Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information processing apparatus, and more particularly to an information processing apparatus having a display mechanism that guides light emitted from a plurality of light emitting elements to a display surface of a housing to emit light.
[0002]
[Prior art]
In recent years, as information processing apparatuses have been made thinner, various considerations have been given to the arrangement of LEDs (Light Emitting Diodes) or the like for displaying the internal state of the apparatus.
[0003]
By the way, when information is to be displayed by a plurality of LEDs, the mounting area occupied by these LED groups should be as small as possible and light emitted from the individual LEDs should not interfere with each other. It is necessary to keep in mind.

Therefore, in the past, for example, a method of connecting a light emitting portion of each LED and a display surface of a housing with a light guide has been used.
[0005]
[Problems to be solved by the invention]
However, such a method has a problem that the work of connecting the light guides is required in the assembling process, and the work becomes complicated, resulting in an increase in the assembly cost of the apparatus.
[0006]
In addition, the number of light guides is required as many as the number of LEDs, and a shielding member for preventing light interference is also required, resulting in an increase in the number of parts.
The present invention has been made in view of the above points, and an object thereof is to provide an information processing apparatus having a display mechanism that can be easily assembled and can be downsized.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention includes a housing having an open front portion and a lid portion that is attached to the front portion of the housing and forms a display surface, and is emitted from a plurality of light emitting elements.

Further, since the display mechanism 3 and a circuit for driving the display mechanism 3 are mounted on the sub-board 2b different from the main board 2a on which the information processing circuit is mounted, the display mechanism 3 is added as necessary. The work of the case can be simplified. For example, when the display mechanism 3 is an option, when assembling a device including this option, the work is completed simply by mounting the sub board 2b and connecting it by the flat cable 2r.
