Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an image recording device, and particularly to an image recording device that displays input signals of characters from the outside in addition to read image signals on a built-in display section and records them in a memory. This invention relates to a portable image recording device.

[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, it can be easily inferred that a hand-held image recording device can be created by incorporating the senna into a portable casing.

However, conventional devices of this type and handheld image recording devices only optically read the image of a document and convert the image information into electrical signals, so they cannot accept other external input signals. They did not have the means to accept them.

In addition, since it does not have a display section that displays this information while recording image information, there is no way to input simple notes etc. on the display section, making it inconvenient and time-consuming to edit and organize images. There was a drawback.

〔the purpose〕

The present invention was made in view of the above-mentioned problems, and includes a display unit built into a portable image recording device.
This is an attempt to solve the above-mentioned runner-up problem by inputting a simple memo or the like and recording it in the memory.

〔Example〕

The present invention will be explained below based on 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 position information, 3 is a document to be recorded, AFi, the movement (main scanning) direction of this device, D is a swingable liquid crystal display, and E is an external Indicates an input terminal.

The transparent sheet 2 has checkered stripes etched on its surface by chemical treatment perpendicular to the main scanning direction A, with a line width of 50 μm and 8 lines/sn.
They are carved at equal intervals. 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 an enlarged local surface view of the transparent sheet 20. 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, if the initial interval is aam and 1 pixel I IIm, then a, a+1, a+2, . -a
The lattice stripes are carved at intervals of +nti+. 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, 4.6.13flLBD light source, 5s5
's! lr' is a lens, 8 and 8' are image sensors (OOD) for reading image information, and 9 [its control device, 10t/
i storage memory, IIFi power battery, +2 is a photosensor. The light from the LED light source 4 passes through the transparent sheet 2
Even when the light is irradiated onto the checkered stripes, it is incident at an angle (r160° or more in this embodiment) that allows the light to pass through and is irradiated onto the document 3, and the reflected light is recorded on the image sensor 8 as image information through the lens 5.

On the other hand, the light from the LED light source 6 is reflected by the checkered stripes of the transparent sheet 2 (in this embodiment, the light is incident at an angle of 30 degrees) 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 of the checkered stripes in the B direction by the image sensor 8' recording the reflected light from the LBD 6. Recording in the main scanning direction A is L
The ED light source 13 detects the reflected light from the 8 lines/lIm checkered stripes carved perpendicular to the six directions by the photosensor 12 through the lens 5'', and the image sensor 8°3-8'10 control device 9 and operate these image sensors 8, 8' at every grid interval,
Printing is performed in the main scanning direction A.

For example, each image sensor 8.8' has n pixels, and each pixel corresponds to an image plane of about 1/8I1m, and by adopting a configuration with a resolution of 8pe+, six By activating the image sensors 8 and 8' each time the photosensor 12 detects 8 lines/lS+ checkered stripes carved in the direction perpendicular to the direction, data for one line of n pixels is recorded. It can be done reliably. Note that each of the above-mentioned LEDs, image sensor, photosensor, control section, and memory is driven by one battery.

Image information read by the image sensors 8, 8' in the manner described above is recorded in the memory 10. Although it may happen that one piece of image information is recorded twice or more in the memory 10 by arbitrary scanning, each piece of image information is recorded in a state that corresponds to the position information.

4- Furthermore, the image information detected by the movement of the reading section is recorded in the memory 10 and is also sent to the liquid crystal display section, so that the recorded portion is displayed on the liquid crystal display at the same time as recording. When it is desired to input a date, a simple memo, etc. to the image displayed on the liquid crystal display section, it is possible to connect a simple keyboard or the like to the external input terminal E as an example of an option.

Further, on the surface of the swingable liquid crystal display section shown in FIG. 1, a mask on which handwriting can be written is superimposed. On this mask, rtMXN electrodes are arranged in the vertical and horizontal directions, and by tracing the mask with the tip of a pencil, a voltage change is generated, and this change is read. In this way, it was possible to also store the image drawn on the mask in memory.

