Next, the operation of such an information processing apparatus will be described.
When using this information processing apparatus, the cooling fan 7 rotates to take outside air into the apparatus main body 1 from the air inlet 11 provided in the upper case 1 a of the apparatus main body 1. In this case, the intake port 11 is provided in the inclined portion 10 provided in the upper edge portion of the rear side of the upper case 1 a of the apparatus main body 1, so that outside air is taken in from the upper side on the rear side of the apparatus main body 1. .

The taken-in outside air is guided by the duct portion 13 in the apparatus main body 1 and guided to the cooling fan 7. At this time, since the duct portion 13 is a duct space formed continuously from the lower side of the intake port 11 to the upper side of the cooling fan 7, the air taken in from the intake port 11 is reliably supplied to the cooling fan 7. Can lead.

Then, when the air guided by the duct portion 13 is sent to the upper side of the cooling fan 7, it is blown downward by the cooling fan 7, and the blown air cools the component unit 8 in the apparatus main body 1, The cooled air is discharged to the outside of the apparatus main body 1 through an exhaust port 15 at the lower side surface located at a position away from the cooling fan 7 in the lower case 1 b of the apparatus main body 1. Thereby, even if the component unit 8 generates heat, the component unit 8 can be cooled satisfactorily.

In this case, in the case of a model in which the component unit 8 generates a small amount of heat, the intake range of the intake port 11 can be adjusted by the intake adjustment member 14 to adjust the intake amount according to the model. That is, as shown in FIG. 11, by moving the intake adjustment member 14 toward the cooling fan 7 in the duct portion 13, the intake range of the intake port 11 is narrowed, and the outside from the intake port 11 is Thus, the intake amount of the intake port 11 can be adjusted according to the model of the component unit 8 having a small heat generation amount.

As described above, when the intake range of the intake port 11 is narrowed by the intake adjustment member 14, the range in which the intake adjustment member 14 moves, that is, is partitioned by the intake adjustment member 14 and positioned on the side opposite to the cooling fan 7 side. Since the duct region is opened in the apparatus main body 1, a part of the intake port 11 functions as an exhaust port, so that the air that has cooled the component unit 8 can be efficiently discharged from the exhaust port 15 together with a part of the intake port 11. It can be discharged outside the apparatus body 1.

At this time, the exhaust amount can also be adjusted by adjusting the exhaust range of the exhaust port 15 by the exhaust adjusting member 16. That is, as shown in FIG. 12, when the exhaust adjustment member 16 is moved from the front side (lower side in FIG. 12) toward the rear side (upper side in FIG. 12) of the apparatus main body 1, the exhaust of the exhaust port 15 is exhausted. The range can be narrowed, so that the exhaust amount can be adjusted according to the model of the component unit 8 that generates less heat.

By the way, when the water droplet falls on the apparatus main body 1 and enters the apparatus main body 1 from the air inlet 11 during the use, the water droplets are discharged to the outside of the apparatus main body 1 through the water droplet discharge path 17. can do. That is, as shown in FIG. 13, water droplets that have entered the apparatus main body 1 from the air inlet 11 are dripped onto the flow plate 18 along the water droplet guide ribs 12, and the dropped water droplets follow the inclination of the flow plate 18. It flows toward the rear side (the left side in FIG. 13) of the upper case 1a, flows into the vertical hook portion 19, and is guided downward by the vertical hook portion 19, and the joint between the upper case 1a and the lower case 1b of the apparatus body 1 Is discharged to the outside of the apparatus main body 1 through the gap 20 provided in the apparatus.

Further, at this time, when a water droplet falls on the mounting cover 22 of the device mounting portion 6 in the apparatus main body 1 and enters the apparatus main body 1 from the periphery of the mounting cover 22, as shown in FIG. The discharged water droplets can be discharged to the outside of the apparatus main body 1 through the auxiliary water droplet discharge path 23. That is, the water droplets that have fallen on the mounting cover 22 are guided to the lower front side of the mounting cover 22 by the discharge grooves 24 provided on the lower outer periphery of the mounting cover 22.

As shown in FIG. 16, the introduced water droplets are provided on the front side surface in the upper case 1 a located on the front side of the mounting cover 22, and are directed from both sides of the front portion of the mounting cover 22 toward the middle lower portion of the mounting cover 22. Then, it is collected and dropped at the middle lower part of the mounting cover 22 by a collecting collar 25 consisting of a pair of inclined ribs 25a, 25b. The dropped water droplets are discharged to the outside of the apparatus main body 1 through a gap 27 provided at the joint between the upper case 1a and the lower case 1b of the apparatus main body 1 through the discharge passage 26.

Furthermore, when water droplets adhere to the front side of the input display device 2 mounted on the device mounting portion 6 of the apparatus body 1, that is, the front surface of the input display case 3 and the surface of the input display panel 4, the attached water droplets Intrusion into the input display case 3 can be prevented by the drip-proof packing 30. That is, water droplets adhering to the front surface of the input display case 3 and the surface of the input display panel 4 flow from the upper side to the lower side, but the drip-proof packing 30 prevents entry into the input display case 3 and 3 is dropped from the lower end of the input display case 3 through a first packing 33 provided on the lower side of the opening 3a.

