<Function> If you want to receive a call by vibration instead of sound, by setting this additional alarm device, the current flowing through the pager's current circuit changes when a call signal is received, and the current detection circuit detects this current. Detect changes. This detection signal is sent to the control circuit, and the control circuit interrupts the cutoff circuit to stop the pager from ringing, and also drives the vibration generator to generate vibration.

<Example> ゛Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a block diagram of an additional notification device for a pager. Reference numeral 1 denotes a known pager circuit that notifies by sound, and is configured to activate a speaker 2 to emit a sound when receiving a radio signal of a specific frequency transmitted from a transmitting station, and a sound to stop the notification sound. A stop switch 3 is provided.

A pager having such a pager circuit 1 is housed in a case 4 as shown in FIGS. 2 and 3,
Generally, it operates using a Fusan-type dry cell battery as a power source, but an additional alarm device is inserted into the space that houses this battery, and power is supplied to the pager circuit 1 from a small battery (for example, a button battery) contained in the device. and is connected to the battery terminal 21.

The additional notification device includes a current detection circuit 11 that detects a current flowing through a power supply circuit 20 for supplying power to the pager 1.
, a cutoff circuit 12 that cuts off the power supply circuit 20, a control circuit 15 that inputs the detection signal 13 output from the current detection circuit 11 and controls the operation of the cutoff circuit 12 and the vibration generator 16;
Small battery 13, vibration stop switch 14, and timer 22
It consists of

The current detection circuit 11 detects the power supply circuit 20 when the pager circuit 1 receives a transmission signal and activates the speaker 2.
For example, a well-known current detection circuit using an operational amplifier can be used.
Amplifies slight changes in current and outputs it as a voltage signal.

The cutoff circuit 12 is connected to the power supply circuit 20 and the control circuit 15
A circuit that interrupts the power supply circuit 20 according to a command signal from the
It consists of transistor switching circuits, etc.

The control circuit 15 is connected to the circuit of the small battery 13 via the vibration stop switch 14, and when a detection signal of a current increased by a certain level or more is input from the current detection circuit 11, the control circuit 15 is connected to the circuit of the small battery 13.
2 is cut off, and a drive current is applied to the vibration generator 16 to operate it. The timer 22 is connected to the control circuit to count the time the vibration generator 16 is activated, and the maximum activation time of the vibration generator 16 is set.

As shown in FIGS. 2 and 3, the vibration generator 16 includes a small motor 17, a disc 18 that is attached to the rotating shaft of the small motor and has an eccentric weight, and surrounds the small motor 17, the rotating shaft, and the disc 18. By rotating a disc 18 with an eccentric weight,
The entire device including the small motor 17 is vibrated, and the vibration is transmitted to the vibration transmission section 19. The rubber vibration transmitting part 19 is mostly housed inside the case 4, but its negative side protrudes outside the case 4 and has a structure in which it comes into contact with the user and transmits vibrations.

The additional notification device configured in this way is installed by being inserted into the battery space provided in the case 4 of the pager, and is attached to the battery terminal 2 provided on the pager body side.
The terminals of this device are connected to 1 as shown in FIG.

Next, the operation of the additional notification device will be described. First, when a call is made and it is desired to be notified by photographing, the switch 14 is turned on. When a paging signal is transmitted at a specific frequency from a pager transmitting station, the paging signal is received by the pager circuit 1, and the circuit 1 operates to activate the speaker 2. Then, the current flowing through the power supply circuit 20 increases due to the operation of the speaker 2, this current is detected by the current detection circuit 11, and a high-level voltage signal is output to the control circuit 15.

When the control signal 15 is input, the cutoff circuit 12
The power supply circuit 20 is cut off by outputting a cutoff signal to the pager circuit 1, and the power to the pager circuit 1 is turned off.
does not sound. At the same time, the control circuit 15 also controls the vibration generator 1.
The small motor 17 of No. 6 is driven, and the small motor 17 rotationally drives a disc 18 with an eccentric weight. As a result, an image is generated, and this image is transmitted to the user via the rubber image transmitter 19. Also, at this time, the timer 22 starts counting.

When the user recognizes the call by the vibration of the vibration generator 16, the user turns off the vibration stop switch 14, thereby stopping the vibration generator 16 and turning off the sound stop switch 3 at the same time. On the other hand, if vibration is generated and the vibration is not stopped even after a certain period of time has elapsed, the timer 22 performs a time-limited operation, the control circuit 15 stops the operation of the vibration generator 16, and returns the cut-off circuit 12 to the on state. works. As a result, the pager circuit 1 is activated again, the speaker 2 is sounded, and the notification is switched to sound, and the user can recognize the call even in a state where the user cannot recognize the call by vibration by switching to the sound.

In this way, when a pager receives a call signal, the user is first notified of the call by vibration, so even if there is a visitor and they are in the middle of an important conversation,
You won't be interrupted by a ringtone. If the pager is placed in a bag or the like and the user is not notified of a call by vibration, the pager automatically switches to the speaker and makes a sound, allowing the user to recognize the call.

Note that calling by sound can be stopped by turning off the sound stop switch 3, and calling by vibration can be stopped by turning off the vibration stop switch 14. If you want to receive a call by sound, turn off the vibration stop switch 14. Turn off.

<Effects of the Invention> As explained above, the additional notification device for a pager of the present invention can be easily installed and used in the battery space of a ready-made pager that calls by sound, and can be used in a ready-made pocket bell. A vibration calling function can be added to the pager without changing the bell circuitry at all.

Therefore, if you have something important to say and it is better not to be called by sound, you can switch to calling by vibration, and if it is better to be called by sound, you can switch one pager to do so. can be used.
