DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine, and more particularly to a facsimile machine equipped with a line monitor function that allows the user to listen to the contents of a line in an on-hook state.

(Prior Art) In a facsimile machine for manual transmission and reception, a telephone is usually connected to a line, and before sending or receiving a document, the operator takes the telephone off-hook to check that the other party's facsimile machine is connected to the line. , it was transitioning to send/receive mode. By the way, in recent years, in order to omit such telephone operations, in which the operator has to check the line status through the handset each time there is a transmission/reception, so-called voice output devices have been introduced that allow the operator to check the line status while on-hook. A facsimile machine equipped with

However, even with facsimile machines designed to omit such operations, for example, if the line status is checked and it is determined that it is possible to switch to send/receive mode, the receiver must be taken off-hook to switch to send/receive mode. However, it was insufficient in terms of effective use of the on-hook function, and there was room for improvement.

(Object of the Invention) Therefore, an object of the present invention is to provide a facsimile device that effectively utilizes the on-hook function by performing the series of steps from checking the line status to transitioning to the sending/receiving mode while remaining on-hook. The purpose is

(Structure of the Invention) In order to achieve the above object, the present invention provides an on-hook connection function that uses a line alternatively with a telephone, connects to the line in an on-hook state, and a monitor function that monitors the signal status of the line. A facsimile device comprising:
When a call is made or answered using the on-hook connection function and the monitor function confirms that the signal status of the line is a predetermined signal status, the system shifts to facsimile communication mode while remaining on-hook by pressing a certain key. It is something to do.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 3 are diagrams showing an embodiment of the present invention, which is applied to a facsimile machine equipped with a telephone function.

In FIG. 1, 1 is a facsimile machine.

The facsimile machine 1 includes a key power detector 2, an on-hook detector 3, an automatic receiving and transmitting device 4, a document detector 5, an audio output device 6, an off-footer detector 7, a display 8, a communication control section 9,
Line connection section 10, modem 11, CPU 12, ROM 13
and RAM14.

The key force detector 2 detects when a numeric keypad, one-touch key, or start key provided on an operation panel (not shown) is pressed by an operator, and generates a key operation signal SK indicating the operation content of the numeric keypad or one-touch key. Start signal SSt indicating that the start key has been pressed
output on the data bus. The on-hook detector 3 detects that the on-hook mode switch also provided on the operation panel has been pressed by the operator, and generates an on-hook signal S indicating that the switch has been pressed. 8 on the data bus. When the key operation signal SK is numeric keypad information, the automatic receiving and transmitting device 4 automatically calls the destination terminal (facsimile machine or telephone) according to the telephone number indicated in the information, and also when the key operation signal SK is one-touch information. In the case of key information, the corresponding telephone number is read out by referring to a destination dial table registered in the RAM 14, which will be described later, and the destination terminal is automatically called. Alternatively, when a calling signal CNd is input from the other party's terminal, the call is automatically answered and a line is established. Note that this automatic receiving and transmitting device 4 is equipped with an AA type network control device (so-called AA type network control device).
-NCU: Network Control
IJnit) is used. The document detector 5 detects that a document is set in the reading section (not shown) of the facsimile device 1, and outputs a document cent signal I)si7 onto the data bus.

The audio output device 6 is connected to the line based on a predetermined control signal Sc from the CPU 12, which will be described later, and amplifies and amplifies electrical signals such as voices and tone signals on the line. therefore,
The audio output device W6 has a monitor function □ for monitoring the state of line i8. Incidentally, at the same time as the voice output device N6 is connected to the line, the line is switched from the telephone to the facsimile machine 1. The off-hook detector 7 detects off-hook of the built-in telephone PINT of the facsimile machine 1, which will be described later, and generates an off-footer signal S. The FF is output onto the data bus and the line is switched to the facsimile machine 1. The display 8 is disposed on or near an operation panel (not shown) and displays various information output from the CPU 12 (to be described later) that prompts operator operations and input data such as telephone numbers as characters and graphics. The communication control unit 9 transmits and receives image information via the line connection unit 10 in accordance with a predetermined transmission control order when a transition to the communication mode is determined by the CPU 12 (described later). The line connection unit 10 includes a modem 11, which modulates the image information at the time of transmission into a signal format suitable for high-speed transmission and sends it out to the line, or demodulates the image information at the time of reception.

