Abstract

PURPOSE:To prolong the working time of a facsimile equipment at the time of a power failure by reducing power consumption. CONSTITUTION:An original to be transmitted by a facsimile is read at an original reading part 2 and the received original is outputted by a picture output part 3. Received pictures are stored in a memory part 4 and the transmission and reception of the facsimile are performed at a communication control part 5. A power source detection part 6 checks the power supply of an AC power source part 8 and a DC power source part 7. In the case of the power failure, the power supply from the AC power source part 8 disappears and is changed to the supply from the DC power source part 7. The power source detection part 6 monitors the AC power source part 8 and when the power failure is detected, reports that effect to a system control part 1. When the report arrives, the system control part 1 reports it to the picture output part 3 and stops a cutter. Thus, the received original remains uncutted and the power consumption due to cutting by the cutter can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly, to a facsimile machine which saves power and has a longer operating time.

[0002]

2. Description of the Related Art As a known document describing the prior art of the present invention, there is, for example, Japanese Patent Application Laid-Open No. 2-82756. In this publication, when the recording function is abnormal, and if the received message is stored in the memory for a predetermined time, it is transferred to a predetermined destination. Further, the conventional facsimile apparatus having the battery backup function can operate even during a power failure, but it requires a large amount of power before outputting a document when it is received. Of these, the power to drive the cutter motor is no exception, and it is conceivable to reduce battery consumption by stopping the cutter and receiving the roll paper, which is the received document, without cutting it.
Further, when the facsimile machine wants to separate a document received at the time of a power failure, it is troublesome to separate it with a knife or the like, and it is conceivable that the document can be easily separated by hand by providing a blade in the received document discharge part.

Further, when the facsimile apparatus operating with the battery backup repeats communication, when the remaining battery power becomes low, the battery may be so low that the received document cannot be output even if communication is possible. In such a case, it is useful to be able to transfer the document transmitted until the next battery charging to another facsimile in which the document can be collected. Further, the battery consumption can be reduced by stopping the cutter during the operation during the power failure and receiving the roll paper as the received document without cutting it. However, if the power outage lasts for a long time, the messages received during that time will be discharged while being connected, and the subsequent processing will be very troublesome.

[0004]

[Purpose] The present invention has been made in view of the above circumstances, and it is possible to extend the operating time of a facsimile device at the time of a power failure by stopping the cutter at the time of reception to reduce the power consumption, and the remaining battery power. When there are few
When receiving a power failure, you can forward the received document to the other party specified in advance, and automatically cut the received document on the roll paper, but at the time of power failure, stop the cutter and cut it with the blade of the received document discharge section. In order to reduce the power consumption of the facsimile machine, and further to reduce the power consumption by cutting the received document in one communication unit at the time of power failure, the facsimile apparatus is provided.

[0005]

In order to achieve the above object, the present invention provides (1)
In a facsimile apparatus having a battery backup function and a cutter for cutting roll paper, a power supply detection unit that monitors the AC power supply unit and determines that there is a power failure,
A signal from the power source detection unit notifies the image output unit that there is a power failure, and a system control unit that stops the cutter of the received document discharge unit prevents the received document from being cut by the cutter. (2) A blade different from the cutter is provided in the received document discharge section,
When the power is cut off, the cutter is stopped and the received document is cut by the blade, or (3) in a facsimile apparatus having a battery backup function and a memory function, the DC power supply unit is monitored to receive the received document. A power supply detection unit that determines that sufficient power for output is not obtained, a system control unit that gives an instruction to store a received document in the memory unit by a signal from the power supply detection unit, and an instruction from the system control unit. A facsimile device having a communication control unit for transferring the read received original, or (4) a battery backup function and a cutter for cutting roll paper, the protocol is monitored and the protocol is finalized. A communication control unit that determines that the transmission of page image information has been completed, and a signal from the communication control unit With informing that the transmission further has ended to the image output unit, composed of a system control unit for driving the cutter, the power failure is obtained by said cutting the received document to one each communication rather than each page.
Hereinafter, description will be given based on examples of the present invention.

