Description

Electromagnetic pen with multi-function tail

The invention provides a multifunctional electromagnetic pen, in particular to an electromagnetic pen with a multifunctional tail end.

The electromagnetic induction type handwriting input device is mainly used with a digital tablet and a dedicated electromagnetic signal pen (referred to as an electromagnetic pen). A conventional electromagnetic pen is provided with a "spiky" tip at the front end for writing or pointing an object on the tablet, and an erase device is disposed at the rear end (ie, the tail end). (ie electromagnetic induction eraser), used to erase text, graphics or marks on the tablet.

However, when painting with this "spike-shaped" nib, although most of the painting methods can be covered, it is impossible to accurately simulate the unique painting effect formed by the oil painting knife. This is because the oil painting knives used in oil paintings come in a variety of sizes and shapes, ranging from sharp pointed shapes to oval-shaped oil painting knives, so that various effects can be drawn. In addition, by using a different knife method such as pressing, dragging, wiping, scraping, etc., using a painting knife to draw, different drawing effects can be achieved, or the oil painting knife can be used to scrape and recolor the unsatisfactory place. These effects and functions are the touches and effects that the electromagnetic pen with a "spiky" tip is not available on the digital tablet on the market today.

In addition, conventional electromagnetic pens mostly have an eraser device at the end, and these have an eraser. The patents of the electromagnetic pens of the wiping device, for example, U.S. Patent Nos. 4,697,050, 5,325,110, 5,401,916, 5,576,502, and 5,793,360, all of which have some design deficiencies. An electromagnetic pen 10 (shown in the first figure) having a pencil lead 12 at one end and an eraser 14 at one end is disclosed, for example, in US Pat. No. 4,697,050, which controls the oscillating circuit 18 to emit a specific by the user pressing the switch 16 or 17. The electromagnetic signal of the frequency, so that the tablet recognizes whether the electromagnetic pen is in the writing mode or the erasing mode. However, the disadvantage is that a spring structure 19 is required to cause the eraser 14 to rebound, which not only increases the complexity of its structure, but also increases the cost and difficulty of its manufacture. Another disadvantage of the electromagnetic pen 10 is that the eraser 14 needs to be in contact with the tablet to retreat the switch 15 by force, thereby turning on the erase mode, so the eraser 14 and the tablet need to be erased. Constant contact causes the two to constantly rub, so that the eraser 14 made of plastic or rubber will continue to wear, and needs to be replaced frequently, resulting in an increase in the burden on the user and a decrease in ease of use.

The electromagnetic pen disclosed in U.S. Patent No. 5,576,502 is a cylindrical electromagnetic pen 20 (shown in the second figure) having a coil 22 at the tail to have the function of an eraser, and the coil 22 has a dome shape. The rear cover 24 is covered and has a resilient structure 26 disposed therefor to spring the rear cover 24 back when the electromagnetic pen 20 leaves the surface of the tablet without being erased. When the electromagnetic pen 20 performs erasing, the rear pen cover 24 is pressed against the surface of the tablet, and the rear pen cover 24 is pressed against the elastic structure 26 to retreat, thereby opening the switch in the pen to turn on the erasing mode. Erasing begins, so it needs to be in constant contact with the tablet during the erasing process. However, such a "push-type" electromagnetic pen, because of the need for an elastic structure, is not only complicated in structure but also high in manufacturing cost, and when it is wiped on the tablet, it needs to be in contact with the tablet, resulting in contact with the tablet. Unpleasant rubbing sounds are generated when erasing, and it is liable to cause scratches on the surface of the tablet and wear of the end of the electromagnetic pen.

U.S. Patent No. 5,793,360 discloses a type of electromagnetic pen that is not selected on the tablet. The same shape of the cursor for wiping text or objects, which mainly uses an application to identify the currently used cursor to determine whether to erase text or objects, but the electromagnetic pen used is the same as the aforementioned US Patent No. 4,697,050 and the United States. The electromagnetic pen disclosed in the patent US 5,576,502 is a "press type" electromagnetic pen, and therefore has the same disadvantages.

