Abstract

PURPOSE:To discriminate easily the used amount and the remaining amount of a memory by providing a display means representing the using or idle state of data in the memory. CONSTITUTION:The picture information read by a read section 3 is processed by a central control section 5, stored in a memory of a picture memory section 6 and the amount of the memory used for the storage is displayed on a display section 2 by the control section 5. The data in the memory is read sequentially, sent via a line 10, the data from the line 10 is written in the memory and read sequentially, recorded by the recording section 4, the rate of use of the memory is displayed always for the transmission and reception state. The display section 2 consists of an LED array or the like, a hatched part 12 shows the rate of occupied memory by data in the unit of %, and a space 11 shows the vacancy of the memory. Whether or not the next data read is availabel is discriminated by observing the rate of data shown in the hatched part 12.

Description

[Detailed description of the invention] (Field) The present invention relates to a data processing device having a memory.

(Background) For example, facsimiles are known in which data read by a facsimile is stored in a memory and then transmitted over a line, or the transmitted data is stored in a memory and then recorded.

(Problem) If an attempt is made to store a plurality of manuscripts with a large amount of information in such a memory, or if an attempt is made to store them between outputs from the memory, an overflow may occur.

To solve this problem, there are devices that display the memory usage status.

However, even by looking at the display, it may not be possible to immediately determine how many sheets or what kind of documents can be stored.

(Objective) The present invention eliminates the above-mentioned drawbacks and reduces the amount of memory used.
To improve a data processing device that allows the remaining amount to be easily determined.

(Summary) The disclosed device stores data such as images, and has a display means that indicates the usage state or free state of data in the memory, and when data is stored in the memory or output from the memory, the display is displayed. The device is characterized by displaying the usage status or free status of data by a means, and the memory is removable with memories of different storage capacities, and the display means changes the display unit in correspondence with the memories of different capacities. The data processing device has several characteristics.

(Embodiment) Fig. 1 is a control block diagram of a facsimile machine. 1 is an input section for operating the device, 2 is a display section for displaying the input state of the input section or the memory state, and 3 is a reading section for reading a document. section, 4 is a recording section for recording read information or received information, and 5 is an operation input 1 for displaying, reading, recording,
a central control unit that controls storage, etc.; 6 a memory that stores image information read from the reading unit 3; 7 a modulation/demodulation unit that modulates signals to transmit stored information and demodulates received information to store it; 8 is a network control unit that controls a telephone network to which the device is connected to transmit and receive information; 9 is a telephone; and 10 is a public telephone line.

In the above configuration, the image information read by the reading section 3 is compressed into MH or the like by the central control section 5, or stored in the memory of the image storage section 6 as it is. The control unit 5 calculates the amount of memory 6 used for storage and displays it on the display unit 2.

The data sent from the reading section in the memory is sequentially read out during transmission, modulated, and sent to a distant place via the line IO.

Further, data sent through the line 10 is demodulated, written into a memory, sequentially read out, decoded, and recorded by a recording section.

The memory filling rate is constantly changing and displayed during transmission and reception. When there is no free space in the memory 6, a warning that the reading unit 3 cannot read the transmitted original is displayed.

Figure 2 shows an example of how the filling rate is displayed when the installed capacity of memory (pack, cartridge type) is maximum.

It consists of an LED array, etc. The shaded area 12 indicates the percentage of the memory filled with data, and the white area 11 indicates the free space of the memory.The operator determines whether it is possible to read the next data by looking at the percentage of data in the shaded area. do.

Figure 3 shows the filling rate when the installed capacity of the memory (removable to the facsimile) is not the maximum, and a gap 15 is provided from one end of the graph corresponding to the difference in memory capacity from when the maximum memory capacity is installed. The filling rate is displayed in the hatched area 14 with the filling rate at the end of the gap being 0%. The blank area 13 indicates the free space in the memory.In this way, it is possible to easily visually judge how much information can be stored in the free space in the memory, regardless of the capacity of the pack memory.

Storing image data usually requires a large capacity memory even if the data is compressed. Moreover, reading or receiving and storing a plurality of original images requires a considerable amount of capacity and is expensive. Therefore, it is conceivable to make the memory capacity variable and selectable, taking into account the user's usage type 1 communication frequency and the like. Therefore, by displaying as shown in Figure 3, it is possible to read the memory filling rate in correspondence with the absolute amount of data regardless of the memory capacity, allowing the operator to determine whether the next document can be sent. There is no need to change the judgment criteria depending on the size of the memory, and it is also possible to read the installed capacity of the memory.

FIG. 4 is a flowchart of memory display control, which is executed by a program by the CPU of the control unit 5 and the ROM.

When a memory pack is attached, it is determined whether it is a large-capacity type A or a small-capacity type B (1).This is determined by reading the state of a switch operated by a cam attached to the pack. In the case of type A, the memory capacity is displayed on the display 16, which is composed of a 7-segment light emitter, as shown in Fig. 2, assuming three pages of originals with standard information content (2), and in the case of type B, it is displayed as 2 (2). 3) Then display the reference display points of 0% and 100% as shown in FIG. In type B, the 0% position is shifted and displayed (5).

Data storage and reading from the memory 6 is executed by sequentially specifying memory addresses by the control unit 5, and the control unit 5 has a counter for incrementing the address for this purpose. Therefore, the address counter should be monitored when storing and reading data 6), and it should be determined whether it has reached a predetermined count value n1 7). When nl is reached, the required number of LED indicators are selected and the LEDs are turned on. Turn on the light (8). In this case, the A type is the L from the lowest 0% image position as shown in Figure 2.
Select EDm, and in the case of B type select LED n from the middle 0% position and turn it on. Then, return to step 6, monitor the address counter again, judge whether it is n2, and repeat the above steps. In other words, when reading the original and storing the encoded data in the message, or storing the encoded received data as it is in the memory. 9 lights up when stored in
ED gradually increases from 0%, stops increasing in synchronization with the completion of reading one document, and continues displaying thereafter.

Next, when reading from the memory and sending it to the transmitter or outputting it to the printer, monitor the address counter in the flowchart in Figure 4 and turn on the LED corresponding to nl and n2-1.
is selected, but the light goes out one after another, contrary to when it is stored.

By monitoring and displaying the memory state of the code data memory in the document processing device, it is possible to predict the number of documents for a large capacity memory.

The storage status may be displayed as a percentage numerical value, a 9-circle graph, etc. as a display means.

(Effects) According to the present invention, it is possible to easily determine whether or not the next information such as a manuscript can be read. Furthermore, whether transmission is possible or not can be determined on the display using the same criteria regardless of the size of the memory capacity.
