Description of the Related Art Conventionally, in an information reading apparatus in which information of a document is read by a reading unit and is taken out as image data, the reading unit is moved in one direction with respect to the document to read the information of the document. The image data of the read original is temporarily stored in the storage unit.

That is, in the conventional information reading apparatus, the reading section is moved from the reading start position to the reading end position of the information of the original to read the original, and then the original is read in order to read the next original. Is configured to return the reading unit to the reading start position of the information of
The original is not read during the period in which the reading unit is returned.

By the way, if the document is read only when the reading unit moves in one direction, the user can read the information of the original document at the reading start position for reading the next document. You have to wait while you are moving to.

Therefore, a configuration is conceivable in which the reading unit reads the next original during a period in which the reading unit moves to the reading start position of the information of the original original for reading the next original, as shown in FIG. 5A. If the reading unit reads such document information during the period for the reading unit to return to its original position, the document information shown in FIG. 5A will be read from below the page. Therefore, in this case, the image data is stored in the storage unit in the order shown in FIG. 5B, and if the image data is read from the storage unit as it is, the information array of the document shown in FIG. It is necessary to use the read image data output in the opposite arrangement to the arrangement opposite to the arrangement of the original document information as shown in FIG. 5B.

[0006]

As described above, in the conventional information reading apparatus, the moving direction of the reading unit for reading the information of the original document is limited to one direction. In this case, the reading unit is the original document. After moving to the information reading end position, the user must wait until it returns to the original information reading start position for reading the next original information, and during this time, the next original When the information is read, the reading is performed in the reverse reading order to the reading order of the information of the previous document, which causes a problem that the read information cannot be normally output.

Therefore, according to the present invention, the reading section is moved in both directions with respect to the original to read the information of the original,
An object of the present invention is to provide an apparatus capable of always obtaining image data in a fixed order regardless of the moving direction of the reading unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the information reading apparatus of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the information reading apparatus of the present invention. An information reading apparatus according to an embodiment of the present invention shown in FIG. 1 has a reading unit 4 for reading information of a document on a bus (which is composed of an address, a control and a data bus) 2 connected to a control unit 1 which is a microcomputer, and a data unit. A memory 5 having a forward conversion unit 6, a facsimile control unit 7 for receiving information transmitted from the other party via the line 8 or transmitting information to the other party via the line 8, and transmitted from the other party via the line 8. A recording unit 9 for recording the recorded information and an operation unit 3 for performing various operations are connected.

Here, the reading unit 4 is, for example, a light emitting unit or a CCD.
Etc. and an unillustrated drive unit for driving the optical sensor. The unillustrated drive unit moves the optical sensor bidirectionally with respect to the document, and the optical sensor emits light from the light emitting unit. The information of the original is read by detecting the reflected light, and the image data is output to the bus 2.

The memory 5 has a data order conversion unit 6 inside.
The data conversion unit 6 writes the image data supplied from the reading unit 4 via the bus 2 into the memory 5, and at the same time, the memory 5 responds to the control signal supplied from the control unit 1 via the bus 2. The image data is read from the memory 5 in the same order as when the image data was written in or in the reverse order.

The recording unit 9 is composed of, for example, a printer, a magnetic tape device, or the like, and prints or magnetically prints on the paper the transmission information from the destination received by the facsimile 7 via the line 8 or the information of the original read by the reading unit 4. Record on tape. The operation unit 6 is composed of various input switches such as a copy start switch and a start / stop switch for the user to operate.

Before explaining the operation of the information reading apparatus shown in FIG. 1, the reading operation of the reading section 4 will be described with reference to FIG. FIG. 3 shows the original table 10 and the reading unit 4 mounted in the original table 10. As shown in FIG. 3, from the position of the reading unit 4 shown by the solid line to the position of the reading unit 4 shown by the broken line. Assuming that the moving direction x is a positive movement, the position of the reading unit 4 shown by the broken line is changed to the reading unit 4 shown by the solid line.
The movement direction y up to the position is the movement in the opposite direction. As shown in FIG. 3, when reading information on a document (not shown) placed on the document table 10, first, the reading unit is moved in the forward direction indicated by arrow x in the figure to read the information on the first document. Then, the reading unit is moved in the opposite direction indicated by arrow y in the drawing to read the information of the next document. That is, the reading unit 4 reads the information of the document in either forward or reverse directions.