As described in the aforementioned patents, most of the tail ends of the electromagnetic pen have only one erasing function, and the tail end of the electromagnetic pen does not have different functions, resulting in a single function and operation mode of the electromagnetic pen. It does not meet the requirements of today's diversification and functionalization of electronic products. In addition, since most of the eraser at the end of the electromagnetic pen has a dome-shaped structure, it is also the same as the "spike-shaped" nib of the electromagnetic pen, and it is not possible to use different painting knives such as pressing, dragging, wiping, scraping, and the like. Use the method to draw, and draw a picture with oil painting features on the tablet.

In view of the above shortcomings, there is a need for an electromagnetic pen which has a simple structure and a low production cost, but can have multiple functions, in particular, it does not need to be provided with an elastic structure at the tail end, and can also have an erasing, amplifying, and a painting knife. A multi-function electromagnetic pen, and when the erase mode is performed, the end of the electromagnetic pen does not need to be in contact with and rubbed against the tablet to prevent noise and damage.

An object of the present invention is to provide an electromagnetic pen having a multi-functional tail end which is simple in structure and low in production cost. The end of the electromagnetic pen can have a plurality of different functions such as erasing, amplifying, and a painting knife, and the operating mode and function of the electromagnetic pen are more flexible and variable, and the electromagnetic pen tail is used in the erasing mode. The end does not need to contact and rub with the tablet, and prevents noise and damage to the electromagnetic pen or tablet due to contact and friction between the end of the electromagnetic pen and the tablet.

According to the above object, the present invention provides an electromagnetic pen having a multi-functional tail end, which is not only simple in structure, low in manufacturing cost, but also has various functions such as erasing, enlarging, and oil painting. This item The electromagnetic pen with the multifunctional tail end is composed of a body, a tip and a multi-function electromagnetic coil ring. The pen body has a front end and a tail end, and the pen tip is disposed at the front end of the pen body for writing or selecting an object on the tablet. The multi-function electromagnetic coil ring is disposed at the end of the pen body to emit different electromagnetic signals, and in different cases, the end of the electromagnetic pen has different functions, such as erasing, amplifying, and painting knife functions. . The tablet determines the function represented by the tail end of the electromagnetic pen according to the frequency of the electromagnetic signal emitted by the multi-function electromagnetic coil ring, and because the multi-function electromagnetic coil ring has a ring structure, it can help the user to clearly Defining the scope of the selected text or object, and further erasing or enlarging the characters or objects in the range, such as patterns, marks, and the like. In addition, since the multi-function electromagnetic coil ring has a similar ring structure as the oil painting knife, so that the two have the same hand feeling in use, the user can use the tail end of the electromagnetic pen as a painting knife, and Use a different knife method such as pressing, dragging, wiping, scraping, etc. to draw on the tablet, and achieve the effect of oil painting on the tablet. Since the multi-function electromagnetic coil ring controls the frequency of the electromagnetic signal and the frequency of the electromagnetic signal by the switch disposed on the surface of the pen body, the multi-function electromagnetic coil ring does not need to be in contact with the tablet to open different functions and modes. So you can perform its functions (or modes) directly on top of the tablet, such as erasing, without touching the tablet.

Therefore, the effect of the present invention over the prior art is to provide an electromagnetic pen which has a simpler structure and a lower production cost, but can have multiple functions, in particular, the tail end can have both erasing, amplifying, and a painting knife. A multi-function electromagnetic pen, and when used in the erase mode, the electromagnetic pen can be used directly above the tablet without contacting the tablet, so there is no noise and damage caused by the friction between the two.

The prior art of the present invention, which is used in the prior art, is only referred to herein by reference.

