Reference numeral 11 denotes an operation display unit for performing a communication operation, a registration operation, and the like, and includes various keys and a display, and has, for example, a function of designating whether a document to be read is one side or both sides. Particularly, in this embodiment, a hard key for double-sided accumulation (hereinafter, referred to as a double-sided original key; not shown) and an LED (not shown) are linked, and when the double-sided original key is pressed, the corresponding LED is turned on. Then, when the double-sided document key is pressed again, the LED is turned off. That is, by operating the double-sided document key before the document reading operation, information indicating whether the document is a double-sided document or a single-sided document is set, and while the LED is lit, it indicates that the double-sided document is being accumulated. Further, the storage result is configured to be stored while being updated on the RAM constituting the system memory 2.
Alternatively, when the two-sided document key is pressed, a message indicating that the document is a two-sided document (for example, the characters “double-sided”) is displayed on the LCD (for example, a predetermined area on the LCD display surface). The display may be switched to a display indicating that there is (for example, the character “one side”). When the storage process is completed, the history of the double-sided document key may be discarded to return to any state. Note that these settings may be held as internal switches in the system memory 2 and arbitrarily switched by a switch setting operation or the like.
[0008]
In the present embodiment, for example, when reading ten originals, if the third and ninth originals are double-sided originals and the other originals are single-sided originals, press the two-sided original key for the first original. Without one side. At this time, if the display is on both sides, the double-sided document key is cleared. Thereafter, for the third sheet, a double-sided document key is pressed between the start of reading of the second sheet and the start of reading of the third sheet to instruct both sides. For the fourth sheet, the double-sided document key is cleared during the period from the start of reading of the third sheet to the start of reading of the fourth sheet, and one side is designated. Thereafter, for the ninth sheet, the two-sided document key is pressed to designate both sides, and for the tenth sheet, the two-sided document key is cleared and one side is designated. By such an operation, “first sheet: one side”, “second sheet: one side”, “third sheet: both sides”, “fourth sheet: one side”, “fifth sheet: one side”, “sixth sheet” : One side, “seventh side: one side”, “eighth side: one side”, “ninth side: both sides”, and “10th side: one side” are stored.
[0009]
Next, the handling of documents in the image memory 9 will be briefly described with reference to FIG.
In this embodiment, the required number of document management tables 20, page management tables 30, and destination management tables 40 are provided in the system memory 2. In the document management table 20, various parameters for handling a document, for example, a document number 21, a document type 22, a creation date and time 23, and the like are set. Among them, the first page pointer 26 is a pointer indicating the page management table 30 of the first page of the document when the document is stored in the image memory 9. The next page pointer 35 is sequentially used as described above. In the page management table 30, other parameters such as the size 31, the line density 32, and the code mode 33 of the stored document, the image pointer 34 indicating the actual storage position of the document, and the like are set. Similarly, the destination can refer to the destination management table 40 with the pointer 27 of the first destination, and the simple code 41, the execution result 42, the next destination pointer 43, and the like are set therein. When there is no next page or when there is no next destination, “NULL” indicating the end is set in the next page pointer 35 and the next destination pointer 43.
[0010]
Next, referring to FIG. 3, a transport path at the time of reading in this embodiment will be described.
In this embodiment, two drive motors (MOTOR (1) and MOTOR (2)) are provided, the document is set with the document side up, and reading is performed from the first page (illustrated as p.1). Separation is performed by the pickup roller R (p), and one document can be transported to the pre-feed roller (Rfeed). In the pre-feed processing, the leading end of the document is brought to a position + α detected by the sensor S (2) ahead of the roller R (1). The sensor S (1) is for checking the presence or absence of a document, and the sensor S (0) is mainly used for checking the document JAM because the transport path to the sensor S (2) is long. When the feed is started, reading is performed while the front surface reading sensor S (4) indicates that there is a document.
In the case of a double-sided document, the back side reading by the back side reading sensor S (5) is performed in parallel with a slight delay. Also, if necessary, when the stamp function by the completed stamp 50 is ON, both the completed stamps 50 can be pressed to the vicinity of the trailing edge of the original in the case of one-sided original and in the case of one-sided (lower) double-sided original. A recent reading sensor is a CCD integrated with a xenon lamp and is called a contact sensor. Also, in FIG. 3, R (0) and Rexit indicate transport rollers, and S (3) indicates a manual feed set sensor.
[0011]
Next, a process of reading / accumulating a one-sided original in this embodiment will be described.
