Dictating machine arranged like a telephone handset
This is a continuation of application Ser. No. 814,479, filed Dec. 30, 1985, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     The invention relates to a device for transducing speech signals, comprising a mouth piece and an ear piece provided remote from each other on either side of a handgrip, the handgrip, the ear piece and the mouth piece being part of a housing like a telephone hand set. 
     Such handsets are generally known, and some are intended for cordless operation. Telephone handsets of such a type are extended to a complete telephone set by incorporating the dialling mechanism in the handgrip. The dialling mechanism is constituted by a numerical keyboard whose circuit arrangement is included in the handgrip. 
     A car telephone is known, in which the handset can be accommodated on a cradle on the dashboard of a motorcar. The connecting cable of the car-telephone hand set is connected to a transmitter and receiver arrangement provided in an appropriate place in the motorcar. 
     In addition, pocket dictating machines are known, with which a message spoken into a microphone can be recorded on a magnetic tape. The message stored on the magnetic tape can then be reproduced again via a loudspeaker. Pocket dictating machines of such a type are generally of a compact, rectangular shape, so that they are light and easy to transport. 
     SUMMARY OF THE INVENTION 
     The invention has for its object to provide a device of the type defined in the opening paragraph, which is implemented as a dictating machine and can more specifically be used as if it were the handset of a car telephone in a motorcar. 
     According to the invention this object is accomplished in that the housing includes a recording device for magnetic tape cassettes. 
     By incorporating a recording device for magnetic tape cassettes, the device in the shape of a telephone hand set can be used as a dictating machine, the mouth piece including the recording microphone and the ear piece including the reproduction loudspeaker or the receiver. Such a device can be used in a motorcar as if it were a car-telephone; with this device it is also possible to pretend as if the motorcar were provided with a car-telephone connection. 
     Preferably, the recording device is incorporated in the handgrip of the housing. Cordless telephones have a housing that in the region of the handgrip already has such a width that a tape transport mechanism of a magnetic tape cassette device can be accommodated therein without any further measures. 
     In accordance with a further embodiment of the invention, the control keys of the recording device are provided in a generally flat face in the transition area between the handgrip and the ear piece or the mouth piece, respectively, and a start/stop key is arranged on the side of the handgrip. In such a configuration, the operating keys can be appropriately operated without visual control of the fingers of the relevant hand. 
     In a further embodiment of the invention, a coiled power cable has a plug for insertion in a socket in a motorcar. When this socket is, for example, the jack of a cigarette lighter, then no special provisions need to be built into the car for operating the device. Only a hook or carrier must be provided somewhere in the dashboard of the motorcar to enable locating of the dictating machine as if it were a car telephone. 
     The invention will now be described in greater detail by means of example with reference to the embodiments shown in the drawing. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     FIG. 1 is a side elevational view of a dictating machine in the form of a telephone handset, 
     FIG. 2 shows the dictating machine of FIG. 1 in a plan view from the operating side and 
     FIG. 3 is an elevational side view of a dictating machine as shown in FIGS. 1 and 2, provided in a motorcar dashboard. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The dictating machine 1 shown in FIG. 1 comprises an elongated housing 5, having a mouth piece 3 and an ear piece 4 arranged, remote from each other, at opposite ends, and facing in the same general direction so that the mouth piece 3 may be adjacent a user&#39;s mouth when the ear piece 4 is held against the user&#39;s ear. Between the mouth piece and ear piece the housing 5 is shaped as a handgrip 2. The housing 5 of the dictating machine 1 has consequently the shape of a telephone handset. 
     FIG. 2 shows in a plan view the modified structure of the dictating machine 1 as compared with a customary dictating machine and as compared with a customary telephone handset. A tape cassette deck 6 of a dictating machine is arranged between the mouth piece 3, which includes a microphone, not shown, and the ear piece 4, which includes a loudspeaker capsule not shown, in the handgrip 2. The dictating machine is, for example, suitable for using so-called mini or micro cassettes. Such a magnetic tape cassette 7 is accommodated behind a cover 8 for access through the cover. 
     For operating the recording device 6 control keys 9, 10, 11, 12, 13 are provided, distributed over the transition area 14 between the handgrip 2 and the ear piece 4 and also over the transition area 15 between the handgrip 2 and the mouth piece 3. In this embodiment the keys 9 and 11 for fast forward and rewind and also the recording keys 10 are arranged in the transition area 14. The on-off key 12 is located in the transition area 15. Preferably a large key 13 at the side of the handgrip 2 is used for starting and stopping the tape transport in the play/record mode. 
     As shown in FIG. 3, the dictating machine 1 can be placed by means of its housing 5 on a carrier 16 in the dashboard 17 of a motorcar. The connecting cable 18 for the dictating machine 1 is coiled and has at its free end 19 a plug 20 for insertion in a socket. When the machine is used in a motorcar, the plug 20 may, for example, be of such a structure that it fits in the socket of a cigarette lighter. 
     With such a structure and such an arrangement of a dictating machine it can not be distinguished from a motorcar telephone. Consequently, such a dictating machine can be provided, ready to hand, in the customary location of a car telephone in a motorcar.
