  A detection module for detecting a touch operation or a pressing operation is provided on the printed circuit board 30. Further, these detection modules are arranged below the determination key 70, the touch pad 60, and the left and right up / down direction keys 60a to 60d.

  FIG. 3 is a top view showing an overview of the rubber 40 (elastic member) used in the remote controller 10. The rubber 40 is disposed on the upper surface of the printed circuit board 30. The rubber 40 is, for example, a silicon rubber. The rubber 40 is sized to cover all the metal dome provided on the printed circuit board 30 in a state where the rubber 40 is disposed on the upper surface of the printed circuit board 30. In the present embodiment, the rubber 40 is almost the same size as the printed board 30 and covers the printed board 30 over the entire surface.

  On the upper surface of the rubber 40, operation keys such as a channel key 10a are bonded. The operation key is bonded to the rubber 40 at a position facing the corresponding metal dome in a state where the rubber 40 is disposed on the upper surface of the printed board 30. For example, when the user presses the channel key 30a, the user can obtain a click feeling by the elasticity of the rubber 40.

  Furthermore, the rubber 40 also covers the region of the touch pad electrode 30b in a state where the rubber 40 is disposed on the upper surface of the printed circuit board 30. This is because the determination key metal dome 30c, the up key metal dome 30d, the down key metal dome 30e, the left key metal dome 30f, which need to be covered with the rubber 40 in the region of the touch pad electrode 30b, This is because the right key metal dome 30g is provided.

  Therefore, when the remote controller 10 provided with the touch pad 60a with direction keys as in the present embodiment is manufactured at a low cost, it is necessary to provide the rubber 40 at a position facing the touch pad 60 and the touch pad electrode 30b. is there.

  Here, when the printed circuit board 30, the rubber 40, and the touch pad 60 are simply arranged in this order, the touch pad 60 may malfunction due to a change in capacitance. The cause of malfunction is that bubbles generated between the printed circuit board 30 and the rubber 40 move irregularly when the operation key is pressed. Another reason is that the rubber 40 itself is deformed and moved when the operation key is pressed. Therefore, since the capacitance of the touch pad 60 fluctuates irregularly, the user may not be able to operate the touch pad 60 correctly.

  Therefore, in the present embodiment, the printed circuit board 30 and the rubber 40 are bonded and fixed. The printed circuit board 30 and the rubber 40 can be fixed using an adhesive. In this case, uneven coating of the adhesive causes a malfunction of the remote controller 10. Therefore, as a more preferred embodiment in terms of simplicity and accuracy of bonding, the printed circuit board 30 and the rubber 40 can be fixed using a seal 50 (double-sided adhesive member).

  FIG. 4 is a top view and a side view showing an overview of the seal 50. The seal 50 is a member that adheres the region of the touch pad electrode 30b of the printed board 30 and the rubber 40 facing the region. The seal 50 is approximately the same size as the area of the touch pad electrode 30b. The seal 50 is a thin film seal having a uniform thickness that can be bonded on both sides. Further, the seal 50 is provided with an opening in a cross that is orthogonal to the front-rear and left-right directions. Further, the seal 50 is determined by the size of the opening of the upper key metal dome 30d (similarly, the downward key metal dome 30e, the left key metal dome 30f, and the right key metal dome 30g). The size of the opening in the metal dome 30c portion is large. This is because it is necessary to press down the decision key 70 in comparison with the direction key.

  When the seal 50 is bonded to the area of the touch pad electrode 30b, the seal 50 has an opening key metal dome 30c and an upward key metal dome 30d provided in the area of the touch pad electrode 30b. The down key metal dome 30e, the left key metal dome 30f, and the right key metal dome 30g are not covered. For example, if the determination key metal dome 30c and the printed circuit board 30 are bonded together, the click feeling when the user presses the determination key 70 is reduced. The same applies to other metal dome portions.

  The shape of the seal 50 is not limited to the shape shown in FIG. 4 as long as the region of the touch pad electrode 30b of the printed circuit board 30 and the rubber 40 can be fixed. In addition, the shape of the opening of the seal 50 is as follows: the determination key metal dome 30c, the upward key metal dome 30d, the downward key metal dome 30e, the left key metal dome 30f, and the right key metal dome 30g. The shape is not limited to a cross shape as long as the shape is not covered.

  The seal 50 bonds the area between the touch pad electrode 30b of the printed circuit board 30 and the rubber 40 with a uniform thickness across a horizontal plane.

  FIG. 5 is a top view showing an appearance in which the printed circuit board 30 and the rubber 40 are bonded with a seal 50 and a part of the rubber 40 is cut away.

Further, the determination key metal dome 30c, the upward key metal dome 30d, the downward key metal dome 30e, the left key metal dome 30f, and the right key for the touch pad electrode 30b. The metal dome 30g faces the rubber 40 without the seal 50 interposed therebetween.

  FIG. 6 is a top view showing an overview of the touch pad 60 used in the remote controller 10. FIG. 6 is a diagram in which the touch pad 60 and the enter key 70 are arranged on the upper surface of the rubber 40 bonded to the printed circuit board 30 using the seal 50 shown in FIG. The touch pad 60 has an input surface on the surface, and the enter key 70 also has an input surface on the surface. As with the touch pad 60, the surface of the enter key 70 functions as a touch pad. The touch pad 60 and the enter key 70 can be continuously rubbed. The input surface of the touch pad 60 is arranged so as to surround the input surface of the enter key 70.

  The touch pad 60 is disposed to face the area of the touch pad electrode 30b. The upward key 60a is disposed to face the upward key metal dome 30d. The same applies to the down key 60b, the left key 60c, and the right key 60d. The decision key 70 is also arranged to face the decision key metal dome 30c.