Referring to the third figure, a schematic diagram of the appearance of the electromagnetic pen 100 having a multi-functional tail end at different angles according to an embodiment of the present invention is shown. The electromagnetic pen 100 having a multi-functional tail includes a pen body 102 having a front end and a rear end, a tip 104 and a multi-function electromagnetic coil ring 106. Wherein, the nib 104 is disposed at the front end of the pen body 102, and by writing an electromagnetic signal to the tablet or reflecting the electromagnetic signal emitted by the tablet to the tablet, the writing of the character and the drawing of the pattern are performed on the tablet. And the selection of objects and other functions. The multi-function coil ring 106 is disposed at the tail end of the pen body 102, and the end of the electromagnetic pen 100 (ie, the multi-function electromagnetic coil ring 106) is in different situations by transmitting electromagnetic signals of different frequencies to the tablet. Has different functions, such as erase, zoom, and oil knife.

The middle portion of the multi-function electromagnetic coil 106 is provided with a transparent sheet 111 made of a transparent material such as glass, film or plastic, and the surface of the sheet 111 is printed or etched with a similar sight for aiming. The glyph pattern 113 is used to assist the user in knowing the sensing center point of the multi-function electromagnetic coil 106. It is of course also possible to print or etch other shapes of the pattern on the sheet 111, such as a circular pattern like the center point on the target, to assist the user in knowing the sensing center point of the multi-function electromagnetic coil 106.

A first switch 108 is disposed on a portion of the pen body 102 near the pen tip 104 for controlling the pen tip 104 to emit electromagnetic signals of different frequencies. A portion of the pen body 102 adjacent to the multi-function electromagnetic coil 106 is provided with a second switch 110 for controlling the multi-function electromagnetic coil 106 to emit electromagnetic signals of different frequencies to control and change the function of the multi-function electromagnetic coil 106. .

Although the electromagnetic pen of the present invention has the appearance and structure as shown in the third figure, it can be distinguished according to its internal structure and design as a battery-type electromagnetic pen with a multifunctional tail end and a battery-free multifunctional tail. The electromagnetic pen of the end is in two forms. Referring to the fourth figure, it is a schematic diagram of the internal structure of a battery-type electromagnetic pen 100A having a multi-functional tail end according to an embodiment of the present invention. The battery-type electromagnetic pen 100A having a multi-functional tail end is also composed of a body 102, a tip 104, and a multi-function solenoid ring 106. A first oscillating circuit 114 is disposed in the front end of the pen body 102 or in the pen tip 104 for transmitting electromagnetic signals to the tablet, so that the pen tip 104 can be written and selected on a digital tablet (object or function point) selected).

The first oscillating circuit 114 includes a first coil 116 wound on the magnetically permeable material 118 for emitting an electromagnetic signal, wherein the first wire coil 116 is wound in a direction parallel to the center line C of the pen body 102 and is wound around Magnetically permeable material 118. The first switch 108 disposed on the portion of the pen body 102 near the pen tip 104 includes two side buttons 1081 and 1082, which respectively correspond to a capacitor (not shown). When the side button 1081 or 1082 is pressed by the user, the corresponding capacitor is connected to the first oscillating circuit 114 to participate in the operation of the first oscillating circuit 114, thereby starting to emit electromagnetic signals or changing the electromagnetic emissions thereof. The frequency of the signal enables the tablet to detect and sense the electromagnetic signal emitted by the pen tip 104 of the electromagnetic pen 100A, and the electromagnetic pen 100A can perform writing, drawing, or object selection on the tablet with the pen tip 104.

