Abstract

An electronic control unit (6), powered from the mains, responds to the ringing of the telephone bell through a connected microphone (1). This signal energises a solenoid coil (2) which, through a system of cranks and levers and springs (3,4,5), simulates lifting of the hand set. This action completes the control unit and initiates the replay unit (7) to transmit a message through a loudspeaker (3) to the microphone in the hand set. After a set time, the replay unit is switched off and a recorder (9) switched on. An incoming message can be recorded. If there has been no speech for a period, for example 8 seconds, the recorder is switched off and the coil (2) de-energised. The instrument is then ready to accept a further call.

Kreillerstrasse 68 8000 Munich 80 Rudolf Frank Brandenburgerstrasse 47 8500 Nuremberg Jürgen Schraut Karolinenstr. 30 8510 Fürth Description of title: mechanical answering machine for TeleConapparete Field of application: The invention relates to a mechanical answering machine for given telephone desk sets the post.

Purpose: A "substitute function" is created from such additional devices for the telephone required in the absence of the telephone owner, whereby the answering machine automatically records a message from the other party.

State of the Techp: ik: It is common knowledge to meet this Requirements to operate answering machine devices with the help of a postal socket.

Criticism of the state of the art: This creates an application processing time, Connection and monthly fees, as well as an inpatient dependency on the post office.

Continuation of the description of "Mechanical answering machine" Task: The invention is based on the object of attracting new customers by saving costs to offer a postal network-independent answering machine that without interfering with of the postal network and its systems is operated.

Solution: According to the invention, this object is achieved in that the Answering machine telephone desk phones operated mechanically and via a @ acoustic Operation, messages transmitted and recorded. Despite this mechanical The way the answering machine works is security even in the event of a power failure of the telephone set.

Obtainable advantages: The advantages achieved with the invention exist in particular in offering XX an answering machine device that is independent of the postal network, that is only connected to the lighting network. Included. becomes an application processing time as well as connection and monthly fees saved.

Description of the embodiment: The embodiment of the invention is shown in the drawing and is described in more detail below. continuation the description "Mechanical answering machine" Description of the execution: Figure 1: The microphone (1) reacts acoustically to the ringing of the telephone set and gives an electrical impulse to the electronic part (6) of the answering machine, wherein the electromagnet (2) overcomes the compression spring force (4) via the linkage (3) and the button (5) is moved to the position shown in FIG. This is the telephone set released for a conversation.

Figure 2: The electronics (6) first control the speech set (7), which forwards a text to the conversation partner via the loudspeaker (8). To a time of max. 50 sec.

(according to FTZ 18 R 2, Referat A 52-6, April 74) the message is at ended the call partner. The electronics (6) switch off the speech unit (7) and the recorder (9) stores a message sent through the microphone (1) is recorded.

If a speech pause of 8 seconds is exceeded, the Electronics (6) the recording device (9) and the electromagnet (2). The compression spring (4) hringt dj. Button (5) back in the position of Figure 1 continuation the description "Mechanical answering machine" Description of the execution: Thus the answering machine is ready for a subsequent long-distance call (Figure 1). These control solutions with the aid of the compression spring (4) and the electromagnet (2) show that the security of the telephone set is guaranteed even in the event of a power failure is.
