  • Patent number: 10341517
    Abstract: In an image forming apparatus, a first motor causes a first rotor to rotate. The first motor rotates based on a first drive signal. A second motor causes a second rotor to rotate. The second motor rotates based on a second drive signal. A reading unit is provided between the first rotor and the second rotor. Based on a read signal, the reading unit reads a paper sheet being conveyed line by line. In a first period, a read signal generation unit generates the read signal in accordance with a frequency of the first drive signal. In a second period, the read signal generation unit generates, as the read signal, a signal for reading the paper sheet being conveyed at a reference speed.

  • Patent number: 10310427
    Abstract: An image forming apparatus includes a display, a display controller, a cover, a cover sensor, a recording sheet sensor, and a jam solution work progress managing unit. The display controller causes the display to continuously display a guidance video in a process sequence when the recording sheet jam occurs. The guidance video shows a work procedure constituted of a plurality of processes for a solution work for a recording sheet jam. The jam solution work progress managing unit manages a progress of the solution work for the recording sheet jam. When the jam solution work progress managing unit determines that the solution work for the recording sheet jam is not performed while the cover sensor detects closing of the cover, the display controller causes the display to repeatedly display a guidance video showing a work procedure for a first process in the solution work for the recording sheet jam.

  • Patent number: 9791821
    Abstract: A document conveyance apparatus includes a document conveyance section, a cover, an opening and closing detection sensor, a document detection sensor, and a control section. The control section detects opening and closing of the cover on the basis of an output value of the opening and closing detection sensor and detects whether or not there is a document in a predetermined detection position on the basis of the output value of the document detection sensor. If, when the output value of the document detection sensor has changed from a value indicating an opened state of the cover to a value indicating a closed state thereof, the output value of the document detection sensor is a value indicating that there is the document, the control section detects a half-closed state where the cover is not completely closed.
