Abstract

PURPOSE:To enable an effective connection control of a line in a terminal equipment of a telephone in a building required for a transmission by transmitting a selection signal during a recalling at the same time interval as an operation time interval during and input of the selection signal. CONSTITUTION:Since the selection signal inputted by an operator and the time interval in the input as the selection signal and timer data are alternately stored in a prescribed area of a memory 11, the same selection signal is transmitted from a selection signal transmitting part 8 at the same time interval as the time when the operator inputs and fed out to a line 12 through an NCU9. When an end code is read, the transmission of the selection signal is stopped and a communication operation such as a telephone similar to the convention or a facsimile communication is performed. Accordingly, in the terminal of the telephone in the building or the like, even when a zero transmission is required, the time waiting for the response to an exchange is faithfully reproduced and an effectively intended remote party can been called out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device, and particularly to a communication device such as a telephone, a data communication device 4, or a facsimile device that makes a call by transmitting a selection signal.

[Prior Art] In conventional devices of this type, a selection signal such as a dial tone that is manually input by an operator using a numeric keypad or the like and sent at the same time is memorized, and the same selection signal can be returned without having to input the selection signal again. For example, in a facsimile machine, when a call is made and the line is in use, a memorized selection signal is generated at fixed time intervals. , a device is known that can automatically make multiple calls without repeating the calling operation many times by transmitting this to a line.

[Problems to be Solved by the Invention] However, in this type of conventional device, only the type (pattern) of the selection signal inputted from the operating means is stored, and when it is read out from the recording means and used, The time interval of the selection signal is controlled to a predetermined value.

Therefore, in terminals such as building telephones that need to send the next selection signal after confirming the exchange's response by "O call" etc., the transmission time interval of the selection signal when re-calling is shorter than the response time of the exchange. There was a problem where the line could not be connected. In addition, if the time interval for sending selection signals when re-calling is set longer than the response time of the exchange, it may take unnecessary time to re-call without using "0 transmission", or a reliable connection may not be possible. There was a drawback in not being able to do so.

[Means for Solving the Problems] In order to solve the following problems, in the present invention, a desired selection signal is input to a communication device that calls a partner station by transmitting a selection signal to a communication line. A means for storing a selection signal input from the operation means and an operation time interval at the time of inputting the selection signal is provided, and when calling the same partner station again, the contents of the storage means are adapted. A configuration is adopted in which the selection signal is transmitted at the same time interval as when the selection signal is inputted.

[Operation] According to the above configuration, the selection signal is transmitted at the same time interval as the operation time interval when the selection signal is input, so that it is possible to transmit the selection signal at the time of re-calling at the same time interval as the operation time interval when the selection signal is input. This also enables reliable line connection control.

[Example] The present invention will be described in detail below based on the example shown in the drawings.

Figure 1 shows an example of a device having a selection signal transmission function.
FIG. 2 is a block diagram showing the configuration of a facsimile device.

The facsimile device 1 is connected to a predetermined communication line 12 such as a telephone line via an NCU 9. An exchange 12a is connected to the opposite side of the four-wire 12. The NCU 9 switches the line 12 between the facsimile machine 1 and the handset (or telephone) 13 that does not have a dialing device, and
Performs operations such as holding loops. A selection signal sending section 8 is connected to the NCU 9, which generates a dial tone or dial pulse in response to operation of an input means such as a numeric keypad of the operation section 6. Furthermore, a modem 9 is used for modulating and demodulating procedure signals other than selection signals or image signals, etc.
is connected. Similar to the conventional apparatus, image reading of a document is performed by a reading section 4 configured using a CCD line sensor or the like, and the received image data is recorded by a recording section 5 consisting of a thermal printer or the like.

The operation of the entire apparatus is controlled by a control section 3 composed of a microcomputer or the like. The control unit 3 has a ROM
A memory 11 consisting of a RAM, etc. is connected, and this memory 11 stores image data read by the reading unit 4, image data to be recorded by the recording unit 5, control parameters for various types of control, etc. be remembered. Further, in this embodiment, the memory 11 is configured to be able to store the selection signal input from the operation unit 6 and the operation time interval at the time of inputting the selection signal.

The operation time intervals listed in L are totaled using a timer 14 composed of a counter element or the like. In addition, the operation when inputting a selection signal operation or transmitting or receiving operation is LC.
It is possible to monitor the information using a display unit 7 configured using a D or the like. Power necessary for the operation of the entire device is supplied from the power supply section 2.

Next, the operation of the above configuration will be explained. FIGS. 2 and 3 show the control procedure of the control section 3 during operation input and transmission of the 1 selection signal, respectively, and the illustrated procedure is stored in a predetermined area of the memory 11 as a program.

