Abstract

PURPOSE:To eliminate a wasteful power consumption by executing the calling to the telephone number of a telephone registration when a main power source is turned off and to the telephone number of a facsimile registration when the main power source is turned on, at the time of operating one touch dial key. CONSTITUTION:When a main power source is turned on, a changing-over circuit 57 is connected to a make contact M, and when for example, a dial key A to constitute an one-touch dial key 58 is pushed, the dial information selected by the inverting signal of C1 and the inverting signal of R6 is generated by a dial IC 56. The said dial information is a telephone number registered as a facsimile device. When the main power source is turned off, the changing-over circuit 57 is connected to a break contact B, and in the same way, when the dial key A is pushed, the dial information, which is a telephone number registered by the purpose of a conversation selected by the inverting signal of the C1 and the inverting signal of R4, is generated by the dial IC 56.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine having a one-touch dial calling function.

[Prior Art] Conventional facsimile machines have a function that allows one-touch dialing only when the 100V power supply is on, and when the same one-touch dial is operated, the facsimile machine The destination of the call is different from the other party's address.

Therefore, in the conventional device, when making a call, always t
Since the oov power supply must be turned on, power may be wasted. Even if a standby power supply is provided, there is a problem in that about 10 to 5 W of power is wasted.

[Object of the Invention] The present invention has been made by paying attention to the problems of the above-mentioned conventional devices, and it is an object of the present invention to provide a facsimile device that does not consume power unnecessarily.

[Embodiments of the invention] FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, a crystal oscillator 1 generates a reference clock for the entire device, and this clock is given as a reference clock to a CPU (central processing unit) 2 comprised of a desired microprocessor or the like. CpU2t*, ROM3. RAM4, timer 5, PPI (propramable parallel l10)
6.7.10. UPI (Peripheral CPU) 9.11.12
is connected to. The CPU 2 controls the entire facsimile machine and also encodes and decodes image data.

Roughly, the CPU 2 controls calling to the telephone number of the other party registered as a telephone by operating the 1-touch dial key when the main power supplied to the dialer 16 is turned off, and when the main power is turned on, the CPU 2 This is an example of means for controlling a call to a telephone number of the other party registered as a facsimile machine by operating a touch dial key.

The DMA controller 3 controls memories such as the ROM 3 and RAM 4, and the UPI 9 controls the drive of originals and recording paper. Also, UPI 11
is for controlling the parallel-to-serial converter 25 and the recording system of the thermal radar, and the UPI 12 is for controlling the key λ.
The switch 31 performs display on the liquid crystal display LCD 32.

The modem 14 modulates and demodulates one image data and transmits and receives procedure signals for facsimile communication procedures.
The control unit (NCU) 15 switches the line to the telephone 34 side or the modem 14 side.

The dialer 16 sends a dial signal to the line in response to telephone number data of the communication device output from the CPU 2 via the PP17.

In addition, a relay 8, a speaker drive circuit 18, a speaker 19, an analog-to-digital converter 21, a telephone circuit 29, and a switch 35 are provided.

FIG. 2 is a circuit diagram showing details of the telephone circuit 29 shown in FIG.

The telephone circuit 29 includes a detection circuit 50.51 and a ring IC 5.
2, piezoelectric buzzer 53, and speech network IC5
4, pulse dial drive circuit 55, and dial IC5
6, a switching circuit 57, and a one-touch dial key 58.

The switching circuit 57 switches the connection state between the one-touch dial key 58 and the dial IC 56 according to whether the main FL source is turned on or off.

FIG. 3 is a circuit diagram showing the one-touch dial key 58 and the switching circuit 57 in more detail.

The switching circuit 57 has two relays, and is connected to the make contact M when the main power is on, and connected to the break contact B when the main power is off.

Next, the operation of the above embodiment will be explained.

dial key A that constitutes the one-touch dial key 58;
B, C1, I, J are each one key, and even if they are the same l touch dial key (for example, key A), the main power When the machine is on, the telephone number of the other party to be used as a facsimile machine is registered, and when the main power is off, the telephone number of the other party to be used as a telephone is registered.

That is, in FIG. 3, when the main power is on, the switching circuit 57 is connected to the make contact M, and when the 1-touch dial key A is pressed, for example, the switching circuit 57 is selected by the inverted signal of CI and the inverted signal of R6. Dial information, Dial I
C56 occurs.

In this case, since the main power is on, the dial information is a telephone number registered as a facsimile machine.

On the other hand, when the main power is off, the switching circuit 57 is connected to the break contact B, and when the 1-touch dial key A is pressed at this time, the dial information selected by the inverted signal of CI and the inverted signal of R4 The dial IC 56 generates. In this case, since the main power is off, the dial information is a telephone number registered for the purpose of conversation.

In this way, even if you press the same 1-touch key A, the dialed phone number changes depending on whether the main power is turned on or off, so you can register more phone numbers than before with fewer 1-touch dials. Can be done.

In addition, in the above embodiment, since it is possible to dial the other party's telephone when the power is off, the main power must be turned off at all times to make a call, and the main power must be turned on only when the user wants to use it as a facsimile machine. For example, the overall power consumption is lower than before.

In FIG. 2, the ring IC 52, the speech network IC 54, and the pulse dial drive circuit 55 operate by receiving power from the telephone line, so even if the main power is turned off, the above circuits operate, and therefore, the above circuits can make calls. Calling, receiving a call, sending a call, and receiving a call operate without any problems even in the event of a power outage or when the main power switch of the facsimile machine is turned off.

On the other hand, the parts shown in FIG. 1 are all driven by a +5V, ±12V DC power source generated from a 100V main power source. Therefore, transmission or reception as a facsimile device operates only when the main power of the facsimile device is on.

By the way, when using a small, personal, integrated facsimile/telephone facsimile machine on a desk, most of the space is used as a telephone, and the facsimile machine can only communicate less than five times a day. is common. In this case, when the user has a facsimile/telephone with a standby machine, even if its standby power is only a few watts, it is necessary to turn off the main power and use the telephone a.
By using only the residue, the overall power consumption can be further reduced.

In the embodiment shown in FIG. 3, the one-touch dial keys are A, B, C1..., I, J, and in this case, the other party's facsimile machine 10 telephone numbers can be registered, and 10 telephone numbers of the other party with whom one wants to have a conversation can be registered, for a total of 20 telephone numbers.

On the other hand, in the conventional device shown in FIG. Although the number of keys is twice that of the embodiment, the number of telephone numbers that can be registered is the same as 20.

[Effects of the Invention] According to the present invention, the present invention has been made by focusing on the above-mentioned dark problems of the conventional device, and has the effect that unnecessary power consumption can be greatly reduced.
