[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is suitable for application to devices and systems that have a standby state (in a facsimile machine, a reception/transmission standby state), such as a facsimile machine. This paper relates to improvements in power supply control methods.

[Technical background of the invention]

Conventionally, in the case of a fufushishu device, when it is in the receiving standby state, it is busy,
Power is supplied to the entire system, and power is supplied to the entire system even during the timer operation when only the timer is operated and the system enters a reception standby state from a predetermined time. This is because the entire system receives power from one power source.

[Problems with background technology]

Therefore, in the conventional power control system of facsimile machines,
There is a problem that power is wasted, and there is also a drawback that it is not possible to provide power to only appropriate functions to perform appropriate processing.

[Purpose of the invention]

It is an object of the present invention to provide a power supply control method that allows only processing to be performed.

[Summary of the invention]

Therefore, in the present invention, a system is constituted by a first control means and a second control means which is supplied with a staining force by a power source different from the first control means, and the second control means is The above object is achieved by controlling the power supply of the first control means by the control means.

[Embodiments of the invention]

FIG. 1 is a block diagram of the main parts of a facsimile machine adopting the method of the present invention. In the figure, a 101 Fi main control section is shown, and this main control section 101 performs overall control of each section of the facsimile machine. An information path 102 is connected to the main control unit 101, and a clock unit 10 is connected to the information path 102.
3. Remote control unit 104. An operation panel 107 is connected. The main control section 101 exchanges data with each section via this information/9 bus 102.

In addition, the remote control unit 104 and the clock unit 1 are surrounded by broken lines.
03 means that the clock unit 103, which is operated by being supplied with power from a power supply separate from other parts, receives time data settings from the remote control unit 104 via the information path 102 and starts measuring time. When the set time has elapsed, a time interrupt signal 108 is output as a signal to the remote control section 104. Furthermore, the time data of the clock section 103 is stored in the main control section 1.
01 can also be read. The remote control unit 104 is
The main control unit 101 gives time data setting commands for the clock unit 103 and time data to be set. The remote control unit 104 also receives a time interrupt signal 108 from the clock unit 103.
When the power-on interrupt signal 105 is received as active from other parts, the main power control signal 106 that turns on the main power (the power of each part not surrounded by the broken line) is output as active, and the power control signal 105 is output as active. Analyze the cause based on the error signal and send the data about the cause of the occurrence to information.
2 to the main control unit 101. The operation panel 107 has various display lamps and various keys, and in this embodiment, the clock section 1030 has a middle key that can be manually operated to set the time data.

In the facsimile machine configured as described above, the main control unit 101 and the remote control unit 104 are both configured as a program-controlled combination device.
1 Fi The program shown in the flowchart shown in FIGS. 2 and 3 is executed, and the remote control unit 104 executes the program shown in the flowchart shown in FIG.

Main control unit 101 F! , in the second cause 201, input is taken in to detect whether or not there is a processing request. When there is a processing request, the main control unit 101 analyzes in 202 whether or not it is an online processing request. As a result of this analysis, if it is an online processing request, the main control unit 101
Processing will be done online.

Here, in the online processing, various processing related to communication with the other party's facsimile device is performed. As a result of the analysis in step 202, if it is detected that the processing is not online, the main control unit 10111204 performs offline processing. Here, in offline processing, copy mode processing,
In addition to importing various Norameters for automatic transmission and automatic reception,
The process for setting the timer shown in FIG. 3 is performed.

When it comes to offline processing, the main control unit 101Fi detects whether or not there is a timer set request at 301 in FIG. This timer set request is made by operating keys on the operation panel 107. When there is a timer set request, the main control unit 101 activates the remote control unit 104 via the information log 102 in step 303, and causes the remote control unit 104 to perform processing related to timer setting. If there is no timer set request, the main control unit 9 101 F1302 performs the corresponding offline processing other than the timer set, and returns to the routine shown in FIG. 2.

On the other hand, as shown in FIG. 4, the remote control unit 104Fi detects in step 401 whether or not there is a processing request, and if there is a processing request, it proceeds to step 402 and analyzes whether or not it is a timer set request. As a result of this analysis, if it is a reset request, the remote control unit 104 sets data in the clock unit 103 based on the time data sent via the information path 102 in step 403, and also sets the data in the clock unit 103 based on the time data sent via the information path 102. Turn off the main power. If the result of the analysis in 402 is that it is not a timer set request, the remote control unit 104 analyzes in 404 whether there is a power control interrupt that requires turning on the main power. For example, when the time set by the clock unit 103 has elapsed and the time interrupt signal 108 is output as active,
In addition, if the power-on interrupt control signal 105 is output as active from other parts, the process advances to 405, and the remote control unit 104 outputs the main power control signal 106 to the main control unit 101 to turn on the main power. At the same time, the interrupt generation cause data is sent to the main control unit 101 via the information path 102. As a result of the division in step 404, if it is not a power control interrupt that should turn on the main power supply, the remote control unit 104 performs other processing in step 406 (for example, reception of reservation of broadcast transmission time 2 reservation reception of output time of communication record information, etc.). )I do.

In the facsimile machine configured as described above, data input to start operation at a desired time is performed by
When this is performed from the e-channel 107, the remote control unit 104 sets the timer of the clock unit 103 and turns off the main power, reducing power consumption, and during this time, the remote control unit 104 can execute the necessary processing as described above. 0th order,
When a time-up occurs or there is a power control interrupt that turns on the main power (for example, an incoming call occurs during automatic reception), the main power is turned on by the remote control unit 104, and data on the cause of the interruption is generated. is given to the main control section 101. Thereby, the next process can be performed accurately based on the data on the cause of the interruption of the main control unit 101ti.

In this embodiment, the main power source is turned on when the timer is set, but the main power source may be turned off when the timer is set. Also, the range of the separate power supply indicated by the broken line does not have to be the range shown in Figure 1, therefore,
If this range is wider than this example, the remote control unit 1
04 expands the range of processing that can be executed when the main power is off.

Furthermore, the remote control unit 104 is provided with a function of providing interrupt occurrence cause data to the main control unit 101.
Although the load on the remote control unit 104 is reduced, the load on the remote control unit 104 is reduced.
It is possible to have more functions or to have fewer functions. In other words, each program can be designed to be flexible and simple.

〔Effect of the invention〕

As explained above, according to the present invention, there are two control means operated by separate power supplies, and one control means controls the power supply of the other control means, so it is possible to eliminate wasteful power consumption. Moreover, it is also possible to execute appropriate processing using only one control means.