In this case, since both sides of the first packing 33 extend upward, water droplets enter the input display case 3 from the corners on both sides of the lower side of the opening 3 a of the input display case 3. Can be reliably prevented. In addition, inclined portions 33a, 35a are formed at the joints between the upper ends of the portions extending upward on both sides of the first packing 33 and the corresponding lower ends of the third and fourth packings 35, 36. Is formed so that the height gradually decreases from the outside to the inside of the opening 3a of the input display case 3, so that when the water droplet flows from the upper side to the lower side, the inclined portions 33a and 35a are inclined. The water droplets can be guided from the edge of the opening 3a of the input display case 3 to the surface side of the input display panel 4 along this, and this also reliably prevents the water droplets from entering the input display case 3. be able to.

In addition to being able to take in, since the intake port 11 is provided on the rear side of the apparatus body 1, even if the intake port 11 is provided on the upper surface side of the apparatus body 1, the intake port 11 is not easily blocked. Therefore, the outside air can be taken in well and reliably.

Further, in this information processing apparatus, the duct portion 13 for guiding the outside air taken in from the air inlet 11 into the apparatus main body 1 is provided to the cooling fan 7, so that the inclination provided at the upper edge of the apparatus main body 1 is provided. Even if the air inlet 11 is provided in the portion 10, the outside air taken in from the air inlet 11 by the duct portion 13 can be reliably guided to the cooling fan 7. For this reason, the cooling fan 7 is not restricted in the installation position in the apparatus main body 1 and can be installed in an optimum position in the apparatus main body 1, so that the component unit 8 in the apparatus main body 1 can be installed. Can be efficiently cooled.

That is, even if the intake port 11 is provided in the inclined portion 10 provided at the upper edge of the apparatus main body 1, the cooling fan 7 is disposed in the apparatus main body 1 located on the right side of the intake port 11, and the cooling fan 7 The component unit 8 that generates heat is arranged on the left side of the component unit 8, and an exhaust port 14 for discharging the air that has cooled the component unit 8 to the outside is provided at the lower side of the apparatus body 1 located on the left side of the component unit 8. Since the air can be efficiently blown by the apparatus main body 1 by 7, the component unit 8 can be efficiently cooled by the cooling fan 7. Thereby, since the product unit 8 does not generate heat more than the allowable value, the life of various electronic components mounted on the component unit 8 can be extended, and the quality of the product can be improved.

In addition, since this information processing apparatus includes the intake air adjustment member 14 for adjusting the intake range for taking outside air from the intake port 11, the intake air amount of the intake port 11 can be adjusted by the intake air adjustment member 14. Thereby, the cooling capacity by the cooling fan 7 can be adjusted. For example, if the component unit 8 is a model that generates a small amount of heat, the intake adjustment member 14 can narrow the intake range of the intake port 11 to reduce the amount of external air taken in from the intake port 11. . For this reason, it is not necessary to replace the cooling fan 7 in accordance with the amount of heat generated by the component unit 8, and the component unit 8 can be efficiently cooled with an optimal cooling capacity.

In this case, the intake adjustment member 14 is configured to change the duct area of the duct portion 13 according to the adjustment of the intake range, and to cause a part of the intake port 11 to function as the exhaust port according to the change of the intake range. Thus, when the intake range of the intake port 11 is narrowed by the intake adjustment member 14, the range in which the intake adjustment member 14 has moved, that is, the duct region that is partitioned by the intake adjustment member 14 and located on the side opposite to the cooling fan 7 is set. It can be opened in the apparatus main body 1. As a result, a part of the intake port 11 can be used as an exhaust port, so that the air that has cooled the component unit 8 in the apparatus body 1 can be discharged from the intake port 11 together with the discharge port 15 to the outside of the apparatus body 1. Therefore, the component unit 8 can be efficiently cooled also by this.

Further, in this information processing apparatus, the exhaust amount can be adjusted by adjusting the exhaust range of the exhaust port 15 by the exhaust adjustment member 16, so that the exhaust adjustment is performed when the model of the component unit 8 has a small heat generation amount. The exhaust range of the exhaust port 15 can be narrowed by the member 16 and the exhaust amount of the air discharged from the exhaust port 15 can be reduced, and this can also adjust the cooling capacity. The component unit 8 can be efficiently cooled, and by restricting the exhaust port 15 to be narrow, generation of noise can be suppressed, so that silence can be improved.