In the end of the electromagnetic pen 100A or in the portion of the pen body 102 close to the multi-function electromagnetic coil 106, a second oscillating circuit 120 is disposed for transmitting electromagnetic signals of different frequencies to the tablet, so that the tablet can be The mode and function currently adopted by the multi-function electromagnetic coil 106 are identified, so that the multi-function electromagnetic coil 106 can be erased on the tablet (eraser function), zoomed in (magnifying glass function), and oil painting (painting knife function) ) and other different functions. The second oscillating circuit 120 includes a second coil 122 disposed in the multi-function electromagnetic coil ring 106. The second coil extends in the center line C direction of the vertical pen body 102 and is wound in the multi-function electromagnetic coil ring 106. Therefore, the direction in which the first coil 116 and the second coil 122 are wound and extended is perpendicular to each other.

The second switch 110 disposed on the portion of the pen body 102 that is adjacent to the multi-function electromagnetic coil 106 also includes two side buttons 1101 and 1102, which also respectively correspond to a capacitor (not shown). The side buttons 1101 and 1102 can be pressed by the user or pressed at the same time. Each pressing mode represents an operation mode or function of the multi-function electromagnetic coil ring, for example, the second oscillating circuit 120 starts to emit electromagnetic signals to notify The tablet user starts to use the multi-function electromagnetic coil 106 of the electromagnetic pen 110A to operate thereon, or connects its corresponding capacitor to the second oscillating circuit 120 to change the frequency of the electromagnetic signal emitted by the electromagnetic pen 110A to change the multifunctional electromagnetic The mode and function currently employed by coil ring 106. Wherein, the frequency of each electromagnetic signal emitted by the multi-function electromagnetic coil 106 represents a different function, and the tablet relies on identifying the multi-function electromagnetic coil ring 106. The frequency of the electromagnetic signal identifies the mode and function currently used by the multi-function solenoid ring 106, such as erasing (eraser function), zooming (magnifying glass function), and oil painting (painting knife function). The tablet recognizes the current function (or mode) of the multi-function solenoid ring 106 and performs corresponding actions and changes on the tablet screen.

In addition, a battery 124 is further disposed in the electromagnetic pen 100A for supplying electric energy to the first oscillating circuit 114 and the second oscillating circuit 120 to perform electromagnetic signal transmission. In the embodiment, a circuit board 126 is disposed in the electromagnetic pen 100A, and the capacitors corresponding to the first oscillating circuit 114, the second oscillating circuit 120, the battery 124, and the side buttons 1081, 1082, 1101, and 1102 are uniformly disposed on On board 126. However, in other embodiments of the present invention, two circuit boards may be disposed in the pen body 102, and the capacitors corresponding to the first oscillating circuit 114 and the side buttons 1081 and 1082 are respectively disposed on a circuit board, and The capacitors corresponding to the two oscillating circuits 120 and the side buttons 1101 and 1102 are disposed on another circuit board.

In the electromagnetic pen 100A, the first oscillating circuit 114 and the second oscillating circuit 120 can adopt various oscillating circuits according to their design requirements, such as a Hartley Oscillator, a Colpitts Oscillator, and a Clapp. Circuits such as an oscillating circuit (Clapp Oscillator) or a Wien bridge oscillating circuit (Wien bridge).

Referring to a fifth diagram, it is a schematic diagram of the internal structure of a batteryless electromagnetic pen 100B having a multi-functional tail end according to an embodiment of the present invention. The electromagnetic pen 100B has a similar structure to the electromagnetic pen 100A, and the two are also composed of a body 102, a tip 104, and a multi-function solenoid ring 106. In addition, the two also have a first oscillating circuit 114 and a second oscillating circuit 120 for transmitting and receiving electromagnetic signals, respectively, and both have the first switch 108 and the second switch 110 respectively controlling the nib 102 (or the first oscillating The circuit 114) and the multi-function electromagnetic coil 106 (or the second oscillating circuit 120) emit electromagnetic signals, and control or change the frequency of the electromagnetic signals emitted.

