Abstract: A display device includes a panel, a power controller, and a controller. The panel includes a first region, to which power is supplied in a partial-screen mode including displaying an image only on a partial screen of the panel, and in a full-screen mode including displaying the image on an entire screen of the panel, and a second region to which the power is supplied, only in the full-screen mode. The power controller causes the panel to display the image, by supplying the power to the panel. The controller controls the panel and the power controller, to cause the first region to display the image, in the partial-screen mode, and acquires input information from the first region. In the full-screen mode, the controller causes the first region and the second region to display the image, and acquires the input information from the first region and the second region.

Abstract: An image information transmission method includes receiving, determining, requesting, causing, and cancelling. In the receiving, an instruction to transmit image information to an image forming apparatus is received from an information communication terminal. In the determining, information relating to a location of an operator of the information communication terminal that is stored in storage is referenced upon execution of the receiving. In the determining, whether or not the operator is in a site where the image forming apparatus is installed. In the requesting, when the operator is not in the site where the image forming apparatus is installed, the information communication terminal requests the operator to determine whether to transmit the image information to the image forming apparatus.

Abstract: In an image forming apparatus, a humidity sensor measures a humidity. A fuser fixes a toner image on a paper sheet. A first sheet detecting sensor is arranged in an upstream side of the fuser in a sheet transportation path, and detects passing timings of front and rear ends of the paper sheet. A second sheet detecting sensor is arranged in a downstream side of the fuser in a sheet transportation path, and detects passing timings of front and rear ends of the paper sheet. An anomaly detecting unit detects anomaly of the humidity sensor on the basis of (a) a ratio or difference between a first sheet length based on the passing timings detected by the first sheet detecting sensor and a second sheet length based on the passing timings detected by the second sheet detecting sensor and (b) a measurement value of the humidity sensor.

Abstract: Provided is an image forming apparatus capable of detecting the ON/OFF state of each of two interlock switches connected in series to a power line, and detecting the opening/closure of each of two covers. The first and second interlock switches are set on/off according to the opening/closure of the first and second covers respectively. The first interlock switch is connected to a supply voltage when the first interlock switch is on, and is connected to a detection voltage being lower and on which the load does not operate when the first interlock switch is off. A control part detects the opening/closure of the first cover and the second cover based on a voltage on the power line between the first interlock switch and the second interlock switch and a voltage on the power line between the second interlock switch and the load.

Abstract: An electronic device includes a power supply, a current measuring unit, a converter, a plurality of devices, and a control unit. The current measuring unit measures a current value of current that is output from the power supply. The voltage and the current from the power supply are input into the converter, and the converter converts the input voltage into voltage of a different voltage value, and outputs the voltage thus converted and the current. The control unit controls the converter to output voltage of a voltage value corresponding to a minimum current value measured by the current measuring unit, in which the voltage is voltage of a voltage value between a maximum value of lower limit voltage and a minimum value of upper limit voltage within an operating voltage range of one or a plurality of devices that operate in the energy saving mode.

Abstract: An image forming apparatus includes: an image forming section; a discharger for discharging and guiding the copying paper to an outlet; and a controlling section for operating the image forming section, based on an image forming instruction from an operation section. A data fetching section fetches first image data on a plurality of pages and second image data on a plurality of pages. The operation section accepts, as the image forming instruction, a sheaf-unit sorting instruction which includes a predetermined number of copies of each of the first image data and second image data and sorting of the copies. The controlling section, based on the sheaf-unit sorting instruction executes, for the predetermined number of copies, an operation of guiding the first and second sheafs of copying paper, in sequence, to the outlet so that the first sheaf and second sheafs of copying paper are piled in order.