In the present embodiment, information read by the scanner 3 is raw or compressed by the encoding / decoding unit 10 and stored in the image memory 9. Further, whether the original to be read is one side or both sides is indicated by the operation display unit 11 as described above. At this time, basically, the selection is made on a file basis, and when a single-sided original and a double-sided original are mixed as described above, the "double-sided" and "single-sided" can be switched among the files using the double-sided original key. It is configured as follows. In this embodiment, as an accumulation display method using LEDs at the time of single-sided / double-sided reading, in the present embodiment, the method A shown in FIG. (C) at the time and (d) at the time of double-sided original. On the single-sided storage display screen 701 and double-sided storage display screen 702 according to the A method, the remaining memory capacity, single / double-sided discrimination, the number of pages, and the file number are displayed. In the single-sided accumulation display screen 703 and the double-sided accumulation display screen 704 in the B method, the remaining memory, the number of pages, and the file number are displayed, and the distinction is not made between single-sided / double-sided, but by the number of pages. Then, in the case of both sides, the number of pages is displayed as "1 & 2"). Note that a parameter group for performing such display is stored in the system memory (RAM) 2 as shown in FIG. In FIG. 5, (A) is a parameter group in the A method, and the image 720 of the argument of the display process at the time of single-sided / double-sided reading includes the file number 711, the remaining memory 712, the number of pages 714, and the single-sided / double-sided. Distinction) 715. (B) is a parameter group in the B method, and the image 730 of the argument of the display processing at the time of one-sided / two-sided reading includes a file number 711, a remaining memory amount 712, and the number of pages 716, 717 on the front and back sides. In the case of one side, the page number 717 is “NULL”. (C) is an image 710 of the argument of the display processing at the time of the single-sided reading in the conventional method, which is composed of the file number 711, the remaining memory 712, and the number of pages 713, and the parameter for displaying the single-sided / double-sided is Do not have.
[0012]
In this embodiment, as shown in FIG. 6A, when the accumulation is started, the related part is first initialized (step 401), and the file is opened (step 402). This means that the document management table 20 on the system memory 2 is newly allocated for storage, and the document number 21, the document type 22, the creation date and time 23, and the like are set at this time. Next, a page counter (not shown) is set. It is assumed that the page counter value of this embodiment is allocated in the system memory 2 and has been initialized to "0" in the above-described initialization processing. The parameter group for displaying such a storage process is as shown in FIG.
Next, if there is a document, pre-feed is performed as described with reference to FIG. 3 (step 403).
Next, whether the original is single-sided or double-sided is referred to from a RAM (system memory) storing the state of the double-sided original key, and the process branches to a target reading mode (step 404). As a result, the page counter is incremented by "+1" for one side (step 405), and the page counter is incremented by "+2" for both sides (step 410).
Next, an accumulation process is performed while reading the original (steps 406 and 411).
[0013]
The outline of this step 406 is as shown in FIG.
That is, in the case of a one-sided original, the opening process of one page (table) is performed in this embodiment as in the related art (step 431). At this time, one page management table 30 is newly assigned, and the pointer 26 of the first page of the document management table 20 is pointed to this. In the page management table 30, a size (accumulation width) 31, a line density 32, and a code mode 33 are set. The size 31 is detected by a document width sensor (not shown). Note that the document width sensors are located near the sensor S (1) shown in FIG. 3 and are usually provided two in order to recognize A4 width to B4 width to A3 width. That is, it is determined that both of the two document width sensors are A4 when both are OFF, A3 when both are ON, and B4 when one side closer to the center is ON. The line density 32 is selected by a user operation, and reflects the specified one. The code mode 33 includes raw / MH / MR / MMR, etc., but is usually service switching, and reflects the set contents. Further, the start address of the image memory to be actually used is stored in the image pointer 34.
When the above processing is completed, the image is read line by line, encoded, and stored in the image memory 9 (step 432). Note that this accumulation processing is a known technique and is not a main part of the present invention, so that the description thereof is omitted. After the reading / accumulating process for each page (Step 432) is completed, a page closing process (Step 433) is performed. Here, the next page pointer of the above-described page management table 30 is provisionally set to NULL in the sense of terminating the processing.
[0014]
On the other hand, the outline of step 411 is as shown in FIG. In the case of a double-sided document, the necessary parameters also change naturally in the initialization processing, but the reading / accumulation processing will be described here.
