Device for automatically threading a recording medium into the discharge table of a recording device

The invention relates to a device for automatically threading a recording medium into an exactly defined one Position on the leading edge of the discharge table of a recording device, with drive rollers and associated counter-pressure rollers for the recording medium in the plane of the delivery table.

For certain purposes of recording devices with moving It is desirable for the recording medium not to be placed on a continuous recording medium running off a roll of paper, but rather to record signal curves on individual registration sections. Such registration sections are said to be preprinted Forms are described and added to the documentation after registration. Often should also be on already described form sections at certain time intervals further curves are registered to significant changes to be determined in the measured values. For such registration tasks it is now important to use the individual registration section in the Way to position on the discharge table of the registration device that the registration process is defined and reproducible begins at a desired starting point. During the recording process, the registration section must be exactly parallel to the Leading edge run, as this defines the zero line. the

known run-off tables of recording devices have so-called leading edges on the sides; however, experience shows that it prepares Difficulty in precisely positioning a single recording section. This has to be laborious in each case be done by hand.

The invention is therefore based on the object for a recording device to create a device with a moving recording medium, with which the recording medium in the simplest Way is brought into an exact position on the discharge table and guided during the registration process.

This object is achieved in that the axes of drive rollers and associated counter-pressure rollers enclose an angle I so that when the pressure roller and counter-pressure I roll a force component acts in the direction of the leading edgeJ Preferably there is only one drive roller and associated equipment Back pressure roller present, which is arranged near the leading edge i. The force component with such an asymmetrical approach!

Procedure effected after a few centimeters of the ^run: the recording medium, that the recording medium precisely positioned at the leading edge is located and continues along the guiding edge.

In the figures, 1 is the paper discharge table of a recording device designated. The paper discharge table. 1 is common slightly wider than the width of the paper to be used and instructs so-called leading edges 2 and 3 on the opposite sides. A drive roller 4 is now arranged with its axis of rotation I, that the lateral surface of the drive roller 4 exactly in the

Level of the discharge table 1 runs, · Corresponding to this - mostly slightly resilient - a counter-pressure roller 5 is arranged above the discharge table. Between drive roller 4 and counter pressure roller 5 the recording medium 6 is moved. As a recording medium for the special purpose DIN A4 sheets preprinted in the form used.

From Figure 2 it can now be seen that the axis I of the drive roller 4 and the axis II of the counterpressure roller 5 are tilted against one another and enclose an angle of about 2 ° with one another. Furthermore, there is only one drive roller and an associated one Counter-pressure rollers are present, which are close to the effective leading edge 2. Such an asymmetrical arrangement j tion of drive roller 4 and counter-pressure roller 5 is effective when running; of the drive a small force component in the direction of the Leading edge 2. A sheet of paper is inserted in such a way that the sheet 6 is usually between with one hand Drive roller 4 and counter-pressure roller 5 is inserted. Due to the effective force component in the direction of the leading edge 2 is now already after a short paper run 'the initially - according to FIG. 2 - obliquely inserted sheet of paper 6 with its Long side exactly against the leading edge 2.

By changing the angle between axes 1 and 2 or by moving the drive roller 4 and counter-pressure roller 5 Their axes I and II can now be adjusted to a force exactly at which a sheet of paper 6 is positioned exactly, but is not bent up against the leading edge 2.
