And a communication processing unit 5 for performing communication processing such as reception, decompression, recording, reading of a document, compression, and transmission. [0003] When a call is retransmitted when the transmission destination is busy or absent, information is temporarily stored in a memory (in some cases, the information is already stored), and after a predetermined time, redialing is attempted a plurality of times. Have been. In this recall method,
Regardless of the other party's situation, the incoming call probability is the same every time, and when transmitting to a communication destination with a high use rate, the incoming call probability is low, so that a recall is repeated. [0004] In the above-mentioned conventional technology, the more the transmission is made to the destination that is used at a high rate,
The probability of receiving an incoming call is low, and a situation where re-calling is repeated is likely to occur. Also, as shown in FIG. 4 (a), since the transmitter is all busy during the repetition of the re-calling, it is impossible to receive from other equipment or use the other equipment by itself during that time. There was a problem that many were made. The present invention is to solve the above-mentioned problem in the prior art by combining with a waiting function which is an additional function of the line connection unit, and releases the line by a busy signal from the line connection unit. Queuing function to increase the utilization rate by making the device available until the ringer (busy release signal) arrives, and to enable communication to the destination if a ringback tone is received And a facsimile machine with the same.

If the signal input from the switching means 15 is a ring back tone, the transmission which has been on standby is started. That. With this configuration, in the facsimile apparatus with a waiting function, if the call-disabled detecting means 12 detects that the call cannot be received at the time of transmission by dialing, then the standby-instructing means 14 issues a standby instruction. A signal is output, and the line connection means 11 is
To notify the transmission standby to open the line, switch the output destination of the switching unit 15, and input the signal from the line connection unit 11 to the transmission / reception signal detection unit 16 via the switching unit 15; (Transmittable detection means 16a
) When the ringback tone is detected, the transmission that has been on standby is started. If the signal input to the transmission / reception signal detection means 16 is (the called signal detection means 1
If the called signal is detected (at 6b), reception is started. In the following embodiments of the present invention, a case will be described in which a standby mode setting key which is manually operated is provided. FIG. 2 is a diagram showing the configuration of the apparatus in one embodiment. Here, reference numeral 21 denotes an exchange (PBX) functioning as a line connection means, which has a standby function, and sends a busy tone signal when detecting the busy state of the destination apparatus, and informs the transmission apparatus of the fact. If there is a standby notification (input of a standby instruction signal) from the transmission source device, the line with the transmission source device is closed, and the system waits until the destination device is released from busy, detects the release, and transmits. The line with the original device (facsimile device 20) is connected and called. Reference numeral 22 denotes a dial unit in the facsimile machine 20, which can input a destination number and automatically performs redialing within a predetermined time. Reference numeral 23 denotes a standby mode setting key on an operation unit (not shown) of the facsimile machine 20, which can manually issue a standby command. Reference numeral 24 denotes a busy tone detecting unit serving as an inability to detect incoming call, and outputs a signal when a busy tone signal from the exchange 21 is detected. Reference numeral 25 denotes a standby instruction unit which issues a standby notification when the standby mode setting key 23 is pressed and the busy tone detection unit 24 outputs a signal. Reference numeral 25a denotes a coincidence detection unit, which outputs a signal when the standby mode is set to ON and a busy tone detection signal is input. 2
Reference numeral 5b denotes a standby instruction output unit which is activated by the coincidence detection signal and outputs a standby instruction signal to the exchange 21 and the switching unit 26 (described later) to notify the standby. Reference numeral 26 denotes a switching unit which outputs to any detection unit of the transmission / reception signal detection unit 27 (described later) based on signals from the busy tone detection unit 24 and the standby instruction output unit 25b and a dial (or redial) signal. Or
An output destination of a signal from the exchange 21 is selected. Reference numeral 26a denotes a No. 1 switch comprising an on / off switch, which is turned on by a dial (or redial) signal and turned off by a busy tone detection signal. When the No. 1 switch 26a is turned on, the transmission / reception signal detection unit 27
The ringback tone detector 27b (described later) of the exchange 2
1 is transmitted. Reference numeral 26b designates an N which is an on / off switch.
o.2 A change-over switch that is turned off by a dial (or redial) signal and turned on by a standby instruction signal. When the No. 2 changeover switch 26b is turned on, a signal from the exchange 21 is transmitted to a ringer detection unit 27a (described later) of the transmission / reception signal detection unit 27. In the switching unit 26, when dialing, the exchange 21 is switched via a No. 1 switch 26a.
