[0023]
Since the wireless communication means such as IEEE802.11b is a known technology, it will not be described in detail, but the outline is as follows.
[0024]
Communication is performed using a spread spectrum communication system (SS) using radio waves in a frequency band that does not require a radio license such as the ISM band (2.4 GHz band). Also adopted in IEEE 802.11-1997, the MAC layer and the physical layer are dedicated to wireless LANs, and transfer speeds of about 1 Mbps to 2 Mbps are mainstream.
[0025]
The spread spectrum communication system (SS) is a communication system originally developed for military use, and has excellent security and is resistant to noise. Also in this spread spectrum system, there are two systems, DSSS (Direct Sequence Spread Spectrum) and FHSS (Frequency Hopping Spread Spectrum), and these two systems are also used in IEEE802.11-1997.
[0026]
Further, since the facsimile apparatus FS1 uses the PLUG signal (VBUS signal) of the USB interface, the wireless unit section has a USB host interface, but another unit capable of transmitting print data. It may be.
[0027]
Further, the facsimile apparatus FS1 has two USB host controllers 10 and 18, but has three or more USB host controllers, and includes a plurality of units and one printing unit having a USB-P controller. The connection may be made, and even in this case, application is possible.
[0028]
Next, the operation of the above embodiment will be described.
[0029]
First, in the facsimile apparatus FS1, it is possible to print from a PC through wireless communication. On the other hand, when printing normal facsimile reception data and image data read by the reading unit 6, the same recording unit as that used for printing via the wireless communication is also used. That is, the facsimile apparatus FS1 is a facsimile apparatus having both a wireless printer mode and a conventional facsimile mode.
[0030]
Next, switching between the printer mode and the FAX mode in the above embodiment will be described.
[0031]
When printing from a PC by wireless communication, the wireless unit changes the PLUG signal, whereby the FAX control unit 1 recognizes the PLUG signal via the USB switching means 16, and the USB switching means 16 The first USB host control unit (first USB host control unit) 18 and the USB-P control unit 15 are connected. This state is the printer mode.
[0032]
Further, print data is sent from the PC to the wireless communication means (transceiver) 19. This is a data flow in which this data is received by the first USB host control unit 18 and sent to the USB-P control unit 15 via the USB interface via the USB switching means 16.
[0033]
Next, the operation when the user prints from the facsimile machine FS1 from the PC 20 via wireless communication will be described in detail.
[0034]
First, the user transmits print data from the PC 20 to the wireless communication unit (transceiver) 19. The PC 20 is provided with a wireless unit capable of communicating with the wireless communication means (transceiver) 19, and has dedicated software for communicating with the wireless communication means (transceiver) 19.
[0035]
Next, the wireless unit control section 17 determines whether or not the wireless communication means (transceiver) 19 is currently starting a reception operation. The wireless unit control unit 17 changes the level of the PLUG signal in the first USB host control unit 18 from L to H in order to switch to the USB host control unit 18 side.
[0036]
The USB switching means 16 having received this change notifies the FAX control unit 1 of this state. Further, the FAX control unit 1 controls the USB switching unit 16 to connect the first USB host control unit 18 and the USB-P control unit 15.
[0037]
The facsimile control unit 1 controls the entire operation of the facsimile machine FS1, and shifts the facsimile machine FS1 to the "printer mode" in response to the notification.
[0038]
The facsimile machine FS1 that has shifted to the "printer mode" cannot print the received image of the facsimile until returning to the "FAX mode".
[0039]
The first USB host control unit 18 and the USB-P control unit 15 connected by the FAX control unit 1 perform a USB interface procedure to establish a USB connection. Thereafter, when the USB-P control unit 15 receives the print data, the data is sent to the image recording unit 14 and printed. The control of the USB-P control unit 15 and the printing control are executed by the Printer control unit 11.
[0040]
By the time the printing is started, cancellation by the user, determination of the success or failure of the USB interface, determination of whether or not the data transfer is normal, and the like are performed by the FAX control unit 1, the Printer control unit 11, and the wireless unit control unit 17. Execute.