That is, if the document is a two-sided document, the table is first handled in the same manner as in the above-described page open processing (step 421). Further, one page management table 30 is allocated to perform the back page open processing (step 422). In this case, the next page pointer of the table needs to point to the back page management table. For example, here, the reading mode is treated as the same for the front and back sides, and the same value is set for the size, line density, and code mode of both page management tables. In the above processing, the information up to the second page is set in the file management even though the actual reading is not performed.
Next, reading / accumulating processing (front and back) is performed (steps 423 and 424). In this case, information that is actually read optically is raw, and a method is known in which the information is sequentially stored in a line buffer (not shown) or the like, encoded by the encoding / decoding unit 10, and stored in the image memory 9. . In the present embodiment, two line buffers are provided, and the encoding / decoding unit 10 is configured to have two line buffers or to be switched in line units. With the above arrangement, image processing paths are formed separately for the front and back sides. As a result, information for two pages is stored in the image memory 9 almost simultaneously. Here, the one obtained from the storage path of the front is stored as “page 1”, and the one obtained from the back is stored as “page 2”.
After the reading / accumulating process on both the front and back sides (steps 423 and 424) is completed (normally, the process on one side is completed early), the front and back page closing processes are performed (steps 425 and 426). Also in this page closing process, the second next page pointer (the next page pointer of the back page in step 426) is set to NULL.
With such control, the front and back sides of a double-sided document can be read simultaneously and stored almost simultaneously. In the above-described single-sided / double-sided original reading / accumulating processing, the original which is stored as one file is determined by judging before reading the original from the contents reflecting the instruction of the double-sided original key in units of originals based on the contents reflecting the instruction of the double-sided original key. Even if single-sided / double-sided originals are mixed, files can be properly stored and managed.
[0015]
After the reading / accumulating process, if there is no next original (No in step 407), a file closing process is performed (step 408), and the accumulating process ends. In the file closing process, a page counter is set in the document management table 20, and a setting (not shown) indicating that the accumulation is completed and the transmission is on standby is performed. On the other hand, if there is the next original (Yes in step 407), the process returns to step 404, and the process is performed again for each page. In this case, for the second and subsequent pages, the next page pointer 35 of the previous page management table 20 is set to point to the next page management table.
[0016]
(Second embodiment)
FIG. 7 is a diagram showing a procedure for reading / accumulating single-sided / double-sided originals and display contents according to the second embodiment of the present invention, which corresponds to the first embodiment (FIG. 6).You.The basic configuration (FIGS. 1 to 3) and functions shown in the first embodiment are the same in this embodiment. In the first embodiment, it is necessary for the operator to issue a one-sided / two-sided switching instruction. In this embodiment, however, the communication terminal having the image reading apparatus shown in the first embodiment is a communication terminal. An apparatus which can provide the same effect as that of the first embodiment even when an instruction to send a message is given at the communication terminal without an operator during the accumulation process.
In the present embodiment, operations (one-sided / two-sided instructions, instructions to add a sending slip, etc.) on the operation display unit (11 in FIG. 1) during memory storage are performed by menu selection using numeric keys or the like on the LED display screen. The configuration is as follows. That is, the LED itself is used as a touch panel, and when a display portion on one or both sides is pressed, the display portion is inverted. Also, in this embodiment, it is not assumed that the one-sided / two-sided switching is performed frequently as in the first embodiment, and the case where the sending slip and the final document are odd-numbered pages is treated as an exception. For example, as shown on the LED display screen 502 in FIG. 7B, when the operation display unit (11 in FIG. 1) is used to input data to a destination when storing data in the memory, the down scroll key ( (Not shown) to proceed to an option selection screen (LED display screen 503 in FIG. 7B), where an instruction for a double-sided original and an instruction for a sending slip are performed. When the setting is completed, the user presses the down scroll key to complete the setting and returns to the screen 502. That is, a menu is selected with a numeric keypad or the like when making each selection, and when a menu is selected, selection is made as necessary with left and right scroll keys or the like.
[0017]
Next, with reference to FIG. 7A, the sending slip adding process according to the present embodiment will be described. Also in the present embodiment, it is assumed that both sides or one side is designated for each file, and for the sake of simplicity, the description of the same parts as in the first embodiment will be omitted.
