Description

Device installation angle adjusting device and printing equipment

Technical Field

The present invention relates to a device mounting angle adjusting device and a printing apparatus using the same.

Background

Ink jet printing is typically accomplished by drop-on-demand or continuous ink jet printing. In drop-on-demand ink-jet printing, droplets are ejected onto a recording medium using a droplet ejector with a pressurizing (e.g., thermal or piezoelectric) actuator. Selectively activating the actuator causes the formation and ejection of a droplet that passes through the space between the printhead and the recording medium and impacts the recording medium. The formation of the printed image is achieved by controlling the formation of each drop as required to print the desired image.

The movement of the recording medium relative to the printhead during drop ejection can be to hold the printhead stationary and advance the recording medium past the printhead as the drops are ejected, or to hold the recording medium stationary and move the printhead. Such a printing configuration is suitable if the array of drop ejectors on the printhead can cover the entire printing area across the width of the recording medium, such a printhead sometimes being referred to as a page-wide printhead. A second type of printer architecture is a carriage printer, in which the drop ejector array of the printhead is smaller than the print area across the width of the recording medium, and the printhead is mounted on a carriage. In a carriage type printer, a recording medium is advanced by a given distance in a medium advance direction and then stopped. While the recording medium is stopped, the printhead, carrying orifices that are ejecting droplets, moves in a carriage scan direction that is substantially perpendicular to the media advance direction. The carriage printing a swath of an image by the print head while traversing the print medium, after which the recording medium is advanced; then the carriage movement direction is reversed; the image is thus formed by printing from swath to swath.

Therefore, for the carriage type printing, it is necessary to maintain the moving direction of the print head perpendicular to the media advancing direction during printing, but the print head is installed behind the carriage and the angle of the print head needs to be finely adjusted.
