A recording apparatus includes a printing unit that performs a recording on a sheet, a third sheet feed unit that mounts a roll body on which the sheet is wound in a roll shape, unwinds the sheet from the roll body, and supplies the sheet to the printing unit, and a pressing portion that presses the roll body mounted on the third sheet feed unit, in which the pressing portion presses the mounted roll body in a direction opposite to a direction of taking out the roll body from the third sheet feed unit.

The present disclosure provides an apparatus for manufacturing a superfine fiber roll wiper for a cleanroom, wherein a thermal cutting unit including thermal cutting blocks and thermal cutters is applied to a thermal cutting part, such that a process of manufacturing a roll wiper and a process of thermally bonding both ends of the manufactured roll wiper may be performed by the single apparatus, as a result of which, with the use of the single apparatus, it is possible to considerably improve workability, implement the mass-production, and reduce manufacturing costs. Further, the thermal cutting unit further including interval adjustment blocks in addition to the thermal cutting blocks and the thermal cutters is applied, such that a width of a roll wiper to be manufactured may be selectively and conveniently adjusted when a change in width of the roll wiper is required.

In a movable portion state being a state of a print movable portion including a roll core holder unit configured to support one end portion and another end portion of a roll core, there exist an open state and a closed state. The print movable portion is configured to be movable so that the movable portion state is the open state or the closed state. The roll core holder unit is provided with a support portion. In a support state in which the support portion supports the one end portion and the another end portion, as the movable portion state transitions from the open state to the closed state, a first fitting portion fits into the one end portion and a second fitting portion fits into the another end portion.

A printing apparatus includes: a main body; a cover; a pair of supporters including a movable supporter; a first urging member configured to urge the movable supporter in an approach direction; an engaging member movable between a separated position and an engaged position; and a second urging member configured to urge the engaging member toward the engaged position. When the cover is in an open state, the engaging member is located at the engaged position by an urging force of the second urging member so as to inhibit movement of the movable supporter in the approach direction. When the cover is in a closed state, the engaging member is located at the separated position against the urging force of the second urging member by contact of the cover with the engaging member so as not to inhibit the movement of the movable supporter in the approach direction.

A device for holding a coil structure that is wound in multiple coils. The device includes a coil clamp that retains the coil structure and a base substrate that the coil clamp engages in order to support the coil clamp and, in turn, the coil structure. The coil clamp is formed as a single piece coil clamp that includes a main circular portion and a base substrate engagement portion that is contiguous with the main circular portion. The main circular portion is arranged for receipt of the coil structure, and said base substrate engagement portion has a retaining recess for receiving and engaging with a side edge of the base substrate. The container box is preferably constructed of a cardboard material, and a part, or all of, the container box, is foldable and useable as the base substrate.

A media roll holder assembly for a roll is detachably supported in a printing system. A rotational drive includes a roll engaging element configured for fittingly engaging and driving a drive engaging element of a roller, for example an Oldham coupling. A first guide surface is configured to support and direct the roller in a loading direction. A second guide surface at least partially extends at an angle with respect to the first guide surface, such that movement of the roller over the first guide surface brings the drive engaging element in contact with the second guide surface. The second guide surface directs the drive engaging element into a predetermined orientation, which orientation aligns the drive engaging element with the roll engaging element in a loading orientation, such that further movement of the roller in the loading direction inserts the drive engaging element into the roll engaging element.

In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.

A safety chuck mounted to equipment that process web material is provided. The safety chuck is provided with a die spring connecting a moveable jaw with a spindle, said spring urging the moveable jaw into a fully closed position. A number of magnets mounted on a mounting flange will engage the moveable jaw, overcoming the spring's force and holding the moveable jaw in a fully open position. Rotation of the spindle releases the magnets allowing the spring to force the moveable jaw back into a fully closed position.

To provide a spindle supporting a roll body on which a sheet-shaped medium is wound and rotationally driving the roll body. The spindle includes a shaft member to be inserted into the roll body, a gear fixed on a tip side of the shaft member in an axial direction, a spacer member contacting both of the shaft member and the gear, and a coupling member coupling the shaft member to the gear. In the axial direction of the shaft member, a contact area of the spacer member and the gear is larger than a contact area of the shaft member and the spacer member. The gear is coupled to the coupling member in the axial direction and the shaft member is coupled to the coupling member in an intersecting direction intersecting the axial direction.
