Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an image recording device, and particularly to a portable image recording device having a display unit that directly converts a read image signal into one image and displays the same.

[Prior art]

Conventionally, various devices have been announced that read image information of a document using a line sensor or a contact type sensor. Furthermore, a handheld image recording device is also being considered by incorporating the senna into a portable casing.

By the way, when reading a document placed at an arbitrary position in close contact, a method can be considered in which the reading device is fixed and the document is moved at a constant speed.

However, in the case of such a device, it is generally difficult to record thick documents such as books, and it also requires a device to feed the document at a constant speed, which increases the overall size of the device and makes it difficult to carry. This method is not only unsuitable as a type image recording device, but also has the drawback of increasing costs.

Here, a method can be considered in which the document is fixed without being moved and the reading device is moved. At this time, if the entire document is to be recorded, recording omissions and double recording can be prevented by specifying absolute coordinates (addresses) for the document and having the reading device move while reading these coordinates. However, if the above-mentioned address does not exist, or if you wish to record only part of the document, you will have to move the reading device from one arbitrary position to another.
There is no guideline for this range, and there is a problem in that recording omissions and double recording are likely to occur.

In addition, if there is no means to directly record and output images on the spot (because they are portable, most output is done later), you can display or There is no means for determining this, and there are drawbacks such as the above-mentioned record omission/duplication.

〔the purpose〕

The present invention has been made in view of the problems described below, and it is possible to display recorded images by providing a portable image recording device with a display section that displays an exposed original image. This is intended to prevent the possibility of recording omissions or double recording by making it possible to confirm the information, and also to enable display confirmation of the image range being read by the reading device.

〔Example〕

The present invention will be explained below with reference to the drawings. FIG. 1 is a perspective view showing an example of use of a portable image recording device according to the present invention, and FIG. 2 is a schematic cross-sectional view of the image recording device. 1
is a portable image recording device, 2 is a transparent sheet for detecting positional information, 3 is a document to be recorded, A is the movement (main scanning) direction of the device, and D is a direction of movement of the device.

A swingable liquid crystal display section is shown.

The transparent sheet 2 has a checkered pattern etched on its surface by chemical treatment perpendicular to the main scanning direction A and has a line width of 50 μm.

They are carved at intervals of 8 lines/m. On the other hand, in the sub-scanning direction perpendicular to the main-scanning direction on the document surface, lattice stripes are formed with gradually increasing intervals from the edge of the sheet 2. FIG. 3 shows a locally enlarged surface view of the transparent sheet 2. The intervals between the solar grids are configured to have a difference of one pixel or more in the image sensor 8, which will be described later. That is, the initial interval is a
mm, 1 pixel 1 angle, a r a+11 a+2
The lattice stripes are carved at intervals of 1=·a+nm. The transparent sheet 2 having the checkered pattern etched surface selectively reflects/transmit light depending on the angle of incidence of light.

In Figure 2, 4.6.13 is an LED light source, 5, 5
', 5'' is a lens, 8.8' is an image sensor (CCD) for reading image information, 9 is a control unit 3, 10 is a storage memory, 11 is a power source battery, and 12 is a photosensor.LED Even when the light from the light source 4 is irradiated onto the checkered stripes of the transparent sheet 2, it is incident at an angle (60° or more in this embodiment) that allows the light to be transmitted, and is irradiated onto the original 3.
The reflected light passes through the lens 5 and is recorded on the image sensor 8 as image information.

On the other hand, the light from the L]8D light source 6 is reflected by the lattice stripes of the transparent sheet 2 (in this embodiment, the light is incident at an angle of 30°), and is recorded on the image sensor 8' through the lens 5'. The positional information of the mill in the sub-scanning direction is determined by recording the interval between the lattice stripes in the B direction by using the image sensor 8' to record the reflected light from the LED. Recording in the main scanning direction A is performed by L E l) The light source 13 detects the reflected light from the 8 lines/mm lattice stripes carved perpendicular to the six directions by the photosensor 12 through the lens 5''. Then, the control device 9 of the image sensors 8, 8' is driven, and recording in the main scanning direction A is performed by operating these image sensors 8, 8' at every grid interval.

4- For example, the image sensors 8 and 8' each have n pixels, and each pixel corresponds to an image plane of about 1/8 fin, and has a configuration having a resolution of 8 pels. By activating the image sensors 8 and 8' each time the photosensor 12 detects the 8-tree/III checkered stripes carved in six directions and the vertical direction, one line of n pixels is detected. data can be recorded reliably. Note that each of the above-mentioned LEDs, image sensor, photosensor, control section, and memory are each driven by a battery 11.

As described above, the image information read by the image sensors 8 and 8' is recorded in the memory 10.
memory 10 by arbitrary scanning.

