[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device carrying confirmation system for confirming whether a person entering or exiting a building or the like carries a portable terminal device.

[0002]

2. Description of the Related Art In recent years, there has been remarkable spread of portable terminal devices such as portable telephones, and these portable terminal devices have become a part of the body. However, it is often the case that one forgets to carry a portable terminal device when going out, and in such a case, the other party cannot contact the owner of the portable terminal device, and the owner of the portable terminal device also makes a telephone call. In some cases, the transmission of such information could not be carried out, causing serious problems in operations. Also, if a portable terminal device with its power turned on is brought into a specific section of a medical facility such as a hospital, the radio waves transmitted from the portable terminal device may adversely affect the medical device, and may be used in concert halls, ceremony halls, etc. If a portable terminal device with its power turned on is carried into a place where it is necessary to refrain from receiving / transmitting the portable terminal device, a great deal of trouble may be caused by the ringtone.

[0003] For this reason, it is necessary to carry a portable terminal device when going out, to carry a portable terminal device, and not to carry a portable terminal device while the power is on when entering a place where reception / transmission is prohibited. Must be surely confirmed. Conventionally, devices or systems that perform such confirmation automatically have not been put to practical use, and have had to rely on human attention and confirmation. For this reason, confirmation was sometimes omitted, and inconveniences such as unaccompaniedness when going out and carrying in a place where carrying was unreliable sometimes occurred.

[0004] In addition, when traveling by a vehicle such as an automobile, it is often necessary to forget to carry a portable terminal device when getting off the vehicle. It was neglected and others could not contact the owner of the mobile device. For this reason, it is necessary to confirm whether or not the portable terminal device has been left inside the vehicle even when getting off the vehicle. Conventionally, a device or a system for performing such confirmation automatically has not been put to practical use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a portable terminal device carrying confirmation system according to the present invention will be specifically described with reference to the drawings. As shown in FIG. 1, a human body sensor 2 and an antenna 3 are provided at a gate 1 through which a person passes.
The human body sensor 2 is connected to the amplifier 4 and the antenna 3 is connected to the receiver 5. When the human body sensor 2 detects a human body, the antenna 3 receives a radio wave transmitted from a portable terminal device such as a mobile phone from the amplifier 4. At this time, a true output is obtained from each of the receivers 5. Reference numeral 6 denotes an AND operation element, and 7 denotes a NOT operation element which receives an output of the receiver 5 as an input. The input of the AND operation element 6 includes an output of the amplifier 4 and an output of the receiver 5 selected by the switch 8. Alternatively, the output of the NOT operation element 7 is added, and the output of the AND operation element 6 is applied to the alarm element 9. The alarm element 9 issues an alarm by sound, light, or the like when the output of the AND operation element 6 becomes true.

As the human body sensor 2, a pyroelectric sensor for sensing far infrared rays, a photoelectric switch, or the like can be used.
The mobile terminal device periodically transmits radio waves of the assigned frequencies for a short period of time, but the antenna 3 is located very close to the mobile terminal device to be detected and the reception radio wave is strong. By increasing the bandwidth, radio waves from various portable terminal devices having different frequencies can be received. Further, it is also possible to install a plurality of antennas 3 and receivers 5 each covering a specific frequency band as needed. It is preferable that the antenna 3 has as narrow a directivity characteristic as possible, and it is preferable that the receiver 5 hold the output for a time corresponding to the radio wave transmission interval of the portable terminal device every time the radio wave is received once.

In the above configuration, the switch 8 is set on the side to which the output of the NOT operation element 7 is added to the input of the AND operation element 6, and when the person carrying the portable terminal device passes through the gate 1, the human body sensor 2 Detects a human body, the antenna 3 receives radio waves transmitted from the portable terminal device, and the outputs of the amplifier 4 and the receiver 5 are both true. Therefore, the output of the NOT operation element 7 becomes false, the output of the AND operation element 6 becomes false, and the alarm element 9 does not issue an alarm. Next,
When a person who does not carry a portable terminal device passes through Gate 1,
The human body sensor 2 detects the human body, the antenna 3 does not receive the radio wave transmitted from the portable terminal device, the output of the amplifier 4 is true,
The output of the receiver 5 is false. Accordingly, the output of the NOT operation element 7 becomes true, the output of the AND operation element 6 becomes true, and the alarm element 9 issues an alarm.

