Abstract

PURPOSE:To monitor main information and imprinting data with a single display by providing a reflecting means in an optical path and permitting the data information on the display to be seen through the reflecting means from the outside of the device. CONSTITUTION:Reflecting mirrors 27 and 28 are placed in the optical path including a transmission type crystalline plate 23 and an image forming lens 25; the mirror 28 is swingably held so that it can move outside of the optical path from its inside. In imprinting data, the data information which has been set is displayed on the crystalline plate 23, and imprinted on the reflecting mirror 28 after it is reflected by the reflecting mirror 27; therefore, the image reflected on the mirror 28 can be seen through a monitoring display window 4d from the outside of the device. When it is imprinted on a film F, the mirror 28 moves outside of the optical path where data is imprinted. A shutter 26 opens, and then the data information displayed on the crystalline plate 23 is recorded onto the surface of the film F after it is reflected by the mirror 27. Thus, it is not necessary to provide an extra display for monitoring and cost is also reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a photographing device that photographs and records image information, data information, etc. on a film using an optical system.

<Prior Art> Conventionally, a rotary camera is known as a typical example of this type of photographing device.

This rotary camera sequentially captures and records image information of materials to be processed into microfilm for preservation on a long film, and is capable of rapid, large-volume photography. In addition to imprinting the main information on the film, you can also imprint necessary secondary information such as shooting date and time, serial number, top title, subtitle, end title, search mark, etc.! (below,
(referred to as "data imprinting") is performed whenever necessary. Burnt-like data imprinting 4 Searching for photographic information for each unit of photographing date or classification unit, division between frame groups, and required photographic information portions that are continuously imprinted on a long film.

This is necessary to facilitate editing processing, etc.
