Sheet feeding apparatus, image reading apparatus and image forming apparatus
A holding member is configured to hold a feed member and movable up and down. A lever member is configured to pivot on a pivot shaft and includes a contact portion configured to be in contact with the holding member. An elastic member is connected to the lever member and configured to urge the holding member downward through the lever member. The elastic member is disposed such that, when viewed in an axial direction of the pivot shaft of the lever member, a distance from the pivot shaft to a line of action of a force applied by the elastic member to the lever member in a case where the feed member is located at a first position is shorter than a distance from the pivot shaft to the line of action in a case where the feed member is located at a second position below the first position.
IMAGE RECORDING DEVICE HAVING A COMPACT FORM FACTOR
An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.
MEDIUM CONVEYING APPARATUS TO CORRECT SKEW OF MEDIUM USING SECOND ROLLER WHILE MOVING FIRST ROLLER TO BE SPACED APART FROM MEDIUM
A medium conveying apparatus includes a first roller to convey a medium, a movement mechanism to move the first roller between a first position in contact with the medium and a second position spaced apart from the medium, a second roller located on a downstream side of the first roller in a medium conveying direction to convey the medium, and a processor to detect a skew of the conveyed medium, and control the movement mechanism to move the first roller to the second position, and correct the skew of the medium using the second roller when the skew of the medium is detected.
Presentation device for presenting a ticket from a printer
A presentation device for presenting a ticket from a printer includes first and second reels, a ticket holder and a housing component. In operation, the first reel contacts a first side of the ticket, and the second reel contacts a second side of the ticket opposite to where the first reel contacts the first side of the ticket. As the ticket advances from the presentation device, gravity pushes the ticket down onto the ticket holder, which is a reel. The first reel, the second reel and the ticket holder are secured in the housing component. The housing component is pivotable about a rotating axis and has a supporting notch that supports the second reel. The supporting notch has a first guide edge surface that faces away from the rotating axis, a second guide edge surface, and a trough between the first guide edge surface and the second guide edge surface.
Sheet processing machine with shaping device and upper suction transport means
A sheet processing machine has at least one shaping device and at least one sheet delivery unit, arranged downstream of the at least one shaping device along a transport path provided for a transport of sheets. The at least one shaping device has at least one shaping point which is formed by at least one forme cylinder, on one hand, and at least one impression cylinder, on the other hand. At least one separation device, for removing scrap pieces from sheets, is arranged downstream of the at least one shaping point along the transport path provided for the transport of sheets. The at least one separation device has at least one separation transport device. At least one transport device, configured as a selective transport device, is arranged following the at least one separation transport device along the transport path provided for the transport of sheets. The transport device is configured as at least one upper suction transport device for a hanging transport of sheets.
Sheet conveying apparatus and image forming apparatus
A sheet conveying apparatus includes a sheet conveying member; a guide portion configured to define a sheet conveying path; a pressing portion configured to press the sheet to curve the sheet as viewed in a sheet conveying direction in the sheet conveying path; and a moving portion movable by an edge of the sheet passing through the sheet conveying path and arranged so that at least a part of a movable range of the moving portion is overlapped with the pressing portion. The moving portion includes a first abutment portion configured to abut against the sheet passing through the sheet conveying path on one side in the width direction with respect to a conveyance center of the sheet conveying member and a second abutment portion configured to abut against the sheet passing through the sheet conveying path on the other side with respect to the conveyance center.
RECORDING APPARATUS
There is provided a recording apparatus including: a medium support section that supports a medium before feeding; a feeding roller that sends out the medium; and an apparatus main body, in which the medium support section is configured to switch between a stored state of being stored in the apparatus main body and a protruding state, being a state where an upstream part in a feeding direction protrudes from a first side surface of the apparatus main body, in the protruding state of the medium support section, close to a second side surface, which is a side surface opposite to the first side surface, an assist roller that applies a sending force to the medium fed from the medium support section is provided upstream of the feeding roller in the feeding direction.
Paper sheet accumulating device and control method of paper sheet accumulating device
A paper sheet accumulating device includes an accumulating part in which paper sheets are accumulated, an impeller that sends the paper sheets to the accumulating part, and a support mechanism that supports the impeller. The support mechanism includes a first rotation shaft that supports the impeller rotatable, a support member provided with the first rotation shaft, a second rotation shaft that supports the support member rotatable in a direction of the support member moving toward and away from the accumulating part, and a biasing member that biases the support member in a direction of the impeller moving toward the paper sheets accumulated in the accumulating part.
MEDIUM CONVEYING APPARATUS IN WHICH SEPARATION FORCE OF SEPARATION ROLLER BY GEAR WITH RESPECT TO PRESSING FORCE OF SEPARATION ROLLER BY TORQUE LIMITER IS SET APPROPRIATELY
A medium conveying apparatus includes a torque limiter provided on a rotation axis of the separation roller, a unit including a first gear, a second gear provided on the rotation axis, and a third gear provided between the first gear and the second gear. The separation roller is pressed toward a feed roller side by a force generated by the torque limiter. The first gear rotates in a direction for generating a force for separating the separation roller from the feed roller. The third gear is a two-stage gear. The number of teeth of a gear on the second gear side of the third gear is more than the number of teeth of a gear on the first gear side of the third gear.
Image recording apparatus
An image recording apparatus for recording an image on a sheet includes a recording section which records the image on the sheet in a transport passage for transporting the sheet in a transport direction and multiple plates which are spaced apart from each other in a widthwise direction. These multiple plates include a first type of plate and a second type of plate. Plates of a first type of plate are configured to overlap a sheet when viewed in a direction perpendicular to the transport direction and the widthwise direction, while plates of the second type of plate do not.
