MEDIUM HANDLING
Medium handling apparatuses and methods of media handling, both for use in printing devices, are disclosed herein. An example of a medium handling apparatus includes a first transport roller to convey a medium and a first drive mechanism to rotate the first transport roller at a first rate. This example of the medium handling apparatus additionally includes a second transport roller to convey the medium and a second drive mechanism to rotate the second transport roller at a second rate. This example of the medium handling apparatus further includes a coupling assembly to disengage the second transport roller from the second drive mechanism to allow the medium to rotate the second transport roller at the first rate.
Conveyor and ink-jet recording apparatus
A conveyor includes: a slide gear and a clutch gear including a first gear and a second gear. The clutch gear includes: a first surface and a second surface provided on one of the first and second gears and facing each other; and a contact member provided on the other of the first and second gears and located between the first surface and the second surface. A controller is configured to: control a motor in a state in which the slide gear and the first gear are in mesh with each other, to rotate the clutch gear to establish a state in which the contact member is not in contact with the first surface or the second surface; and control a sliding mechanism to slide the slide gear in the state in which the contact member is not in contact with the first surface or the second surface.
Sheet folding device, image forming apparatus and gear coupling mechanism
A sheet folding device includes two rollers, a blade, two parallel pins, and two gears. The first and second parallel pins are passed through first and second pin through-holes penetrating through first and second shaft portions in a direction perpendicular to a longitudinal direction of the shaft portions. The first and second gears have first and second shaft through-holes through which the first and second shaft portions are passed, and first and second grooves in which the first and second parallel pins are inserted, respectively. Projection portions formed on inner side wall of the second groove and projecting from both sides of the second shaft portion cause the second parallel pin to closely contact a side wall that is, in the second groove, opposite to the projection portions, and cause the second parallel pin to closely contact a portion of the second pin through-hole.
Sheet conveyor and image forming apparatus
A groove has a first side surface and a second side surface. The second side surface faces the first side surface and is located downstream of the first side surface in a first direction. The first side surface has a first contact surface configured to contact one side surface of a protrusion. The second side surface having a second contact surface and a guide surface. The second contact surface is smaller than the first contact surface. The second contact surface is configured to contact an other side surface of the protrusion. The guide surface is inclined away from the first contact surface in a direction from a tip-side end of the second contact surface toward a tip end of a drive shaft. The tip-side end is an end facing toward the tip end of the drive shaft. The guide surface is configured to guide the protrusion to the groove.
Image forming apparatus and supplying device
An image forming apparatus includes a storing-device body that is drawable from an image-forming-apparatus body, a supporting member attached to the storing-device body and that supports a stack of recording media from below, a feeding member that feeds a top one of the recording media on the supporting member into the image-forming-apparatus body, a moving mechanism that moves the supporting member such that the top one of the recording media on the supporting member comes into contact with the feeding member, a connecting mechanism that connects the moving mechanism to a drive source in conjunction with attaching of the storing-device body to the image-forming-apparatus body, an image forming section that forms an image on the recording medium fed by the feeding member, and a disabling mechanism that disables connection between the drive source and the moving mechanism in conjunction with pushing of the storing-device body into the image-forming-apparatus body.
Stripper assembly
A stripper assembly can include a feed wheel, a stripping tire, a drag clutch, and first and second stripping elements. The feed wheel and stripping tire can be mounted for rotation in clockwise (CW) and counter-clockwise (CCW) directions and can contact one another to define a nip through which papers are directed. The drag clutch can be interposed between the stripping tire and the shaft it is mounted upon. The first and second stripping elements can be positioned on the shaft of the stripping tire on opposite sides of the nip. Each of the stripping elements can be configured and positioned to engage papers passing through the nip. The drag clutch is not interposed between either of the first and second stripping elements and the shaft of the stripping tire.
SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS INCLUDING SAME
A rotation member is divided into a first detection region and a second detection region. A first interval in the circumferential direction between the detection target located at the tail end of the first detection region in the main rotation direction and the detection target located at the front end of the second detection region in the main rotation direction is less than a second interval in the circumferential direction between the detection target located at the tail end of the second detection region in the main rotation direction and the detection target located at the front end of the first detection region in the main rotation direction.
Cable Reel Stands Usable for Hoist Rope Replacement in Electric Rope Shovels
An improved cable reel stand for rotational support of a cable reel comprising a spool and a length of cable wound thereon, which spool is carriable by an axle spanning axially through said spool. Two stanchions of the stands carry two respective axle cradles, of which on is neighboured by a brake selectively couplable to the axle by a coupling of non-circular profile that cooperates with non-circular internal profiles of the brake and the axle to provide rotational interlocking thereof. The axle cradles are roller cradles serving to self-align the axle into a properly seated position atop two adjacent cradle rollers, and are equipped with hold-downs for positive capture of the seated axle. The axle features a circumferential V-groove for mating with tapered cradle rollers at one of the axle cradles.
Dispensing system and a dispenser
A dispensing system includes a roll comprising a keyed end, a dispenser comprising a housing for receiving the roll, and a mount comprising a roll holder to support the keyed end and a roll support to support an opposing end. The roll holder comprises a frame, a clutch plate, a spindle, and a biasing unit, the clutch plate being disposed adjacent the spindle, and the spindle receives the keyed end and is rotatably coupled to the frame to permit rotation of the roll and the clutch plate about the dispensing axis. The spindle comprises a clutch surface and translates along the dispensing axis, and the biasing unit biases the spindle along the dispensing axis away from the frame. Mounting the keyed end of the roll onto the mount pushes the spindle towards the frame to increase a normal force between the clutch plate and the clutch surface.
Power transmission apparatus, medium transport apparatus, recording apparatus, control method of power transmission apparatus, and control method of medium transport apparatus
A power transmission apparatus includes a drive source, a power transmission switching section configured to switch between a transmission state in which power of the drive source is transmitted to a driven section and a non-transmission state in which power of the drive source is not transmitted to the driven section, a load switching section configured to switch between a first load state, which is a load while the driven section is driven, and a second load state, which is a load smaller than the load of the first load state, and a control section, wherein the control section switches the power transmission switching section from the non-transmission state to the transmission state while the load is in the second load state, and then uses the load switching section to switch the load from the second load state to the first load state.
