DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an example of a digitizer applied to the present invention will be described with reference to FIGS. This digitizer is basically disclosed in Japanese Patent Application No. 61-213970 (Japanese Patent Application Laid-Open No. 63-703) previously filed by the present applicant.
No. 26) and Japanese Patent Application No. 1-282852 (Japanese Patent Laid-Open No. 3-28285).
However, the present invention is not limited to this type of digitizer.

The digitizer includes a coordinate detecting section 1 in which a plurality of loop coils are arranged, and a switching section 2 for selectively switching a predetermined loop coil among the plurality of loop coils in a preset order. A transmission circuit 3 for supplying an AC signal of a predetermined frequency to the loop coil via the switching unit 2 and a reception circuit 4 for receiving an induction signal induced in the loop coil, and the switching unit 2, the transmission circuit 3 and the reception circuit. 4, a control unit 5 for controlling timing and the like, a processing unit 6 for processing transmission / reception signals of the transmission circuit 3 and the reception circuit 4, and an interface unit 7 connected to a host computer including, for example, a central processing unit (CPU). (The above is the sensor side), and the input pen 8 as the coordinate indicator shown in FIG.

FIG. 2 illustrates a specific configuration of the coordinate detecting section 1 and the switching section 2. In the coordinate detection unit 1, a plurality of loop coils formed in a substantially rectangular shape are arranged in a matrix along the XY direction, but in the same figure, for example, in a horizontal row along the X direction. The arrangement is shown in FIG. According to this embodiment, the loop coils in one row are divided into three groups A, B and C, each including eight loop coils. That is, the group A has loop coils A0 to A7, the group B has loops B0 to B7, and the group C has loop coils C0 to C7.

One end of each loop coil of groups A, B, and C is connected to the eight selection terminals of the analog switches 21, 22, and 23, and the other end is connected to a common ground terminal. Analog switch 21,2
The switching terminals 2 and 23 are commonly connected to the switching terminal of the analog switch 24. Also, the analog switch 2
The two selection terminals 4 are connected to the transmission circuit 3 and the reception circuit 4. It should be noted that each of the analog switches 21 to 24 connects its switching terminal to one selection terminal in accordance with the switching signal sent from the control unit 5.

Here, each loop coil A0 of group A
The connection between A7 and the selection terminal of the analog switch 21 is in the order of the terminal numbers, that is, "0, 1, 2, 3, 4, 5, 6,
7 ”in order, but loop coil B of group B
0 to B7 are, for example, terminal numbers “0, 2, 1, 4, 3, 6,
5, 7 ”are connected to the selection terminals of the analog switch 22 in this order, and the loop coils C0 to C0 of the group C are also connected.
C7 is, for example, terminal number "2,0,4,1,6,3,7,
5 ”in this order are connected to the selection terminal of the analog switch 23.

This is the analog switch 21, 22,
This is because the relative positions of the loop coils selected simultaneously by 23 are not more than a predetermined number, in this example, four or more, so as not to be the same or symmetrical within each group and across the groups.

That is, the loop coil connected to the selection terminal of the terminal number "0, 1, 2, 3, 4, 5, 6, 7" of each analog switch is "X0, X1, X2, X3, X.
4, X5, X6, X7 ", for example, when the relative position (arrangement) of" X0, X1, X2, X3 "by the loop coils A0 to A3 is in another group or across two groups. Does not exist in the
There is no line of "2, X1, X0".

In this embodiment, as shown in FIG. 3, the coordinate detecting section 1 has a case 11 made of non-metal, and the case 11 has a loop coil group LX in the X direction and a Y direction. The loop coil group LY is housed, and a flat display 12 including a liquid crystal display panel, the display of which is controlled by a computer (not shown), is provided in the upper opening of the loop coil group LY. The display 12 does not necessarily have to be integrated with the coordinate detection unit 1 as in this embodiment, and a display of a personal computer or the like may be used.

As shown in FIG. 4 (a), the input pen 8 as a coordinate indicator has a grip 81 made of a non-metal material such as synthetic resin, and the tip end inside the grip 81. A ferrite core 82 having a through hole is provided, and a stylus 83 is slidably held in the through hole.
The stylus 83 is biased in the protruding direction by a spring member (not shown).

A coil 84 is provided around the ferrite core 82.
Is wound, and a variable capacitor 85 whose capacitance is changed by the stylus 83 and a fixed capacitor 86 connected in parallel to the variable capacitor 85 are provided at the rear end of the stylus 83. Has been.
In addition, a switch 87 for displaying a menu is provided at a predetermined portion of the clip 81, and the switch 87 is a capacitor 8
8 is connected in parallel to the capacitors 85 and 86.

The above coil 84 and capacitors 85 and 86
And a capacitor 88 selectively connected via switch 87 allows tuning circuit 8 as shown in FIG.
0 is configured. As illustrated in FIG. 4B, the variable capacitor 85 has a deformable first electrode 851 made of conductive rubber or the like and an electrically insulating spacer 853 sandwiched between the first electrode 851 and the deformable first electrode 851. The stylus 83 presses and deforms the first electrode 851, which has the second electrode 852 disposed so as to face each other, thereby changing its electrostatic capacitance, thereby detecting the writing pressure.

