[0024]
In FIG. 3, (a) is a basic screen, and this screen is displayed in a standby state. On this screen, the original image is read by setting the original, setting the reading mode (resolution, density, image quality), inputting the destination by using the numeric keypad or one-touch key of the operation unit 1-5, or the speed dial. 1 and stores the read image data in the image storage unit 1-2.
[0025]
When the facsimile status key 3-1 is pressed on the screen (a), the screen is switched to the screen (b). (B) is a screen showing a list (communication reservation status) of image data (here, 17 cases) stored in the image storage unit 1-2. 5 items can be displayed at a time, and other items can be displayed sequentially by scrolling with the up and down keys. In this list, from the left, the reception time, destination number (user abbreviation if a user abbreviation is registered, display in case of broadcast and the number of transmissions), reception number, and communication result. Touch the desired item in the list to switch the display to reverse display. When the stop key 3-2 is pressed here, the image data is deleted from the image storage unit 1-2, and the matter is deleted from the list. Further, when the detailed information key 3-3 is pressed while one item is highlighted, detailed information about the selected item is displayed as shown in (c). The list display in (b) is the case where a transmission document is selected. If there is no operation for a predetermined time on this screen, the screen returns to (a).
[0026]
(C) is a display screen showing detailed information about one item selected from the list of (b). In this case, it is assumed that the receipt number 1244 is selected. Here, transmission is started immediately by pressing the retransmission key 3-5. When the change key 3-6 is pressed, the screen is changed to a screen as shown in (d).
[0027]

If the address field is pressed here, this field is displayed in reverse video, and if the correction key 3-8 is further pressed, the screen is changed to a screen as shown in (f). The add key is used to add a destination, and the delete key is used to delete a destination (when broadcasting). When an abbreviation (added to the upper end portion of the image) is selected, the correction key 3-8 is pressed to newly add or correct the abbreviation.
[0029]
In (f), the destination telephone number is corrected using a numeric keypad.
[0030]
When the display as described above (c) to (f) is in the destination change processing mode, it is stored in the image storage unit 1-2 (the display screen of the operation unit 1-5). The transmission of image data waiting for transmission (displayed in the above) is not started.
[0031]
Further, when the OK key 3-9 is pressed on the screen (f), the screen is switched to the screen (a). Note that pressing the return key on each screen switches to the previous screen.
[0032]
Next, when transmitting image data, an operation from reading a document image by the reading unit 1-1 to accumulating the read image data in the image storage unit 1-2 will be described.
[0033]
FIG. 4 is a flowchart showing the flow of this operation.
[0034]
First, the operator sets a document to be transmitted to the reading unit 1-1, and designates a reading mode (resolution, density, etc.) from the operation unit 1-5. Also, the transmission start time is designated as necessary. Then, the destination telephone number is designated.
[0035]
Thus, the CPU 1-6-1 secures a management block on the RAM 1-6-3, sets management information and destination information in the management block, and stores them (S4-1).
[0036]
Next, the CPU 1-6-1 activates the reading unit 1-1 and the encoding / decoding unit 1-3. The original image is read in accordance with the reading mode designated here, and the image data obtained by the reading is input to the encoding / decoding unit 1-3 via the system bus 1-9. The encoded image data is stored in the image storage unit 1-2 (S4-2).
[0037]
When all the originals have been read and accumulated (S4-3), document information (reading mode, original size, address on the image storage unit 1-2, etc.) relating to the accumulated image data is set in the management block and stored. (S4-4).
[0038]
When the management block in the RAM 1-6-3 is set, an address indicating the storage position of this management block is stored in the area of the communication reservation queue provided in the RAM 1-6-3. Here, it is determined whether or not the communication reservation queue is empty (S4-5). If it is empty, it is linked to the head of the communication reservation queue as shown in FIG. 5A (S4-7). Link to the end of the communication reservation queue as shown in (b) (S4-6).
[0039]
The communication thus reserved is transmitted later, but the operation shown in the flowchart of FIG. 4 is executed independently regardless of the communication operation. Therefore, if a transmission operation is further performed as described above, management blocks are successively linked to the communication reservation queue.
[0040]
Here, FIG. 5A shows a case where the communication reservation queue is empty, and an address indicating the storage position of the management table set as described above is set at a position indicating the head of the communication reservation queue. On the other hand, FIG. 5B shows a case where the addresses of the management block (1) and the management block (2) are already set in the communication reservation queue, and the address of the management block set as described above is the next position. Set to.
