a scanner unit configured to scan a script of a transmission target so as to generate image data of the script; and

a processor configured to execute a process including:

generating a command for transmitting the image data to the transmission destination by using the obtained transmission destination information;

converting each character constituting the command into a binary number;

embedding, in an area of a portion of the image data, dot data of the command, the dot data being represented by a dot that corresponds to the binary number; and

transmitting the image data in which the dot data has been embedded, to the relay device via fax communication.

2. The transmission device according to claim 1 , wherein the embedding embeds the dot data in a top of the image data.

3. A relay device comprising:

a memory; and

a processor configured to execute a process including:

obtaining image data in which dot data of a command has been embedded, the dot data being represented by a dot that corresponds to the binary number;

obtaining the dot data of the command from the image data;

converting the dot data that is the dot data of the command and is represented by the binary number into a character corresponding to the binary number;

analyzing the command represented by a character string formed by the characters; and

transmitting the image data to a transmission destination specified by the command by using a transmission method represented by the command as a result of the analysis of the command.

4. The relay device according to claim 3 , wherein

the transmitting transmits the image data to a transmission destination specified by the command via the fax transmission when a result of the analysis of the command indicates that the command is a request for transmission via fax communication, or transmits the image data to a transmission destination specified by the command via the electronic mail when a result of the analysis of the command indicates that the command is a request for transmission via an electronic mail.

5. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process for transmitting data, the process comprising:

obtaining a fax number of a relay device and transmission destination information that determines a transmission destination;

scanning a script of a transmission target so as to generate image data of the script;

generating a command for transmitting the image data to the transmission destination by using the obtained transmission destination information;

converting each character constituting the command into a binary number;

embedding, in an area of a portion of the image data, dot data of the command, the dot data being represented by a dot that corresponds to the binary number; and

transmitting the image data in which the dot data has been embedded, to the relay device via fax communication.

6. The non-transitory computer-readable recording medium according to claim 5 , wherein the embedding embeds the dot data in a top of the image data.

7. A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process for relaying data, the process comprising:

obtaining image data in which dot data of a command has been embedded, the dot data being represented by a dot that corresponds to the binary number;

obtaining the dot data of the command from the image data;

converting the dot data that is the dot data of the command and is represented by the binary number into a character corresponding to the binary number;

analyzing the command represented by a character string formed by the characters; and

transmitting the image data to a transmission destination specified by the command by using a transmission method represented by the command as a result of the analysis of the command.

8. The non-transitory computer-readable recording medium according to claim 7 , wherein

the transmitting transmits the image data to a transmission destination specified by the command via the fax transmission when a result of the analysis of the command indicates that the command is a request for transmission via fax communication, or transmits the image data to a transmission destination specified by the command via the electronic mail when a result of the analysis of the command indicates that the command is a request for transmission via an electronic mail.

9. A control method of a transmission system that transmits information from a transmission device to a transmission destination via a relay device, the control method comprising:

obtaining, by using the transmission device, a fax number of the relay device and transmission destination information that determines a transmission destination;

scanning, by using the transmission device, a script of a transmission target by using a manipulation unit so as to generate image data of the script;

generating a command for transmitting the image data to the transmission destination by using the obtained transmission destination information;

converting, by using the transmission device, each character constituting the command into a binary number;

embedding, in an area of a portion of the image data, dot data of the command, the dot data being represented by a dot that corresponds to the binary number, by using the transmission device;

transmitting, by using the transmission device, the image data in which the dot data has been embedded, to the relay device via fax communication;

obtaining, by using the relay device, image data in which the dot data of a command has been embedded, the dot data being represented by a dot that corresponds to the binary number;

obtaining, by using the relay device, the dot data of the command from the image data;

converting, by using the relay device, the dot data that is the dot data of the command and is represented by the binary number into a character corresponding to the binary number;

analyzing, by using the relay device, the command represented by a character string formed by the characters; and

transmitting, by using the relay device, the image data to a transmission destination specified by the command by using a transmission method represented by the command as a result of the analysis of the command.
