  • Patent number: 10343863
    Abstract: This sheet feeding device includes a paper transport path, a first paper pass detection unit, a second paper pass detection unit, a transport processing mechanism, an actuation determining section, and a detection control section. The first paper pass detection unit detects that the paper passes through a first point on the paper transport path. The second paper pass detection unit detects that the paper passes through a second point on the paper transport path. The transport processing mechanism performs predetermined transportation processing on the paper traveling on the paper transport path. The actuation determining section determines whether the transport processing mechanism has been actuated. The detection control section controls the first paper pass detection unit to constantly perform detection, and, if the actuation determining section detects that transport processing mechanism has been actuated, controls the second paper pass detection unit to perform detection except for a certain time period.

  • Patent number: 9296580
    Abstract: Provided are an auto document feeder (ADF), a scanner including the ADF, and a method of controlling auto document feeding. The ADF includes: a feed unit picking up a sheet of paper and carrying the sheet of paper to a scan unit; a feed control unit controlling the feed unit; and a retry control unit. If a sheet of paper is not normally picked up by the feed unit, the retry control unit decreases a speed of a motor driving the feed unit or increases a current supplied to the motor for picking up the sheet of paper. Therefore, although sheets of paper are not normally fed when a user intends to use various kinds of sheets of paper with the ADF, the retry control unit may stabilize feeding of the feeding of the sheets of paper. Thus, efficient, convenient, and high-quality paper feeding may be possible.

When the first stack is exhausted, the second stack is moved by an actuator towards a position where the lift plate was loaded with the first stack of media sheets. Movement of the second stack displaces a biased gate to decouple the lift plate from a drive member that elevated the lift plate. The lift plate drops under the effect of gravity to a position where the second stack of media sheets moves onto the lift plate.

  • Patent number: 8002261
    Abstract: A starting unit starts, in parallel with a blowing operation for a first tray, a blowing operation for a second tray that is to perform a feeding operation next. When a predetermined time elapses after starting the blowing operation for the second tray, a feeding unit switches from the first tray to the second tray, and feeds the recording medium from the second tray. When the blowing operation is performed for a number of trays before switching the trays and the number of trays is equal to or larger than a predetermined number, a control unit limits the number of trays for performing the blowing operation.

  • Patent number: 7976011
    Abstract: When a first feeding unit is not ready to perform air feeding at the beginning of a print job, roll feeding using a second feeding unit is performed; when it is determined that the first feeding unit is ready to preform air feeding, air feeding using the first feeding unit is preformed. Upon execution of a print job by roll feeding, a preparation is started to make the first feeding unit ready to air feeding. When the first feeding unit is ready to execute the print job by air feeding, the print job is executed by exchanging roll feeding to air feeding using the first feeding unit.

  • Patent number: 7959147
    Abstract: A sheet feeding apparatus includes a switchable transmission mechanism disposed between a pickup roller and a driving source, and switches the driving source between a first state for rotating in the forward direction to rotate the pickup roller, and a second state for not rotating the pickup roller, the forward direction is opposite to a direction in which the driving source is rotated to rotate a feeder roller in a sheet feed direction. The sheet feeding apparatus also includes a control portion rotating the driving source in the forward direction to rotate the pickup roller in a sheet supply direction, and switches the switchable transmission mechanism between the first state, when a sheet is supplied from a sheet holding portion, and the second state, when the sheet is fed by the feeder roller.

  • Patent number: 7931264
    Abstract: In a case that it is determined that a first feeding unit is not ready to feed upon designation of a first print job that requires air feeding, start of the first print job is waited until the first feeding unit is ready to feed. In a case that a second print job that requires roll feeding is accepted during waiting for the first print job, the second print job is executed, and the first print job that requires air feeding is executed after completion of the second print job.

  • Patent number: 7857301
    Abstract: A sheet feed device includes a motor that rotates in a first and second direction, a first transmitting mechanism having an upstream and a downstream portion, that transmits a rotational force in a first transmitting direction, a second transmitting mechanism having an upstream and downstream portion, that transmits the rotational force in a second transmitting direction, a first idling mechanism, and a second idling mechanism. When the motor transitions between rotating in the first direction and rotating in the second direction, the first idling mechanism allows the upstream portion of the first transmitting mechanism to perform an idle rotation with respect to the downstream portion of the first transmitting mechanism, and the second idling mechanism is configured to allow the upstream portion of the second transmitting mechanism to perform an idle rotation with respect to the downstream portion of the second transmitting mechanism.

  • Patent number: 7789389
    Abstract: A media dispenser has a delivery module for feeding media, a stacking module for stacking the media, which are fed through the delivery module, on a stacking plate, and a delivery clamp module for clamping the media stacked on the stacking module and delivering the clamped media to the customer, and for feeding the media, which the customer did not take out, to the stacking plate. A path through which the media clamped by the delivery clamp module are fed to a reject box is opened by moving the stacking plate of the stacking module. The method comprises the steps of returning the media onto the stacking plate by a clamp assembly, opening a reject slot by allowing a driving plate to be moved by a driving source and the stacking plate to be moved together with the driving plate, and dropping the media as the clamp assembly unclamps the media through the opened reject slot.

  • Patent number: 7761046
    Abstract: Mechanism unit(s) functioning as automatic-feed cassette(s) and mechanism unit(s) functioning as manual-feed tray(s) together form a single integral module, constituting a hybrid paper supply module. A plurality of hybrid paper supply modules are stacked together to constitute a paper supply mechanism. Manual-feed tray(s) with which manual-feed mechanism unit(s) of respective hybrid paper supply module(s) is or are provided is or are maintained in stored state(s) as a result of electromagnetic attraction produced by electromagnet(s). In correspondence to image forming condition(s), electromagnetic attraction at one electromagnet is terminated, causing manual-feed tray(s) to assume deployed state(s). Furthermore, primary path(s) passing vertically through module interior(s) is or are formed so as to permit transport of recording paper toward printing unit(s) of hybrid device(s) regardless of from which hybrid paper supply module(s) it is that recording paper is taken up.
