Problems solved by technology

[0007] However, the biasing force of the torsion coil spring 150 is uneven with respect to the preset biasing force due to the unevenness of the product of the spring 150 itself or the installation error of the installation to the conveying device 100 .
As a result, the pressure contact force of the feed roller 120 to the paper Q is uneven.

Embodiment Construction

[0033] Below, refer to Figure 1 to Figure 9 , the specific embodiment of the conveying device used as an inkjet printer (hereinafter referred to as "printer") will be described. In addition, in the following description, unless otherwise specified, the use of "front-rear direction", "up-down direction" and "left-right direction" means figure 1 The "front-back direction", "up-down direction" and "left-right direction" indicated by the middle arrows. In addition, in this embodiment, the vertical direction is defined as the same direction as the vertical direction.

[0034] Such as figure 1 As shown, the printer 11 is a recording device that records characters, images, and the like on paper as a conveyed medium supplied from the rear side. The printer 11 includes: a conveying device 12 that is an Auto Sheet Feeder (ASF: Auto Sheet Feeder) for conveying paper; a recording device 13 that records an image or the like on the paper conveyed by the conveying device 12; The paper...

Abstract

The invention provides a transportation device, capable of preventing the double feeding of the transported media. The transportation device includes a pick-up unit having a first arm that is rotatable about a first rotation section, a second arm that is rotatable about a second rotation section with respect to the first arm and is provided with a feeding roller fixed thereon, and a torsion coil spring that acts on the second rotation section so as to bias the feeding roller toward the paper sheets. The first arm has a first fixation section that fixes in place one end of the torsion coil spring, while the second arm has a second fixation section that fixes in place the other end of the torsion coil spring. A plurality of spring latches is disposed on at least one of the first fixation section and second fixation section so as to adjust a spring force of the torsion coil spring.

Description

technical field [0001] The present invention relates, for example, to a conveying device for an inkjet printer or the like. Background technique [0002] Conventionally, a printer is provided with a conveying device for separating and feeding paper (a medium to be conveyed) one by one from a bundle of paper placed on a loading tray of the printer. In such a transport device, in order for the feed roller to reliably feed the paper, the feed roller is pressed against the paper to maintain a state where the feed roller is in pressure contact with the paper (for example, refer to Patent Document 1). [0003] refer to Figure 10 The configuration of a conventional conveying device will be described. [0004] The transport device 100 is provided with a loading tray 110 on which the paper Q is placed, and a feed roller 120 for transporting the paper Q placed on the loading tray 110 to the recording unit of the printer. The feed roller 120 is mounted on a drive shaft 140 as a driv...