The resonance frequency of the tuning circuit 80 is selected to be a value that is tuned to the frequency of the radio wave transmitted from the loop coil of the coordinate detecting section 1. The switch 87 is turned on and the coil 84 and the capacitor are turned on. By adding the capacitor 88 to the parallel resonant circuit composed of 85 and 86,
The phase of the radio wave in the parallel resonance circuit is delayed by a predetermined angle, for example 90 °, and this is sent to the sensor side as an operation menu display request signal.

Now, the operation of the processing section 6 of this digitizer will be described. First, each unit is reset and the transmission circuit 3 generates an AC signal having a predetermined frequency. Next, set the analog switches 21, 22, and 23 to the terminal numbers "0, 1,
2, 3, 4, 5, 6, 7 ”are sequentially sent to the control unit 5, and the coordinate detection unit 1 is sent to the control unit 5.
And outputs an instruction to transmit and receive a radio wave between the input pen 8 and the input pen 8.

Based on this, the control unit 5 first outputs a selection signal for selecting the terminal number "0" to each of the analog switches 21, 22 and 23, and also sends a transmission circuit to the analog switch 24. The signal for selecting the 3 side is transmitted. As a result, an AC signal having a predetermined frequency is supplied from the transmission circuit 3 to the loop coil A0 of the group A, the loop coil B0 of the group B, and the loop coil C1 of the group C, and radio waves are transmitted from each of the loop coils. After a predetermined time, the analog switch 24 is switched to the receiving circuit 4 side.

Thereafter, similarly, each analog switch 21, 2
The terminal numbers of 2 and 23 are sequentially switched, and transmission and reception are performed for the selected loop coil.
When the input pen 8 is placed on a specific loop coil,
A radio wave from the loop coil excites the coil 84 of the input pen 8 to generate an induced voltage in the tuning circuit 80 in synchronization with the frequency of the transmitting circuit 3.

When the loop coil is switched to the receiving circuit 4 side by the analog switch 24, the radio wave from the loop coil immediately disappears, but the induced voltage generated in the tuning circuit 80 of the input pen 8 depends on the loss. And gradually attenuates, and the coil 84 generates a radio wave. This radio wave excites the loop coil in the opposite direction, which causes an induced voltage in the loop coil. The receiving circuit 4 receives this, and the processing unit 6 determines which group of loop coils the input pen 8 is placed on, based on the pattern of the appearance of the induced voltage.

In this way, the position of the input pen 8 on the coordinate detecting section 1 is detected and the position signal is transmitted to the host computer (not shown) via the interface section 7. Here, for example, When the switch 87 is turned on, as shown in FIG. 6, a plurality of operation menus M are displayed on the display 12, for example, in a concentric pattern with the designated position of the input pen 8 as a starting point.

FIG. 7 shows a specific example of the display, and the desired operation menu M is selected from the display example.
This is performed by adjusting the writing pressure of the input pen 8. That is, the electrostatic capacitance of the variable capacitor 85 changes according to the magnitude of the writing pressure, and the coil 84 of the tuning circuit 80 is accordingly changed.
The frequency and phase of the radio wave transmitted from the device changes. Using this as a selection signal, in this embodiment, as the writing pressure is increased, the operation menu is sequentially selected from the center toward the outside (in the example shown, the order is File → Edit → Display → Help). On the other hand, by weakening the writing pressure, the operation menu M is sequentially selected from the outside toward the center (in the illustrated example, the order of help → display → edit → file).

In this way, by changing the writing pressure to select a desired operation menu M (for example, "edit" menu), the switch 87 is released (turned off) to determine the operation menu M. To be done.

In contrast to this, for example, by turning on the switch 87, the menu selection mode is set, and the operation menu M is displayed so that the concentric circles gradually expand as the writing pressure is increased, and the desired operation menu is displayed. The switch 87 may be turned off at the time of display, and the operation menu may be selected.

On the other hand, by sliding the input pen 8 onto a desired operation menu and turning off the switch 87, the menu can be selected without depending on the writing pressure as described above. it can.

By the way, since the axis of the coil 84 of the tuning circuit 80 is the same as the axis of the input pen 8, the input pen 8 is moved from the vertical line H to the coordinate detecting section 1 as shown in FIG. When the coil 84 is tilted by a predetermined angle θ, as shown in FIG. 8, in addition to the main peak voltage Va serving as the pointing position information, a side lobe-like sub-direction is generated in the tilted direction of the coil 84 on the coordinate detection unit 1 side. The peak voltage Vb appears.

In the present invention, the direction in which the input pen 8 is tilted is detected by the sub-peak voltage Vb, and the operation menu M is displayed in relation to that direction. FIG. 9 shows an example in which the operation menu M is expanded in a fan shape in the direction opposite to the tilt direction with the designated position of the input pen 8 as the starting point, while FIG. 10 shows the same direction as the tilt direction. An example in which the operation menu M is expanded in a fan shape is shown.