Although it may happen that one piece of image information is recorded more than once, each piece of image information is recorded in a state that corresponds to position information. The image information thus recorded in the memory 10 is aligned and printed based on positional information by an image adjusting device and a printing device (both not shown). However, it is extremely inconvenient because it is not known whether or not the image information has been accurately recorded until the image is output using an image adjustment device or printing device, and in some cases, information may not be obtained due to missing recording. arise.

This risk is quite possible since it is a portable imaging device.

Furthermore, there are cases where there is no address information, cases where scanning is performed by skipping several lines when reading a part of the document, or cases where several lines are double-recorded.

In the former case, especially when you are out and do not have the original at hand, if a recording gap occurs, you will not be able to obtain the information after all, and in the latter case, the number of times you will have to scan the original surface increases, etc. It's a big time loss.

Therefore, in this embodiment, the portable recording device is provided with a liquid crystal display section.

This liquid crystal display method will be explained below. FIG. 4 shows a block diagram showing the circuit configuration of the control device 9 of the embodiment (FIG. 2) of the present invention. This control device includes R, OM, R
It is composed mainly of a well-known one-chip microcomputer CPU 26 that incorporates an AM, and is sequentially controlled by programs stored in a ROM. FIG. 5 is a flowchart showing this control program.

The operation of this embodiment will be explained below using FIGS. 4 and 5. Now, when the operator places the image recording device 1 on the original image surface 3 and the transparent sheet 2 as shown in FIG.

Perform the following operations in sequence. That is, first, the LED light source 1

The reflected light from the above-mentioned checkered stripes is detected by the photo sensor 12 and input to the input port P. It continues to detect whether or not checkered stripes are detected (step 1 in FIG. 5), and if detected, proceeds to the next step.

In step 2, you need to obtain image information and location information (

, and reset the main scanning counter, which will be described later, and then turn on the gate 2 to start storing data from the image sensor 8.8' in the memories 10 and 10'.
Turn on output point (7-) Fs to turn on 0, and proceed to the next step. In the image sensors 8, 8', when the aforementioned LED light source 4.6 is turned on, each reflected light is irradiated onto the image sensor 8.8', and image information and position information are accumulated in each pixel as an analog signal. Ru.

On the other hand, by turning on the gate 20, the reference oscillator (08C
,) 21 is connected to the image sensor 8.8',
Analog signals of each pixel are sequentially read out as serial data. This analog signal is transmitted to the A/D conversion circuit 22.2.
3, the signal is converted into a digital value of predetermined bits, further binarized by a predetermined image signal processing circuit 24, 25, and then input to the memory 10, 10' as video data.

FIG. 6 shows the image/location recording information signal.

Also, by turning on the gate 20, the reference oscillator (O2
The output of 0)21 is input to the input capo) Pt. In step 3, the clock detection from this osc 21 is continued to be monitored, synchronization is performed with the clock present, and address data 8-AD)L8 is determined to determine the address at which the aforementioned video data is stored in the memory 10, 10'. is output from the output port F4, and the W/R signal, which is the write signal for the memo 910, 10', is output from the output port F4.
R, ITB and output from output port F5.
The aforementioned video data is stored in a memory space at a predetermined address. Next, in step 4, the address data is incremented to determine the video data address for the primary pixel, and the image sensor CCD 8.8'
The main scanning counter corresponding to n pixels is incremented, and monitoring is continued until the counter discharges data for all n pixels. If the counter does not complete, the process returns to step 3, waits for the next clock, synchronizes, and repeats the operation of storing video data for the next pixel in the memory. In this way, when the counter ends, recording of image information and position information for one line in the main scanning direction of the image sensor CCD is completed, and the gate 20 is turned off and the LED power source 4.6 is turned off (step 5). ), the process returns to step 1 and a checkered pattern signal from the primary photosensor 12 is expected.

From then on, following this flow, each time a checkered stripe engraved in the direction perpendicular to the main scanning direction A is detected, the LED 4.6 is turned on, image information and position information are recorded on the image sensors 8 and 8', and the image The data is stored at predetermined addresses on the sleds 10° and 10', respectively. Note that the memory 10,
Image information and position information can be easily outputted from memory output 27 and 28 from memory output 27 and 28 by specifying predetermined addresses respectively using the read state of the R/W signal described above.

For display, a dot matrix liquid crystal display device 30 (fourth
Figure) is used. This consists of a liquid crystal display panel composed of a dot matrix and display data R, which corresponds to each dot.
This device is composed of an AM 30', a driver, and a control device, and dynamically drives each dot according to the contents of the display data RAM 3Q'. Therefore, it is sufficient to transfer the dot pattern to be displayed to the display data RAM.

Here, if the dot matrix liquid crystal display board displays the history of the document currently being scanned, from the current line to the previous line, the purpose of the present invention, which is to prevent recording omissions and double recording, is achieved. be done. Therefore, image senna C
