The advantages of a non-tethered stylus are obvious. That is, the behavior of the operator is restricted. This is something that never happens. However, the signal generating stylus device has an onboard power supply. I need. Traditional stylus devices use one or more storage batteries. I was using it as an onboard power supply, but I was unable to control the stylus action for a specified long time.

Embodiments of the invention A schematic diagram of a cordless electronic stylus according to the present invention is shown in FIG. The stylus is transmitter/oscillator circuit 12, constant current source 14, and one or more capacitors 16 and a resistor 18. include. The transmission activation switch 20 is provided on the tip of the stylus. constant current source 1 to transmitter/oscillator circuit 12 when the chip of the base is pressed against the working surface. It is used to connect 4. Each capacitor 16 is made of electrically insulating material. A conductive metal ring, preferably isolated and placed near the tip of the stylus. It is connected to the contact 22. By means of the DC voltage supplied to the conductive contacts 22.24 , the capacitor 16 is charged.

Switch 20 is preferably a spring loaded normally open switch. This switch is , transmitted to generate digital position data representing the position of the stylus on the working surface. /A type of device that uses a signal generated by an oscillator circuit (digitizer tablet) Place the tip of the stylus against the active surface of the Close when the user presses the button. As shown in detail in Figure 2, switch 2° When closed, power is supplied from the constant current source 14 to the transmitting circuit 12, thereby Transmission circuit] 2 is activated.

In the preferred embodiment, transmitter/oscillator circuit 12 operates at 1.5 volts at 1 milliamp. Requires constant voltage. Constant current source 14 preferably operates for 30 seconds. The overall size of the stylus is relatively small while retaining enough energy to It is desirable that the capacitor 16 be used in such a way that the value of the capacitor 16 can be selected.1. stomach .

For example, the general formula for the resistance/capacitance time constant is Tc-R*C. resistance 18 The value is therefore small and compact enough to pass a current of 1 milliamp. The physical size is reasonably large enough so that the capacitor can be incorporated into the main body 10. It is necessary to be able to do it. If capacitor 16 is active in transmitter/oscillator circuit 12, If you want to store energy in voltage, use a 150 ohm resistor and 1.5 volts. Therefore, a 0.2 farad capacitor is required. However, these values are not commercially available. The physical size of the capacitor makes its use in a stylus impractical. It is.

A solution to this problem is to reduce the voltage and current supplied to the transmitter/oscillator circuit 12 by Hold constant and increase the RC network charging voltage to create a larger resistance and A solution was found by allowing the use of smaller capacitors. It was. For example, use reasonable R and C values to give an action time of 30 seconds. This is solved by solving the following equation for E (charging voltage).

V t −E (e””) Here, Vt at t/RC (multiple of time constant) - capacitor voltage D-1,5 voltage is one hour (seconds, 30), and e is the natural logarithm constant of 2.71828. be. Then you get the following value: E-20V, ohms to R-20, and C-750 microfarad (t/RC- 2). Commercially available resistors and capacitors with the above values are included in the stylus body 10. It can be easily incorporated into The available power from capacitor 16 is Normal operation is limited to about 30 seconds, but if the capacitor can be easily and quickly recharged. It has been found that 30 seconds is sufficient for most effects if possible. .

The recharging action of the capacitor is performed using an electronic “Inkwell” 30 (recharging station). This is achieved by arranging. As shown in FIG. 3, the inkwell 30 is Adapts to the physical shape of the tip of the stylus in which the conductive contacts 22,24 are placed It consists of a charging well or boat 32. Well 32 is where the tip of the stylus is When inserted into the well 32, the conductive contacts 22.24 of the stylus contact the conductive contacts 22.24 of the stylus. Includes sex ring 34.36. Conductive ring 34.36 connects conductive contacts 22.24 The switch quickly recharges the capacitor 16 when the conductive ring 34, 36 contacts the conductive ring 34, It is connected to a DC power source 38 such as a storage battery or a DC power source. Therefore , the user can quickly "dip" the stylus into the well 32 to complete the writing process. During this time, it becomes possible to quickly recharge the capacitor 16.

In addition to well 32, ink well 30 holds the stylus for an extended period of time. It includes a storage slot 40 used for storage. storage slot 40 also includes a conductive ring 42,44 connected to the DC power source 38, thereby to keep the stylus fully charged. In the illustrated example, slot 4 0 is formed at an angle similar to a conventional pen holder, which allows the stylus to A portion of the slot extends from the slot 40. However, the slot 40 The body can be manufactured into a variety of different configurations including insertable horizontal slots. Ru.

The inkwell can be a stand-alone unit as shown in Figure 3, or a variety of other device configurations. It is also possible to use either of the following forms: For example, Figure 4 shows A digitizer tablet of the type described in Patent No. 4,672,154 is shown. , which converts the signal generated by the stylus into digitized position data.
