Abstract

The invention relates to instrumentation and can be used to create information data banks. In order to increase the reliability of the device while simplifying its design, the unit for selecting and transporting the disk 2 with the disk pickup unit is mounted movably relative to the disk drive 1. The disk gripping unit in the form of a direct lever 23 uses the elements of rotation 24 to roll the disk from the accumulator into the receiving frame 11, which is installed with the possibility of fixed rotation around the axis of its tail, which makes it possible to install disk 2 on the spindle of the information reproduction unit and transfer the disk for processing his other side. 1 hp f-ly, 2 ill.

Description

The invention relates to instrumentation and can be used to create information data banks.

The purpose of the invention is to increase the reliability of the device while simplifying its design.

FIG. 1 shows a general view of the device ;, FIG. 2 is a section A-A in FIG. one.

The device contains a drive 1 of disks 2 (Fig. 1, 2), the case 3 of the mechanism of the unit for selecting and transporting disks with drives 4 and 5, screws 6 and 7, shafts 8 and 9, sleeve 10, receiving frame 11, removable stop 12, removable movable latch 13, worm 14 and gear 15 wheels, rack 16, worm wheel 17, drive roller 18, infinite flexible element 19 (steel tape), friction spring - clutch

20, rollers 21 and 22, movable lever 23, two rotational elements 24 (rollers) for gripping a disk, a rotational element 25 (roller), a guide 26, rollers 27, and a pin 28 of an information reproduction unit.

The device works as follows

The actuator 4 (FIG. 2) is turned on, the rotation from which is transmitted through the worm to the 6 and the worm gear 14 to the shaft 8 and the gear wheel 15. Rolling on the rack 16, the gear wheel 15 raises or lowers the housing 3 of the mechanism of the selection unit and transporting the disks 2 together with the receiving frame 11 to the storage cell 1 of the disk 2 of the disks 2 (Fig. 1).

Then, the actuator 5 is turned on. At this time, the movable clamp 13 is in the body of the receiving frame 11 and does not allow it to rotate.

By overcoming the force of the friction spring 20, the rotation of the drive 5 through the screw to 7 and the worm gear 17 is transmitted to the shaft 9, and through it to the driving roller 18 and then to the endless flexible element 19 (ribbon) with which the lever 23 is rigidly connected to grab the disc. At this time, the lever 23 from position I moves to position II (FIG. 2) and with its two rollers 24 touches the side surface of the disk 2 on both sides of the diameter, and the roller 25 comes into contact with the guide surface of the receiving frame 11. Thus occurs poking the disk out of disk drive 1 and rolling it into the receiving frame 11 to the position of lever III (Fig. 2), when the axis of rotation of the disk 2 coincides with the axis of rotation of the pin 28. The disk 2 rolls out of the receiving frame 11 into the disk 1 of disks in reverse back when reversed drive 5 .

The rotation of the receiving frame 11 for working with another information disc side is as follows. An electromagnet (not shown) of the movable latch 13 is triggered, which unlocks the receiving frame 11. The actuator 5 is activated; rotation from the shaft 9 through the friction spring 20 is transmitted to the sleeve 10 rigidly coupled to the receiving frame 11. The receiving frame 11 rotates with the disk 2 at an angle to the fixed stop 12, and then the frame is locked with a movable latch 13.
