## Abstract

A method for automatically receiving image data in a facsimile system regardless whether such a facsimile system is operating in either a private line mode or a public line mode. The method includes the steps of: automatically receiving the image data in an automatic reception mode upon reception of a ring signal; forming a voice speech upon detection of a hook-off state of a telephone after the ring signal is received; and automatically receiving the image data when the ring signal is not received and a calling tone signal is detected.

## Claims

### Claim 1

A method for automatically receiving image data in a facsimile system including a telephone operable in one of a private line mode and a public line mode, said method comprising the steps of:
automatically receiving said image data from a telephone line regardless of whether said facsimile system is operating in one of said private line mode and said public line mode, upon reception of a ring signal responding to an incoming call when said facsimile system has been set in an automatic reception mode, said private line mode indicating that said facsimile system is directly connected to another data transmission system, and said public line mode indicating that said facsimile system is connected to another data transmission system through a public switch telephone network;
forming a voice speech upon detection of a hook-off state of said telephone after said ring signal is received from the telephone line, when said facsimile system has not been set in said automatic reception mode; and
automatically receiving said image data when said ring signal is not received but a calling tone signal is detected from the telephone line.

### Claim 2 (depends on 1)

The method of claim 1, further comprised of generating a standard ring tone in response to reception of said ring signal from the telephone line to inform of an incoming call.

### Claim 3 (depends on 2)

The method of claim 2, further comprised of determining whether a function key has been entered by an operator when the telephone remains on-hooked while the standard ring tone is generated in response to reception of the ring signal from the telephone line, and enabling the facsimile system to perform a function corresponding to said function key entered by the operator.

### Claim 4 (depends on 3)

The method of claim 3, further comprised of determining whether a function key has been entered by an operator when the telephone remains on-hooked and there is reception of said ring signal, and enabling the facsimile system to perform a function corresponding to said function key entered by the operator.

### Claim 5 (depends on 1)

The method of claim 1, further comprised of determining whether a function key has been entered by an operator when the telephone remains on-hooked and there is reception of said ring signal, and enabling the facsimile system to perform a function corresponding to said function key entered by the operator.

### Claim 6 (depends on 1)

The method of claim 1, further comprised of said data transmission device corresponding to one of a remote facsimile system and a remote telephone system.

### Claim 7

A method for automatically receiving image data in a facsimile system including a telephone operable in one of a private line mode and a public line mode, said method comprising the steps of:
generating a ring tone upon reception of a ring signal from a telephone line connected directly to one of a public switch telephone network and another data transmission device in response to an incoming call;
detecting whether said facsimile system has been set in an automatic reception mode regardless of whether said facsimile system is operating in one of said private line mode and said public line mode, upon generation of said ring tone;
forming a voice speech upon detection of a hook-off state of said telephone when said facsimile system has not been set in said automatic reception mode, and alternatively, when said ring signal has not been received from the telephone line;
determining whether a function key has been entered by an operator when the telephone remains on-hooked;
performing a function corresponding to said function key entered by the operator; and
automatically receiving said image data upon detection of a calling tone.

### Claim 8 (depends on 7)

The method of claim 7, further comprised of said function key being determined when the telephone remains on-hooked while the standard ring tone is generated in response to reception of the ring signal from the telephone line.

### Claim 9 (depends on 7)

The method of claim 7, further comprised of said function key being determined when the telephone remains on-hooked and there is reception of said ring signal.

### Claim 10 (depends on 7)

The method of claim 7, further comprised of said data transmission device corresponding to one of a remote facsimile system and a remote telephone system.

### Claim 11

A facsimile system operable in one of a private line mode and a public line mode, comprising:
means for automatically receiving image data from a telephone line regardless of whether said facsimile system is operating in one of said private line mode and said public line mode, upon reception of a ring signal responding to an incoming call when said facsimile system has been set in an automatic reception mode, said private line mode indicating that said facsimile system is directly connected to another data transmission system, and said public line mode indicating that said facsimile system is connected to another data transmission system through a public switch telephone network;
means for forming a voice speech upon detection of a hook-off state of said telephone after said ring signal is received from the telephone line, when said facsimile system has not been set in said automatic reception mode; and
means for enabling automatic reception of said image data when said ring signal is not received but a calling tone signal is detected from the telephone line.

### Claim 12 (depends on 11)

The facsimile system of claim 11, further comprised of a finger for generating a standard ring tone in response to reception of said ring signal from the telephone line to inform of an incoming call.

### Claim 13 (depends on 12)

The facsimile system of claim 12, further comprised of a sensor for determining whether a function key has been entered by an operator when the telephone remains on-hooked while the standard ring tone is generated in response to reception of the ring signal from the telephone line, and enabling the facsimile system to perform a function corresponding to said function key entered by the operator.

### Claim 14 (depends on 13)

The facsimile system of claim 13, further comprised of said sensor for determining whether a function key has been entered by an operator when the telephone remains on-hooked and there is reception of said ring signal, and enabling the facsimile system to perform a function corresponding to said function key entered by the operator.

### Claim 15 (depends on 11)

The facsimile system of claim 11, further comprised of a sensor for determining whether a function key has been entered by an operator when the telephone remains on-hooked and there is reception of said ring signal, and enabling the facsimile system to perform a function corresponding to said function key entered by the operator.

### Claim 16 (depends on 11)

The facsimile system of claim 11, further comprised of said data transmission device corresponding to one of a remote facsimile system and a remote telephone system.
