Description

[Detailed Description of the Invention] [Technical Field] Kinoe IJJ relates to an image reading device, especially a portable blood image reading device that performs σjj image reading for each predetermined block. .

[Prior art]

Conventionally, various devices have been reported that read 1W image information using line sensors or contact sensors! ＋、There is.

By the way, when reading a document placed in an arbitrary position using the sensor r, the method of moving the document at a constant speed and reading it by turning the reading device is a method that has been used since then in facsimile machines. are doing. However, in the case of something like this, is it a thick manuscript such as a book? It is difficult to record
There are drawbacks when it comes to equipment size and cost.
The actual fA of portable image recording has been difficult. So, I fixed the manuscript and moved the 11a scanning device! l! I can't think of a way to do it. In some cases, there is no need for a document feeding device, but the layout device can move the document at any speed and in any direction! In the case of 11h-j, there is a problem in reading and extracting two images, and it is necessary to regulate the moving speed and direction of the anti-slip device.As a result, the size of the device has to be increased. Therefore, it becomes unsuitable as a portable image recording device 1t.

By the way, as a method for removing the intermittent marks during 2M reading, reading, etc. of an image of nIJn, a method of recording position information in the image information can be considered. In this case, insert the inserted transparent sheet between the original and the recording device and move the reading device-9. By making it
ft4 recording is also possible.

However, in order to separate and record the image 1 image IR information and the position 1ffi1ff information, it is necessary to integrate the double opening 1~ information and the position information tM (X, Y direction)k, Since there is no difference, I will write about the total number 1. requires a lot of space.

[Purpose J There-C1 Present invention r1, in view of the above points,]) Stripe discharge 7 +11rIM, * it+i: Il'Z device &, U) Remove missing A k and easily I Ka in t
The purpose is to rub rrf rohi.

Furthermore, it is an object of the present invention to prevent both images σ) and read-through.

Furthermore, the purpose of this book is to make it possible to confirm the reading Li (capable II!!i image area).

That is, in a portable image reading device using a light source for document illumination, the image is scanned for each block of a predetermined size, and the reading device is edited into blocks that are scanned and scanned. This feature is characterized in that it assigns a special address.

In addition, a portable image ft7e that can be used as a light source for cool lighting
, a means for reading an image for each block of a predetermined size σ);
'? , has means for distinguishing between the image area that has been seen and the image area that is to be read from t'L.

In addition, a portable image (I
The plate apparatus has means for reading an image for each predetermined thick awn program, and means for displaying an image area read by the reading means.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

Next, when recording the original ru, record the recording area 4'0; verification procedure f, turn on the recording bag inserter 20 and press the copy button 16i to perform image detection as described above. and record all images in memory element 3.Also, even if the operator does not check the image area, if the operator determines that the image area is sufficiently covered, You may record one scan Cu1' by turning on the recording switch 20k.
When the address input capo 22' is set to the IN state, an address number is added to the recorded image and recorded, and at the same time, the address number is outputted from the address input capo 26'. At this time, when outputting the 6 self-recorded image signals according to the 11th address age number recorded, the rearrangement of the 1 Jij image and the re-assembly of the 1 Illll image that was subdivided and recorded becomes the tiJ function. , it becomes possible to record even a document that is thicker than the one-time recording UIJ+product of this image recording apparatus. As mentioned above, when recording an original larger than the recording area of the camera, this recording apparatus moves the original in pressure contact with the original, counts the number of revolutions of the roller 11 using the sound and light source 12 and the light receiving element 13, and records the number of rotations on the original. detects the moving distance of the device at
By displaying the images using the lamp 12, overlapping and skipping of the recorded images can be prevented, and by rearranging and re-editing, the original manuscript can be reproduced. Since the device is equipped with a motor for moving the device over the document, it is also possible to make the device self-propelled and automatically stop the device when it moves vertically or horizontally.

A pulse is generated as the plate device moves from one image to another. Therefore, when the image recording device moves, #'i is input to Po indicating that it is moving. When a signal is input to the PG, it is determined whether there is a clock pulse from the movement clock circuit 34 (S15L) If the movement is in progress, a movement clock is generated, so the movement distance counter is counted every time a clock is generated. Count up (816) and display it on the LED of the travel distance tray address display 26 (817)

Returning to step 1, if the switch settings have not been changed, image capture by CCD K will continue immediately.

However, if the switches are operated again or the image recording device is moved before the recording of one block of images is completed, the image data being recorded will be canceled.

Then, when passing through 821 again, the copy flag has already been set, so the process jumps to S33 and the address number etc. do not change.

In the above embodiment, the image reading device M has a VRAM for storing image information, but this VRAM is moved to the evening side of the host combination 2, and the output from the image reading device M is transmitted via wired communication using a code. If it is sent to the host computer through wireless communication using electromagnetic waves, ICT can also generate a large amount of image information.
