An image forming apparatus includes an image forming portion that forms an image on a recording medium, a display portion that displays information regarding image forming with the image forming portion, a memory storing instructions, and a controller, which executes the instructions, that detects a position of an instruction portion in contact with a surface of the display portion and generate first input information indicating the detected position of the instruction portion, and detects a position of the instruction portion at a location a predetermined distance away from the surface in a direction orthogonal to the surface and generate second input information indicating the detected position, and transitions the image forming apparatus into a first input mode for generating the first input information without generating the second input information and transition the image into a second input mode for generating the second input information without generating the first input information.

Image forming apparatus with touch and touchless input portion

An image forming system comprising: an image forming apparatus capable of transitioning between a standby mode and a sleep mode; and a wireless operation device capable of wireless communication with the image forming apparatus, the wireless operation device including: a display; a battery configured to perform power supply to the display; and a controller configured to control the power supply from the battery to the display, wherein, in response to transition of the image forming apparatus from the standby mode to the sleep mode with a predetermined amount of power being supplied from the battery to the display, the controller makes a supply amount of power from the battery to the display less than the predetermined amount.

Image forming system and wireless operation device

In an image forming apparatus, in a case that a connected numerical key unit is a dedicated numerical key unit including a numerical key portion for executing, as predetermined processing, numerical value input processing for inputting information on a numerical value and including an operation key portion and a setting key portion for executing, as predetermined processing, another input processing for inputting information on an operation of the image forming apparatus other than the numerical value input processing (step S; YES), a controller executes the predetermined processing in a case that either of the respective key portions is operated (step S). On the other hand, in a case that the connected numerical key unit is a general-purpose numerical key unit different from the dedicated numerical key unit (step S; NO), the controller executes the predetermined processing only in a case that the numerical key portion is operated (step S).

Image forming apparatus controlling input from a first input device or a second input device based on which is connected to the image forming apparatus

An image forming apparatus includes an information storing unit, an information acquiring unit and a control unit. On the basis of association between pieces of identification information stored in the storing unit and pieces of user information, the control unit authenticates the use of the image forming apparatus by a user corresponding to an associated piece of identification information. Upon acquisition by the acquiring unit, of a piece of identification information which is not stored in the storing unit, the controller unit causes a display portion to display display regions corresponding to pieces of user information so as to be selectable to cause the storing unit to store piece of identification information and a corresponding piece of user information in association with each other.

Disclosed is an image forming apparatus that includes: a detecting unit configured to detect a user approaching the image forming apparatus; a communication unit configured to be capable of receiving the job from a mobile terminal via short-range wireless communication; and a controlling unit that controls a power supply such that electric power is supplied from the power supply to a first device and a second device in response to detection of the user by the detecting unit, and controls the power supply such that in response to designation of a job from the mobile terminal via the short-range wireless communication, the power supply continues supply of the electric power to the first device that is used for executing the designated job and the power supply stops supply of the electric power to the second device that is not used for executing the designated job.

Image forming apparatus capable of performing wireless communication with mobile terminal

An image forming apparatus includes an image forming portion for forming an image on a sheet; a display portion that displays a predetermined display for accepting, through touch operation, start of a predetermined operation of the apparatus; a position detector that detects a touched position when the touch operation is carried out; and a controller that controls the predetermined operation on the basis of the touched position detected by the position detecting portion. The controller executes the predetermined operation when the predetermined display is made on the display portion, and the position detecting portion detects the touched position, and the controller does not execute the predetermined operation when the predetermined display is not made on the display portion due to display failure, and the position detecting portion detects the touched position.

A method of determining a power transmission device to be set as a master device such that wasteful communication is not caused. In a wireless power feeding system, a power transmission device that transmits electric power to a power reception device forms a group with other power transmission devices. The power transmission device performs communication with the power reception device or the other power transmission devices using a wireless transmission section and a wireless reception section, and exchanges information with the other power transmission devices. The power transmission device receives a setting for determining a power transmission device to be set as a master device out of the self device and the other power transmission devices, with which information has been exchanged. If the received setting is for setting the self device as the master device, the self device is set as the master device.

An image processing apparatus acquires user information and changes a default setting value for at least one of a plurality of processes that are defined in a process definition file. The changed default setting value is displayed on a setting screen. The image processing apparatus changes the default setting value based on the frequency with which a setting value has been changed by a user that corresponds to the user information in processing in accordance with the process definition file.

A connection device for connecting between a multifunction peripheral and USB devices. A hub unit is disconnectably connected to the multifunction peripheral via a first interface for enabling power supply from the multifunction peripheral to the hub unit. The hub unit is also disconnectably connected to the USB devices via a second interface for enabling power supply from the hub unit to the USB devices. A dedicated power supply connector is connected to a power supply section of the multifunction peripheral via wiring for enabling power supply from the multifunction peripheral to the hub unit. A hub circuit relays data between the multifunction peripheral and one of the USB host connectors of the hub unit. Power from the first interface to the hub circuit is supplied through a first power path, and power from the multifunction peripheral to the USB devices is supplied through a second power path.

Connection device for connecting between electrical devices

When a printing process on a first apparatus is interrupted due to an error and the printing process is resumed by a second apparatus, it is determined whether a predetermined function (for example, stapling) is selected for the printing process according to the printing mode. If the predetermined function is selected for the printing process, the second printing apparatus prints the number of copies including the copy interrupted in the first machine according to the print setting. If the predetermined function is not selected for the printing process, the second printing apparatus prints the number of copies excluding the interrupted copy and the unprinted pages in the interrupted copy according to the print setting.
