Abstract

PURPOSE:To make unnecessary a mode switching operation by switching a mode to a non-accumulation mode automatically when no destination transmission mode information of a designated destination is stored, or when the vacant area of a picture memory becomes few. CONSTITUTION:When a bit of destination information is inputted from an operation display device 9, a CPU1 judges whether the bit of destination transmission mode information of th destination is stored or not at a parameter memory 3. When a judgement is YES, it is decided whether the residual capacity of an image information memory 2 remains over a prescribed value. When the judgement is YES, after a transmission original set at a scanner 11 is accumulated on the memory 2, the bit of destination information is transferred to a communication controller 17, then calling the destination, and an accumulated image is transmitted to the destination. When an inputted bit of destination transmission mode information of the destination is not stored, and when the residual capacity of the memory 2 is few, a process is switched to a non-accumulation transmission process, and a transmission is performed without accumulating the image information on the memory 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile device having an image information storage function.

[Prior Art] In recent years, image storage devices having a large capacity image memory have been added, and facsimile machines have been put into practical use that can implement various useful functions using this image memory. for example,
When sending image information is accumulated in the image memory, there is a sequential reporting function that sequentially transmits the accumulated image information to multiple destinations, a time specified transmission function that allows you to specify the time to transmit to the destination, and a combination of sequential reporting and time specification. It is possible to realize a time-specific broadcast function, etc.

In addition, if received image information is stored in the image memory, if there is no special input such as a password from a specific recipient, the received image information will be
i! ! A confidential reception function that does not output 7 images, a relay relay function that sequentially transmits received image information to a plurality of other facsimile machines, etc. can be realized.

However, the capacity of an image memory provided in a facsimile machine is naturally limited, and it is not always possible to realize facsimile transmission using such a function.

Therefore, in the past, it was necessary for the operator to constantly monitor the remaining storage capacity of such image memory.
Based on the monitoring results, it is necessary to determine whether storage and transmission, in which image information is stored and transmitted, is possible or not, and to specify this to the device.

[Objective] The present invention has been made in order to eliminate the above-mentioned disadvantages of the conventional technology, and an object thereof is to provide a facsimile device that can reduce the burden on the operator and can perform appropriate storage and transmission. .

[Configuration] In order to achieve this objective, the present invention stores destination transmission mode information including encoding method data for each destination, and constantly monitors the capacity of the free space of the image memory that stores image information. If destination transmission mode information for a designated destination is not stored, or if the capacity of the free space in the image memory is less than a predetermined value, one-stroke information is not stored and transmitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a facsimile machine according to an embodiment of the present invention. Note that this facsimile device has not only an image information storage function and a transmission function, but also an image reduction/enlargement function and a linear density conversion function, and furthermore, can realize data processing functions similar to those of a personal computer.

In the figure, a CPU (C central processing unit) 1 manages and controls the operation of the entire facsimile machine.
A large-capacity main memory 2 consisting of a RAM (dynamic random access memory) is used as an image memory for storing information and as a work area for the CPU 1, and its empty area has a capacity of ff1 (i.e., remaining capacity: 51).
is constantly monitored by CP Old. A parameter memory 3 consisting of CMO3 (complementary MO3)-RAM stores destination information such as a telephone number and the encoding method of the destination.

Destination transmission mode data consisting of transmission speed, linear density, recording paper size, etc. is stored for each destination, and this parameter memory 3 is backed up by a battery 4.

In addition, ROM (read-only memory) 5 contains C.
Execution programs such as system programs executed by P old are stored.

The character generator 6 is used to convert character information into corresponding bit raster data when the plotter 10 (described later) records communication management information and other character information (received information during character code transmission, program list, etc.). 1 The clock circuit 7 generates the current time (including date information) in real time, and uses DMA
(Direct memory addressing) The controller 8 directly connects peripheral devices and the main memory 2 or parameter memory 3, or between peripheral devices via the system path line SB without going through the CPU This is for high-speed data transmission.

The operation display device 9 includes various operation devices, screen display devices such as a high-resolution liquid crystal display, and display devices such as a mode display device that displays the setting status of various modes. The plotter 10 records an image at a predetermined resolution, and the scanner 11 separates the image into pixels at a predetermined resolution and photoelectrically converts the images into both signals.

The encoding and compression devices 112 and 13 encode and compress the image signal, and one of a plurality of encoding methods is selected as the encoding method. Further, the code reproducing device 14 decodes the encoded image information formed by the encoded compression bags [12, 13 and the received image information into the original image signal.

