Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic reading pen device useful for human activities of reading, memorizing, thinking, and writing print.

Students, intellectual workers, and the general public spend a considerable amount of time in their lives reading, memorizing, thinking, and writing. However, it is very rare to transcribe all the printed words that you see, and there is no need to do so, but the transmission of information between people or themselves at intervals is the basis of human intellectual activity. Japanese (language)
Therefore, writing characters, symbols, and figures that can be printed is one of the basic intellectual activities of humans. In this way, the process of reading, memorizing, thinking, and writing is fundamental, and despite the limited condition of Japanese language (language), the process from reading to writing is essential. , Human beings - If you consider the time axis, the same situation will never be repeated even for the person himself.

Electronic devices that can transfer printed text9 figures at high speed are highly developed, but when using printed text at an individual level,
There is no need to transcribe all of them. In other words, there is a need to reuse and record parts of the printed text as a reference or as part of the reader's own thoughts within the framework of the Japanese language, regardless of the need. There are many machines that meet these demands. Therefore, in order to record the use of a part of the printed text, it was necessary to transfer it by hand or copy the page, cut it out, and paste it in a predetermined position with glue. Although such work is one of the most time-consuming tasks in ordinary office work, it is rarely mechanized due to the diversity of its demands. Even now, with the development of computer systems, it is extremely costly and time consuming to recombine the data output and transmitted by computer systems to meet various requirements. When it is necessary to completely rearrange and rearrange a page of notebooks created by a computer, if all you have to do is rearrange the rows and columns, you can simply copy, cut, and abbreviate them. If you want to randomly select and rearrange the top page's worth of data and materials, it will take a lot more time and effort. Therefore, it is usually necessary to rewrite everything by hand9, which is very costly and time consuming.
It is a job that requires

The electronic reading pen 1 has a notch 28 that allows the guide ruler 30 to be placed on the paper! ! It is cut out to the same thickness as the guide ruler so that it can be moved while touching it.

As shown in FIG. 2, the guide ruler 30 has black and white pattern scales 31 of 5096 at regular intervals formed at right angles to the linear end 321C of the guide ruler.
When the ruler is placed on this ruler and moved along the character information to be read on the paper, the distance pattern reading unit 6 reads the black and white pattern 31 of the guide ruler 30 and moves the reading pen 1 depending on whether there is a reflection from the ruler or not. Generates a pulse depending on the distance.

It is desirable that the diameter of the distance light optical fiber between the end of the optical fiber and the plane of the paper is smaller than the diameter of the distance light optical fiber.When the distance pattern reading unit 6 is manually moved over the distance pattern scale 31 of the guide ruler 30 in a direction perpendicular to the scale, the phototransistor The output changes analogously. At a certain level, this is converted into an ON-OFF digital pulse through a trigger circuit. Black and white pattern reading accuracy F when using inexpensive elements
The limit is about 5 i11111 portraits. In the present invention, a 0.25-diameter plastic fiber is used, and the nine-distance pulse is multiplied by two.

! (4,8■) or less in height. In the case of handwriting, the line spacing in a notebook type is 7 to 8 cm. In the case of OIK characters, the line must be as thin as 24 bits or 32 bits. When cutting out 4-height type with a resolution of 32 bits, if you enlarge it twice by 0.125w/bit, then 0.125w/bit will be enlarged.
It becomes 25■. It depends on whether an 8-bit or 16-bit CPU is used as the CPU of the personal computer that is combined with this electronic data transfer device, but in the embodiment of the present invention, if an 8-bit CPU is used, - 0.2 on a straight line

The end face is optically polished and fixed to the holder mechanism, and the other end is optically polished and then A of 8 pieces are sequentially applied starting from the upper edge of the typeface.
They are divided into group B and group B-m-. Currently available small L-element phototransistors with lenses have a width of IC pitch (2

Next, the case where the black and white pattern scale 31 on the guide ruler 30 is read by the distance pattern reading section 6 will be described. The distance pattern reading section 6 has the same basic function as a barcode reader. However, at present, the readable value of a single reading element is eta of about 0.2 ms+, and it is expensive. In the present invention, when using a 0.25-inch optical fiber and drawing two black lines with a leg width of 0.25 m,
The limit is to issue two distance pulses per one. Therefore, the number of distance pulses is doubled.