Next, the operation of the information reading apparatus shown in FIG. 1 will be described. First, the image data obtained by reading the information of the original document by the reading unit 4 is transmitted to the other party through the line 8 by the facsimile control unit 7. In this case, the image data obtained by reading the information of the document by the reading unit 4 is supplied to the memory 5 via the bus 2, and the image data is temporarily stored in the memory 5. When reading the image data from the memory 5, the data order of the image data is converted and read by the data order conversion unit 6 when the reading direction is the reverse direction when the image data to be read is read. The read image data is supplied to the facsimile control unit 7 via the bus 2. In the facsimile control unit 7, for example, this image data is encoded, and then the encoded image data is supplied to the line 8
Through the device of the other party.

Next, when the image data obtained by reading the information of the original document by the reading unit 4 is recorded by the recording unit 9, the reading unit 4
The image data obtained by reading the information of the original document is supplied to the memory 5 via the bus 2, and the image data is temporarily stored in the memory 5. When reading the image data from the memory 5, the data order of the image data is converted and read by the data order conversion unit 6 when the reading direction is the reverse direction when the image data to be read is read. The read image data is supplied to the recording unit 9 via the bus 2, and the recording unit 9 prints or transfers the image data onto, for example, paper.

Next, when the recording unit 9 records the information transmitted from the destination via the line 8, the facsimile control unit 7 decodes the encoded information transmitted from the destination via the line 8. To return to the original information, and use this information on bus 2
It is temporarily stored in the memory 5 via. And this memory 5
The information read out is supplied to the recording unit 9 via the bus 2 and the recording unit 9 prints or transfers the information on, for example, paper.

Next, referring to the flowchart of FIG.
The operation of the information reading apparatus of this embodiment shown in FIG. 1 will be described. When the user presses a copy start switch (not shown) of the operation unit 3, the so-called copy operation described below is started.

First, at step 100, Fl = 0 is set. Then, the process proceeds to step 110. Here, Fl is a flag indicating the next reading direction, that is, the direction in which the reading unit 4 moves is the forward direction or the reverse direction. The movement direction of the reading unit 4 at the start of the operation is the positive direction. The flag Fl becomes "0" in the movement in the direction, and the flag Fl becomes "1" in the movement in the direction opposite to the movement direction of the reading unit 4 at the time of starting the operation.

In step 110, it is judged whether or not a start switch (not shown) of the operation section 3 is pressed by the user. If "YES", the process proceeds to step 120,
If “NO”, the process proceeds to step 130. In step 120, it is judged whether or not the flag Fl is "0", and "YE
If "S", the process proceeds to step 140, and if "NO", the process proceeds to step 150.

In step 130, it is judged whether or not a stop switch (not shown) of the operation unit 3 is pressed, and "YE
If “S”, the process ends, and if “NO”, step 1 again.
Go to 10.

In step 140, reading in the forward direction is set. Then, the process proceeds to step 160. That is,
A control signal is supplied to the data conversion unit 6, and the reading direction from the memory 5 is set to the forward direction.

In step 150, reading in the reverse direction is set. Then, the process proceeds to step 160. That is,
A control signal is supplied to the data converter 6 to set the reading direction from the memory 5 to the reverse direction.

In step 160, it is determined whether or not the reading is completed. If "YES", the process proceeds to step 170. That is, the reading unit 4 is moved until the position of the reading unit 4 reaches a predetermined end position to read the information of the document. The image data obtained by this reading is the bus 2
Is supplied to the memory 5 and written in the memory 5.

At step 170, the take-out start position is set. Then, the process proceeds to step 180. That is,
The reading start position of the image data stored in the memory 5 is set.

In step 180, the flag Fl is inverted. Then, the process proceeds to step 190. That is, since the moving direction of the reading unit 4 for reading the information of the next document is opposite to the moving direction of the reading unit 4 for the current reading, the flag Fl is reversed.

