A driving device includes a motor, a drive gear, a swing gear, a first gear member, a second gear member, a frame, and a bracket. The swing gear can swing between a first position engaging with the first gear member and a second position engaging with the second gear member. The bracket has a slide hole including a pair of contact parts having an arc shape, and an arc hole part for connecting the pair of contact parts with a first sliding surface farther from the drive gear and a second sliding surface nearer to the drive gear. The first sliding surface has a shape retracting to the opposite side to the rotation shaft from tangential lines of the rotation shaft contacting with the contact parts, which are parallel to pressure angle directions between the drive gear and the swing gear, or a shape coinciding with the tangential lines.

A printing device includes a housing, a print head, a platen roller, a holder, and a cover. The housing has a cassette attaching opening through which a printing cassette accommodating a printing tape is attachable to the housing. The holder holds one of the print head and the platen roller. The holder is movable between a nip position in which the print head and the platen roller nip the printing tape and a non-nip position in which the print head and the platen roller do not nip the printing tape. The cover is attachable to the housing. The cover is movable between a covering position to cover at least part of the cassette attaching opening and an engaged position to engage with the housing. The holder moves from the non-nip position to the nip position in conjunction with movement of the cover from the covering position to the engaged position.

A media processing device includes: a print head extending across a media path, and configured to apply indicia to media; a platen roller assembly adjacent to the print head, the print head configured to draw the media from a media supply along the media path travelling between the print head and the platen roller assembly, the platen roller assembly including: (i) a first platen roller extending across a first portion of a width of the media path, and (ii) a second platen roller coaxial with the first platen roller, and extending across a second portion of the width of the media path; a drive assembly coupled with the first and second platen rollers, the drive assembly configured to selectively drive rotation of either or both of the first and second platen rollers.

A system for stretching a surface of a shoe for digitally printing onto the surface by an external device, the system comprising an apparatus and a controller in electrical communication, the system having: a main plate to receive and support the shoe; a side arm to traverse longitudinally along an edge of a medial portion of the main plate and to engage with at least a portion of the tongue of the shoe; and a driver causing the longitudinal traversal of the side arm, having: an end bearing and an end connector; a rotary band; an end bracket opposite the end bearing and beneath the main plate; a driving screw between the end bracket and the end bearing, and associated with the side arm; and a motor adapted to receive an electrical signal from the controller selectively causing a rotation of a rotary shaft of the motor.

A printing device includes: a base; a printing platform, the printing platform being connected to the base; a printing bracket, the printing bracket being fixed on the base; and a printing head assembly, the printing head assembly being connected to the printing bracket and being arranged above the printing platform, and the printing head assembly including a bearing member, a discharging assembly and an optical assembly. The discharging assembly and the optical assembly are both arranged on the bearing member, the discharging assembly is used for providing printing materials of at least two colors for the printing platform, and the optical assembly is used for curing the printing materials on the printing platform. The printing device can implement three-dimensional color printing.

A recording apparatus includes a recording head that performs recording; a feeding roller that feeds out a medium that has been set, a transport roller that transports the medium fed out by the feeding roller toward a facing position facing the recording head; an auxiliary roller that is provided between the feeding roller and the transport roller and that assists in the transport of the medium; a motor that generates a driving force; and a drive train that is configured to transmit the driving force of the motor to the auxiliary roller and the transport roller.
