The preparation position P is a position near the tip of the receiving portion 74 and closer to the bottom portion 42 than the receiving portion 74 when the opening / closing portion 32 is closed. Since the contact portion 58 moves to the preparation position P, the contact portion 58 moves toward the rotation shaft 66, which faces left in the figure, and moves toward the bottom portion 42, which faces downward in the figure. When the contact portion 58 moves to the preparation position P, the receiving portion 74 is restored and returns to the hanging state.

  When the user releases the finger from the operation surface 62 and stops the push operation in a state where the contact portion 58 has moved to the preparation position P, the operation portion 34 elastically returns to the original initial position by the restoring force. The initial position of the operation unit 34 is a position when the opening / closing unit 32 illustrated in FIG. 4A is in a closed state.

  FIG. 5 is a diagram illustrating a continuation of the opening operation of the opening / closing unit 32 illustrated in FIG. As shown in FIG. 5A, the operation unit 34 returns to the initial position by a restoring force when the user releases his / her finger from the operation surface 62 after bending after receiving an operation. Due to the elastic return of the operating portion 34, the contact portion 58 contacts the receiving portion 74 so as to lift the receiving portion 74, and rotates the opening / closing portion 32 in the opening direction.

  As shown in FIG. 5B, with the receiving portion 74 placed on the contact portion 58, the opening / closing portion 32 comes out of the opening 31 of the base portion 30, and the user places a finger on the tip of the opening / closing portion 32. Can be pulled out. In this manner, the opening / closing section 32 is lifted by the contact section 58 only by the user pressing the operation section 34, so that the opening / closing section 32 can be reliably opened. Note that even if the receiving portion 74 is bent and comes off the contact portion 58, the state in which the wall portion 68 is caught by the lock portion 64 and the opening / closing portion 32 comes out of the opening 31 is maintained.

  When the user rotates the opening / closing section 32 in the closing direction, the wall section 68 contacts the locking section 64 to rotate the operating section 34 to close the opening / closing section 32, and the operating section 34 returns to the original position by the restoring force, and the locking section 64 The locked part 68a enters and is locked. As described above, since the operation unit 34 can be moved to the original position by the restoring force of the operation unit 34, it can be manufactured at a lower cost as compared with the case where a separate spring is used.

  The contact portion 58 is located at a position shifted from the fixed point 88 of the operation portion 34 toward the rotation shaft 66 of the opening / closing portion 32 when viewed in the rotation axis direction of the opening / closing portion 32 shown in FIG. That is, in the length direction L of the base portion 30, the contact portion 58 is located closer to the rotation shaft 66 than the fixed point 88 of the operation portion 34. Thus, when the operation unit 34 moves to rotate, the contact unit 58 moves to the rotation shaft 66 side, and can move to the preparation position P.

  The operation section 34 is erected from the bottom section 42 of the base section 30, and a fixed point 88 of the operation section 34 is located closer to the bottom section 42 than the contact section 58. That is, the contact part 58 is located above the fixing point 88 in the direction in which the support part 60 is erected. As a result, when the operation unit 34 moves to rotate, the contact unit 58 moves so as to rotate around the fixed point 88, moves to the bottom 42 side, and can move to the preparation position P.

  The operation portion 34 is bent in response to the operation and is unlocked as shown in FIG. 4 (b), and further receives the operation after the lock is released and moves the contact portion 58 to the preparation position P as shown in FIG. 4 (c). Move. As described above, after the rotation of the opening / closing section 32 is released, the contact section 58 is moved to the preparation position P so that the opening / closing section 32 is opened. In this state, the lock release has been completed, and the opening / closing section 32 can be reliably rotated in the opening direction.
