2. Description of the Related Art FIGS. 5A and 5B are schematic perspective views showing one structural example of an electronic module, and FIG. 6 is a schematic perspective view showing one structural example of a conventional information processing apparatus.

As shown in FIGS. 5 (a) and 5 (b), an electronic module 50 is a box-type electronic device having a printed wiring board (not shown) inside, and the electronic module 50 is mounted on the front side of the device frame. Handle 52 used when mounting on 80 (described later)
On the back side, a connector 51 to be connected to a mating connector (not shown) when the module is mounted on a module mounting section 81 (described later) on the device frame 80 side is equipped. In these electronic modules 50, the printed wiring board and the like are cooled by cooling air α flowing through a ventilation hole 55 penetrating from the bottom surface portion to the ceiling portion.

The electronic module 50 is mounted on the module mounting portion 81 of the device frame 80 as shown in FIG. In the figure, 81 is a module mounting portion for mounting the electronic module 50, 83 is an intake hole for sucking the cooling air α, 84 is an exhaust hole for discharging the cooling air α sucked from the intake hole 83 to the outside of the apparatus, and 85 is cooling air. Reference numeral 90 denotes an air filter arranged to remove dust and the like contained in α, and reference numeral 90 denotes an axial fan for circulating the cooling air α at a high speed.

Since this information processing apparatus is an active maintenance type, even if the electronic module 50 is removed from the module mounting portion 81 for maintenance and inspection as shown in FIG. The electronic module 50 of the device has been removed) and the device will continue to operate.

[0007]

This active maintenance type device is designed to continue operating even if the electronic module 50 is removed. However, the electronic module
When 50 is removed, the front portion (inlet portion) of the module mounting portion 81 becomes open, as apparent from FIG. 6, so that the outside air β flows into the device frame 80 from there.
However, since the outside air β does not pass through the air filter 85, it naturally contains dust. Therefore, when the outside air β enters the module mounting portion 81, the electronic components mounted inside the device are contaminated and the reliability is lowered.

Further, when the electronic module 50 is pulled out, the regular cooling air α flowing from the intake hole 83 also "passes through" there, so that the balance of the overall air flow is lost. Since the balance of the air flow is an important factor for ensuring the cooling efficiency, if the balance of the air flow is lost, the overall cooling efficiency will be reduced.

The present invention is intended to realize an information processing apparatus in which the operating reliability of the active maintenance type information processing apparatus is remarkably improved by preventing outside air β from entering the module mounting portion even if the electronic module is pulled out. Is.

[0010]

The information processing apparatus according to the present invention, as shown in FIG. 1, changes its posture when the electronic module 50 is mounted on the module mounting portion 81 and opens the module mounting portion 81. Further, when the electronic module 50 is removed, the posture-changing front lid 10 that returns to the original posture and closes the module mounting portion 81 is attached to the device frame 80 side.

[0011]

When the electronic module 50 is mounted, the information processing apparatus is opened inward to open the entrance of the module mounting portion 81, and when the electronic module 50 is removed, the information processing apparatus returns to the original posture and the module mounting portion 81 is opened. Since the front lid 10 that closes the entrance of the
Even if removed from 81, outside air β (see FIG. 6) does not flow into the device. Therefore, active maintenance work of the electronic module 50 can be performed without impairing the cooling function of the device.