FIG. 4 shows the control device 9 of the embodiment (FIG. 2) of the present invention.
A block diagram showing the circuit configuration of is shown. This control device is
It is composed mainly of a well-known one-chip microcomputer 0PTJ21 with built-in ROM and RAM, and is sequentially controlled by a program stored in the 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 13 is turned on. is turned on, and the reflected light from the above-mentioned checkered stripes is detected by the sensor 12 and input to the input boat 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, to obtain image information and location information,
Output capo to turn on LED light source 4.6) Fl,
F2 is turned on, a main scanning counter (described later) is reset, and gate 2 is turned on to start storing data from the image sensors 8 and 8' in the memory 10 and 10'.
Turn on 0.〈Turn on output port F3 and proceed to the next step. When the aforementioned LED light sources 4 and 6 are turned on, the image sensors 8 and 8' are irradiated with reflected light, and image information and position information are sent to each pixel as an analog signal. Accumulated.

On the other hand, by turning on the gate 20, the reference oscillator (080
) 21 is connected to the image sensors 8, 8', and the analog signals of each pixel are sequentially read out as serial data. This analog signal is transmitted to A/D conversion circuits 22 and 23.
After being converted into a digital value of predetermined bits and further binarized by a predetermined image signal processing circuit 24.25, it is inputted to the memory 10.10' as video data.

FIG. 6 shows the image/position recording information signal. Also, by turning on the gate 20, the reference oscillator (080) is activated.
The output of 08021 is input to the input port P1 2. In step 3, the detection of the clock from this 08021 is continued to be monitored, synchronization is achieved with the clock present, and the aforementioned video data is stored in the memory 10 *'I O'. Outputs address data ADR3 that determines the address to be stored to port F4
Also, the W/R signal which is the write signal of Memo 7-Ril O, IO' is output from W.
By outputting the video data from the output port F5 as RI TFli, the video data described above is stored in the memory space at a predetermined address. Next, in step 4, the address data is incremented, the address of the video data for the next pixel is determined, and the address data of the image sensor 00D8 is determined.
．． The main scanning counter corresponding to n pixels of 8' is incremented and monitoring is continued until the counter discharges data of all n pixels. If the counter does not end, the process returns to step 3, waits for the next clock, synchronizes, and repeats the operation of storing the video data for the next pixel in the memory. In this way, when the counter ends, recording of image information and position information for 1247 minutes in the main scanning direction A of the image sensor OOD is completed, and the gate 20 is turned off and the LED power sources 4 and 6 are turned off (step 5),
Returning to step 1 again, checkered signals from the next seven sensors 12 are expected.

From then on, following this flow, each time a checkered stripe carved in a direction perpendicular to the main scanning direction A is detected, the LED 4.6
is turned on, image information and position information are recorded in the image sensors 8 and 8', and are further stored in the memories 10 and 10' at predetermined addresses. To read the image information and position information, set the R/W signal □ mentioned above to the Read state and specify the respective predetermined addresses to read the memory output 27.
．． It is easily performed from 28 onwards.

The external input device may have a configuration as shown in the block diagram of FIG. 7, for example. FIG. 8 is a flowchart of a control program for this external input device. In FIG. 7, 29 is an OPU, 30 is a keyboard for input data, 31U is a ROM that stores a program and a dot pattern table containing characters for creating dot patterns, and 32 is a RAM that holds dot patterns.

The operation of the external input device will be explained below according to the flowchart of FIG. Here, as a simple character manual device,
The size of the characters is limited to, for example, m x m bits. First, the switch 33 connected to the port P6 of 0PTJ29 is scanned, and if the switch is on, a bit counter to be described later is reset and the process returns to the beginning (step 1). Next, the switch 34 connected to the OPP2O3 boat P1' is scanned, and if it is on, a transmission counter, which will be described later, is reset and the keyboard 30 is scanned. If no key is pressed at this time, return to the beginning. If the key has been pressed, the character->bit-up table in the ROM 31 is referred to, the data is divided into dot patterns, stored in the RAM 32, and the bit counter is incremented by mXm. Then, return to the beginning (step 2).

This operation is repeated until the switch 34 is turned off, and i
The character dot pattern is stored in the RAM 32. Also,
When the switch 33 is turned on, characters can be input again from the beginning.

Next, the boat Pt is scanned. Boat P'2c is connected to boat F6 of 0PfJ26 (FIG. 4) of the portable image recording device 9. When this boat F6 is turned on, 0PU of character data made into a dot pattern
29 (FIG. 7), transmission to the 0PU 26 is started.

First, the contents of the transmission counter (() are compared with the contents of the aforementioned bit counter, and if there is no character data, turn on port F'1 and return to the beginning. If there is character data, send it to F'o) and increments the send counter. Next, the port p/ is scanned and continues scanning until it is turned on, and when it is turned on, the process returns to (a) above (step 3).

