Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wristwatch with an incoming call notification function capable of notifying an incoming call of a portable telephone such as an analog or digital portable telephone or PHS.

[0002]

2. Description of the Related Art In recent years, the widespread use of mobile phones (hereinafter referred to as mobile phones) has caused various problems unique to mobile phones.

[0003] For example, the problem of the ring tone is one of them.

That is, a mobile phone emits a ring tone everywhere, regardless of the convenience of the receiving side. For this reason, this sudden ringing tone causes annoyance to surrounding people. In particular, attention should be paid to public places where people gather, such as trains and hospitals.

Therefore, in such a place, etiquette is to turn off the power or lower the volume so that a ringing tone does not sound.

However, if the power is turned off or the volume is turned down in this way, an important telephone call cannot be received during this time. Further, there is a possibility that a problem such as not being able to contact for a long time due to forgetting to turn on the power again or forgetting to return the volume may occur.

As a method for solving this problem, there are a method in which a mobile phone is provided with a vibration mechanism, and a method in which a mobile phone is provided with a handset having a vibration mechanism to notify an incoming call by vibration.

As shown in FIG. 6, an accessory 30 such as a doll attached to a mobile phone includes a receiving circuit and an LED.
There is a lamp which has a built-in lamp and blinks an LED lamp when a receiving circuit receives a response signal from a mobile phone.

[0009]

However, in the above-mentioned mobile phone provided with a vibration mechanism or an accessory that blinks, it is not possible to notify that the mobile phone is put in a bag or the like.

[0010] Further, in the case where the slave unit is attached, there is a problem that the slave unit is forgotten or lost when going out. In addition, there is a problem that it becomes an obstacle when not in use.

It is therefore an object of the present invention to notify an incoming call of a mobile phone by a sound other than a ring tone, to enable notification even when the mobile phone is in a bag or the like, and not to be disturbed or lost when carrying the mobile phone. Is to do so.

[0012]

In order to solve the above problems, according to the present invention, a receiving means for receiving a control channel for transmitting and receiving a control signal between a base station and a portable telephone,
A configuration is employed in which a blinking circuit triggered by a detection output of the receiving means and a light emitting element connected to the blinking circuit are incorporated in a wristwatch case.

By employing such a configuration, the receiving means detects a control channel transmitted from the portable telephone to the base station for a call signal or a transmission request. When a control channel is detected, a detection output is output to a blinking circuit. A blinking circuit blinks the light emitting element when triggered by the input. In this manner, the light emitting element built in the wrist watch is flashed to notify, so that the notification can be performed even when the mobile phone is placed in a bag or the like. And since it is usually used as a wristwatch, it does not get in the way or get lost.

At this time, according to the present invention, the receiving means includes a tuning circuit configured to connect a first antenna and a second antenna in parallel so as to be able to receive two bands, That is, a configuration including a single high-frequency amplifier circuit for amplifying the generated radio wave to a trigger level is employed.

By adopting such a configuration, it is possible to support a portable telephone using different frequency bands such as analog, digital and PHS.

In this case, according to the third aspect of the invention, by adopting a configuration in which a vibrating means and its drive circuit are incorporated in place of the blinking circuit and the light emitting element, the wristwatch can be vibrated to notify the incoming call.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show a first embodiment.

FIG. 1 shows a wristwatch with an incoming call notification function according to this embodiment.
As shown in FIG. 2 and FIG. 2, a clock unit 2 built in a wristwatch case 1 made of a translucent resin, and an incoming call notification unit 3
It consists of

The timepiece 2 is a needle type using a quartz oscillator for the movement, and is provided on the dial 5 side of the case 1 divided into two layers by the substrate 4.

In this embodiment, a needle type analog type is used for the movement. However, the present invention is not limited to this. For example, a digital type using an LCD may be used.

On the other hand, the incoming call notification unit 3 is provided on the back cover 6 side. As shown in FIG. 3, the incoming call notification unit 3 includes a receiving circuit 7 and a blinking circuit 8, and a light emitting element 9 is connected to the blinking circuit 8.

The receiving circuit 7 comprises a tuning circuit 10 and a high frequency amplifier circuit 11.

The tuning circuit 10 includes two antenna coils A
1, A2, capacitors C1 and C2, and a resistor R1, and a first antenna coil A1 is connected to a connection point where one end of each of the capacitors C1 and C2 is connected. Also, by connecting the second antenna coil A2 to the other end of the capacitor C2 and connecting it to the high-frequency amplifier circuit 11 at the subsequent stage,
Analog mobile phone using 800MHz band and 1.5
It is possible to receive digital and PHS different control channels using the GHZ band.

The two antenna coils A1 and A2 are:
For example, if formed as a strip line on the substrate 4,
Since it can be easily configured and does not use a coil, it can be downsized and is an optimal circuit to be built in a wristwatch.

