<First embodiment>
(1) Appearance of Input Touch Pen 5 The input touch pen 5 according to the first embodiment has an appearance as shown in FIGS. 1(A) and 2(A). FIG. 1A is a front view of the input touch pen 5 showing a separated state in which an oscillation frequency adjusting member 23, which will be described later, is separated from an electromagnetic induction coil 46, which will be described later, and FIG. FIG. 4 is a front view of the input stylus 5 showing an approaching state in which the adjusting member 23 approaches an electromagnetic induction coil 46 to be described later.

The input touch pen 5 has, as its external structure, a barrel 10 having openings at its front end and rear end. This barrel 10 constitutes a front end side in the axial direction, and a front barrel 12 formed in a tapered shape with a tapered front end portion is press-fitted from the front end of a rear shaft 14 constituting a rear end side in the axial direction. , the inner shaft 16 located on the rear end side of the rear shaft 14 is press-fitted from the rear end of the rear shaft 14 . At the tip of the front barrel 12, a tip opening 13 is formed as a tip opening to expose a contact tip 45 of an electromagnetic induction refill 40, which will be described later. A rear end opening 15 is formed through which an operation portion 32 of a knock mechanism 30, which will be described later, is exposed.

(2) Inside of input touch pen 5 FIG. 1(B) is a front view AA cross-sectional view of the input touch pen 5 showing the separated state, and FIG. 2(B) is a front view of the input touch pen 5 showing the close state. is a cross-sectional view taken along the line BB.

A cylinder 20 , a knock mechanism 30 for axially moving the cylinder 20 , and an electromagnetic induction refill 40 housed inside the cylinder 20 are housed inside the barrel 10 . However, among the constituent members of the electromagnetic induction refill 40, at least a contact tip 45, which will be described later, is exposed from the tip opening 13 without being housed inside the barrel 10, and among the constituent members of the knock mechanism 30, at least The operating portion 32 is exposed from the rear end opening 15 without being accommodated inside the barrel 10 .

Further, a contact portion 18 is provided on the rear shaft 14 slightly toward the rear end of the center in the axial direction, with which the electromagnetic induction refill 40 and a spring 17 (to be described later) come into contact with each other. The contact portion 18 has a concave portion 18A that is recessed from its front end to its rear end. Further, the contact portion 18 is formed with a passage hole 18B that is open along the axial direction for passage of the wide portion 21 of the cylindrical body 20, which will be described later.

A cam portion 16A is provided on the distal end side of the inner shaft 16 to engage with a later-described rotor 31 of the knock mechanism 30 .
The tubular body 20 has a tubular shape as a whole, and the inside thereof penetrates from the front end to the rear end. The cylindrical body 20 includes a wide portion 21 forming the rear end side and a narrow portion 22 forming the front end side and having an outer diameter smaller than that of the wide portion 21 . The outer diameter of the wide portion 21 is larger than the outer diameter of the electromagnetic induction refill 40 , and the outer diameter of the narrow portion 22 is slightly larger than the outer diameter of the electromagnetic induction refill 40 .

After the cylindrical body 20 is inserted until a part of the rear end side of the wide portion 21 passes through the passage hole 18B, the knock mechanism 30 is attached to the part of the rear end side of the wide portion 21 that has passed through the passage hole 18B. The rotor 31 is housed inside the shaft tube 10 by being connected to the tip of the rotor 31 . When the cylindrical body 20 is housed inside the barrel 10 , the rear end of the spring 17 is in contact with the front end of the rotor 31 , and the rear end of the contact portion 18 is in contact with the rear end of the spring 17 . The knock mechanism 30 and the cylindrical body 20 are always urged toward the rear end by the urging force of the spring 17 .

Here, on the outer circumference of the rear end side of the narrow width portion 22, there is an oscillation frequency that changes the frequency of the electromagnetic energy reflected by the electromagnetic induction refill 40, specifically, is electromagnetically coupled with the oscillation circuit inside the electromagnetic induction refill 40. An adjustment member 23 is attached. This oscillation frequency adjusting member 23 is composed of at least a coil and a capacitor. The oscillation frequency of the oscillation frequency adjusting member 23 is adjusted to be equal to that of the oscillation circuit inside the electromagnetic induction refill 40 .

