is gradually moved past the exposure lenses.

Patented in the German Empire on October 19, 1907.

With the previous series devices, this is endless, unwound from the middle of a roll and then rewound tape around the periphery of the roll, usually arranged so that it is perpendicular from the or horizontal position located roll past the exposure opening and the Exposure lenses. The movement of the picture book is done by

ίο a pulling effect exerted on it. These The arrangement and type of movement of the endless picture book can easily lead to damage

^ · The same, because the inner turns are the at

W long ribbons often have to carry several kilograms of outer coils of the ribbon, which easily damages the touching image ribbon surfaces. Furthermore, the pull exerted on the picture tape causes its surface to be slightly wrinkled and rendered unusable. The risk of such changes in shape of the illustrated book is increased by its weight.

The aim of the invention is to 'guide and move the illustrated book in such a way to ensure that such damage is prevented.

In the drawings, FIG. 1 shows an embodiment of the present picture tape guide and drive device in a side view, partially shown in section along the line AA in FIG. 2 , and FIG. 2 shows a top view of the device with the cover removed.

The device is carried by a frame, the upper part of which consists of a vertical Support arm 3 and an adjoining horizontal support arm 4, which is provided at one end with an upwardly directed fork piece 5. On the Support arm 4 is a cylindrical housing 6 attached, which on the circumference in a tangential Extension 7 expires and is provided with a removable cover 8. On the The bottom of the housing 6 is mounted in the middle of the photo book carrier 10, which can be rotated about the pin 9, \ velcher has the shape of a horizontally lying disc on its upper side carries a flat annular flange 11 between its outer circumference and the pin 9, which, like the grooved washer 12 attached to the underside of the carrier 10, is concentric to the pin 9 lies. The illustrated book 13 is not previously on one in the drawing The coil or drum shown is wound, the circumference of which corresponds to the outer circumference of the annular flange 11 corresponds, so that the tape roll can be placed around this flange. On one side of the housing 6, one end of an arm 14 is rotatably attached, which placed over the housing and with its other end at 15 (Fig. 2) releasable with the Housing wall can be connected. This arm 14 carries a on its underside conically tapered downwards, resting against the inner circumference of the picture tape roll Guide roller 16. Before loading the image

tape roll, the arm 14 is folded up, then the tape is inserted and then the arm 14 lowered again so that its guide roller 16 is rolled up against the inside of the Illustrated book. The photo tape 13 is moving upward through a transverse overlaid rod 17 prevents which 'in opposing openings der'Gehäusewandung. is stored and for the purpose of removing the picture tape roll from the housing 6 can be pulled out.

The free, outer end of the illustrated book is passed through the housing wall and placed around an inclined guide roller 18, which is provided with end flanges and in the extension 7 of the housing 6 is mounted. The belt 13 passes from the roll 18 a roller 19 mounted on the pin 20 and having a number of teeth on its circumference is provided, which is provided in the known manner on the edge of the illustrated book Engage holes. The inner end of the roll of picture tape goes over the roll 16 to an in the fork piece 5 mounted guide roller 21 and from this via a guide roller 22 in in a known manner to the image window 26. From there it is via rollers, namely last via the inclined roller 18, fed back to the roll of picture tape.

In order to drive the photo book carrier 10 and thereby at the same time the photo book without pulling action To wind up and unwind, an endless belt 32 is used in a known manner, which lies in the grooved pulley 12 and from this via the guide roller 33, 34 and 35 of the support arm 4 and via the one around the pin 37 rotatably mounted roller 36 of the support arm 3 is guided.

By turning the crank 42, the carrier 10 is rotated by means of the belt 32 offset, with the image book 13 stored thereon from the inner circumference the roll unwinds and after going through the path described on the outer periphery the roll winds up again.'Die roll 16 leads by virtue of its shape which is tapered downwards the picture book 13 gently over the flange 11, without subjecting it to any pulling action. The flange 11 or an equivalent supporting device for the tape roll is required to keep the tape on when rewinding Protect the outer circumference of the roll of picture tape against shifting and twisting.

The fact that the tape roll lies horizontally in the device described, that is is placed on edge, the individual turns of the roll are not affected by the weight the latter adversely affects, as is the case with the hanging arrangement of the roller.

In this way, damage to the surfaces of the illustrated book that touch one another is completely excluded, since the windings lie on top of one another concentrically without friction or with only very little friction. This effect is attributable to the difference between the inner and outer diameter of the roll of picture tape, since with each revolution of the carrier 10 the strip of tape unwound from the inside is rewound on the outer circumference of the roll and a slight pressure is exerted on the inner turns of the tape which is sufficient to hold the roll loosely on the flange 11 without causing strong friction between the individual turns of the picture book. Of course, the picture tape roll must slide while unwinding on their wing loose, however, the 8 <K ursacht here on the edge portion of the tape off a practiced friction no damage comparable by ■■■.

Characterized in that the carrier 10 of the shelves together will roll 32 g stored by the overall the face cam 12 * belt for particularly of the driving device for the image band rotated harmful Zugwirkungen be completely ruled out on the image band.

Of course, the carrier 10 of the illustrated book can be horizontal within certain limits also be arranged at an angle, because to achieve the desired effect of the described Device is only required that the'Bildbandrolle upright on a lying, by the drive device of the illustrated book particularly driven carrier rests.