[0041]
In the case of the user cancel, the FAX control unit 1 detects the cancellation from the operation unit 4 and notifies the Printer control unit 11 of the cancellation, and the Printer control unit 11 transmits a USB connection to the USB-P control unit 15. Terminate. Further, the FAX control unit 1 causes the USB switching unit 16 to release the connection between the first USB host control unit 18 and the USB-P control unit 15.
[0042]
When the USB connection is terminated by the USB-P control unit 15 and the USB connection is released, the first USB host control unit 18, which is the other party, can also detect that. When the wireless unit control unit 17 detects this via the first USB host control unit 18, the wireless unit control unit 17 notifies the PC 20 of an error via the wireless communication unit (transceiver) 19. Further, it causes the first USB host control unit 18 to lower the PLUG signal from H to L.
[0043]
When the USB interface is not normally established or when a problem occurs in data transfer, the Printer control unit 11 detects the state via the USB-P control unit 15 in the same manner as described above. As in the case of the user cancellation, the Printer control unit 11 causes the USB-P control unit 15 to terminate the USB connection. Further, the FAX control unit 1 causes the USB switching unit 16 to release the connection between the first USB host control unit 18 and the USB-P control unit 15.
[0044]
When the print data has been transmitted normally and the printing has been completed normally, the Printer control unit 11 determines that the next print data has not arrived and that the set time t1 has elapsed from the end of the printing. , FAX controller 1.
[0045]
Upon receiving this notification, the FAX control unit 1 releases the connection between the first USB host control unit 18 and the USB-P control unit 15 established by the USB switching unit 16.
[0046]
When the connection is released, the wireless unit control unit 17 detects that the USB interface has been released via the first USB host control unit 18, and detects the level of the PLUG signal in the first USB host control unit 18. From H to L.
[0047]
The FAX controller 1 returns the apparatus from the “printer mode” to the “FAX mode”.
[0048]
During the “printer mode”, if there is a request for FAX printing from the second USB host control unit 10, the FAX control unit 1 monitors the PLUG signal, detects it, and sends it to the Printer control unit 11. The USB interface currently established with the first USB host control unit 18 is stopped, and a request is made to release the connection. Upon receiving the request, the Printer control unit 11 releases the USB interface, and when the connection is released, the first USB host control unit 18 notifies the PC 20 of the end of error suspension via the transceiver. At this time, printing from the PC 20 is stopped.
[0049]
Then, the FAX control unit 1 connects the second USB host control unit 10 and the USB-P control unit 15 by the USB switching unit 16, and the USB interface of the second USB host control unit 10 is established. Then, the FAX reception image data is sent to the USB-P control unit 15, and the printing operation is performed in the Printer unit.
[0050]
The above description is an operation in a case where the FAX reception image data is prioritized, that is, in a case where the FAX reception image is to be printed immediately. However, if the user desires not to give priority to the FAX reception image data, the printing from the PC 20 can be continued without stopping as described above, and the FAX reception image printing can be postponed. In this case, the received fax image may be stored in the memory, and after the “printer mode” ends, the mode may be shifted to the “fax mode” and printed immediately.
[0051]
Next, a description will be given of an operation up to the printing of a FAX reception image when reception is performed by facsimile communication.
[0052]
After receiving a call through a public line, the facsimile control unit 1 performs a communication procedure with the facsimile of the other party via the modem 7, compresses the received image by MH, and stores the image in a memory. Thereafter, the received image in the memory is sent to the second USB host control unit 10 for development and recording. Here, the FAX control unit 1 urges the Printer control unit 11 to prepare to operate the image recording unit 14 to print the received image.
[0053]
When the second USB host controller 10 receives the print data of the received image, the FAX controller 1 instructs the second USB host controller 10 to change the level of the PLUG signal from L to H. . On the other hand, the FAX control unit 1 connects the second USB host control unit 10 and the USB-P control unit 15 by the USB switching unit 16. Here, the facsimile control unit 1 causes the facsimile machine FS1 to shift to the “FAX mode”.
[0054]
The facsimile machine FS1 that has shifted to the "FAX mode" cannot respond to the print request from the wireless unit until the recording of the FAX reception image is completed.