The oscillation frequency adjustment member 23 reflects electromagnetic energy received from the position detection device at the same timing as the electromagnetic induction refill 40 . In the approaching state, the magnetic flux reflected by the oscillation frequency adjusting member 23 penetrates the electromagnetic induction coil 46 of the electromagnetic induction refill 40, which will be described later. The oscillation frequency of the inductive refill 40 changes.

The oscillation frequency adjusting member 23 in the first embodiment has a structure in which a coil is arranged in a tubular ferrite. The winding start and winding end of the coil that constitutes the oscillation frequency adjusting member 23 are connected to a substrate (not shown) on which a capacitor is mounted. The oscillation frequency adjusting member 23 is positioned inside the front barrel 12 when the cylindrical body 20 is accommodated inside the barrel 10 . Note that ferrite refers to an oxide magnetic material containing iron.

The knock mechanism 30 includes a rotor 31 arranged inside the inner shaft 16 and movable in the axial direction, and an axially movable operating portion exposed from the rear end of the inner shaft 16, that is, the rear end opening 15. 32 and . The knocking mechanism 30 moves the oscillation frequency adjusting member 23 in the axial direction with respect to the electromagnetic induction refill 40. Specifically, the knocking operation moves toward the electromagnetic induction coil 46 (front end side) and This is to move the oscillation frequency adjusting member 23 in the separating direction (rear end side). The knocking operation is performed by pressing the operating portion 32 toward the distal end side.

When a knocking operation is performed in the separated state (see FIG. 1), the rotor 31 is pushed forward by the movement of the operating portion 32, and the rotor 31 and the distal end surface of the cam portion 16A of the inner shaft 16 are engaged. Then, the input touch pen 5 is in the approach state (see FIG. 2). Further, when a knocking operation is performed in the approach state (see FIG. 2), the movement of the operating portion 32 presses the rotor 31 toward the tip side, and the rotor 31 engages with the tip surface of the cam portion 16A of the inner shaft 16. stop is released. As a result, the knock mechanism 30 and the cylindrical body 20 are moved toward the rear end by the biasing force of the spring 17, and the input touch pen 5 is separated (see FIG. 1).

The electromagnetic induction refill 40 reflects electromagnetic energy transmitted by an electromagnetic induction type position detection device, and has, for example, the following configuration. In the first embodiment, the diameter of the electromagnetic induction refill 40 is 3.2 mm. The electromagnetic induction refill 40 is provided with a housing cylinder 41 having openings at its front end and rear end. parts are installed.

A tip joint 44 made of synthetic resin is attached to the tip side of the housing tube 41 . A substantially tubular core holder 42 is incorporated in the tip joint 44 . A rod-shaped ferrite core 43 is inserted through the core holder 42 . A synthetic resin contact tip 45 is attached to the tip of the ferrite core 43 . Further, an electromagnetic induction coil 46 is arranged around the ferrite core 43 with a core holder 42 interposed therebetween.

A pressure sensor 47 electrically connected to an electromagnetic induction coil 46 and a capacitor 48 are accommodated in the interior space of the accommodation cylinder 41 on the rear end side of the ferrite core 43 . The pressure sensor 47 is a variable capacitor whose electrostatic capacity increases according to the writing pressure, and together with the capacitor 48 and the electromagnetic induction coil 46, constitutes an oscillation circuit. A rear end joint 49 made of synthetic resin is attached to the rear end of the storage tube 41 .

The rear end of the rear end joint 49 is fitted with an insertion portion 50 for insertion into the recess 18A of the contact portion 18 . The outer diameter of the insertion portion 50 is slightly narrower than the width (length in the radial direction) of the recess 18A. Therefore, by press-fitting the insertion portion 50 into the recess 18A, the insertion portion 50 and the contact portion 18, that is, the insertion portion 50 and the rear shaft 14 are connected. Thereby, the electromagnetic induction refill 40 is fixed to the rear shaft 14 and the electromagnetic induction refill 40 is housed inside the barrel 10 . When the electromagnetic induction refill 40 is accommodated inside the barrel 10 , the contact tip 45 is exposed from the tip opening 13 .

