The present invention makes it possible to reduce the number of constituent components, and to provide a bobbin body having a smooth surface. A bobbin for a thermal transfer sheet or an image-receiving sheet includes a cylindrical bobbin body 11, wherein a gear 12 including a plurality of teeth 13 is formed on one side end of the bobbin body 11. Each tooth 13 of the gear 12 has a parallelogram shape as a whole, when viewed from a lateral side.

The cord reel device includes a reel body provided with a rotation shaft, a housing that stores inside the reel body in a rotatable manner, and a cord which is wound around the reel body so as to be extractable and which is extracted to an outside through an opening of the housing. The reel body has disk-shaped members on a plane perpendicular to the rotation shaft, and the cord is stored in a space formed between the disk-shaped members. A guide section inclined relative to the rotation shaft of the reel body is provided around peripheries of the disk-shaped members of the reel body. While the cord is wound around the reel body, the guide section guides the cord to the rotation shaft of the reel body.

A cap to be used with a plastic cable spool, said cap including a back side adapted to be arranged towards a barrel of a plastic cable spool and a front side adapted to be directed away from a barrel of a plastic cable spool, wherein said cap has a through-hole adapted to be aligned with a center axis of a cable spool, wherein said through-hole is at least partly surrounded by an inner wall on the back side of said cap, wherein said cap is provided with an outer wall extending around at least a part of said outer circumference of said cap, on the back side of said cap, and wherein said back side of said cap is provided with at least four reinforcement ribs extending between said outer wall and said inner wall.

A cable spool being provided with such a cap.

The present invention is an apparatus, system and method for a new and improved coiling head utilized in wrapping elongated materials, which may have a zero and or near zero gap between leaves thereby reducing and or elimination indentations in the coiled elongated materials.

A medium supporting device including a support part configured to support a roll body on which a sheet shaped medium is wound, a shaft serving as a rotary axis of the roll body and secured with the support part, and a driver configured to rotate the roll body supported by the support part. The shaft is secured to the support part by using a metal plate having a flat surface provided with an insertion hole, the insertion hole being a hole into which the shaft is inserted. An outer circumference part of the metal plate is restricted from moving in a rotation direction of the roll body relative to an inner circumference part of the support part.
