Disclosed is a sheet feeding device for feeding a sheet from a roll sheet, including: a holder portion that rotatably supports the roll sheet around which the sheet to be fed is wound; a guide portion that guides the roll sheet to the holder portion; a rear member that is included in the guide portion and projects from the holder portion in a projection direction; and a front member that is included in the guide portion and is connected to the rear member to be capable of projecting from the rear member in the projection direction. The front member is configured to be movable in the projection direction with respect to the rear member.

A pivot mechanism for a printer is provided, the pivot mechanism comprising a pivot base and two oppositely disposed side walls extending perpendicular to the pivot base. An arched slot may be provided in each side wall. Each slot may have at least two notches, each notch defining different positions of the pivot mechanism. Two lever arms may be provided, each of the two lever arms comprising a first end and a second end, with a connecting rod connecting the first ends of the lever arms together. A locking pin may be disposed on the second end of each of the lever arms. Each of the locking pins may extend into a corresponding one of the slots and engage with a corresponding notch. A pivot rod extends through the lever arms and into or through the side walls. The printer housing is adapted to pivot on the pivot rod.

Methods and apparatus for supporting a paper roll in a paper bucket of a printer are provided. The paper bucket may comprise a curved base portion for accepting paper rolls of varying widths, two oppositely disposed side walls movably mounted to the curved base portion, and a two-part spring-loaded spindle assembly extending through each of the side walls and adapted to support a paper roll therebetween. Each spindle assembly may comprise a first spring loaded spindle part and a second spring loaded spindle part movably connected to one another.

A dispensing roll lock device comprises at least one rod and end caps designed to attach to ends of the rods. The rod is sized to be inserted through end locks on sides of a dispensing box and through the roll in the box. The end caps secure the rod in the box so that the roll of the dispensing box is secured in the box when dispensing material from the roll.

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 printing apparatus is configured to perform in a first mode in which a second driving unit drives a second spool to feed out a sheet from a roll to a printing unit via a second guide, the printing unit performs printing on the fed sheet, and a basket unit receives the printed sheet printed on by the printing unit, and a second mode in which a first driving unit drives a first spool to feed the out the sheet from a roll to the printing unit via a first guide, the printing unit performs printing on the fed sheet, and the second driving unit drives the second spool to wind up the printed sheet printed by the printing unit as a roll.

A waste disposal device has a container having an opening at a top end, the container defining an inner cavity accessible through the opening. A bag interface at the opening is adapted to hold a bag opened at the opening of the container with a closed end of the bag extending in the inner cavity. A pair of doors is pivotally connected to the container to open and close access through the opening and adapted to close off a portion of the bag passing therebetween, the doors being pivotable from a closed position in which the doors meet to close the access through the opening, to a first pivoted position in which the doors are pivoted away from the inner cavity. One or both doors is or are pivotable to a second pivoted position toward the inner cavity. An actuation mechanism biases the door(s) to the closed position.

A pet feces bag dispenser and carrying apparatus is provided comprising a first portion forming a first open base of a truncated hexagonal pyramid with faces extending upward from the base to an opening at the top forming an first inner open volume. A second portion forming a second open base, six faces of the second hexagonal pyramid extending downward from a second base opening thereby forming a second inner open volume including a solid bottom plane formed at a common top edge of the second faces. Two axels are affixed at opposing points on inner surfaces of the first portion enabled to hold a roll of feces bags, and an end of the roll extends up through the opening. The bases come together in a closed position aligned together with a hinged side opposite a means for keeping the bases adhered together in the closed position.

A support apparatus to secure a mass loaded vinyl roll on a scaffold above a ground surface dispenses mass loaded vinyl from the roll with enhanced efficiency for an application on a wall. The support apparatus includes a frame assembly having a pair of upright legs coupled to a generally horizontal bar, each upright leg in the pair of upright legs having a top end with a U-shaped member coupled thereto, a pair of clamps mounted to the horizontal bar to secure the frame to the scaffold, and a spool bar coupled to the U-shaped members of the pair of upright legs and designed to secure the mass loaded vinyl roll thereon.

A method for managing the continuous feeding of an elongate element wound on reels to a station for building a tire, wherein the elongate element is continuously supplied from an unwinding device of successive reels. When the terminal end of the elongate element wound on a first reel leaves said first reel, the method provides for: the first reel to be moved away from the unwinding device on a first movable carriage; a second reel, successive to the first reel, and mounted on a second movable carriage, to be positioned in place of the first reel; and the terminal end of the elongate element previously wound on the first reel, to be joined to the starting end of the elongate element wound on the second reel.