A return spring 51 is mounted around the insertion portion 50 to bias the housing cylinder 41 toward the distal end. The return spring 51 is compressed when the housing cylinder 41 moves to the rear end side as the contact tip 45 is pressed. In addition, since the electromagnetic induction refill 40 is detachably fixed to the rear axle 14 by the insertion portion 50, when the contact tip 45 is worn or the built-in electronic devices are broken, a new one can be easily replaced. can be exchanged for

(3) Action Next, the action of the first embodiment, specifically, the flow of inputting information to the input device 100 (eg, an electromagnetic induction tablet) shown in FIG. 4 by the electromagnetic induction refill 40 will be described. . The input device 100 is provided with an input surface 102 for input by the electromagnetic induction refill 40, and a position detection device for transmitting electromagnetic energy of a specific frequency is provided on the lower surface of the input surface 102. there is

The input device 100 according to the first embodiment also has a "writing mode" in which lines corresponding to handwriting traced with the input touch pen 5 are input as electronic information, and a portion corresponding to the handwriting traced with the input touch pen 5. An "erase mode" is provided in which electronic information is erased. The input device 100 switches between the above modes based on the frequency of the electromagnetic energy fed back from the input touch pen 5. In the first range, which is a predetermined frequency range, the "writing mode" is set. The second range, which has a lower frequency than the first range, is preconfigured to be set to the "erase mode".

Furthermore, the position detection device of the input device 100 is provided with a plurality of coils for transmitting electromagnetic energy to the electromagnetic induction refill 40 . On the other hand, the electromagnetic induction refill 40 is provided with an oscillation circuit (not shown) having a resonance frequency corresponding to the frequency of the transmission signal. The electromagnetic induction action of the coil of the position detecting device and the oscillation circuit (not shown) of the electromagnetic induction refill 40 allows the electromagnetic induction refill 40 to store electromagnetic energy.

The electromagnetic induction refill 40 feeds back electromagnetic energy stored in an oscillation circuit (not shown) to the position detection device. A position detection device detects electromagnetic energy from this electromagnetic induction refill 40 . Specifically, the position detection device detects the electromagnetic induction refill 40 based on the position of the coil that supplied the transmission signal and the position of the coil that detected the electromagnetic energy from the oscillation circuit (not shown) of the electromagnetic induction refill 40. Detect the indicated coordinate value.

Further, when the contact tip 45 of the electromagnetic induction refill 40 is pressed, the pressure sensor 47 is pressed and the capacitance increases. This slightly lowers the resonant frequency. The contact of the electromagnetic induction refill 40 is detected by the position detection device detecting a change in the resonance frequency of the electromagnetic induction refill 40 . With this, characters and the like can be drawn.

Here, in the separated state (see FIG. 3A), since the oscillation frequency adjusting member 23 is sufficiently separated from the electromagnetic induction coil 46, the degree of electromagnetic coupling with the oscillation circuit inside the electromagnetic induction refill 40 is reduced. It's small enough. Therefore, in the separated state, the oscillation frequency of the electromagnetic induction refill 40 does not change, and the input device 100 determines that it is within the first range, and sets the writing mode. Therefore, by tracing the input surface 102 of the input device 100 with the contact tip 45 in the separated state, a letter, for example, the letter "P" as shown in FIG. 4A can be drawn on the input device 100.

When a knocking operation is performed in the separated state, the rotor 31 is pushed forward by the movement of the operating portion 32, and the rotor 31 and the distal end surface of the cam portion 16A of the inner shaft 16 are locked, and the input touch pen 5 is moved. become close.

In the close state (see FIG. 3(B)), the oscillation frequency adjustment member 23 is close to the electromagnetic induction coil 46, and the frequency of the electromagnetic energy emitted by the input touch pen 5 is in the distant state (see FIG. 3(A)). ) is lower than that of Accordingly, the input device 100 determines that it is within the second range, and sets the erasing mode. Therefore, when part of the letter "P" described above is traced with the contact tip 45 in the approaching state, the electronic information of the letter "P" corresponding to the traced part is erased, and the input device The portion traced from the input surface 102 of 100 disappears (see FIG. 4B).
