Facsimile system having a proximity sensor for automatically switching reception mode based upon presence or absence of an operator within a predetermined proximity zone and method for controlling the same
First Claim
1. A facsimile system operable in one of a telephone mode and a facsimile mode, comprising:
- an operational panel for permitting setting of said facsimile system at an installation maintained by a user, in an automatic switch mode;
a proximity sensor for sensing whether said user is within a proximity zone of said installation; and
a controller for automatically switching an operation mode of said facsimile system from said telephone mode to said facsimile mode, when said facsimile system is set in said automatic switch mode and when the user is not within said proximity zone of said installation;
wherein said proximity sensor is selected from a group consisting of an infrared sensor for sensing whether body heat is present within said proximity zone of said installation and a motion sensor for sensing whether motion is present within said proximity zone of said installation.

Abstract
A facsimile system having a proximity sensor for automatically converting an operating mode such as a telephone mode, a facsimile mode, a telephone/facsimile mode, and a telephone answer mode of a facsimile system. The facsimile system includes an key input unit for allowing a user to set the facsimile system in an AUTO mode; a proximity sensor for sensing whether the user is within a proximity zone of the facsimile system; and a controller for automatically changing an operation mode of the facsimile system from the telephone mode to the facsimile mode, when the facsimile system is set in the AUTO mode and when the user is not within the proximity zone of the facsimile system.

2. A facsimile system operable in one of a telephone mode and a facsimile mode, comprising:
-
an operational panel for permitting setting of said facsimile system at an installation maintained by a user, in an automatic switch mode; a proximity sensor for sensing whether said user is within a proximity zone of said installation; and a controller for automatically switching an operation mode of said facsimile system from said telephone mode to said facsimile mode, when said facsimile system is set in said automatic switch mode and when the user is not within said proximity zone of said installation; said proximity sensor further comprising; a microphone for detecting a level of ambient sound external to said facsimile system to produce an electric signal; a band-pass filter for filtering the electric signal from said microphone to produce a filtered signal; an amplifier for amplifying the filtered signal to produce an amplified signal; and an audio signal detector for determining whether said user is within said proximity zone of said installation based upon reception of said amplified signal. - View Dependent Claims (3, 4, 5, 6, 7, 8)

9. A facsimile system having a telephone handset and operable in one of a telephone mode, a facsimile mode, a telephone/facsimile mode, and a telephone answer mode, said facsimile system comprising:
-
input means having at least an automatic mode key for enabling setting of said facsimile system at an installation maintained by a user, in an automatic switch mode; a proximity sensor for sensing whether said user is within a proximity zone of said installation; and controller means for automatically changing an operation mode of said facsimile system from any one of said telephone mode, said facsimile mode, and said telephone/facsimile mode into said telephone answer mode, when said facsimile system has been set in said automatic switch mode and when the user is not within said proximity zone of said installation; wherein said proximity sensor is selected from a group consisting of an infrared sensor for sensing whether body heat is present within said proximity zone of said installation and a motion sensor for sensing whether motion is present within said proximity zone of said installation.

10. A facsimile system having a telephone handset and operable in one of a telephone mode, a facsimile mode, a telephone/facsimile mode, and a telephone answer mode, said facsimile system comprising:
-
input means having at least an automatic mode key for enabling setting of said facsimile system at an installation maintained by a user, in an automatic switch mode; a proximity sensor for sensing whether said user is within a proximity zone of said installation; and controller means for automatically changing an operation mode of said facsimile system from any one of said telephone mode, said facsimile mode, and said telephone/facsimile mode into said telephone answer mode, when said facsimile system has been set in said automatic switch mode and when the user is not within said proximity zone of said installation; said proximity sensor further comprising; a microphone for detecting a level of ambient sound external to the facsimile system to produce an electric signal; a band-pass filter for filtering the electric signal from said microphone to produce a filtered signal; an amplifier for amplifying the filtered signal to produce an amplified signal; and an audio signal detector for determining whether said user is within said proximity zone of said installation based upon reception of said amplified signal. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for automatically converting an operation mode of a facsimile system having a key input unit with an automatic mode key, said method comprising the steps of:
-
checking whether said automatic mode key has been input for setting said facsimile system operable in one of a telephone mode, a facsimile mode, a telephone/facsimile mode, and a telephone answer mode, at an installation maintained by a user, in an automatic switch mode; after said automatic mode key has been input for a predetermined duration, determining whether said user is within a proximity zone of said installation; when said user is within said proximity zone of said installation, maintaining the operation mode of said facsimile system in any one of said telephone mode, said facsimile mode, said telephone/facsimile mode, and said telephone answer mode previously set by said user; and alternatively, when said user is not within said proximity zone of said installation, automatically changing the operation mode of said facsimile system from any one of said telephone mode, said facsimile mode, and said telephone/facsimile mode into said telephone answer mode; said user being determined within said proximity zone of said installation by a proximity sensor including; a microphone for detecting a level of ambient sound external to said installation to produce an electric signal; a band-pass filter for filtering the electric signal from said microphone to produce a filtered signal; an amplifier for amplifying the filtered signal to produce an amplified signal; and an audio signal detector for determining whether said user is within said proximity zone of said installation based upon reception of said amplified signal. - View Dependent Claims (18, 19, 20)
