Problems solved by technology

Therefore, in the structure of Japanese Patent Laid-Open No. 2013-146893, the air flow between the recording head and the recording medium cannot be increased.
That is, the airflow between the recording head and the recording medium does not increase, so it is impossible to prevent paper dust and the like from adhering to the recording head and clogging the discharge port, thereby impairing the image quality

no. 1 approach

[0024] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. First, the notch part of the mounting part supported by the partition between the first head box and the second head box, which is the main part of the structure of the present invention, and the part between the first head box and the second head box will be described. Flow path used to provide air flow. Also, the configuration of a liquid discharge recording device (hereinafter also simply referred to as a recording device) for realizing these parts will be described.

[0025] figure 1 A schematic diagram of a recording device to which this embodiment can be applied is shown. In addition, in figure 1 , cut the main body shell at the appropriate horizontal position with respect to the bottom surface of the main body. The carriage 5 carries the recording head 1 and is movable. The recording head 1 mounted on the carriage 5 discharges liquid (hereinafter also r...

no. 2 approach

[0051] Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In addition, since the basic structure of this embodiment is the same as that of 1st Embodiment, only a characteristic structure is demonstrated below.

[0052] Figure 8 (a) and (b) are schematic cross-sectional views of the carriage and the head cassette in this embodiment viewed from the sheet discharge side. Such as Figure 8 As shown in (a), as long as there is a slit 16 on either side of the mounting portion 14 on the spacer 17, part of the air flow from the flow path 18 will be supplied between the head cartridge and the recording medium, and the recording head can be increased. 1 and the airflow flowing between the recording medium 3.

[0053] And, it is also possible to Figure 8 As shown in (b), the groove is filled in the portion supporting the attachment portion 14 on the upper portion of the partition plate 17 .

no. 3 approach

[0055] Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. In addition, since the basic structure of this embodiment is the same as that of 1st Embodiment, only a characteristic structure is demonstrated below.

[0056] Figure 9 It is a perspective view showing the carriage and the head cartridge in this embodiment. use Figure 9 The width of the cutout 16 in this embodiment will be described. When the width of the slit 16 is defined as width L and the width of the discharge port row of the first head cartridge 12 is defined as width C, the relationship between the width L of the slit 16 and the width C of the discharge port row satisfies the following formula (3 ), the effect was confirmed by simulation.

[0057] Formula (3) 0.07C(mm)≤L≤1.1C(mm)

[0058] Figure 10 It is a graph showing the simulation result of the inflow air flow rate when changing the width L of the slit 16 in this embodiment. Figure 10 The ver...

Abstract

Provided is a recording device capable of performing recording of high image quality. For this purpose, a separator plate is arranged between head boxes carried on a carriage, flow paths of airflow flowing during scanning are formed at two sides of the separator plate, and a cut is formed on an installation part (14) at an upper part of the separator plate.

Description

technical field [0001] The present invention relates to a recording device that performs recording by discharging liquid to a recording medium. Background technique [0002] In order to perform high-speed recording using a recording device that performs recording by discharging liquid from a recording head, it is necessary to increase the moving speed of the recording head. At this time, fine dust mainly from the recording medium (hereinafter referred to as paper dust) existing on the surface of the recording medium is raised due to the turbulence of the air flow between the recording media, and sometimes adheres to the surface of the recording head to block the discharge port. [0003] In addition, it may adhere to rollers for conveying recording media. When paper dust or the like clogs the discharge port, the image quality may be impaired due to a pattern of white streaks remaining on the recording medium. Furthermore, if it adheres to the recording medium conveyance rol...
