Two magnetic elements 611 and 612 are provided on a main body 61, and three magnetic elements 621, 622 and 623 are provided on a sliding cover 62. When the sliding cover 62 slides downward along the arrow, repelling force is generated between the magnetic elements 611 and 621. The user has to overcome the repelling force to push downward the sliding cover. Please refer to FIG. 1b. When the sliding cover 62 moves to close to the position shown in FIG. 1b, the magnetic element 611 and the magnetic element 622 generate repelling force again, and the user needs to overcome the repelling force. Finally, when the sliding cover 62 moves to the position shown in FIG. 1c, the user has to overcome the repelling force generated by the magnetic element 612 and the magnetic element 623 for the last time. Although at the positions shown in FIG. 1a and FIG. 1c, the sliding cover 62 and the main body 61 position utilizing the repelling force between the magnetic elements 611, 621 and the magnetic elements 612, 623 (the user has to overcome the repelling force to move the sliding cover 62). The user won't move smoothly the sliding cover 62 from the position shown in FIG. 1a to the position shown in FIG. 1c for the repelling force, so that the conventional slidable mobile phone 60 cannot provide a good operation feel. Please refer to FIG. 2. Conventional keys 624 are provided on the sliding cover 62 of the slidable mobile phone 60, and can only provide a downward press function. Since functions of the mobile phone are increased day after day, and the conventional keys 624 cannot provide a browsing function to rapidly operate and control the mobile phone, a pointing device by detecting the pressed direction such as a joystick, or a browsing control key (such as a hall device) which can slide on a two-dimensional surface may be preferred choice.
U.S. Pat. No. 6,950,316 which is titled “electronic device with a slidable cover member” discloses a conventional slidable mobile phone 70. Please refer to FIG. 3.

However, when a user operates the pointing device by detecting the pressed direction, he often needs to press the pointing device, and the sliding cover may be affected to move. The operation mechanism of the slidable mobile phone is set as follows. When the sliding cover downward slides for a distance, the call function of the slidable mobile phone is automatically interrupted, so that inconvenience of operation is easy to be generated, which makes manufacturers abandon using the pointing device by detecting the pressed direction as the input device of the slidable mobile phone.
Please further refer to FIG. 4. At present, a spring is provided in a common slidable mobile phone and can provide a pull after the sliding cover arrives at a position (such as the turning point of the spring) to make the sliding cover be capable of automatically sliding to position, so that a user does not need to manually pull the sliding cover to a final fixed position. FIG. 4 is a relational graph showing the relationship between relative distances (D) between the main body and the sliding cover of a conventional slidable mobile phone and forces (F) applied by a user. The curve shown in FIG. 4 has an obvious cusp which stands for that an obvious smoothless feel occurs when the user moves the sliding cover, so that it can be known that the conventional slidable mobile phone cannot provide a preferred usage feel.

Please refer to FIG. 5, and FIG. 5 is structural diagram showing a slidable mobile phone 10 of the first embodiment of the invention. In the embodiment, the slidable mobile phone 10 includes a main body 18, a sliding cover 17, a positioning device 13, an upper casing 14 and a lower casing 15. The first combining component 11 includes a first sliding part 111 which is provided at two sides of the first combining component 11. The second combining component 12 includes a second sliding part 121 and a pointing device by detecting the pressed direction 125, wherein the second sliding part 121 is provided at two sides of the second combining component 12 and is U-shaped to cover two sides of the first combining component 11, so that the second sliding part 121 and the first sliding part 111 can be connected to each other and relatively slide. The pointing device by detecting the pressed direction 125 is used for controlling the slidable mobile phone 10 to provide a user with a function of browsing the slidable mobile phone 10. The positioning device 13 includes two magnetic elements 131 and 132, wherein the magnetic element 131 is provided at the first combining component 11, and the magnetic element 132 is provided on the second combining component 12. In the embodiment, the magnetic elements 131 and 132 are both magnets, and the first combining component 11 and the second combining component 12 include containers 112 and 123, respectively. The magnetic element (magnet) 131 is provided in the container 112 and the magnetic element (magnet) 132 is provided in the container 123. In addition, the first combining component 11 includes a front end 113, and the magnetic element 131 provided at the first combining component 11 in the embodiment is located on the front end 113, and the magnetic element 132 provided at the second combining component 12 is provided at a corresponding position. In addition, the magnetic elements (magnets) 131 and 132 can generate magnetic attracting force between them, and the pointing device by detecting the pressed direction 125 in the embodiment is a joystick.
In addition, the main body 11 in the embodiment further includes a spring 16 which is used to connect the first combining component 11 and the second combining component 12, and when the sliding cover 17 slides relatively to the main body 18, the spring 16 can provide a pull to make the sliding cover 17 automatically slide to position after the sliding cover 17 arrives a certain position (such as the turning point of the spring), so that a user does not need to manually push the sliding cover 17 to a final fixed position. However, the spring 16 mentioned in the embodiment, which provides semi-automatic efficacy, can be replaced with other equivalence elements.
Please refer to FIG. 6 and FIG. 7. When a user pushes the sliding cover 17 to make the second combining component 12 move to an opening position (which is shown in FIG. 6), the spring 16 can provide a pull to make the second combining component 12 automatically slide to the opening position after the second combining component 12 arrives at a certain position (such as the turning point of the spring). At this time, the magnetic elements 131 and 132 are located at the closest position and generate magnetic attracting force, so that the main body 18 and the sliding cover 17 can be retained at the opening position (a call is usually made at the opening position). If the user wants to utilize the pointing device by detecting the pressed direction 125 to operate the slidable mobile phone 10, the magnetic attracting force provided by the magnetic elements 131 and 132 can ensure that the main body 18 and the sliding cover 17 cannot move, so that the condition that the usage of the pointing device by detecting the pressed direction 125 during a call causes the call to be interrupted can be avoided. Please refer to FIG. 7, and FIG. 7 is a relational graph showing the relationship between the relative distances (D) between the first combining component 11 and the second combining component 12 and forces (F) applied by a user. Compared with the curve shown in FIG. 7, the curve shown in FIG. 4 is relatively smoothless, and when the user applies force to the sliding cover 17 (please refer to FIG. 5 simultaneously), an obvious smoothless feel occurs and causes the push feel to be bad. After the magnetic elements 131 and 132 are further provided, as shown in FIG. 7, the magnetic attracting force of the magnetic elements 131 and 132 changes the relationship curve and makes the relationship curve smoother, so that the smoothless feel is decreased when the user applies the force to the sliding cover 17, and the pull feel is obviously improved.
Second Embodiment
Please refer to FIG. 8, and FIG. 8 is a schematic diagram showing a slidable mobile phone 20 of the second embodiment of the invention.
