Abstract

PURPOSE:To freely change the gazing direction and position of eye point for looking the image of a finder device of a camera, etc., by transmitting the visual field image of the finder device by utilizing an optical fiber. CONSTITUTION:A lens 32 for image formation is provided at the eye point of a finder device 10 in an input adaptor 30 and the visual field image of the finder device 10 is formed on the input-side end face 22 of an optical fiber section 20. The visual field image of the finder device 10 is formed on the input-side end face 22 of the optical fiber section 20 through an eyepiece 12 and the image forming lens 32. The image is transmitted to the output-side end face 24 of the optical fiber section 20 through each optical fiber. Therefore, the operator of this optical device can observe the visual field image of the finder device 10 when he looks the image on the output-side end face 24. Since the optical fiber section 20 can transmit almost all of the rays of light made incident to the input-side end face 22 even if the section 20 is bent in an optional direction at an optional angle, the gazing direction can be changed 180 deg. because of its nature.
