PROBLEM TO BE SOLVED: To provide a lock mechanism allowing simply and certainly mounting and removing a member to be locked. SOLUTION: The lock mechanism 3 includes an engaging pin (a part to be engaged) 22 provided on a parts cassette (member to be locked) 2, which is fixed to an installation table (body part) 1 by pressing an engagement part 20 provided on the installation table 1 to the pin 22 with the force of a spring 23, wherein a disengaging lever 30 is swung previously against the spring force and the shaft-supported engagement part 20 is retreated in advance, whereby the pin 22 and the engagement part 20 will never abut to each other immediately before the parts cassette 2 is fixed to the installation table 1. This facilitates fixation of the parts cassette 2, and also generation of a shock at the time of locking can be suppressed. Alike the disengaging lever 30 is used when the parts cassette 2 is to be removed from the installation table 1. |
