In the portable wireless device described in Patent Document 1, an upper housing having a receiver for receiving the voice of the other party, a transmitter for transmitting the voice to the other party, a key operation unit having key buttons, and a radio circuit component Is connected via a hinge portion or by a slide structure, and the upper housing and the lower housing are used in a state where the overlapping state of the upper housing and the lower housing is released during a call. For this reason, since the upper housing having the handset is not provided with a power amplifier or the like which is a radio circuit component generating a large amount of heat, the heat of the power amplifier or the like is transmitted to the user's ear and makes the user feel uncomfortable during a call. There is no. Further, since the lower housing is provided with the wireless circuit board and the display unit, the weight of the lower housing is larger than the weight of the upper housing. For this reason, the caller always has a heavy lower housing, and there is no need to change the housing when operating keys.
[0004]
Further, in the telescopic telephone described in Patent Document 2, an antenna and a high-frequency component are arranged on an upper part (upper case) of the telephone, and a power source and a main part of a key are arranged on a lower part (lower case). The upper and lower parts are movably attached to each other. Alternatively, a hinge is provided between the upper and lower portions so that the upper and lower portions are pivotally movable. Therefore, the antenna provided on the upper part is not hidden by the user's hand. Also, since the battery attached to the bottom is a rather heavy component, it is most natural for the user to hold the bottom of the phone with one hand during operation.

The reduction gear portion 50b preferably has a spur gear structure made of resin such as engineer plastic in consideration of noise reduction. Further, in order to enhance the operation reliability, a clutch mechanism and a torque limiter mechanism (not shown) may be interposed in the reduction gear unit 50.
[0030]
When the release button 32 shown in FIG. 6 is operated to release the locking of the locking lever 30, the upper housing 2 is moved relative to the lower housing 1 by the action of the expansion spring 22 until the second mounting state 22b is reached. It moves to the second state. In this process, the moving speed at which the upper housing 2 moves with respect to the lower housing 1 is suppressed by the action of a rotational load torque such as a magnetic attraction force, a shaft loss, and a deceleration load of the motor drive unit 50, and The mechanical shock when the body 2 reaches the second position is reduced.
[0031]
The time required for the upper housing 2 and the lower housing 1 to move from the overlapped state to the open state is preferably 1 second or less. In addition, since the movement from the open state to the superposed state can be manually performed by the user without depending on the driving of the motor driving unit 50, the operation is guaranteed even when the battery unit 5 does not function. Further, when the motor drive unit 50 is performing the speed suppressing action, an electromotive force is generated in the small DC motor 50a constituting the motor drive unit 50, so that the battery unit 5 of the mobile phone is charged with the electromotive force. It can be refluxed and used effectively as a power source.
[0032]

Further, a configuration may be adopted in which a position detection sensor (switch) (not shown) is provided between the upper housing 2 and the lower housing 1 and the motor driving unit 50 is driven by slightly moving the upper housing 2. .
[0033]
As described above, according to the mobile phone of the present embodiment, the upper housing 2 and the lower housing 1 can be easily switched between the overlapped state (first state) and the open state (second state). It can be moved smoothly by the mechanism structure. That is, when the user performs a one-touch operation on the lock release mechanism, the mobile phone can be very easily and instantaneously changed from the overlapping state of the upper housing 2 and the lower housing 1 to the open state. In addition, by providing the second release button 33 on the upper housing 2, a lock release operation can be performed on the upper surface of the mobile phone.
[0034]
Further, if the sliding rail portion 20 shown in FIG. 4 is configured to be slightly curved, as shown in FIG. 9, when the upper housing 2 and the lower housing 1 are in the open state (second state). The shape of the housing follows the curved surface curve (reference numeral R shown in FIG. 9) of the user's cheek as compared with the linearly moving slide. For this reason, since the user's head and the antenna 4 arranged in the lower housing 1 are separated (reference E in FIG. 9), the antenna sensitivity can be improved even during a call. As a result, it is possible to improve the call characteristics.
[0035]
8 so that the moving speed of the upper housing 2 relative to the lower housing 1 is suppressed, and the mechanical shock when the upper housing 2 reaches the lower housing 1 can be reduced. Because of the mechanism, the impact at the moving end when the upper housing 2 and the lower housing 1 move from the overlapping state to the open state can be reduced. In addition, since the speed control mechanism includes the motor driving unit 50, the upper housing 2 and the lower housing 1 can be automatically moved from the open state to the overlapped state.
[0036]
Further, since the upper housing 2 is provided with the receiver 7 and the microphone 8, it is possible to talk even when the upper housing 2 and the lower housing 1 are overlapped, and the upper housing 2 and the lower housing 1 are open. Can be communicated under the same characteristic conditions.
[0037]
【The invention's effect】
As described above, according to the mobile phone of the present invention, it is possible to provide a small and thin mobile phone that ensures high operability with excellent instantaneous response and maintains good antenna sensitivity even during a call. .