[0041]
Next, the flow of information change processing relating to image data accumulated as described above will be described with reference to the flowcharts shown in FIGS.
[0042]
First, in S6-1, it is determined whether or not the fax status key has been pressed in the display as shown in FIG. 3A which is the basic screen in the standby state. The transmission prohibition flag for the image data waiting for transmission stored in 1-2 is turned on so that transmission is not started. Then, the presence or absence of the management block is identified by determining whether or not the address of the management block is set in the communication reservation queue (S6-3). If there is a management block, the information stored in the management block is sequentially read out and displayed as a list as shown in FIG. 3B (S6-4). If there is no management block, the list is not displayed.
[0043]
Next, in S6-5, it is determined whether a predetermined time (for example, 1 minute) has elapsed since the fax status key was pressed. If not, the process proceeds to S6-6 to select one item in the list and its detailed information. Is determined, and if there is an instruction to display, the process proceeds to the flowchart of FIG. If not, the process proceeds to S6-7, where it is determined whether or not the return key has been pressed. If the return key is pressed, the process proceeds to S6-8, where all the transmission prohibition flags are turned OFF and the suppression of transmission start is released. In S6-9, the screen returns to the basic screen of FIG.
[0044]
If one item in the list is selected during the display of FIG. 3B in S6-6 and the detailed information key is pressed, the process proceeds to S7-1, and the transmission prohibition flag of the selected item remains ON and the others Turn off the transmission prohibition flag for. In S7-2, detailed information about the selected item is displayed as shown in FIG.
[0045]
Next, in S7-3, it is determined whether or not change processing such as correction, deletion, and addition of the destination and transmission start time is performed on the displayed matter, and the change processing is performed by pressing the change key on the screen of FIG. When the process is performed, the process proceeds to S7-4, and the change process is performed as shown in FIGS. If it is detected in S7-5 that the change process has been completed, such as when the OK key is pressed on the screen of FIG. 3F, the process proceeds to S7-6, and the transmission waiting stored in the image storage unit 1-2 is awaited. The transmission prohibition flag for the image data is turned OFF, and the screen returns to the basic screen as shown in FIG. 3A in S7-7.
[0046]
Next, the flow of operations when transmitting the image data stored in the image storage unit 1-2 will be described with reference to the flowchart shown in FIG.
[0047]
First, in S8-1, it is checked whether the management block is linked to the communication reservation queue (whether the address is stored). If there is a management block, it is checked in step S8-2 whether the transmission prohibition flag for the image data corresponding to the management block set at the head of the communication reservation queue is ON. If the transmission prohibition flag is OFF, the process proceeds to S8-3, and this image data management block is linked to the call queue provided in the RAM 1-6-3 as shown in FIG. Set the address and memorize it). On the other hand, if the transmission prohibition flag is ON, the process proceeds to S8-4, and the transmission prohibition flag for other transmission-waiting image data (stored in the image storage unit 1-2) is checked. Proceeding to 5, the head management block whose transmission prohibition flag is ON is re-linked to the end of the communication reservation queue. In S8-6, the next management block set in the communication reservation queue is linked to the call queue as shown in FIG. 9B. If it is determined in S8-4 that the transmission prohibition flag is ON for all transmission image data, the process returns to S8-1 because the image data cannot be transmitted, and the process is repeated.
[0048]
In step S8-7, image data is transmitted based on the management data set in the call queue by a known facsimile standard transmission procedure. When the transmission ends normally, the process proceeds to S8-8, and the management block address for the transmitted image data is deleted from the call queue. In step S8-9, the management block for the transmitted image data in the RAM 1-6-3 is initialized, and the image data is deleted from the image storage unit 1-2. Thereafter, the above process is repeated.
[0049]
As described above, according to the present embodiment, the communication reservation status can be displayed on the operation unit 1-5 by the operation of the operator and can be confirmed as appropriate, and the communication reservation is canceled or changed (performed). Or transmission start can be suppressed for matters that are being processed for cancellation or change.
[0050]
In addition, since the above change processing is performed by sequentially switching the display using a touch panel method, the processing is easy, and a display that is also used as a display for other purposes can be obtained.
[0051]
The operation flow described above (the flowcharts in FIGS. 4 and 6 to 8) is controlled by the CPU 1-6-1 based on the program stored in the ROM 1-6-2. The program stored in may be stored in a removable storage medium such as a floppy disk so that it can be used in other devices.
[0052]
【The invention's effect】
As described above, according to the present invention, when the change processing mode is set, transmission of data whose parameters should be changed is not started, so that erroneous transmission can be prevented.
