2. Description of the Related Art Conventionally, in an information processing apparatus in which a power supply unit is mounted inside a housing, a work space required for maintenance and expansion is secured, and the power supply unit is arranged at a position where it does not interfere with the work space. In addition, at the time of maintenance and expansion work, once the power supply unit is removed from the housing, maintenance and expansion work is performed, and then the power supply unit is assembled again.

However, by securing a work space necessary for maintenance and expansion and arranging the power supply unit at a position where it does not interfere with the work space, the volume of the housing is inevitably increased. This was a factor that hindered space saving. Further, in the method of once removing the power supply unit outside the housing, performing maintenance and expansion work, and then assembling the power supply unit again, the maintainability and the workability at the time of expansion are significantly impaired.

An object of the present invention is to provide an information processing apparatus capable of improving workability in maintenance and expansion and realizing space saving.

An information processing apparatus according to the present invention has a main circuit board, a power supply unit, and an external storage device integrally mounted in a housing provided with a flat information display means on one main surface. In an information processing device with a structure, access to the inside of the housing can be easily made by removing the cover on the back of the housing, and the power supply unit has a movable structure. For example, by tilting and displacing to the outside of the housing, a work space is secured on the main circuit board and the like to improve workability, and the power supply unit is placed inside the housing during normal operation other than during maintenance work. By pulling in and fixing, space saving can be realized.

That is, the back cover 1a behind the main body 1
When viewed from the side, the power supply unit 8 is located on the near side, and the motherboard 3 and a plurality of PCIs supported on the motherboard 3 via the riser card 3c are located on the back side.
An extension component such as the substrate 10 is provided.

[0010] The microprocessor 3a mounted on the motherboard 3 is cooled by a cooling fan 3b. Also,
The power supply unit 8 includes a cooling fan 8a.

FIG. 3 is a perspective view exemplifying a detailed structure of the power supply unit 8 and a metal plate (hereinafter, referred to as a power supply mounting plate 11) serving as a support for mounting the power supply unit 8 inside the main body 1.

On both left and right sides of the power supply unit 8, cylindrical projections 12 serving as rotation axes when rotating the power supply unit 8 are provided.
Is provided on the power supply mounting sheet metal 11 supported on the housing side.
The power supply unit 8 is rotated (tilted) by providing a through hole 13 for receiving the shaft and inserting the projection 12 into the through hole 13.
It has a structure to make it.

In this case, a structure in which the projection 12 is formed on the side of the power supply mounting sheet metal 11 and the through hole 13 is formed on the side of the power supply unit 8 may be employed.

The power supply unit 8 is provided with a fixture 15 having a through hole 15a for fixing the power supply unit 8 to the main body 1 with a screw (not shown) and a fixture 16 having a through hole 16a. ing.

When the power supply unit 8 is tilted, the power supply mounting plate 11 is tilted so that the power supply unit 8 does not rotate beyond a specified tilt angle θ (θ = 30 degrees in the present embodiment). A stopper portion 14 having an inclined surface which comes into contact with the fixing bracket 15 is provided.

Hereinafter, an example of the operation of the present embodiment will be described.

At the time of normal use of the information processing apparatus of the present embodiment, fixing brackets 15 and 16 provided on power supply unit 8 are provided.
