Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus. 2. Description of the Related Art A general facsimile apparatus is configured so that an automatic reception mode in which an automatic reception operation is performed when an incoming call is received and a manual mode in which a telephone rings are selected, and is switched to the automatic reception mode. If a facsimile signal from the transmitting side that specifies facsimile transmission is not transmitted within a predetermined time even if there is an incoming call, the line is automatically disconnected and the system returns to the standby state (for example, See JP-A-60-66159). However, in small offices and ordinary homes,
One telephone line is also used as a facsimile machine and a telephone for talking. In this case, when the facsimile apparatus is set to the automatic reception mode, a person who calls simply to make a call only hears the answering sound of the facsimile apparatus even if a call is made, and the predetermined time elapses as described above. There was a problem that a call could not be made because the line was cut. In order to improve this point in recent years, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-51056,
If a facsimile signal is not transmitted within a predetermined time after an incoming call, a facsimile apparatus has been developed which makes a telephone call and enables a call to be made with a caller if the caller answers the call. . [0005] However, in this type of apparatus, the telephone line is switched to the telephone side simultaneously with the start of the telephone call. That is, when the telephone handset is picked up, the telephone line goes off-hook, and the telephone line is switched in a state where a closed loop cannot be formed between the telephone line and the telephone. Therefore, it is necessary to separately provide a means for holding the telephone line in a closed loop state from the start of the telephone call to the time when the called party picks up the handset in response to the call. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a feature that a response signal is generated in response to an incoming call in an automatic reception mode, and thereafter, a response signal is generated from a calling side. A facsimile apparatus for starting a telephone call while continuing the detection when the facsimile signal of the facsimile cannot be detected within a predetermined time, and line switching means for switching and connecting a telephone line to the telephone; Means for responding to the telephone call, means for detecting pickup of the handset of the telephone, and control means for controlling each of the means, wherein the control means is in an automatic reception mode. After controlling the line switching means in response to the incoming call and switching the telephone line to the facsimile apparatus side, the detection of the handset pick-up detection means and the operation of the operation means Control is performed so that the telephone line is switched to the telephone side on the condition that the detection is performed. In this configuration, the telephone line is switched from the facsimile apparatus to the telephone on the condition that the telephone handset is picked up. An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of a facsimile apparatus. (1) is a control circuit for controlling the entire facsimile apparatus, which is constituted by a microprocessor, and in accordance with a program in a program memory (2) in which a processing program is stored. Each part is controlled. The control circuit (1) also performs signal processing of the read transmission original data and processing of the received signal. (3) a reading unit that optically reads a transmission original, converts the read black-and-white data into an electric signal, and supplies the electric signal to the control circuit (1);
It is composed of a lens mechanism, a lighting mechanism, an image sensor and the like. A recording unit (4) drives a recording head such as a thermal head under the control of the control circuit (1) based on the received signal to perform printing, and is composed of a recording paper and a recording paper transport mechanism and a recording head. A data memory (5) stores original data read by the reading unit (3), data subjected to signal processing, and the like. Data writing and reading are controlled by the control circuit (1). Reference numeral (6) denotes a keyboard including a transmission key, a reception key, a mode key, and a numeric keypad. The control circuit (1) which receives a key signal performs control in accordance with a program in a program memory (2) according to the key signal. (7) Telephone (L) on telephone line (L)
And a line switching circuit for switching and connecting the control circuit (1) of the facsimile apparatus and a well-known MBB (Make Befo).
re Break) and a transfer relay, and the switching is controlled by the control circuit (1). (9) is a signal generation circuit for generating a telephone call signal. The generated call signal is amplified by a speaker (10) and sent out to a telephone line (L). Next, the operation of the present invention having the above configuration will be described with reference to the flowchart of FIG. First, in the standby state, the control circuit (1)
In step (S1), whether or not there is an incoming call is constantly monitored. If there is an incoming call, it is determined in step (S2) whether the mode is the automatic reception mode or the manual mode. If the manual mode is set, the control circuit (1) controls the line switching circuit (7) to switch the telephone (8) to connect to the telephone line (L). 8) The bell rings to notify the incoming call. If you answer the call and pick up the handset, you can talk to the caller. Control circuit (1) when the call ends and the handset goes on-hook
Returns to the standby state from step (S15). However, if the caller informs the facsimile apparatus that he / she wants to send the call, he operates the reception key of the keyboard (6), and the control circuit (1) that detects the reception key signal controls the line switching circuit (7). After the facsimile apparatus is switched from the telephone (8) to the telephone line (L), a predetermined communication procedure is performed to record the reception. Thus, manual reception can be performed. On the other hand, if the facsimile apparatus has been set to the automatic reception mode when there is an incoming call, the control circuit (1) proceeds to step (S3) and responds (CED signal).
To the telephone line (L) to inform the caller. Therefore, if the caller who hears this response tone tries to transmit the original by using the facsimile apparatus, the transmitter operates the transmission key to start transmission, and a predetermined facsimile signal is transmitted. The receiving facsimile apparatus checks whether or not the facsimile signal has been transmitted in step (S4) after the transmission of the response sound. If the facsimile signal is transmitted as described above, the facsimile signal is transmitted. Upon detection, the process proceeds to step (S5) to enter the automatic reception state and record reception. However, if the caller has just made a call to make a call, there is no facsimile signal transmitted, so it is determined in step (S7) whether or not 15 seconds have elapsed. In this case, since no facsimile signal has been transmitted even after 15 seconds have elapsed, the control circuit (1) proceeds to step (S8) to drive the call signal generation circuit (9), and the speaker (10)
And informs the called party of the telephone call and sends a call signal to the telephone line (L) to notify the caller that he is calling. Then, if the person on the receiving side who notices the telephone call picks up the handset and operates a predetermined button of the keyboard (6), the control circuit (1) controls the line switching circuit (7) and connects the telephone (8) to the telephone line ( Since connection is made to L), a call can be made with the caller. However, if the called party does not answer the telephone call within 35 seconds, the control circuit (1) stops the call signal in step (S11), disconnects the telephone line, and returns to the standby state. .
Thus, even if a call is made and a response sound from the facsimile apparatus is heard, a telephone call is made if the user waits 15 seconds, and a telephone call can be made. Next, the sender attempts to perform facsimile transmission and, after listening to the CED signal from the receiving side, sets the original well and fails to select the transmission mode. When the button is operated, the facsimile machine on the receiving side is making a telephone call, but during that time the facsimile signal is detected in step (S4), so if a facsimile signal is transmitted, the flow proceeds to step (S5). The receiving state is set. That is, 1
If the transmission button is operated during 5 seconds to 35 seconds, the reception state is set. In the above description, the telephone call is made by monitoring the elapse of time. However, the present invention is not limited to this. For example, as shown in the flowchart of FIG. 3, transmission of DIS or NSF transmitted after the CED signal is performed. The number of times may be counted, and a telephone call may be made when the number of transmissions reaches a preset number. At this time, it is preferable that the number of times is set by the keyboard (6), and the number of times can be changed to two or three depending on the use condition. According to the present invention, after receiving an incoming call in the automatic reception mode, the called party picks up the telephone handset in response to the telephone call, and subsequently operates the operating means (telephone button). By doing so, the telephone line is switched to the telephone line for the first time. That is, since the telephone is in an off-hook state and the telephone can switch the telephone line to the telephone after the telephone can maintain the closed loop with the telephone line, the configuration for separately maintaining the closed loop is unnecessary, and the circuit is not required. Can be simplified.