As shown in FIG. 3, the high-frequency amplifier circuit 11 comprises an RC-coupled two-stage amplifier circuit using npn transistors. First stage transistor T1 of the amplifier circuit
Is a preamplifier, and the second-stage transistor T2 is an output amplifier.

The resistors R2 and R3 are connected to the transistor T
A DC bias of 1 is set, and the resistor R4 is the load resistance of the collector. Further, the resistors R5 and R6 are used to set the DC bias of the transistor T2.
And R8 are for setting the output voltage.

That is, the small signal received by the antenna coils A1 and A2 slightly changes the base current of the transistor T1. This change is amplified by the transistor T1 and, via the capacitor C4, the transistor T2
Change the base current of Therefore, the transistor T
2 changes, the change in the voltage is caused by the resistance R
The signal is input to the trigger input of the blinking circuit 8 via the switch 7.

In this embodiment, the blinking circuit 8 is a CMOS type LSI having three outputs for driving the LED and a trigger input. When a signal having a threshold level or more is input to the trigger input, the blinking circuit 8 is connected to each output. The light emitting element 9 is turned on and off for a certain period of time.

The light emitting element 9 has three LEs of red, green and yellow.
D, and is attached along the inner periphery of the case 1 as shown in FIG.

The timepiece is provided with an off switch 13 for turning off the receiving circuit when the incoming call function is not used.

The switch 13 is provided below the crown. When the switch 13 is pulled out, the receiving circuit 7 is turned off.
N so that the tip does not get in the way when hitting the arm.

As shown in FIG. 3, the switch 13 is turned off by connecting it to a trigger input of the blinking circuit 8 via a trigger circuit 14, for example.
, The flashing circuit 8 is triggered only once to trigger the light emitting element 9
Is turned on so that an OFF display and a check of battery consumption can be performed.

This embodiment is configured as described above.
This wristwatch with an incoming call notification function is worn on an arm and used as a normal wristwatch. Then, when carrying the mobile phone, the user presses the off switch 13 to turn it on. Then, the receiving circuit 7 operates and enters a standby state. In this state, the receiving circuit 7 always receives the control channel,
It is amplified and input to the blinking circuit 8.

That is, as shown in FIG. 4, when the mobile phone is called from the base station 15, it exchanges free channel information and the like using the control channel. At this time, the gain of the receiving circuit 7 is set so that the output voltage exceeds the trigger level of the blinking circuit 8 by the electric field strength of the control channel transmitted by the mobile phone (possessed) within an effective distance of about 1 m. When the output voltage exceeds the trigger level of the blinking circuit, the blinking circuit blinks the three light emitting elements 9 to notify.

Therefore, if the volume of the ringing tone is lowered, an incoming call can be notified by blinking of the light emitting element 9.

Therefore, for example, in a place where people gather, such as a train or a hospital, there is no trouble for surrounding people. In addition, there is no problem that the user cannot turn on the power for a long time by forgetting to turn on the power again or forget to return the volume.

Further, when the connection is completed and the transmission by the control channel is stopped, the detection voltage of the receiving circuit 7 drops and becomes lower than the trigger level of the blinking circuit 8, so that the blinking circuit 8 is turned off. The light emitting element 9 is turned off.

On the other hand, when a call is made from the mobile phone, the receiving circuit 7 receives the control channel transmitted from the mobile phone, triggers the blinking circuit 8, and flashes the light emitting element 9 to notify. When the connection is completed and the transmission by the control channel stops, the blinking circuit 8 is turned off and the light emitting element 9 is turned off.
Turns off.

As described above, this wristwatch with an incoming call notification function can notify the incoming and outgoing call of the mobile phone. At this time, the provision of the two antenna coils A1 and A2 allows a simple configuration to be notified regardless of analog, digital, or PHS.

Further, since the high-frequency amplifier circuit 11 is an RC-coupled two-stage amplifier circuit, the gain can be easily set so that the user can be notified even when the mobile phone is put in a bag or the like.

Furthermore, since it can be normally used as a clock, it does not get in the way or get lost.

FIG. 5 shows a second embodiment.

In this embodiment, a vibrating means 20 is used in place of the blinking circuit 8, and as shown in FIG. 5, a vibrating means 20 such as a piezoelectric element is connected to a high-frequency amplifier circuit 11 via a driver circuit 21. By the connection, when the output of the high-frequency amplifier circuit 11 exceeds the trigger level of the driver circuit 21, the vibration means 20 is turned on.

In this manner, vibration is applied to the arm from the vibrating means 20 which has been turned ON, and the incoming call can be notified only to the person.

The other configuration and other functions are the same as those of the first embodiment, and the description is omitted.

[0047]

The present invention is constructed as described above, and has an incoming call function added to a wristwatch so as to blink.
The incoming call of the mobile phone can be notified by other than the ringtone.

Further, since the notification can be made even when the mobile phone is placed in a bag or the like, the problem caused by the ring tone can be solved.

Moreover, since it is normally used as a timepiece, it can be prevented from getting in the way or being lost.
