[Problems to be solved by the device]

 However, in the case where the transport case A is rolled over to release the input product as described above, the handle parts Ac and Ac pivotally attached to the transport case A are rolled over until they are rotated to the upper surface side. If the product released from the transport case A is caught between the handle parts Ac and Ac, or the product contacts or collides with the handle parts Ac and Ac, the product is only damaged. Since the release of the product is hindered, it takes time to release the product put in one transport case A. Further, if the grips Ac and Ac pivotally attached to the transport case A are opened by the operator before the transport case A is overturned, it takes time and labor to supply the product to the sorting line. As a result, there is a problem that it is difficult to mechanically supply the product put in the transport case A to the next process.

In view of the above problems, the present invention releases the product thrown into the carrying case by opening the handle part pivotally attached to the carrying case with the handle opening means and then releasing the product. It is an object of the present invention to provide a device for releasing a handle of a carrying case, which can be smoothly carried out, labor saving in supply work, and efficiency can be improved.
