In a chassis connection apparatus and a chassis formed by using it, a front operation block fixed to a housing by means of a claw-shaped lock mechanism is connected to a chassis frame with a main circuit installed thereon at the back of the front operation block. The chassis can be taken out of the housing by merely pulling the chassis frame backward and releasing a claw-shaped lock. In the construction described above, an engagement section is disposed in a section where the chassis connection apparatus is connected to the chassis frame, so that the chassis frame can be connected at a later time.

Chassis apparatus

A component with an unlock mechanism is unlockably locked with respect to another component by a resilient snap tooth engaging in a hole defined in the other component. To unlock the components from each other, the unlock mechanism is pulled between the components to force the snap tooth out of the hole against its resiliency. The unlock mechanism has a slant surface that slides against a slant surface of the snap tooth to displace the snap tooth out of the hole in response to the movement of the unlock mechanism.
