(54) DEVICE FOR PHOTOTHERMOPLASTIC RECORDING INFORMATION

The invention relates to instrumentation The device for photothermoplastic recording (FTPD) of information is known, comprising a lens with a frame window, a photo-conductor plate, a thermoplastic carrier (ESRT), a mechanism for transporting a medium with an ESR displacement unit in a plane perpendicular to the optical axis of the lens and contacting ESR with phototopductor plate, power supply, development and reproduction units. The disadvantage of the device is the complexity of the design of the TPN displacement unit of the plane perpendicular to the optical axis of the lens, and the contacting of the ESRD with the photoconductive plate, as well as non-stability when photographing. In addition, the recording of the ax; when the lens is constantly open, and the exposure time is determined by the contact time of the photo semiconductor wafer with the ESR when the power supply is switched on between them. The nepeMeuieiniH TPN mechanism does not provide high accuracy of the extracts (especially at low values), which significantly complicates the work of the operator. The purpose of the invention is to simplify the design and ensure stable shutter speeds when photographing. This is achieved by the fact that the photosemiconductor plate is located on the cortex; an electromagnet located behind a personnel window and electrically connected via a power source to a time relay and a release button. The drawing schematically shows a device for photothermoplastic information recording. The image of the object (not shown in the drawing) through the lens 1 and the ESR 2, moved by the transport mechanism of the carrier 3, is optically connected to the surface of the photo semiconductor plate 4 located on the cortex of the electromagnet 5, electrically connected via a time relay 6 and a power source 7 with the release button 8. Along the carrier behind the personnel window, there are blocks for the manifestation of 9 and the reproduction of Yu. TPL and photoconductive

the plate is electrically connected to the power supply.

In the initial position, the photosemiconductor wafer is pressed from the ESR. Before photographing, focusing is performed, the necessary diaphragm is set and held: - Ki to time relay B, then the shutter release button 8 and the electromagnet S are pressed

A pulse is given, the duration of which is set by the time relay. As a result

: baTe of this photosemiconductor plate fi, located on the cortex of the electromagnet, returns mechanical contact with the ESR 2k on the latter while the power supply is on, electrostatic fs is formed. Image At the end of the pulse, the semiconductor plate moves from the ESR to the initial position, the latter is mixed by one frame and the latent electrostatic image i G formed on the ESRT is also manifested by the aid of the manifestation unit 9; one

The image is reproduced by block 10, and then the next frame is captured.
