Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a writing input device and a writing pen used for the writing input device.
[0002]
[Prior art]
In recent years, with the expansion of the market for information communication devices and business terminals, the demand for input devices that can easily input XY coordinates using a pen has been increasing. Here, the XY coordinates are not relative coordinates such as a mouse for relatively recognizing a movement amount, but are absolute coordinates (absolute plane coordinates) on a plane for directly recognizing a moved position. In the specification, they are simply referred to as plane coordinates.
[0003]
As the input method, a pen or a finger is used to directly press the pressure-sensitive input unit to write a written character or symbol as writing information, and the input method is integrated with the pressure-sensitive input unit or pressure-sensitive. There is a type in which the contents of a menu are input by pressing a pressure-sensitive input unit corresponding to a predetermined display portion of a display unit that displays a menu of input contents, which is provided on the input unit.
[0004]
A touch panel or a tablet is provided with a function for performing one of the writing information input method and the selected menu information input method, or a function for performing both of them, in one device.
[0005]
Further, as a display device for displaying input information, there are a display device using a display such as a CRT independent of the input device, and a display device in which a liquid crystal display unit is provided integrally with the input device.
[0006]
Looking at the situations where input devices are used, it is mainly used for personal use at home or workplace, and is shared by relatively few people such as family members and colleagues depending on the situation. Some are used by many people to sign or the like.
[0007]
In any of the various types of input devices described above, when writing information such as a signature is input using a pen, so-called good writing quality is required as in a general writing implement. In this case, the writing taste includes the degree of resistance when the pen is slid on the pressure-sensitive input part, in other words, the feeling of slipping or being caught, and the feeling of elasticity when the pen is pressed against the pressure-sensitive input part. Both are included.
[0008]
As described above, the writing quality is determined by the pressing pressure on the pressure-sensitive input unit, the friction when the pen slides on the pressure-sensitive input unit, and the like. For example, it has a close relationship with surface damage and the like.
[0009]
Several proposals have been made to improve the writing taste of such a writing input device by devising a pen to be used.
[0010]
For example, there has been proposed a touch pen in which an elastic member such as rubber or a spring is provided at a position where the pen tip and the body are fixed. According to this touch pen with pen pressure adjustment mechanism, it is easy to write even if a person who has a habit of writing by pressing strongly when writing characters with a pen puts effort, and at this time, unreasonable power is not applied to the LCD screen It is said that the liquid crystal screen is hardly broken (see Patent Document 1).
[0011]
Further, for example, there has been proposed a structure in which a touch ball made of resin is provided at a pen tip of an input pen, and the touch ball is held via a spring. According to this input pen, even when the pen is pressed against the surface of the touch panel with a strong writing pressure, the force is reduced by the spring, which suppresses the deformation of the soft touch ball, thereby providing excellent usability and damaging the display. (See Patent Document 2).

[0044]
First, a handwriting input device according to a first example of the present embodiment will be described with reference to FIGS.
[0045]
The writing input device according to the first example of the present embodiment is, for example, a resistive touch panel. The invention is not limited to this, and may be an electromagnetic induction system, an electrostatic coupling system, or the like, or may be a tablet.
[0046]
The handwriting input device 10 includes a device main body 12 and a processing unit 13.
[0047]
The apparatus main body 12 is provided with pressure-sensitive input sections 14a and 14b constituting a plane coordinate input mechanism on each of two main surfaces.
[0048]
Each of the pressure-sensitive input units 14a and 14b has a resin sheet 18 and a glass plate 20 provided with resistance films 16a and 16b over substantially one side thereof. The sheet 18 of the pressure-sensitive input unit 14a and the sheet 18 of the pressure-sensitive input unit 14b are set to have different sliding resistances when sliding a writing pen. Such adjustment can be performed by making the surface roughness of the sheet 18 different, for example, by selecting a sheet having a different surface roughness of the surface hard coat layer. In order to make the surface roughness of the sheet 18 different, for example, for one sheet, a material having a smooth surface formed by using a resin material as it is is selected, and for the other sheet, for example, an acrylic layer is formed on the hard coat layer. A material obtained by dispersing matte (matte) particles in a resin material by mixing system particles or the like is subjected to a molding process, and a so-called non-glare surface-treated material in which the matte particles are exposed on the surface is selected. Note that the pressure-sensitive input units 14a and 14b may use sheets instead of the glass plate 20, thereby making the device thinner.
