Description

  The present invention relates to a housing structure in which a suspended matter generating part is built in and a cavity is formed on one surface side of the suspended matter generating part, and a recording apparatus and an electronic apparatus provided with the housing structure.

  An ink jet recording apparatus, which is one of electronic apparatuses, is configured to record ink by ejecting ink droplets from nozzle openings provided in the recording head while moving a carriage on which the recording head is mounted. However, clogging is likely to occur at nozzle openings where ink droplet ejection is small due to an increase in ink viscosity due to evaporation of the ink solvent. Therefore, clogging is prevented by executing a flushing process in which ink droplets are periodically ejected from all nozzle openings toward the waste ink absorbing material.

  By the way, since the particle size of ink droplets has become smaller with the recent increase in image quality, some of the ink droplets may be misted and floated by air resistance before reaching the waste ink absorber. The floating ink mist is also blown and scattered by the air flow accompanying the movement of the carriage, wraps around the back side of the carriage, adheres to the linear scale of the linear encoder for carriage movement control, and becomes contaminated. There is a risk. The ink mist is generated not only in the flushing process but also in a recording apparatus capable of so-called borderless printing.

  Therefore, an ink jet recording apparatus has been proposed in which an air flow restriction means is provided on the carriage. The air flow restricting means regulates the air flow guide working surface that guides the air flow on the side of the carriage to the rear side of the carriage, the upward flow of the air flow guided to the rear side of the carriage, and the flow of the air flow. And a regulating rib for directing in the main scanning direction. Thereby, the flow of the ink mist which goes around the carriage back surface can be regulated, and the ink mist can be prevented from adhering to the linear scale (see Patent Document 1).

Without spreading, it is possible to prevent diffusion of suspended matter in the cavity.

  In addition, the floating substance intrusion prevention member includes a shielding wall that shields one surface side of the floating substance generation unit over the entire width. Thereby, since the suspended | floating matter collides with a shielding wall and it becomes easy to adhere to a shielding wall, it can block | flow into the cavity part of a suspended | floating matter. Further, the floating substance intrusion prevention member includes a shielding rib that shields a partial cross section of the cavity. As a result, even if the floating material wraps around both sides of the shielding wall, the floating material collides with the shielding rib and easily adheres to the shielding rib, thereby further enhancing the effect of preventing the floating material from entering the cavity. be able to. The cavity is characterized in that a control board is disposed. As a result, it is possible to protect an electrical system that is particularly susceptible to the influence of floating substances.

  As shown in FIGS. 3 and 4, the recording unit 190 includes a carriage 191, a platen 192, a recording head (not shown), a waste ink absorber, and the like. The recording head is supplied with ink of each color from ink cartridges (not shown) of, for example, yellow, magenta, cyan, light magenta, light cyan, and black, which are housed inside the front side of the housing structure 101 so that full color printing is possible. Is done. The recording head mounted on the carriage 191 scanned by a carriage motor (not shown) ejects ink droplets from the nozzle openings to the paper that is nipped and conveyed by the paper feed roller 181 and the driven roller 182 and has no border. Execute print processing. In addition, nozzle openings with low ink droplet ejection tend to become clogged due to an increase in ink viscosity caused by evaporation of the ink solvent. Therefore, the ink droplets are regularly directed toward the waste ink absorber from all nozzle openings. A flushing process for discharging the ink is executed.

  Here, in the recording unit 190, during the flushing process or the borderless printing process, a part of the ink droplets ejected from the recording head is misted and floated by the air resistance before reaching the waste ink absorbing material. There is a case. The floating ink mist is also struck and scattered by the air flow accompanying the movement of the carriage 191, and particularly easily enters the back side of the recording area of the recording unit 190. Therefore, the housing structure 101 of the present embodiment has the following features in order to solve the above problems, and will be further described with reference to the drawings.

  FIG. 5 is a perspective view showing a characteristic portion of the housing structure 101, and FIG. 6 is an enlarged perspective view of the characteristic portion shown in FIG. As shown in FIG. 5, the middle housing 102 has a cavity 193 formed on the back side of the recording area 190 </ b> A of the recording unit 190. The cavity 193 is formed in a groove shape along the recording area 190A of the recording unit 190, and a sub-substrate 173 is disposed inside. As described above, the ink mist floating in the recording unit 190 is blown and scattered by the air flow accompanying the movement of the carriage 191, and enters the cavity 193 on the back side of the recording area 190A of the recording unit 190. There is a risk of adhering to the sub-substrate 173 and causing contamination.

  Therefore, a shielding wall (floating matter intrusion preventing member) 102a for preventing intrusion of ink mist is integrally formed in the middle housing 102 between the recording area 190A of the recording unit 190 and the cavity 193. The shielding wall 102a is formed between the left and right side walls 102b of the middle housing 102, and shields the back side of the recording area 190A of the recording unit 190 over the entire width. Accordingly, the ink mist collides with the shielding wall 102a and easily adheres to the shielding wall 102a, so that the ink mist can be prevented from flowing into the cavity portion 193.

  Further, a shielding rib (floating matter intrusion preventing member) 102 c for preventing ink mist from entering is integrally formed in the middle housing 102 in the hollow portion 193. The shielding rib 102 c is formed between the groove widths of the groove-like cavity 193, and shields a partial cross section of the cavity 193, that is, both sides of the sub-substrate 173. As a result, even if the ink mist goes around both sides of the shielding wall 102a, the ink mist collides with the shielding rib 102c and easily adheres to the shielding rib 102c. The effect can be further enhanced.

  As described above, the shielding wall 102a and the shielding rib 102c do not directly affect the recording unit 190 and prevent the ink mist from flowing into the cavity 193, so that the function of the recording unit 190 is not affected. The ink mist can be prevented from diffusing into the 193, and the sub-substrate 173 that is particularly affected by the ink mist can be protected. In the above-described embodiment, the ink mist is prevented from diffusing. However, not only the ink mist but also a foreign substance such as dust or dust can be prevented if it is a floating substance.

  Any recording apparatus having a housing structure can be applied to, for example, a facsimile apparatus, a copying apparatus, a scanner, and the like. Further, the present invention is not limited to a recording apparatus, and can be applied to a general electronic apparatus having a panel structure.
