A roll-dispensed stock container is provided with fixation strips attached to the body of the container and a cutter assembly attached to a lid of the container. Roll-dispensed stock is secured by the fixation strips when the lid of the container is in a closed configuration and the cutter assembly is configured to separate a sheet of the roll-dispensed stock of a desired length.

In one example, a holder for a media roll includes a first support to support a first end of the roll, a second support to support a second end of the roll, and a shifter to change the distance between the first support and the first end of the roll without changing the distance between the second support and the second end of the roll.

According to the present disclosure, a first guide unit is provided with a first opening portion through which light in an optical path connecting a first optical element unit and a second optical element unit passes, a second guide unit is provided with a second opening portion through which light in the optical path connecting the first optical element unit and the second optical element unit passes, the first guide unit is provided with a duct for sending air to the first optical element unit, and the air coming out from the first opening portion hits the second optical element unit via the second opening portion.

A sheet feeding apparatus includes a sheet regulation member, a lock portion, and a damper portion. The sheet regulation member is changeable between a regulation posture to regulate a sheet supported on a supporting portion not to enter a separation nip portion and a retracted posture to allow the sheet to enter the separation nip portion. The lock portion locks the sheet regulation member in the regulation posture. In a case where external force equal to or more than a predetermined amount is applied to the sheet regulation member toward the downstream in the sheet feeding direction with the sheet regulation member is locked by the lock portion in the regulation posture, the damper portion allows displacement of the sheet regulation member.

A sheet conveyance device includes a shape detecting portion, and a switch control portion. The shape detecting portion detects a shape of a sheet at a detection position between a first conveyance member and a second conveyance member. The switch control portion, when a front end of the sheet has passed a arrangement position at which the first conveyance member is arranged, switches an detection interval at which the shape of the sheet is detected by the shape detecting portion, to a first interval that corresponds to a rotation speed of the first conveyance member, and when a rear end of the sheet has passed the arrangement position, switches the detection interval to a second interval that corresponds to the rotation speed of the second conveyance member.

A sheet supporting apparatus includes a body, a supporting portion configured to be held in an elevating manner by the body and to support a sheet, a sheet regulation portion regulating a position of the sheet supported on the supporting portion, a movement portion capable of moving between a first position where the sheet regulation portion regulates the position of the sheet supported on the supporting portion, and a second position where the supporting portion is regulated from elevating with respect to the body, and a movement regulation unit regulating the movement portion from moving to the second position.

In a sheet processing apparatus including a guide member that rotates by contact with a sheet processing unit, collision of the sheet processing unit with the guide member in a rotating state is avoided. A sheet conveyance apparatus includes: sheet processing units that move along one movement path intersecting a conveyance direction of a sheet; guide members that each include a fixed end rotatable about a rotation center line and support the sheet from below; a biasing member that biases the guide member so as to return to an original orientation in which a part of the guide member is located on the movement path; and a collision determination unit that determines, before at least one of the sheet processing units is moved and based on a movement start position and a target position of a movement target sheet processing unit and a size and an orientation before start of movement of the guide member, whether or not there is a possibility of occurrence of collision of the movement target sheet processing unit with the guide member in a rotating state.

A spindle mechanism of a winding machine includes a spindle box provided with a mounting hole; bearings respectively arranged at both ends of the mounting hole of the spindle box to form a front bearing and a rear bearing, the bearing comprises an inner ring and an outer ring; and a spindle, the spindle is arranged to pass through the mounting hole of the spindle box and is rotatably positioned on the spindle box by means of the bearings, and the number of the front bearings is the same as the number of the rear bearings, and the outer ring of at least one of the front bearing and the rear bearing is not restricted in an axial direction so as to form a free end.

According to one embodiment, a sheet post-processing apparatus has a sheet discharge tray, a drive motor, a power transmission breaker, a first power transmitter, a second power transmitter, and a load reducer. The sheet discharge tray stacks sheets. The drive motor raises and lowers the sheet discharge tray. The power transmission breaker can cut off power transmission from the drive motor to the sheet discharge tray when an upward external force is applied to the sheet discharge tray. The load reducer provides a reverse load to the sheet discharge tray in a reverse direction to the load generated on the sheet discharge tray due to stacking of the sheets. The load reducer is connected to the first power transmitter.

Roll-dispensed stock containers are provided. The roll-dispensed stock containers can include a recessed cutting track positioned along a length of a support wall of the container. The support wall can also include one or more apertures positioned adjacent to the recessed cutting track configured to receive a base of a slidable cutter movable along an elongated slot in a lid of the container. The base of the slidable cutter is captured by the recessed cutting track during a cutting operation to secure the lid in a closed position and to apply constant pressure against roll-dispensed stock as it is cut. Roll-dispensed stock containers of the present disclosure can also include a coating on one or more surfaces thereof. The coating can be formed from a material selected to reduce surface friction, increase rigidity, disperse forces associated with a cutter, and/or otherwise enhance characteristics of the container.
