Abstract

PURPOSE:To contrive the simplification of the operation by holding a polling request till a specific picture data is stored when a specific picture data in response to a polling request is not stored in its own station. CONSTITUTION:When a polling request is given from an instructing station, a CPU 14 decides at first whether or not a specific picture data in response to a request is stored in a picture memory 12. When the specific picture data does not exist in the memory 12, the CPU 14 registers and stores a picture data name having a polling request and a dial number of the opposite station (instructing station) to a communication reservation table in a RAM 13. The CPU 14 stops the control operation to the request tentatively till the picture data in response to the polling request is stored in the picture memory 12 and applies control operation such as transmission/reception by other picture data. Thus, one polling request is enough and excess operation by the instructing station is saved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile communication method that recognizes a polling request from a partner station and transmits specific image data in response to the request.

[Conventional technology]

Conventionally, in such a method, as shown in FIG. 5, facsimile device A of the instruction station makes a polling request to facsimile devices @B and C of specific terminal stations to transmit specific image data. and the facsimile machine B,
If C has stored the requested specific image data, it transmits the image data to the facsimile H1iA, and if it has not stored the requested specific image data, it rejects the polling request. Was.

[Problems that Komei tries to solve]

However, in the above method, when specific image data requested for polling is not stored.

Since the terminal station rejects the above request, the operator at the instruction station has to repeat the same operation at a predetermined interval and make a polling request, which increases the time required to use the facsimile machine and makes the operation complicated. There was a problem with that.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a facsimile communication method that can simplify operations when a polling request is rejected.

[Means and effects for solving the problem] The present invention prevents the operator of the instruction station from repeating the same operation by holding the polling request until specific image data corresponding to the polling request is accumulated. However, the terminal station can transmit a specific image in response to the polling request to the instruction station.

〔Example〕

Embodiments of the present invention will be described in detail based on the drawings of FIGS. 1 to 4.

FIG. 1 is a configuration block diagram showing an embodiment for causing the facsimile device of the terminal station shown in FIG. 5 to perform the communication method according to the present invention. In the figure, reading device 11
reads the original document optically and converts it into image data, and the image data is stored in the image memory 12. R.A.
The M13 stores a transmission reservation table according to the present invention, and the transmission reservation table includes, as shown in FIG.
It is configured by registering the data name for which a polling request was made and the dial number of the destination. Central processing unit (hereinafter referred to as CPU)
That's what it means. ) 14 controls the communication control unit 16 based on the transmission reservation data when specific image data corresponding to the polling request is stored in the image memory 12. Through this control, the communication control unit 16 transmits the specific image data encoded by the encoding/decoding device 15! ! 17 to the instruction station. Note that when the communication control unit 16 receives encoded image data from another station, the encoding/decoding device 15 decodes the image data. Further, 18 is a printing device for printing image data, 19 is an operation instruction device for inputting operator instructions, and 20 is a disk device for auxiliary storage of image data.

Next, Figure 3 shows the operation of the facsimile machine shown in Figure 1.
This will be explained based on the flowchart shown in FIG. In Figure 3, when there is a polling request from the instruction station, the CPU
14 first determines whether specific image data corresponding to the above request is stored in the image memory 12 (step 101). If specific image data is stored, the communication controller 16 that encoded the image data transmits the encoded image data to the instruction station that has made the polling request (step 102).

Furthermore, when there is no specific image data in the memory 12,
The CPU 14 registers and holds the name of the image data requested for polling and the dial number of the destination (instruction station) in the communication reservation table in the RAM 13 (step 103).

Note that in the above registration, vacant areas in the communication reservation table are searched and the above areas are sequentially used. Next, CPU1
4 temporarily ends the control operation for the above request until the image data corresponding to the polling request is accumulated in the image memory 12, and performs control 1 for sending and receiving other image data.
Create lIvJ. Then, as shown in FIG. 4, both edge data are read by the reading device 11, and
2 (step 111,) CPLI
Step 14 determines whether the data name of the image data is registered in the transmission reservation table (step 112).
. If the data name is not registered here, the operator who inputs the image data from the operation instruction table v119 calls the destination in response to an instruction, such as inputting the dial number of the destination, and performs normal data transmission ( Step 113). Further, when the data name of the image data stored in the image memory is registered and held in the transmission reservation table, the dial number of the reservation destination is searched from the data name and the communication control unit 16 is controlled based on this dial number. After calling the reservation destination and detecting that the reservation destination is in a receivable state, the image data is transmitted (step 114). When the data transmission is completed, the data name and dial number for which transmission has been completed are deleted from the data in the transmission reservation table, and the control operation is ended.

Therefore, in the present invention, the data name of the image data and the dial number of the transmission destination are registered and held in the transmission reservation table until the specific image data corresponding to the polling request is stored in the image memory. Polling requests only need to be made once, eliminating unnecessary operations on the instruction station side.
In addition, the exclusive time of the facsimile machine at the time of polling request can be reduced.

In the present invention, a communication system has been described in which a polling request is made from an instruction station to each terminal station and the image data of the terminal station is transmitted, but the system is not limited to the above system. The method of the present application can also be used in a communication system in which a data transmission system is provided and data is transmitted in response to a polling request from a terminal station. In this case, the dial number registered in the reservation table of the instruction station corresponds to the telephone number of the terminal station that made the request. Furthermore, the method of the present application can also be used in data communication between terminal stations using facsimile machines without intervening an instruction station. Furthermore, the communication method of the present application allows data communication to be performed whether the parties are one to one, one to many, or many to many.

[Advantageous Effects of the Invention 1] As explained above, in the present invention, the polling request is held until the specific image data corresponding to the polling request is accumulated, and there is no need to issue another polling request. This simplifies the operation.
