Abstract

PURPOSE:To prevent disturbance to sleeping by setting the reception mode to be the non-ringing call reception mode in which no call tone rings automatically when a surrounding light goes off and to be restored to the automatic mode where a call tone rings automatically in the morning. CONSTITUTION:When the facsimile equipment receives a signal, an analog signal from a telephone line 7 is received by a telephone / NCU circuit 6, which gives the received signal to a MODEM LSI 5. It converts the signal into digital signal data, which are fed to a control block. When an optical sensor 8 receives a light, its resulting current goes to a high level signal through a resistor, 9 and the signal is fed to a control LSI 1. In this case, the control block 10 controls the telephone/NCU circuit 6 via the MODEM LSI 5 to be set to the automatic mode. When no light is received, a low level signal is fed to the control LSI 5, the control block 10 controls the telephone/NCU circuit 6 via the MODEM LSI 5 to be set to the non-ringing call reception mode. The reception mode is selected depending on the presence of the surrounding light in this way.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching of a reception mode of a facsimile machine which transmits information by connecting to a telephone line.

[0002]

2. Description of the Related Art When receiving a telephone call or receiving a facsimile with a single telephone line, a facsimile machine has a function of switching a receiving mode to manual, automatic, and absence, and further, a receiving mode by a timer setting. Has a function of setting the daytime and nighttime, and setting the ringtone to ring in the automatic mode during the daytime and not ringing in the silent ringing mode during the nighttime.

[0003]

However, when it is desired to switch the reception mode in accordance with the time when the user goes to bed, that is, the time when the light is turned off, the fixed time setting cannot be handled and each person operates to switch the reception mode before the light is turned off. However, when I got up, I had to bother with the settings of the reception mode.

It is an object of the present invention to provide a function of automatically switching to a non-ringing incoming call mode when turned off.

[0005]

In order to achieve the above object, an optical sensor capable of detecting light around a facsimile apparatus is provided so that the receiving mode can be automatically switched and restored depending on the intensity of light. Is.

Further, when the light becomes weak, the operation of the optical sensor is switched to the non-ringing incoming mode, and in the morning, the timer mode is set to return to the automatic mode.

[0007]

[Function] In the selection of the reception mode, the light sensor detects that the light is strong in the daytime, the automatic mode is selected, the ringing tone sounds, the telephone receiver can be picked up to talk, and at night, the room light is turned off to turn on The sensor detects that the light is weak and selects the silent ringing mode, so there is no need to make settings one by one.

Further, by selecting the non-ringing incoming call mode by detecting the light sensor when the light is turned off at night and returning by specifying the time by the timer setting in the morning, more stable and fine switching can be performed regardless of summer solstice or winter solstice. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows a facsimile system block. Control LSI 1, real-time clock IC 2, read-only memory 3, microprocessor 4, modem L
SI5 is connected to each other by a data bus and an address bus, and constitutes a control block 10 for the basic operation of the facsimile. When the facsimile receives, the telephone / NCU circuit 6 receives the analog signal from the telephone line 7 and the modem LS.
The data is sent to I5, and the modem LSI 5 converts it into a digital signal and sends the data to the control block. When the light sensor 8 receives light, it becomes a HI signal by the resistor 9 and is sent to the control LSI 1. At this time, the control block 10 controls the telephone / NCU circuit 6 via the modem LSI 5 to set the automatic mode. When light is not received, LOW signal is control LS
In I1, the control block 10 controls the telephone / NCU circuit 6 via the modem LSI 5 to set it to the non-ringing incoming mode. In this way, the reception mode can be switched according to the presence or absence of ambient light. Also, the real time clock IC2 can be set to the automatic mode at a certain time, and can be set to the silent ringing mode when no light is received.

[0010]

As described above, according to the present invention, the receiving mode becomes the ringing-free incoming call mode in which the ringing tone does not automatically sound when the light is turned off, and the automatic mode in which the ringing tone sounds automatically in the morning is restored. , It has the effect of not disturbing sleep. In addition, if the morning return time is designated by the timer setting, the mode can be switched when the light is turned off and when the user wakes up, and a more convenient reception mode can be realized.