FIG. 1 is a block diagram for explaining an embodiment of a facsimile apparatus according to the present invention, in which 1 is a system control unit, 2 is a document reading unit, 3 is an image output unit, and 4 is a memory unit. 5, a communication controller, 6 a power detector, and 7 a DC
The power source unit 8 is an AC power source unit. The system controller 1 controls the functions of the entire facsimile apparatus. The original sent by facsimile is read by the original reading unit 2, and the received original is output by the image output unit 3. The memory unit 4 stores the received image, and the communication control unit 5 transmits and receives a facsimile. The power supply detection unit 6 checks the power supply of the AC power supply unit 8 and the DC power supply unit 7. The DC power supply unit 7 supplies DC power, and the AC power supply unit 8 supplies AC power. When a power failure occurs, the power supply from the AC power supply unit 8 is stopped, and the supply from the DC power supply unit 7 is replaced. When the power supply detection unit 6 monitors the AC power supply unit 8 and determines that there is a power outage,
Notify the system control unit 1. When the system control unit 1 receives the notification, it notifies the image output unit 3 to stop the cutter. As a result, the received document remains uncut.

FIG. 2 shows the embodiment shown in FIG. 1 (claim 1).

In the case of the last page, it is determined whether AC power is being supplied (step 8), and if AC power is not being supplied, the document is manually cut by a blade different from the cutter (step 9).

Next, another embodiment (claim 3) of the present invention will be described. Now, it is assumed that the AC power supply unit 8 does not supply power and the DC power supply unit 7 supplies power. When the communication is repeated, the battery is consumed, and the power supply detection unit 6 monitors the DC power supply unit 7 and if it determines that the power is not sufficient to output the received document, the system control unit 1 is notified. Sufficient power is the power required to output one page of the received document. When the system control unit 1 receives the notification, the received document is temporarily stored in the memory unit 4. Then, the received received document is taken out from the memory unit 4 according to an instruction from the system control unit 1 and transferred to a destination designated in advance through the communication control unit 5.

Next, another embodiment (claim 4) of the present invention will be described. The operation until the cutter is stopped by switching to the DC power supply at the time of power failure is the same as in claim 1. Then, the communication control unit 5 monitors the protocol, and EOP (End indicating that the transmission of the image information of the last page is completed
Of Procedures: When a procedure end signal) is detected, it is transmitted to the system control unit 1. The system control unit 1 notifies the image output unit 3 of the notification from the communication control unit 5, and cuts the roll paper as soon as the image output is completed.

FIG. 6 is a flow chart for explaining the operation of claim 4. First, the transmitted image information is received (step 1) and the image is output (step 2). Next, when a power failure occurs, it is judged whether AC power is being supplied (step 3). If AC power is not being supplied,
This is notified to the system control unit (step 4) and the cutter is stopped (step 5). In step 3, if the AC power is supplied, the document is cut for each page (step
6). Next, it is judged whether the transmission of the image information is the final page (step 7). If it is not the final page, the process returns to the step 2. If it is the last page, it is judged whether AC power is supplied (step 8), and if AC power is not supplied, the document is cut (step 9).

[0014]

As is apparent from the above description, the present invention has the following effects. (1) Effects on Claims 1 and 2: A facsimile device having a battery backup function can operate even during a power outage, but when received, it requires a large amount of power before outputting a document. The electric power for cutting the roll paper with the cutter is no exception and requires a large amount of electric power. Therefore, by stopping the cutter, it is possible to save power without affecting the received image, and it is possible to extend the operating time of the facsimile device. (2) Effect on Claim 3: A facsimile machine operating on a battery consumes the battery while repeating communication, and finally cannot receive a received image. Before that, the battery is checked, and if there is not enough electric power, it can be transferred to a facsimile device specified in advance so that the original sent by the next charging can be obtained. (3) Effect on claim 4: As in claim 1, the facsimile machine operating on the battery can save power by stopping the cutter for cutting the roll paper and prolong the operating time of the facsimile machine. You can However, if the power outage lasts for a long time, the telegram received during that time will be discharged while being connected, and the subsequent processing will be very troublesome. Therefore, by cutting the received document for each communication unit, the time and effort required for the document processing can be reduced, the power consumption can be saved, and the operating time of the facsimile apparatus can be extended.
