Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of receiving a telephone number of a calling side sent from an exchange side before a line is closed and transmitting called image to send image information to the calling side. It is about.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus is known which can perform called transmission (for example, polling transmission, retrieval transmission, remote control transmission, etc.) for transmitting image information to a calling side. For example, the polled transmission as the called transmission will be outlined below. First, a transmission document is set on the document table of the called facsimile machine, and polling transmission is designated by the function key of the called facsimile machine. As a result, the called facsimile machine is on standby for polling transmission. When a call signal is received from the calling facsimile machine while waiting for polling transmission, the line is closed and signals are exchanged according to a predetermined communication control procedure. At this time, when the called facsimile receives a DTC signal, which is a polling transmission command, from the calling facsimile, the called facsimile reads the transmission document on the platen with a scanner and the calling facsimile The image information is transmitted to the facsimile machine. The above is the polling transmission.

On the other hand, such a facsimile machine is also capable of ordinary call reception for receiving image information transmitted from the calling facsimile machine. At this time, the called facsimile machine can perform not only recording paper reception for printing the received image information on recording paper but also memory reception for recording the received image information as image data in an image memory.

In such a conventional facsimile apparatus, when the call reception is impossible, such as when the recording paper is not set or when the image memory capacity is insufficient, even if the call transmission is performed. Even if I was waiting, I tried not to close the line.

This is for the following reason. In other words, if the line is closed even if the called facsimile machine is in a state where it cannot receive, the calling facsimile machine is called during the signal exchange performed according to the normal communication control procedure. When the facsimile machine on the calling side requests to receive the transmission image information, the facsimile machine on the called side cannot open the line because it will open the line, but during this period, from line closing to line opening. This is because the telephone charge is charged to the caller during the period, which causes a disadvantage to the caller.

That is, it is unreasonable for the calling facsimile to pay only the telephone charge even though the image information could not be transmitted to the called facsimile. Therefore, in the past, the line was not closed at all when the called facsimile machine was incapable of receiving.

[0007]

However, when the called facsimile machine is in the unreceivable state but waiting for polling transmission, it is assumed that the calling facsimile machine intends to perform polling reception. However, since the called facsimile machine does not close the line at all, as a result, the calling facsimile machine cannot perform polling reception.

For example, since the above-mentioned conventional facsimile apparatus can generally receive a called call while waiting for polling transmission, the called facsimile is received during polling transmission waiting and the recording paper is used up. In some cases (if there is no free memory in the model that can receive the memory), the line will not be closed because no reception is possible in such a case. In this case, if the called operator does not notice the fact, the calling facsimile cannot continue polling reception.

The present invention has been made in view of the above problems, and when the called party is on standby, the calling party can respect the intention of the called party when the called party may perform the called transmission. The purpose is to provide a facsimile machine. Well
In addition, the present invention prevents a caller from being charged a telephone charge unnecessarily when the called party is waiting to receive a call and cannot receive the call, when the caller is a party who is unlikely to perform the call transmission. It is an object of the present invention to provide a facsimile device that can respect the will of the other party when there is a possibility of transmitting a call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a facsimile apparatus of this embodiment, FIG. 2 is an explanatory diagram of blocks in FIG. 1, FIG. 2A is an explanatory diagram of an image memory, and FIG.
FIG. 2C is an explanatory diagram of the AM, and FIG. 2C is an explanatory diagram of the operation unit.

In FIG. 1, a facsimile machine 1 (herein called "callee" for convenience) is connected to a telephone line 16a via a network control unit (NCU) 2 for controlling the line. The telephone line 16a is connected to a called side exchange 17, the exchange 17 is connected to a calling side exchange 18 via a telephone line 16b, and the exchange 18 is connected to a facsimile machine 19 (here Is called for convenience sake).

A call signal enters the called facsimile machine 1 through the exchanges 18 and 17 in response to the dialing operation of the caller. At this time, if the called party has registered in the called exchange 17 as a subscriber of the telephone number receiving service on the calling side, there is no sound between the first calling signal and the next calling signal. In the section, it is a switching system in which the telephone number on the calling side is sent to the facsimile machine 1 on the called side via the switching system 18 and the switching system 17, and has already been put to practical use in an analog switching system in the United States. The present invention relates to a terminal device for such a switching system.

