A transport device unwinds a medium from a roll body to which a shaft member is mounted and transports the medium. The transport device includes an accommodation portion configured to accommodate the roll body, a main body portion to which the accommodation portion is mounted, and a roller pair configured to nip the medium. The accommodation portion and the main body portion are relatively movable. The main body portion includes a rack configured to engage with a gear of the shaft member. The rack is engaged with the gear when the accommodation portion moves relative to the main body portion to be pulled out of the main body portion.

A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.

Provided is a printing apparatus including: a holder unit provided with a holding member, a contact portion, and a shaft member, and an apparatus body provided with a support portion, and a fixing portion, wherein the shaft member is configured to be detachably attached to the support portion, the holder unit is configured to be rotatable between a first position and a second position with reference to the shaft member in a state where the shaft member is supported on the support portion, the first position is a position where the shaft member is attached to the support portion, and the second position is a position where the apparatus body fixes the holder unit by the fixing portion, the second position being a position where the contact portion is separated from the installation surface.

A support spindle includes a central shaft defining a rotation axis and forming a connecting portion and a supporting portion extending from the connecting portion along the rotation axis, cam seats formed in the supporting portion, locking bodies arranged radially outside the supporting portion and in contact, by cam-follower members, with the cam seats, a supporting cage connected to the central shaft and which accommodates the locking bodies so the locking bodies can slide radially to the rotation axis with respect to the central shaft and rotate about the rotation axis with respect to the central shaft. A relative rotation between the locking bodies and the central shaft along an angular stroke causes a radial displacement of the locking bodies between a retracted position and an expanded position. The cam-follower members form a first convex cam surface in contact with a second concave cam surface of the corresponding cam seat.

A scarf-joint structure for the paper tube of a film dispenser is mounted in a film dispenser, which includes a frame connected with a film installation unit and an adjustment unit. The film installation unit is installed with a film roll and consists of a first positioning member and a second positioning member. The adjustment unit is formed with an operating part and a connecting part, and the operating part is connected with an adjusting member, which is threadably fixed with a screw fastener and further, an elastic member is mounted between the operating part and the connecting part. Thus, the film roll, the first positioning member and a second positioning member can be rotated synchronously, able to prevent the film roll from running idle, causing dislocation and falling off.

An Off-Road Rolling Film Vision System has a Controller Module (200), a Takeup Module (300), and a Rollout Module (400). The Controller Module (200) remotely controls a Motor (325) in the Takeup Module (300) with a Command Input (205) that has at least one Button to accept a knuckle bump for controlling a Motor (325) in the Takeup Module (300) when the Controller Module (200) is attached to a handlebar of an off-road vehicle. The Takeup Module (300) has a Motor Compartment (305), a Takeup Spool Compartment (310), a Takeup Spool Gear Compartment (315), a Takeup Film Window (320), a Motor (325), a Motor Gearbox (330), and at least one Takeup Spool Gear (340). The Takeup Module (300) may have a Takeup Spool Window (350) to provide a view of a Takeup Spool (345) within the Takeup Module (300).

A print medium feeding device removes a second sheet from a print medium that is in a state in which a first sheet, the second sheet, a the third sheet are superposed, superposes the first sheet and the third sheet, and feeds the first sheet and the third sheet to a printing device. The print medium feeding device includes: a first roller configured to come into contact with the third sheet and to be driven to rotate by movement of the third sheet; a second roller configured to come into contact with the first sheet and to be driven to rotate by movement of the first sheet; a roll-up member disposed upstream of the first roller and configured to roll up the second sheet; and a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member.

A one-piece integrally molded tape removal hub for a temporary tape removing apparatus which includes a length of cylindrical tube and a sleeve having a noncircular through bore extending into a portion of the cylindrical tube at an end thereof. A plurality of webs extend from the outer surface of the sleeve to the inner wall of the cylindrical tube. The portion of the cylindrical tube extending from the sleeve to the opposite end of the cylindrical tube is hollow.