The image processing device 15 reduces or enlarges the image at an arbitrary scale and converts the linear density, and the auxiliary storage device 1
6 stores a large amount of data using a storage medium such as a flexible magnetic disk. It is also possible to use an operating system that uses this auxiliary storage device 16, in which case this facsimile machine can be used as a data processing device equivalent to a personal computer.
Can be used.

The communication control unit 17 includes a control unit that executes facsimile transmission control procedures, a dem that modulates and demodulates data when transmitting data using a line network such as a public telephone line, and a network that connects the facsimile apparatus to the line set. It consists of a control device. Note that the control section of the communication control bag [17] can also be caused to execute transmission control procedures when transmitting other data such as character code transmission.

In addition, these CPU 1, main memory 2,) (parameter memory 3, ROM 5, character generator 6, clock circuit 7, DMA controller 8, operation display section 9, plotter 10, scanner ratio encoding compression device [112, 13, code reproduction Bag @141 The image processing device 15, auxiliary storage device 16, and communication control device 17 are each connected to the system A line SB, and data exchange between these elements is via this system A line SB. Furthermore, since each of these elements is well known, a detailed explanation thereof will be omitted.

With the above configuration, when transmitting image information, a transmission process 100 as shown in FIG. 2 is executed.

In the transmission process 100, first, when the operator inputs destination information from the operation display device 9 while setting the transmission document on the scanner 11, the result of the determination 101 becomes YES.

Thereby, the CPU determines whether the destination transmission mode information of the input destination is stored in the parameter memory 3 (determination 102).

If the result of this judgment 102 is YES, CFJJl
103), the result of this judgment 103 is YES.
If so, a storage and transmission process 104 is executed in which the transmission document set in the scanner 11 is stored and then transmitted.

In this storage and transmission processing 104, first, the encoding method of the destination transmission mode information is set to code ratio compression (wtzc or 13).
With this setting, the scanner 11 is operated and the image signal read is encoded by the encoding/compressing device 12 and stored in the main memory 2.

When this storage is completed, the destination information is transferred to the communication control device 17 to make the destination call, and when it is confirmed that the destination's transmission mode has not been changed by the exchange of information in the pre-transmission procedure, the main memory The image information stored in the device is transmitted to the destination.

At this time, if the transmission mode of the destination has been changed, the image information stored in the main memory 2 is restored to the original image signal by the code reproducing device 14, and the linear density is changed at that time. When the size of the image that can be received has been changed, the image processing device 15 changes the size of the image,
When the encoding method has been changed, the changed encoding method is set in the encoding/compressing device 12 (or 13), the image signal is encoded again, and the image signal is transmitted to the destination in that state.

When the storage and transmission processing 104 is completed, it is determined whether the transmission mode has been changed or not (determination 105), and this determination 1 is performed.
If the result of step 05 is YES, the destination transmission mode information of the destination is updated and stored in the parameter memory 3 (process 106).

If the destination transmission mode information of the input destination is not stored, the result of determination 102 is NO, and the CPU executes non-storage transmission processing 108.

In this non-storage transmission processing 108, first, the operator executes the mode setting operation necessary for transmission, and then transfers the input destination information to the communication control device 17 to make a call to the destination. , transmits image information according to the input mode.

When this is completed, the various transmission modes of the destination determined through interaction with the destination in the pre-transmission procedure are stored in the parameter memory 3 as the destination transmission mode of the destination (process 109).

Further, even if the destination transmission mode information of the input destination is stored, if the remaining capacity of the main memory 2 is less than the predetermined value, the result of determination 103 is No, and therefore,
The CPU performs processing 107) to display to the operator that storage and transmission is not possible.

The process moves to non-storage transmission process 108.

It should be noted that since the present invention relates to the transmission process of facsimile machine A, the explanation of the reception process and various other processes will be omitted.

In this way, the facsimile machine itself determines the possibility of storing and transmitting data, and there is no need to set the transmission mode for destinations that have been transmitted to at least once, which greatly reduces the burden on the operator. At the same time, it is possible to prevent the inconvenience of not being able to transmit image information due to incorrect setting of the transmission mode.

Note that the present invention can also be applied to facsimile machines that do not have the above-mentioned data processing function.

[Effects] As explained above, according to the present invention, destination transmission mode information including encoding method data is stored for each destination, and the capacity of the free space of the image memory for storing image information is constantly monitored. , if the destination transmission mode information for the specified destination is not stored, or if the free space in the image memory becomes less than a predetermined value, the image information is transmitted without being stored, so the storage transmission is not possible. The operator does not have to determine whether the
The burden on the operator can be reduced. In addition, an advantage is obtained in that appropriate storage and transmission is possible.
