Furthermore, since the priority busy signal is used, it is convenient for continuous copying operations using a copying machine.

[Examples] The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a block diagram showing an embodiment of the electrical equipment control method of the present invention.

In the figure, 1 is a power supply system 7 to which an electric device 6 is connected, 62 is a load such as a heater, and 61 is a heater control circuit for controlling the load 62. The ID circuit 67 is a circuit that sets and outputs two types of signals specific to the electrical equipment 6. For example, a signal of 200 Hz is output for use, and a signal of 300 Hz is output for priority. The in-use signal oscillation circuit 661 receives 200 signals from the 10 circuits 67.
This circuit modulates a high frequency signal of, for example, IKHz by one width or frequency using a specific signal of Hz, and outputs the modulated signal in use to the power supply system 1. Further, the priority signal oscillation circuit 662 receives the 3
This circuit frequency-modulates, for example, a high frequency signal of IK Hz using a specific signal of 00 Hz, and outputs the modulated own priority use signal to si and source system l. The receiving circuit 65 is a 50/60H existing in the power supply system l.
This circuit detects signals other than the z current, that is, the above-mentioned in-use signal and priority-in-use signal. The main circuit 63 includes the receiving circuit 6
5 is means for receiving the received signal and determining whether it is a signal other than its own. Further, the main circuit 63 is also a circuit that outputs instructions to cause the heating circuits 661 and 662 to output these specific signals. The control circuit 64 is the receiving circuit 6
5. Main circuit 63, heater control circuit 61, source circuit 661
．． This is a circuit that relays signals between 662 and 662.

FIG. 2A is a flowchart showing the operation of the embodiment L.

When the electrical equipment preferentially supplies power to the heater 62 (steps St, S2), the receiving circuit 65 checks whether another priority use signal exists in the source system M and the source system l (step 515). If it exists, it waits (step 517). On the other hand, it is also possible to first output the priority use signal with its own ID and then check the existence of other priority use signals.

Furthermore, it is checked whether there is a busy signal from another electrical device (step 519). If it exists, it remains on standby (step 520). If it does not exist, a busy signal is output (step 518). Then, power is supplied to the load 62 (step 521). In contrast, it is also possible to first output the use signal with its own ID and then check for the existence of other use signals.

If the load 62 is to be turned off during priority use (step 522), first the heater 62 is turned off (step S24.826) and the in-use signal is turned off (step 828).

On the other hand, if the load 62 is to be turned on (step 52
9), return to step 31B again and proceed with the step.

To end priority use (step 522), load 6
2 is turned off (step 523), the busy signal is turned off (step 525), and the priority use signal is turned off (step 527).

On the other hand, if priority is not used (step S2).

It becomes normal use mode. If the device is to be used normally, it is checked whether there is a priority use signal from another device (step S3). If there is, the priority use flag (FLAG-Y) is set to the number of that device (step S5). If it does not exist, set the flag to O (
Step S4).

Then, the presence or absence of the busy signal is checked (step S6).

If it is in use, wait until it runs out (step S9).
). If there is no signal, a busy signal is output (step S7).
). In contrast to this, the device may first output its own ID-attached busy signal and then check other people's busy signals.

Then, the own load 62 is turned on and used (step 510). However, if the other priority flags are not 0, the load 62 is turned off (step 513), and if the priority flag is 0, the load 62 is kept on (step 512). After turning off the load 62, it turns off its own in-use signal (step 514).

FIG. 2B is a diagram showing the operation of another embodiment of the present invention, in which a signal with an ID unique to oneself is first outputted, and then a signal unique to another person is checked.

The explanation will focus on the differences from the flow shown in FIG. 2A. Note that depending on the combination of notes in the explanation of FIG. 2A, some parts may overlap with the flow of FIG. 2B.

As shown in the figure, when priority use is to be made, a priority signal with ID is first output (step 16).
. Further, the in-use signal is also attached with an ID and outputted first (step 1B). Furthermore, both the priority use signal and the busy signal are attached with an ID to distinguish other people's signals from one's own.

On the other hand, in the case of normal use, in step 7, an in-use signal with ID is first output. Then, someone else's I
The presence of a busy signal with D is checked (step S8).

In addition, in this example, the unique signal is not modulated,
It may also be created by changing the frequency of the carrier signal itself.

In addition, if you output your own priority use signal or busy signal to the power supply system after checking the priority use signal or busy signal, the priority use signal or busy signal There is no need to create a signal specific to that electrical device.

That is, a common priority busy signal and a common busy signal can be used.

FIG. 3 is a flowchart showing an example of the operation when a copying machine is used as the electrical device of the present invention.

