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.

A credential production device includes a processing path, a transport mechanism, a processing assembly and at least one assembly guide. The transport mechanism is configured to feed individual substrates along the processing path. The processing assembly includes a supply spool support, a take-up spool support, a plurality of ribbon supports, and a print head or a transfer roller. Each assembly guide is configured to guide movement of the processing assembly substantially perpendicularly to the processing path between an operating position and a loading position relative to the processing path.

A ribbon cassette includes a case, an ink ribbon, a first spool, a second spool, a rotating member, a clutch spring, and an engaging part. The ink ribbon has one end portion wound over the first spool and another end portion connected to the second spool. The rotating member is engaged with a first inner surface of the first spool. The clutch spring includes a coil like annular part attached to the rotating member, and an extension part extending from the annular part. The engaging part is positioned on a locus of rotation of the extension part. The first spool has a protrusion provided at a second inner surface of the first spool. The case-hole is in communication with an interior of the first spool, and has a portion overlapped with an entire circular region surrounded by a path of rotation of the tip end of the protrusion.

A printhead assembly structured to be removably received into a printhead guide of a media processing device having a platen and a biasing assembly, the printhead assembly comprising a printhead and a support body. The support body is adapted to support the printhead. The support body is structured to slidably translate within the printhead guide between a disengaged position, where the printhead is removed from the platen, and an engaged position, wherein the printhead is positioned proximate the platen. The support body defines an interface member structured to removably engage the biasing assembly.
