When is large, it may be difficult for school children to turn the blade-proof member.
Therefore, the technical problem of the present invention is that the blade-proof member can be securely fixed to the front portion of the school bag, but if the child is involved in a magical case, the schoolchild can easily and quickly attach the blade-proof member to the body. An object of the present invention is to provide a blade-proof school bag that has a fastening means between the blade-proof member and the front portion of the school bag so that it can be turned to the use position on the front side.
Another technical problem of the present invention is that even if the blade member is swung to the front side of the body, the blade member may be peeled off later. Therefore, the blade member is swung to the front surface of the body. It is an object of the present invention to provide a blade-proof school bag in which an alarm device operates even when the alarm device is peeled off or removed later.

  In order to solve the above-described problems, the blade-proof school bag of the present invention is constructed by connecting a blade-proof member for protecting the school bag user to the upper end portion of the back plate of the school bag with an extendable connecting member. A member that is pivotable between a storage position that is fixed along the front of the school bag and a use position that covers the front of the body of the school bag user. The attachment means is constituted by a magnet attached to the blade-proof member and the front portion of the school bag, and an adsorption fitting magnetically attracted to the magnet.

In the present invention, the blade-proof member is a cover member that covers the outer surface of the cover lid, and is configured by incorporating a blade-proof plate in the cover member, or opens and closes the opening of the school bag. It may consist of a cover lid for this purpose, and may be configured by incorporating a blade-proof plate in this cover lid.
Moreover, in this invention, the said blade prevention board is a metal plate with magnetism, Comprising: It can comprise as what also serves as the said adsorption metal fitting.

In a preferred embodiment of the blade-proof school bag according to the present invention, an operating member is attached to the upper end of the blade-proof member and for turning the blade-proof member to a use position. It is desirable that the operation member is constituted by a pulling string having a tip end detachably held on a backpack of the school bag.
Further, an alarm device is attached to the school bag, and the alarm means for operating the alarm device and the blade prevention member are responsive to the turning of the blade prevention member toward the front of the body, and the alarm means alerts the body. The devices can be connected to operate.