[0055]
The connected second USB host control unit 10 and USB-P control unit 15 establish a USB connection. Thereafter, when the USB-P control unit 15 receives the print data, the data is sent to the image recording unit 14 and printed. The control of the USB-P control unit 15 and the printing control are executed by the Printer control unit 11.
[0056]
By the time the printing is started, the facsimile control unit 1 and the printer control unit 11 execute cancellation by the user, determination of the success or failure of the USB interface, determination of whether data transfer is normal, and the like. If there is a problem, the second USB host controller 10 promptly detects the abnormality and notifies the FAX controller 1 of the error.
[0057]
When the print data has been transmitted normally and the printing has been completed normally, the FAX control unit 1 detects that the next received print data has not arrived, and the FAX control unit 1 transmits the print data to the second USB host control unit. 10 to change the PLUG signal from H to L.
[0058]
During the “FAX mode”, when a change from L to H of the PLUG signal is input from the first USB host control unit 18 to the USB switching unit 16, the first USB host control unit 18 The operation is started in order to establish, but there is no response from the USB-P control unit 15. Therefore, since the first USB host control unit 18 cannot establish the USB interface, the first USB host control unit 18 returns the PLUG signal from H to L when a predetermined period of time has elapsed in which the USB interface cannot be established.
[0059]
Since the FAX control unit 1 monitors this PLUG signal, the FAX control unit 1 detects that there is a “connection request” from the first USB host control unit 18. Therefore, if a system configuration in which the print data is stored in the wireless unit is adopted, the print data from the PC 20 is temporarily stored in the wireless unit, and after the FAX reception recording is completed in the “FAX mode”, the first USB The host control unit 18 and the USB-P control unit 15 can be connected to record print data from the PC 20. In the above embodiment, for simplicity, the system configuration is such that print data is not stored in the wireless unit.
[0060]
In the above-described embodiment, the FAX control unit 1 and the Printer control unit 11 are described as two control units. However, these two control units may be configured as one control unit. In this case, the operations of the Printer control unit 11 and the FAX control unit 1 can be executed by one control unit.
[0061]
Next, among the above operations, an operation when printing via a wireless unit will be described.
[0062]
FIG. 2 is a flowchart showing an operation for printing via a wireless unit in the above embodiment.
[0063]
In S201, the facsimile apparatus is in the standby mode in the “FAX mode”, and the USB-P control unit 15 determines which one of the first USB host control unit 18 and the second USB host control unit 10 is the USB connection unit. Also not connected.
[0064]
In S202, in order for the user to use the facsimile machine as a printer, the print data is wirelessly transmitted from the PC 20, and when the wireless communication unit starts receiving, the wireless unit control unit 17 detects this and proceeds to S203. . In S203, the first USB host control unit 18 changes the PLUG signal to “H”, and proceeds to S204.
[0065]
In S204, the FAX control unit 1 detects the PLUG signal from the first USB host control unit 18, confirms the current state of the USB switching unit 16 and the state of the second USB host control unit 10, The second USB host control unit 10 and the USB-P control unit 15 determine whether or not a USB connection is currently in progress for FAX printing.
[0066]
If the connection is being made, that is, if the fax printing is being performed, the process proceeds to S205, and if not, the process proceeds to S208.
[0067]
In S205, if the FAX printing is being performed, the USB interface cannot be established by the first USB host control unit 18, so the wireless unit control unit 17 notifies the wireless communication unit of the BUSY state as "Printer BUSY", and S206 Proceed to.
[0068]
In S206, the BUSY state is notified to the PC 20 to which the wireless communication unit is wirelessly connected. In S208, the facsimile controller 1 shifts the facsimile machine to the “printer mode”, and proceeds to S209.
[0069]
In S209, before confirming the communication of the USB interface, the facsimile control unit 1 monitors that there is no input by the user such as the KEY operation of the print cancellation by the user, and the process proceeds to S210.
[0070]
In S210, the negotiation of the USB interface starts between the connected first USB host control unit 18 and USB-P control unit 15, and the printer control unit 11 monitors this. If the negotiation is normally performed, the process proceeds to S211. If the negotiation is an error, the process proceeds to S205.
