  • Patent number: 10399802
    Abstract: A sheet feeding apparatus includes a damper mechanism having a movable portion supported by a sheet storage portion and movable with respect to the sheet storage portion by abutting against a body in a case where the sheet storage portion is inserted to the body, and a resistance member. In addition, a first transmission portion actuates the resistance member to produce a resistive force and transmits the resistive force so that an insertion speed of the sheet storage portion is reduced when the sheet storage portion is inserted to the body, and a second transmission actuates the resistance member to produce the resistive force and transmits the resistive force so that a lowering speed of the sheet supporting member is reduced when the sheet storage portion with the sheet supporting member having been lifted by a lift portion is drawn out of the body.

  • Patent number: 8939274
    Abstract: An envelope feeder for a printer having two aligned conveyors moving at different speeds is disclosed. An upstream conveyor moves a backwards slanted procession of envelopes having aligned upper edges onto an inline downstream conveyor that accelerates the envelopes along a curved upper edge so that by the time any single envelope arrives at the printer ingestion or feed slot, the envelope is almost completely flat yet supported upwards slightly so that the pickup roller of the printer can easily and reliably ingest the envelope for processing. Due to the speed of the downstream conveyor, envelopes are continually and reliably presented to the printer to avoid printer stalls. The configuration reduces the amount of skill and operating labor required to establish a high-speed envelope feed source for high-speed printing.

    Abstract: A remaining amount detector measures beforehand a distance H where there is one sheet. A motor displaces a lifting plate to a paper-feeding position upon storing paper in the feeding unit. The remaining amount detector measures a distance y1 to the lower face of a paper stack. Thereafter, upon transport of paper from the stack, a control unit causes the remaining amount detector to measure a distance y2 for every predetermined number n of fed sheets. A remaining sheet calculation unit calculates a displacement y1?y2=?y to the bottom of the paper stack S, and calculates the thickness of one sheet on the basis of the displacement ?y and the number n of fed sheets (t=?y/n). The remaining sheet calculation unit divides the thickness (H?y2) of the paper stack by the thickness t of one paper sheet, and calculates the number of remaining sheets m as (m=((H?y2)/t)+1).

    Abstract: In a media tray, a mid-tray sensor is located relatively equally distant between the tray front and the tray back. This allows the tray to be free of a divider between the front and reserve stack areas. After the user closes the tandem tray, an elevator plate lifts media in the lead stack location and a slider moves in a forward direction toward the tray front based on the front media sensor not detecting media in the front stack area, or whenever the mid-tray sensor detects media located between the front stack area and the reserve stack area. An alarm is produced when the front media sensor does not detect any media, or when the slider is unable to move when it should be able to move (forward into the front stack area, back through the reserve stack area, etc.).

  • Patent number: 8550452
    Abstract: A sheet feeder has a sheet accommodating portion, a lift plate, an actuating plate, and an actuating plate driving member. The lift plate is supported on the bottom face of the sheet accommodating portion such that an end part of the lift plate is rotatable. The actuating plate raises and lowers the lift plate by moving between a first position where it lies flat along the bottom face of the sheet accommodating portion and a second position where it is raised a predetermined angle from the bottom face of the sheet accommodating portion. The actuating plate driving member has the actuating plate fixed thereto. The engagement portion is provided on the reverse face of the lift plate, and engages with the actuating plate when this is in the first position and disengages from the actuating plate as the actuating plate rotates from the first position to the second position.

  • Patent number: 8540236
    Abstract: A remaining amount detector measures beforehand a distance H where there is one sheet. A motor displaces a lifting plate to a paper-feeding position upon storing paper in the feeding unit. The remaining amount detector measures a distance y1 to the lower face of a paper stack. Thereafter, upon transport of paper from the stack, a control unit causes the remaining amount detector to measure a distance y2 for every predetermined number n of fed sheets. A remaining sheet calculation unit calculates a displacement y1?y2=?y to the bottom of the paper stack S, and calculates the thickness of one sheet on the basis of the displacement ?y and the number n of fed sheets (t=?y/n). The remaining sheet calculation unit divides the thickness (H?y2) of the paper stack by the thickness t of one paper sheet, and calculates the number of remaining sheets m as (m=((H?y2)/t)+1).
