Description

Description: TECHNICAL FIELD The present invention relates to a facsimile machine. 2. Description of the Related Art Conventionally, facsimile apparatuses have been widely used as apparatuses capable of transmitting image information such as figures and characters to desired parties. Such a facsimile apparatus has a function called polling reception. The polling reception means that, for example, a user sets a document on a facsimile machine at home (hereinafter, referred to as “home device”) before going out, and moves from a facsimile machine at home (hereinafter, “home device”) to a home device. By performing remote control on the document, the set document can be transmitted and received by the destination device. Problems to be Solved by the Invention However, since the polling reception uses a specific facsimile signal as a remote control signal for remotely controlling a home device from a destination device, the same function is provided to both devices that perform transmission and reception. It had to be prepared.
In other words, it was not a function that could be achieved from almost any device on the go. Further, in the polling reception, only a document set in a home device in advance can be taken out to a destination device, and a further use has been desired. SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus capable of transmitting image information stored from almost all facsimile apparatuses at a destination by remote control from the facsimile apparatus at the destination. Means for Solving the Problems In order to solve the above-mentioned conventional problems, a facsimile apparatus of the present invention comprises an image signal receiving means for receiving an image signal transmitted through a line, and storing the received image signal. Image signal storage means, remote signal detection means for detecting a DTMF signal transmitted over the line for remote control, and called side information for detecting a called side information signal transmitted over the line. Signal detection means, image signal transmission means for transmitting the image signal stored in the image signal storage means to the telephone line, and image signal transmission standby when a DTMF signal transmitted through the line is detected by the remote control signal detection means. Control means for controlling the image signal stored in the image signal storage means to be transmitted to the telephone line by the image signal transmission means when the called information signal detection means detects the called information signal. And Operation With this configuration, most of the facsimile machines detect a DTMF signal that can be transmitted as a remote control signal, so that remote control can be performed even from most of the facsimile machines on the go, and the image signal received in the absence can be obtained. Embodiment that can be taken out from a destination One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a main part of a facsimile apparatus according to one embodiment of the present invention. In FIG. 1, 1 is a telephone line, 2 is an incoming call detecting means for detecting an incoming signal coming from the telephone line 1, 3 is a line closing means for connecting the telephone line 1 to the apparatus, Is an image signal receiving means for receiving an image signal sent from the caller, 5 is an image signal storage means for storing the received image signal, 6 is an interface circuit with the telephone line 1, and 7 is an image signal from the caller. Remote control signal detecting means for detecting a remote control signal, 8 is an image signal transmitting means for transmitting a stored image signal, and 9 is control means for controlling the entire apparatus, which is constituted by a microcomputer. Reference numeral 10 denotes a called-side information signal detecting means for detecting and receiving a called-side information signal transmitted from the receiving-side facsimile machine. In this embodiment, a dial signal (DTMF signal: dual tone multi-frequency signal) of a push-button telephone is used as a remote control signal from a caller. Even if the facsimile apparatus is not connected to a telephone, a general facsimile apparatus is provided with a button for transmitting a DTMF signal to connect a line. The operation of the facsimile apparatus configured as described above will be described below with reference to the flowchart shown in FIG. First, normal image signal reception will be described. When an incoming signal arrives from the telephone line 1, the signal is detected by the incoming detection means 2 (step a), and the detection signal is input to the input terminal P1 of the control means 9. In response to this, the control means 9 sends a control signal from the output terminal P2 to the line closing means 3 to control the line closing means to be in the ON state to close the telephone line 1, thereby connecting the apparatus to the telephone line 1 (Step b). Thereafter, the control means 9 controls the image signal receiving means 4 to the operating state by the output terminal P4, receives the image signal sent from the calling side via the interface circuit 6, records it on the recording paper, It is stored in the image signal storage means 5 (step d). The image signal is stored in the image signal storage unit 5 by controlling the image signal storage unit 5 from the output terminal W of the control unit 9 to a write state, and sequentially specifying a predetermined address from a predetermined address by a signal output from the output terminal A. I will remember. When the reception of the image signal is finished in step e, the end signal is sent from the image signal receiving means 4 to the input terminal of the control means 9.
Input to P5. When receiving the end signal, the control means 9 controls the line closing means 3 to be turned off from the output terminal P2 to open the telephone line, and stores the final address of the image signal storage means 5 in an internal register. (Step f). By the above operation, the image signal from the calling side is recorded on the recording paper and stored. Next, a case where the user retrieves the stored image signal from the destination by remote control will be described. A user calls this apparatus from a telephone attached to a facsimile apparatus installed in an office such as a destination. As a result, when an incoming signal arrives from the telephone line 1, the incoming detecting means 2
(Step a), and the detection signal is sent to the control means 9.
Is input to the input terminal P1. In response to this, the control means 9 sends a control signal from the output terminal P2 to the line closing means 3 to control the line closing means to be in the ON state to close the telephone line 1, thereby connecting the apparatus to the telephone line 1 (Step b). Here, when the user transmits a DTMF signal to the line by operating a push button of the telephone as a remote control signal, the DTMF signal is detected by the remote control signal detecting means 7 through the interface circuit 6 and shifts from step c to step g. Then, the detection signal is applied to the input terminal P3 of the control means 9, and in response to this, the control means 9 enters the image signal transmission standby state. Here, when the user operates the receive button of the facsimile apparatus, the called side information signal is sent out to the telephone line, and in step h, the signal is transmitted to the called side information signal detecting means 10 through the interface circuit 6 of the present apparatus. The detection signal is received and detected by the input terminal P7 of the control means 9.
Is applied to In response to this, the control means 9 sets the output terminal
The image signal transmitting means 8 is controlled to the operating state by P6, and the image signal storing means 5 is controlled to the reading state by the output terminal R, so that the image signal stored from a predetermined address of the image signal storing means 5 is transferred to the interface circuit 6. Via the telephone line 1 (step i). Therefore, the contents of the image information received in the answering machine by the facsimile machine installed at the destination can be known. here,
When the address output from the output terminal A becomes the same as the final address stored in the internal register, the control means 9 determines that the transmission of the image signal has been completed, and proceeds from step j to step k. Line closing means 3 from P2
Is turned off to release the telephone line 1 and wait for the next incoming call. As described above, the present invention provides an image signal receiving unit for receiving an image signal transmitted through a line, an image signal storage unit for storing the received image signal, and a line for performing remote control.