To the ringback tone detector 27b so that a ringback tone can be detected. Reference numeral 27 denotes a transmission / reception signal detector, which determines whether the signal from the switching unit 26 is a ringback tone. It identifies whether the signal is a called signal, and outputs a signal to the transmitting unit 28a or the receiving unit 28b. Reference numeral 27a denotes a ringer detecting unit,
1 is detected. Reference numeral 27b denotes a ring back tone detecting unit which checks whether the signal input via the switching unit 26 is a ring back tone, and outputs a signal to a transmitting unit 28a (described later) of the communication unit 28 if the signal is a ring back tone. , Transfer to transmission. Reference numeral 27c denotes a called signal detection unit which checks whether the signal input via the switching unit 26 is a called signal. If the signal is a called signal, the receiving unit 28b of the communication unit 28
(Described later), and shift to reception. Reference numeral 28 denotes a communication unit which performs communication processing such as reception, decompression, recording, reading of a document, compression, and transmission via the line connection unit 21. Reference numeral 28a denotes a transmission unit which executes a transmission protocol and a transmission process, executes a transmission protocol when receiving a ringback tone detection signal, connects a line, and executes necessary transmission. Reference numeral 28b denotes a receiving unit for executing a receiving protocol and a receiving process. Upon receiving the called signal detection signal, the receiving unit executes the receiving protocol, connects the line, and receives the transmitted communication contents. As a result, the detectable state of the ringback tone in the transmission / reception signal detection section 27 changes according to the operation of the switching section 26, and when dialing, the No. 1 switch 26a of the switching section 26 becomes conductive and the exchange 21 to ringback tone detector 27b
, And a ringback tone can be detected. When the busy tone is detected, the No. 1 changeover switch 26a is turned off by the busy tone detection signal, and the ring back tone cannot be detected. Thereafter, when the standby mode is set and the standby instruction signal is output, the No. 2 switch 26b of the switching unit 26 is turned on, and the ringback tone detecting unit 27 is transmitted from the exchange 21 via the ringer detecting unit 27a.
b and transmission to the called signal detection unit 27c,
By passing through the ringer detector 27a, the ringback tone can be detected again. When the transmission is to be executed by the embodiment configured as described above, the communication is performed according to the procedure shown in FIG. First, when the standby mode setting key 23 is pressed to set the standby mode, and when a transmission instruction key (not shown) is pressed to instruct transmission, it is checked whether a busy tone signal has been sent from the exchange 21 (ST1).
If no busy tone signal is detected,
It is possible to conduct to the ringback tone detection unit 27b via the No. 1 changeover switch 26a, confirm a ringback tone described later (ST6), and shift to transmission (ST7). However, when the busy tone signal is detected and N
o.1 If the changeover switch 26a is off, it is checked whether the standby mode setting key 23 has been pressed (ST
2). If the standby mode setting key 23 has not been pressed, a busy display is performed on a display panel (not shown) (ST
3). If the standby mode setting key 23 is depressed, the coincidence detection unit 25a that has input the standby mode ON signal and the busy tone detection signal has the standby instruction output unit 25.
b, the standby instruction signal output unit 25b is activated by the instruction and outputs a standby instruction signal to the exchange 21 to wait until a ringback tone from the destination device is detected (ST4). In the exchange 21, the connection procedure is repeated until communication with the destination device becomes possible (ringer detection) (ST5). When the switchboard 21 detects the ringer, it notifies the transmission / reception signal detection unit 27 via the No. 2 switch 26b of the facsimile machine 20. Transmission / reception signal detection unit 27
Then, the ringer detecting section 27a transmits the signal transmitted from the exchange 21 to the ringback tone detecting section 27b or the called signal detecting section 27c. Then, when the ringback tone detecting section 27b detects the ringback tone (ST6), it issues a transmission instruction to the transmitting section 28a and sends the transmitting section 28a.
8a starts transmission (ST7). If the ringback tone is not detected and the called signal detector 27c detects the called signal (S
T8) The receiving unit 28a issues a receiving instruction to the receiving unit 28a.
(ST9). As described above, in the embodiment, conventionally, FIG.
If the dial signal is busy after sending the signal, redialing is repeated after the busy time δt has elapsed, and transmission can be performed if the ringer & ringback tone is detected within the specified number of times. If it is busy, it will not be delivered, but if the standby mode setting key 23 in the embodiment is pressed down, as shown in FIG. When the ringer & ringback tone is detected, transmission can be performed at the standby state. In this standby state, if there is a reception from another facsimile machine, the reception can be immediately shifted to the reception. Therefore, when the destination device cannot receive a call, it is possible to avoid making unnecessary calls, avoiding a non-reachable state, and without creating an unreceivable opportunity. At the same time, it is possible to improve the probability of arrival at a destination having a high utilization rate. In the standby state, reception becomes possible, and the probability of arrival of the transmission source device can be improved. Furthermore, since the standby mode setting key 23 is operated to determine whether or not to enter the standby state, if it is not necessary, the operation is not performed when the specified number of recalls is reached, as before. It can be cut to reach and can be used flexibly. As described above, in the facsimile apparatus with a waiting function according to the present invention, when the call-disability detecting means 12 detects that a call cannot be received at the time of dial-out transmission, the standby-instruction means 14 thereafter issues a standby instruction. A signal is output, the line connection means 11 is notified of transmission standby, the line is opened, the output destination of the switching means 15 is switched, and the signal from the line connection means 11 is transmitted and received via the switching means 15 to the transmission / reception signal detection means. 16 and if the input signal is a ringback tone, it is possible to start the transmission which has been waiting, so that "non-delivery"
The state can be avoided, reception from another device can be received, and the utilization rate of the own device with respect to another device can be increased, so that the reception rate can be improved in both transmission and reception.
