A feed mechanism includes: a feed tray accommodating a roll body, a first sheet-shaped medium being rolled in a roll shape as the roll body, the feed tray including: a first accommodation portion accommodating the roll body; a pair of side walls respectively provided on both sides of the first accommodation portion in an axial direction of the roll body that is accommodated in the first accommodation portion; and a side guide disposed inside the pair of side walls.

Techniques for implementing and/or operating a pipe deployment system that includes pipe deployment equipment, which facilitates deploying a pipe segment from a pipe coil, and a pipe drum, which includes a drum body around which the pipe coil is to be disposed. The pipe drum is to be disposed on the pipe deployment equipment and the drum body includes a drum core as well as a lower paddle assembly and an upper paddle assembly, which are slidably secured to the drum core. The pipe deployment system maintains the paddle assemblies in a retracted state to enable the drum body to be inserted into the pipe coil, extends the lower paddle assembly to a more extended state to facilitate raising the drum core, and retracts the lower paddle assembly to a less extended state and extends the upper paddle assembly to the less extended state to facilitate lifting the pipe coil.

A roll paper steering device includes a guide rail fixed to a main body frame, a guide engaged with the guide rail, a holding shaft fixing member supported by the guide rail via the guide, a roll paper holding unit including a roll shaft and mounted to the holding shaft fixing member, a movable member configured to adjustably mount to the holding shaft fixing member, a nut member that includes an internal thread portion that screws into the external thread portion and that is fixed to the main body frame in a posture where the axis of the external thread portion is parallel with the guide rail, a first adjustment unit configured to adjust the posture of the holding shaft fixing member, and a second adjustment unit configured to adjust the position at which the movable member.

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.

An unwinder of reels of web material wound around winding spindles (A), includes a unwinding station (13) with at least one unwinding member (23) to rotate a reel (B) that is located in the unwinding station and feed the web material toward a delivery path (E). Lifting members (51, 53) are provided to lift a spindle of a first exhausted reel from the unwinding station (13), in a removal position (PR). An insertion member (7; 33) is further provided to insert a second reel into the unwinding station (13). A pressing member (61) is arranged to press the web material coming from the first reel in removal position (PR) against the second reel in the unwinding station (13).
