Abstract

PURPOSE:To attain transmission reception of a data by the data transmitter- receiver even when no automatic reception mode is set in the unattended transmitter-receiver. CONSTITUTION:Upon the receipt of an incoming call from a communication line 5, an incoming call detection circuit 6 starts a reception control circuit 7. The reception control circuit 7 references mode information from a reception mode memory 9 to discriminate which reception mode is set. When the reception control circuit 7 discriminates it that the non-standard reception mode is set, the reception control circuit 7 refers to the timer information from a timer 8 to discriminate whether or not an incoming call comes consecutively. When the reception control circuit 7 discriminates it that the incoming call comes continuously, the reception control circuit 7 starts a data reception circuit 1 to implement actual reception processing.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transmitting/receiving device, and more particularly to an automatic data receiving system in a data transmitting/receiving device using a telephone line such as a facsimile machine.

0002

2. Description of the Related Art Conventionally, this type of data transmitting/receiving apparatus has an automatic reception mode and a non-automatic reception mode as data reception modes. If the automatic reception mode is set, data will be automatically received; if the automatic reception mode is not set, the system will be in a non-automatic reception mode, and data reception will be performed manually.

[0003] In such a conventional data transmitting/receiving device,
Manual operation was required to receive data when automatic reception mode was not set, so if automatic reception mode was not set in an unattended situation such as at night,
There was a problem in that it was impossible to send and receive data.

0004

[Object of the Invention] The present invention has been made in order to eliminate the problems of the conventional ones as described above, and it is possible to send and receive data even when the automatic reception mode is not set in an unattended situation. The purpose is to provide a data transmitting and receiving device that can transmit and receive data.

[0005]

SUMMARY OF THE INVENTION A data transmitting/receiving device according to the present invention is a data transmitting/receiving device that automatically receives data when an automatic receiving mode is set. The present invention is characterized in that it is provided with a determination means for determining whether the call is continuous, and a control means for controlling automatic reception of the data when the determination means determines that the call is continuous.

[0006]

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, data receiving circuit 1 receives data from communication line 5 when activated by reception control circuit 7 . The data receiving circuit 1 sends the received data to the received data output circuit 2. Received data output circuit 2
outputs the received data to the outside by printing or displaying it. The data transmission circuit 3 transmits data input from the transmission data input circuit 4 to the communication line 5.

When the incoming call detection circuit 6 detects an incoming call on the communication line 5, it activates the reception control circuit 7. When activated by the incoming call detection circuit 6, the reception control circuit 7 refers to the timer information from the timer 8, the mode information from the reception mode memory 9, and the operation information from the reception operation switch 10, and if necessary, Start up the data receiving circuit 1.

[0009] The timer 8 measures time according to instructions from the reception control circuit 7, and outputs the time period during which incoming calls are continuous to the reception control circuit 7 as timer information. Receive mode memory 9
holds the reception mode set by the reception mode setting switch 11, and outputs the reception mode to the reception control circuit 7 as mode information. The reception operation switch 10 outputs a signal for instructing reception from the outside to the reception control circuit 7 as operation information. When a reception mode is externally set, the reception mode setting switch 11 outputs the reception mode to the reception mode memory 9. Here, the reception modes include an automatic reception mode in which data is automatically received, a non-automatic reception mode in which data reception is performed manually, and a semi-non-automatic reception mode in which data is automatically received if continuous incoming calls are detected. There is a mode.

FIG. 2 is a flowchart showing the operation of one embodiment of the present invention. The operation of one embodiment of the present invention will be explained using FIGS. 1 and 2. FIG. If the data transmitting/receiving device is not performing any special processing, it is in a normal state (
Figure 2 step 25). In this state, when the incoming call detection circuit 6 detects an incoming call on the communication line 5 (step 20 in FIG. 2), the data transmitting/receiving device enters a series of reception processing. That is, when the reception control circuit 7 is activated by the incoming call detection circuit 6,
Referring to the mode information from the reception mode memory 9, it is determined which reception mode is set (step 21 in FIG. 2).

When the reception control circuit 7 determines that the non-automatic reception mode is set, it refers to the operation information from the reception operation switch 10 and determines whether a manual reception operation has been performed (step 2 in FIG. 22). Receiving operation switch 10
If a manual reception operation has been performed, the reception control circuit 7 activates the data reception circuit 1 to perform actual reception processing (step 24 in FIG. 2). On the other hand, if no manual reception operation has been performed with the reception operation switch 10, the reception control circuit 7 determines whether or not there is still an incoming call (step 23 in FIG. 2). If the call is still incoming, the process waits for a manual reception operation, and the reception control circuit 7 refers to the operation information from the reception operation switch 10 to determine whether or not a manual reception operation has been performed (step 22 in FIG. 2). The process of determining whether a call is incoming (step 23 in FIG. 2) is repeated. If the call is no longer being received, the reception control circuit 7 returns to the normal state (step 25 in FIG. 2).

When the reception control circuit 7 determines that the automatic reception mode is set, it immediately activates the data reception circuit 1 to perform actual reception processing (step 24 in FIG. 2). When this reception process is completed, the reception control circuit 7
returns to the normal state (step 25 in FIG. 2).

Further, when the reception control circuit 7 determines that the semi-non-automatic reception mode is set, it refers to timer information from the timer 8 and determines whether or not calls are being received continuously ( Figure 2 step 26). That is, the reception control circuit 7 determines from the timer information whether or not calls have been received continuously for a preset predetermined period of time (approximately one minute). If the incoming calls are continued for a predetermined period of time, the reception control circuit 7 activates the data reception circuit 1 to perform actual reception processing (step 24 in FIG. 2). On the other hand, if it is not determined that calls are being received continuously, the reception control circuit 7 determines whether or not calls are still being received (step 27 in FIG. 2). If the call is still incoming, the reception control circuit 7 again refers to the timer information from the timer 8 to determine whether or not the call is being received continuously (step 26 in FIG. 2) and to determine whether the call is incoming. (Figure 2 step 27)
Repeat. If the call is no longer being received, the reception control circuit 7 returns to the normal state (step 25 in FIG. 2).

[0014] Through the processing operations described above, unless the non-automatic reception mode is intentionally set, data can be sent and received by making a call for one minute or more in the worst case. Also, even if you do not set the automatic reception mode by mistake,
If the mode is initially set to semi-non-automatic reception mode, data can be sent and received in unattended situations such as at night even if automatic reception mode is not set.

As described above, when the semi-non-automatic reception mode is set, when the reception control circuit 7 determines that an incoming call on the communication line 5 is a continuous incoming call, the data reception circuit 1 is activated to automatically receive data. By controlling in this manner, automatic reception of data becomes possible unless the non-automatic reception mode is intentionally set. Therefore, without impairing the functions of the conventional data transmitting and receiving device, it is possible to transmit and receive data even when the device is unattended and the automatic reception mode is not set.

[0016] In one embodiment of the present invention, it is possible to set three reception modes, that is, an automatic reception mode, a non-automatic reception mode, and a semi-non-automatic reception mode. When data is detected, it automatically receives data, but it is possible to set two reception modes, automatic reception mode and non-automatic reception mode, and when continuous incoming calls are detected when non-automatic reception mode is set. Data may be automatically received, but the present invention is not limited to this.

[0017]

As explained above, according to the present invention, when an incoming call detected when the automatic reception mode is not set is determined to be a continuous incoming call, data is automatically received. In this case, data can be sent and received even if the automatic reception mode is not set.
