[Prior art]
Conventionally, for the purpose of preventing the loss or theft of a portable product, as shown in FIG. 7, a transmitter / receiver 51 that transmits a radio wave 53 of a predetermined frequency and the radio wave 53 that is attached to a portable product and that receives the radio wave 53 are received. There is a forgotten object prevention system 50 including a radio wave reflector 52 that uses the energy of 53 as a power source and transmits a reflected radio wave 54 having a frequency different from a predetermined frequency of the radio wave 53 to a transceiver 51. In the forgotten object prevention system 50, the radio wave 53 received by the radio wave reflector 52 is weakened when the distance between the transmitter / receiver 51 and the radio wave reflector 52 is increased, whereby the radio wave reflector 52 transmits the wave to the transmitter / receiver 51. When the reflected radio wave 54 is weakened or does not reach the transceiver 51, that is, the transceiver 51 possessed by the user can receive the reflected radio wave 54 from the radio wave reflector 52 attached to the portable item. When the distance away is reached, an alarm device (not shown) included in the transceiver 51 sounds a buzzer sound, thereby preventing the user from leaving the portable item behind (see, for example, Patent Document 1).

[Problems to be solved by the invention]
However, in such a forgotten object prevention system 50, if the user who owns the transmitter / receiver 51 is further away from the portable item to which the radio wave reflector 52 is attached after the alarm device once beeps, the buzzer sound However, it was not possible to judge whether the distance to the portable item with the radio wave reflector 52 was short even though it was found that the portable item was far away due to the buzzer sound. .
[0005]
In addition, the buzzer sound that warns that the transmitter / receiver 51 is separated from the radio wave reflector 52 attached to the portable product until it cannot receive the reflected radio wave 54 is transmitted to the transmitter / receiver 51 that the user has. Since the sound continues until it reaches the radio wave reflector 52 up to the receivable distance, the buzzer sounds that the mobile device is far away and the buzzer sounds more than necessary when the user further moves away from the mobile device. As a result, not only wasteful power is consumed, but in some cases, the user is uncomfortable.
