Ink-jet recording device

Abstract

To provide an apparatus conformed to trends in the users' business world by giving antibacterial properties to a good-visibility, good-operability, low-cost and high-reliability apparatus enclosure part for an operation panel when the apparatus of good maintainability is to be provided even if an apparatus interior is divided by function, and an operation panel part to be a display and input part is constructed in a door structure to improve the maintainability. In a means for jetting ink particles from a nozzle body thereby forming ink particles, and in the inkjet recording apparatus of a charge control type which records information by adhering ink particles to an object to be recorded through charging and deflection of the ink particles, there are set a partition plate for dividing the apparatus interior above and below, a door-shaped partition plate for further partitioning the lower space divided by the partition plate, and two upper and lower doors at the apparatus enclosure part. A mounting structure for these plates and doors is devised. Moreover, a cooling fan for evenly and efficiently cooling the apparatus interior, an air inlet and an air outlet are arranged. A used material of an apparatus enclosure component is a special grade one proposable to customers. (C)2004,JPO.

Description

technical field [0001] The present invention relates to a charge control type inkjet recording device, and particularly relates to the structure, composition and material of the entire device body except for a printing head for printing on an object to be recorded. Background technique [0002] In the original inkjet recording device shown in Japanese Patent Laid-Open No. 7-76096, since a partition plate is provided inside the device, and the driving source part of the solenoid valve or the pump is arranged in the space on the back side of the device, the components In the case of repair work such as replacement, it is a structure that is very difficult to inspect. In addition, in other products, although there are also examples in which the internal partition is made into a door shape, all of them have a structure that opens in the same direction as the door on the housing side. When there is a lack of work space around the device, this may be difficult. An example of an i...

Problems solved by technology

[0002] In the original inkjet recording device shown in Japanese Patent Laid-Open No. 7-76096, since a partition plate is provided inside the device, and the driving source part of the solenoid valve or the pump is arranged in the space on the back side of the device, the components In the case of repair work such as replacement, it is a structure that is very difficult to inspect

In addition, in other products, although there are also examples in which the internal partition is made into a door shape, all of them have a structure that opens in the same direction as the door on the housing side. When there is a lack of work space around the device, this may be difficult. Example of an interior door not opening sufficiently for repair work

[0003] In addition, in the conventional inkjet recording apparatus disclosed in the above-mentioned Japanese Patent Laid-Open No. 7-76096, the cooling means in the apparatus adopts the following configuration. In this configuration, a cooling fan is installed to attract outside air and send the air into the control area of ​​the upper space of the device. It can be considered that in this configuration, the flow path of the wind is restricted, resulting in a partial decrease in cooling efficiency.

In addition, as seen in other products, a cooling fan is arranged on the partition inside the upper and lower division devices, and air is sucked from the upper space (control part) and exhausted from the lower space (ink circulation part). If the airtightness of the entire circumference of the partition plate divided up and down cannot be maintained, or the passage to the exhaust port on the downstream side cannot be obstructed, it is considered that there is a disadvantage that the cooling efficiency is greatly reduced.

[0004] Next, when an operation unit for displaying information and inputting information is provided on the front side of the device, it is desirable to face obliquely upwards from the viewpoint of visibility and operability. There are also examples of actual use, but the operation unit does not have a door structure. Example, access to internal components is difficult from the front side of the unit

[0005] In addition, for the material of the external parts of the device, general-purpose stainless steel plates or plastics are used, but grades with enhanced antibacterial specifications are not used in particular.
