  • Patent number: 10730712
    Abstract: A conveyance apparatus is capable of detecting the presence or absence of multi feeding with high accuracy even when a received waveform varies due to a “noise from the circuit” and an “influence due to vibrations,” which are fixedly generated noise components. The conveyance apparatus includes an original conveying motor configured to convey an original; an ultrasonic transmitter, which is arranged at one of positions sandwiching a conveyance path along which the original is conveyed, and transmits an ultrasonic wave toward the conveyance path; and an ultrasonic receiver, which is arranged at the other one of the positions sandwiching the conveyance path, and receives the ultrasonic wave transmitted from the ultrasonic transmitter. The conveyance apparatus compares a received wave amplitude exhibited with sheet-presence against a threshold value determined based on a received wave amplitude exhibited with sheet-absence to determine whether the original is conveyed with multi feeding.

  • Publication number: 20200207570
    Abstract: A sensor control apparatus includes a control unit, a plurality of sensors connected in series to the control unit. Each of the plurality of sensors includes a detector configured to perform a detection operation based on a first voltage applied from the control unit, a first switch provided on an application path for applying a voltage, a second switch provided on a supply path for supplying the voltage applied from the control unit to a sensor connected in a subsequent stage, and a conduction control unit. The control unit brings the first switch into conduction and cut off the second switch in a case where the voltage on the application path is the first voltage, and cuts off the first switch and bring the second switch into conduction in a case where the voltage on the application path is a second voltage.

  • Patent number: 10573891
    Abstract: The object of the present invention is to provide a carbonaceous material which is obtainable from plant-derived char and has a decreased specific surface area. Further, the object of the present invention is to provide a non-aqueous electrolyte secondary battery having excellent dedoping capacity, non-dedoping capacity, and charge-discharge efficiency. The object can be solved by a carbonaceous material for non-aqueous electrolyte secondary batteries characterized in that the carbonaceous material is obtained by heat-treating plant-derived char which is demineralized in gas-phase, and carbon precursor or volatile organic compound under a non-oxidizing gas atmosphere; and a specific surface area determined by a BET method is 10 m2/g or less.

  • Patent number: 9981819
    Abstract: A transmitter transmits ultrasound to the conveyance path. A receiver receives the ultrasound. A double-feed detector detects whether or not double-feed of a plurality of sheets has occurred. A controller causes the transmitter to transmit ultrasound at a first burst interval when determining the threshold value, and causes the transmitter to transmit ultrasound at a second burst interval, which is shorter than the first burst interval, when detecting the double-feed of sheets. A double-feed detector determines a threshold value that enables distinction between double-feed and single-feed.

  • Patent number: 8203761
    Abstract: When an auto document feeder feeds an original to an original image reading platen, a CCD line sensor reads the original along the main scanning direction perpendicular to the feeding direction of the original. A string detection circuit detects a streak parallel to the feeding direction in the image. A string correction circuit corrects the detected streak. In particular, for a predetermined number of sub-scanning positions that are located in the same main scanning position as the main scanning position at which the streak has been detected by the string detection circuit and that exist subsequent to the sub-scanning position at which the streak has been detected, correction is performed by the string correction circuit even when no streak is detected by the string detection circuit.

  • Patent number: 7920197
    Abstract: An image pickup apparatus includes the following units. An image pickup unit captures an image and outputs an analog image signal. A conversion unit converts the analog image signal into a digital image signal. A synchronization signal generation unit generates a synchronization signal to be supplied to the image pickup unit and the conversion unit, and supplies the synchronization signal to the image pickup unit. An adjustment unit adjusts the timing at which the synchronization signal generated by the synchronization signal generation unit is supplied to the conversion unit, and supplies the synchronization signal to the conversion unit. The adjustment unit is disposed in a position such that the adjustment unit is affected by the self-heating of the image pickup unit.
