すようにしたことを特徴とするプリンタ。[Claims for Utility Model Registration] Frames 1 and 2 made of synthetic resin, a platen 5 having a rotating shaft 5a made of metal and an outer periphery made of an elastic material 5b such as rubber, and a printing head disposed opposite to the platen 5. 10, and a drive motor 25 for driving the movement of the print head 10. When the drive motor 25 is driven, the print head 10 is moved to the platen 5.
In a printer that prints on printing paper on a platen 5 by moving in the longitudinal direction of the frame, a metal substrate 22 is fixed on the frames 1 and 2, and a drive mechanism rod including the drive motor 25 is moved to the metal substrate. The base end of a metal contact plate 36 supported on 22 and whose tip elastically contacts a part of the rotating shaft 5a is connected and fixed to the metal substrate 22, and the metal substrate 22 is electrically connected to the ground terminal 74. The static electricity generated on the platen 5 is transferred to the metal contact plate 36.
and a printer characterized in that the air is allowed to escape to a ground terminal 74 via the metal substrate 22.
