Printer apparatus

Abstract

The printer apparatus (10) is structured so that ink is ejected to perform printing on a plate-like medium (B) while a printer head (32) is moved in the right and left direction in a state that the printer head (32) is faced to the plate-like medium (B) supported by the platen (13). The printer apparatus (10) is provided with a front and rear drive motor, which rotationally drives a feed roller (21) in a state that the plate-like medium (B) is pinched by the feed roller (21) and a pinch roller (24) which are paired to feed the plate-like medium (B) to the front side and to set to be located on the platen (13), a right and left drive motor which moves the printer head (32) in the right and left direction, and a controller which performs control for feeding the plate-like medium (B) and control for moving the printer head by the right and left drive motor (32). The platen (13) is provided with a feeding auxiliary member (40) which is protruded from a support face for supporting the plate-like medium (B) and is located on the front side with respect to a portion facing the printer head (32).

Description

technical field [0001] The invention relates to a printing device which prints on a printing medium by ejecting ink from a printing head. More specifically, the present invention relates to a printing device capable of printing on a plate-shaped printing medium. Background technique [0002] Conventionally, there is known a printing device (inkjet printer) that combines a sheet-like printing medium (hereinafter referred to as a sheet-like medium) with respect to a platen (platen). Printing is performed on the printing medium by the control of forward and backward feed and the control of ejecting ink while moving the print head facing the platen left and right. In recent years, there has been a demand for printing on sheet-shaped media and plate-shaped printing media (hereinafter referred to as plate-shaped media) using such printing devices. In order to meet this requirement, for example, a configuration is known in which supporting members for horizontally supporting a pl...

Problems solved by technology

When using the patent document 1 image 3 When printing such a large plate-shaped medium with the configuration shown, since the contact area between the plate-shaped medium and the platen 10 is large, the sliding resistance between the upper surface of the platen 10 and the lower surface of the plate-shaped medium become larger, sometimes placing an excessive burden on the feed roller 15

In this way, if an excessive load is placed on the feed roller 15, for example, the contact portion between the feed roller 15 and the plate-shaped medium is likely to slip, and it is difficult to feed the plate-shaped medium forward and backward with high accuracy while ensuring positional accuracy. May degrade printing quality
