Description
本發明涉及一種輸入技術，尤其涉及一種紅外線手寫筆及具有該紅外線手寫筆的手寫輸入裝置。 The invention relates to an input technology, in particular to an infrared stylus and a handwriting input device having the infrared stylus.
目前的紅外線手寫筆係在其筆尖上設置有紅外線光源。惟，在使用過程中，這樣的結構容易導致紅外線光源被使用者的手遮擋，造成手寫輸入裝置中的紅外線感測器識別不到該紅外線光源發出的紅外線，從而容易造成輸入受阻。 The current infrared stylus is provided with an infrared light source on its tip. However, during use, such a structure easily causes the infrared light source to be blocked by the user's hand, and the infrared sensor in the handwriting input device does not recognize the infrared light emitted by the infrared light source, thereby easily causing the input to be blocked.
有鑒於此，有必要提供一種不容易被使用者的手遮擋的紅外線手寫筆及具有該紅外線手寫筆的手寫輸入裝置。 In view of the above, it is necessary to provide an infrared stylus that is not easily blocked by the user's hand and a handwriting input device having the infrared stylus.
一種紅外線手寫筆，其包括一筆桿、一筆尖、一連桿及一第一紅外線光源。該連桿具有一連接端和一與該連接端相對的自由端。該第一紅外線光源設置在該自由端。該連桿藉由該連接端可轉動地設置在該筆桿靠近該筆尖的一端。 An infrared stylus includes a pen, a tip, a link and a first infrared source. The link has a connecting end and a free end opposite the connecting end. The first infrared light source is disposed at the free end. The connecting rod is rotatably disposed at an end of the pen near the pen tip by the connecting end.
一種手寫輸入裝置，其包括一寫字板、一紅外線感測器及一上述紅外線手寫筆。該紅外線感測器設置於寫字板上。該紅外線感測器用於接收該第一紅外線光源發射的紅外線。 A handwriting input device includes a tablet, an infrared sensor and an infrared stylus. The infrared sensor is disposed on the tablet. The infrared sensor is configured to receive infrared rays emitted by the first infrared light source.
與先前技術相比，上述紅外線手寫筆及具有該紅外線手寫筆的手寫輸入裝置，因為在連桿的自由端設置有第一紅外線光源，該連桿藉由該連接端可轉動地設置在該筆桿靠近該筆尖的一端，在使用過程中該連桿可相對於筆桿打開，使該第一紅外線光源不容易被使用者的手所遮擋，從而使該手寫輸入裝置容易接收該第一紅外線光源發出的紅外線。 Compared with the prior art, the infrared stylus and the handwriting input device having the infrared stylus have a first infrared light source disposed at a free end of the link, and the link is rotatably disposed on the pen by the connecting end Close to the end of the pen tip, the link can be opened relative to the pen during use, so that the first infrared light source is not easily blocked by the user's hand, thereby making the handwriting input device easily receive the first infrared light source. infrared.

為了對本發明的紅外線手寫筆及具有該紅外線手寫筆的手寫輸入裝置做進一步的說明，舉以下實施方式並配合附圖進行詳細說明。 In order to further explain the infrared stylus pen and the handwriting input device having the infrared stylus pen, the following embodiments will be described in detail with reference to the accompanying drawings.
請參閱圖1，本發明實施方式提供的手寫輸入裝置10包括一寫字板11、一支撐桿12、一紅外線感測器13及一紅外線手寫筆14。 Referring to FIG. 1 , a handwriting input device 10 according to an embodiment of the present invention includes a tablet 11 , a support bar 12 , an infrared sensor 13 , and an infrared stylus 14 .
該寫字板11材質不受限制，該寫字板11係用於定位該紅外線手寫筆14的書寫範圍。 The material of the tablet 11 is not limited, and the tablet 11 is used for positioning the writing range of the infrared stylus 14.
該支撐桿12的一端活動設置於該寫字板11，該支撐桿12的另一端設置有該紅外線感測器13，從而使該紅外線感測器13設置於寫字板11的上方，該寫字板11相對於該支撐桿12可以轉動，如此，可以使寫字板11在位於該紅外線感測器13可以感測的範圍內。其中，該支撐桿12活動設置於該寫字板11的方式可以為多種，本實施 方式中，在支撐桿12與該寫字板11連接的一端設置一凸柱120，該寫字板11上開設一與該凸柱120配合的容置孔110，該凸柱120設置於該容置孔110內使該支撐桿12轉動設置於該寫字板11上。 One end of the support rod 12 is movably disposed on the tablet 11 , and the infrared sensor 13 is disposed at the other end of the support rod 12 , so that the infrared sensor 13 is disposed above the tablet 11 . The word board 11 is rotatable relative to the support bar 12 such that the tablet 11 can be placed within a range that the infrared sensor 13 can sense. The manner in which the support bar 12 is movably disposed on the tablet 11 can be various. In the manner, a protrusion 120 is disposed at one end of the supporting rod 12 and the writing board 11. The receiving board 110 defines a receiving hole 110 corresponding to the protrusion 120. The protrusion 120 is disposed in the receiving hole 120. The support rod 12 is rotatably disposed on the writing board 11 in the hole 110.
