Abstract

The invention provides a print device that can transport an item to be transported such as a recording medium at a high accuracy, a transport unit, a transport roller and a method of providing the transport roller. The print device includes a transport roller for transporting a recording medium in which a pair of end surfaces of a metallic plate faces each other so as to be molded in a cylindrical shape, wherein at least one end surface of the pair of end surfaces includes a first portion which comes into plane contact with the other end surface of the pair of end surfaces at an outer periphery surface side of the transport roller, and a second portion which has a gap between the second portion and the other end surface at an inner periphery surface side thereof.

Description

technical field [0001] The present invention relates to a printing device, a conveying unit, a conveying roller, and a method for manufacturing the conveying roller. Background technique [0002] Conventionally, a printing device for printing information on a sheet-like recording medium is used, and such a printing device is provided with a transport unit for transporting the recording medium. Such a transport unit has transport rollers that transport recording media. Typically solid rod-shaped elements are used for the conveyor rollers. The recording medium is held on conveying rollers and conveyed by the conveying rollers rotating. In addition, since the recording medium is printed while carrying out such conveyance, the recording medium needs to be conveyed and positioned with high precision in order to perform accurate printing. [0003] On the other hand, a solid material causes problems of high weight and cost, so technologies for further reducing weight and cost ar...
