  • Patent number: 11693606
    Abstract: 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 S12; YES), a controller executes the predetermined processing in a case that either of the respective key portions is operated (step S13). 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 S1; NO), the controller executes the predetermined processing only in a case that the numerical key portion is operated (step S14).

  • Patent number: 11611684
    Abstract: 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.

  • Patent number: 10211675
    Abstract: 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.
