Title:
データ写し込み装置及びデータ写し込み装置を備えたカメラ
Document Type and Number:
Japanese Patent JP3859195
Kind Code:
B2
Abstract:
In an optical data recording device, an LCD panel, an aperture stop and a projection lens are arranged in this order from the object side, and a center of the LCD panel is displaced from an optical axis (68a) of the projection lens in a direction away from an optical axis (11a) of an taking lens, so an image of data displayed on the LCD panel is projected on a photo filmstrip at a position that is shifted from the projection lens optical axis (68a) toward the taking lens optical axis (11a). Assuming that the focal length of the projection lens is "f", the distance from the aperture stop to the image side surface of the projection lens is "d", the radiuses of curvature of the projection lens on the respective sides are "R1" and "R2", the distance from the LCD panel to the aperture stop is "S", the longer side length of the LCD panel is "L", the shift amount of the center of the LCD panel from the projection lens optical axis is "Q", the f-number of the taking lens is "F1", and the f-number of the projection lens is "F2", the following conditions are satisfied: 1 > d/f >/= 0.3, R1 > R2 x 3, 0 <θ < 0.55 ( θ = TAN<-1> ä(Q + L/2) / Sü), log2 (F2)
