摘要： When preliminary scanning is started, a reference signal is generated from a reference position sensor and a moving amount of the scanner is measured by counting. Change in intensity of the reflected light from a platen is detected by a first sensor according to movement of the scanner. When the detected intensity attains reference intensity, the moving amount of the scanner is stored. When the detected intensity attains again the reference intensity after it has been lower than the reference intensity, the stored moving amount of the scanner is updated. The time in which the detected intensity attains the reference intensity is measured and when it attains a predetermined time, absence of the original is determined and the scanner stops and returns. The size of the original is determined based on the moving amount of the scanner stored at that time.

摘要： A scanner starts to move for preliminary scanning and an exposure lamp of the scanner turns on after a prescribed period after the start of the movement of the scanner. When a rear edge of an original of the minimum size placed on a platen is irradiated by the scanning, an amount of irradiation of the exposure lamp attains a prescribed amount since the prescribed period has passed from the turn-on thereof. Accordingly, insufficiency of an irradiation amount of the exposure lamp does not occur at the time of original size detecting operation. Thus, detection operation is speeded up and the first copy speed of the image forming apparatus is improved.

摘要： When an image of content reproduced by a first reproduction device is shot, a content display support device obtains the shot image and positional information that specifies the position and orientation of a shooting device. The content display support device generates combination content by visualizing and embedding the positional information in the shot image and transmits the combination content to a second reproduction device. A portable terminal obtains the positional information from an image obtained by shooting the combination content reproduced by the second reproduction device. The portable terminal requests supplementary information by transmitting the positional information to the content display support device. The supplementary information associated with the positional information is transmitted from the content display support device to the portable terminal and displayed at the portable terminal.

摘要： A plurality of index members movable in a scanning direction of a scanner are arranged at desired positions on a front portion of a platen glass. A black mark is applied on the rear surface of each of the index member and the original as well as the mark are read by an image reader, so that the position of the index member is detected. When the index member is detected as the scanner moves, the image data of the original included in the scanning area scanned by the scanner are not stored in the bit map memory until the next index member is detected. When the scanning is completed, the desired edited images are formed on a paper whose size is determined based on the amount of the stored image data.

摘要： When a print switch is pressed, the color of the switch changes from green to orange. A wait indication prohibiting removal of an original placed on a platen glass is turned on. When reading of original images by an image reader is finished, the wait indication is turned off, permitting the removal of the original. Meanwhile, the color of the print switch is kept as it is until the end of image formation on a paper. The color of the print switch is turned into green when the image formation is finished, and the copying machine is returned to a stand-by state. Therefore, the next original can be set before the end of image formation, and the copying operation can be facilitated.

摘要： Relating to a solenoid used as a solenoid valve, a holding circuit and the like for suppressing the occurrence of back electromotive force, and preventing magnetic flux density from deterioration, without a major change of the conventional circuit constitution, is provided. A capacitor is connected in parallel with a resistance which is connected in series to a solenoid. The solenoid is driven at rated voltage by making a first switch and a second switch ON state and the solenoid is kept at holding voltage by making the first switch OFF state. The capacitor slows down the speed of change of applied voltage to the solenoid from the rated voltage to the holding voltage so that the back electromotive force of the solenoid is absorbed, which prevents the extinguishment of magnetic flux density.
