機体。 Figure 1 is a schematic diagram of the locking mechanism of the present invention;
The figure is an external perspective view of an image forming apparatus to which the present invention is applied, and FIG. 3 is an explanatory diagram of the operation of the locking mechanism of the present invention.
a is the open state of the upper fuselage, b is the state where the upper fuselage is closed due to "twisting" or "distortion", c is the state where the upper fuselage is further pushed down from b, d
Figure 4 shows the state in which the upper body is further closed from c, e shows the state in which the upper body is completely closed and locked, Figure 4 is an enlarged view of the main part of the state in Figure 3 d, Figure 5 The figure is a schematic side view of an image forming apparatus having a conventional locking mechanism, and FIG. 6 is a cross-sectional view of the structure of the conventional locking mechanism, in which a shows the upper body in an open state, b shows a locked state, and c shows a locked state. FIG. 3 is a diagram showing a state in which the 3... Locking mechanism, 4R, 4L... Locked piece, 5

Claims

[Claims for Utility Model Registration] Used for equipment having a first body and a second body, the first body being able to be opened and closed with respect to the second body around a support shaft. , in a locking mechanism that locks the first body and the second body when the two bodies are closed, two pieces to be locked provided on one body and the second piece provided on the other body; two locking pieces that lock each of the two locking pieces; a reverse interlocking member that moves the two locking pieces in synchronization in opposite directions; A locking mechanism characterized by having a biasing mechanism that biases toward a locking position with a locked piece.
