  In the structure of Patent Document 1, the handle and the locking device are incorporated in the unit case in advance, but the operating shaft for driving the latch is attached to the back surface of the door, and then the back surface of the door so as to intersect the unit case. It was necessary to install it in the vicinity so that it could rotate. Further, since the unit case is composed of a case main body and a back cover, it is necessary to remove the back cover when assembling the operating shaft, and the assembly is complicated. For product management, the door body with a hardware mechanism and the unit case with a delicate locking device with different manufacturing processes are managed separately, and only the unit case is attached to the door body at the time of shipment. Is ideal, but because it has a structure in which the latch and the operating shaft are assembled last, ideal product management is not possible.

  Moreover, although the thing of patent document 2 is also integrated into a casing in addition to a handle and a locking tool to a latch, and the mechanism part is also unitized completely, only one latch can be provided in a latch. Like a large door or a front plate, it cannot be used to provide latches at the upper and lower ends of the door and the left and right ends of the front plate.

  Moreover, although what was described in patent document 3 pushes in the operation part to release the latch, the door can be opened to the front by pulling the finger hook part provided inside the operation window. The operation unit needs to be pushed by the finger joint to maintain the latch in the released state, but when the finger joint moves, the operation unit also moves forward when the finger joint moves, and the latch moves to the cabinet body. Since it is displaced in the engaging direction, it is assumed that the latch is engaged again and the door cannot be opened. Moreover, since the concave part can be normally closed with the lid plates on both sides, the one described in Patent Document 4 is excellent in appearance, and the door or the like can be used as a finger-hanging portion in front of either lid plate. Although it can be pulled, it is not linked to the latch.

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that an opening / closing operation unit in which a handle and an electronic lock are integrated is attached to the back surface of an opening / closing plate formed of a door of a storage furniture such as a cabinet or a drawer front plate.
