Embodiment Construction

[0023] An ink jet printer (hereinafter referred to as a printer) 1 to which the present invention is applied will be described in detail below with reference to the accompanying drawings.

[0024] As shown in FIG. 1, the printer 1 is a line printer in which ink discharge ports (nozzles) 7 are provided in the width direction of a rolled recording sheet 5, that is, the direction indicated by arrow W in FIG. The nozzles 7 are arranged in approximately parallel rows corresponding to the respective colors. The printer 1 includes a head cartridge 3 and a device main body 4 detachably coupled to the head cartridge 3 . The ink cartridge 2 has ink tanks of yellow (Y), magenta (M), cyan (C), and black (K), and is coupled to the head cartridge 3 . The head cartridge 3 discharges ink.

[0025] The head cartridge 3 of the printer 1 is coupled with and fixed to the device main body 4 . The head cartridge 3 has a heating resistor that heats the ink supplied from the coupled color ink tank...

Abstract

A liquid discharging device includes a line head having a plurality of discharge ports for discharging liquid, the discharge ports being arranged substantially in lines in a discharge surface; a head cap facing the line head, for closing the discharge ports; and a lift mechanism for lifting or lowering the head cap. The head cap closes the discharge ports by being lifted with the lift mechanism substantially perpendicularly to the discharge surface. Also, the head cap comes away from the discharge surface by being lowered with the lift mechanism substantially perpendicularly to the discharge surface to allow a recording medium to be carried between the head cap and the discharge surface.

Description

technical field [0001] The present invention relates to a liquid discharge device having a hood that closes and protects discharge ports of a line head in which discharge ports for discharging liquid are arranged substantially in a row. Background technique [0002] An inkjet printer (hereinafter referred to as a printer) prints images and characters by discharging ink from an ink discharge head onto a recording sheet. Inkjet printers have advantages of reduced operating costs, device miniaturization, and ease of color image printing. [0003] In such a printer, ink is supplied from an ink tank to an ink chamber of an ink discharge head. The ink chamber includes a pressure generating element such as a heating resistor or a piezoelectric element. Pressure is applied to the ink in the ink chamber by the pressure generating element, and the ink is discharged from the fine discharge port, ie, the nozzle, in the form of droplets. The discharged ink droplets land on a recording...
