Furthermore, Fig. 5 is a perspective view of the panel case(130) o f the battery, and Fig. 6A , that of the upper case(120), and Fig. 6B, that of front sectional view of the upper case(120) respectively. The panel base(130) of the battery having the first charging section which battery reaches in good condition stably so that the back side of the battery may be contacted on the lower section, provides the second section, where battery reaches in good condition stably, vertically by a socket type on the upper section is provided, a joint hole(132) projecting in the foreground to the central section for joining with the upper case(120) is included. The first charging section, wherein in case the battery reaches in good condition stably, a pair of battery guides(133) fixing the battery to the left and right is provided at both end sections of a lower section side and in the lower section a fixing terminal (152) and a moving terminal (153) for contacting with a contactor for charging the battery, a transfer shaft(155) as an axis for possible transferring of the terminals, and an adjustment knob(150) for controlling the locations of the terminals are available. Preferably, inside walls(135), wherein a pair of battery guides(133) contacting with the battery is to be formed inclined by a certain taper so that an interval of upper end sections between both inner side walls(l 35) may become narrower than that between lower end sections, it prevents from easy separating of the battery in case the battery reaches in good condition stably. Furthermore, preferably, as shown in Fig. 4, a rubber pad is attached to said inner side walls(135), by which scratching of contacting battery is prevented and at the same time, it may be fixed stably. Furthermore, a pair of battery guides(133) as shown in Fig. 8, of each back end section is connected with a rotator(134) and a spring. As for a long rotator(134) to the left and right, the center section thereof is combined to the panel base of the battery, where both end sections are combined to each battery guides(133) respectively. Thus, when the battery guides(133) are stretched out for reaching in good condition of the battery, both of them are allowed to move with the same interval by a slide type, and the spring connecting the back side end sections of both battery guides is to be fixed stably for the battery guides to suppressing the battery elastically, to the left and right. Fig. 10 shows a fixed terminal (152) and a moving terminal (153) seen from the front side. At the lower end sections of the fixed terminal and the moving terminal, a transfer shaft(155) passes through, and both end sections are fixed to a fixed board of the transfer shaft. The fixed terminal (152) provides a catching chin(157), the moving terminal (153) provides a rack(154) at the lower section, where the rack(154) provides a stopping chin(158) which right end section projects backward. Preferably, said catching chin(157), wherein the side end section of the front side for the lower section of the fixed terminal is so formed that may project in a ^,_ι ' letter shape, said stopping chin(158) is to be so formed that the right end section of the rack(154) may project in a ' -' letter shape. In case an interval with the fixed terminal reaches a specified distance (preferably, 35mm), when the moving terminal is moved by an adjustment knob(150), the stopping chin(158) of the moving terminal as shown in A section of Fig. 10 is suspended and combined to the catching chin (157) of the fixed terminal, said specified interval is maintained to be able to move the moving terminal and the fixed terminal together. Furthermore, the rack(154) is to be so formed that the length thereof may be longer than that of the transfer shaft(155), and both end sections may be bent below the fixed board of the transfer shaft. In such a case, the moving terminal (158) may move freely from the right end section of the transfer shaft (155) to the left end section. Furthermore, the adjustment knob(150) controlling the locations of terminals(152, 153) provides a pinion(151) at the lower end section as shown in Fig. 7. The pinion(151) engages with the rack(154) at the lower end section of the moving terminal to rotate the adjustment knob. Thus, the moving terminal is to be constructed so that locations of the moving terminal may be controlled to the left and right. A motion adjusting the locations so as to contact the terminals (152, 153) on the battery contactors is as follows: At first, turning the adjustment knob, the side wall of the moving terminal is to push the side wall of the fixed terminal to the left, by which the fixed terminal is set to the battery contactor. Thereafter, turning the adjustment knob reversely, the moving terminal only moves to the left and is set to the other contactor of the battery. At this time after use, if the fixed terminal is biased to the left without contacting the battery contactor, moving the moving terminal to the right by turning the adjustment knob clockwise, the fixed terminal is being pulled. For as said, the catching chin (158) of the moving terminal is suspended to be combined maintaining