Accordingly, the panel holding portion 28 can be securely fixed to the main circuit board 9.

  Further, since the connection holding portion 29 is provided with an auxiliary hook 33 detachably engaged with the edge of the main circuit board 9 located on the opposite side of the opening 11 of the main circuit board 9, this auxiliary hook is provided. The connection holding part 29 can be attached to the opening part 11 of the main circuit board 9 simply and reliably by 33. In this case, the auxiliary hook 33 extends from the upper side of the connection holding part 29 toward the edge of the main circuit board 9 located on the opposite side of the opening 11 of the main circuit board 9 while avoiding the electronic components 9a to 9d. Part 33a and a hook part 33b provided at the tip of the arm part 34, and the hook part 33b is locked to the edge of the main circuit board 9 in a state of crossing the main circuit board 9, The connection holding portion 29 can be reliably fixed to the main circuit board 9.

  In the above embodiment, the case where the electronic device is applied to an electronic dictionary has been described. However, the electronic device is not necessarily an electronic dictionary. For example, a portable information terminal (PDA: personal digital assistant), a portable personal computer, or the like. It can be widely applied to electronic devices.

It is the front view which showed one Embodiment which applied this invention to the electronic dictionary. FIG. 2 is an enlarged back view showing a main circuit board and a touch input device incorporated in a first case of the electronic dictionary of FIG. 1. FIG. 3 is an enlarged back view showing the main circuit board of FIG. 2. FIG. 3 is an enlarged front view showing the touch input device of FIG. 4 shows the input display panel of FIG. 4, (a) is an exploded perspective view thereof, and (b) is an enlarged cross-sectional view showing a main part of FIG. 4. FIG. 5 is an enlarged front view showing a state in which the input display panel and the connection circuit member of the touch input device of FIG. 4 are connected. It is the enlarged front view which showed the connection board | substrate of the connection circuit member in FIG. It is the enlarged front view which showed the state which connected each 1st, 2nd film wiring board of the connection circuit member in FIG. 6, and the input display panel. It is the enlarged front view which showed the holder member of the touch input device of FIG. 9 shows each hook provided on the holder member in FIG. 9, (a) is an enlarged cross-sectional view taken along arrow B-B in FIG. 9, showing fixed hooks provided on both the left and right sides of the panel holding portion, and (b). 9 is an enlarged cross-sectional view taken along the line CC of FIG. 9 showing the fixing hook provided on the upper side of the panel holding part, and FIG. 9C is the part A of FIG. 9 showing the auxiliary hook provided on the connection holding part. It is an enlarged side view. FIG. 10 is an enlarged back view showing a reinforcing plate disposed on the panel holding portion of FIG. 9 to reinforce the strength of the input display panel. It is an expanded sectional view of the principal part in the AA arrow of FIG.