[0049]
On the resistive film 16a of the sheet 18 of the pressure-sensitive input sections 14a and 14b, electrodes 22a and 22b made of a transparent conductive film such as an ITO film are disposed on the peripheral edge of the sheet 18 facing the input area. In the resistance film 16b, electrodes 22c and 22d are arranged in a direction perpendicular to the electrodes 22a and 22b at a peripheral portion opposed to the center input range (in FIG. 3, for convenience, they are arranged on the same plane). Four electrodes are shown.). The sheet 18 and the glass plate 20 are attached to the apparatus main body 12 with the sides on which the resistive films 16a and 16b are provided facing each other and separated by a predetermined distance. The resistive film 16b on the glass plate 20 side is preferably provided with countless dot spacers 24.
[0050]
In FIG. 3, for example, electrodes 22a and 22b parallel to the X axis detect a divided voltage indicating the Y coordinate, and electrodes 22c and 22d parallel to the Y axis detect a divided voltage indicating the X coordinate. Used respectively.
[0051]
The processing unit 13 included in the handwriting input device 10 processes the input handwriting information signal, that is, the processing unit (A) that converts the absolute coordinate values (analog signals) from the pressure-sensitive input units 14a and 14b into digital signals. MCU), and only one is provided for the two pressure-sensitive input units 14a and 14b. The processing unit 13 is provided with a transistor that applies a voltage between the electrodes of the resistance films 16a and 16b (not shown). The processing unit 13 further includes a control unit that controls the transistor and a voltage detection unit that detects a voltage value corresponding to the contact position (not shown), and detects coordinates. It is not excluded that two processing units are provided corresponding to the two pressure-sensitive input units 14a and 14b.
[0052]
The apparatus main body 12 and the processing unit 13 are connected by a cable 26. The cable 26 accommodates electric wires connecting the electrodes of the pressure-sensitive input units 14 a and 14 b and the processing unit 13.
[0053]
The device main body 12 is provided with a changeover switch 28 that can switch the connection between the pressure-sensitive input units 14a and 14b and the processing unit 13. That is, the connection of the electric wires 30a and 30e connected to the electrodes 22a and 22a of the pressure-sensitive input units 14a and 14b to the electric wire 32a connected to the processing unit 13 is switched by the contact portions 28a and 28e of the changeover switch 28. Hereinafter, similarly, the connection between the electric wire 30b and the electric wire 30f and the electric wire 32b by the contact portions 28b and 28f, the connection between the electric wire 30c and the electric wire 30g and the electric wire 32c by the contact portions 28c and 28g, and the contact portions 28d and 28h The connection between the electric wires 30d and 30h and the electric wires 32d is thereby switched. Thus, by switching the changeover switch 28, the pressure-sensitive input unit to be used among the pressure-sensitive input units 14a and 14b can be electrically connected to the processing unit 13.
[0054]
In addition to the changeover switch 28, the apparatus main body 12 is further provided with an intermittent switch 34. Thus, by turning on / off the intermittent switch 34, the pressure-sensitive input unit and the processing unit 13 can be electrically connected or cut off.
[0055]
The operation of the handwriting input device 10 according to the first example of the present embodiment configured as described above will be described below.
[0056]
Using a writing pen to be described later, for example, by pressing one point in the input range of the pressure-sensitive input unit 14a arranged upward in the state of FIG. 1 and writing a dot symbol, the pressed contact point Then, the two resistive films 16a and 16b come into contact with each other, the voltage is divided at the contact points, and the voltages indicating the X coordinate point and the Y coordinate point are output. Writing input information is detected. When a pen is slid on the pressure-sensitive input unit 14a to draw a continuous line or a discontinuous line and a character is written in a state where one point in the input range of the pressure-sensitive input unit 14a is depressed, the character is written in the same manner as described above. In the processing device 13, the handwriting input information of the character which is the XY plane coordinate data is detected.
[0057]
The detected handwriting input information is temporarily stored in a storage unit of the computer, and is post-processed as necessary. The detected handwriting input information is displayed on a display or the like provided in the computer.
[0058]
The writing input device 10 according to the first example of the present embodiment described above can select and adjust the degree of sliding of the pen by selecting and using one of the pressure-sensitive input units 14a and 14b. Thereby, it is possible to respond to the taste of the writer.
[0059]
Further, in the handwriting input device 10, since a plurality of pressure-sensitive input portions are provided on the two main surfaces of the front and back of the device main body, an increase in the thickness of the device main body caused by providing the plurality of pressure-sensitive input portions is reduced. be able to. It is not excluded that a plurality of pressure-sensitive input units are provided at locations other than the two main surfaces of the front and back of the apparatus main body.
[0060]
In addition, the handwriting input device 10 switches a changeover switch to share one processing unit with two pressure-sensitive input units, so that there is no need to provide two processing units.
