The prohibition is determined as described in the flowchart of FIG.

FIG. 6 is a block diagram of the portable detecting means 4 according to another embodiment, in which the portable detecting means 4 is constituted by an acceleration sensor 201 and a 5-minute timer 202 which are formed by adhering a heavy metal weight to a piezoelectric element. It is configured.

An individual wears the electronic timepiece 1 with the authentication function on his wrist, and the acceleration sensor 201 detects the movement while the wristwatch is moving, and the detection signal is input to the reset terminal R of the 5-minute timer 202 to output the second signal. It is a flyback signal that is input to the CU, resets the 5-minute timer 202 that had been started and integrated, and restarts. Repeat this while moving, and always restart the measurement for 5 minutes.

When an individual removes the electronic timepiece 1 with the authentication function from his wrist and leaves it for a while, the acceleration sensor 201 does not detect any movement, no detection signal is output, and there is no flyback signal.
When stationary for more than 5 minutes, the start signal was added by the second signal.
The minute timer 202 has timed out, and the time-up signal is
Output from UT. The time-up signal of 5 minutes becomes the non-portable detection signal of the portable detection means 4. The 5-minute timer 202 measures 5 minutes, but this value can be selected arbitrarily according to the purpose.

The acceleration sensor 201 does not always have to be used at the same time as the 5-minute timer 202, and the portable detection means 4 may be configured independently. The acceleration sensor 201 may be a system that does not use a weight for the piezoelectric element.

FIG. 7 is a principle view in the case of using the inclination sensor 301 instead of the acceleration sensor 201 in still another embodiment. 3 metal balls inside the tilt sensor 301
02 is put in and is set to move. Tilt sensor 30
An electrode pair 303 is fixed to the lower part of 1.

When there is movement of the arm, a metal ball 30
Due to 2, the electrode pair 303 is sometimes conductive or non-conductive. The change between conduction and non-conduction is output as the flyback signal.

When the individual removes the electronic timepiece with authentication function 1 from his wrist and leaves it, the metallic ball 302 stops, and the electrode pair 3
Either 03 remains conducting or remains non-conducting, no change and no flyback signal from tilt sensor 301. When stationary for more than 5 minutes, the 5-minute timer 202, which had been started by the second signal, timed up,
Output the time-up signal. The time-up signal of 5 minutes becomes the non-portable detection signal of the portable detection means 4.

The tilt sensor 301 is not always a 5-minute timer
It is not always necessary to use it simultaneously with 202, and the mobile detection means 4 may be configured independently.

FIGS. 8 and 9 show another embodiment of the portable detecting means 4, which is a resistance detecting means for measuring an electric resistance. 8A is a view of the case 311 of the wristwatch as seen from the side, and FIG. 8B is a view of the case 311 of the wristwatch as seen from the back.
Insulating convex parts 313 are provided in pairs on the back cover 312, and on top of that,
A pair of conductive flat electrodes 314 is provided.

When the wristwatch is not worn on the wrist, the case
The back cover 312 of 311 is contactless to the human body and has a pair of flat electrodes 31
The resistance between 4 is as high as 10 to 100 MΩ, and it is almost in an insulating state. When you put the watch on your wrist, the back cover 312 of the case 311
Is in contact with the human body, and the resistance between the pair of flat electrodes 314 is low.

FIG. 9A shows the measurement of resistance when not attached to the arm, and FIG. 9B shows the measurement of resistance when attached to the arm. The power supply 11 is a DC power supply and measures the voltages V1 and V2 across the detection resistor R1. Figure 9
In (A), the resistance value between the pair of flat electrodes 314 is R2, which is a high resistance close to insulation. In Fig. 9 (B), the resistance value between the pair of flat electrodes 314 is determined by the surface resistance of the human body at R3. When R2> R3, the voltage V1 and V2 across detection resistor R1 are V1 <V2. That is, voltage measurement detects whether the watch is carried or not.

FIG. 10 shows another embodiment of the portable detecting means 4, which is a resistance detecting means for measuring an electric resistance, and in FIG. 8, the back cover 312 is made of a metal conductive material. Figure 10
Here is an example of an insulating back cover 315 made of plastic, ceramic, or the like.

In this case, on the insulating back cover 315,
Direct convex electrodes 316 are provided in pairs. Similar to FIG. 8, resistance measurement, that is, voltage measurement detects whether the watch is carried or not. Although the insulating back cover 315 is slightly inferior in strength to metal, it has a cost advantage, a simple structure, and high reliability.

8 and 10, the electrodes are provided in a convex shape higher than the back cover 312 and the insulating back cover 315 toward the arm side of the human body, so that it is easy to touch the surface of the arm and is excellent as the portable detection means 4.

FIG. 11 shows another embodiment of the portable detecting means 4, which is a capacitance detecting means for measuring the electrostatic capacitance. The electrode for measurement has the same structure as in FIGS. 8 and 10, and is composed of a pair of electrodes. In FIG. 11, as an example of the flat electrode 314,
FIG. 11 (A) shows the measurement of the capacity when not attached to the arm, and FIG. 11 (B) shows the measurement of the capacity when attached to the arm. An AC power supply is used as the detection power supply 317 instead of the DC power supply 11. As in FIG. 9, the detection resistor R1 is used.