該紅外線手寫筆14包括一筆桿141、一筆尖142、一連桿143、一轉軸144及一第一紅外線光源145。 The infrared stylus 14 includes a pen 141, a tip 142, a link 143, a shaft 144, and a first infrared source 145.
請一併參閱圖2，在該筆桿141靠近筆尖142的一端沿該筆桿141的軸向開設一條形槽141a，在不使用時可將該連桿143收容於該條形槽141a內。 Referring to FIG. 2 together, a slot 141a is formed in an axial direction of the sheath 141 at an end of the barrel 141 near the tip 142. The link 143 can be received in the strip groove 141a when not in use.
該連桿143具有一連接端143a和一與該連接端143a相對的自由端143b，該第一紅外線光源145設置於該自由端143b，該紅外線感測器13用於接收該第一紅外線光源145發射的紅外線，如此設置，不妨礙該紅外線感測器13對該第一紅外線光源145的感測。本實施方式中，該第一紅外線光源145為紅外線發光二極體。 The connecting rod 143 has a connecting end 143a and a free end 143b opposite to the connecting end 143a. The first infrared light source 145 is disposed at the free end 143b, and the infrared sensor 13 is configured to receive the first infrared light source 145. The emitted infrared rays are arranged so as not to hinder the infrared sensor 13 from sensing the first infrared light source 145. In the present embodiment, the first infrared light source 145 is an infrared light emitting diode.
優選地，該連桿143的長度為該筆桿141的六分之一左右，因為該連桿143的長度過長則該紅外線感測器13不容易準確感測出該第一紅外線光源145的移動軌跡。本實施方式中，該連桿143的長度為該筆桿141的六分之一，如此，該紅外線感測器13更容易準確感測出該第一紅外線光源145的移動軌跡。 Preferably, the length of the connecting rod 143 is about one sixth of the length of the pen 141. Because the length of the connecting rod 143 is too long, the infrared sensor 13 does not easily accurately sense the movement of the first infrared light source 145. Track. In the present embodiment, the length of the link 143 is one-sixth of the length of the pen 141. Thus, the infrared sensor 13 can more accurately sense the movement trajectory of the first infrared light source 145.
請一併參閱圖3，該連桿143藉由該連接端143a可轉動地設置在該筆桿141靠近該筆尖142的一端。具體地，該連接端143a開設一通孔143c，該轉軸144穿設於該通孔143c內並架設於該條形槽141a靠近該筆尖142的一端。該條形槽141a具有兩個沿該筆桿141軸向延伸的側壁141b，該連接端143a與該兩個側壁141b緊密配合，如 此，在調整該連桿143的位置後，利用該兩個側壁141b與該連桿143之間的摩擦力使該連桿143固定。其中，該連桿143可相對於該筆桿141在0°~135°之間自由旋轉。優選地，在使用時該連桿143與該筆桿141之間的夾角為120°。其中，該夾角也可以根據使用者的需求自行調節。 Referring to FIG. 3 together, the connecting rod 143 is rotatably disposed at an end of the pen 141 near the pen tip 142 by the connecting end 143a. Specifically, the connecting end 143a defines a through hole 143c. The rotating shaft 144 is disposed in the through hole 143c and is disposed at an end of the strip groove 141a adjacent to the pen tip 142. The strip groove 141a has two side walls 141b extending axially along the sheath 141, and the connecting end 143a is closely matched with the two side walls 141b, such as Thus, after the position of the link 143 is adjusted, the link 143 is fixed by the frictional force between the two side walls 141b and the link 143. The link 143 is free to rotate between 0° and 135° with respect to the pen holder 141. Preferably, the angle between the link 143 and the sheath 141 is 120° in use. Among them, the angle can also be adjusted according to the needs of the user.
該手寫輸入裝置10藉由接收該第一紅外線光源145發出的信號，該紅外線感測器13感測該紅外線手寫筆14的移動軌跡，再將識別出該移動軌跡輸入一顯示裝置便可以顯示出來。 The handwriting input device 10 receives the signal from the first infrared light source 145, and the infrared sensor 13 senses the movement track of the infrared stylus 14 and then displays the movement track into a display device to display it. .
上述紅外線手寫筆及具有該紅外線手寫筆的手寫輸入裝置，因為在連桿的自由端設置有第一紅外線光源，該連桿藉由該連接端可轉動地設置在該筆桿靠近該筆尖的一端，在使用過程中該連桿可相對於筆桿打開，使該第一紅外線光源不容易被使用者的手所遮擋，從而使該手寫輸入裝置容易接收該第一紅外線光源發出的紅外線。 The infrared stylus and the handwriting input device having the infrared stylus are provided with a first infrared light source at a free end of the link, and the link is rotatably disposed at an end of the pen near the pen tip by the connecting end, The connecting rod can be opened relative to the pen during use, so that the first infrared light source is not easily blocked by the user's hand, thereby making the handwriting input device easily receive infrared rays emitted by the first infrared light source.
