  According to the portable computer 1 configured as described above, it is possible to improve design and operability. The effects of each configuration according to this embodiment will be described below.

(Speaker mounting surface)
When the opening for exposing the speaker and the palm rest surface are located on the same plane, for example, when the user's hand is placed on the palm rest surface when using a keyboard, the user's hand can easily block the opening, The sound from the speaker may be blocked by the user's hand.

  On the other hand, in the portable computer 1 according to the present embodiment, the speaker mounting surfaces 32 and 33 in which the openings 36 for exposing the speakers 21 and 22 are formed are recessed with respect to the palm rest surface 31 and are lower than the palm rest surface 31. Yes. According to such a configuration, even when the user's hand H is placed on the palm rest surface 31 when the keyboard is used, a space is easily secured between the user's hand and the speaker mounting surfaces 32 and 33, It is difficult for the hand to block the opening 36 of the speaker mounting surfaces 32 and 33.

  Thereby, the sound output from the speakers 21 and 22 is not easily blocked by the user's hand, and a good sound can be delivered to the user. In other words, the user can use the keyboard 12 without worrying about closing the opening 36 with a hand. Thereby, the operability of the portable computer 1 is improved.

  The portable computer 1 includes a speaker cover 45 attached to the openings 36 of the speaker attachment surfaces 32 and 33, and the speaker cover 45 is formed in a dome shape and rises above the speaker attachment surfaces 32 and 33. The sound passage 47 is provided in the upper surface portion 46. According to such a configuration, even when the user's hand H is located above the speaker cover 45, the sound passage 47 is not easily blocked by the user's hand H. Thereby, the sound from the speakers 21 and 22 is further less likely to be blocked by the user's hand.

  If the boundary 44 between the speaker mounting surfaces 32 and 33 and the palm rest surface 31 is formed in an arc shape that protrudes from the speaker mounting surfaces 32 and 33 toward the palm rest surface 31, the boundary 44 is rounded. The part is easy to fit the user's hand. Thus, the user can put his / her hand on the palm rest surface 31 where the speaker mounting surfaces 32 and 33 are adjacent without feeling uncomfortable, thereby improving the operability.

(Palmrest surface)
If the touch of the palm rest surface 31 and the touch of the touch pad surface 34 are similar to each other, it is difficult to distinguish between the palm rest surface 31 and the touch pad surface 34 due to, for example, the touch of a fingertip. That is, it is necessary to visually identify where the touch pad surface 34 is, and it cannot be said that the operability is sufficiently high in, for example, darkness.

  On the other hand, in the portable computer 1 according to the present embodiment, the palm rest surface 31 is formed to be rougher than the touch pad surface 34, and the coarsely formed palm rest surface 31 surrounds the outer peripheral edge of the touch pad surface 34. It is out. According to such a configuration, the palm rest surface 31 and the touch pad surface 34 can be easily distinguished from each other. That is, it is possible to easily identify where the touch pad surface 34 is due to the touch of a fingertip or the like. This contributes to improving the operability of the portable computer 1. In addition, when the touch pad surface 34 is formed in a rough shape, fingerprint traces are hardly left and maintainability is improved.

  If the palm rest surface 31 and the touch pad surface 34 are formed on the same surface, the above effects are more easily exhibited. Furthermore, the portable computer 1 having a novel design in which the touch pad surface 34 and the palm rest surface 31 coincide with each other can be provided.

(functional parts)
If a plurality of functional parts (for example, connectors) are arranged at the same height position, the front side functional parts may be in the way, making it difficult to use the back side (that is, rear side) functional parts.

  On the other hand, the portable computer 1 according to the present embodiment includes a first functional component and a second functional component disposed farther than the first functional component as viewed from the user. However, when the portable computer 1 is placed on the desk surface T, it is mounted at a position where the height from the desk surface T is higher than that of the first functional component. According to such a configuration, when using the functional component on the back side, the functional component on the front side is not easily obstructed, and the usability of the functional component on the back side (for example, ease of attaching / detaching the cable) is improved. . That is, the operability of the portable computer 1 is improved.

When the side walls 6c and 6d are formed in a tapered shape that protrudes to the outside of the housing 4 as it goes downward, the visibility (that is, visibility) of the connector on the back side as viewed from the user side is improved. Usability of functional parts is further improved The first and second functional parts are port connectors, and both of the first and second functional parts are farther from the center of the side walls 6c and 6d when viewed from the user. When the portable computer 1 is used, the cables connected to the first and second functional components, which are port connectors, do not get in the way when the portable computer 1 is used, and the operability of the portable computer is further improved.

(leg)
In a portable computer having I-shaped legs extending in the front-rear direction of the housing, when a backward load is applied to the portable computer, the portable computer tends to move backward and cannot be used stably. is there.

  On the other hand, in the portable computer 1 according to the present embodiment, the rubber leg portions 73 and 74 include a V-shaped bent portion 75 with the apex 75a facing the user side. When such a bent portion 75 is provided, when a backward load is applied to the portable computer 1, the leg portions 73 and 74 are easily strutted and the portable computer is difficult to move backward. Thereby, the portable computer 1 can be stably operated, and the operability of the portable computer 1 is improved.

  On the other hand, for example, when using ODD or CD-ROM, the portable computer 1 may be pulled forward. The bent portion 75 does not work well in the forward direction (that is, the movement toward the user side) and does not have a large resistance. For this reason, when the bent portion 75 is provided, it is possible to obtain the portable computer 1 that is difficult to move backward and easy to move forward.

  When the leg portions 73 and 74 are formed in a Y shape having a linear portion 78 extending from the apex 75a of the bent portion 75 to the user side, the leg portions 73 and 74 are further stabilized and the operation of the portable computer 1 is performed. The nature is further improved.

  The portable computer 1 according to one embodiment of the present invention has been described above, but the present invention is not limited to this. The present invention can be embodied by modifying the components without departing from the scope of the invention in the implementation stage.

  For example, the boundary portion 44 between the speaker mounting surfaces 32 and 33 and the palm rest surface 31 does not need to be formed in an arc shape. The upper surface portion 46 of the speaker cover 45 does not need to be formed in a dome shape. The touch pad surface 34 and the palm rest surface 31 are not necessarily on the same surface. The leg portions 73 and 74 are not limited to the Y shape, and may be formed in a V shape.
