The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a radiotelephone having a compact external shape with good holding performance without impairing operability. is there.

[0007]

In order to achieve the above-mentioned object, the present invention arranges a dial key group on the front surface of a vertically long and thin casing containing a communication device, and the dial keys are provided on both side surfaces of the casing. A convex grip portion is formed at a position retracted rearward with a step from the arrangement surface of the dial key group and substantially in the center in the longitudinal direction of the housing. A good one is that the grip portion has a convex arc shape in which the substantially center in the longitudinal direction is the most bulged to both sides when viewed from the front, and the end portions in the longitudinal direction converge on both side surfaces of the housing.

In this case, a thin opening / closing lid is attached to one end in the longitudinal direction of the housing via a hinge portion, and the housing has a speaker portion and a hinge portion on the end portion side facing the hinge portion. A dial key group is arranged, and the microphone part is arranged on the end side of the opening / closing lid facing the hinge part. The opening / closing lid hides the dial key group and the microphone part with the opening / closing lid closed, and opens the opening / closing lid. In the closed state, the dial keys may be foldably connected so that the microphone part is exposed. Furthermore, a speaker unit, a display unit, a dial key group, and a microphone unit may be sequentially arranged on the front surface of the housing along the longitudinal direction of the housing.

[0009]

According to the present invention, since the convex grip portions are formed on the both side surfaces of the housing at substantially the center in the longitudinal direction, the housing can be supported by hooking the grip with each finger. At this time, since the grip portion is clearly separated from the dial key group placement surface by a step, it is possible to prevent the finger pressing the grip portion from entering the dial key group placement surface. Further, when viewed from the front, the grip portion is formed into a convex arc shape in which the substantially center in the longitudinal direction is most bulged on both sides, and the end portions in the longitudinal direction are converged on both side surfaces of the housing, so that the whole fits in the hand. In addition, the shape can be tapered in the longitudinal direction of the housing.
