Abstract

PURPOSE:To hold part of storage reception data at power failure and to reduce the capacity of backup power supply by providing the 1st storage means storing part of received data and the 2nd storage means storing the remaining part and backing up the 1st storage means at power failure. CONSTITUTION:The 1st picture memory 16 stores part of the received data and the 2nd picture memory 17 stores the remaining part of the received data. In the event of power failure, a battery 18 supplies power to the memory 16 to hold the storage content. A recording control section 12 sends the holding data in the memory 16 to a recording section 15 at recovery of power supply and prints it out on a recording paper sheet. Then the capacity of the picture memory 17 is large and the picture signals by one communication are stored sufficiently with the capacity being the sum of the capacity of the picture memories 16, 17. Thus, even if power failure takes place, the transmission opposite destination is specified, the lost information is obtained quickly and a small capacity is enough for the battery 18 and the cost and space are reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a facsimile machine, and more particularly to power backup for a memory that stores received data.

(Prior Art) Conventionally, a facsimile machine cannot receive image information when there is no recording paper. Therefore, some facsimile machines have a function of temporarily storing received image information in a memory, and then reading the image information from the memory and printing it on recording paper by an operator's operation. By using such a function, image information can be received even if the facsimile machine runs out of recording paper at the time of reception, and then replenishes the recording paper and prints the image information on the recording paper. It is possible to output it. However, even with facsimile machines that have the above functions, if a power outage occurs after the received image information is temporarily stored in the memory and before the image information is printed out on recording paper, the image information stored in the memory will be lost. There is an inconvenience that information is lost and the situation ends up being the same as if image information could not be received. Therefore,
It may be possible to back up the memory with a battery or the like to retain the image information during a power outage, but since the capacity of the memory is large, the backup power source would be very large and the cost would be high, making this difficult to implement. Met.

(Problems to be Solved by the Invention) In the facsimile machine that temporarily stores received image information in a memory as described above and then prints out the image information on recording paper,
If a power outage occurs while image information is stored in memory but not printed out on recording paper,
There is an inconvenience that the image information is lost from the memory, and not only the contents of the image information but also the recipient of the image information cannot be known.

Therefore, if the memory is backed up with power to prevent loss of image information in the event of a power outage, the large capacity of the memory requires a large backup power source such as a battery, resulting in a significant increase in the cost of the device. . SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a facsimile machine which retains a part of stored and received data even if a power outage occurs, so that appropriate measures can be taken later. It is said that

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a facsimile machine that temporarily stores received data and then prints the stored data on recording paper using a recording means. a first storage means for storing a part of the received data; a second storage means for storing the remaining part of the received data; a power supply means for backing up the first storage means in the event of a power outage; and recording control means for sending the data held in the first storage means to the recording means and printing it on recording paper.

(Operation) In the facsimile apparatus of the present invention, the first storage means stores a part of the received data, and the second storage means stores the remaining part of the received data. During a power outage, the power supply means supplies power to the first storage means and retains the stored contents of this storage means. The recording control means sends the data held in the first storage means to the recording means to print it on recording paper when the power is restored. As a result, even if a power outage occurs, part of the stored data can be retained and retrieved.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus of the present invention. Reference numeral 1 denotes a facsimile device having a memory function for receiving image signals, 2 a telephone line connected to the facsimile device 1, and 11 a transmitting/receiving section for transmitting and receiving data, which includes a modem, a network control section, a changeover switch, etc. ing.

12 is a control unit that controls the operation of the entire device; 13 is an input unit through which the operator inputs dial information, printout commands, etc.; 14 is a notification unit that notifies the operator of the operating status of the device; and 15 is a unit that records data. 16.17 is an image memory for storing received image information; 1; a recording unit for printing on paper 19;
A battery 8 is a backup power source for the image memory 16.

Next, the operation of this embodiment will be explained. At the time of reception, the image signal transmitted via the telephone line 2 is received by the transmitting/receiving section 11, demodulated here, and then sent to the control section 12. The control section 12 decodes and expands the demodulated image signal, and normally sends it to the recording section 15. The recording section 15 prints the sent image signal on a recording paper 19. This recording paper 19 is outputted to the outside by a conveyance mechanism in synchronization with the printing operation. Here, when the recording paper 19 runs out, when the control section 12 detects this, it does not send the decoded and expanded image signal to the recording section 15, but sends it to the image memory 16. is stored in the image memory 16 and 17. At this time, the control unit 1
2 sequentially stores the received image signal from the leading edge of the image memory 1.
6, and when this image memory 16 becomes full, the subsequent image signals are written to the image memory 17.

However, the capacity of the image memory 16 is relatively small enough to store the image signal near the leading edge of the received image signal, and moreover, it is designed to be backed up by the battery 18 in the event of a power outage. . On the other hand, the capacity of the image memory 17 is large, and the combined capacity of image memo 1, 16, and 17 is sufficient to store image signals for one communication. When the control section 12 detects that the recording paper 19 is out of paper, the notifying section 14 notifies the operator of this.

When the operator learns of this paper shortage, he sets a new recording paper 19 and then gives a print command from the input section 13 to the control section 12. When the control section 12 receives this command, it reads out the image signals in the image memories 16 and 17 and sends them to the recording section 15, thereby printing and outputting the image signals.

However, at this time, if a power outage occurs before the operator sets a new recording paper 19 and issues a print command, the battery 18 backs up the power to the image memory 16 and retains the stored contents. When the power is restored, the operator sets a new recording paper 19 and then issues a print command from the input section 13 to the control section 12. As a result, the control unit 12
reads the image signal held in the image memory 16 and sends it to the recording section 15, thereby printing out the leading edge of the received image as shown in FIG. 2, for example. Normally, in facsimile communication, sender information such as the sender's name and the date and time of sending is automatically added to the top of the sent document, so as shown in Figure 2, the top of the received document includes the year of sending. Information such as the month, date, hour, minute, name of the company, and number of pages is printed on it.

According to this embodiment, even if a power outage occurs while the received signal is stored in the image memory 16 or 17 and the operator sets a new recording paper 19 and issues a print command, the image memory 16. The data at the leading end of the received signal stored in the system is not lost and can be printed and output on recording paper after the power outage is restored, so even if the power outage occurs,
Since the recipient of the transmission can be identified, the lost information can be quickly retrieved by taking appropriate measures such as requesting transmission again. Further, since the battery 16 only needs to have a small capacity to back up only the image memory 16, which has a small capacity, the present invention can be easily implemented without increasing the cost and space of the apparatus.

[Effects of the Invention] As described in 3 above, according to the facsimile apparatus of the present invention, even if a power outage occurs, a part of the received received image stored is retained, and when the power is restored, this retained received image is transferred to recording paper. It can be printed out.
