Abstract

PURPOSE:To announce the generation of abnormality by prohibiting the emission of an alarm sound when the distance between a watch part and an alarm part is near and an electromagnetic wave of substantial intensity comes into the alarm part, and emitting the alarm sound when the distance between both parts increases on account of generation of leaving behind or pilferage and the electromagnetic wave coming in the alarm part weakens. CONSTITUTION:A titled watch consists of a watch part 1 and an alarm part 4. The part 4 is normally held inserted in a chest pocket or the like. If the electromagnetic wave of a frequency fA is not supplied at the intensity higher than a specified level from the outside to an antenna, the potential at the point A is kept at the intermediate value between the positive and negative side of the radio wave, and an oscillation circuit 17 oscillates at a frequency fB. The fB passes through a filter and emits an alarm sound through a frequency divider and a power amplifier. If the electromagnetic wave of fA is supplied at the intensity higher than a specified level to the antenna, the square wave of the frequency fA is supplied to the point A; therefore, the potential at the point A cannot be maintained at the intermediate value between the positive side and negative side of the radio wave and the circuit 15 cannot oscillate at the fB. Since the signal of the fA is blocked by a filter, no alarm sounds are produced from a speaker.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to means for preventing misplacement and theft of electronic portable watches.

In modern society, watches have become a daily necessity for most people, and because they are always carried with them, they are often misplaced or lost. Mobile watches usually cost more than a few thousand yen, with expensive ones costing more than a million yen, making them vulnerable to financial loss if lost or stolen. Despite this, until now no measures have been taken to prevent cell phones from being misplaced or stolen, other than reminding owners to be careful.

An object of the present invention is to provide a means for preventing misplacement or theft of an electronic portable watch using electronic circuit technology.

The electronic portable watch with alarm function of the present invention is composed of two completely separate devices.

The present invention will be described in detail below based on examples.

FIG. 1 is a conceptual diagram of an embodiment of an electronic portable watch with an alarm function as set forth in claim 1. 1 is a clock section, and 4 is an alarm section. 2 is a time display means, 3 is a crystal oscillator, 5 is an alarm generating means, and 6 is an electromagnetic wave. FIG. 2 is a diagram illustrating the electronic portable watch with an alarm function of this embodiment based on actual use.

7 is Kai/Hoon. The alarm part 4 is usually kept in a chest pocket. If the distance between the clock part and the alarm part is close and electromagnetic waves of sufficient strength reach the alarm part, the alarm will not sound, but if something happens such as forgetting to drop it or theft occurs, the distance between the two parts will increase and the alarm will sound. When the electromagnetic waves reaching the area become weak, an alarm sounds to alert you to the occurrence of an abnormality.

In this example, the alarm part is shaped like a pen, but it can also be shaped like a lighter, cigarette case, tie pin, etc., pendant-shaped, brooch-shaped, bracelet-shaped, etc.
It may also be in the shape of a ring.

FIG. 3 is a circuit diagram of the electromagnetic radiation device in this embodiment. 8
is an antenna, 9 is the positive side of the power supply, and IO is a crystal resonator. The frequency of the radiated electromagnetic waves is determined by the In crystal oscillator. Let this frequency be f4.

FIG. 4 shows the circuit of the alarm section in this embodiment. 11 is a resonant circuit having a resonant frequency fA. ■2 is a coupling capacitor. 13 is an amplifier circuit. 14 is a waveform shaping inverter. 15 is a resonant circuit having a resonant frequency fB.

fB and fA are different. 16 is an oscillation circuit with an oscillation frequency fB. 17 is a speaker. The filter in the figure passes fB but not fh.

When the antenna in Fig. 4 is not externally supplied with an electromagnetic wave of frequency J'A with an intensity above a certain level, the potential at point A is kept at a value between the positive and negative sides of the radio wave, The oscillation circuit No. 17 oscillates at a frequency fB. The signal Ha passes through a filter, passes through a frequency divider and power amplifier, and then emits an alarm sound from a speaker. When an electromagnetic wave of fh is supplied to the antenna with an intensity above a certain level, a rectangular wave of frequency fh is supplied to point A, so the potential of point A is set to a value between the positive and negative sides of the radio wave. If it is maintained, the oscillation circuit of 15 cannot oscillate at fB.

Since J'A's signal is blocked by a filter, no alarm sound is emitted from the speakers.

FIGS. 5 and 6 show an embodiment of an electronic portable watch with an alarm function as set forth in claim 2. 18 is a radiation section. This is exactly the opposite of the embodiment shown in FIG. 1 in that the alarm sound is emitted from the clock section and the eight electric waves are radiated from a device separate from the clock section.

! The electromagnetic radiation means shown in FIG. 3 is incorporated into the radiation section 8. The clock section also incorporates the device 1 shown in FIG.

FIGS. 7 and 8 show a portable watch with a measuring function as described in claim 3. The feature is that the alarm sound is emitted from both the alarm part and the clock part.

The device 4 shown in FIGS. 3 and 4 is incorporated in both the alarm section and the clock section, with the resonance frequencies of 1() and 1 being shifted.

As described above, the present invention can be expected to be highly effective in preventing the loss and theft of electronic mobile watches.Furthermore, in the case of the watches shown in Figures 5 and 6 and Figures 7 and 8, the alarm part can be attached to a bag. By putting it in your luggage, or letting your child carry it,
It also helps prevent bags and luggage from being misplaced or stolen, and from getting lost. As described above, the present invention plays a significant role in reducing economic and social losses.