In the present embodiment, in step 510, if the document is a single-sided document, all the documents are read as a single-sided document regardless of the presence or absence of a sending slip. Conversely, if the original is not a single-sided original, the page is first evaluated by the page counter (if the original is the original, it is evaluated because the result of the initialization process 402 is “0”). In this case (when the document is the first document), the above-described function selection information is further read to determine the presence or absence of a sending slip. If both conditions are satisfied (Yes in step 510), the document is read as a single-sided original regardless of whether the double-sided original is being read (steps 405 and 406). On the other hand, if the document is a two-sided document and there is no transmission form (No in step 510), it is determined that the document is a two-sided document, and both sides are read / stored in the same manner as in the first embodiment ( Steps 410 and 411). By adding the above-described determination, mixed originals of both sides / one side (sending table) can be sequentially read / stored.
[0018]
In addition, since the stored document management is performed by one page open and one page close when sending a single-sided form, only one page management table is prepared. Therefore, two page management tables are prepared at a time. Also, in the page counting process (steps 405 and 410), since the above determination is reflected, control is made so that "+1" is set for a sending slip and "+2" is set for a double-sided original.
According to the present embodiment, there is no need to read an invalid page behind the sending slip, so that quick memory transmission, which is increasing in number recently (proceeds with the partner connection processing simultaneously with the accumulation processing, and transmits image information after reading P1) ).
[0019]
(Third embodiment)
FIG. 8 is a diagram showing a procedure for reading / accumulating single-sided / double-sided originals and display contents according to the third embodiment of the present invention, which corresponds to the first embodiment (FIG. 6).You.The basic configuration (FIGS. 1 to 3) and functions shown in the first embodiment are the same in this embodiment.
In the first embodiment, the operator needs to issue a one-sided / two-sided switching instruction. In the present embodiment, however, the communication terminal having the image reading apparatus shown in the first embodiment is a communication terminal. In the case where the last document is a single-sided document (odd-numbered pages) when a double-sided document is stored in a terminal, an apparatus similar to that of the first embodiment can be obtained without an operator during the storing process.
[0020]
In the present embodiment, an operation on the operation display unit (11 in FIG. 1) (an instruction when the last page of a double-sided document is single-sided) during memory storage is performed by menu selection using a numeric keypad or the like on the LED display screen. The configuration is as follows. For example, in the LED display screen 602 in FIG. 8B, when the destination is input at the time of memory storage, a down scroll key (not shown) is pressed to transit to an option selection screen (LED display screen 603). I do. On this screen 603, ten keys (not shown) "0" and "3" are depressed, and a transition is made to an input screen 604 for the number of documents. In this screen 604, the ten key “9” is pressed to move to the screen 605, and in this screen 605, Yes is selected and the screen returns to the screen 603. Further, a configuration is provided in which selection completion is pressed on the screen 603 and the screen returns to the screen 602.
[0021]
Next, a procedure for designating the last single-sided page of this embodiment will be described with reference to FIG. Also in this embodiment, it is assumed that both sides or one side are designated for each file, and the fact that the document is a two-sided original is determined by setting of the system memory (RAM). Description is omitted.
In this embodiment, in step 610, when a two-sided original is set, whether or not the original is the last one is evaluated based on the page counter (result of the page count process 405) and the above-mentioned instruction for the number of originals (the number of pages for two-sided originals). At this time, it is determined whether or not the latter is an odd number. If the latter is an odd number and <the former counter = page count>, it is determined that the original is the final document. If this condition is satisfied (Yes in step 610), the original is read as a single-sided original regardless of whether the original is being read. If not (No in step 610), it is determined that the document is a double-sided document, and reading / accumulation of both sides (steps 410 and 411) is performed as in the first embodiment. By adding the above judgment, mixed originals of both sides / one side (the last page is blank) can be sequentially read / stored.
[0022]
In addition, since stored document management is performed by one page open / page close when sending a single-sided form, a single page management table is prepared. Since this is implemented, two page management tables are prepared at once. In addition, since the above determination (step 610) has already been made in the page count processing (steps 405 and 410), if the final document is single-sided (the number of pages is odd), it is set to "+1". Needless to say, “+2”.
