Problems solved by technology

[0005] However, in the method disclosed in Patent Document 1, since it is necessary to detect the force applied in a direction different from the direction on the surface of the medium, and judge the occurrence of floating based on this, it is not only the two sides on the surface of the medium. The calculation of the movement amount in the three-dimensional direction also needs to calculate the movement amount in the three-dimensional direction, so the processing load will increase.

Embodiment Construction

[0035] Embodiments of the present invention will be described below with reference to the drawings.

[0036] figure 1 Shown is an example of printing by the handheld printer 10 . The handheld printer 10 can receive image data from an image data output device such as a smart device or a personal computer (PC: Personal Computer). Next, the hand-held printer 10 can scan freely on the print medium in a planar manner, that is, freehand, based on the image data, to form an image. The printing medium is, for example, a notebook or paper for design.

[0037] The handheld printer 10 detects the position by the navigation sensor 30 and the gyro sensor 17 as described later, and when the handheld printer 10 moves to the target discharge position, it discharges the ink of the color to be discharged at the target discharge position. Since the place where the ink has been ejected is shielded from being the object of ink ejection, the user can form an image by scanning the handheld printe...

Abstract

The present invention relates to a droplet discharge device and a droplet discharge method. To detect floating of a handheld printer with a simple configuration in free hand scanning of the handheld printer. The droplet discharge device which receives thei mage data and performs scan by users to form an image on a medium includes: a head which discharges droplets; a sensor for detecting movement amount of the droplet discharge device during a prescribed period; a discharge control section which performs discharge control for instructing discharge of droplets on the basis of the image data andthe movement amount detected by the sensor; and a determination section which determines floating of the droplet discharge device. The determination section determines floating on the basis of acceleration of the droplet discharge device. The discharge control section stops the discharge control when the determination section determines floating.

Description

[0001] This application was submitted on November 01, 2018, with application number 201811296131.3, and a divisional application of the patent application titled "Droplet Ejection Device and Droplet Ejection Method". technical field [0002] The present invention relates to a droplet ejection device and a droplet ejection method. Background technique [0003] Printers that feed paper and eject ink or the like at a timing when the paper reaches an image forming position to form an image are known. On the other hand, with the miniaturization of notebook computers and popularization of smart devices, there is an increasing demand for miniaturization and portability of printer devices. Thus, miniaturized hand-held printers have gradually become practical by eliminating the paper delivery system from the printer device. Since there is no paper delivery system in the handheld printer, the paper is scanned and the ink is discharged by the movement of a person on the paper. [000...
