Abstract
In the case of writing information on a writing medium, such as the crown cap of a bottle, by the use of an ink drop writing apparatus, the information cannot be written at one selected position because the height of the writing medium varies with the height of the bottle and due to other factors. In emitting and deflecting charged ink drops to effect a writing on a writing medium whose position may vary somewhat, this invention detects the position of the writing medium in the deflecting direction of the charged ink drops with photoelectric means and increases or decreases the amount of deflection of the ink drops in accordance with the detected position of the writing medium. It is, accordingly, possible to write the desired information at precisely the correct position on the writing medium at all times.