However, the batteryless electromagnetic pen 100B differs from the battery-type electromagnetic pen 100A in that the batteryless electromagnetic pen 100B does not have any battery that can supply electric energy. When the electromagnetic pen 100B performs writing or selecting an object on the tablet with the pen tip 104, the first coil 116 senses the electromagnetic energy emitted by the tablet, and the electromagnetic energy emitted by the first oscillation circuit 114 and the tablet is Resonance, thereby receiving electromagnetic energy and storing, and using this energy as the energy of the first oscillating circuit 114 to emit electromagnetic signals. Similarly, when the electromagnetic pen 100B performs the functions of erasing, enlarging, or oil painting on the digital board by the multi-function electromagnetic coil 106, the second coil 122 senses the electromagnetic energy emitted by the tablet, and makes the second The oscillating circuit 120 resonates with the electromagnetic energy emitted by the tablet to receive the electromagnetic energy and store it, and uses the energy as the energy of the second oscillating circuit 120 to emit the electromagnetic signal.

In the batteryless electromagnetic pen 100B, the first oscillating circuit 114 and the second oscillating circuit 120 are both an LC circuit, which can be directly disposed in the pen body 102 (as shown in FIG. 5), or first set in a On the circuit board, the circuit board is placed in the pen body 102.

In addition, in the electromagnetic pen 100 of the present invention (including the batteryless electromagnetic pen 100B and the battery-type electromagnetic pen 100A), the multi-function electromagnetic coil ring 106 is connected to the tail end of the pen body 102 by a bendable portion 112. The electromagnetic pen of the present invention can be used as a common bendable straw to allow the user to freely adjust the angle, and the angle of the multi-function electromagnetic coil 106 can be freely adjusted to increase the convenience and flexibility of use.

In addition, whether the batteryless electromagnetic pen 100B or the battery-type electromagnetic pen 100A described above, the nib 104 is a "spike-shaped" nib like the nib of the conventional electromagnetic pen, and has a conventional electromagnetic pen. The same operation mode and function as the nib. However, since the electromagnetic pen (including the electromagnetic pen 100, the batteryless electromagnetic pen 100B, and the battery-type electromagnetic pen 100A) of the present invention replaces the dome-shaped eraser of the conventional electromagnetic pen tail with a multi-function electromagnetic coil ring 106. And controlling and changing the function by the second switch 110 The electromagnetic signal frequency emitted by the electromagnetic coil 106 makes the tail end of the electromagnetic pen of the present invention no longer limited to a single wiping function and needs to be in contact with the tablet for a single operation mode, but can have more functions and operations. The mode, which can include at least the following three functions and modes of operation: the first function is the erase function (or the eraser function). When the multi-function electromagnetic coil ring 106 is controlled by the second switch 110 to emit an electromagnetic signal frequency defined by the tablet as an erase mode, the multi-function electromagnetic coil ring 106 is provided as long as the state of the second switch 110 is not changed. The electromagnetic signal defined by the tablet as an erase signal is continuously transmitted. Therefore, the tail end of the electromagnetic pen 100, 100A, 100B of the present invention (or the multi-function electromagnetic coil ring 106) is erased in a manner of being hovered over the tablet, and does not need to be in contact with the tablet at all. The known electromagnetic pen needs to be in direct contact with the tablet in an erasing mode, and does not cause wear or damage to the end of the electromagnetic pen due to contact and friction with the tablet, and does not cause unpleasant noise due to friction.

In addition, since the end of the electromagnetic pen 100, 100A, 100B (or the multi-function electromagnetic coil ring 106) does not need to be in contact with the tablet when erasing, an elastic structure is not required as the erase mode. The control is turned on and off, and the second switch 110 on the side of the pen body 102 is directly controlled and turned on. Therefore, the electromagnetic pens 100, 100A, and 100B are simpler in structure than the conventional electromagnetic pens, and the cost of fabrication and production is reduced. Since the sheet 111 of the multi-function electromagnetic coil ring 106 is a transparent sheet printed on the surface or etched with a cross or a circular pattern, the user can be assisted to know that the center point of the wiping is there. When the end of the electromagnetic pen 100, 100A, 100B (or the multi-function electromagnetic coil 106) emits an electromagnetic signal representing the erasure, the application corresponding to the erase mode in the tablet will be received by the tablet. The data includes the mode ID (X/Y) of the end of the electromagnetic pen and the state of the second switch, and determines the end of the electromagnetic pen 100, 100A, 100B (or the multi-function electromagnetic coil) Ring 106) is in erase mode and erases text, patterns, colors, etc. in the area through which the tablet passes.

