The operation stick 2B, the second clutch body 35, the operation body 20, and the interlocking member 10B shown in FIG. 6 that are interlocked with the interlocking member 24 cannot be rotated either.
When the force for pulling the puller P2 shown in FIG. 3 is large and the torque applied to the connecting pipe 11B integrated with the puller P2 and the first clutch body 34 of the clutch mechanism J2 is large, the second clutch body 35 is the compression coil spring 36. Since it moves to the left against the urging force of, the puller P2 integrated with the first clutch body 34 and the first clutch body 34 slips, and the clutch mechanism J2 cuts off the transmission of the rotational force.
Further, the clutch mechanism J3 shown in FIG. 3 operates in the same manner as the clutch mechanism J2.

With the clutch mechanisms J1 to J3 provided in each stage of the drawers H1 to H3 having the above configuration, the pullers P1 to P3 of the drawers H1 to H3 are pulled excessively in the all-locked state in the locked state L of the electronic lock B. Even if a load is applied, the pullers P1 to P3 idle, so that the linkage mechanism including the interlocking operation unit F (the operation rod rotation prevention mechanism E and the operation rod rotation prevention linkage mechanism G) can be prevented from being damaged. The reliability of the all-lock device A is improved.

<Operation of mechanical locks placed side by side with electronic locks>
When the electronic lock B shown in FIG. 4 is locked, when the actuator M cannot be energized due to a dead battery or the like.
The lock piece 4 can be moved to the unlocked state by using the mechanical lock K.
That is, in FIG. 4, when the key is inserted into the keyhole of the mechanical lock K and the mechanical lock K is rotated in the unlocked state, the dead bolt 41 rises and pushes the inclined surface 28C of the connecting body 28, so that the lock piece 4 is released. It moves to the left and becomes the same unlocked state UL as in FIG.

<Effects of all-lock drawers in cabinets>
As described above, the latch devices L1 to L3 for preventing the drawers of the upper and lower multiple stages (for example, the drawers H1 to H3 of the upper and lower three stages) housed in the cabinet body O from popping out, and the electronic lock B on one of the drawers H1. In the cabinet 1 provided with the above, the all-lock device A that collectively locks the drawers H1 to H3 of all stages rotates around the axis in the left-right direction in the latch devices L1 to L3 of the drawers of each stage. The rotation of the cabinet body O is configured by a linking mechanism (operating rod rotation blocking mechanism E and operating rod rotation blocking linking mechanism G) including an interlocking operation unit F located inside the side plate 37 of the cabinet body O.
As a result, as in the case of an all-lock device using an interlocking mechanism configured between the end plates of drawers adjacent to each other as in Patent Document 1, the upper and lower drawers are displaced in the front-rear direction . Unlike the one in which the operation of interlocking the movement of the operating portion becomes uncertain, the linking mechanism including the interlocking operating portion F located inside the side plate 37 of the cabinet body O (the operating rod rotation blocking mechanism E and the operating rod rotation). The blocking linkage mechanism G) ensures that the operation can be performed even when the vertical drawers are displaced in the front-rear direction.
Therefore, it is possible to improve the reliability of the operation for putting the drawers H1 to H3 in a plurality of stages into the all-locked state in which they are collectively locked, and the operation for putting the drawers H1 to H3 in the unlocked state in which they can be pulled out.
Further, when the lock is an electronic lock B and the actuator M operates the all-lock device A, the lock piece 4 is simply moved (for example, slide-moved) by the actuator M to bring the lock piece 4 into the all-lock state. It is possible to perform an operation and an operation for setting the unlocked state.
Therefore, the power saving of the electronic lock B can be achieved, and stable and reliable operation is possible even when the electronic lock B is battery-powered and the operating force of the actuator M is weak.

In the above description, in order to bring the latch devices L2 and L3 of the drawers H2 and H3 into the disengaged state D, the elevating rod 5 constituting the operation stick rotation prevention linkage mechanism G has been raised. The elevating rod 5 may be lowered in order to bring the latch devices L2 and L3 of the drawers H2 and H3 into the disengaged state D. In that case, the elevating rod 5 may be elastically urged upward at all times.
Further, in the above description, the case where the lock provided in one of the drawers of the cabinet is the electronic lock B has been shown, but the lock may be a mechanical lock such as a cylinder lock or a dial lock.
Further, in the above description, an example in which the power source of the electronic lock is a battery has been shown, but since power saving can be achieved by the present invention, the power source of the electronic lock is not limited to the battery. For example, it may be a power source for a commercial power source or a private power generation facility.
Furthermore, in the above description, the configuration in which the all-lock device A is provided with the clutch mechanisms J1 to J3 is shown, but the clutch mechanisms J1 to J3 are not indispensable in the all-lock device A, and the clutch mechanisms J1 to J3 are used. The movement of the pullers P1 to P3 may be directly suppressed when the lock is locked.