In FIG. 11A, the capacitance value between the pair of flat electrodes 314 is C1, which is a very small value due to the dielectric constant of air.
In FIG. 11 (B), the capacitance value between the pair of flat electrodes 314 is C2, which is determined by the dielectric constant of the human body surface. When C1 <C2, the impedance of (A) R1 + 1 / (ωC1) and the impedance of (B)
Comparing with R1 + 1 / (ωC2), R1 + 1 / (ωC1)>
R1 + 1 / (ωC2), and (B) has lower impedance.

AC voltages V3 and V4 across the detection resistor R1 are V3 <V
The value becomes 4, and the carrying or non-carrying of the watch is detected by measuring the capacity, that is, the voltage.

In the embodiment, the method of detecting resistance by using the DC power supply and the example of electrostatic detection by using the AC power supply are separately described.
The same clock can be used to improve accuracy by using both detection methods.

Although an example using a pair of electrodes has been described in the embodiment, it is possible to improve accuracy by measuring a plurality of places with three electrodes, four electrodes or five electrodes with the same watch. You can also

The same elements as those in the block diagram of FIG. 5 are designated by the same reference numerals, and the description thereof will be omitted. In Figure 12,
A sampling means 401 is newly added. Regarding the portable detection means 4, an acceleration sensor, an inclination sensor,
Although resistance detection and capacitance detection have been described, power consumption becomes a problem in a device such as a wrist watch that uses a small power source as an energy source, and a low power system is desirable.

The sampling means 401 does not always operate the portable detection means 4, but intermittently operates it only at a certain timing. For example, once every 10 seconds, the portable detection means 4 is operated for 1 second.
Activate 4 to save energy.

FIG. 13A is a waveform diagram showing continuous operation, and FIG.
(B) is a waveform chart showing intermittent operation.
Represents continuous operation for more than 2 seconds, (B) 0 ~ 1 second, 10 ~ 11 seconds,
It shows intermittent operation for 20 to 21 seconds. In simple comparison, the power consumption is 1/10 and the effect is great.

Since the portable detecting means 4 depends on the movement of the person, the wearing method of the watch, etc., accurate detection cannot always be performed. In the next embodiment, the number of times of non-carrying is counted and a non-carrying confirmation signal is output to improve the detection accuracy.

FIG. 14 is a block diagram of an electronic watch 1 with an authentication function according to another embodiment of the present invention. The same elements as those in the block diagram of FIG. 12 are designated by the same reference numerals, and description thereof will be omitted. In FIG. 14, counting means 402 is further added. In FIG. 14, non-carrying is counted a plurality of times, and the non-carrying confirmation signal is output for the first time.

Means 4, counting means 402, constant time width pulse generating means 403, AND gate 404, AND gate
It is composed of 405.

Input to reset terminal R.

On the contrary, in the case of non-carrying, from the carrying detecting means 4,
Non-portable pulse is output and pulse generation means 40
Those within a fixed time width pulse from 3 are input to the input terminal CU of the counting means 402. The counting means 402 integrates the non-portable pulse over a fixed time width, and when there is no portable pulse, completes counting a certain number and outputs a non-portable determination signal from the output terminal OUT.

FIG. 16 is a waveform diagram in which this non-carrying confirmation signal is output. This is an example of counting three non-carrying pulses.
16A is a waveform diagram of the timing signal from the sampling means 401, FIG. 16B is a waveform diagram of a portable pulse, FIG. 16C is a waveform diagram of a non-portable pulse, and FIG. 16D is constant. It is a wave form diagram of a time width pulse. FIG. 16 (E) is a waveform diagram of the non-portable signal, in which the third non-portable pulse is counted and output.

In the embodiment, the third non-carrying pulse is counted and the non-carrying confirmation signal is output.
2 can be set to any value more than once.

In the embodiment, the non-carrying pulse is output when not carried, but conversely, there is a case where the user does not want to lose the input data when the wristwatch is removed and the hand is washed. In this case, a method of operating the external operation member 6 of the electronic timepiece with authentication function 1 and not detecting that the wristwatch is removed is also very effective. Further, even if it is detected, the use of the device 58 may not be prohibited.

That is, the electronic timepiece with authentication function 1 is more convenient if the use of the device is not prohibited when the external operation member 6 is operated.

Although the number of times the device 58 is used has not been described in the above embodiments, in order to improve the reliability of management, when the user is away from the personal computer 56, the reuse is prohibited or the door of the room once opened. It may be better not to reopen 57. Hereinafter, the number of times the device 58 is used is a completely different story from the number of non-portable pulses.

The electronic timepiece with authentication function 1 is provided with a usage count measuring means for measuring the usage count of the device 58, and once used, once the usage is finished, the usage count is measured until the reading means 2 rereads. When there is a count value of the means, the prohibition measure is taken.

The authentication system is configured to prohibit the use of the device 58.

The hand-held detecting means 4 uses an optical sensor on the back side of the timepiece, and measures the difference between the brightness of the back side which is darkened by being shielded by the arm at the time of wearing and the brightness of the back side which is bright when the timepiece is removed. A method using an optical sensor for detecting and detecting mobile or non-mobile may be used.
