Abstract

PROBLEM TO BE SOLVED: To preclude ink from getting over the writing face of a writing head, and also ink from adhering to the ink spouting face of a recording head by setting selectively a head face protection member on the ink spouting face of the recording head, or the reading face of an original reading head. SOLUTION: During recording, a reading head 25 moves to a position opposed to a head protection member 25, and a protection member support body 22 moves upward, so that a head protection member 23 is press-mounted on the reading face of the original reading head 25. After dismounting the head protection member 23 from the reading head 25 so as to be moved onto the protection member support body 22, the protection support body 23 moves downward. Following this, a carrier 2 travels such that the ink supporting face of a recording head comes to a position opposed to the head protection member 23 on the support body 22 moves upward, then the head protection member 23 is dismounted from the protection member support body 22 to thus be put on the ink spouting face of the reading head 1.