The second function is the zoom function (or the magnifying glass function). When the multi-function electromagnetic coil 106 is controlled by the second switch 110 to emit an electromagnetic signal frequency defined by the tablet as the amplification mode, the multi-function solenoid ring 106 continues as long as the state of the second switch 110 is not changed. The ground emission is defined by the tablet as an electromagnetic signal that amplifies the signal. When the digital board receives the amplified signal from the multi-function solenoid coil 106, the application corresponding to the amplification mode (or magnifying glass mode) in the tablet will transmit the mode ID (code ID) and coordinates (X) according to the tablet. /Y) and the status of the second switch, etc., the picture of the multi-function electromagnetic coil 106 in the area where the tablet is located (including the characters, patterns, etc. in the area) is locally enlarged, and the simulation is as true. The effect of a magnifying glass in the world. When the multi-function solenoid ring 106 moves to the next area, the originally enlarged picture will return to its normal size, and the newly moved area will be enlarged.

The third function is the oil painting drawing function (or the oil knife function). When the multi-function electromagnetic coil ring 106 is controlled by the second switch 110 to emit the electromagnetic signal frequency defined by the tablet as the oil drawing mode (or the canvas mode), as long as the state of the second switch 110 is not changed, The functional solenoid coil 106 will continuously emit an electromagnetic signal defined by the tablet as an oil drawing mode (or a canvas mode). Since the multi-function electromagnetic coil ring of the present invention is a circular or elliptical structure similar to the cutter head of a painting knife, it is different from the spiked nib or the dome-shaped eraser of the conventional electromagnetic pen, and can simulate the oil painting knife. Use different knife methods, such as pressing, dragging, wiping, scraping, etc., to create the oil painting effect.

When the electromagnetic signal of the oil painting drawing mode (or the painting knife mode) issued by the multi-function electromagnetic coil ring 106 is received in the tablet, the application corresponding to the oil painting drawing mode (or the painting knife mode) in the tablet will be based on The tablet transmits the mode ID, coordinates (X/Y), and the status of the second switch to push the color on the tablet screen toward the end of the electromagnetic pen (or the functional solenoid ring 106). The direction of the oil painting. In addition, in this oil painting drawing mode, it is also changed to the function of scraping the color on the canvas by the control of the second switch 110, and the color already applied on the tablet screen is scraped. In addition, repaint.

Of course, the tail end of the electromagnetic pen of the present invention (or the functional electromagnetic coil ring) is not limited to the above three functions or modes, but the corresponding application can be configured in the tablet according to requirements, and other functions are achieved, but The electromagnetic signal of each different frequency emitted by the device represents a different function and mode, and the electromagnetic signal frequency emitted by the function electromagnetic coil ring is controlled by the second switch disposed at the tail end portion of the pen body, thereby controlling the electromagnetic The function and mode switching of the end of the pen (or the function of the electromagnetic coil).

Therefore, the present invention provides an electromagnetic with a plurality of functional tails, since it is directly controlled by the side switches to control the opening and switching of its tail end functions, such as the opening of the erasing function, as long as it is above the tablet. The eraser does not need to be in contact with the tablet, so noise and damage are not generated due to friction between the electromagnetic pen and the tablet, and thus an elastic structure is not required, so the structure is simple and the cost is relatively low. In addition, since the electromagnetic pen can directly control the frequency of the electromagnetic signal emitted by the tail end (or the multi-function coil ring) by the side switch, the tail end can have several different functions.
