Abstract

For sending mail automatically, letters put in a sending station uncovered are scanned with a television camera tube, and the information is transmitted to storages in a telephone exchange. In the exchange, a numerical destination address written at a specified point is evaluated. With the aid of this destination address a path to the destination is set up automatically, preferably at night when there is little traffic, and the letter information is then transmitted. At the receiving station the information is reproduced and the letter is sealed before being delivered to the addressee.

Claims

1. Apparatus adapted to provide letter mail service through a multiple exchange telecommunications switching network, including a plurality of sending and receiving stations, each station being associated with a telecommunications exchange of said network and coupled thereto over telephone lines, each station including means for receiving a letter in the form of at least one sheet of paper containing information including a letter message and destination address, means at a station for validating input conditions for said letter for signalling the associated exchange accordingly, means at said exchange responsive to said signal at one station for seizing a path over one of said telephone lines to idle memory means in its associated exchange in response to a letter placed therein, means at said station for reading the message and for sending said message to said associated exchange over said path, a memory store in the memory means of said associated exchange for storing the address and message information read from said letter, means operative on a request and responsive to stored address information for completing respective telecommunications paths through the switching network to destination exchanges represented by a portion of the respective stored address information, means for transmitting said stored message and address information for all letters from said sending exchange to the respective destination exchanges, means at the respective destination exchanges for storing said received message and address information within a memory store, means for reading said received message and address information from said last-mentioned memory store, and means at a receiving station associated with said destination exchange for printing each message and address read from said store as letter information on a sheet of paper.

2. Apparatus as claimed in claim 1, wherein said means for reading the message at said one station comprises electro-optical scanning means activated to read the message from said letter sheet.

3. Apparatus as claimed in claim 2, wherein said one station includes check controlled means responsive to sensing of cash for activating said electro-optical scanning means.

4. Apparatus as claimed in claim 1 including means for sensing the presence of a letter at said station in position for reading by said electro-optical scanning means, said letter-sensing means operative on the sensing of a letter for causing the read-out of said message for transmission.

5. Apparatus as claimed in claim 4, wherein said one station further includes means responsive to storage of the message information for producing a receipt for said letter.

6. An electronic letter service system including letter sending devices each connected to a center via a line, each said device being equipped with an apparatus for receiving sheets of letter paper up to a predetermined size, means responsive to a signal from said apparatus for activating a path to said center, electrooptical scanning means in each device for reading information contained on a sheet of letter paper inserted in said device, switching means controlled responsive to information read from the letter for transmitting said information to the center, storage means at said center in which letter information including a destination address received from a letter sending device connected to the center is stored for subsequent transmission at a convenient time, and receiving devices at other centers in said network capable of being reached from said first-mentioned center via further lines and containing means for reproducing the letters directed to that other center in permanent visible form, the invention in which each center is incorporated in a telephone exchange of a telephone network and utilizes normal components of the exchange thereof, that the letter sending devices are connected to the first-mentioned center via telephone lines of the type used for telephone subscribers, control switching means of said network cooperative with the storage means to evaluate on an individual basis the respective destination addresses stored as part of the stored letter information for transmitting the respective control information necessary to set up a path in the telephone network to a telephone center corresponding to the evaluated destination address, and means for causing the associated stored information to be transmitted over the setup telephone path to receiving devices in a telephone center corresponding to the destination address for recording the received information thereat.
