摘要:
A laser scanner control circuit which is used for an apparatus for scanning onto a photo sensitive material by a laser beam and forming and image thereon is constructed as a monolithic driver IC onto a single chip. A reset circuit is provided for a sample-hold circuit so as to minimize the laser power when the image forming apparatus is in a standby mode. A circuit to detect an abnormality of the laser power is further provided. Due to this, the safety of the laser power control of the sample-hold circuit is improved. The operation of the sample-hold circuit can be started at a time point when the laser emitting operation is stable.

A fixing apparatus includes a heating member; a temperature detecting member for detecting the temperature of the heating member; a power supply controller for controlling the power supply to the heating member so that the temperature detected by the temperature detecting element during a fixing operation is maintained substantially constant at a predetermined fixing temperature; and a temperature selecting device for selecting a fixing temperature in response to both the temperature of the heating member before beginning of the fixing temperature control and a rate of the temperature change of the heating member upon supplying a predetermined amount of power to the heating member or upon turning it off.
摘要:
In an apparatus which cannot detect a size of recording sheet before the recording sheet is fed, the first recording sheet is regarded as having the maximum size and paper feeding is controlled on this basis and the size of the sheet is measured during the conveyance of the recording sheet. For the second or third and subsequent recording sheets, paper feeding control is executed at a paper feeding interval at which a maximum throughput is obtained in accordance with the measured size.
摘要:
An image processing apparatus which is connected to an external instrument via a network stores setting information of the image processing apparatus into a memory and transmits an electronic mail containing the setting information stored in the memory to an electronic mail address destination specified by the user when transmission of the setting information stored in the memory is requested.
摘要:
When a control circuit extracts data of an entity corresponding to a phone number, the control circuit retrieves phone numbers that accord, with respect to lower seven digits of a phone number, with the inputted phone number from among phone numbers included in retrieval data. After the entity having the phone number corresponding to the inputted phone number is extracted, a map including the entity extracted is displayed based on the position information of the entity extracted. Accordingly, even when the area code of the phone number is changed, the map including the corresponding entity can be displayed.
摘要:
An image heating apparatus includes a heater; temperature detector for detecting a temperature of the heater; electric power supply controller for controlling electric power supply to the heater during image heating, so that the temperature detector detects a predetermined set temperature; and a temperature determining device for determining the set temperature on the basis of a change of the temperature detected by the temperature detector when electric power supply to the heater is stopped.
摘要:
An image forming apparatus includes a detecting unit that detects the size of a recording medium and a designating unit that designates the size of a recording medium onto which an image is to be recorded. The comparing unit compares the detected size with the designated size to determine which size is larger and a control unit controls the apparatus to perform operations such that an operation when the detected size is larger than the designated size is different from that when the detected size is smaller than the designated size.
摘要:
A driving support apparatus supports a driver in driving a vehicle on a road by giving instructions. The driving support apparatus includes a recognizing unit that recognizes a current driving lane that is a lane on the road in which the vehicle is currently running; a lane setting unit that sets a driving schedule lane that is a lane in which the vehicle is to be driven; and a guiding unit that determines content of lane guidance based on the driving schedule lane and the current driving lane, and guides the driver to a lane based on the lane guidance when the road is substantially straight.