[0023]
Also, the page counter being processed has the same value in any case (whether the last page is an even number or an odd number), but the total counter of the accumulated page has a different value between the odd number and the even number. The page counter during the processing is used for display during execution or the like. For example, when reading the second sheet of a two-sided original, the page counter is usually 3 pages and 4 pages, and is displayed as 3 pages (the initial value is “ 1 + 2), but in practice, processing is performed for up to four pages, so the total counter of accumulated pages must be treated as four pages. Hereinafter, a more specific description will be given. For example, when there are five double-sided originals and the final original is single-sided, “8” (number of sides × 4) is increased by “+1” to “9” in the page counting process (step 405), and the screen shown in FIG. 701 or the screen 703 is displayed. On the other hand, when the final document is double-sided, “8” (number of sides × 4) is increased by “2” to “10” in the page counting process (step 410), and the screen 702 or the screen 704 shown in FIG. I do. That is, in the case of the single-sided printing in the A method, the arguments are notified as the page number 714 shown in FIG. 5 = “9” and the single-sided / double-sided 715 = “single-sided”. In the case of both sides in the A method, the arguments are notified as the page number 714 shown in FIG. 5 = “9” and one side / two sides 715 = “one side”. In the case of single-sided printing in the B method, the arguments are notified as the page number 716 = “9” and the page number 717 = “NULL” shown in FIG. In the case of both sides in the B method, the arguments are notified as the page number 716 = "9" and the page number 717 = "10" shown in FIG.
[0024]
(Fourth embodiment)
FIG. 9 is a diagram showing a procedure for reading / accumulating single-sided / double-sided originals according to the fourth embodiment of the present invention, which corresponds to the first embodiment (FIG. 6).I do.The basic configuration (FIGS. 1 to 3) and functions shown in the first embodiment are the same in this embodiment. Further, in the present embodiment, a case may occur in which a double-sided document and a sending slip are mixed as in the second embodiment, and the presence or absence of the sending slip is given from the operation display unit separately from the instruction as to whether the original is single-sided. Shall be.
In this embodiment, as shown in steps 810 and 811, the sending slip check and the one-sided original instruction check are separately performed. For this purpose, as shown in FIG. 10, the document management table 20 has a pointer 25 for the sending slip, and the page management table 30 'pointed to by the pointer 25 stores the sending slip parameter 60. If there is a sending slip, the pointer 25 points to the sending slip page management table 30 ', and if there is no fingering slip, "NULL" is set here. Normally, the number of transmission slips is one (one side), and the next page pointer 35 in the page management table 30 pointed to by the pointer 26 of the first page is “NULL”. Also, as described above, since the transmission form is a one-sided original, if there is a transmission form in the above determination (Yes in step 810), the process proceeds to steps 405 and 406 and is read as a one-sided original.
Note that the display switching timing of the LED screen is T₁, T₂As shown in FIG. The display switching timing is the same as in each embodiment.
[0025]
(Fifth embodiment)
FIG. 11 is a diagram showing a procedure for reading / accumulating single-sided / double-sided originals according to the fifth embodiment of the present invention. The basic configuration (FIGS. 1 to 3), the accumulation display function, and the like shown in the first embodiment are the same in this embodiment. In particular, the present embodiment shows a method for effectively performing the preheating operation of the xenon lamp constituting the scanner without waste.
If it is determined in step 1001 that the document is a double-sided document, it is necessary to provide a residual heat (pre-heat) time (about 1 second even if the stabilization time is short) for the xenon lamp regardless of the presence or absence of the sending slip. For example, when the first document is pre-fed (step 403 in FIGS. 7 to 9) as in the second to fourth embodiments and then preheated, the start of reading the first document is delayed. Therefore, in the present embodiment, even if the document is a duplex document and there is a sending slip (the actual sending slip reading is one-side reading), both upper and lower xenon lamps are always preheated in accordance with the first document reading process. (Step 1003). By this control, complicated processing is avoided, and a stable light amount is provided from the beginning without performing extra wait time processing. In the case of a single-sided document, only the front xenon lamp is preheated.
[0026]
If the last original is single-sided while reading the double-sided original (Yes in Steps 1004 and 1005a, Yes in 1005b, and Yes in 1005c), the state of the xenon lamp for the back side is set to OFF (turned off) (Step 1006). . This is for the following reason. For example, in the third embodiment, if the last original is single-sided while reading the double-sided original, single-sided reading is performed.Xenon lampIn the case where the final document is single-sided while reading a double-sided document, the light intensity of the xenon lamp on the back side has no meaning, and turning off the back side can extend the life of the xenon lamp on the back side. it can.
Note that the processing in step 1004 corresponds to, for example, steps 810, 811, 405, and 410 shown in FIG. 9, and in this embodiment, skip processing between steps 405 and 410 and steps 406 and 411 (steps 1005 and 1006). Is addedYou.
