Automatically adjustable pick mechanism for feeding sheets of media of different widths

摘要

In an imaging apparatus, a removable media tray is operative to hold a plurality of media types of different widths and a pick device includes a pick mechanism and a translation mechanism for moving the pick mechanism to a centerline of a width of one or more media sheets in the media tray. The media tray includes a reference edge surface and a media edge guide moveable to a selected position with respect to the reference edge surface. The one or more media sheets are restrained between the reference edge surface and the media edge guide with the translation mechanism automatically translating the pick mechanism to the centerline of the corresponding media width during insertion of the media tray into the imaging apparatus.

1. A media picking device for an imaging apparatus having a removable media input tray configured to hold a plurality of media types of different widths, the media input tray having a reference edge surface and a media edge alignment guide moveable to a selected position with respect to the reference edge surface and further moveable to an edge of one or more media sheets disposed in the media input tray to restrain the one or more media sheets between the reference edge surface and the media edge alignment guide such that a distance therebetween corresponds to a width of the one or more media sheets, the media picking device comprising:
a pick mechanism slidably mounted on a torque supplying shaft in the imaging apparatus; and a translation mechanism comprising:
a carriage coupled to a portion of the pick mechanism and slidably attached to a platform within the imaging device; andan actuator member slidably attached to the platform and operatively coupled to the carriage, the actuator member engageable and moveable by the media edge alignment guide upon insertion of the media input tray into the imaging apparatus, wherein, when the media input tray is being inserted into the imaging apparatus, the media edge alignment guide engages the actuator member to translate the carriage and the pick mechanism along the shaft so as to position the pick mechanism between the reference edge surface and the media edge alignment guide about a centerline of the width of the one or more media sheets, and further wherein the pick mechanism and the carriage translate in the same direction as the actuator member a distance that is substantially half of a distance traveled by the actuator member.