Also in these embodiments, the desired operation menu is selected by the writing pressure, and the operation menu is determined by turning off the switch 87. Note that the input pen 8 may be slid onto a desired operation menu regardless of the writing pressure, and the switch 87 may be turned off to select that menu. In addition to this, the operation menus M may be expanded in a direction orthogonal to the tilt direction of the input pen 8, and instead of the fan shape, the operation menus M are displayed in a line as shown in FIG. You can also do so.

When both the tilt direction of the input pen 8 and the writing pressure can be detected, for example, a concentric circle is divided into four, and "edit" and "print" are made in the central portion, as shown in FIG.
The main menus of “function” and “file” are assigned and submenus belonging to the main menus are displayed outside the main menus.

Then, the main menu, for example, "edit" is selected according to the tilt direction of the input pen 8 and any one of "copy", "move" and "delete" of the submenu is determined by the pen pressure. The input pen 8 may be slid onto a desired submenu to determine the submenu regardless of the writing pressure. In the example of FIG. 12, the display is concentric, but it may be fan-shaped.

In the above embodiment, the operation menu M is expanded starting from the pointed position of the input pen 8; however, as shown in FIG.
If the operation menu MF is displayed at a fixed position in the
By inputting one of the operation menus with the input pen 8, the sub-menu MF of the subordinate menus belonging to the operation menu
It is preferable that 1 is displayed in a semi-concentric shape and that a desired menu can be selected by the writing pressure of the input pen 8.

Next, as shown in FIG. 14, when the coordinate indicator 9 is attached to each finger to perform input work or graphic work, an embodiment of a method of displaying an operation menu required for the work Will be described.

First, as shown in FIG. 15, the coordinate indicator 9 includes a coil 91 attached to the fingertip of the hand.
And a switch 92 that is turned on and off as the fingertip touches and separates from the coordinate indicator 1, and a capacitor 93 that forms a tuning circuit (resonance circuit) together with the coil 91. Although each of the coordinate indicators 9 may be directly attached to each finger, it is actually attached to the tip of each finger portion of a glove (not shown) and is attached by fitting the glove into a hand. Preferably.

In this case, as shown in the circuit diagram of FIG. 16, the capacitor 93 has two capacitors 931 and 9
32 and one capacitor 931 is connected to both ends of the coil 91, while the other capacitor 93
2 is connected in parallel to the capacitor 931 via the switch 92. Therefore, when the switch 92 is turned on and off, the tuning (resonance) frequency is different, and for example, the signal when the switch 92 is turned on is used as the operation menu display request signal. A unique tuning frequency is assigned to each coordinate indicator 9, and each position can be recognized on the computer side.

According to this embodiment, the main menu is selected by the left hand and the sub menu is selected by the right hand in FIG. 14, for example. Here, the coordinate indicator attached to each finger of the left hand is 9A to 9E from the thumb to the little finger, and the coordinate indicator attached to each finger of the right hand is 9a to 9e from the thumb to the little finger.

First, by pressing the coordinate indicator 9A of a specific finger, for example, the thumb of the left hand and turning on the switch 92 thereof, for example, "graphic" or "graphic" is displayed at the indicated position of the coordinate indicators 9A to 9E of the fingers of the left hand. Main menus such as "Copy", "Format", "Edit" and "Display" are displayed. Then, when the main menu "copy" is selected by the coordinate indicator 9B of the left hand, for example, the index finger, "part", "one character", "all" at each position of the coordinate indicators 9a to 9e from the thumb to the middle finger of the right hand. Submenus such as "enlarge" and "reduce" are displayed, and the submenu is selected by turning on the switch of the finger coordinate indicator 9 corresponding to the desired submenu.

Although the left-hand side displays the main menu and the right-hand side displays the sub-menu in the above embodiment, if the number of menus is large, ten coordinate indicators 9A are used.
9E, 9a to 9e may be used to display the main menu or the sub menu. That is,
First, by pressing a coordinate indicator of a specific finger (for example, the coordinate indicator 9A of the left thumb), the operation menu display mode is set, and the coordinate indicators 9A to 9A provided on the fingers of the left and right hands are displayed. The main menu is displayed on 9E, 9a to 9e, and the screen is switched by selecting one of them, and this time, each coordinate indicator 9A to 9E, 9a to.
The sub menu may be displayed on 9e.

Although the respective embodiments of the present invention have been described above, the computer has a learning function and is used (selected).
When the input pen 8 is used, a frequently-used menu is displayed in the vicinity of the designated position. On the other hand, in the finger input method using the coordinate indicator 9, it is displayed such that it is easy to move, for example, the position of the index finger or the middle finger. Good to do.

Also with the input pen 8, it is possible to display the main menu first, and if the main menu is selected, then the screen can be switched to expand the submenu of the main menu.
