Depending on the excitation from one or the other switch 2 or 8, this changeover switch 5 produces a .drregungsweg to an actuating magnet 10, on which a clutch 11, a so-called booster clutch, is engaged for a certain time of the device and forwards this drive movement, on the one hand, to the clutch 11 and, on the other hand, in a ρ-parallel line via a gear train 13 to a further clutch 14. The latter clutch, which is switched on according to aspects still to be determined, leads the drive to a tow coupling I ;? further, which has a certain idle and the pulling device 6 drives. The clutch 11, on the other hand, has a mechanical drive connection 16 to a so-called switching roller impulse 17 for the copy paper drive, and this conveys the copy paper further in ei-η. Conveyor device 18 for the copy paper · This conveyor device 18 is, for example, a combination of drive rollers and belts in a copier, which are driven via a * mechanical gear train 19 via the main drive 12. .

An essential feature of the invention is that between the booster control clutch 11 and the switch 5 a mechanical richalt connection 20 is arranged, which selectively switches the switch back and forth,

It can be seen that the ochaltv / e ^ e 2M, 22 work electrically,

the stop paths 23, 24, 25, 26 can be operated mechanically. This means that the present invention is based on a drive which can be actuated electrically by two branches, namely from the switches 2 and forth, but can be actuated mechanically by a main drive 12 with the engagement of a tow coupling 15 in series with several couplings, with a mechanical gear engagement fc 20 reacts in the electrical circuit in order to bring about the necessary switchings that guarantee the reliable function but despite the drive from the same main drive 12 ^r "in the drive chain between the two '!' rush the tow coupling 15 is arranged o This tow coupling is intended not only to compensate for the difference in the advance speed, but at the same time to ensure that an ex lapping between copy sheets, which are conveyed by "the withdrawal device, is prevented by the conveying device 18 withdrawing the engaged copy sheet faster than the next following one is subsequently conveyed by the extracting device 6.

In this, like parts are designated by like reference numerals ο In particular aaszugehen the fact that the s / ege of the copy paper, the pull-out device 6 is provided which comprises a roller 26 which ut on the top of a -sheet ■ 'apeIs located. The axis 27 of this roller is mounted in a swivel bracket 28, which can be rotated about a shaft 29, which at the same time drives a continuously rotating feed roller 30, which is assigned to a so-called switching roller 31 in front of the stack, on the topmost sheet of which the sheet 26 lies. The shaft 29 goes to a drive wheel 32 through a frame wall 33. The drive wheel 32 is constantly driven in a manner not shown in detail. The tichalt roller 31 sits on a shaft 34 »cLie with regard to tfig. 2 is located under the rtelle 29 and carries a clutch wheel 35 iß non-rotatable arrangement. Its function will be explained in more detail.

On the through shaft 29 sit non-rotatably a gear 36 which meshes with a coupling gear 37, and an assembly auü the gears 38, 39, which are connected by a bushing 40 and rotatably arranged on the shaft 29, the gear 38 meshes with a ring gear on the coupling half 41 of the coupling 37 »41» the in i'ig. 1 is denoted by 14.

In connection with the coupling half 41, an actuating lever 43 is provided which is fixedly mounted on a shifting clutch half 44, the interlocking clutch half 45 of which is arranged on a wheel 46 which, according to FIG. 3, has two circumferential recesses 47, 98, in which a drive wheel 48 rotates, which is non-rotatably arranged with the coupling gear 37 on the shaft 49 "The coupling halves 44, 45 each have a step 50, 51" These steps are offset from one another in the starting position. These steps are followed by the inclined surfaces, one of which ^{is designated 52 in E 1} Ig ₀ 2 - the meaning of these surfaces will be explained below, but it is pointed out that the coupling shanks 44 below the action of a spring 53, which on the other hand is supported on a frame wall 54. The corresponding associated frame wall 55 is shown in FIG. 2. The frame walls are used to store the parts. The spring 53 presses the coupling half 44 towards the coupling half 45, whereby the stepped surfaces, when engaged by the spring 53, allow an axial movement of the coupling half and thus a pivoting movement of the lever 43 about its pivot pin 56 for the engagement of the coupling 41, 37 It is noted at this point that the parts 46, 48 forming a coupling in connection with the parts 65, 70 assigned to them to be described correspond to the coupling 11 in FIG. alzen 30, 31 of the coupling 17 in FIG. By moving the lever 43, the actuating member 57 of a switch 58, which corresponds to the switch 5 in FIG. 1, is moved at the same time. Depending on the movement of the coupling 46, 48, the switch 58 is therefore also reversed

üs is further pointed out that an anchor 59 is one with reference to Pig "1 to the actuating magnet 10, which corresponds to the magnet designated by corresponding reference numerals in FIGS _o 2 and 3, the magnet against the action of a spring 60 movable is. The armature actuates a two-armed pivot lever 61. This is arranged pivotably on a bearing column 62 which is fastened in the frame wall 55. The lever 61 has an engagement projection 63 at its free end, which engages with a step 64 · a locking disk 65 on the had 46. The hasty disk 65 has a further latching step 66 diagonally opposite, so that after a single brief release one rotation only comes through 180 °. Then the Ümfangsausnehinung 98 is in front of the drive wheel 48. It is also pointed out that the locking disc 65 is provided with pins 67, 68 and in the not shown -,. ,, presented frame a leaf spring 69 is arranged, which by means of

j the stops 67 »68 presses the washer into engagement with the drive W r ^ ad 44 when a release takes place, v / furthermore, the cam 70 is provided on the hasty disk 65 with the cam 71 with the one end of a pivot lever 99 is engaged. The pivot pin 72 of this pivot lever is located between the locking disc 65 and a stepped notch 73 on the coupling wheel 35. This coupling wheel sits on the shaft 34 with the shift drum 31 under the cattle 29, as can be seen from FIG.

In terms of function, it should be noted that when the magnet 10 in FIG. 1 is actuated, the coupling wheel 4-6 revolves by half a turn, thereby closing the coupling 41, 7 or 14 and switching the switch 58 or 5 over. As a result, however, the copy paper is initially required, with the nut-like ring 81 migrating axially. If the copy paper then hits the container, the toggle two of the Üchalter S, which was previously switched

has been switched to conduct one pulse to another Excitation of the magnet 10 is used, so that the disc 46 again rotates 180 °, the disk or vfalze 35 then locked becomes and comes to a standstill. This is an accurate Control guaranteed

It should also be noted that the coupling with of the wandering Isiutter 81 an overlap of successive ones Paper is avoided «, the stop 83 is advantageously so low-friction executed as possible

According to FIGS. 6 and 7, the coupling with the 'files 44, 45 is particularly shown. Between these coupling parts there is a step 84, 85 and an inclined surface 86, 87 arranged behind the step, if necessary at a distance, the steps are denoted in FIG. 2 with 50, 51 and the inclined surface 87 with 52 inclined surfaces are engaged, the clutch operation is brought about because the lever 43 moves the coupling half '41 at the coupling half 37, when the spring can relax 53 ο It should be noted that the inclined surfaces 86, 87 fully rest on one another (Fig ₀ 7) or have a small distance, optionally can also be designed with a different slope. The extent of the incline in the circumferential direction, which leads to a coupling opening even after a time dependent on the height of the steps and their distance from the incline, is such that a copy sheet remains in a certain position after a stop pulse from the switch 8, "
