[Problem to be Solved] The present invention relates to rationalization of a disassembling operation of electronic devices before crushing the devices in order to achieve urban mines, and has an object to achieve mechanical disassembling without significantly destroying components containing many rare elements to be recovered. [Solution] In order to achieve the object, the invention 1 provides a casing disassembling apparatus including : a first rotor and a second rotor journaled on a rotating shaft, and having end surfaces perpendicular to the rotating shaft, wherein the end surfaces face each other, the rotors are placed so that the end surfaces are inclined to each other, a portion at which a space between the end surfaces is larger than at the other portion is an input port of an object to be disassembled, and the other portion is a portion at which a pressurizing force is applied to the input object to be disassembled, and from which a disassembled piece is ejected. The invention 2 provides the casing disassembling apparatus, wherein a plurality of protrusions are mounted to at least one of the end surfaces in the invention 1. The invention 3 provides the casing disassembling apparatus, wherein protrusions are provided on a periphery of one of the end surfaces at predetermined intervals corresponding to a size of the ejected disassembled piece in the invention 2. The invention 4 provides a disassembling method using a casing disassembling apparatus according to any one of the inventions 1 to 3, wherein a relative inclination angle and an inclination angle to the vertical of end surfaces are adjusted to set a space of an input port and a pressurizing force correspondingly to an object to be disassembled such as an electronic device. According to the present invention, a casing can be crushed without components containing rare metal being crushed to a level that the components cannot be recovered. Also, an electronic device can be mechanically disassembled so that the casing and the components can be disconnected from each other and can be separately recovered.
