Title: Reproducing method
Inventor: ENDOU KIYONOBU
IPC: G11B11/105
Filed: 1981-02-27
Abstract: PURPOSE:To prevent mechanical damage, by reducing mechanical friction between a recording tape and a transcription member, through the movement of a magnetooptic transcription member which reads a magnetic pattern in the running speed of a recording medium recorded with a magnetic pattern. CONSTITUTION:A magnetic transcription film is formed on a magnetic pattern transcription cylinder 11 and supported rotatably. A recording tape 3 runs between a cylinder 5 and a transcription cylinder 11 while putting closely together to the both. As mentioned above, the cylinder 11 is abutted to the cylinder 5 via the recording tape 3, and the cylinder 11 is turned conforming with the run of the tape 3 so that the transcription member on the cylinder 11 is moved. Thus, the mechanical friction between the recording tape and the transcription member is decreased and damages due to mechanical friction are avoided.

IPC: G02B7/02
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent failure such as the deviation or the distortion of a lens caused by the expansion of air in a lens chamber formed between the lenses by forming a groove for ventilating between the lens chamber and the outside of the lens barrel on the inner peripheral surface of the lens barrel holding the lens. SOLUTION: The groove 52 in the optical axis direction is formed on the inner peripheral surface of a lens barrel main body 12 where plural lenses 14, 16 and 18 and distance rings 20 and 22 are disposed so as to ventilate between the lens chambers 54 and 56 between the respective lenses and the outside of the main body 12. Thus, when the respective lenses are attached in the main body 12, air resistance is reduced and the lens is easily attached. Even when temperature in the lens chamber rises and the air is expanded by the irradiation of ultraviolet rays in the case of attaching the lens 18 with ultraviolet curing adhesive, the lens does not receive strong pressure and the failure such as the float of the lens is prevented. Even when the air is expanded because of the temperature rise in the lens chamber due to a fire, etc., the deviation or the distortion of the lens is prevented.
