[0009]

However, the multi-function peripheral cannot grasp the state of the personal computer and cannot change the response time to the calling signal.

By the way, recent notebook computers are often driven by batteries and often have a resume function for reducing power consumption. In such a personal computer, it takes time to return from the resume state to the normal state. Also, the time depends on the personal computer. In the case of the configuration shown in FIG. 6, since it is not known what kind of personal computer is connected, how to absorb the above time becomes a problem.

That is, the conventional systems have the following problems.

Since the line of the telephone line was opened after the ringing tone of the telephone line sounded a certain number of times, depending on the state of the personal computer (when the personal computer is in the resume state or the hard disk is in the sleep mode), the programs and the hard disk may not start up in time. Instead, important received data may be missed.

Even when the facsimile cannot be received due to the cause of the apparatus or the personal computer, the telephone call is received, and thus unnecessary telephone charges are incurred.

When a facsimile cannot be received due to the cause of the apparatus or the personal computer side, the other party who made the call does not know what the cause is that the facsimile cannot be received.

[0015]

FIG. 3 shows a call signal from the telephone line (upper waveform), where a signal of 75 V, 16 Hz is 1
Comes for 2 seconds, no signal for 2 seconds, 75V, 1 second again for 1 second
I understand because 6Hz is coming.

The output signal from the call signal detection circuit for detecting the call signal from the telephone line (lower waveform) is high for 1 second and low for 2 seconds. The CPU 1 judges this signal, and when it becomes high for the number of times corresponding to the number of CI signal responses, the telephone line is closed.

7 and 8 are flow charts showing the operation of the multi-function printer of the embodiment.

This flowchart shows a call signal from the telephone line (hereinafter referred to as CI) depending on the state of the personal computer.
By changing the response time to (the number of times the CI of the telephone line closes the DC circuit), the personal computer waits until it is ready to receive a facsimile disk.

The state between the personal computer and this apparatus at this time may be as follows.

This device is not connected to a personal computer (CI signal response count: n = 2) When this device is connected to a personal computer and the personal computer is on (CI signal response count: n = 2) When the personal computer is connected to the personal computer and is in the resume state (temporary stop state) (CI signal response count: n = 10) When the device is connected to the personal computer and the personal computer is powered off (CI signal response) Number of times: n = 2) When this device is connected to a personal computer and the hard disk device of the personal computer is in a sleep state (number of CI signal responses: n = 6). It is determined in advance whether the DC circuit is closed (CI signal response count = n).

In the example of this flow chart, and are set to n = 2, = 10, and = 6. The reason for this is that the time it takes for the computer to be ready in the
It was 28 seconds in the actually confirmed environment, and C
Since the period of the I signal is 3 seconds from FIG. 3, 3 seconds × 10 times = 3
It will be 0 seconds and will be ready in 10 times, which is greater than 28 seconds. It should be noted that this time, of course, varies depending on the environment (the state of the personal computer of each company), and is not fixed. This also applies to the following.

The reason is that the time required for preparing the personal computer confirmed in the embodiment was 16 seconds. In other words, 3 seconds × 6 times = 18 seconds, which is longer than 16 seconds, and the preparation is completed.

Since the personal computer cannot be used in the states of and, the multifunction printer apparatus itself receives data by setting n = 2 (memory reception or printing at a certain time in the printer).

In the state of (2), since the personal computer is already prepared, the facsimile is received by the hard disk of the personal computer with n = 2.

In practice, the method for determining the numerical value of n is C
If the time N between the time when the I signal comes first and the telephone line goes off-hook to start sending the facsimile image data to the personal computer and the time P until the personal computer is ready to receive the image data are the same or P Since the faster the speed, the better. Therefore, N ≧ P, and an appropriate value of n is obtained from this value.

The determination as to whether or not the apparatus in the embodiment is connected to the personal computer is realized as follows.

That is, the personal computer side writes the state (status) of the personal computer into the I / F with the multifunction printer device every time the state of the m personal computer changes. When the present apparatus, that is, the multifunction printer apparatus wants to know the state of the personal computer, it grasps the state of the personal computer by reading the data.

Next, the contents of the receiving process of the apparatus of the embodiment will be described with reference to the flowcharts of FIGS.

