    摘要: The control circuit includes: a series circuit of a first triac and a reactor; and a second triac in parallel with this series circuit so as to perform control of activation of a fixing heater. Since the fixing heater has a low resistance when the power switch is first turned on, the first triac is operated to perform phase angle control of current flow, and when the phase angle has become approximately equal to 180.degree., the first triac is stopped, at the same time the second triac starts to be operated. The switching from the first triac to the second triac is made quickly so that it is possible to reduce the power consumption from the reactor.

    摘要: A multi-function printer (MFP) has a main control circuit for setting the operation mode of the apparatus to either a normal operation mode or a power-saving operation mode. There are provided a main power supply circuit and an auxiliary power supply circuit for supplying power to the main control circuit in the normal operation mode and in the power-saving operation mode, respectively. The MFP also has a power detection circuit for detecting a state of power supply from the main power supply circuit to the main control circuit. If a power-save request is followed by a start-up request, when an amount of power detected by the power detection circuit is greater than a predetermined value, the main control circuit stops an operation relating to the power-save request and initiates an operation according to a start-up request.

    摘要: The invention relates to a power supply device and a communication system. The power supply device supplies power to a main device. The communication system is provided with the main device mounting the power supply device therein and an external device connected to the main device. A feature of the invention is to offer a power supply device and a communication system that are capable of being responsive to external signals for returning to a normal operation mode with minimum power consumption in a power-saving operation mode. In the power saving operation mode, a main power supply circuit (60) is turned off and only an auxiliary power supply circuit (50) is operated. In order to detect external signal, the auxiliary power supply circuit (50) supplies power not to an entire interface section (20), but to a ring detection circuit (31), a LAN signal detection circuit (32), a 1284 signal detection circuit (33), a USB signal detection circuit (34), and a panel signal detection circuit (35) that are respectively provided with a minimum functions for detecting external signal.

    摘要: An image forming apparatus includes a main power supply section, an auxiliary power supply section, a plurality of sensors, and a power control section. The sensors are disposed at a plurality of positions. The sensors change output levels thereof upon detection of a user's operation for initiating an image forming process. The power control section switches the apparatus from a normal operation mode to the power-saving operation mode after a predetermined time period during which no image forming process is performed. The power control section detects the respective output levels of the sensors through sequential power supply from the auxiliary power supply section to the sensors. The power control section switches the apparatus to the normal operation mode upon detection of a change in output level of either one of the sensors.

    摘要: A document platen on which a document is placed is movably installed on the main body of a copying machine. A motor for producing a driving force is provided. An input gear to which the driving force is transmitted is located in a fixed position. A planetary gear is positioned such that it engages with and moves around the input gear. An endless gear is connected to the document platen. The endless gear has internal teeth in the form of a closed loop which engages with the planetary gear. When the planetary gear, which engages with both the input gear and the endless gear, moves around the input gear once, one reciprocating movement of the document platen is caused. With this configuration, since there is no need to provide a switching mechanism including clutches and solenoids that is used in a conventional device, the number of components is reduced, and thereby decreasing the manufacturing costs.
