“The microphone fork usually has a built-in switch on, which cooperates with the power supply circuit in such a way that it is interrupted when the microphone is on the fork hung up. The electrical and mechanical connection between the microphone fork and the dictation device is designed in such a way that after removing the microphone fork, the device can be operated by means of the main switch is controllable, which forms part of the dictation machine itself. Without the fflikrophongabsl the device has a compact shape; unwanted projections are avoided, so that the device is ideal for use as a portable device Device is suitable. If, on the other hand, the microphone fork is attached to the dictation machine, the microphone switch takes over The microphone fork automatically controls the control, so that any further manipulation of the main switch of the dictation machine is avoided You will then begin or end dictation target. The device is switched on by simply lifting the microphone from the fork; Placing the microphone on the fork switches the device off. The time that elapses before the microphone is removed and put into the normal dictation position is generally sufficient to adjust the mechanical components of the dictation machine to the required level Speed up, as modern electronic solid-state drive units do not require a heating-up tent.

Basic features, advantages and possible uses of the invention emerge from the subclaims and from the following description of an exemplary embodiment in conjunction

continuous collecting line 17 and a current-carrying line 18 connected. The line 18 is connected to a main switch 19, by means of which the power supply is switched on and off u »ird and the sinen are part of a volume control can. The main switch 19 is connected to a metallic sleeve 21 of a first socket 20 which is accessible from the outside and is formed on the bottom of the dictation machine 10, this can be seen from FIG. A second socket 22 is located is also on the underside of the device. From the socket 22 leads the line 18 to the elements 16 »

The circuit components between points X and X ¹ in FIG. 1 are illustrated in more detail in FIG that it closes the inner end of the socket 22 and at the same time makes contact with a terminal 24 which is connected to the sleeve 21. In the normal case, a closed circuit is therefore established, which leads via the line 18, the main switch 19, the terminal 24 and the spring 23.

As can best be seen from FIG. 3, the microphone fork has a foot 30 from which two fork arms 31, 32 extend, on which the normally supplied together with the dictation machine lYlikrophone (which also serve as a display element can) can be placed on the foot 30 of the liqueur fork

Pins 34,35 are provided which fit into sockets 20,22. These pins are also indicated schematically in FIG. One of the pins, in the illustrated embodiment the pin 35 which fits into the socket 22, has a length such that when the foot 30 of the microphone fork is pressed against the bottom of the dictation machine 10 it deflects the spring 23 against the biasing force upwards, whereby the connection interrupted with terminal 24. The socket 20 made of conductive material comes into contact with the pin 34. As a result, a circuit is established which leads from point X (line 18) via the pin 34 in the base 30 of the microphone fork via a normally closed switch 36 to the pin 35, which is in contact with the leaf spring 23, which in turn is connected to the Point X ^{1 is} connected "

The normally closed one associated with pin 34 Switch 36 is mounted in fork arm 31. The switch 36 has a switch pin 38 which protrudes over the fork arm and comes into engagement with the microphone, man the microphone is placed on the fork in its rest position. The switch can be a microswitch, for its opening only a very small switching range and a very low gauiicht required If the switch pin 38 is pressed down by the weight of the microphone, it is pushed over the pins 34, 35 leading circuit open. The power supply to the elements 16 is consequently interrupted when the microphone placed on the fork and "After lifting the microphone