said specified interval(preferably, 35mm, considering the maximum value out of the intervals between the battery contactors of the current mobile phones) to be able to move the moving terminal and the fixed terminal together. Furthermore, said terminals(152, 153), wherein the fixed polarity does not exist, by connecting a circuit section per polarity plate, each polarity of terminals may be automatically set so as to meet the polarity of each contactor of the battery. The construction of the circuit per the polarity plate is well known to the specialists in the technical field to the present invention. Therefore, detailed description thereof is omitted. Referring to Fig.2 and Fig. 5, the second charging section of the battery panel base(130), wherein a long groove(136) is formed horizontally for the battery to reach in good condition vertically, on the lower surface of the groove is provided a charging contact terminal contacted with the contactor of the battery, in the location of upper side walls in the inner section of the groove, for a fixing board(137) for the vertical terminal so as to move is provided, a vertical terminal housing(138) is so mounted that may fully cover the back side of the vertical terminal fixing board(137) and the outer side walls of the groove. Then, the vertical terminal fixing board (137) as shown in Fig. 8 and Fig. 9 connected with the vertical terminal housing(138) and spring is formed so as to be able to move forward and backward elastically, depending on reaching in good condition of the battery, being pushed backward to suppress the battery ,by which various thicknesses of each type of battery may be fixed stably. Furthermore, preferably, a rubber pad having a lot of projections on the inner side walls of the groove (136) may be attached. The projections of said rubber pad as shown in Fig.l l, wherein the end inclines downward, by which structure, in case the battery is inserted in the groove(136) to charge, it reaches in good condition to be inserted smoothly along the direction of the projections, and thereafter, the battery may be fixed stably in the groove. As said second charging section, the socket type charging may be applied to those products manufactured by the Nokia Co. and the like, where mostly the charging contactors are located at the lower section of the battery for the mobile phone. Again, referring Fig. 4, the door cover(140) is connected so that at both upper end sides of the battery panel base(130) may open/close through a cam(141) and a cam pad(131) of the inside of a connecting housing(122). Then, the cam (141) as shown in Fig.4, a chin is provided, by which in case the door cover (140) is closed, the chin suppresses the cam pad(131) to let fall down. Thereby, the upper end section of the battery panel base (131) almost integrated with the cam pad(131) also falls down. Then, the battery panel base does seesaw motion centering around an axis consisting of a connecting hole(132) and a project(121)section and the first charging section of the battery panel base(131)upward. Therefore after reaching the battery in good condition stably and locating the charging terminals (152, 153) on the contactors of the battery followed by closing the door cover(140), the contactors of the battery are to contact the charging terminals(152, 153) as a reaching section in good condition rises upward due to said seesaw motion. Such a construction, wherein in the case of adjusting the locations by moving the terminals(152, 153) without any contacting with the battery, the wear rate of the end section of the terminal is to be reduced and the battery is to be fixed more stably. Additionally, instead of adjusting the contacting terminals (152, 153) manually by controlling said adjusting knob (150), the locations of the charging terminals(152, 153) and the polarities may be set by detecting the locations of the battery charging contactors and the polarities automatically by means of connecting a stepping motor or DC motor or light sensor or image sensor to the contact terminals(152, 153). In such cases, then, the battery reaching in a good condition, detecting automatically whether the battery reaches in good condition and the locations of the charging contactors by the light sensor or image sensor activated by CPU, which data comparing with already available ones (for example, the number of contacting pins, locations etc) relating to the battery stored in EPROM are automatically detected. Thereby, the locations of the charging terminals (152, 153) and the polarities are set automatically by a motor drive (for example, stepping motor or DC motor). The circuit construction for such activation is well known to the specialists in the technical field of the present invention. Therefore, further detailed description is omitted. As described above, the present invention describes referring to a preferable Embodiment of Example. However, it may be understood that the present invention is to be modified or changed so far as the specialists familiar with the technical field are not contrary to the conception and the area of the present invention described in the following claims.