[0061]
In addition, the writing input device 10 can turn off the intermittent switch at the time of trial writing to test writing taste, thereby avoiding the inconvenience that the writing information of the trial writing is output to the processing unit.
[0062]
Here, as a modification of the changeover switch 28 of the handwriting input device 10, an automatic changeover switch 38 will be described with reference to FIG.
[0063]
As the automatic changeover switch 38, for example, a reed switch is used. The automatic changeover switch 38 is accommodated in a hole 42 provided in the apparatus main body 12 by the magnet 40 so as to be movable in two main surface directions, in other words, in the thickness direction of the apparatus main body 12. A set 44 of reed switches corresponding to the contact portions 28a to 28d and a set 46 of reed switches corresponding to the contact portions 28e to 28h of the changeover switch 28 in FIG. Provided.
[0064]
Thereby, as shown in FIG. 4, when the apparatus main body 12 is arranged on a table or the like with the pressure-sensitive input section 14a facing upward so as to use the pressure-sensitive input section 14a, the magnet 40 is moved to the lower part of the apparatus main body 12 by gravity. Descends. Thus, the reed switch set 44 is turned on and the reed switch set 46 is turned off at the same time, and the pressure-sensitive input unit 14a and the operation unit 13 are automatically electrically connected. Therefore, the trouble of switching the changeover switch 28 is omitted.
[0065]
Here, as shown in FIG. 4, the apparatus main body 12 is provided with a protruding portion 48 made of, for example, rubber, which has elasticity at a peripheral edge of the surface of the apparatus main body which faces downward when used. It is possible to reduce the impact that can be received when the device is placed on the like. In addition, in the handwriting input device 10, since the two pressure-sensitive input portions 14a and 14b are provided on the two main surfaces of the device main body 12, the protruding portion 48 is provided on the upper surface of the device main body 12 in FIG. Can be
[0066]
In the handwriting input device 10 according to the first example of the present embodiment, the sheet 18 is formed of a transparent material, and is separated from the pressure-sensitive input units 14a and 14b at the periphery of the input range on the surface of the glass plate 20; Independently, a configuration may be adopted in which a touch input unit is provided in which a display content is input by touching a specific display portion with a pen.
[0067]
Next, a writing input device according to a second example of the present embodiment will be described with reference to FIGS.
[0068]
The basic configuration of the handwriting input device 50 according to the second example of the present embodiment is the same as that of the handwriting input device 10 according to the first example of the present embodiment. The writing input device 10 differs from the writing input device 10 in that a cover sheet (sheet) 52 is further provided on the sheet 18. The pressure-sensitive input section 14b provided on the main surface on the back side of the apparatus main body 12 (omitted in FIG. 5) has a configuration in which a cover sheet 52 is further provided on the sheet 18 similarly to the pressure-sensitive input section 14a. Alternatively, the pressure-sensitive input unit 14b may be left as it is.
[0069]
When the cover sheet 52 is provided in each of the pressure-sensitive input units 14a and 14b, in the writing input device 10 according to the first example of the present embodiment, in the same manner as described for the sheet 18, two cover sheets 52 are provided. Are set so that the magnitude of the sliding resistance when the writing pen is slid is different. On the other hand, when the pressure-sensitive input unit 14b is used as it is, the sliding resistance when the writing pen slides on the cover sheet 52 of the pressure-sensitive input unit 14a and the sheet 18 of the pressure-sensitive input unit 14b. Are set to be different.
[0070]
The cover sheet 52 may be provided on the pressure-sensitive input sections 14a and 14b by a method of fixing the cover sheet 52 to the sheet 18 using a normal adhesive. However, as shown in FIG. The cover sheet 52 to which one surface is fixed is attached to the sheet 18 via the slightly adhesive material 54, or the cover sheet 52 is attached to the slightly adhesive material 54 of the sheet 18 to which one surface of the slightly adhesive material 54 is fixed. Is also good. As such a slightly adhesive material 54, for example, a resin sheet obtained by applying a silicone-based adhesive having slight adhesiveness to a PET film on one surface can be used. An agent is applied and adhered to the cover sheet 52 or the sheet 18. When the cover sheet 52 is detachably attached to the sheet 18, that is, the pressure-sensitive input sections 14a and 14b, a large number of cover sheets 52 having different sliding resistances when sliding a writing pen are prepared. In this way, a desired cover sheet 52 can be appropriately selected, detached and used easily.
