Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus of the present invention.

The facsimile apparatus according to the present embodiment shown in FIG. 1 selectively operates in the presence mode, which is the operation mode when a person is in the room, and in the absence mode, which is the operation mode when the person is not in the room. An operation key input unit 1 for switching setting, an optical sensor 2 for detecting whether or not indoor brightness, that is, indoor illuminance is equal to or more than a predetermined detection reference value, and outputting an illuminance detection signal 12, The presence / absence mode setting signal for receiving the illuminance detection signal 12 from the optical sensor 2 and setting the presence mode by determining that a person is present when the illuminance in the room is greater than or equal to a predetermined detection reference value 13 is output to a control unit (not shown), and when the illuminance in the room does not reach a predetermined detection reference value, it is determined that no person is present in the room and the presence / absence mode is set to set the absence mode. Mode setting The signal 13 is output, and the presence / absence mode setting signal 13 for setting the presence mode is output when the presence mode setting input is performed from the operation key input unit 1 even when the absence mode is set. The presence / absence operation mode setting unit 3 that outputs the presence / absence mode setting signal 13 for setting the absence mode when the absence mode setting is input from the operation key input unit 1 even during the setting, and the operation key. The optical sensor 2 receives the sensitivity instruction input signal 14 from the input unit 1.
And a photodetection sensitivity adjustment section 4 for outputting a photodetection sensitivity adjustment control signal 15 for adjusting the photodetection sensitivity.

Next, the operation will be described.

In FIG. 1, the optical sensor 2 detects whether the illuminance in the room is greater than or equal to a predetermined detection reference value and outputs an illuminance detection signal 12. The presence / absence operation mode setting unit 3 receives the illuminance detection signal 12 from the optical sensor 2,
When the illuminance in the room is equal to or higher than a predetermined detection reference value, it is determined that a person is in the room and the presence / absence mode setting signal 13 for setting the presence mode is output to the control unit.
When the illuminance in the room does not reach the predetermined detection reference value, it is determined that no person is present in the room and the presence / absence mode setting signal 13 for setting the absence mode is output to the control unit. Even when the absence mode is set by the output from the optical sensor 2, when the absence mode setting input is performed from the operation key input unit 1, the presence of the presence mode for prioritizing the manual control and setting the absence mode is performed. The absence mode setting signal 13 is output to the control unit. Further, even when the presence mode is set, when the absence key setting is input from the operation key input unit 1, the presence mode setting signal 13 for setting the absence mode is output to the control unit. That is, normally, the presence / absence operation mode setting unit 3 automatically sets the presence / absence operation mode to either the presence mode or the absence mode according to the brightness of the room based on the output from the optical sensor 2. It is like this. Also, for example, if you want to keep the presence mode when an important incoming call is expected even when the room is dark after going to bed at night, or if the room is bright and the fax machine is in the absence mode. When it is desired to place it in, the mode that has been set can be changed by the mode setting instruction input signal 11 from the operation key input unit 1. When it becomes unnecessary for a person to change the setting by the mode setting instruction input signal 11, the mode setting instruction input signal 11 for canceling the mode setting instruction input by manually controlling the operation key input unit 1 to release the mode setting instruction input is provided. By outputting to the presence / absence operation mode setting unit 3, the presence / absence operation mode setting unit 3 returns to a normal state in which the presence / absence operation mode is automatically set by the output of the optical sensor 2. When going to bed or leaving the office, turn off the lighting in the room where the fax machine is installed, or pull the curtain of the window to block the light entering the room to darken the room, or lock the shutters to lock the door. Even if the room is darkened by doing so, it does not become sufficiently dark depending on the condition of the equipment in the room. Therefore, when it is necessary to change the reference value of the brightness that distinguishes the presence mode from the absence mode, the operation key input unit 1 is used. When an instruction input for adjusting the light detection sensitivity of the optical sensor 2 is performed, a sensitivity instruction input signal 14 is output from the operation key input unit 1 to the optical sensor 2. Light detection sensitivity adjustment unit 4
Outputs a light detection sensitivity adjustment control signal 15 for adjusting the light detection sensitivity of the optical sensor 2 to the optical sensor 2 by the sensitivity instruction input signal 14 from the operation key input unit 1, and the optical sensor 2 detects a predetermined detection. The reference value is changed to the instructed value, and thereafter, the illuminance detection signal 12 based on the changed detection reference value is output to the presence / absence operation mode setting unit 3. After that, the presence / absence operation mode of the facsimile apparatus is set as the absence mode even if the room is not sufficiently dark.

In this way, when going to bed or leaving the office, the illumination lamp in the room in which the facsimile device is installed is turned off,
Or, by pulling out the curtain of the window to block the light entering the room to darken the room, or by closing the shutters and closing the door to darken the room, there is no human presence in the darkened state. It automatically changes from the presence mode to the absence mode, and when you wake up or come to work, it changes from the absence mode to the presence mode. There is no need to change to the absence mode, or to change from the absence mode to the presence mode when getting up or coming to work. For example, if the room where the fax machine is installed is bright during the day and always dark after going to bed at night,
Since the absent mode is automatically changed to the absent mode after going to bed at night, even if a facsimile call arrives after going to bed, it can be dealt with in the absent mode without human trouble. Only when necessary, the operation key may be used to change from the presence mode to the absence mode, or from the absence mode to the presence mode. Further, since the optical sensor detects this when the room is darkened, it is immediately set to the absence mode of the person.
