Disclosed is a drawing apparatus including: a base member; and a drawing member that is attached so as to be capable of being drawn and pressed in a reciprocating direction with respect to the base member, wherein the base member has a couple application mechanism that applies a couple for correcting skewing of the drawing member with respect to the reciprocating direction to the drawing member as a reaction of a force by which the drawing member is pressed, and wherein the couple application mechanism is configured so that a distance between action lines of two forces generating the couple becomes large as a pressing amount of the drawing member with respect to the base member increases.

A medium discharge device includes: a discharge unit that discharges a medium; a first medium receiving tray that receives the medium discharged by the discharge unit; and a second medium receiving tray that is provided above the first medium receiving tray in a vertical direction and receives the medium discharged by the discharge unit. The second medium receiving tray is capable of changing a position between an advance position for receiving a medium, which is discharged, by causing at least an upstream zone of the tray including an upstream side end portion in a medium discharge direction to advance to a passing route of the medium from the discharge unit toward the first medium receiving tray and a retraction position to which the upstream zone retracts from the passing route.

A sheet storage device has a rotation restriction portion configured to restrict a rotation of an end cursor from a first posture to a second posture. The rotation restriction portion has: a restriction piece situated on the end cursor and configured to be brought into contact with a guide rail so as to restrict the rotation of the end cursor from the first posture to the second posture; and an engagement recess formed at a given position of the guide rail, the restriction piece being fitted in the engagement recess. The end cursor is allowed to rotate from the first posture to the second posture when the restriction piece is fitted in the engagement recess at the given position of the guide rail.

The sheet feeding device includes a feed roller, a separation pad and a guide part. The feed roller is configured to feed a sheet by being rotated while coming into pressure contact with the sheet. The separation pad is configured to form a separation nip by being in pressure contact with the feed roller and to separate the fed sheet at the separation nip. The guide part is configured to guide a leading edge of the sheet to the separation nip. The apex part is formed along a feeding direction of the sheet on both outer sides of the feed roller in a width direction perpendicular to the feeding direction. The apex part projects in a direction closer to the feed roller than an extension line of the separation nip between a pressure contact position of the feed roller and the sheet and the separation nip.

An image recording apparatus including a first tray having a first holding portion for holding sheets, a second tray disposed above the first tray and including a second holding portion for holding sheets, a sheet feeder that selectively feeds a sheet from one of the first tray and the second tray in a sheet feed direction, a recording unit that records an image on the sheet fed by the sheet feeder, and a discharge roller that discharges the sheet on which the image is recorded by the recording unit. The second holding portion of the second tray moves above the first holding portion of the first tray. The second tray further includes a discharged sheet receiving portion for receiving the sheet discharged by the discharge roller. The second tray including the discharged sheet receiving portion pivots relative to the first tray.
摘要:
A removable media tray with a two-axis media restraint system having a user-actuated rear media restraint operatively coupled to a side media restraint via a camming member. The rear media restraint includes a latching assembly for slidably latching with one of the indents along a track, each indent corresponding to a supported media length. The camming member having a predefined camming profile surface is coupled to and movable with the rear media restraint. As the rear media restraint moves along the track, camming member moves with the rear media restraint in the same direction engaging first and second cam follower portions of the side media restraint causing the side media restraint to move to contact a side edge of a media stack with the position of the side media restraint depending on a position of the first and second cam follower portions on the camming profile surface.

Printing apparatus comprise a printing table, a loader to load sheets of print media to the printing table, and a moveable tray on which at least one row of media sheets can be placed, the tray being moveable between a position in which it is accessible to an operator for placing media sheets thereon and another position in which at least part of the tray is accessible to the loader for picking the print media sheets but inaccessible to the operator.

A sheet feed cassette monitor includes an actuator with another end portion, a detecting circuit, a plurality of protrusions, a signal monitoring circuit, and a signal determining circuit. When the one end portion is in contact with a paper sheet, the other end portion swings in a first direction. When the one end portion is not in contact with the paper sheet, the other end portion swings in a second direction opposite direction to the first direction. The detecting circuit detects the swinging of the other end portion on the actuator. The plurality of protrusions are convexly installed in an asymmetric manner with respect to a putting-in/taking-out direction of the feed cassette. The signal determining circuit determines a presence/absence state of the paper sheet housed in the sheet feed cassette and an open/close state of the sheet feed cassette based on a pattern of change in the monitored signal.
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.
