Claims

[Claims for Utility Model Registration] (1) A doctor whose sharp tip is supplied with printing ink, and a plurality of annular grooves are provided on the outer circumferential surface of the doctor, which contact the tip of the doctor. a receiving roller that rotates to deposit the ink in the annular groove, and is spaced apart from the receiving roller;
A horizontal kneading roller that reciprocates in the axial direction while rotating, is interposed between the receiving roller and the horizontal kneading roller, contacts both of them alternately while rotating, and transfers the ink adhered on the receiving roller to the horizontal kneading roller. A replacement roller, an inking roller that rotates in contact with the horizontal kneading roller to transfer and knead the ink, and a marking body is provided on the outer circumference, and an inking roller that rotates in contact with the inking roller to transfer and knead the ink; A marking device comprising a marking roller to which ink is attached, and an offset roller that rotates in contact with the marking roller, transfers the ink printing, and marks a printed object that is moved downward. (2) The marking device according to claim 1, wherein the object to be printed is a semiconductor device package. (3) The marking according to claim 1 of the utility model registration claim, characterized in that the object to be printed consists of a plurality of semiconductor device packages attached to a lead frame and in a state before being separated, and the markings are made simultaneously. Device. (4) Claim 1 of the utility model registration, which is characterized in that the time during which the transfer roller contacts the receiving roller and the horizontal kneading roller can be adjusted as required.
The marking device according to any one of Items 1 to 3.