First, when inputting a selection signal, the hook state of the telephone 13 is checked in step S16 in FIG.

If the hook is on, it is determined that no call is to be made, and the process moves to step 32B, a standby state. On the other hand, if the hook is off, the process proceeds to step 517, where a press of the ten key for inputting a selection signal on the operation unit 6 is accepted. Then, the process moves to step 518, and the memory address N for storing the selection signal is set to an initial value. At the same time, the dial code corresponding to the pressed numeric keypad is stored in address N. Subsequently, in step S19, a selection signal corresponding to the pressed numeric keypad is generated as a dial tone or dial pulse in the selection value sending unit 8, and sent to the line 12 via the NCU 9.

Next, in step S20, the timer 14 is started,
Step S21. In S22, a routine similar to steps 516 and S17 for determining the state of the hook and the pressed state of the numeric keypad is performed.

If the numeric keypad is pressed here, the process moves to step S23,
Stop the timer 14.

Then, in step S24, the memory address N is incremented by 1, and the time measurement data of the timer 14 is stored in the address N.

Next, in step S25, the artless NQI is further increased, and the dial code corresponding to the ten key pressed in step S22 is stored in the address. Then, in step 326, a selection signal corresponding to the pressed ten key is sent out in the same manner as described above.

By repeating steps S21 to S326, a selection signal of a predetermined number of digits is transmitted, and when the handset is hooked on, the memory address N is re-transmitted in step S27.
is incremented by 1, a predetermined end code indicating the end of the selection signal is stored at that address, and the transition is made to the standby state 28.

The destination station is called by the selection signal sent out in the manner described above, but if the destination station is busy or if re-calling is to be performed by manual operation, the procedure shown in FIG. 3 is carried out. Manual re-calling is specified by operating a re-calling key provided on the operation unit 6. In the case of re-calling, first, in step S30 of FIG. 3, the address N of the selection signal storage area of the memory 11 is set to an initial value. Then step S1
3 reads the data at that address, and in step S32
to find out if it is the end code. If the read code is not an end code, the process moves to step S33, and a selection signal corresponding to the code is transmitted. Next, in step S34, the memory address N is incremented by 1, in step S35, the timer data stored in the memory stored at this address is read, and in step 336, the read timer data is set in the timer 14 to start timing. , waits for the time corresponding to the timer data to elapse. When the time of the timer data has elapsed, the memory address is incremented by 1 in step S37 and the process returns to step S31.

As described in connection with FIG. 2, the predetermined area of the memory 11 contains selection signals inputted by the operator such as selection signal, timer data, selection signal, timer data, and the time intervals at which the inputs are made alternately. Since it is stored in step 531-
By repeating step 337, the same selection signal is transmitted by the selection signal transmitter 8 at the same time interval as when inputted by the operator, and is transmitted to the line 12 via the NCU 9. When the end code is read out in step S32, the transmission of the selection signal is stopped and a predetermined communication operation such as conventional telephone or facsimile communication shown in step S38 is performed.

Therefore, according to the embodiment described below, even if a 0 call is required at a terminal such as a building telephone, the time spent waiting for a response from the exchange is faithfully reproduced when calling again, and the intended destination can be reliably called. becomes possible. In addition, when using a building telephone terminal for communication within the premises that does not require an O call, even if the selection signal is input at short time intervals, selection 48 will be played at the same time interval even when it is input. ,
The time required for making a call is shorter than that for making a zero call, and moreover, reliable connection control is possible.

Although an embodiment of a facsimile machine has been described above, the technology of the present invention is not limited to facsimile machines, but can be easily implemented in various data communication devices including telephones, personal computers, word processors, and the like. In the control shown in FIG. 2, an example is shown in which the selection signal is input from the operation unit 6, but the same control is also possible when the selection signal is input from the telephone 13 using the dial or numeric keypad of the telephone.

[Effects] As is clear from the above description, according to the present invention, in a communication device that calls a partner station by transmitting a selection signal to a communication line, an operating means for inputting a desired selection signal is provided. and means for recording the selection signal inputted from the operating means and the operation time interval at the time of inputting the selection signal, and when calling the same partner station again, the selection signal is recorded in accordance with the contents of the storage means. The structure is such that it is transmitted at the same time interval as when it is inputted, so even if it is a line terminal that requires a special pattern for the input of a selection signal or the transmission time interval, it is easy to operate. Therefore, it is possible to provide an excellent communication device that can perform a reliable re-calling operation without repeating the process.
