クロフイルムリーダ。[Claims for Utility Model Registration] (1) The microfilm in the memory cassette set in the main body is fed out, a predetermined frame is stopped at the projection position, and the frame is pressed with a pressing frame to display the image part of the frame on the screen. A cylindrical abrasive material is rotatably provided on the pressing frame so that its axis is perpendicular to the microfilm feeding direction and its peripheral surface is in pressure contact with the microfilm; A microfilm reader characterized by being provided with a drive motor that rotates the abrasive material to scrape off the image of a predetermined frame when the microfilm is sent out while the pressing frame is pressing the frame of the microfilm. . (2) Feed out the microfilm in the cassette set in the main body, read the image information recorded on the magnetic tape part of the microfilm with the magnetic head, and create an image of a predetermined frame based on the read image information. In a micro-microfilm reader that projects images onto a screen, a cylindrical abrasive is rotatably attached to the magnetic head so that its axis is perpendicular to the microfilm feeding direction and its peripheral surface is in pressure contact with the microfilm. A drive motor is provided which is detachably installed and rotates the abrasive material to scrape off the image of a predetermined frame when the microfilm is sent out while the magnetic head is in contact with the microfilm. Microfilm reader.
