Description

  The present invention relates to a school bag.

  In the era of rapid development of information and communication technologies, the promotion of information utilization skills in elementary and junior high schools and other educational sites was promoted more than before, which was included in the recently announced revised study guidelines. This kind of information education at elementary and junior high schools has traditionally been performed using a stationary desktop computer installed in a dedicated classroom, but in recent years, as a tool, it is highly portable and can be used anywhere. Tablet-type terminals are being replaced by stationary computers. Under these circumstances, it is almost time for elementary school students to have one tablet-type terminal and carry it with school bags together with textbooks. However, the tablet-type terminal is a precision machine that is weak against external forces such as compression and impact. On the other hand, it cannot be expected that elementary school students will pay much attention to the handling of school bags just because such precision machines are inside. Therefore, it is necessary to add to the school bag a function that can be safely transported so as not to cause failure and damage to the tablet terminal.

  In view of this, Patent Document 1 proposes a school bag including a protective storage unit for storing a protection-necessary article that requires protection from an external force, such as a tablet terminal. This protective storage part has a suede surface on the inner peripheral surface for making it difficult to damage stored articles requiring protection due to impact or the like, and the main storage in the main storage part which is the storage part with the largest volume of the school bag. It is arranged at the position on the back support part side constituting the rear wall part of the part, or at the position outside the main storage part and opposite to the back support part across the main storage part.

  However, when not carrying the backpack, the school bag is placed on the floor surface or the ground so that the front side opposite to the backrest portion or the backrest portion in the closed state is on the lower side (hereinafter, this state is referred to as “the state”). In many cases, the protective storage unit is placed in the back side of the main storage unit or on the front side of the main body of the school bag. The storage unit is disposed at a position closest to the bottom side or a position closest to the upper side. This makes it necessary for the articles requiring protection stored in the protective storage section to be easily squeezed underneath other school bags and other items, or to be subject to external forces such as pressure and impact from above. Since the protection article may be damaged, the above-described position is not a preferable storage position for the protection storage portion that stores the protection object required.
