ととなる。2. Description of the Related Art As shown in FIG. 5, a self-standing electronic device has chassis 1 and 2 containing magnetic tapes housed in a housing 3 so as to be freely drawn out. The chassis 1 and 2 are generally provided on the upper part of the housing 3, and if the chassis 1 and 2 are pulled out at the same time, there is a risk that the housing 3 may fall down if the weight of the chassis 1 and 2 is large. To prevent this, for example, as shown in FIG. 6, support legs 4 are attached to the lower front portion of the housing 3, or a heavy load 5 is provided on the lower rear portion of the housing 3. However, when the support legs 4 are attached, not only the appearance is bad, but also the operator can
There is a risk of getting caught in the ground, and the provision of the heavy load 5 requires a large space, which is against the trend of reducing the size and weight.

Will be explained. In Figure 3, when the chassis is stored,
The convex portion 15 of the housing side locking tool 10 is in front of the square hole 21 on the chassis side locking tool 20 (cross section AA), and the convex portion 16 is in front of the square hole 26 on the chassis side locking tool 25. (Cross section BB) Contact each other. In this state, the housing-side locking tool 10 is biased in the closing direction against the force of the spring 14. Here, when only the chassis 30 is pulled out, since the chassis 31 is in the housed state, the convex portion 16 is in contact with the front of the square hole 26, and the housing side locking tool 10 is biased in the closing direction. The above state is maintained (section BB), and therefore the chassis 30 can be freely pulled out (section AA).
Next, when pulling out the chassis 31 with the chassis 30 pulled out, if the chassis 31 is slightly moved, the convex portion 16
Comes to the position of the square hole 26, but in this case, since the convex portion 15 is in a free state (cross section AA), the housing side locking tool 10 is easily opened by the reaction force of the spring 14, and the convex portion 16 is formed. Engage the square holes 26. Since the opening degrees θ (see FIG. 1) of the plate-shaped members 11 and 12 are set so as not to exceed a predetermined angle, the chassis 3 is formed by the engagement of the convex portion 16 and the square hole 26.
1 can be prevented (cross section BB).