First, in step S101, it is determined whether or not a CI signal (first CI signal) has arrived, that is, whether or not there is an incoming call.

When the CI signal is received (step S10)
1) Read the state of the personal computer and activate the personal computer (step S102). Next, in order to determine the value of the variable n (which is secured in a predetermined area of the RAM 4) that determines the standby time depending on the state of the personal computer, step S1
It branches to any of 04-S106.

The determination of this branch is as described above. In the case of the state and, the process branches to step S104, in the case of the state to step S105, and in the case of the state to step S106. . Then, in each step, the value of the variable n is set to either 2, 6, or 10.

Now, when the value of the variable n is set in this way, the process proceeds to step S107 and waits until the number of times of receiving the CI signal becomes the same as the variable n.

In this way, when the number of times the CI signal is received becomes equal to the variable n, the process proceeds to step S108 to perform the process of closing the DC circuit. That is, the telephone line is taken off-hook and the facsimile reception is started. When facsimile reception is started, the process proceeds to step S109,
Depending on the state of this device and the personal computer, step S110,
It branches to any of S111. Here, the state,
In case of, that is, the PC is not connected, or
If the personal computer is connected but its power is off, the process proceeds to step S110. If the state is either or, step S1
Proceed to 11.

In step S110, the received facsimile image (encoded image data) is stored in the RAM 4 or the facsimile image is decoded and printed by the printer 8 in real time.

In the case of the mode for storing in the RAM 4, for example, it is judged in step S112 whether or not the contents of the memory have overflowed, and if it occurs, a paper end error is sent to the sender facsimile machine. Is returned (step S113). In addition, step S113 is executed even when the paper end is reached during execution of printing in real time.

On the other hand, if the process branches to step S111, it means that the personal computer is in a state at this point, so that the received facsimile image is transferred to the printer I / F 11 (the bidirectional is It is sent to the personal computer side by using the above-mentioned) and stored in the storage device (memory, floppy disk, hard disk, etc.) built in the personal computer.

In this way, when one facsimile reception process is completed, the DC circuit is opened and the line is cut off.

As described above, since the facsimile image data is sent from the multifunction printer device after the personal computer side is ready, there is no need to worry about the data being dropped.

Further, even a person who tries to send a facsimile image does not have a communication error, so that unnecessary telephone charges are not incurred.

[Explanation of the Second Embodiment] Next, the second embodiment will be explained. However, the device configuration is the same as that of the first embodiment, and the description thereof is omitted.

9 and 10 are flow charts showing the operation of the second embodiment.

(A) When the device 22 is in the paper end state (no recording paper) and the personal computer is not connected, (B) When the device is in the paper end state and the personal computer is connected, When the power is off
(C) When the apparatus is in the paper end state, the personal computer is connected, and the hard disk (facsimile storage destination) has no free space, except for the CI signal, as in the first embodiment. Set the number of responses.

Next, the actual operation will be described with reference to the flow charts (FIGS. 9 and 10).

First, in step S201, it is determined whether or not a CI signal (first CI signal) has arrived, that is, whether or not there is an incoming call.

When there is an incoming call, the process proceeds to step S202 to check the state of the personal computer. Then, step S20
At 3, the state of the device 22 is also checked.

In step S204, step S20
2. From the determination result of S203, it is determined whether the facsimile reception is possible or not.

If the reception is impossible, the process returns to step S201 and no response is made to the reception of the CI signal. The unreceivable status is any of the above judgments (A), (B), and (C).

If the reception is possible (at least when the apparatus is not in the paper end state), the process proceeds to step S205. Since step S205 and subsequent steps are exactly the same as step S103 and subsequent steps in the first embodiment, description thereof will be omitted.

As described above, if both the multifunction printers cannot receive the facsimile after the preparation of the personal computer side, no response is made even if the call signal comes, resulting in unnecessary telephone charges. It becomes possible to lose it.

[Explanation of Third Embodiment] Next, a third embodiment will be explained.

FIG. 11 shows a block diagram of the apparatus in the third embodiment. In the figure, the first and second
What is different from the embodiment is that a function (voice synthesis circuit 26) for transmitting a voice is added. This voice synthesis circuit 2
The output of 6 is sent to the telephone line. The other configurations are the same as those of the first and second embodiments, and the description thereof will be omitted.

