The first slider 91 and the second slider 94 provided on the outer sides of the first body 71 and the second body 74 are connected to the first body 71 and the second body 74, There is an effect that the fastening body 75 can be separated from the stopper 611 at a desired time.

It is assumed that the position of the coupling part 7 is out of the set position in a state where the operation part 9 is provided with only one slider. In this case, when the transfer unit 95 is moved in the direction away from the loading port 111 by the holder H, the operation unit 9 provided as one slider can move the first body 71 The second body 74 may be pressurized, or a problem may occur that the first body 71 or the second body 74 can not be pressed.

However, if the operating portion 9 is provided with the first slider and the second slider spaced from each other to provide a space for accommodating the first body 71 and the second body 74, The time point at which it is separated from the stopper 611 can be kept constant. The first slider 91 and the second slider 94 are means for minimizing a range in which the first body 71 and the second body 74 are displaced from the predetermined positions. The deviation of the time at which any one of the bodies 71 and 74 is contacted will be minimized.

Accordingly, when the door 16 moves in the direction of closing the loading port 111, the free end of the lock body extension 923 contacts the door 16. When the lock body extension portion 923 contacts the door 16, the lock body 921 moves toward the upper surface 61 of the housing 6 and the lock body 921 moves in the height direction of the housing Y-axis direction), the slider coupling portion 927 will be separated from the lock receiving groove 941. [

The lock body extension portion 923 may be inclined toward the direction away from the input port 111. [ It is possible to prevent the lock body extension portion 923 from being damaged when the door 16 is in contact with the lock body extension portion 923 and also to prevent the lock body extension portion 923 from being damaged by the lower second through hole 622, So that it can be easily moved in the direction of the arrow.

Since the space between the conveying portion 95 and the front surface 63 of the housing is narrow, the operating portion L is provided to be operated by the closing surface 167 rather than the holder H Lt; / RTI >

In addition, in order for the operating portion lock L to be operated by the protrusion 53 of the holder H, the shape of the protrusion 53 is such that the slider locking portion 927 is completely drawn out from the lock receiving groove 941 So that the lock body 921 can be moved. However, it is difficult to increase the height of the protrusions 53, and it is difficult to increase the height of the protrusions 53, considering that the protrusions 53 can be coupled to the transfer part 95 only when the protrusions 53 are inserted into the cabinet 1. [ The length in which the slider coupling portion 927 is separated from the lock receiving groove 941 should be shortened. It is more preferable that the operating portion lock L is provided to be operated by the closing surface 167 rather than the holder H, because it may cause a problem of weakening the engagement force between the operating portion lock and the slider.
