Then, the upper housing 3 is moved in the CCW direction so that the upper surface is closed (FIG. 13). Further, in this case, since the upper surface is moved in the CCW direction, the teeth necessary for the second rotating plate gear 61 to move in the CCW direction are formed on the second rotating plate gear 61. Therefore, movement in the CCW direction is prevented.
- 16 to 18 are plan views showing the internal state of the portable terminal 1b showing another example in which the tooth formation range of the second rotating plate gear 62 is a part of the entire circumference of the gear. is there.
