Problems solved by technology

However, depending on the specification of the recording head, the recording medium may not be fed from different directions to the recording head.
In addition, due to design limitations of the main body of the recording device, the plurality of retractors may not be installed at positions far apart from each other.
In such a case, the prior art is worried about the contact between the recording media, so a plurality of retractors are not mounted on the recording device.

Abstract

The invention provides tractors, a tractor unit and a recording device. According to the recording device, a plurality of tractors which can convey recording medium are arranged adjacently. The tractor module (101) for conveying papers (2) is provided with the components as following: a gear (117) bearing a driving force from the side the the printer body (10) of a printer (1); tractors (120, 130) which sending continuous papers (2) outwardly along a preset direction through the rotation of the gear (117); and a frame work (111) which guide the continuous papers (2) from the exterior relative to the tractors (120, 130).

Description

technical field [0001] The present invention relates to a tractor that conveys a recording medium, a tractor unit equipped with the tractor, and a recording device including the tractor unit. Background technique [0002] Conventionally, there is known a recording device that includes a tractor that conveys a recording medium, and records on a recording medium that is conveyed by the tractor. Such a recording device is equipped with a plurality of retractors (for example, refer to Patent Document 1). The recording device described in Patent Document 1 can be used by switching a plurality of tractors. For example, in this recording device, the recording medium used can be changed by selecting the tractor used. Thereby, an arbitrary recording medium can be selected from among a plurality of recording media and used without taking out the recording medium from the tractor. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 64-8071 [0004] However, in a r...
