Description

Known counting-switching devices, for example, for photo-diagonal machines, equipped with sum. Mm, her gear, the total angle of rotation of which is proportional to the sum of widths of typed characters.

However, these devices are complex in design.

In the described invention, this disadvantage is eliminated by the fact that one gear wheel carries a toothed sector that drives a cam, limiting movement of a lever rigidly connected to a second gear connected by a gear system with a counting disk having several rows of holes through which using electrocontact sensors, the corresponding pulses are applied to the counting trigger device, which actuates the perforator, which reproduces on the perforated tape, encoded as a system rforatsy commands for controlling designations circuit breaker device maschiny typesetting.

To switch the trigger device to receive pulses from a specific electrocontact sensor, a stepping switch is used, controlled by the space key of the photosetting machine.

When typing, the summed gear / is rotated by an angle whose value is proportional to the sum of widths of typed characters, and with a line length close to the given one, the toothed sector 2 engages gear 3, driven by the Arch 4 spiral. The count of the number of space elements is carried out by a step switch 5, the operation of which is controlled by an electromagnet 6, which is triggered by closing the contact 7 of the space bar.

№ 134132-2 -:.

At the end of the row, pressing the button 8 turns on the electric motor 9, the rotational movement of which through the electromagnetic clutch 10 is transmitted to the counting disk // with openings connected through gear 2 with the lever 13. The movement of the lever 13 is limited by the cam 4.

The counting disk // has four rows of holes with different pitch. Depending on the number of space elements, the counting trigger device 14 receives pulses from one of the electrocontact sensors 15, 16, 17, 18 and the angle of deviation of the lever 13 from the line defined by points 19, 2 (/ is measured in various angular measures.

The counting trigger device is made in the form of trigger cells, the load of which are windings 21, 22,23, 24, 25, 26, 27 and 28 relays. At the moment of the interaction of the lever 13 with the cam 4, the relay 29 will disengage the clutch 10 and the coded signal from the counter trigger device will activate a punch (not shown in the drawing), which plays the coded designation of commands on the punched tape to control the switching device of the dialer.
