Abstract

PURPOSE:To decrease the required time at data transfer by processing a sub- task executed after call command in parallel with the processing of a main task. CONSTITUTION:In the sub-task, whether or not a main station of a caller side equipment is in use is judged with an execution start command, and when it is not in use, a telephone line connecting a transacted processing unit and a center is opened and the presence of a caller at the caller side equipment is discriminated. When a dial tone exists in the caller side equipment, the end of the sub-task is informed to a main task in a form of parameter. On the other hand, the main task awaits the operation of an execution key, judges the end of the sub-task by the parameter given from the sub-task and displays ''during dialing'' to a display 2. Then a selection number to call the center is oscillated according to a telephone number inputted and displays ''during talking'' to the display 2. Then the main task communicates with the center and when the data transfer transferring the inputted data to the center is finished and the communication is finished, the telephone line connected to the center is used and ''end of communication'' is displayed on the display device 2.

Description

Detailed Description of the Invention: fal Technical Field The present invention relates to a data transfer method using a telephone line of a communication device having automatic call origination and automatic call reception functions.

(bl Conventional technology and its drawbacks Communication devices with automatic calling and automatic receiving functions, such as facsimiles, use telephone lines to transfer data. In addition to the basic task (referred to as the "main task") performed by inputting the data to be transferred and inputting the telephone number of the other party's device as a selection signal, It is necessary to execute a task (hereinafter referred to as a "subtask") that determines whether data transfer is possible.

In the subtask, (11) Is the main phone of the calling device unused? (Determination is necessary only if the calling device is a parent-child phone, and is not necessary if it is not a parent-child phone) (2) Three items are determined: whether the calling device is not receiving a call (3) whether there is a dial tone on the calling device, and the call can only be made when these conditions are satisfied. ,
Generally, it takes 2 to 3 seconds.

However, in the conventional data transfer method, the data is transferred only after the execution of this task is completed, so there is a delay of 2 to 3 seconds after the transmission command is received, and the data is transferred. There is an inconvenience that the
Therefore, there was a problem in that the data transfer time became long.

(C1 Purpose of the Invention This invention was made to solve the above problem, and it reduces the time required for data transfer by performing the processing of the subtask that was being executed after the transmission command in parallel with the processing of the main task. The purpose is to provide a data transfer method that shortens the time required.

+d1 Structure and Effect of the Invention The present invention is a data transfer method for a communication device that can automatically make and receive calls using a telephone line, and the main task is to transfer input data to the other party's device. During processing, a subtask is executed to determine whether or not the originating device is in a state where data transfer is possible, and the determination result by this subtask is passed as a parameter during processing of the main task.

According to this invention, the main task and subtasks are processed in parallel, and the processing result of the subtask is passed as a parameter to the main task being processed.This causes a time delay between when a transmission command is issued and when the transmission is transmitted. Therefore, the time required for data transfer can be significantly reduced.

TELE EXAMPLE Below, a transaction processing apparatus will be described which is a communication device having automatic call origination and automatic call reception functions and is adapted to conduct transactions using an input medium such as a magnetic card.

FIG. 1 shows a schematic configuration of a transaction processing device, l is a microcomputer system, and this microcomputer system 1 is a central processing unit that performs calculations necessary to execute a control program necessary for transaction processing. 11
It has a known configuration consisting of a memory 12 for storing control programs necessary for transaction processing and information read from an input medium such as a card, and an interface 13. The interface 13 inputs a code signal generated from the input device 4, and outputs information to be displayed and printed by the display 2 and printer 3 as a code signal. The display 2 is for displaying the procedures required for each operation step by the customer as guidance information when making a transaction.
The printer 3 prints out the results of communication with the center, that is, the results of transactions, on a journal.

A modem 5 is connected to the interface 13, and a disconnector 6, a network controller 7, and a converter 8 are connected serially to the modem 5.
is connected.

On the other hand, since the transaction processing device and the center serving as the receiving device are connected via a telephone line, data transfer between the two is performed using the telephone line.

In the transaction processing device having such a configuration, a plurality of operation keys are arranged as shown in FIG. 2 on the data input device 4 provided for inputting data to be transferred.

Next, the operation of the transaction processing device will be explained. FIG. 3 is a flowchart showing the operation of the transaction processing device. Third
In the figure, steps 100 to 118 represent main tasks, and steps 200 to 205 represent subtasks. In step 100, "start key j" is displayed on the display 2, and in step 101, it is determined whether or not the start key has been input. If it is determined that the start key has been operated, the process proceeds to step 102; otherwise, the process proceeds to step 101. Return to again.

In step 102, a command is given to start execution of the subtask. Since subtasks are executed by interrupt control, after this command, the main task and subtasks are executed in parallel.

The subtask waits for an execution start command in step 200, and proceeds to step 201 if there is a start command.

In step 201, it is determined whether the telephone of the originating device is in use. As a result of the determination, if the telephone is not in use, the process proceeds to step 202. Note that step 201
This determination is executed only when the originating device has a parent/child telephone, and is omitted when the originating device does not have a parent/child telephone, and the process proceeds to the next step 202.

In step 202, it is determined whether or not the calling device is receiving an incoming call, and if not, the process advances to the next step 203.

In step 203, a telephone line connecting the transaction processing device and the center is opened, and in step 204, it is determined whether or not there is a dial tone on the calling side device.

If there is a dial tone on the calling side device, the process advances to step 205. In step 205, the main task is notified in the form of a parameter that the subtask has ended.

On the other hand, the main task is being executed in parallel while the subtasks are being executed, and in step 103 the display 2 displays ``data human power j'', and in step 104 the second
Wait for data input from the numeric keypad shown in the figure. After the numeric keypad is operated, the set key is operated to indicate the end of data input, so in step 105 it is determined whether or not the cent key has been operated. Step 10 if there is any operation
Proceed to step 6 and display the rt talk number J on the display 2.

In step 107, when the numeric keypad is operated again and the telephone number of the center is input, it is determined in step 108 whether or not the set key has been operated. If it is determined that the cent key has been operated, the process proceeds to step 109 and an "execute key" is displayed on the display 2. Further step 1
The process advances to step 10, waits for the execution key to be operated, and then advances to step 111. In step 111, the end of the subtask is determined based on the parameters passed from the subtask. If the subtask has been completed, the process advances to step 112 and displays "Dialing J" on the display 2. In step 113, a selected number for calling the center is called according to the telephone number entered manually in step 107, and further Proceeding to step 114, "Communicating" is displayed on the display 2. In step 115, the data transfer of communicating with the center and transmitting the input data to the center is completed, and when the communication is completed, the process proceeds to step 116, where the telephone line connected to the center is closed, and the process proceeds to step 117. ``Communication Ended'' is displayed on the display 2, and the process proceeds to step 118. In step 118, the printer 3 is activated, and the communication result, that is, the transaction result, is printed and typed out in a journal, and step 1 is used for the next transaction.
Return to 00.
