LOCKING DEVICE OF ELECTRONIC APPARATUS UNIT

PURPOSE:To facilitate the attachment and detachment of an electronic apparatus unit, to make possible a reliable holding of the unit subsequent to installation and to make it possible to cut down the cost of the unit by a method wherein part of an electronic apparatus case body is provided with a box-shaped recessed part and an electronic apparatus case body unit provided with a form with an elasticity is used. CONSTITUTION:An electronic apparatus case body main body 1 has a partially box-shaped recessed part 1a and moreover, has a recessed part 1b, with which an elastic body 2 is engaged from the recessed part 1a. A locking button 3 intrudes into a hole 1c provided in the side surface of the recessed part 1a. A power unit 4 has elastic parts 4a and the elastic parts 4a are engaged with projected parts 1d. A projected part 4b of the unit 4 is fitted into a recessed part 1e of the electronic apparatus case body. By pushing the button 3, the elastic parts 4a of the unit 4 are separated from the projected parts 1d and the unit 4 is pushed up by inclined parts 2a due to the elasticity of the elastic body 2. Thereby, the attachment and detachment of an electronic apparatus unit is easy and moreover, after the unit is installed, a reliable holding of the unit is possible and the cost of the unit can be reduced.
