  • Patent number: 10875728
    Abstract: A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes multiple position detectors and a position corrector. The multiple position detectors are aligned along a sheet conveying direction and configured to detect a side end of a sheet. The position corrector is configured to convey the sheet and correct a position of the sheet based on a positional deviation amount of the sheet, obtained by a detection result of the multiple position detectors. The positional deviation amount of the sheet is obtained by an extreme downstream position detector in the sheet conveying direction, of the multiple position detectors. A position of a subsequent sheet is corrected based on a sum of the positional deviation amount of the sheet and a positional deviation amount of the subsequent sheet.

  • Patent number: 10710812
    Abstract: A physical distribution system includes first and second conveyance paths, first and second sensors, and a processor. The first sensor detects a package passing along the first conveyance path. The second conveyance path merges with the first conveyance path at a junction. The second sensor detects a package passing along the second conveyance path. The processor counts a first number of packages present in a first convergence monitoring section determined in the first conveyance path upstream the junction, and counts a second number of packages present in a second convergence monitoring section determined in the second conveyance path upstream the junction, determines an order in which packages in the first and second convergence monitoring sections pass the junction, based on the first number and the second number, and control the first and second conveyance paths, such that the packages pass the junction in the determined order.

  • Patent number: 10625670
    Abstract: Provided is a notification device and notification method that reduce the output and power consumption of an amplifier or the like and allow a user to sufficiently feel the presence or absence of notification through vibration. A notification device (1) includes a sweep signal generator (4) configured to generate a detection sweep signal by continuously changing the frequency in a frequency band in which a speaker (6) can cause a user to feel a signal in the form of vibration, a vibration detector (7) configured to detect vibration outputted from the speaker (6), and a sound measurement unit (8) configured to detect, as a sweep frequency band, a frequency band in which vibration indicates signal levels equal to or higher than a threshold. The sweep signal generator (4) generates a resonance sweep signal by changing the frequency in the sweep frequency band and causes the speaker (6) to generate vibration.
