The normal movement of the belt 2 in these figures of the movement direction of the motor is indicated by the arrow 108 shown in FIG. 4 and 7 a to 7 c is shown. 107 drives a larger gear wheel 109 which, according to FIG. 5 and 11 in the arrow 40 lever 10 and the gripping device 50 the outermost direction 107 is rotated. When a band is deployed it will have reached the setting. At the end of the is, the gear wheels 107 and 109 are continuously driven by the sequence of movements reached by the gripper 53 an anMotor 105.

the actuation of the clutch 93. This drives the shaft 83 on which the drive screw spindle 100 is also arranged as shown in FIG. A rotary cam 94, which controls the actuating member 78 shown in FIGS. 5 and 19, is connected to the coupling 93. When the drive screw spindle 100 rotates, the cam 94 arranged on the shaft 83 rotates by a predetermined amount in order to indicate an initial position of the drive screw spindle 100 . As soon as this position is reached, the cam 94 actuates the actuating member 78, which in turn actuates the contacts 75 c. The device is designed in such a way that the pin 92 reaches the projection 84 a of the connecting member 84 shown in FIGS. 10 and 19 at this point in time. When the pin 92 strikes the shoulder 84a , the coupling 93 is released so that the rotation of the drive screw spindle 100 is interrupted. As already mentioned, during this process the contacts 75c are closed to indicate this condition.

After the drive screw spindle 100 has reached its initial position, the belt 2 is driven by the connection of the gear wheel 107 with the transport roller 64. The belt 2 was already driven before the drive screw spindle 100 had reached its starting position. The dictation device 1 includes the Abfühlkontakte shown in Fig. 19 97, which are intended, the opening la of the belt 2 sense. The sensing contacts 97 consist of an upper contact element 98, which extends through the opening Za , and a lower contact element 99, which is fastened to the magnetic head carrier 103.

The falling of the rotary lever 86 causes the connection 79 and the carrier 81 to put on the Magnetic head 82 on tape 2, and at the same time, through the movement of the pawl-P return arm87, which is also shown in Fig. 17a, the Re-engagement of the pawls on the drive screw spindle.

As a result of the processes mentioned, the tape 2 was brought into the operating position on the transport rollers 63 and 64, the drive screw spindle 100 reached its starting position, and the magnetic head 82 on the tape 2 was set to the beginning of the track. These processes occur in the dictation device 1 or in the listening device 5 every time the tape 2 is inserted into one of these devices. This automatically results in an exact track setting for these devices when the tape is put down. The other parts of the devices are designed in such a way that the exact tracking of the magnetic head is maintained during the other operating processes of a dictation or a wiretapping process.

Hinetyen of a tape that does not have standardized perforations

If the operator of the dictation machine 1 has the desire to use an endless belt on which the standardized opening 2 a is not provided when the dog ζ. B. the in F i g. .1 should weep openings 2b that deviate from the norm, then such a tape is first entered into the dictation device by the operator in the same way as was done for the standardized tape hanger . Because in this case I> Ιι · ι.ι ι; _{: i} v. i / en ύ '· \ Dog's arc in Fi μ. I ¹ ) d!

th contacts 97 cannot sense opening 2 «, there is no actuation of the switching magnet 89. In this case, however, the setting conditions for starting dictation in

S can be achieved in a simple manner that the dictation person in F i g. 1 actuated element 34 for the track advance of the magnetic head. This operation makes the switching magnet 89, and first causes the lifting of the locking element shown in Fig. 10 is 91, caused thereby, the rotary lever 86 to the actuator 74 and the carrier 81 to move. The dictation operation can then be started in the manner already described.

By moving the lever 10 shown in FIG. 1 to the right, the removal of the tape 2 from the dictation machine I is initiated. The actuation of the lever 10 causes the shortening of the length between the transport rollers 63 and 64

ao distance. It also controls the cam 73, causes the magnetic head 82 to lift off the tape, and causes the pawls 101 to release.

_{Correction a5 of} the track position carried out by manual operation

To correct the track position, the slide 23 shown in FIG. 1 is provided in the dictation machine. This causes a directed against a spring force adjustment of the drive screw 100. The slider 23 shown in Fig. 5 moves in a block 28 on the slide rails 42 and 43. The block 28 carries a pin 44 to which the actuator 47 with the Cam 41 is performed. The cam 41 controls a lever 76 which is rotatably mounted on the bracket 71 . The end of the lever 76 is supported against a spring force, not shown, against the end of the shaft 83. The spring, not shown, pushes the shaft 83 and the drive screw spindle 100 connected to it to the left. By manipulating the slide 23, the cam 41 controls the lever 76, as a result of which the shaft 83 and drive screw spindle 100 can be adjusted from left to right and from right to left. Since the pawls 101 shown in FIGS. 17a and 17b engage in the drive screw spindle 100 , the movement of the slide 23 results in an adjustment of the magnetic head 82, the tracks of which on the tape 2 can thus be corrected.

Preparing the dictation machine for dictation

Let it be assumed that the dictation machine has been set by setting the mode shown in FIG. 1 rotary knob shown! 20 has been set to "Dictation". The volume control 18 is set to a medium volume. This is followed by the onset of the band, as has already been explained. The operator then causes the introduction of a number of marking strips 12 into the frame 13. The magnetic head 82 is now on the tape 2 in its output

βο position, and the lag results accordingly of the scanning slide 16 with respect to the marker line fensIS. As can be seen from Fig. 1, the discharge is Slide 16 moved slightly from its starting position to the right. The magnetic head 82 can durc