FIG. 6 is a distance pulse doubling circuit according to the present invention. 41tiLED, 42 is a black and white pattern on a guide ruler, with two 0°25-width black lights of 1s+l. The light from the LED 41 is reflected on the ruler, captured by the optical fiber 43, and photoelectrically converted by the phototransistor 44. The signal from the output section 46 amplified by the linear amplifier 45 is as shown in (1) in Figure 7. If the electronic reading pen 1 is moved at a constant speed with respect to the guide ruler 30, the image shown in FIG.

The lenses are arranged in close contact with the 6Fi row, and the mirror-finished end faces are placed at the actual distance of the lens. The four sets of eight phototransistors are placed at arbitrary positions, and the other end 67 of the optical 7-eyeper 65 is identified as facing the phototransistor 66.

The anode of the phototransistor 66 is the electronic switch 6
3 to the power supply voltage Vυ, and the emitter is connected to a comparator amplifier 60 including a trigger and a trigger. One set of 8 optical fibers 66, A, B, C, D
We consider that there are four sets, and each set is numbered O, 1, ---7 from the top. The 02 ins of each set are collected in an electronic changeover switch 61. The outputs of the eight electronic switches 61 are connected to a pass line connector 62 connected to an 8-bit personal computer. A control signal from the personal computer side is applied to the electronic changeover switch 61 via the connector 68.

FIG. 9 is a diagram of pulses controlling the 32-bit information reading section 20 of the present invention. FIG. 9(1) is a trigger pulse generated by the Fi distance pattern reading unit 6 at every fixed movement distance shown in FIG. 7(d), and is sent to the personal computer via the connector 69. Further, the pulse applied to the reading LED 20 (FIG. 9(b)) is turned on for a certain period of time W. The trigger pulse (1) is sent to the personal computer side (not shown) via the connector 69, and the trigger pulse (1) is sent to the LE via the connector 70.
The pulse for controlling the D-light emission time may be returned as shown in FIG. 8(b). The four consecutive pulses at regular intervals shown in FIG. 8(C) are started by the trigger pulse shown in FIG. 9(a)K, synchronized with the memory write cycle of the personal computer, and the electronic selector switch 61 is set to 0. By switching in the order of ①, ②, ②, the character pattern on the l line read by the optical fiber 65 is divided into 4 sets of 8 lines (1 byte) and read with a slight time difference. The information pattern reading time of a group of optical fibers is shown in Fig. 9(d) to (
The information pattern read at the - timing is placed on the pass line of the personal computer. When the electronic cutting pen is manually moved and moves 200 cm in 1 second, 4 trigger pulses are generated every 1 cm, so the trigger pulse interval is 1250 μs on average. The computer glue frequency is
Even if the computer is operated in steps of several seconds at about 0.5 μ8, the execution time of 4 consecutive pulses (Fig. 8 (C)) is 200 μ.
Can be made below 8. l The amount of movement per trigger pulse is 0.2
5■ (average). The reading time difference between the upper 8 bits and the lower bits of the optical fiber can be set to 50 μ8, so there is no problem in terms of usage. However, the response time of the phototransistor is lO
It is desirable that it be less than μs, and if necessary, it is necessary to use a photodiode as the photoelectric conversion element 26 (66).

A circuit including a latch and a buffer may be placed before or after the electronic changeover switch 61.

The electronic reading Ben device of the present invention has an I10 controller 82.
By connecting to an 8-bit PC via a 55% cable, printed or handwritten character information can be stored in the PC's memory. The paper width of an A4 version is approximately 21 C1l, and when reading 200 ■-lines four times in one line, using a group of 32-bit optical fibers, it takes a memory capacity of 3.2 bytes to read one line in one line. and K.

In current industrial activities, a large amount of negative paper is consumed as a text information medium to be read by humans, and accordingly, a large amount of printed handwritten information is transcribed in offices. In addition, due to its complexity, information that should not be transferred is simply cluttered, piled up as documents, and wasted without being fully utilized.

According to the present invention, the circuits shown in FIGS. 6 and 8 described above are 4X
It is stored in a case of about 5 x 20 cys and can be used with a guide ruler to easily read only the necessary parts with sufficient resolution of printed or handwritten text information, and to read only the necessary parts, such as signal cables and power lines of 16 bits or less. By connecting it to a personal computer, it can be stored in the computer's memory and reproduced as printed text on a printer if necessary, making it a great contribution to personal automation in the office.