The audio output device 6, the line connection section 10, the modem 11, the built-in telephone PINT, and the external telephone P. The XT and the line have a connection relationship as shown in FIG. In FIG. 2, the line is connected to CM L (CurrentMo
The contact of the CML relay Kl is switched in accordance with a control signal Sc from the CPU 12, which will be described later, to connect the line from the external telephone PtXa to the isolation transformers T1 and T2. The isolation transformer T1 transmits the signal component in the line to the audio output device 6 through two contacts to the CML relay connected to the secondary side. Also, 2 is an off-hook signal S to the CML relay. The connection relationship is switched by the FF, and the signal component in the line is output to the built-in telephone aP+Nr, or the voice signal from the built-in telephone PINT is output to the line via the isolation transformer T1. The isolation transformer T2 transmits signal components (picture information data) on the line to the modem 11, or transmits picture information data from the modem 11 to the line.

Again, in FIG. 1, the CPU 12 executes the sequence as the facsimile machine W1 according to the program stored in the ROM 13. For example, various information output from each component above, key operation signal SX, start signal S
sT, on-hook signal S. N, original cent signal I)sE
The processing value necessary for transitioning to the communication mode in the on-hook state is calculated by reading data such as A, etc., and exchanging data with the RAM 14. That is, the control signal S, obtained as a result of the calculation, is output to the CML relay Kl of the line connection unit 10 to switch the contact, and the voice output device 6 is made to monitor the line status, and the line is connected from the telephone to the facsimile device 1. Switch to Further, a key operation signal SK is outputted to the automatic receiving/transmitting device 4 to prompt a calling operation. Therefore, the CPU 12 has an on-hook connection function together with the on-hook detector 3 that detects when the above-mentioned on-hook key is pressed and the automatic receiving and transmitting device 4 that automatically makes and answers calls. The RAM 14 temporarily stores various data used in calculations, and a portion of the RAM 14 is reserved as a reception area, in which a destination dial table is constructed.

Note that a built-in telephone PIN is connected to the facsimile device 1, and a regular subscriber telephone or a commercially available telephone is also connected as an external telephone PEXT. The off-hook of the built-in telephone PIN is detected by the aforementioned off-footer detector 7.
As a result, the line is switched to the facsimile machine 1, and facsimile communication in an off-hook state or a telephone conversation using the built-in telephone PINT is possible.

Also, the on-hook signal S from the on-hook detector 3 described above
. Even if there is an on-hook state where M is output, that is, a state where the facsimile machine and the voice output device 6 are already connected to the line, the built-in telephone PI is used instead of the voice output device 6 by outputting the off-hook signal S OFF.
NT is connected to the line, and it is possible to monitor the line status and talk to the other party using the built-in telephone PINT.

However, connection of the built-in telephone PIN 7 to the line is not allowed after transitioning to communication mode.

The operation will be described below with reference to the flowchart of the communication mode transition program in the on-hook state shown in FIG.

The communication modes described above are classified into a transmission mode for transmitting a document and a reception mode for receiving a document, so the operation of each mode will be described.

When the operator intends to send a document in the off-hook state, the operator first presses the on-hook switch on the operation section (not shown) of the main body of the facsimile machine 1.

As a result, the on-hook signal S from the on-hook detector 3
. N is output, and the step number of the program flowchart shown in Figure 3 (hereinafter abbreviated as P) 1
(PI), this on-hook signal S. Detect the output of N. That is, transition of the facsimile device 1 to the on-hook state is detected.

