Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen input and a keyboard input by rotatably connecting a display unit for performing pen input and an input unit for performing key input. The present invention relates to an information processing apparatus (personal computer) that enables the above. 2. Description of the Related Art FIGS. 5 (a), 5 (b) and 5 (c) are views showing an example of the configuration of a conventional personal computer, in which 1 is a pen input surface 1a.
A display unit having a key input surface 20a;
50 is a hinge for rotatably connecting the display unit 1 and the input unit 20; 60 is a support leg for supporting the display unit 1 so that the tilt angle can be adjusted;
Reference numeral 13 denotes a leg holding hole for holding the supporting leg 60 so that the posture can be changed. FIG. 5 (a) is a view showing a state in which a conventional personal computer is used by placing it on a flat table such as a desk or the like. In this case, the input unit 20 has the key input surface 20a facing upward. The display unit 1 on which one pen can be input is placed with the pen input surface 1a facing obliquely upward via the support leg 60. In this case, the inclination angle of the display unit 1 is adjusted by changing the posture of the support leg 60. FIG. 5B shows a pen input surface 1a and a key input surface 20a.

However, otherwise (for example, when the operator places the device on his / her knee or operates the device while standing up, etc.), there is nothing to specify the relative position between the display unit 1 and the input unit 20. As a result, the relationship between the two becomes extremely unstable, and the display unit 1 easily rotates in the direction of arrow C about the hinge 50 as a rotation center, as shown in FIG. 5B, for example. As described above, in the conventional personal computer, when the display unit 1 capable of pen input and the input unit 20 capable of key input are used in the same plane, the related position cannot be specified. Therefore, it was impossible for the operator to operate the personal computer by placing it on his / her knee (or operating it while standing up).
When the pen input surface 1a and the key input surface 20a are used on the same plane, the support leg 60 normally assumes the posture shown in FIG. 5B. FIG. 5C shows a state in which this device is carried and carried. When carrying this personal computer, the input unit 20 is rotated in the direction of the arrow so that the display unit 1 and the input unit 20 are overlapped as shown in the figure. At this time, the support legs 60
Is the posture shown in FIG. 5 (c). When a conventional personal computer is used in the state shown in FIG. 5B, "the positional relationship between the display unit 1 and the input unit 20 becomes unstable." As mentioned above, this is not a job. However, this type of personal computer is attractive because it can be easily operated using idle time while carrying (for example, if you are in a car, you can also enter on your knees while sitting down on your seat) Considering its future potential, it is necessary to improve it so that it can be operated with high stability even while it is being carried. An object of the present invention is to provide an information processing apparatus which can be operated stably even when the display unit and the input unit are in the same plane. As shown in FIG. 1, the personal computer according to the present invention has an input unit 20, a display unit 1 rotatably connected to the input unit 20, and a display unit. And a support leg 30 for supporting the unit 1 and adjusting the inclination angle of the display unit 1. A leg movement guide formed on the display unit 1 and holding the support leg 30 slidably. 3, a leg engagement groove 25 formed in the input portion 20 and into which a part of the support leg 30 is engaged, and a leg lock mechanism for locking the support leg 30 engaged in the leg engagement groove 25. 40. According to the present invention, the support leg 30 for adjusting the inclination angle of the display unit 1 slides along the leg movement guide 3 formed on the display unit 1 and a part thereof is moved to the input unit 20 side. The display unit 1 and the input unit 20 are brought into a flat state by being engaged in the formed leg engagement groove 25, and a part of the support leg 30 engaged in the leg engagement groove 25 is locked by the leg lock mechanism 40. As a result, the attitudes of the display unit 1 and the input unit 20 which are in a planar state with each other are stabilized. For this reason, the input unit 20 and the display unit 1 are originally provided by using the support legs 30 that support the tilt angle of the display unit 1 so as to be adjustable.
Can be held in the same plane, and the stability when the information processing apparatus is operated during transportation or the like is increased.
