SU387398A1 - THE DEVICE OF MOVEMENT OF READING HEADS - Google Patents

Description

one

The invention relates to computing and can be used for the positional movement of a read head assembly.

Devices for moving reading heads are known, which contain a rocker mechanism, in the slider slot of which the finger of the crosshead is mounted, which is installed on the output shaft of the drive coupling.

However, the known devices have insufficient speed.

The aim of the invention is to increase speed and the implementation of the adjustment of the stroke of the slide.

For this purpose, the yoke finger, mounted in its guide slots, is connected to a control electromagnet located under the crosshead, and the crosshead contains fingers, each of which is associated with a corresponding groove on the slider by a corresponding control electromagnet.

The drawing shows the design of the proposed device. It contains a slider / with guide grooves and a block 2 of reading heads mounted on it, moving along guide 3. Traverse 4 contains a series of fingers 5 with rollers 6 and pins 7. Under the action of springs 8, the fingers are in the initial position, in which their rollers are derived from the slots of the slide 1. Under

The traverse 4 beside each finger 5 has a control electromagnet 9. When a predetermined control electromagnet 9 is triggered, the corresponding finger 5 with a roller 6 is inserted into its slider slot /. This position is fixed by the strap 10, which is pressed against the pins 7 of the fingers 5 by the spring 11. The cross member 4 is fixed on the shaft 12, which is driven by the motor 13 through the coupling 14 half a turn.

The motor 13 rotates continuously. When the clutch 14 is turned on, the shaft 12 with the crosspiece 4 is rotated half a turn and the roller 6

A finger 5 inserted into the groove of the slider 1, rotated around the axis of the shaft 12, will move the slider / along the sling 3 by a specified distance in the selected direction and, therefore, the block 2 of the heads.

At a constant number of revolutions of the motor 13, the slider / moves in a sinusoidal manner. The amount of movement of the slide / is equal to double eccentricity between the axis of the finger 5, inserted into the groove of the slide 1, and the axis of the shaft 12.

When any of the control electromagits 9 is triggered, the bar 10 will shift and any finger that was previously engaged with the slider 1 will return to its original position under the action of the springs 8 than the simultaneous engagement with the slider / only one palp 5 of the traverse 4.

The subject is invented and

1. A device for displacing reading heads, which contains a rocker mechanism, in the slot of which is located a finger of a crosshead mounted on the output shaft of the drive coupling, characterized in that

In order to increase the speed of the device, the traverse finger, mounted in its guide slots, is connected with a control electromagnet located under the traverse. 2. A device according to claim 1, characterized in that, in order to control the magnitude of the stroke of the slide, the crosshead contains fingers, each of which is associated with a corresponding groove on the slide and a corresponding control electromagnet.