The CPU 3 which is the core of the facsimile apparatus 1
Is connected via a signal bus line 4 to the following various parts of the device and controls each part of the device in accordance with a predetermined communication control procedure (see FIG. 3) to execute a facsimile operation, that is, data communication. The modem 5 transmits and receives various procedure signals for transmission control while modulating and demodulating and transmitting image information, and the buffer 6 is encoded to be transmitted and received to and from the facsimile device 19 on the calling side. The data including the image information is temporarily stored.

The ROM 7 is a memory that stores a control program, and the EEPROM 8 is a memory that stores various setting information and the like. Further, the RAM 9 is a memory for temporarily storing various data at the time of execution of the operation, and as shown in FIG. 2A, a calling side telephone number memory 9a for storing the sent calling side telephone number, A mode memory 9b for storing the transmission / reception mode set in the facsimile apparatus 1 is provided. The image memory 10 is a dynamic RAM
An image data storage area 10a configured by a (DRAM) or the like and storing image data as shown in FIG.
(Memory receiving area 101, transmitting area 102, called transmission area 103), and a bit image storage area 10b for storing a bit image for recording.

The operation unit 11 is, as shown in FIG.
The operation state of the facsimile device 1 is displayed on the display 11d.
Are displayed by the operator and are used by the operator to perform various operations.
1b, speed dial registration key 11c and the like. The function key 11b includes a transmission / reception mode setting menu, and a polling transmission mode for transmitting an original to the facsimile device 19 on the calling side can be selectively set. The polling transmission mode selected and set is R
It is stored in the mode memory 9b of AM9.

The encoder 12 encodes image information to be transmitted, and the scanner 13 reads an image of a transmission original. The decoding unit 14 reads the received image data stored / written in the buffer 6 or the image memory 10 for recording and performs decoding. The printer 15 records the received image data on the recording paper 15b. For example, the printer 15 forms a latent image on a photoconductor by laser light,
An electrostatic electrophotographic recording method is used in which it is developed with toner and transferred to the recording paper 15b. The image data is compressed and encoded by the run length method, for example, and is transmitted and received.

The printer 15 is provided with a recording paper sensor 20 which outputs a predetermined signal when the recording paper 15b is not attached to the printer 15 or is attached but used up. Normal reception operation of the facsimile machine 1 (records in real time when received)
The facsimile apparatus 1 includes a calling side facsimile apparatus 19 and telephone lines 16a, 16b, 16
After being connected to the NCU 2 via the CPU c and the exchanges 17 and 18, both facsimile machines 1 and 1 are controlled by the CPU 3.
After transmitting and receiving a signal according to a predetermined communication control procedure between 9, the transmission image information is received and the image data is stored in the buffer 6. This image data is encoded (compressed),
The decoding section 14 decodes (decompresses), expands it into a bit image for writing in the bit image storage area 10b of the image memory 10 in page units, and writes it.
Then, bits are developed at a predetermined resolution, and this is sent to the printer 15 for printing in page units.

Note that the signal according to the predetermined communication control procedure is a message for identifying each function of the terminal, instructing the selected state, and confirming the receivable state, as shown in FIG. Performing a pre-procedure (transmission / reception of a DIS signal, a DTC signal, etc.), an original procedure for transmitting a message, a post-message procedure, and a call recovery procedure.

Further, during memory reception such as proxy reception, compressed image data is stored in the memory receiving area 101 of the image data storage area 10a of the image memory 10, and the bit of the image memory 10 is recorded at the time of recording. Bits are expanded in the image storage area 10b.

During normal transmission, the transmission document is read by the scanner 13, encoded by the encoding unit 12, stored in the transmission area 102 of the image data storage area 10a of the image memory 10, and transmitted sequentially. . At the time of memory transmission, the data is also stored in the transmission area 102 and then the transmission operation is performed at a designated time.

During the polling transmission, when the calling facsimile device 19 calls the called facsimile device 1, the called facsimile device 1 scans the scanner 13.
Then, the transmission original is read in, encoded by the encoding unit 12, stored in the called transmission area 103 of the image data storage area 10a of the image memory 10, and sequentially transmitted.

