  • Publication number: 20190383939
    Abstract: An object capturing device includes light emission, receiving, and scanning units, and distance calculation, and object determination units. The scanning unit measures light from the emission unit to head toward a measurement target space to perform scanning, and to guide reflected light from the object with respect to the measurement light to the receiving unit. The distance calculation unit calculates a distance to the object in association with a scanning angle of the scanning unit. The object determination unit determines whether the object is a capture target based on whether a scanning angle range within which a difference between distances is equal to or less than a predetermined threshold value corresponding to a reference scanning angle range of the capture target, and a determination of whether intensity distribution of the reflected light within the scanning angle range corresponds to reference intensity distribution of the reflected light from the capture target.

  • Patent number: 10068607
    Abstract: A base portion of a motor includes an inner bottom plate portion, a recessed portion and groove portions recessed upward from a lower surface of the inner bottom plate portion, and at least one through hole passing through the inner bottom plate portion in an axial direction. The groove portions extend from the recessed portion toward land portions of a circuit board on a lower surface of the base portion. Conducting wires are drawn out from coils above the base portion to a draw-out surface through the at least one through hole, and are passed through communicating openings and the groove portions to be soldered to the land portions. Each of the at least one through hole is covered with the sealant. Drawing the conducting wires out of the recessed portion through the groove portions prevents the sealant in the recessed portion from overflowing toward the land portions.

  • Patent number: 7688465
    Abstract: An information managing apparatus assigns identification information to print information and manages the print information based on the identification information. A receiving section receives a plurality of items of data. A first counter is defined in a non-volatile first memory. A second counter is defined in a volatile second memory. An identification information producing section produces the identification information for each of the plurality of items of data based on a count of the first counter and a count of the second counter. An identification information managing section manages the plurality of items of data based on the identification information. The second counter counts up by a value every time the receiving section receives an item of data, and the first counter counts up when the image forming apparatus is turned on, and when the second counter overflows.
