5 is a view illustrating an operation principle of the electronic pen 120 among the electronic dictionary search apparatus 100 of the portable electronic device 130 connected with a pen and Bluetooth capable of scanning a long inclination angle according to an embodiment of the present invention. It is a schematic cross section.

As illustrated in FIG. 5, the pen core 112 may protrude through one end of the general pen case 111, and the electronic pen case 121 may be installed integrally with the general pen case 111. In particular, the general pen case 111 is formed with a sharp pointed end, while the electronic pen case 121 has a rounded portion 126a formed at an end thereof to have a substantially recessed shape. In addition, a through hole 126b is formed in the round part 126a. A light source part 123c is formed outside the through hole 126b, and a reflector 125 and a light source part are formed inside the through hole 126b. 123c and the OCR portion 123d may be formed.

Here, the optical axis by the light source unit 123c is formed substantially parallel to the axis of the pen nib 112, whereby the optical axis by the light source unit 123c is formed along the axis of the pen nib 112 by the user, thereby allowing the user to The character scan area or scan direction can be accurately recognized / adjusted.

On the other hand, the longitudinal direction or the installation direction of the reflector 125 of the electronic pen 120 is installed to have an angle of approximately -30 ° to + 30 ° with respect to the longitudinal direction or the placed direction of the document. Preferably, the longitudinal direction of the reflector 125 of the electronic pen 120 is at an angle substantially parallel to the longitudinal direction of the document.

In one example, the electronic pen 120 forms an inclined angle of approximately 1 ° to 89 ° with respect to the longitudinal direction of the document. The electronic pen 120 is tilted due to the installation angle of the reflector 125 described above. Despite the photographic angle (approximately 45 ° to 89 °), the characters in the document can be easily recognized by the electronic pen 120.

In addition, the light source 123c may be installed so that the optical axis of the light source 123c coincides with the normal direction of the reflector 125, and the OCR 123d may be installed substantially parallel to the axis of the pen nib 112. .

Here, the angle of the light incident on the reflector 125 from the document may be the same as the angle of the light incident on the OCR portion 123d. Of course, since the character is inverted once from the document by the reflector 125, the OCR unit 123d inverts the incident character once again, so that the user or program can recognize the character.

6A to 6C illustrate an operation process of the electronic pen 120 of the electronic dictionary retrieval apparatus 100 of the portable electronic device 130 connected by Bluetooth with a pen capable of scanning a long inclination angle according to an embodiment of the present invention. It is a schematic cross section for explanation.

As shown in FIG. 6A, when the electronic pen 120 is normally used as the general pen 110, the pen core 112 protrudes outward through a hole formed at one end of the general pen case 111. Do That is, the spring 113 coupled to the pen nib 112 is in close contact with the fixing member 114, and the other side of the spring 113 pushes the protrusion 112a of the pen nib 112 outward, so that the pen nib 112 ) Is protruded from the general pen case 111 is in a state capable of writing. At this time, the protrusion 112b formed in the nib 112 is not yet coupled to the hole 114a formed in the fixing member 114. In addition, at this time, the other end of the pen nib 112 does not pressurize the switch unit 123a, thereby keeping the electronic pen 120 turned off.

Further, at this time, the protrusion 112b formed in the pen core 112 is coupled to the hole 114a formed in the fixing member 114, so that the pen core 112 is returned to its original position despite the elastic force or the restoring force of the spring 113. It does not return. In this manner, when the nib 112 presses the switch unit 123a, the switch unit 123a is turned on, and thus the electronic pen 120 is turned on. That is, when the switch unit 123a is turned on, the light guide unit 123b, the light source unit 123c, the OCR unit 123d, the communication unit 123e, the storage unit 123f, and the control unit 124 of the electronic pen 120 are turned on. The power of the power source 123g is supplied to and turned on.

In this state, when the user moves the electronic pen 120 in the document by the guide of the light guide unit 123b in the predetermined direction, the character of the document is scanned in the moving direction, and the scanned character is reflected through the reflector 125. Characters in the document are recognized by being input to the OCR unit 123d.

Of course, the recognized text is transmitted to the external electronic device 130 in real time through the communication unit 123e, and then the electronic device 130 searches for the text through the electronic dictionary application installed therein and outputs the result of the output module ( 131b) or the electronic device 130 transmits the text to the server 140, the server 140 retrieves the text through the electronic dictionary program installed in the server 140 and transmits the result to the electronic device 130. The electronic device 130 displays this to the user through the output module 131b.

Subsequently, as shown in FIG. 6C, when the user presses the nib 112 of the general pen 110 again, the protrusions formed in the nib 112 from the holes 114a formed in the fixing member 114. As the 112b is separated, the pen nib 112 protrudes again through the opening of the general pen case 111 by the elastic force / restoring force of the spring 113, thereby releasing the pressure applied to the switch unit 123a. Therefore, the switch unit 123a is turned off, and thus the operation of the electronic pen 120 is stopped. That is, the power applied to the light guide part 123b, the light source part 123c, the OCR part 123d, the communication part 123e, the storage part 123f, and the control part 124 is cut off from the power supply part 123g.
