Abstract

PURPOSE:To read accurately information on forms with use of a simple device by using a means which detects the size of the form carried to a picture reading part based on the form detecting signal received from a detecting means and decides whether the relevant form is equal to a read form or a mark sheet form. CONSTITUTION:The forms set at a paper feed part 3 are sent to a paper feed roller 4 at and after the lowest form by a resist roll (not shown here) by matched timing. Then the roller 4 sends the form to a picture reading station 5. An optical switch 6 consisting of a light emitting element 6a and a light receiving element 6b is provided between the station 5 and the roller 4. When the carried form cuts off the light received from the element 6a, the element 6b delivers the paper detecting signal (h) to the processing part 20 of a picture reading controller. The part 20 counts the level changing frequencies of the input signal (h) and decides whether the length of the form is equal to (a) or (a+alpha), i.e., the carried form is equal to a mark sheet form 2 or a read form 3.

That is.

[Summary of the invention]

The electronic filing device according to the present invention reads and records an image of a reading sheet conveyed to an image reading section, and
Prior to transporting the reading paper, search information on the mark sheet paper that has been read and recorded by the image reading unit is added to the recorded information on the reading paper, and based on this search information, the image of each reading paper is retrieved. An electronic filing device capable of extracting information, the device comprising: a detection means provided in a conveyance path for conveying paper to the image reading section and detecting the presence or absence of conveyed paper; and paper detection from the detection means. The present invention is characterized by comprising a means for detecting the size of the paper conveyed to the image reading section based on a signal and determining whether the paper is a reading paper or a mark sheet paper.

[Embodiments of the invention]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 and 2.

In the figure, 1 is a reading paper, 2 is a mark sheet paper, and they are loaded together in the paper feed section 3 with the image display side facing down.
The coded keyword provided on the mark sheet paper 2 is added to the image information of the reading paper 1 stacked above the mark sheet paper 2 by the image reading controller shown in FIG.

The size of the mark sheet paper 2 differs from the reading paper 1 only in the length in the transport direction;
The length in the transport direction is longer than ) by (b).

The sheets stacked in the paper feed section 3 are fed from the lowest layer to the paper feed roller 4 at the same timing by registration rollers (not shown), and the paper feed roller 4 directs the paper toward the image reading station 5. transported. Between the image reading station 5 and the paper feed roller 4, a light emitting element 6 &
An optical switch 6 consisting of a light emitting element 6a and a light receiving element 6b is provided, and when the paper being conveyed blocks the light from the light emitting element 6a,
A paper detection signal is output from the light receiving element 6b to the processing section 20 of the image reading controller shown in FIG. This processing unit 20 counts the level change of the input paper detection signal and determines whether the paper length is a or a+α, that is, whether the transported paper is mark sheet paper 2 or reading paper 3. Determine whether

On the other hand, in the image reading station 5, a slit 8 is provided in the paper conveyance path 7 along the width direction of the paper perpendicular to the paper conveyance direction. The underside of the paper being transported in the direction of arrow A is illuminated by an illumination system that includes a lamp 9 and a lens 10, and the light reflected from the paper is
The light enters the light receiving section 11, which is composed of a D array or the like, and an image is read. Then, the image signal G from the light receiving section 11 is output to the reading section 21 of the image reading controller. Then, the paper that has been read is ejected to a tray (not shown) by the ejection roller 12.

Here, based on the paper detection signal from the optical switch 6,
If the processing unit 2o determines that the paper being conveyed is, for example, a mark sheet paper 2, the image signal G input to the reading unit 21 via the light receiving unit 11 is assumed to be code information, and is stored in the RAM 22. be remembered. When all the code information on mark sheet paper 2 has been read, the RAM
The information of 22 is sent to the recording section 23 as code information and recorded. The conveyance length of the paper sent after the mark sheet paper is also measured by the optical switch 6, and it is determined whether it is mark sheet paper or reading paper, but normally reading paper is 1 is transported. Further, in this embodiment, the code information of the mark sheet paper 2 is provided with information on the number of sheets to be read 1 to be sent next, and the reading of the image information on the read paper 1 is controlled. Therefore, the predetermined number of sheets 1 to be read are sequentially read as image information, and the image information for each sheet to be read is stored in the RAM 22. -The image information stored in the RAM 22 is
The code information read from the mark sheet paper 2 is added and recorded in the recording section 23. After a predetermined number of reading sheets 1 pass through the optical switch 6, another mark sheet sheet 2 passes through the optical switch 6.
It is determined that the mark sheet paper 2 is being conveyed, and the image information to be read next is assumed to be code information, and the same processing as described above is performed.

Then, the image information recorded in the recording section 23 is searched based on the code information given by the mark sheet, and can be output as image information.

In the above embodiment, the length of the paper is detected non-contactly using an optical switch, but a contact type switch that can be turned on and off by just touching the paper is provided in the paper transport section to detect the paper length in a non-contact manner. Alternatively, the length in the feeding direction may be detected.

〔Effect of the invention〕

As described above, according to the present invention, a simple mechanism is used to detect the size of the sheets being conveyed in the conveyance path in which the sheets are conveyed one by one for reading in a group of stacked sheets. Since it is possible to determine whether the information read by the image reading section is image information of the reading paper or search information of the mark sheet paper, it is possible to search for the image information of the reading paper conveyed after the mark sheet paper. The advantageous effect is that the process of adding information can be performed without complicating the device configuration.
