In addition, in FIG. 11, only one of the two lower leg portions 662D among the four leg portions 662 is illustrated for convenience of explanation.

Here, of the four legs 662, the upper two legs 662U have a shorter projection length than the lower two legs 662D. That is, when the support member 66 is fixed to the front surface of the front panel 611, the touch panel 61D assumes a posture inclined toward the front surface as it goes downward. Also, in this case, as shown in FIG. 6, the lower end position of the touch panel 61D is located below the lower end position of the drive substrate 61E by the height dimension D1.

The front panel cover 612 is made of a resin material, is a rectangular plate when viewed from the front, and covers the front of the front panel 611 . As shown in FIG. 4, the front panel cover 612 is provided with openings 6121 to 6124 for exposing the treatment instrument connector 61A, the power switch 61B, the plurality of operation switches 61C, and the touch panel 61D to the outside. ing.

waterproof films

6125 and 6126 correspond to waterproof films according to the present invention.

A first waterproof film 6125 is attached to the rear surface of the front panel cover 612 around an opening 6124 for exposing the touch panel 61D to the outside. The first waterproof film 6125 contacts the front surface of the second frame 663 when the front panel cover 612 is attached to the front panel 611 .
The second waterproof film 6126 is attached around the second opening 6631 on the back surface of the second frame 663, and the second frame 663 is attached to the first frame 661. At that time, it abuts against the front surface of the touch panel 61D.

According to this embodiment described above, the following effects are obtained.
In the driving device 6 according to the present embodiment, the front portion 61 constituting the front surface of the housing 60 of the driving device 6 includes a front panel 611 that supports a touch panel 61D and a driving substrate 61E, and a front side of the front panel 611. and a front panel cover 612 that covers the Here, the touch panel 61D and the drive substrate 61E are supported on the front panel 611 with the drive substrate 61E positioned on the back side of the touch panel 61D and a gap provided between them. Frame-shaped first and second

waterproof films

6125 and 6126 are provided between the front surface of the touch panel 61D and the rear surface of the front panel cover 612. As shown in FIG.
Therefore, the first and second

waterproof films

6125 and 6126 can eliminate the gap between the peripheral portion of the opening 6124 and the touch panel 61D, thereby improving waterproofness. Further, since a gap is provided between the touch panel 61D and the driving substrate 61E, even if a liquid such as a perfusate enters the inside of the housing 60 from the opening 6124, the function of the driving substrate 61E is maintained. Alternatively, the performance can be fully secured.
Therefore, according to drive device 6 according to the present embodiment, a structure can be realized in which sufficient countermeasures against water leakage into housing 60 from between touch panel 61D and housing 60 are taken.

In particular, the front panel cover 612 made of resin material and the second frame body 663 made of metal material have different coefficients of thermal expansion. Here, the space between the front panel cover 612 and the second frame 663 is not completely sealed with an adhesive or a sealing material. The film 6125 is configured to be in contact with the second frame 663 . Therefore, while maintaining the contact state between the first waterproof film 6125 attached to the front panel cover 612 and the second frame body 663, the front panel cover 612 is deformed due to the above-described difference in thermal expansion coefficient. can be prevented.

In addition, in the drive device 6 according to the present embodiment, the front panel 611 and the support member 66 are each made of a metal material and are fixed in contact with each other.
Therefore, even if the front panel 611 and the support member 66 thermally expand and contract due to temperature changes, the thermal expansion coefficients of the front panel 611 and the support member 66 are close to each other. The fixed state in which the support members 66 are in contact with each other can be stably maintained. Therefore, an unnecessary gap does not occur between the peripheral portion of the opening 6124 and the touch panel 61D, and a structure in which water leakage to the inside of the housing 60 is sufficiently prevented can be realized.

Further, in the drive device 6 according to the present embodiment, the support member 66 supports the touch panel 61D in a posture inclined toward the front as it goes downward.
Therefore, it is possible to realize a structure in which a liquid such as perfusate flowing along the front surface of the touch panel 61D flows only in a certain direction (toward the bottom surface portion 62 of the housing 60). In other words, since the drive substrate 61E is arranged on the back side of the touch panel 61D, the drive substrate 61E is not installed at the flow destination of liquid such as perfusate flowing along the front surface of the touch panel 61D. Therefore, even if the waterproof film 6125 is damaged and a liquid such as an irrigation liquid flows along the front surface of the touch panel 61D and enters the housing 60, the drive substrate 61E will not malfunction due to the liquid. occurrence can be avoided. In addition, since the gap between the lower end position of the touch panel 61D and the lower end position of the drive substrate 61E can be increased, the liquid such as the perfusate remaining at the lower end position of the touch panel 61D can flow toward the inside of the housing 60 together with the air moving toward the inside of the housing 60. Even if the liquid splashes to the side, it is possible to prevent the liquid from falling on the drive substrate 61E.

Further, in the drive device 6 according to the present embodiment, the touch panel 61D and the drive substrate 61E are supported with respect to the front panel 611 in a state in which the lower end position of the touch panel 61D is located below the lower end position of the drive substrate 61E. It is
Therefore, even if the waterproof film 6125 is damaged and the liquid such as the perfusate remaining at the lower end of the touch panel 61D scatters to the rear side together with the air flowing toward the inside of the housing 60, the liquid will not reach the drive substrate. 61E can be avoided. Further, since the lower end position of the drive substrate 61E can be positioned above the bottom surface portion 62, even if a liquid such as a perfusate enters the interior of the housing 60 and accumulates in the bottom surface portion 62, Also, the driving substrate 61E can be prevented from entering the liquid.

Further, in the driving device 6 according to the present embodiment, a pair of blocking members 6632 extending along the left and right edges of the touch panel 61D are arranged on the front surface of the touch panel 61D.
Therefore, it is possible to realize a structure in which a liquid such as perfusate flowing along the front surface of the touch panel 61D flows only in a certain direction (toward the bottom surface portion 62 of the housing 60). In other words, since the drive substrate 61E is arranged on the back side of the touch panel 61D, the drive substrate 61E is not installed at the flow destination of liquid such as perfusate flowing along the front surface of the touch panel 61D. Therefore, even if the waterproof film 6125 is damaged and a liquid such as an irrigation liquid flows along the front surface of the touch panel 61D and enters the housing 60, the drive substrate 61E will not malfunction due to the liquid. occurrence can be avoided.

In addition, a gasket 6111 is provided between the upper surface portion 64 and the front panel 611 in the driving device 6 according to the present embodiment.
Therefore, the gap between the front panel 611 and the upper surface portion 64 can be eliminated, and the waterproof property can be further improved.