In the figure, when the copying machine attempts to use the fixing heater, the main circuit 63 checks the signal from the power supply system 1 as described above to determine whether electric power can be used (step Sl). ). Then, if it can be used, the heater is driven and the copy is executed (step S2).
. On the other hand, if the copying machine is not usable, the main circuit 63 uses an LED element or a liquid crystal element on the operation panel of the copying machine to display that copying is not possible (step S3).

In addition, if power is not available during one-shot copying,
Continue copying without turning on the heater and check again to see if power is available.

Note that when performing continuous copying, the mode is set to priority use mode, and power for continuous copying can be consumed preferentially. If priority use is not possible, single-shot copying is repeated, and when priority use becomes possible, priority use mode is entered and continuous copying is performed.

FIG. 4 is a flowchart showing an example of the operation when a laser facsimile is used as the electrical device of the present invention.

In the figure, when the laser facsimile tries to use the heater, the microcomputer etc. checks whether there is any received data before doing so (step Sl).
, when there is received data, the main circuit 63 determines whether or not power can be used as described above.
The signal is checked (step S2). If it can be used, the heater is driven and the received data is printed (step S4). If it is not possible to use it, and it is in the process of receiving printing, the page being printed continues to be printed with the heater turned off, and the remaining data is saved in an auxiliary storage device such as a hard disk or ram disk ( Step S3).

Note that if there is no received data, it is checked whether there is data in the auxiliary storage device (step S5), and if there is,
It is checked whether electric power can be used (step S6), and if it is possible, the data in the auxiliary storage device is printed (step S7).

Note that while transmitting, it continues to transmit and checks whether power is available.

Also, check whether power is available even during standby.

Note that printing can be ensured by setting the priority use mode while an image is being received and printed.

FIG. 5 is a flowchart showing an example of the operation when a laser printer is used as the electrical device of the present invention.

In the same figure, when a laser printer tries to use a heater, it first checks whether it can use electric power or not.
Check as described above (step Sl). If it is usable, the data sent from the host computer is printed (step S3). If power is not available and printing is in progress, only the page currently being printed is printed, and the remaining data is stored in a buffer (step S2). If the buffer is full, the host computer is made to interrupt data transmission (step S4).
．． S5). Once power is available, printing will resume and
Receive data from the host computer according to buffer availability.

If the printer is outside the printing tool and power cannot be used, printing is not performed and the data is stored in the buffer as described above.

FIG. 6 is a block diagram showing one embodiment of the adapter of the present invention.

In the figure, reference numeral 100 denotes an adapter, which includes a plug 23 connected to the outlet 3 of the power supply system 1, a main circuit 63, an ID circuit 67, an in-use signal oscillation circuit 661, . A control section 11 that performs the same functions as the priority signal oscillation circuit 662, the reception circuit 65, etc., and a current control section 12 that controls power in response to instructions from the control section 11.
The electric current control section 12 is connected to a power outlet 13 connected to the current control section 12. 99 is a device that consumes a large amount of power, such as an electric heater, and furthermore, the device can be controlled by the plug section. 991 is the plug part of the electric heater.

The plug portion 991 is connectable to the outlet 13 of the present invention.

Next, the operation of the adapter of this embodiment will be explained based on FIG. 7.

The control unit 11 of the adapter 100 checks whether there is a busy signal from another electrical device in the power supply system 1 (step Sl). If there is none, it outputs an in-use signal and supplies power to the electric heater 99 (steps S2 and S3).
. Then, after a predetermined time has elapsed (step S
4), the power supply is stopped (step S5), and the output of the own in-use signal is stopped (step S6). Then, the process returns to step Sl again to check the usage status of other electrical equipment. If no other electrical equipment is used, use the electric heater 99 again.
Begin powering as described above.

Also, when using electric power preferentially, it can be implemented as described above.

Note that it is also possible to first output its own in-use signal or priority-in-use signal, and then check other in-use signals or priority-in-use signals.

In this way, the adapter 100 according to the present invention can be used even when it is desired to use the same power source with an ordinary electrical device such as an electric heater that does not particularly check the in-use signal or the priority-in-use signal. Accordingly, in that power system l,
When the electric equipment 6 described in the above embodiment is connected, the electric heater 99 and those electric*appliances 6 can check each other's in-use signal or priority-in-use signal, so power consumption exceeds the rated power. There is no need to worry about being rejected.

The L current will flow and the power breaker will not trip. Furthermore, by using the adapter of the present invention, it is possible to prevent IE from tripping of the power breaker even if conventional electric equipment is connected to the same power source.

Furthermore, the use of the priority busy signal is particularly convenient when it is desired to send current to a load with priority.