[0071]
The handwriting input device 50 according to the second example of the present embodiment described above has the same effects as the handwriting input device 10 according to the first example of the present embodiment. In particular, by attaching and detaching a large number of cover sheets 52, writing taste can be finely adjusted, and it is possible to cope with an unspecified number of users' preferences.
[0072]
Next, in the handwriting input device 50 according to the second example of the present embodiment, as shown in FIG. 7, if a sheet storage portion 56 is provided in the device main body 12, the unused cover sheet 52 can be stored. Thus, for example, scattering of a large number of cover sheets 52 can be prevented. At this time, it is more preferable that the apparatus main body 12 is further provided with a pen storage section 58 for storing a writing pen.
[0073]
Next, a handwriting input device 60 according to a third example of the present embodiment will be described with reference to FIG.
[0074]
The handwriting input device 60 according to the third example of the present embodiment has two pressure-sensitive input portions 62 provided on one main surface of the device main body 12, in other words, a pressure-sensitive input portion region divided into two. The points provided separately as 62a and 62b are different from the handwriting input device 10 according to the first example of the present embodiment and the handwriting input device 50 according to the second example of the present embodiment.
[0075]
At this time, the sheet corresponding to the sheet 18 in the first example of the present embodiment and the like, in which the pressure-sensitive input section regions 62a and 62b are disposed separately from each other on the glass substrate, use a writing pen. It may be configured so that the magnitude of the sliding resistance when sliding is different, and the cover in the first example and the like of the present embodiment is further provided on the pressure-sensitive input section regions 62a and 62b. Sheets corresponding to the sheets 52 may be provided, and these sheets may be configured to have different sliding resistances when the writing pen is slid. Note that it is not necessary to provide a pressure-sensitive input unit on the main surface (back surface) of the device main body 12 opposite to the main surface on which the pressure-sensitive input unit 62 is provided. A part may be provided.
[0076]
The writing input device 60 according to the third example of the present embodiment can obtain the same effects as those of the first or second example of the present embodiment, and can perform a procedure such as inverting the device body. By simply moving the position of the pen without stepping, it is possible to perform writing input with different writing styles.
[0077]
In the handwriting input device 60 according to the third example of the present embodiment, when the pressure-sensitive input unit 62 has a relatively large area, for example, the input area is configured by only one pressure-sensitive input unit. The sheet corresponding to the sheet 18 of the pressure-sensitive input section may be divided into two types of sheet sections having different writing tastes, or a sheet corresponding to the cover sheet 52 to be overlapped on the sheet 18 of the pressure-sensitive input section may be written. The cover sheets may be divided into two types with different tastes.
[0078]
Next, a handwriting input device 64 according to a fourth example of the present embodiment will be described with reference to FIGS.
[0079]
The writing input device 64 according to the fourth example of the present embodiment is different from the other examples described above in that the writing assistance pattern display unit 66 is provided in the pressure-sensitive input unit 14a.
[0080]
That is, the handwriting input device 64 is configured similarly to the handwriting input device 50 according to the second example of the present embodiment in FIG. 5 as shown in FIG. 9, for example, and furthermore, the glass plate of the pressure-sensitive input unit 14 a. A writing assistance pattern display section 66 displaying patterns such as lines, symbols, and characters is formed on the surface of the printing sheet 20 by a printing method or the like. Note that the writing assist pattern display section 66 may be formed at a position other than the front surface of the glass plate 20, and for example, the back surface side of the glass plate, the front surface or back surface side of the sheet 18, the back surface side of the cover sheet 52, and the like. Can be formed appropriately. In particular, when the writing assist pattern display section 66 is formed on the back surface side of the cover sheet 52, the plurality of cover sheets 52 can be used as a template, so to say, the writing assist pattern display section on which the desired display is made is appropriately selected. Can be. Note that, on the other main surface of the device main body of the handwriting input device 64, a handwriting assisting pattern display unit may be provided or may not be provided.
[0081]
The writing assist pattern display unit 66 displays a predetermined writing assist pattern in order to reduce problems when writing is input to the plain pressure-sensitive input unit, and serves as a guide when writing.

For example, as shown in FIG. 10, when requesting a signature from an unspecified number of people at a store or the like, the writing assisting pattern display unit 66a may provide an address (Your Address) and a name ((Your Signature)) so as to easily sign. It is preferable that the portion where the user writes the information is displayed in a frame as a writing assistance pattern.
[0083]
Further, as shown in FIG. 11, for example, the writing assist pattern display unit 66b displays ruled lines as a writing assist pattern so that the arrangement of the written characters or the like is not disturbed or is easy to write. Is also good. In addition to these, an appropriate display serving as a guide when writing can be performed.
[0084]