The operation of the portable image recording device 9 corresponding to the operation of the above-mentioned simple character input device will be explained with reference to the flowchart of FIG. 5 mentioned above.

From the keyboard of the simple character input device, follow the steps above to enter RA.
Assuming that a character dot pattern is recorded in M32 (FIG. 7), switch 85 (FIG. 4) is set to communication mode with the simple character input keyboard in step 11.
), 0Pff26 baud)F, the following processing is started.

First, enter the position where the text should be placed. As a method of specifying the 11-position, for example, place a button/bottle in each of the X direction and Y direction on the surface of the liquid crystal display panel shown in FIG.
This can be achieved by providing cursors 36 and 37 connected to the shimimeters, expressing the coordinates at the intersection of the two movement positions, and inputting the value in the X direction to the boat P6 and the value in the Y direction to the boat P. can.

Based on the X-Y coordinates on the liquid crystal display board obtained above and the address output from the address port F4, which has stopped due to the previous image information import operation, enter the address of the memory where the character pattern should be input. By calculation, boat F

Next, turn on the boat Fs (i.e. P'2),
The simple character input device is designated to perform output, and the boat P4 (ie, F'1) is monitored.

When P4(r-/1) is turned on, (
(b) Turn off F6 (P', ), scan the boat P4, and if it is off, perform image processing and return to the original state (step 13). Set the boat Fls to the memory RFiAD state 12- and read data from the memory. Also, read the output of the simple character input device from boat P3 (F'o), OR it with the above memory data, and set boat F5 to WRI.
Set to TE state and write from boat F8 (step 14)
).

Next, put boat F in the READ state, calculate the address to which the next dot data should be written, and write it to boat F4.
Output from . After that, turn on the boat F6 and return to the above (b) (step 15). This is repeated until boat P4 is turned off.

Through the above operations, characters inputted from the simple character input device can be inputted by "superimposing" the characters inputted from the cursor position on the liquid crystal display board on the image inputted using the portable image recording device. became possible.

In addition, a transparent coordinate input device that allows you to specify coordinate information with your finger or the tip of a lead wire is placed on the liquid crystal display panel, and once the image signal is input to the portable image recording device,
You can input images by hand.

, -14- The method will be explained below. Transparent sheet input devices have been proposed such as a switch matrix method and an optical method, but methods that use transparent resistive sheets and conductive sheets to determine coordinates from the voltage or current division ratio have improved resolution and peripheral circuitry. It is valid from the point.

An example is shown below. FIG. 10 (Al is a diagram of the principle of position detection, 38Fi resistance sheet, 39 is a conductive sheet. A DC voltage is applied to both ends of the resistance sheet 38. On this resistance sheet 38, Conductive sheet 39
are stacked with extremely thin intervals, and the resistance sheet 3
The conductive sheet 39 and the resistive sheet 38 are brought into contact by pressing down on one point on the surface of the conductive sheet 39 and the resistive sheet 38. Therefore, the voltage value of the conductive sheet 39 corresponds to the coordinates.

FIG. 10 (bl) shows an equivalent circuit for the above operation.

In the above example, a DC voltage was applied, but even if an AC signal is used, the conductive surface 39a of the conductive sheet 39 and the insulating surface 39
b can be reversed to utilize the capacitance change caused by pressing, or, contrary to the above example, direct current (
Alternatively, other methods may be used, such as applying an alternating current (AC) signal and determining the coordinate position from the current flowing through the electrodes at both ends of the resistance sheet 38.

FIG. 11 shows the configuration of an actual example. A transparent resistive sheet 38' and a transparent conductive sheet 39 are placed over the liquid crystal display panel.

a, 40b+41a, 41b are provided, a DC or AC signal is alternately applied to each, and the voltage value of the conductive sheet 39' is read. The read value is A/D converted for processing by a microcomputer and taken into the CPH together with a signal identifying whether it is in the X or Y direction. Note that 42 indicates an analog switch, 43 Fi buffer, and 44 a clock.

In the flowchart shown in FIG. 5, if the switch 35 is in the handwriting input mode, the following processing is performed. That is, first, the X and Y coordinates are read.

If there is no coordinate signal, no further processing is performed and the process returns to the beginning. If there is a coordinate signal, the memory address corresponding to the coordinates of the pressed point can be determined from the final address of the memory where the X-Y coordinates and image information signal are input, and the address (
By entering 11" into F8), you can input image information by hand into the memory (Step 2).
