  The stand 30 includes a pair of left and right rotation bases 36 and 36 and a stand plate 38 that connects the rotation bases 36 and 36.

  The bracket portion 20 has a notch-shaped portion 40 at each of the left and right end portions of the one end portion 20b, and a rectangular bulge portion 42 on the back surface 20c between the left and right notch-shaped portions 40, 40. Each rotation base portion 36 has a cylindrical bar shape, and is arranged in a rotatable state in each notch shape portion 40 of the bracket portion 20. A rotation shaft 44 is provided between each rotation base portion 36 and the bracket portion 20. For example, one end portion of the rotation shaft 44 is fixed to the rotation base portion 36 so as not to rotate, and the other end portion is rotatably supported by the bracket portion 20. The stand plate portion 38 is a gate-shaped thin plate member that connects the left and right rotation base portions 36 and 36 so as to wrap around the bulging portion 42. Since the left and right pivot bases 36 are respectively disposed in the left and right cutout-shaped portions 40, the stand 30 can be stored compactly as a part of the outer shape of the bracket portion 20 at the storage position described later.

  In the case of this embodiment, the axis center O of the rotation shaft 44 is arranged coaxially with the axis center of the bracket side hinge shaft 28b (see FIG. 3). The rotational torque of the rotation shaft 44 is set larger than the rotational torque of the main body side hinge shaft 28a and the bracket side hinge shaft 28b.

  The stand 30 opens and closes so that the stand plate portion 38 contacts and separates from the back surface 20 c of the bracket portion 20 by the rotation base 36 rotating around the rotation shaft 44 in the notch-shaped portion 40. Thereby, the stand 30 can be rotated between a storage position (see FIG. 3) along the back surface 20c of the bracket portion 20 and a standing position (see FIG. 1) protruding from the back surface 20c. As shown in FIG. 1, the electronic device 10 sets the stand 30 in an upright position in a usage form of a notebook PC in which the portable information device 14 is opened through the bracket portion 20. Thereby, since the portable information device 14 is held in a predetermined standing posture by the stand 30, the electronic device 10 is prevented from falling backward due to the weight of the portable information device 14.

  Next, the rotation operation of the portable information device 14 in the electronic device 10 will be described.

  FIG. 4A is a side view schematically showing a state of the 0-degree position where the portable information device 14 is closed with respect to the main body housing 24. FIG. 4B is a side view schematically showing a state at a 135-degree position where the portable information device 14 is opened from the state shown in FIG. 4A. FIG. 4C is a side view schematically showing a state at a 180-degree position in which the portable information device 14 is further opened from the state shown in FIG. 4B. FIG. 4D is a side view schematically showing a state at a 360-degree position in which the portable information device 14 is further opened from the state shown in FIG. 4C.

  As shown in FIGS. 3 and 4A, when using the electronic device 10 located at the 0 degree position, the portable information device 14 attached to the bracket portion 20 is opened via the hinge 28, for example, as shown in FIGS. 1 and 4B. Such a desired angular position (for example, 135 degrees) is set. Then, the stand 30 is opened via the rotation shaft 44 and set to a position where the stand plate 38 abuts on the upper surface of the desk, as shown in FIG. 4B. Thereby, since the weight is supported by the stand 30, the portable information device 14 is stably held in a desired standing posture. As a result, the electronic device 10 can use the keyboard 18 or the like while visually checking the display 16 as in a general notebook PC (notebook mode).

  At this time, the pivot shaft 44 of the stand 30 is arranged such that the shaft center O is coaxial with the shaft center of the bracket side hinge shaft 28b. For this reason, the opening operation of the bracket unit 20 (portable information device 14) and the opening operation of the stand 30 coincide with each other in the rotation center and the rotation direction, and high operability is obtained. Note that the axis center O of the rotation shaft 44 may not be arranged coaxially with the axis center of the bracket-side hinge shaft 28b. However, also in this case, it is desirable that the rotation shaft 44 be provided at a position closer to the one end portion 20b than the attachable / detachable surface 20a of the bracket portion 20. Then, since the opening operation of the bracket part 20 (portable information device 14) and the opening operation of the stand 30 coincide in the rotation direction, high operability can be obtained.

  As described above, in the present embodiment, the rotational torque of the rotating shaft 44 is larger than the rotational torque of the main body side hinge shaft 28a and the bracket side hinge shaft 28b. Therefore, when the electronic device 10 at the 0-degree position is set to the notebook mode, the portable information device 14 attached to the bracket unit 20 is once opened to the 180-degree position shown in FIG. A method of returning to the closing direction up to an angular position (for example, 135 degrees) may be used (see the arrow indicated by a broken line in FIG. 4B). That is, once the portable information device 14 is opened to a position of 180 degrees, the stand 30 is pressed to the position and the stand 30 is also opened to a position of 180 degrees that comes into contact with the upper surface of the desk. Subsequently, when the portable information device 14 is returned to the 135 degree position, the rotation shaft 44 having a large rotational torque does not rotate, and only the portable information device 14 is moved to the 135 degree position while the stand 30 is maintained at the 180 degree position. Can be set to Thereby, the electronic device 10 can be set to the note mode more easily. Of course, the rotational torque of the rotation shaft 44 may be the same as or lower than the rotational torque of the main body side hinge shaft 28a and the bracket side hinge shaft 28b. In this case, once the portable information device 14 is opened to a position of 180 degrees and then the portable information device 14 is returned to the closing direction while the stand plate 38 is pressed with a fingertip or the like, the electronic information can be easily obtained as described above. The device 10 can be set to note mode.

  The electronic device 10 can further rotate the portable information device 14 in the opening direction from the 180-degree position shown in FIG. 4C. Then, as shown in FIG. 4D, when the portable information device 14 is in a 360 degree position inverted from the 0 degree position, the accessory device 12 is folded and stored on the back side of the portable information device 14. Thereby, the electronic device 10 can visually recognize and operate the display 16 as a general tablet PC (tablet mode).

  As described above, in the case of the present embodiment, the rotation directions of the opening operation of the portable information device 14 and the opening operation of the stand 30 are the same. Therefore, when the electronic device 10 being used in the note mode shown in FIG. 4B is transformed into the tablet mode shown in FIG. 4D, the portable information device 14 can be rotated from the state shown in FIG. 4B to the 360 degree position. That's fine. If it does so, stand 30 will be pressed by back 20c of bracket part 20 by opening operation of portable information equipment 14, and will be in the storage position which contacted back 20c as it is. Therefore, there is no need to perform an operation of once rotating the stand 30 to the storage position and then transforming it into the tablet mode.

  FIG. 5 is an essential part enlarged side view schematically showing a state where the portable information device 14 is attached to the accessory device 12 </ b> A according to the modified example and is set to the 135-degree position.
