  In the case of the present embodiment, the distance h from the bottom portion 36 a of the holding portion 36 to the offset position P to which the flexible hinge 40 is connected in the support plate 18 is set larger than the thickness dimension t of the base 16 and the keyboard device 28. Has been. As a result, when the bottom portion 36a of the holding portion 36 moves toward the keyboard device 28 when the tablet PC 12 is opened, the bottom edge portion of the support plate 18 is slidably contacted with the upper surface of the front cover portion 22 (bottom plate 26). The hinge hinge 40 is pushed up, and the rear end side of the keyboard device 28 rises together with the base 16. As a result, since the keyboard device 28 is tilted forward in the stand posture, the operability of the keyboard device 28 is improved.

  In the cover stand 10, the back cover portion 20 is provided between the fixing portion 20 a fixed to the support plate 18, and the fixing portion 20 a and the connecting portion 24, and the portion from the support plate 18 toward the flexible hinge 40 side. The movable portion 20b that can be separated from the fixed portion 20a and the boundary portion between the fixed portion 20a and the movable portion 20b. And a second fold line B2 in the horizontal direction parallel to the first fold line B1. And the standing angle of the tablet PC 12 in the stand posture can be changed by folding the first fold line B1 from the stand posture in a state where only the second fold line B2 is folded. Thereby, the user simply folds the upper part of the movable part 20b by folding the first fold line B1 using the index fingers of both hands from the stand posture of the standing angle of about 65 degrees shown in FIGS. 2 and 6, for example. For example, the stand posture can be changed to a stand angle of about 50 degrees as shown in FIGS. For this reason, this angle change can also be performed in one action. For example, when the cover stand 10 is used on the knee, it can be easily changed to an optimum angular position for use, and convenience is further improved. .

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.
