Title:
HIGH-SPEED AND MULTI-MAGNIFICATION PHOTOGRAPH FINISHING DEVICE
Document Type and Number:
Japanese Patent JP2763733
Kind Code:
B2
Abstract:
PURPOSE: To selectively and alternatively project a luminous flux carrying an image with any magnification by quickly and accurately controlling a magnification lens of an optical system to its proper position.
CONSTITUTION: A high-speed and multi-magnification photograph finishing device which projects an image on a projection face including photographic paper with different magnifications is provided with a means which carries a photographic negative 12 carrying the image, a means which cooperates with the photographic negative 12 to form an image carrying luminous flux, and plural lenses 20, 22, and 24 which are arranged apart from one another. Lenses 20, 22, and 24 project the image on photographic paper 16 placed on the projection face with different magnifications. The photograph finishing device is provided with a luminous flux position change means, which selectively guides the image carrying luminous flux to photographic paper 16 through one of magnification lenses 20, 22, and 24, to selectively and alternatively project the image carrying luminous flux on photographic paper with different magnifications. The luminous flux position change means is constituted as an array of flat mirrors, and this array is fixed and attached to a movable carriage with a proper method.
