Problems solved by technology

[0014] In addition, especially when the long side of a large (for example, A3 size) paper is conveyed along the medium conveyance direction, if the paper is in a state of "horizontal grain", the curl formation speed of the front end of the large paper is fast, Front end tends to curl up and may not stack properly on the media tray

Embodiment 1

[0051] First, an outline of a recording apparatus according to an embodiment of the present invention will be described. In this embodiment, an inkjet printer 1 (hereinafter, simply referred to as printer 1 ) is exemplified as an example of the recording device.

[0052] figure 1 is a perspective view showing the appearance of the printer according to Embodiment 1. figure 2 yes figure 1 Side sectional view of the printer shown. image 3 is a side sectional view showing the paper conveyance path of the printer. Figure 4 It is a perspective view of the appearance of the discharge tray, and is a figure in which the second receiving part is in the first state. Figure 5 It is a perspective view of the appearance of the discharge tray, and is a figure in which the second receiving part is in the second state. Figure 6 It is a side view of the discharge tray, and is a diagram showing a transition between the first state and the second state of the second receiving unit. Fi...

Embodiment 2

[0106] In this example, based on Figure 12 as well as Figure 13 Another example of the printer according to the present invention will be described. Figure 12 is a block diagram showing the control system of the printer according to Embodiment 2. Figure 13 It is a figure which looked at the switching unit according to Example 2 from the lower surface side. In the present embodiment, the same components as in the first embodiment are given the same symbols, and descriptions of the components are omitted.

[0107] In Embodiment 1, switching is performed by manually operating the switching unit 30 that switches the state of the second receiving unit 26 in the paper discharge tray 5, but in the printer 40 of Embodiment 2, it is configured to automatically switch according to the size and type of paper. The state switching of the second receiving unit 26 is performed accordingly.

[0108] More specifically, as Figure 12 As shown, the printer 40 is configured to include a ...

Abstract

Provided is a recording apparatus, when a medium is discharged from a recording apparatus main body, which can achieve both of appropriate mounting of a medium in which the leading edge thereof is curled on a medium receiving tray, and reduction of damage to a medium when mediums of different sizes are mixed on the medium receiving tray.

Description

[0001] The entire contents of Japanese Patent Application No. 2016-229115 filed on November 25, 2016 are hereby incorporated by reference. technical field [0002] The present invention relates to a recording device for recording on a medium. Background technique [0003] Among the recording devices represented by inkjet printers, there is a recording device that is configured such that a discharge unit such as a discharge roller is provided on the downstream side of a recording unit that records on paper as a medium, and the recorded paper is are ejected to the outside of the device, and are stacked (accumulated) in the order of ejection on a media receiving tray (sometimes called a stacker, etc.) that receives ejected multiple sheets. [0004] However, when a liquid (ink) is ejected onto the paper to perform recording, the paper may be curled so that the recording surface is located outside. In general, paper has grain (a flowing texture of fibers formed when paper is man...
