| 20080265498 | WORK SHEET CONVEYING DEVICE - The present invention provides a work sheet conveying device having a traveling member with a compact work sheet holder, making it possible to improve work sheet conveying speed and to reduce the time required for acceleration and deceleration, the work sheet conveying device further making it possible to improve the efficiency with which small work sheet's are conveyed. The work sheet conveying device includes a plurality of traveling members | 10-30-2008 |
| 20100019443 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image forming unit, a feeder unit, and a frame unit. The frame unit includes a pair of plate-like metal frames, each plate-like metal frame having an inner surface extending in a parallel direction to a sheet feeding path and in a perpendicular direction of a surface of a recording sheet, and a plurality of connecting frames connecting and holding the metal frames to be apart from each other. The image forming unit is arranged in space defined by the connecting frames and held by the metal frames to be substantially fitted in between the metal frames. The feeder unit is attached to an end of each of the metal frames by an attachment system provided on each widthwise side of the feeder unit. The attachment system fixes the feeder unit along a direction in parallel with the inner surfaces of the metal frames. | 01-28-2010 |
| 20100078881 | AUTOMATIC SHEET TRANSPORTING APPARATUS, AND AUTOMATIC DOCUMENT SCANNING APPARATUS WITH THE AUTOMATIC SHEET TRANSPORTING APPARATUS - An automatic sheet transporting apparatus includes a transporting unit with a discharge roller, the transporting unit discharge a sheet onto a discharge tray configured that support discharged sheets in a stack. A discharge guide, positioned on an upstream side of the discharge tray in a sheet discharging direction, guides a subsequent sheet transported by the transporting unit to a position between the discharge tray and a bottom surface of a previously discharged sheet in the stack. The discharge tray includes at least one rotating member that rotates when the discharge guide guides the subsequent sheet between the discharge tray and the bottom surface of the previously discharged sheet in the stack. The frictional resistance applied to the subsequent sheet is reduced to increase the number of sheets that can be stacked in the discharge tray. | 04-01-2010 |
| 20100133743 | SHEET FEEDING APPARUTUS AND IMAGE FORMING APPARATUS - The present invention complies a side end regulating mechanism to regulate a side end position in the width direction of sheets supported by a cassette main body | 06-03-2010 |
| 20100148430 | FEED DEVICE AND IMAGE FORMING APPARATUS - A feed device includes a paper tray on which sheets are stacked and a side fence that guides a side edges of a sheet stacked on the paper tray in a sheet feed direction. The feed device feeds an uppermost sheet from the sheets stacked on the paper tray to an image forming apparatus. A plurality of concavities and convexities integrally formed with an identical material to the side fence is formed on a surface of the side fence that is in contact with an edge face of a fed sheet. | 06-17-2010 |
| 20110163495 | Sheet Adjusting Device, sheet holding receptacle, image forming mechanism, and image reading mechanism - A sheet adjusting device applicable to a sheet holding receptacle, an image forming mechanism, and an image reading mechanism includes a sheet setting plate to place a sheet thereon; first and second regulating member to slidably move in a given direction, and a friction-reducing unit disposed on the sheet setting plate to reduce a frictional force on an underside of the sheet. Alternatively, a sheet adjusting device includes a sheet setting plate, a sheet contact face disposed downstream of the sheet setting plate to cause the leading edge of the sheet abuts against the sheet contact face, first and second regulating member, and a friction-reducing unit disposed on the sheet contact face to reduce a frictional force on the sheet contact face and the leading edge of the sheet. | 07-07-2011 |
| 20110210501 | PAPER FEEDING CASSETTE AND IMAGE FORMING APPARATUS - The rear end face of the first upright portion of a trailing edge regulating member is brought into contact with the inner face of a notched sidewall provided in a rear sidewall, and the second upright portion is located above the notched sidewall. | 09-01-2011 |
| 20110298175 | PAPER FEEDING DEVICE - According to one embodiment, a paper feeding apparatus arranged along the left-right direction on one side of an image forming apparatus and configured to feed stacked sheets one by one in order from a top sheet to the image forming apparatus from a paper feeding side adjacent to the image forming apparatus includes: a base plate; a tray on which plural sheets are stacked; a front-side guide member; a rear-side guide member; a paper-feeding-side guide member; an opened section formed by opening one side opposite to the paper-feeding-side guide member; and an auxiliary front guide member configured to regulate a position on the front end side of the sheets. The auxiliary front guide member has a sheet guiding section configured to come into contact with a corner on the front side of the sheets placed deviating from a proper placing state and guide the corner to the auxiliary guide section. | 12-08-2011 |
| 20120001385 | SHEET STACKING APPARATUS AND IMAGE FORMING APPARATUS - An image forming apparatus has a sheet stacking apparatus including a tray on which sheets are stacked, and an aligning member aligning the sheets stacked on the tray. The aligning member aligns sheets stacked, on a sheet previously stacked on the tray, with a displacement in an aligning direction of the aligning member with respect to the sheet previously stacked. An aligning operation of the aligning member is changed on the basis of whether or not the number of the sheets stacked on the sheets previously stacked is a predetermined number or less. | 01-05-2012 |
| 20130285317 | IMAGE FORMING APPARATUS - An image forming apparatus includes an engagement member provided on a sheet supply cassette, a biasing member with a first part, a second part and an elastic part formed of elastic material. The first and second parts are linked with the elastic part. The second part is supported to a apparatus main body with a swing shaft. The first part engaging with the engagement member so that the biasing member maintains a compressed state by the engagement member, and a guide restriction member provided on the apparatus main body restrict a movement of the first part. | 10-31-2013 |
| 20160062295 | SHEET STACKABLE DEVICE AND IMAGE FORMING APPARATUS - A sheet stackable device including a sheet stackable bin and a first edge guide is provided. The first edge guide is slidable in a first direction. The sheet stackable bin includes a first rail to guide the first edge guide, a second rails to guide the first edge guide, and teeth arranged along the first direction. The first edge guide includes a first protrusion configured to contact the first rail along a second direction orthogonal to the first direction, a second protrusion configured to contact the second rail, a locking part engageable with the teeth, and a handle to disengage the locking part from the teeth. The handle is arranged in a position between the first rail and the second rail with regard to the second direction. | 03-03-2016 |
