When using a container with a manual pump in which the container and the manual pump are integrated and the disinfectant solution is stored inside, it is necessary to transfer the disinfectant solution in this container to the dedicated container for the automatic liquid discharge device, There is a risk that the disinfecting liquid will be contaminated during this transfer, and since the liquid ejecting part of the automatic liquid ejecting device is not disposable for each container, there is also a risk of being contaminated.

In order to solve the above-mentioned problems, the automatic liquid ejection assisting device according to the present invention has a built-in detector for detecting a human hand and the like, and the operating part of a manual pump container is pushed down to make the container It is configured by incorporating a drive mechanism that discharges the liquid inside to the outside, and even if you do not touch the manual pump of the container with a manual pump by hand, just put your hand into the detection area of this detector The liquid can be discharged to the outside, and the liquid discharge part of the container with a manual pump is disposable for each container, eliminating the need to transfer the liquid in the container to a dedicated container, which is hygienic and there is no risk of contamination. A first object of the present invention is to provide an automatic liquid ejection auxiliary device with reduced performance. A second object of the automatic liquid ejection auxiliary device according to the present invention is to provide an automatic liquid ejection auxiliary device having a drive source which can be driven by a foot switch and which is excellent in operability.

Also, in the automatic liquid discharge assisting device according to the present invention, the manual pump operating part pressing mechanism part and the power source part are slidably fitted to each other so that the manual pump operating part pressing mechanism part and the power source part can be moved to each other. In addition, the container holding portion with a manual pump is composed of an upper belt and a lower belt, and the upper belt is fitted in a groove portion of a guide rail provided in the apparatus main body so as to be vertically movable by a predetermined amount. Together with the fixing device of FIG. 2, it is movable in the vertical direction by a predetermined amount, and further, the upper belt is engaged with the first fixing device and locked by a stopper or the like, and the lower belt is fixed to the second fixing device provided on the main body of the apparatus. A third object is to engage with a tool and lock it with a stopper or the like to fix the apparatus main body to a container with a manual pump in an extremely stable state and to cope with various containers with a manual pump. .