Next, the registration processing of the speed dial in the facsimile apparatus 1 thus constructed will be described with reference to the flowchart of FIG. This process is started by turning on (operating) the speed dial registration key 11c provided on the operation unit 11. First, it is judged whether or not the abbreviated number (for example, 001 to 200) is input with the ten keys (S11), and if the abbreviated number is input (YES in S11), whether the telephone number to be registered has been input with the ten keys. If the telephone number is input (YES in S13), it is further determined whether the destination name is input (S15). If the destination name is entered (YES in S15), EEPR
The telephone number and the name of the other party are stored in the speed dial list provided in the predetermined area of the OM 8 in the form corresponding to the speed dial number (S17), and this processing is ended. The telephone number registered in the speed dial list is registered as the telephone number of the other party who performs facsimile transmission / reception. However, in the present embodiment, it is treated as the telephone number of the other party who may perform the polling transmission. .

Next, the main routine of the incoming call processing will be described with reference to the flowchart of FIG. This process is started when the power of the facsimile device 1 is turned on. When this process is started, first, the RAM 9
The telephone number memory 9a of the calling side is cleared (S20), and then it is judged whether or not a call signal is received (S2).
1) If the call signal is not received (N in S21)
O), the process returns to S21 and waits for an incoming call signal.
On the other hand, if the call signal is received in S21 (S2
If the calling side telephone number is not sent from the called exchange 17 (S23), the calling side telephone number is not sent (NO at S23). S
If the calling party telephone number is sent to 27, (S
23), the calling side telephone number is received and temporarily stored in the calling side telephone number memory 9a of the RAM 9 (S2).
5). Here, as the case where the telephone number of the calling side is not sent, for example, there is a case where the calling side refuses to disclose its own telephone number.

Then, it is judged whether or not the calling signal is stopped (S27), and if the calling signal is stopped, that is, if the caller interrupts the calling (YES in S27), the process returns to S20 to issue the call. The memory of the calling side telephone number memory 9a is cleared, and the incoming call signal is waited again (S2).
1). On the other hand, if the calling signal is not stopped in S27 (NO in S27), it is determined whether the calling signal is received a predetermined number of times (S29). Here, the predetermined number of calling signals means the function key 11 of the operation unit 11 in advance.
It is set by the operator as one of the start command signals for the automatic incoming call processing using the b and ten keys 11a.

If the calling signal has not been received a predetermined number of times in S29 (NO in S29), the process returns to 27 again. On the other hand, if the calling signal is received a predetermined number of times in S29 (YES in S29), it is determined whether or not the facsimile device 1 is in a receivable state (S31). Facsimile device 1
If it is ready to receive (YES in S31), the automatic incoming call process is executed (S39), and thereafter, the process returns to S21 and is in the incoming call waiting state of the call signal. Here, the state in which the facsimile device 1 is receivable means that the recording paper sensor 20 is not outputting a predetermined signal indicating that the recording paper is not attached to the printer 15 or the recording paper sensor 20 is in the predetermined signal. Even if is output, the image memory 10
Of the image data storage area 10a, there is a free space in the memory receiving area 101. In addition, automatic incoming call processing (S
39) will be described later.

On the other hand, if the facsimile apparatus 1 is in the unreceivable state in S31 (NO in S31), it is determined whether or not the polling transmission is on standby (S33). Here, the state in which the facsimile apparatus 1 is incapable of receiving means that a predetermined signal indicating that the recording paper 15b is not attached is output from the recording paper sensor 20 to the printer 15, and the image data storage area 10a of the image memory 10 is present. Of these, there is no space in the memory receiving area 101. The standby for polling transmission means that the polling transmission mode is stored in the mode memory 9b of the RAM 9. It should be noted that, even if the facsimile device 1 is in the polling transmission standby state, image information has been transmitted from the facsimile device 19 on the calling side as long as it can be received by the recording paper 15b or the memory receiving area 101. In that case, the image information can be received.