At P2, a control signal SC is output to the line connection section 10,
Switch 1 to CML relay, connect line and audio output device 6
connect with. Thereby, the audio output device 6 amplifies the line status. At this time, isolation transformer T
2 via modem 11, i.e., facsimile machine 1
are also connected to the line at the same time. The operator identifies the line closure when the amplified tone is a continuous dial tone, and inputs the telephone number of the other party using the numeric keys (or presses a registered one-touch key). Next, when a key operation signal SK is detected in P3, in P4, if this key operation signal SK is a telephone number, it is left as is, or if the key operation signal SK is a number for a one-touch key, it is retrieved from the telephone number table on the RAM 14. The registered telephone number corresponding to the number is read out and outputted to the automatic receiving/transmitting device 4 as a key operation signal SK. The automatic receiving/transmitting device 4 generates a selection signal based on the key operation signal SK, and sends the selection signal to the station via the communication control section 9 and modem 11. The station sends a paging signal CNG to the destination terminal indicated in the selection signal. That is, through these series of operations, a call is made to the destination terminal indicated by the key operation signal SK. The destination terminal makes 6 calls as a result of this call, and if it is a telephone, it will respond with a real voice, and if it is a facsimile machine, it will send a called station recognition signal CE D (2100Hz, 3 seconds). ) are sent back to the calling party. These real voices or called station recognition signals CED are amplified by the audio output device 6,
The operator listens to this amplified sound and executes a predetermined operation. That is, in the case of the called station recognition signal CED, the other party's terminal is a facsimile machine and is ready for reception, so the operator presses the start key. When the start key is pressed, a start signal SSt from the key force detector 2 is detected at P, and then an original set signal D SET is detected at P7 to identify whether or not an original is set. . That is, when a document is set, it is clearly intended to transmit the document, and in this case, the process advances to Pa and a transition to the transmission mode is determined. Therefore, the image information of the document is read and transmitted according to a predetermined sequence. On the other hand, if no original is set, this corresponds to, for example, a case of so-called polling reception in which the calling side receives image information from the called side, and in this case, P.

Proceed to and decide to switch to receive mode.

When the other party's terminal makes a call intending to enter the communication mode, the bell of the external telephone PEXT rings, and the operator presses the on-hook switch after hearing the bell.

This causes an on-hook signal S at the PI. detect N,
A control signal SC is output to the line connection section 10 at P2.

That is, the line is switched from the external telephone PEXT to the facsimile machine 1 and the voice output device 6, and is connected to the other party's terminal. The operator identifies that the other party's terminal is a facsimile machine by the amplified sound from the audio output device 6. Further, in this case, since the facsimile machine 1 on this side is the called side, it is not necessary to input a telephone number using a numeric keypad or the like. Therefore, the key operation signal s8 is not generated, and the process proceeds to P6 according to the NO command at P3.

At P6, the operation of the start key by the operator is detected, and at P, the document set signals D, , T are detected to identify the presence or absence of a document. In this case, since no original is set in the facsimile machine 1 on this side, the process proceeds to step P and shifts to the reception mode.

Note that in both the transmission mode and the reception mode described above, the off-footer signal S is transmitted before the mode is determined. F
When F is detected, 2 is switched to the CML relay of the line connection section 10, so that the built-in telephone PINT can be used to interrupt the line. That is, in the transmission mode, the user can prompt the other party to switch terminals (from a telephone to a facsimile machine), or in the reception mode, it is possible to respond to the other party's communication in real voice.

As described above, in this embodiment, the on-hook state is entered by pressing the on-hook key, and the line status is notified to the operator using an amplified sound. Furthermore, in the case of transmission, a telephone number is input using a numeric keypad or the like, a call is made to the destination terminal, and the destination terminal is identified as a facsimile machine by the response sound from the loudspeaker. When the terminal model is identified as a facsimile machine, the operator presses the start key.
As a result, the facsimile machine 1 detects that the document has been sent and automatically shifts to the transmission mode. That is, the operator can continuously carry out the process from placing the document to sending the document while remaining on-hook, and there is no need to go off-hook -H in the middle as in the conventional case. Therefore, you can make full use of the off-hook function,
The convenience of facsimile devices is improved.

(Effects) According to the present invention, the series of steps from checking the line status to transitioning to the transmission/reception mode can be performed while on-hook, and the on-hook function can be utilized as effectively as possible, and the convenience of the facsimile machine can be improved. can be improved.
