 The device according to the invention makes it possible to avoid any connection to the telephone line, the various automation functions are provided very simply by means of servo-mechanisms ensuring the opening and closing of electrical contacts.

 This patent relates to an automatic telephone recording and answering machine which can operate without being connected to the telephone line.

- FR-A-2.555.384
Device allowing a selective and automatic connection between a telephone answering machine recorder remotely searchable and an automatic call device.

 Place between the answering machine and the automatic call system, it allows, thanks to a counting logic and an storage system, to validate the command of a transistor driving an output relay. A reset system allows the device to be restarted with each A call.

 This patent is particularly intended for radio and telephone telecommunications.

- FR-A-2.447.653
The invention relates to a computerized communication device using intercoms and telephones which allows messages to be stored for potential callers.

 In this device, a speech synthesizer is provided in connection with the computer, a selector placed on the subscriber's instrument and two additional push-buttons which control the speech synthesizer, in order to make it possible to compose and modify messages to potential applicants.

 This patent is the one that best defines the state of the art. It is complex since it requires a computer that manages messages and a voice synthesizer.

 It allows a precise and fast dialogue with the caller. Additional push buttons allow this dialog by answering questions with yes or no and allowing a rapid sequence of questions. All messages can be modified or canceled depending on the time. The caller cannot leave a message for the occupant.

Said device comprising a button which connects or disconnects the recording answering machine. The two positions of the button correspond to the "absent" or "present" situation of the occupant.

 Outside, the device comprises an intercom plate with its loudspeaker, its microphone and the different call button (s) which correspond to the different dwellings of the occupants. Finally, an electric strike allows the entry door to be opened remotely.

 Inside, the device includes the intercom part, with in particular its speaker-microphone handset, a call chime, a door opening button, a second button with two positions "present" or "absent". This button activates, in standby position, the recording answering machine itself.

 The attached drawings are given by way of non-limiting example. They represent a preferred embodiment according to the invention. They will allow the invention to be easily understood.

 Figure 1 is a schematic view, highlighting the relationships between the different organs, such as intercom plate, electric door strike, inner box.

 Figure Z is a more detailed view, according to Figure 1.

 The device according to the invention comprises outside, an intercom plate 1, with a loudspeaker 2, a microphone 3 and one or more call buttons 4 which correspond to the dwelling or to the various dwellings in the case of collective housing or co-ownership.

 An electric strike 5 enables the door opening to be operated remotely. Each of these elements 1, 2, 3, 4 and 5 are connected by electric cable 17, 1S, 19, 20, to an interior box 6 arranged in each apartment.

 Inside the room or the house, the box 6 includes the intercom part 7 and the answering and recording part 8.

 The intercom part includes a button 9 for opening the door by the electric strike 5. Another button 10 makes it possible to connect the device with or without answering machine 8. Said button 10 has two positions, an "absent" position, a "present" position. Finally, a handset 21 includes a speaker and a microphone.

 The answering and recording part 8 is represented in the diagram of FIG. 1 by two cassettes 11, 12. A cassette 11 for reading, a cassette 12 for recording.

 In Figure 2, the various electrical connections are shown. In the intercom part 7, the chime 13 is shown.

In part B of the answering machine-recorder are shown in addition, in Figure 2 with respect to Figure 1, the amplifier 14 and the speaker 15, as well as the micro-recorder 16 for messages.
