It is composed of.

In addition, in the coordinate indicating pen with a pen pressure sound generation mechanism, the interval between sounds is changed by a control signal from a signal control section instead of the pen pressure generation display section and the main body case of the coordinate indicating pen with a pen pressure display mechanism.

It consists of a main body case that houses a magnetic detection sensor section and a signal control section.

〔Example〕

Embodiments of the present invention will be described based on the drawings.

First, a coordinate indicating pen with a writing pressure display mechanism according to the present invention will be explained.

FIG. 1 is a sectional view showing the main parts of a coordinate indicating pen with a writing pressure display mechanism according to an embodiment of the present invention, FIG. 2 is a diagram showing the operation of this sectional view, and FIG. 3 is an operation of the switch contactor. Figure 4 showing
The figure is a circuit diagram showing a writing pressure display mechanism, and FIG. 5 is a perspective view of one embodiment of the tablet device.

In FIG. 5, the coordinate display pen with pen pressure display mechanism of this embodiment inputs coordinates on the touch panel surface 14 of the tablet unit 13, and has a point indicating contact l, a point indicating contact compression coil spring 4, and a permanent It consists of a magnet 5, a magnetic detection sensor section 6, a signal control section 8, a pen pressure light emitting display section 9, and a main body case All.

In FIGS. 2 and 3, the main body case All includes an accommodating section for accommodating a point indicating contact compression coil spring 2 and a stop compression coil spring 4, an individual magnetic detection sensor section 6, a signal control section 8, and a pen pressure A housing portion is provided inside to house the light emitting display portion 9 so as not to move. Further, a point indicating contact compression coil spring 2 is wound around the shaft portion of the point indicating contact 1, and the point indicating contact 1 is connected to the main body case All by the point indicating contact compression coil spring 2.
A point indicating contact stopper movable portion 11a is provided inside which allows the point indicating contact stopper 1a to move so that the point indicating contact stopper 1a is in a state where it is pushed out a certain length from the main body case All and is not pushed into the main body case All for a certain length. There is.

The signal control unit 8 is brought into contact with the magnetic detection sensor part 6 and the pen pressure light emitting display unit 9, and the point indicating contact 1 is pushed and moves against the spring force of the point indicating contact compression coil spring 2.
The permanent magnets attached to the side surface of the shaft approach the magnetic detection sensor section 6b from the magnetic detection sensor section 6a, and further move to the magnetic detection sensor section 6c. When the permanent magnet 5 approaches each magnetic detection sensor section 6, the signal of each sensor changes, and the signal control section 8 detects the change in the signal and outputs a signal to the outside through the pen pressure signal line 12. A pen pressure light emitting display signal is sent to the pressure light emitting display section 9 through a pen pressure output signal line 10 to change the light emitting display.

Stop pressing the point indicating contact 1, and the spring force of the point indicating contact compression coil spring 2 causes the permanent magnet 5 to move from the magnetic detection sensor section 6c to the magnetic detection sensor section 6b, and then to the magnetic detection sensor section 6a. When the user moves, the magnetic detection sensor signal changes and the light emitting display section of the pen pressure light emitting display section 9 changes. When each magnetic detection sensor unit 6 detects the magnetic force of the permanent magnet 5, it outputs a signal from each sensor. The output signals from these individual sensors are magnetic detection sensor signals 1417 (7a, 7b).

7c) and is sent to the signal control unit 8. Signal control section 8
receives signals from the individual magnetic detection sensor sections 6,
Outputs a pen pressure light emission signal and a control signal for the pen pressure signal. The pen pressure changes into a magnetic detection signal, which is output by the signal control section 8 to the pen pressure light emitting display section 9 and the outside. Pen pressure light emitting display section 9
is displayed by changing the display on the light emitting display section in proportion to the increase/decrease in the control signal from the pen pressure display signal.

When the coordinate indicating pen with pen pressure display mechanism is pressed against the touch panel surface 14 with a force above a certain level, the main body case All moves relative to the touch panel surface 14, and the permanent magnet 5 on the side surface of the shaft of the point indicating contact 1 moves. The light emitting display of the pen pressure light emitting section 9 changes depending on the strength of the pressing force when approaching each magnetic sensor section 6.

Next, a coordinate indicating pen with a writing pressure sound generating mechanism according to the present invention will be explained.

FIG. 6 is a sectional view showing the main parts of a coordinate indicating pen with a pen pressure sound generation mechanism according to an embodiment of the present invention, FIG. 7 is a circuit diagram showing the pen pressure sound generation mechanism, and FIG. 8 is a diagram of a tablet device. FIG. 9, a perspective view of one embodiment, is a diagram showing the number of pulses per second when each magnetic sensor detects pen pressure.

FIG. 8 differs from FIG. 5 only in the main body case B21.

Also, in FIG. 6, the pen pressure sound generation section 22 is different from that in FIG. 1, and in FIG. 7, compared to FIG. The only difference is that it is a signal.

Therefore, the other individual configurations and operations are the same as the coordinate indicating pen with a pen pressure display mechanism, and in the coordinate indicating pen with a pen pressure sound generating mechanism, the pen pressure is output to the pen pressure sound generating section 22 and the outside. . Here, the pen pressure sound generation section 22 changes the sound generation interval in proportion to the increase or decrease of the control signal from the pen pressure sound generation signal.

When the coordinate indicating pen with a writing pressure sound generating mechanism is pressed against the touch panel surface 14 with a force above a certain level, the main body case B21 moves relative to the touch panel surface 14, and the permanent magnet 5 on the side surface of the shaft of the point indicating contact 1 moves. The interval between the sounds of the pen pressure sound generating section 9 changes depending on the strength of the pressing force when approaching each magnetic detection sensor section 6.

This situation is shown in FIG.

〔Effect of the invention〕

As explained above, according to the present invention, the strength of the force applied when the touch panel surface of the tablet unit is touched with the coordinate indicating pen is detected in relation to the operation of a tablet device in which coordinates are indicated with a coordinate indicating pen and points are inputted with a switch. It allows you to express the gradual strength of pressure when using a pen,
It is now possible to detect and input pen pressure, which cannot be input by simply turning on and off a switch, and to also display the pen pressure in a light-emitting display or generate a sound.

In particular, while operating the pen and instructing coordinates, it also detects the pressure of the pen at the same time, making it possible to display a light emitting display or generate sound. This has the effect of making it easier to input data while looking at it.
