Description

The invention relates to photo kinotekhnike and can be used in the apparatus for optical recording of information on aerial film.

The purpose of the invention is to improve the accuracy of fixing the coil and ease of charging.

FIG. 1 shows the proposed cassette, longitudinal section; FIG. 2 is a section A-A in FIG. 1,

The housing 1 is made with a hole closed by a l-shaped krppka 2 mounted on the loop 3. Along the contour of the kryshka 2 there is a light labyrinth projection

Shaft 4 is mounted in case 1, on which support sleeve 5 with lead 6 and coupling half 7 are fixed. Coaxially to shaft 4 from opposite CTQ of housing 1 there is a shaft 8 mounted on glass 9. At one end of shaft 8 there is a fixed sleeve 1.0 sec. the leash 11 and the spring 12a at the other end are rigidly fixed to the handle 13, the Glass 9 is mounted in the housing I with the possibility of axial movement and provided with an abutment 14, On the outer surface of the glass 9 there are two triangular grooves mated to the spring lock 15, and a rectangular groove 16 cm in contact with the protrusion 17 krppki 2 in its closed position. A spring 18 is attached to the finger 16. A coil 19 is installed on the shafts 4 and 8 between the sleeves 5 and 10. The light-tight channel 20 with guide rollers 21 is placed in the housing .1,

The cassette works as follows

 charging the cassette with an unobstructed aerofilm wound on a reel, open the lid 2, turning it on the loop 3 relative to the housing 1, and the finger 16, under the action of the spring 18, comes out of the rectangular slot of the glass 9, using the handle 13 moves the glass 9 into axial direction until the abutment 14 contacts the body 1. The spring retainer 15 mates with another triangular groove of the cup 9. Insert the coil 19 with aerofilm through the hole of the body 1 and put it on the shaft 4 with a central hole to yjiopain the support sleeve 5 so that one of the holes on the end

coil 19 was articulated with a leash 6,

The cup 9 is moved with the handle 13 in the axial direction so that the shaft 8 fits into the central hole at the opposite end of the coil 19, and the lead G1 of the fixing sleeve 10 goes into one of the holes at this end of the coil 19. In this position the cup is fixed with a spring lock 15, and the gap between the coil 19 and the bearing bushes 5 and 10 is selected by the pin 12. Pass the end of the aerophotograph from the cassette through the light-tight channel 20 around the rollers 21, Close the cover 2, turning it on the loop 3, while the protrusion 17 moves the pin 16, which one fit into a square groove

9, preventing its axial movement. A cassette loaded with unexposed aerofoil tape is inserted into a tape drive mechanism,

When the cassette is charged with an aerial film coming from a tape drive mechanism, the lid 2 is opened and the coil 19 (without film) is installed as described. Pass the end of the aerofoil inside the housing 1 through the light-tight channel 20 and fix it on the reel 19. Rotate the handle 13 to choose a loop from the film in the tape mechanism and close the lid 2,

The rotation of the coil 19 is carried out using the coupling half 7, mating with the drive mechanism, through the shaft 4, Simultaneously with the rotation of the coil 19

the shaft 8 rotates with the handle 13.

The rotation of the handle 13 in the process of unwinding or winding a roll of aerial film provides visual control over these processes.

The presence of the cup 9, which has two fixed positions, and one L-shaped cap 2 increases the convenience of charging the cassette with aerial film,

.

In addition, the finger 16 provides a lock, i.e. Krshku 2 can not be closed if the glass 9 is not placed in its original position.
