2. Description of the Related Art Recently, an increasing number of people wear a shoulder belt of a shoulder bag through a neck. Most of these people carry a notebook personal computer, and hang their shoulder belts through their necks so that the main body of the bag slips off their shoulders and does not impact the stored notebook personal computer.
In addition, when the shoulder belt is hung through the neck, the bag body comes into closer contact with the body, and the shoulder bag body shakes, making it difficult to contact other objects. However, this type of shoulder bag has a problem in that the stored bag may still have a strong impact even if the bag itself does not fall off from the shoulder, not when the bag itself collides with other objects during walking or the like. have.

[0003] Therefore, if a backpack is used to carry this kind of precision equipment, it is said that there is almost no contact with other objects during walking, and careless impact is not applied to the stored items. . However, this type of backpack often holds a long backpack when it is dropped from the back on the floor, etc. Bags are usually vertically long, and if they are placed upright, they often fall down, and when they fall down, there is a problem that they often give a shock to stored items.

[0004] Furthermore, since the backpack is generally manufactured by sewing the entire fabric with a soft cloth material, there is a possibility that the corners of the stored items collide with the floor or the like, and the impact force is concentrated. Furthermore, when sewn with a flexible cloth, when the lid is opened, only the stored items fall down in an unpredictable state, and the stored items may receive a large impact. I have.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has the advantage that the backpack cannot easily come into contact with other objects while walking as described above, and that both hands can be freely used. Focusing on the advantage that it can be used, it is an object of the present invention to solve the problem that stored items are susceptible to impact when not carrying the above, and to provide a backpack that less impacts on stored items. .

[0006]
