copying machineis caused to return to a normal mode as a normal power consumption state from the sleep mode.
