Claims

[Claims for Utility Model Registration] 1. Notches 22a and 23 provided in the protruding walls 22 and 23 that define the front opening of the unit frame 21
A retaining device 28 for the electronic circuit package 24 inserted into the unit frame 21 through a, the proximal end being fixed to the electronic circuit package 24 so as to be able to pass through the opening of the unit frame 21. A leaf spring 29 that has a portion 29a and a tip portion 29d that can come into contact with the inner wall surface of at least one protruding wall 22 of the unit frame 21, and the tip portion 29d side can be flexibly deformed toward the opening side of the unit frame 21. Then, attach the tip end 29d side of the leaf spring 29 to the unit frame 2.
A lever 31 for releasing the retaining lever 31 whose one end is attached to the distal end portion 29d of the leaf spring 29 in order to bend and deform it toward the opening of the leaf spring 29; A device for preventing removal of an electronic circuit package, comprising: a block 30 for regulating the electronic circuit package; 2 The base end portion 29a of the leaf spring 29 is connected to the block 30.
The device for preventing the electronic circuit package from coming off as set forth in claim 1, wherein the device is attached to the device. 3. The electronic circuit package retaining device according to claim 1, wherein the lever 31 has a substantially U-shaped portion 31b on which the operator's finger is placed.
