Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a facsimile server having a function of distributing received data to a client.
[0002]
[Prior art]
Recently, facsimile systems have spread in offices and the like, and play a useful role in data communication. Such a system is configured by connecting a facsimile server, a client, a mail server, and the like through a communication network such as a LAN, and the facsimile server executes various events such as a reception event and a transmission event described later. Can do.
[0003]
In the reception event, when image data is received through a public network or the Internet, a reception completion notification is distributed as a notification event to the client. In the transmission event, image data received from a client is transmitted to a facsimile machine connected to a public line network or the Internet. When the transmission is completed, a transmission completion notification is distributed to the client as a notification event.
[0004]
[Problems to be solved by the invention]
By the way, in the conventional facsimile server described above, when these events occur, they are executed if the target client is logged in to the facsimile server. However, when these are not logged in, these events are stored in the memory. When the corresponding client logs in, the event processing task reads the corresponding event from the memory and processes it.
However, since such processing is performed by a single event processing task, when there are a large number of events to be processed in the memory, the event processing takes time and is inefficient.
[0005]
The present invention has been made in view of the above circumstances, and an object thereof is to provide a facsimile server that can efficiently process an unprocessed event for a client when a target client logs in. .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, in the facsimile server according to claim 1 of the present invention, when an event occurs, control is performed with the CPU on the condition that the client to be notified of the event is not logged in. A facsimile server configured to store the generated event in the event queue as an unreported event by cooperating with the program, comprising a plurality of event processing tasks, and by cooperating with the CPU and the control program, When an unreported event for the client is stored in the event queue when the client logs in, multiple event processing tasks are run, and the notification processing for the unprocessed event is performed on those event processing tasks. I try to let them .
[0007]
Here, the event includes a reception event for distributing image data received through a public line network or the Internet to a client, and a transmission event for transmitting image data received from a client to a facsimile machine connected to the public line network or the Internet. , A notification event for delivering a reception or transmission completion notification to the target client upon completion of the reception event or the transmission event, a paper out notification event for notifying the target client of a paper out of paper, a document There is a network scan event or the like in which the image data is read and converted into image data, and the image data is sent to the target client.
[0008]
In the facsimile server according to claim 2, unreported events are stored as an event queue in a non-volatile memory such as a compact flash.
[0009]
In the facsimile server according to the third aspect, the plurality of event processing tasks process unreported events simultaneously or sequentially.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a main configuration of a facsimile server 1 according to the present invention. FIG. 2 is a diagram illustrating a configuration of a facsimile system including the facsimile server 1.
[0011]
The facsimile server 1 is connected to a telephone line L and is connected to a LAN (N1) as a communication network. The LAN (N1) has a client 2 constituted by a personal computer as shown in FIG. And a mail server 3 connected to the Internet N3.
[0012]
The facsimile server 1 can execute various events such as a reception event and a transmission event. In the reception event, when image data is received through the public line network (PSTN) N2 or the Internet N3, reception to the client 2 is completed. Deliver notifications as notification events. Further, in the transmission event, the image data received from the client 2 is transmitted to a facsimile machine connected to the public line network N2 or the Internet N3, and when the transmission is completed, a transmission completion notification is notified to the client 2 Deliver as.
[0013]
As shown in FIG. 1, the facsimile server 1 includes a CPU 10 that controls the following units, a RAM 11 composed of a nonvolatile memory such as a compact flash, a ROM 12 that stores a control program and the like, and image data from a document. Scanner 13 for reading and converting to image data, data received via telephone line L or LAN (N1), printer 14 for recording data read from scanner 13 on a predetermined recording paper, and connection to telephone line L NCU 15 for controlling, modem 16 for modulating / demodulating various signals necessary for facsimile communication, operation panel 17 including a liquid crystal screen and various operation keys, and image data for MH, MR, MMR for facsimile communication CODEC 18 that encodes and decodes the system and LAN (N1) And a LAN interface 19 to be connected in accordance with the standards such as theft.
[0014]
In this facsimile server 1, if the target client 2 is not logged in to the facsimile server 1 when each event described above occurs, these events are stored in the RAM 11 as an event queue. The event queue is configured as shown in FIG. 3, and the event queue 11A sequentially stores the event number, the date and time when the event occurred, the corresponding client, and the event type that occurred. When the corresponding client 2 logs in, the event processing tasks T1 to T3 (provided in the CPU 10) shown in FIG. 4 read and process the corresponding event from the event queue 11A.
[0015]
The basic operation of the facsimile server 1 including such processing will be described with reference to the flowcharts of FIGS. That is, as shown in FIG. 5, when each event occurs (100), the facsimile server 1 determines whether the target client 2 is logged in to the facsimile server 1 (101). The generated event is processed (102). On the other hand, if the target client 2 is not logged in to the facsimile server 1 (101), the generated event is stored in the event queue 11A (103). At this time, this event is set to unused tasks T1 to T3 among the event processing tasks T1 to T3 described above.
[0016]
As shown in FIG. 6, when the target client 2 logs in the facsimile server 1, the event stored in the event queue 11A is read out from the event queue 11A by the event processing tasks T1 to T3 described above. Execute (200-202). When a plurality of unprocessed events are stored in the event queue 11A, the unprocessed events are executed simultaneously or sequentially by the corresponding event processing tasks T1 to T3.
[0017]
【The invention's effect】
As can be understood from the above description, in the facsimile server according to claim 1 of the present invention, if there is an unprocessed event for the client, the unprocessed event is processed by a plurality of event processing tasks when the client logs in. Since the event is processed, an unprocessed event for the client can be efficiently processed when the target client logs in.
[0018]
In the facsimile server according to claim 2, since the unprocessed event is stored as an event queue in a non-volatile memory such as a compact flash, the unprocessed event is stored even when the power of the facsimile server is turned off. I can keep it.
[0019]
In the facsimile server according to the third aspect, since the plurality of event processing tasks process the unprocessed events simultaneously or sequentially, the unprocessed events can be processed efficiently.