As a result, it is possible to warn that a person passing through the gate 1 forgets to carry the portable terminal device. Also,
Even if a person passing through the gate 1 carries the portable terminal device, the antenna 3 does not receive the radio wave transmitted by the portable terminal device when the power is not turned on, which is the same as not carrying the portable terminal device. And an alarm will be issued,
You can also give an alarm to forget to turn on the power. Here, since the antenna 3 has a narrow directional characteristic, it does not receive radio waves of portable terminal devices other than the portable terminal device carried by the person passing through the gate 1, and the portable terminal device transmits radio waves. Although this is an extremely short time, the AND operation element 6 can reliably perform the logical operation by the receiver 5 holding the output. Further, in order to prevent the antenna 3 from receiving radio waves from portable terminal devices other than the portable terminal device carried by the person passing through the gate 1, measures can be taken to appropriately arrange a shield plate or the like.

In the above-mentioned configuration, the switch 8 is set to the side to which the output of the receiver 5 is added to the input of the AND operation element 6, and when a person who does not carry the portable terminal device passes through the gate 1, the human body Sensor 2 detects the human body,
Since the antenna 3 does not receive the radio wave transmitted from the portable terminal device, the output of the amplifier 4 is true and the output of the receiver 5 is false. Therefore, the output of the AND operation element 6 becomes false, and the alarm element 9 does not issue an alarm. Next, when the person carrying the portable terminal device passes through the gate 1, the human body sensor 2 detects the human body, the antenna 3 receives the radio wave transmitted by the portable terminal device, and the outputs of the amplifier 4 and the receiver 5 are both output. Be true. Therefore, the output of the AND operation element 6 becomes true, and the alarm element 9 issues an alarm.

As a result, a warning that a person passing through the gate 1 carries a portable terminal device can be issued. Also, even if a person passing through the gate 1 carries a portable terminal device, the antenna 3 does not receive radio waves transmitted from the portable terminal device as long as the portable terminal device is not carried if the power is turned off. Therefore, the alarm element 9 does not generate an alarm.

Therefore, if the portable terminal device carrying confirmation system having the above-mentioned configuration is installed in an office, an entrance of a house, or the like, it is possible to warn that the portable terminal device is forgotten when going out and that the power is turned on. In addition, if the portable terminal device carrying confirmation system of the present invention is installed at the entrance of a specific section such as a hospital, the entrance of a concert hall, the reception of a ceremony hall, etc., the portable terminal device which is turned on at the time of entrance can be carried. An alarm can be given to bring in or to forget to turn off the power of the portable terminal device. In addition, it is possible to specify a person who intends to carry a portable terminal device that is turned on. Although the gate 1 is provided in the above embodiment, the human body sensor 2
The antenna and the antenna 3 may be appropriately provided, and there is no particular need to provide a gate.

FIG. 2 shows a case where the portable terminal device carrying confirmation system of the present invention is mounted on a vehicle. The components are the same as those shown in FIG. 1, and are denoted by the same reference numerals.
In this configuration, if the user tries to get off the vehicle with the portable terminal device placed in the vehicle, the human body sensor 2 does not detect a person, the receiver 5 receives radio waves, the output of the amplifier 4 is false, and the receiver The output of 5 is true. Therefore, the output of the AND operation element 6 becomes true, and the alarm element 9 issues an alarm. When installed in a vehicle, a seat switch can be used as the human body sensor 2.

[0015]

According to the present invention described above, there is an advantage that the presence or absence of a portable terminal device carried by a passing person can be surely confirmed. Furthermore, an alarm that alerts the user to forget to carry or turn on the portable terminal device when going out, an alarm to carry the portable terminal device that is turned on when entering, and an alarm to leave the portable terminal device inside the vehicle when getting off the vehicle Has the advantage of being able to do both.
