  • Publication number: 20220086296
    Abstract: An automatic document feeder includes a document loading detector, a document feeder, a document guide, a guide width measurer, a document width acquirer, a guide shift determiner, a document skew detector, a skew determiner, a warning display information generator, and a display. When a detected skew of a document is determined to be unallowable, the document feeder stops a feeding of the document. The warning display information generator generates a warning content about a feed trouble that stopped the feeding of the document, and the generated warning content about the feed trouble is displayed on the display.

  • Publication number: 20220060590
    Abstract: According to an automatic document feeder of a multifunction peripheral according to the present invention, two tilt sensors are provided in the middle of a document conveyance path to detect a tilt degree of a document being conveyed along the document conveyance path. Here, for example, if the positional deviation representing the tilt degree of the document is greater than a predetermined threshold value ?Ls, the conveyance of the document is stopped. On the other hand, if this is not the case, the conveyance of the document is continued. In addition, the threshold value is set in accordance with the width dimension of the document, and in particular, the larger the width dimension, the smaller the threshold value.

  • Patent number: 9900457
    Abstract: An image forming apparatus has a power-saving mode in which the image forming apparatus is switched from a normal power consumption state to a low power consumption state where less energy is supplied than in the normal power consumption state. This image forming apparatus includes a detection unit configured to detect an operating state of the image forming apparatus, and a memory unit configured to store a detection result by the detection unit. In the power-saving mode, the detection unit detects an operating state of the image forming apparatus, and the memory unit stores a detection result by the detection unit. When the image forming apparatus returns from the low power consumption state in the power-saving mode to the normal power consumption state, control of a return operation for the image forming apparatus from the power-saving mode is executed, based on the detection result by the detection unit stored in the memory unit.

  • Patent number: 8366096
    Abstract: A document reader has a main conveying path, an auxiliary conveying path, a pickup roller, a first conveying roller, and a second conveying roller. The auxiliary conveying path runs between a first connection point and a second connection point on the main conveying path. The cylindrical surface of the first conveying roller is located partially on the main conveying path and partially on the auxiliary conveying path. While the first conveying roller is under the forward or reverse control, it rotates normally. The cylindrical surface of the second conveying roller is located partially on the main conveying path between the second connection point and a discharge position. A controller switches from the forward control selected during this mode to the reverse control, while a document being conveyed along the main conveying path is out of contact with the first conveying roller.

  • Patent number: 8274711
    Abstract: When reading of the documents set on the document feed tray is given priority by user designation, the documents set on the document feed tray are read first, then the document set on the platen plate is read. When reading of the document set on the platen plate is given priority, the document set on the platen plate is read first, then the documents set on the document feed tray are read. Even when originals are composed of documents that can be set on the document feed tray and an original that cannot be set on the document feed tray, use of the above configuration makes it possible to achieve copying of the originals as one job.

  • Patent number: 8016284
    Abstract: An operation of a pickup roller to be performed upon powering on or after paper jam elimination is adjusted according the presence or absence of a document on a document sheet support. When the document is absent on the sheet support, the pickup roller is moved down sufficiently and then moved up by a first distance to assume an upper limit position. When the document is present on the sheet support, the pickup roller is moved up by a second distance which is shorter than the first distance.

  • Patent number: 7391334
    Abstract: A connection checking system of the present invention is arranged so as to apply a power supply voltage which is dropped by the resistance to a terminal when the control substrate and the unit are connected. Then, the control section determines that the unit is connected to the control substrate when the dropped voltage is applied to the terminal. On the other hand, when a dropped voltage is not applied to the terminal, the control section determines that the unit is not connected to the control substrate. The connection checking system of the present invention can be realized by using a conventional power supply cable, a signal cable and a terminal, and thus the connection checking system of the present invention can be manufactured at low costs.

  • Publication number: 20080055252
    Abstract: To provide an operation panel apparatus which can be used without exchanging the whole operation panel, even when input of a part of an input apparatus cannot be performed. In a test mode, a plurality of fixed keys 7 are in sequence checked on whether or not the input of the plurality of fixed keys 7 can be performed. A detecting portion 18 judges the fixed key as an input-enabled fixed key 7a by detecting that the input from the fixed key 7 is sensed, and judges the fixed key as an input-disabled fixed key 7b by detecting that the input from the fixed key 7 is not sensed. When the input-disabled fixed key 7b exists, a substitute control portion 19 displays a touch key 5a substituting for the function of the input-disabled fixed key 7b in a display screen.