In step 190, recording is started. Then, the process proceeds to step 200. That is, the image data read from the memory 5 is supplied to the recording unit 9 via the bus 2, and the recording unit 9 prints or transfers the image data as an image on, for example, paper. In step 200, it is determined whether or not the recording is completed. If "YES", the process proceeds to step 110 again. Next, with reference to FIG. 4, the operation in the case where the reverse reading is set to the data order conversion unit 6 will be further described.

FIG. 4A is an example of an original, and the reading unit 4 is moved in the reverse direction of moving the reading section 4 from the upper side to the lower side of the original, that is, in the reverse direction of moving the reading section 4 from the lower side to the upper side of the original. In this case, as shown in FIG. 4A, the information of the manuscript is displayed from the bottom by 1 line, 2 lines, 3 lines to n-1 line,
It will be read in the order of n lines. Therefore, in the memory 5 shown in FIG. 1, the information read in the reading order of the information of the document shown in FIG. 4A remains the same as the (input order) on the left side of FIG. 4B. 1 line, 2 lines, 3 lines to n−1, n are input in this order, and if the address of the memory 5 is increased from the top to the bottom in the figure, the memory 5 has the following addresses:
The information "a" of the original document shown in FIG. 4A is stored in an inverted state.

Therefore, as shown on the right side of FIG. 4B as (output order), 1 line, 2 lines, 3 lines to n-
Reading is performed in order of 1 line and n line, that is, from a large address of the memory 5.

After this reading is performed, the read information is supplied to the recording unit 9 via the bus 2, and when the recording unit 9 prints or transfers on paper, for example, 1 line and 2 lines are shown in FIG. 4C. As indicated by 3 lines to n-1 lines and n lines, the information can be output in the same order as the reading order of the information of the document shown in FIG. 4A. In addition, the information of the read manuscript is transferred from the facsimile controller 7 to the line 8
Even when the data is transmitted to the other party through the same as in FIG.
The output can be made in the device of the other party in the order shown in.

As described above, in this embodiment, the reading unit 4 is moved in both the forward and reverse directions with respect to the original to read the information of the original, and at the time of reading the image data stored in the memory 5, Since the reading order is reversed between the image data read by moving the image reading unit 4 in the forward direction and the image data read by moving the reading unit 4 in the reverse direction, the waiting time for the user is significantly reduced. In addition, it is possible to greatly reduce the reading time of the information of the original document and to always output the information of the original document in a fixed order, which eliminates the need for the user to perform troublesome work such as realigning the original document.

In this embodiment, when reading the image data stored in the memory 5, the image reading unit 4 is moved in the forward direction and the read image data is moved in the opposite direction. The case where the reading order is opposite to that of the read image data has been described. When writing the image data obtained by reading in the memory 5, the image reading unit 4 is moved in the forward direction and the read image data is read. Even if the writing order is reversed for the image data read by moving the unit 4 in the opposite direction, the same effect as described above can be obtained. In this case, the order of reading the image data from the memory 5 is the same in either forward or reverse directions.

Although the memory 5 is provided with the data sequence conversion unit 6, for example, the control unit 1 is provided with the data sequence conversion unit 6 to temporarily store the image data obtained by reading in the memory 5, and thereafter The image data stored in the memory 5 may be fetched into the data order conversion unit 6 and may be stored in the memory 5 again by changing the arrangement order of the image data. In this case, the order of reading the image data from the memory 5 is the same in either forward or reverse directions.

[0035]

As described above, according to the present invention,
The first image information obtained by the reading unit moving from the first position to the second position or the second image information obtained by the reading unit moving from the second position to the first position. At least one page of image information is stored in the storage means, and the read control means reads the first image information from the storage means and the second case.
Since the reading order is changed depending on whether the image information is read, the waiting time of the user is significantly reduced, the reading time of the document information is significantly reduced, and the reading section is moved regardless of the moving direction. Thus, the information of the original can be always output in a fixed direction, which has the effect of eliminating the need for the user to perform troublesome work such as rearranging the originals for each page.
