Abstract

PURPOSE:To use the same projection lens with a copying system by using a long-sized line sensor 21 which is nearly as long as a photosensitive transfer drum is wide corresponding to a branch mirror. CONSTITUTION:A branch mirror 20 is inserted into the path of transmitted light projected on the photosensitive transfer drum 12 in the lengthwise direction of the drum 12, and the long-sized line sensor 21 is arranged along the branch mirror 20 in order to photodetect the reflected light. The branch mirror 20 uses, for example, a half-mirror, etc., and the light reflected by the mirror 11 of the copying system is split into two; when the branch mirror 20 uses the half-mirror, the transmitted light of the mirror 20 is guided to the photosensitive transfer drum 12 and also supplied to the long-sized line sensor 21. Thus, the same projection lens with the copying system is used.

Figure 1 shows a schematic configuration of a microfilm reader/printer. Light from a light source 1 is irradiated onto a microfilm 3 through a conode lens 2, and the light transmitted through the microfilm 3 is transmitted through a projection lens 4. After that, you can get q to Half Nilla-5. Then, the transmitted light from the macro film 3 is transmitted through the half mirror 5 to 2
The light transmitted through the half mirror 5 is projected onto a screen 7 via a mirror 6, and a third image on the microfilm is projected onto the screen 7. Further, the light reflected by the half mirror 5 undergoes image reversal processing via the mirrors 1O and 11, and then is irradiated onto the photosensitive transfer drum 12 for obtaining a hard copy. The image on the microfilm 3 is transferred onto paper P to form a heart copy.

In such a microfilm L1 reader/printer, when an image on the microfilm 3 is to be electronically transmitted, conventionally, the enlarged image from the 71' black film 3 is transferred to a CCD.
(Charge Coupled Device), etc., and form an enlarged image of the microfil 1 on the line sensor 1- which performs this electric transmission function, and from this tin sensor. The sub-scanning is performed by timing the signal readout, and the main scanning is performed by moving the line sensor itself. For this reason, when a tin sensor is installed in a micro film printer, a dedicated optical system separate from the coher system or the projection system lens for the screen system is required, and the micro When used, separate lens systems are required for the copy system or screen system and the transmission system.
However, the disadvantages are that the number of lenses required or the type of magnification of the microfilm must be multiplied, which leads to complicated equipment and an unavoidable increase in price.

This invention adds an electrical transmission function to a microfilm reader 1 printer as shown in FIG. 1, and a photosensitive transfer drum 1 as shown in FIG.
A distribution mirror 20 is inserted along the long hair direction of the photosensitive transfer drum 12 in the path of the transmitted light projected onto the photosensitive transfer drum 2, and the distribution mirror 20 is arranged to receive the reflected light from the distribution mirror 20. A long line sensor 21 made of an amorphous silicon sensor or the like is arranged along the line 20.

The distribution mirror 20 is a movable mirror or a half mirror, and divides the light reflected from the mirror 11 of the copying system into two parts.For example, when the distribution mirror 20 is configured with a half mirror, the mirror 20 The transmitted light is given to the photosensitive transfer drum 12, and the reflected light of the mirror 20 is also received by the long line sensor 21 arranged in the direction of the photosensitive transfer drum 12. Further, when the distribution mirror 20 is composed of a movable mirror, by vibrating or rotating the distribution mirror 20 about its longitudinal axis, the reflected light from the mirror 11 is transferred to the photosensitive transfer drum 12. The reflected light is then applied to the long line sensor 21, and reflected light is then alternately irradiated between the photosensitive transfer drum 12 and the long line 21.
