Abstract

The invention relates to a microfilming apparatus and allows for improving the productivity of the apparatus, improving the operating conditions by reducing the height of the apparatus, and reducing energy consumption. The device contains two originators 5 and 6, a means of movement 7 of the original holders, adapted to the mutual exchange of their location. The document holder 5 is located at the base of the apparatus body, and the document holder 6 is located at a greater distance from the base of the body. 1 hp f, 6 Il.

Description

The invention relates to technical microfilm means, to static static imaging devices of large format originals, mainly on electrophotographic non-silver film.

The aim of the invention is to increase the productivity of the apparatus, to improve the operating conditions by reducing its height, reducing the energy intensity.

Figure 1 shows the apparatus, a general view; figure 2 is the same, side view; in FIG. 3, view A in FIG. 2; 6 shows the transportation mechanism in various stages of exchange of the original holders, a section.

The device contains a shooting camera 1, by means of a transitional bracket 2 mounted on a rack 3 on which the illuminators 4 are fixed. In the field of view of the camera and illuminators there is an original holder 5 mounted at the base of the case. The original holder 6 is removed from the field of view of the camera and the illuminators and is located at an ergonomically optimal distance from the base of the housing. Both originals are installed in displacement means 7. The control unit is fixed to the stand of the apparatus with a control panel 8 facing the operator's location at the originator 6. Each originator is provided with a swivel cover 9, made of transparent material. The shooting camera 1 is equipped with a lens 10, and lamps 11 are installed in the illuminators.

The movement means 7 comprises a movable carriage 12 for fastening the originator 5 and a movable carriage 13 for securing the originator 6, the carriages 12 and 13 by means of pairs of rollers 14 and 15 are installed in the guide grooves of the means 7, with (L

than both pairs of rollers of one of the carriages are located in one straight groove 16, and the rollers of the other carriage are positioned so that one pair of rollers is in the straight groove 17, and the other pair is in a curvilinear groove 18. The grooves 16 and 17 are parallel, and the concavity the groove 18 faces the groove 17, and the extreme points of the groove 18 are at the same distance from the groove 17o. The tool 7 is provided with an electromechanical drive 19 with a drum 20 on which a cable 21 is wound, held through the tension roller 22 and attached to the movable carriages 12 and 13.

The device works as follows.

The operator inserts a sheet of film into the pickup unit of camera I (not shown) and turns on the machine. While the machine prepares automatically for the exposure of the operation (picking up a sheet of film, electrifying the film, moving the film to the exposure position), the operator lifts the cover 9 of the original 5 places the original 23, closes the cover 9, and the control 8 starts the movement 7. The electric drive 19 is turned on, the drum 20 starts to rotate in the direction shown by the arrow, and the cable 21 moves the carriages 12 and 13 of the original holder towards each other. In this case, the rollers of the carriage 12 move along one straight-line guide 16, thus providing a plane-parallel movement of the originator 6. The rollers of the carriage 13 move along two guides 17 and 18, the distance between which increases so that the document holder 5 rotates as it moves and in the middle of the path occupies a position parallel to the direction of its movement. Due to this, the original owners dispense with each other and exchange positions as they move further. At the same time, the original holder 6 with the original 23 is in the field of vision of the optical-lighting system. The lamps 11 are turned on and an original placed on the original-containing body 6 is exposed. The operator, in the meantime, lifts the cover 9 of the original

sets the next original and closes the cover.

After the end of the exposure, the operator restarts the moving means, while the drum 20 rotates in the opposite direction and the original holders 5 and 6, moving in the opposite direction, return to their original positions along their trajectories. Simultaneously, a sheet of film in the shooting chamber is moved to the shooting position of the next frame. To shoot the next original, the operator repeats the steps described.

Claims (2)

1. A microfilming apparatus, predominantly electrophotographic, for shooting large format originals, comprising a static-reproduction optical-lighting system, including illuminators and a camera, placed in a housing above the original holder, which is horizontally placed in the optical-optical system, and that, in order to increase productivity, improve operating conditions by reducing the height of the apparatus, reduced energy intensity, the apparatus contains additional lnitelio second platen originapoderzhateley and displacement means adapted to interchange of their location, with one of originapoderzhateley located at the base body, and the other - at a greater distance from the base body, 2. The apparatus according to claim 1, wherein the transport means comprises two original carriage connected by a cable, reversible drive with a cable drum, connected in the guides, and the guides for one carriage made in the form of a rectilinear groove, and the guides for the other carriage are made in the form of two slots, one of which is rectilinear and the other curvilinear, with concavity facing the rectilinear, the extreme points of the curvilinear groove being at the same distance from the rectilinear .