12 and 13 are flow charts showing the operation of the third embodiment.

This flowchart is for the reason that the personal computer is in the following states (A) to (C) and the reason why the facsimile cannot be received by the voice synthesizing circuit 26 of the telephone line even when the call signal comes from the telephone line. It is meant to inform.

The state of a personal computer that cannot receive a facsimile is the following case.

Next, the flowchart (FIGS. 12 and 13)
The actual operation will be described using.

First, in step S301, it is determined whether or not a CI signal (first CI signal) has arrived, that is, whether or not there is an incoming call.

When there is an incoming call, the process proceeds to step S302 to check the state of the personal computer. Then, step S30
At 3, the state of the device 22 is also checked.

In step S304, step S30
2. From the determination result of S303, it is determined whether the facsimile reception is possible or not.

If it is determined that the facsimile can be received, that is, none of the above conditions (A) to (C), the process proceeds to step S308. Since the processing after step S308 is the same as that of the first embodiment, the description thereof is omitted here.

If it is determined that reception is not possible, the process proceeds to step S305.

In step S305, the DC circuit of the telephone line is closed and the off-hook is performed. Then, step S306
Then, the reason why the facsimile cannot be received on the telephone line is sent by the voice synthesizing circuit 26.

Then, the process proceeds to step S307, the DC circuit is opened, that is, on-hook, and then step S30.
Return to 1.

As described above, when neither the personal computer side nor the multifunction printer device can receive the facsimile, the reason why the facsimile cannot be received can be notified to the other party of the facsimile via the telephone line. Since it is not necessary to send a facsimile many times, it is possible not only to avoid unnecessary telephone charges, but also to instruct the apparatus to receive a facsimile.

[Description of Fourth Embodiment] A fourth embodiment will be described. The device configuration in the fourth embodiment is the same as that of the third embodiment.
The description will be made assuming that it is similar to the embodiment of

In the present embodiment, when the apparatus side cannot receive a facsimile, the voice synthesizing circuit 26 switches between transmitting a voice message to a telephone line and a non-voice error signal.

More specifically, when a calling signal is received from the telephone line, the state of the personal computer is as follows (A).
In the case of (C), CN when the DC circuit of the telephone line is closed.
When the G signal is received, it can be determined that the partner device is not a human but a facsimile device. Therefore, the facsimile is once received and an error suitable for the state of the device is returned. When the CNG signal does not come, the reason why the facsimile cannot be received is notified to the other party by the voice synthesizing circuit 26 via the telephone line.

The states of the personal computer that cannot receive the facsimile are as follows.

(A) When the multifunction printer device is in the paper end state and the personal computer is not connected, (B)
When the multifunction printer is in the paper end state and the personal computer is connected but the power is not turned on, (C)

If the person is a person, a message is sent out over the telephone line to inform the person of the reason why the person cannot communicate. As a result, the content of the error can be notified in a language suitable for each partner (facsimile device or person).

The CNG signal is transmitted at the time of automatic facsimile transmission, and is not transmitted at the time of manual transmission (when a person dials from the telephone to transmit a facsimile). Also, the CNG signal does not come during a normal telephone call, so when a person is listening to the sound of the telephone line,
It is designed to send a message.

Further, in the above embodiment, when the device 22 is in the paper end error state and the personal computer is not connected, or even if it is connected, the personal computer is turned off or the personal computer is turned on. However, when the hard disk has a small capacity, facsimile reception (reception of image data) was not performed, but the free space of the RAM 4 of the device 22 (the free space when the hard disk device is installed in the device) If it is sufficient, you may make it receive on behalf. In this case, a predetermined LED or the like is turned on in order to inform the operator that the substitute reception has been performed.

Further, the device 22 determines whether the hard disk in the personal computer has sufficient free space by sending a predetermined command requesting the personal computer to transfer the information, and obtaining the information from the personal computer. is there. Therefore, on the PC side, when an application that supports facsimile reception receives the command,
The free space of its own hard disk is transmitted to the device 22.

However, when the power supply of the personal computer is off, no response is returned even if such a command is generated. In this case, the operator looks at the display section of the device 22 and confirms that the proxy reception has been performed, turns on the power of the personal computer, issues a transfer request command for the received image to the device 22, and receives the received image.