[0071]
In S211, the Printer control unit 11 detects via the USB-P control unit 15 whether transmission and reception of data between the USB interfaces has been started. If the data transmission / reception is started normally, the process proceeds to S212, and if a data error such as no data is generated, the process proceeds to S205.
[0072]
In S212, if the printing is normally completed, the process proceeds to S214. If the recording unit notifies the Printer control unit 11 of an abnormality, the process proceeds to S213.
[0073]
In S213, the facsimile control unit 1 notifies the user of a recording unit error (recording paper jam, no recording paper, etc.) through a display unit, voice guidance, or the like, and returns to S201 (standby state in “FAX mode”). The printer control unit detects that the error of the recording unit is released, and the error notification is continued until the fax control unit 1 is notified.
[0074]
In S214, the Printer control unit 11 checks whether there is the next print data. When the next print data is input to the wireless communication unit, the flow returns to step S209 to print the next data in order to continue printing using the USB interface. If the Printer control unit 11 detects that there is no next print data, the process proceeds to S215.
[0075]
In S215, the FAX control unit 1 checks the elapsed time from the previous printing. If the elapsed time is longer than the specified time (settable by the user) t1, the process proceeds to S216. If the elapsed time is equal to or shorter than t1, the process returns to S209.
[0076]
In S216, the FAX control unit 1 causes the USB switching unit 16 to release the USB connection. When the USB interface is released, the first USB host control unit 18, which has been disconnected, changes the PLUG signal from H to L, and proceeds to S217. In S217, the FAX control unit 1 returns from the printer mode to the “FAX mode” standby in S201.
[0077]
That is, in the above-described embodiment, when the printing unit of the facsimile apparatus FS1 prints the facsimile reception image and also prints the print data from the PC 20 via wireless communication, the switching between the two is performed by the USB interface. , And can be smoothly executed. For wireless communication, existing technologies such as IEEE 802.11 and Bluetooth are used.
[0078]
The PLUG signal is one of the signals defined by the USB standard (such as USB Serial Bus Specification Revision 1.1). In addition to the differential data signal line called D + / D-, the PLUG signal is connected to the USB via the PLUG signal. Signal (also called a V-BUS signal).
[0079]
The PLUG signal is a signal for transmitting a USB connection to the peripheral side by supplying a specified voltage (H level) from the host (in this case, the PC 20).
[0080]
The PLUG signal is a signal that outputs an H level (+5 V) when the USB host control unit issues a “connection request” to the USB-P control unit (USB peripheral control unit) 15.
[0081]
In the above embodiment, two USB host controllers are provided, that is, a first USB host controller 18 on the wireless unit side and a second USB host controller 10 on the FAX side.
[0082]
The FAX controller 1, which controls the entire facsimile apparatus FS1, monitors two PLUG signals from the first USB host controller 18 and the second USB host controller 10, and monitors the monitored PLUG signal. The second USB host control unit 10 operates the USB switching unit 16 in accordance with the state of (1), and when the print data from the PC 20 is received by the wireless unit (wireless unit) or received by facsimile, Switches between facsimile printing and wireless unit printing.
[0083]
At this time, when printing data from the wireless unit, the first USB host control unit 18 and the USB-P control unit 15 are connected. On the other hand, when performing facsimile printing, the second USB host control unit 10 and the USB-P control unit 15 are connected.
[0084]
In the FAX control unit 1, the USB switching unit 16 always detects that either the first USB host control unit 18 or the second USB host control unit 10 is connected to the USB-P control unit 15. Then, the facsimile machine FS1 is shifted to a mode corresponding to the detection result.
[0085]
That is, if the destination connected to the USB-P control unit 15 is the first USB host control unit 18, the wireless communication unit 19 is selected, and thus the printer mode is “printer mode”. The second USB host control unit 10 is in the “FAX mode”.
[0086]
As a result, in the above-described embodiment, when a user who uses a facsimile as a printer performs printing from the PC 20 via wireless communication, it is possible to eliminate the operation of manually shifting the facsimile apparatus to the printer mode. Convenience can be improved.
