Among them, for example, it is known that data can be communicated by connecting a short distance between two terminals or the like by a wireless communication channel using a medium that can be realized at a low price such as infrared rays, has low power consumption, and is easy to downsize the device. ing.

[0003] Particularly, it is suitable for data communication of a portable terminal such as a mobile terminal, and is increasingly used.

[0004] Further, there has been proposed a method of connecting two distant buildings with a wireless communication channel to transmit data.

[0005] In such a case, the two terminals connected to the wireless communication channel as described above perform data communication through device initialization, search procedure, and the like, and disconnect and cut off the wireless communication channel after data transmission / reception is completed. It is common to do.

FIG. 23 shows a specific example of such inter-terminal communication. The second terminal on the receiving side is a printer, and the first terminal sends print data to the second terminal and prints the data. 7 shows an example in the case of a host device that instructs out.

[0007] In this case, after the device is initialized in each terminal, a print request is generated in the first terminal.
The standby second terminal is started through a search procedure and a connection procedure, and data is transmitted to execute printout.
Then, after the data transmission, the wireless communication channel is disconnected.

[0008]

However, in order to effectively perform communication in the above-described conventional example, in a terminal connected to a wireless communication channel, a power supply is activated in advance, and some operation is performed. It is assumed that it is in the state. Therefore, in this case, the power supply on the receiving side needs to be constantly activated, and there is a problem that wasteful power is consumed during the long standby state.

[0009] In addition, there is a problem in that some necessary procedures must be taken to transmit data through the wireless communication channel, which unnecessarily takes time.

An object of the present invention is to provide an inexpensive and simple wireless communication system capable of reducing power consumption during standby for performing communication between terminals, realizing data transmission by a simple procedure, and providing a simple and inexpensive wireless communication system.

In this embodiment, a case will be described in which predetermined parameters and image data are transmitted from the data terminal 71 to the facsimile to perform a facsimile transmission operation.

When a facsimile transmission operation start request is generated at the data terminal 71 by an operation of an operator or the like (S201), the data terminal 71 transmits an activation signal (facsimile transmission request control signal) to the facsimile 72 (S202).

This facsimile start signal has a control signal format as shown in FIG. 3, as in the first embodiment, and specific data indicating a "facsimile transmission request" is inserted in the control parameter portion.

When the facsimile receives the start signal (S

When the data transmission of the image file to be transmitted to the facsimile is completed (S205), all the operations of the data terminal 71 of this embodiment may be terminated, but the data terminal 71 manages the facsimile transmission ( Facsimile 7 if it is necessary to perform
It waits for the reception of the communication result notification transmitted from 2 to the data terminal 71 (S206).

The data terminal 71 simultaneously counts a certain time (for example, 10 minutes). If no communication result notification is received during that time (S206), the data terminal 71
It is determined that the wireless communication channel between the FAX 1 and the facsimile 72 is not connected for some reason, and the data terminal 71
Notifies the operator to that effect using display means or the like (S
207). Note that the counting time may be automatically set by the data terminal 71 according to the amount and contents of the document to be transmitted by facsimile.

When the data terminal 71 receives the communication result notification from the facsimile 72, it performs a predetermined operation according to the content of the notification (S209), and ends all the operations of the data terminal 71 of the present embodiment.

On the other hand, when the facsimile 72 receives the data necessary for the calling operation and the facsimile transmission operation from the data terminal 71 (S303), the facsimile 72 starts the calling operation according to the parameters received from the data terminal 71 (S304). ,

In the case where the state of the telephone line connected to the facsimile 72, a malfunction of the other party's facsimile, or the operator enters an incorrect telephone number and the call cannot be connected (S305), the facsimile 72 is Then, the line is disconnected without performing the facsimile transmission operation and the operation is terminated (S308), the result is transmitted to the data terminal 71 (S309), and the power of the hardware necessary for the facsimile transmission operation is turned off (S310). ), The entire operation of the facsimile 72 of the present embodiment ends.

In the first and second embodiments, the first
An example is shown in which image data and the like are transmitted from a data terminal that is a terminal to a printer or a facsimile that is a second terminal to perform a printing operation or facsimile transmission. However, the second terminal has a memory with an appropriate capacity. In this case, the data is transmitted in advance from the first terminal to the second terminal, temporarily stored in the memory of the second terminal, and the power other than the memory of the second terminal is turned off, and then the printing or When it is desired to execute facsimile transmission, the printer or facsimile may be activated again to print data stored in the memory or to perform facsimile transmission.

In this case, when data is to be transmitted from the first terminal to the second terminal in advance, for example, a “data reception request control signal” is transmitted from the first terminal to the second terminal, and

The second terminal, which is a facsimile, turns on the power of the facsimile transmission unit and starts a calling operation based on the calling parameters transmitted from the first terminal.

In this case, it is assumed that the parameters for facsimile transmission (paper size, resolution, etc.) are simultaneously transmitted when the first terminal transmits image data to the facsimile in advance.

Also, the above-mentioned calling parameters may be transmitted simultaneously when the first terminal previously transmits image data to the facsimile.

It is also possible to transmit the facsimile transmission parameters again simultaneously with the outgoing call parameters. If the transmission parameters are different from the previously transmitted transmission parameters, the image data is converted accordingly.
