Description

  The present invention relates to a backpack such as a school bag that a child bears when going to and from school, and a safety monitoring system that monitors safety when the child goes to and from school.

  In recent years, crimes targeting children have increased due to diversification of crimes. For example, damage such as being attacked by a thief or encountering kidnapping frequently occurs when parents or guardians or supervisors such as school teachers are absent from school. For these reasons, the need for safety management for children is increasing.

  2. Description of the Related Art Conventionally, there has been known an example in which a child at the time of going to and from school carries a security buzzer and, when encountering damage, sounds a buzzer to notify others of the danger. However, such a security buzzer does not operate unless the child recognizes the danger and switches on. Also, even if you detect a danger and turn on the switch and the buzzer sounds, it will have no effect if there is no helper nearby. Furthermore, if you mess around with sweet words or deceive a child with a misrepresentation such as an emergency situation in your relatives and kidnap it in a car, the child will not recognize itself as dangerous and will even try to switch on the buzzer. There is a risk of not.

  Moreover, in order to ensure safety during walking, there is an example in which an image of a camera attached to the back of the collar is confirmed on a monitor attached to the front end of the collar (see, for example, Patent Document 1). Furthermore, an example is also proposed in which a small surveillance camera is attached to the user's back or bag in a rearward direction and the captured image is viewed on a portable display unit provided at hand (see, for example, Patent Document 2). ).

  However, in the examples described in the above-mentioned patent documents, the perpetrator approaching from the back is confirmed on the monitor, and the child equipped with the camera or monitor is carried by the child at the time of going to and from school. Is extremely difficult. In addition, it cannot be expected to be effective in the case of abducted by sweet words or lie, like a security buzzer. Fortunately, even if they can escape from kidnapping, there is a problem that it is difficult for the suspects to be arrested because the child cannot remember the face, clothes, car number, etc. of the perpetrator with great fear.