Further, in this information processing apparatus, a water droplet discharge path 17 is provided inside the apparatus main body 1 for guiding water droplets that have entered from the air inlet 11 to the outside of the apparatus main body 1. Even if it falls and enters the apparatus main body 1 from the air inlet 11, it does not affect the component unit 8 in the apparatus main body 1, and the entered water droplets are discharged well and reliably to the outside of the apparatus main body 1. Can do. For this reason, even if the air inlet 11 is provided in the upper part of the apparatus main body 1, a failure of the component unit 8 in the apparatus main body 1 due to intrusion of water droplets, a main part such as a circuit board mounted on the component unit 8 shoots, etc. Can be prevented from occurring.

That is, when a water droplet enters the apparatus main body 1 from the air inlet 11, the water droplet discharge path 17 drops the water droplet along the water droplet guide rib 12 onto the flow plate 18 as shown in FIG. A water droplet flows along the inclination of the plate 18 toward the outer peripheral side of the upper case 1 a and flows into the vertical flange portion 19, and the poured water droplet is guided downward by the vertical flange portion 19 to upper case of the apparatus main body 1. It can be reliably discharged to the outside of the apparatus main body 1 through a gap 20 provided at the joint between 1a and the lower case 1b.

Further, in this information processing apparatus, a device mounting portion 6 for mounting an input display device 2 as an external connection device is provided on the upper portion of the device main body 1, and the device main body 1 located around the device mounting portion 6 is provided. Since an auxiliary water droplet discharge path 23 for guiding water droplets entering from the periphery of the device mounting portion 6 to the outside of the device main body 1 is provided inside, the water drops fall on the device mounting portion 6 of the device main body 1 Even if it enters the apparatus main body 1 from the surroundings, it does not affect the component unit 8 in the apparatus main body 1, and the entered water droplets can be discharged well and reliably to the outside of the apparatus main body 1. For this reason, even if the device mounting portion 6 for mounting the input display device 2 that is an external connection device is provided on the upper portion of the apparatus main body 1, a failure of the component unit 8 in the apparatus main body 1 due to the intrusion of water drops, It is possible to prevent the occurrence of problems such as the main parts such as the mounted circuit board shooting.

In other words, the auxiliary water droplet discharge path 23 is formed on the outer periphery of the lower portion of the mounting cover 22 when water drops fall on the mounting cover 22 of the device mounting portion 6 and enters the apparatus main body 1 from the periphery of the mounting cover 22. The discharge groove 24 provided leads to the lower front side of the mounting cover 22, and the introduced water drops are collected and dropped onto the middle lower part of the mounting cover 22 by the flange 25, and the dropped water drops are discharged to the apparatus main body by the discharge passage 26. 1 can be reliably discharged to the outside of the apparatus main body 1 through a gap 27 provided at the joint between the upper case 1a and the lower case 1b.

Further, in this information processing apparatus, when the input display device 2 provided on the apparatus main body 1 provides the input display panel 4 in the input display case 3, the edge of the opening 3a in the input display case 3 and the input display are displayed. Since the frame-shaped drip-proof packing 30 is provided between the peripheral edge of the panel 4, even if water drops adhere to the input display case 3 and the input display panel 4 of the input display device 2, The drip-proof packing 30 can prevent adhering water droplets from entering the input display case 3.

That is, the drip-proof packing 30 includes a first packing 33 disposed on the lower side of the opening 3 a of the input display case 3 and a second packing 34 disposed on the upper side of the opening 3 a of the input display case 3. And the third and fourth packings 35 and 36 respectively disposed on both sides of the opening 3a of the input display case 3, the input display case 3 and the input display panel 4 Even if the adhering water droplets flow from the upper side to the lower side, the first to fourth packings 33 to 36 provided in the opening 3a of the input display case 3 reliably prevent entry into the input display case 3. can do.

In this case, since both sides of the first packing 33 extend upward, water droplets enter the input display case 3 from the corners on both sides of the lower side of the opening 3 a of the input display case 3. Can be reliably prevented. In addition, an inclined portion 33a is formed at a joint portion between each upper end portion of the portion extending upward on both sides of the first packing 33 and the corresponding lower end portion of each of the third and fourth packings 35 and 36. , 35a are formed so that the height gradually decreases from the outside to the inside of the opening 3a of the input display case 3, so that when the water droplets flow from the upper side to the lower side, the inclined portions 33a, 35a Water droplets can be guided along the inclination from the edge of the opening 3a of the input display case 3 toward the surface of the input display panel 4, and this also ensures that the water droplets enter the input display case 3. Can be blocked.

Moreover, since this drip-proof packing 30 is divided | segmented into each 1st-4th packing 33-36, as shown in FIG. 21, it can plate efficiently from one rubber sheet 38, Thereby, compared with the case where the drip-proof packing 30 is formed continuously in a frame shape, the material is not wasted and the cost of the material can be reduced.

In other words, the drip-proof packing 30 is plated in a state where the third and fourth packings 35 and 36 on both sides are laid sideways between portions extending upward from both sides of the first packing 33. Since the entire area can be reduced to the initial limit by cutting the upper side side second packing 34 on the upper side, a plurality of sets of drip-proofing can be made from one rubber sheet 38. The packing 30 can be cut out.
