The waterproof and breathable member 3 is disposed on the inner surface of the back cover 12 and completely shields the heat dissipation hole 1211 (ie, the waterproof and breathable member 3 is located in the heat dissipation airflow F). Passing through the path through which the vent hole 1211 must pass). In the present embodiment, the waterproof venting member 3 is provided with two through holes 31, and the two positioning posts 1214 of the back cover 12 are respectively disposed through the two through holes 31 of the waterproof venting member 3, thereby achieving the effect of positioning the waterproof venting member 3; The display device 100 is filled in the recess 1213 through the heat-resistant colloid 2, and the heat-resistant colloid 2 is adhered to the waterproof gas permeable member 3 so that the waterproof gas permeable member 3 is adhered to the inner surface of the back cover 12 (ie, the position of the waterproof gas permeable member 3). Corresponding to the first wall 1216) of the trough body 1215. Further, the waterproof gas permeable member 3 is adhered to the region of the waterproof gas permeable member 3 in a closed region around the heat dissipation hole 1211. Therefore, when the heat dissipation airflow F flows out of the casing 1 through the heat dissipation hole 1211, the heat dissipation airflow F can only pass through the waterproof gas permeable member 3; and the waterproof gas permeable member 3 can block the outer side of the casing 1 from flowing through the heat dissipation hole 1211. Any liquid (figure omitted).

More specifically, the heat-resistant colloid 2 is exemplified in the present embodiment, that is, the heat-resistant colloid 2 has a melting point of approximately 160 ° C, and the heat-resistant colloid 2 has a heat-resistant temperature of approximately 130 ° C. The waterproof gas permeable member 3 includes a nonwoven fabric 32 and an annular reinforcing sheet 33 fixed to a portion around the nonwoven fabric 32.

Further, the waterproof gas permeable member 3 is closed by the region where the heat-resistant colloid 2 is adhered, thereby effectively preventing the liquid from entering the casing 1 through the heat dissipation hole 1211.

It should be noted that the display device 100 can have a heat dissipation speed that meets the requirements without a heat dissipation fan, but does not have an excessive influence on the heat dissipation speed of the display device 100, corresponding to the air intake hole. The casing 1 of the 1212 is preferably not provided with any waterproof gas permeable member 3, but is not limited thereto. Further, according to the usage of the point-of-sale device 1000, the liquid hardly enters the accommodating space S of the casing 1 from the air inlet 1212 at the bottom of the casing 1, and even if the liquid enters the casing 1 from the air inlet 1212. In the present embodiment, the liquid is also affected by gravity and flows along the inner surface of the casing 1 so as not to damage the electronic module 4. Therefore, the casing 1 corresponding to the air inlet 1212 is located in this embodiment, and it is not necessary to provide a waterproof and permeable member. 3.

Furthermore, when the display device 100 is not provided with the waterproof gas permeable member 3 (that is, equivalent to a conventional display device), the heat dissipation speed of the display device 100 is designed to be 100% of the operational load state, but the normal operation load of the display device 100 Usually 40~60%, up to 80%. Therefore, when the waterproof gas permeable member 3 is attached to the casing 1 corresponding to the heat dissipation hole 1211, the heat dissipation speed of the display device 100 does not affect its normal use.

In addition, the point of sale device 1000 can be adjusted according to the needs of the designer in addition to the aspects presented in FIGS. 1 and 2. For example, as shown in FIG. 7, the point of sale device 1000 may further include a screen 300 mounted on the support frame 200, and the screen 300 and the display device 100 respectively face opposite directions (such as the screen 300 in FIG. 7). Right, display device 100 is turned to the left) so that the screen 300 can be provided for viewing by the consumer.