If polling transmission standby is not in effect in S33 (NO in S33), the facsimile machine 1 cannot receive or perform polling transmission, so an error message (error signal) is sent to the calling facsimile machine 19 (S4).
1) Then, the process returns to S20 and the calling side telephone number memory 9a
Is cleared, and the incoming call waiting state for the call signal is set (S2
1).

On the other hand, if the polling transmission is waiting in S33 (YES in S33), it is determined whether or not the calling side telephone number is stored in the calling side telephone number memory 9a (S).
35), if the calling side telephone number is not stored in the calling side telephone number memory 9a (NO in S35), an error message (error signal) is sent to the calling side facsimile device 19 (S41) and received. Notify the caller that you cannot. After that, the process returns to S21 to enter the waiting state for the incoming call signal. On the other hand, if the calling party telephone number is stored in the calling party telephone number memory 9a in S35 (YES in S35).
S), it is determined whether or not the calling party telephone number matches the telephone number registered in the speed dial list (S3).
7).

If the calling party telephone number does not match the telephone number registered in the speed dial list in S37 (S37).
No), the caller is a party who has no possibility of performing polling transmission, and therefore, it is considered that the image information is transmitted to the called facsimile machine 1. However, since the facsimile machine 1 is in the unreceivable state, it sends an error message (error signal) to the facsimile machine 19 on the calling side (S41) to inform the caller that it cannot receive the message. After that, the process returns to S20, the calling side telephone number memory 9a is cleared, and the incoming call waiting state of the calling signal is set (S21).

On the other hand, if the telephone number of the calling side matches with the telephone number registered in the speed dial list in S37 (YES in S37), the calling party is a party who may perform polling transmission. , Perform automatic incoming call processing (S
39), and then returning to S20, the calling side telephone number memory 9
Clear a and enter the waiting state for incoming call signals (S
21).

Next, the automatic incoming call process (S39) executed in the main routine of the incoming call process will be described with reference to the explanatory view showing the communication control procedure of FIG. 3 and the flowchart of FIG. Incidentally, this automatic incoming call process is a well-known process. When the automatic incoming call processing is started, first, the line is closed (S61), and various signals including the DIS signal (digital identification signal) are sent to the facsimile device 19 on the calling side (S63). This DIS signal is a signal indicating the transmission / reception capability of the called facsimile machine 1, and indicates, for example, that it is waiting for polling transmission. After confirming the contents of the DIS signal, the facsimile device 19 on the calling side sends a DTC signal (digital transmission command), which is a polling transmission command, or a DCS signal (digital signal) for normal transmission from the calling side to the called side. A command signal) is sent to the called facsimile machine 1.

The called facsimile machine 1 judges whether or not the DTC signal is received (S65), and if the DTC signal is received (YES in S65), polling transmission is executed (S67), and then the line is connected. Is released (S73), and the automatic incoming call process is terminated. On the other hand, if the called facsimile machine 1 does not receive the DTC signal (S65 returns N
O), it is determined whether or not the DCS signal is received (S6
9) If the DCS signal is received (YES in S69)
S), image information is received from the facsimile machine 1 on the calling side (S71), then the line is opened (S73), and the automatic incoming call process is terminated. On the other hand, if the DCS signal is not received in S69 (NO in S69), the line is opened (S73), and the automatic incoming call process is finished.

As described above, in exchanging signals in accordance with the normal communication control procedure, some communication abnormality (for example, the facsimile on the calling side even though the facsimile apparatus 1 on the called side cannot receive the signal) When the device 19 requests to receive a call (transmits a DCS signal), a DCN signal (line disconnection command) is transmitted,
Open the line.

In the automatic incoming call processing, the telephone fee is charged to the facsimile device 19 on the calling side for the period from the line being closed to the line being opened. According to the present embodiment described in detail above, when the calling party is registered in the speed dial list of the called facsimile device 1 as a facsimile transmission / reception partner (a partner who may perform polling transmission), If the facsimile machine 1 on the calling side is waiting for polling transmission, the line is closed by automatic incoming call processing and the caller requests polling transmission according to a normal communication control procedure, even if reception is impossible. Determine whether or not However, since this judgment is made after the line is closed, the caller will bear the telephone charge for that period, but in order to respect the will of the caller when performing polling transmission, the line will be closed and polled. The priority is to confirm the intention to send.

