Abstract: A digital MFP carries out an authentication of an operator by a user ID and a password prior to usage of the digital MFP. The digital MFP requests from the operator an instruction as to whether or not to store the successfully authenticated user ID and password in a flash memory along with a generated abbreviated code. When the operator instructs to store, the successfully authenticated user ID and the password are stored in the flash memory along with the generated abbreviated code. The digital MFP retrieves from the flash memory the user ID and the password that form a pair with the abbreviated code entered by the operator using the operation unit, and acquires authentication success or failure information with respect to the retrieved user ID and the password from an authentication server.

Abstract: An authentication unit of a digital MFP carries out communication with an authentication server and executes an authentication procedure. The authentication unit acquires authentication information from an operator, transmits an authentication request including the authentication information to the authentication server, and receives an authentication result from the authentication server. A determination unit determines whether or not to permit offering of a function called by an operation performed on an operation unit. A flash memory stores a network authentication setting designating necessity or non-necessity of the authentication procedure for each function in a manner that the network authentication setting may be edited. When a function designated in the network authentication setting as a function requiring the authentication procedure is called, the authentication unit executes the authentication procedure.

Abstract: When dot-sequential data indicating a temporal variation in position, speed, or acceleration is stored in a memory in an automated guided vehicle as it is, the capacity of the memory is insufficient and thus needs to be increased. A pattern is mounted in a stacker crane 1; the pattern is drawn by dot-sequential data indicating a temporal variation in acceleration (FIG. 2C), and corresponds to an instruction value provided to an actuator installed in the stacker crane 1. In this case, a curve function corresponding to an approximate expression for the dot-sequential data is derived in a form of a Fourier series having a finite number of terms and using time as an independent variable and the position, speed, or acceleration as a dependent variable. Data identifying the Fourier series, having a finite number of terms, is stored in a memory 5 mounted in the stacker crane 1.

Abstract: An image forming device includes four operation modes: a copy mode, a fax mode, an e-mail mode and a scanner mode. The image forming device can set a processing content of each operation mode for each prescribed setting item. The image forming device includes a favorite keys group to which setting items selected from all setting items of all operation modes can be assigned. Setting items selected from all setting items of a particular operational mode can be assigned to a standby screen keys group included in a standby screen for that operational mode. A setting item not assigned to the standby screen keys group for a particular operational mode is assigned to a menu screen keys group for that operational mode. When detecting an operation performed on a key included in the favorite keys group, the standby screen keys group and the menu screen keys group, the image forming device performs a setting operation for the setting item assigned to the operated key.

Abstract: An image forming device includes a motor, a photoconductive drum, a charging unit, an abrasion tool, a timer, and a controller. The charging unit is provided at a periphery of the photoconductive drum, and charges the photoconductive drum by a corona discharge method. The abrasion tool is provided at the periphery of the photoconductive drum, and abrades the surface of the photoconductive drum while the photoconductive drum is rotating. The timer measures a job interval from when the motor is stopped to end a previous print job until when the motor is driven to start a next print job. The controller executes over a predetermined period of time a pre-rotation process to adjust the photoconductive drum and a peripheral system of the photoconductive drum into an optimum state, and calculates a period when the pre-rotation process is to be executed according to the measured job interval.

Abstract: A communication device and a communication method capable of transmitting data after confirming a destination device in one SMTP communication. A transmitter communication device carries out a communication request to a recipient communication device and SMTP communication is started. The recipient communication device transmits information of a recipient stored in a storage unit to the transmitter communication device under a prescribed procedure. Before receiving the data, the recipient communication device suspends the communication protocol with a communication channel maintained. The transmitter communication device displays the received information of the recipient on a display unit, and suspends the communication protocol with the communication channel maintained. Accordingly, a user can confirm a transmission destination from the display. After confirming the transmission destination, the user instructs to transmit the data.

Abstract: Methods of operating facsimile machines are provided in which a priority table is stored that specifies printing priorities for different types of designated information. A message along with associated image data and first designated information and other messages having other associated image data and other designated information are received. The first designated information and other designated information are then detected. Printing of the associated image data is then controlled based on relative priority of the first designated information with respect to other designated information that have been detected. In one possible implementation, facsimile machines are provided that can include, for example, a receiving unit and control unit. When a first printing job is being executed that includes image data to be printed, the receiving unit receives a communication message having second printing job associated therewith. The second printing job includes other image data.
