Abstract
In a mechanism for inserting and removing electronic circuit units against a shelf of an electrical device where the electronic circuit units are installed, the shelf includes a groove forming part, the electrical circuit unit includes a rotatable lever, a rotatable stopper, and a housing member, and the electrical circuit unit is locked with the shelf by rotating the lever.
Claims11
A mechanism for inserting and removing an electronic circuit unit against a shelf of an electrical device where the electronic circuit unit is installed,
- wherein the shelf includes a groove forming part,
- the electrical circuit unit includes a rotatable lever having a head end where a fixing part is provided;
- a rotatable stopper connected to the lever and having a head end where an engaging part is provided;
- and a housing member housing the lever and the stopper where an engaging surface engaging with the engaging part of the stopper is provided inside thereof,
- the electrical circuit unit is locked with the shelf by rotating the lever so as to engage the groove forming part of the shelf with the fixing part of the lever, and the engaging part of the stopper engages the engaging surface of the housing member such that the engagement between the engaging surface of the housing member and the engaging part of the stopper is not released even if a force to release the fixing part of the lever from the groove forming part of the shelf is applied to the lever.

- wherein the shelf includes a groove forming part,
- the electronic circuit unit includes a rotatable lever having a head end where a fixing part is provided;
- a rotatable stopper connected to the lever and having a head end where an engaging part is provided;
- and
- a housing member housing the lever and the stopper where a projection part fixing an insertion guide surface where the engaging part is guided to the stopper by rotating the lever is provided inside thererof, and
- if a designated force is applied to the lever, the lever is rotated and the fixing part of the lever is engaged with the groove forming part of the shelf, and fixing of the stopper by the projection part of the housing member is lifted so that the engaging part of the stopper comes in contact with the insertion guide surface.