Therefore, in the prior art, the line is not closed even if it is in the waiting state for the polling and if the reception is impossible, there is an inconvenience that the caller desiring the polling transmission cannot perform the polling transmission. According to the above embodiment, such inconvenience is eliminated.

When the calling party is not registered in the speed dial list of the called side facsimile apparatus 1, the calling party is not the party who may perform the polling transmission and the image information is sent to the called side. It is considered that the data is transmitted to the facsimile machine 1. For this reason, if the called facsimile device 1 is in the unreceivable state, the called facsimile device 1 does not close the line regardless of whether or not it is waiting for polling transmission.

Therefore, there is no inconvenience that the caller is charged a telephone fee although the caller cannot send the image information to the called facsimile machine 1.
In addition, as another embodiment, S in FIG.
The processing after 33 may be changed as shown in FIG. That is, when the polling transmission is not waiting in S83 (S8
If NO in S85, the calling party telephone number is not stored in the calling party telephone number memory 9a in S85 (N in S85).
O), or if the calling telephone number stored in the calling telephone number memory 9a does not match the telephone number registered in the speed dial list (NO in S87), the above S
41 does not perform the error message sending processing, and
Without returning to 20, the process proceeds to S27, until the call signal is stopped, or the recording paper 15b is replenished, or the memory receiving area 101 of the image data storage area 10a becomes vacant, so that the image data Until reception becomes possible, S27, S29, S31, S83, S8
The processing of S5 and S87 may be repeatedly executed.

Needless to say, the present invention is not limited to the above-mentioned embodiments and can be carried out in various modes without departing from the technical scope of the present invention. For example, although polling transmission is taken as the called transmission in the above-described embodiment, confidential retrieval transmission, remote control transmission for taking out image data received in memory from a destination, etc. may be used. Here, the confidential retrieval transmission is registered in the ID sent from the facsimile device 19 on the calling side and each of one or a plurality of mailboxes provided in the called transmission area 103 of the image memory 10. It refers to collating with the retrieval ID, and if there is a match, the content stored in the mailbox with the matching ID is transmitted to the facsimile device 19 on the calling side. The remote control transmission means that the image data transmitted from the calling side facsimile device 19 is transferred to the image memory 10.
It means that the data is temporarily received by the called transmission area 103 of the memory, then the call is made from the outside, and the contents stored in the called transmission area 103 are transmitted to the calling side.

Further, in the above embodiment, the telephone number of the other party for facsimile transmission / reception is polled and transmitted (callee transmission).
However, in addition to the telephone number and the name of the other party, polling transmission (callee transmission) is possible, for example, in a form corresponding to the shortened number in the speed dial list. Whether or not there is a call is stored, and in S37 of FIG. 5, the automatic incoming call processing (line closing) of S39 is executed or the error message of S41 depending on the possibility of polling transmission (callee transmission) of the speed dial list. May be selected. In this case, the caller who has no possibility of performing polling transmission (call reception transmission) even if he / she sends / receives facsimile data, closes the line if polling transmission is not possible even if waiting for polling transmission. Since it is not linked, there is an effect that the telephone charge is not charged.

[0046]

As described above in detail, according to the facsimile apparatus of the present invention, when the caller is waiting for a called transmission, if the calling party is a party to whom the called transmission may be made, the intention of the called party. The effect of being able to respect is obtained.

That is, conventionally, even when the called transmission is on standby, in a certain case (for example, in the unreceivable state),
Since the line was not connected at all regardless of the caller, the caller had the inconvenience that the call transmission had to be tried many times. However, according to the facsimile apparatus of the present invention, The above-mentioned inconvenience is solved because the caller who may perform the transmission can perform the called transmission without being rejected while waiting for the called transmission.

Further, according to the facsimile apparatus of the present invention, when the caller is waiting to be transmitted and cannot receive the call, the telephone charge is charged unnecessarily when the caller is a party who is unlikely to send the call. It is possible to prevent such a situation from occurring and to respect the intention of the other party when there is a possibility of receiving the call.
