However, the thinned battery pack has a mechanical strength that is slightly lower than that of a battery pack having a sufficient thickness, and is not necessarily β 124343.doc 1343687. Therefore, in the conventional charging device, as described above In the case of the battery pack being thinned, the battery pack may be partially or entirely deformed by the battery pack when the battery pack is housed in the battery storage portion of the charger. The battery pack is installed in the wrong direction. However, when the battery pack that is firmly embedded in the battery accommodating portion is taken out, the battery pack is damaged. Therefore, in the conventional charging device, the problem is how to solve the battery as described above in accordance with the thinning of the battery pack. The wrong installation of the group and the problems that arise. Further, in order to cope with the erroneous mounting of the battery pack as described above, it is conceivable to have a margin in the space of the battery accommodating portion of the charger, and a gap is always provided between the battery accommodating portion and the battery pack to avoid erroneously mounted battery packs. Deformation and damage 'in this case', even if the battery pack is attached to the battery housing portion in the normal direction, a gap is generated, which may cause contact failure of the terminal. The present invention has been developed in view of the above-described conventional circumstances, and an object thereof is to provide a battery pack including a battery pack and a charger, which is particularly suitable for a thinned battery pack and is housed in a battery pack in a regular direction in a charger. In the case of the battery accommodating portion, the charging device can stably hold the battery pack while maintaining a good charging state, and can prevent deformation and damage caused by erroneous mounting of the battery. (Technical means for solving the problem) The charging device of the present invention has the following configuration: the charging device is composed of a flat battery pack including a secondary battery and a charger for accommodating the flat concave battery storage portion of the battery pack, and The battery pack includes a terminal plate having a terminal at one end portion I24343.doc 1343687 and a bottom plate at the other end portion, and a side surface portion which is an outer side when the battery storage portion is housed in a normal direction at the both end portions of the terminal plate (4) The end portion of the end angle is 'and has a recessed corner on the back side. The battery accommodating portion of the charging memory Is includes a contact portion corresponding to the terminal of the battery pack and a protruding portion on the contact side of the storage space partially covering the battery accommodating portion, and is provided on the back surface of the protruding portion.

Further, the charging device is in contact with the battery housing portion Η, and the battery pack B is reversed and stored, that is, when the erroneous mounting is performed, the contacts 9a to 9c of the charger c are not in contact with the terminals 2a to 2c of the battery pack B, and As shown in Fig. 7, the recessed portions 5, 5 on the back side of the both end portions of the terminal block 2 correspond to the convex portions 丨i, 11 of the projecting portion 1 因此 Therefore, the convex portions 11 and 11 of the charging device are not restrained. In the battery accommodating portion, the battery pack B has a margin in the thickness direction (up and down direction) of the battery pack B, and does not hinder the storage of the battery pack. In particular, in the charging device of the embodiment 124343.doc -12-1343687, since the arc (R) 8c is provided between the side wall 8a of the battery housing portion 与 and the bottom wall 8b, even if it is erroneously mounted, the lower side When the outer end portions 4 and 4 interfere with the circular arc 8c and the battery pack B is displaced upward on the side of the terminal block 2, even if the battery pack B is erroneously mounted, the battery pack B cannot be firmly inserted into the battery housing portion. It can prevent deformation and damage of battery pack B. Further, in the charging device, since the battery pack is clamped at both end portions of the bottom plate 3, the recessed portion 5 in a state of being chamfered by the arc (R) is provided on both the front side and the back side, even if the front and rear directions of the battery pack are reversed' When the bottom plate 3 is erroneously attached to the battery accommodating portion Η, as shown in FIG. 8, it is not affected by the front and back of the battery pack β, and the convex portions 11 and 11 are not restrained and the battery is not hindered. The mounting of the stack is not performed to firmly insert the battery pack into the battery compartment, and as a result, deformation and damage of the stack can be prevented. Thus, the charging device described in the above embodiment is provided with the outer end portion 4 and the recess portion 5 at both end portions of the terminal block 2 by the battery pack, and on the back side of the extension portion 1 of the charger C. There is a convex portion , 〗 〖, at this time, the size of the convex portion 控制 is controlled within the range of the angle after the recessed portion 5 shown in Fig. 6, the wrong battery pack B can be used in other words, in other words, It is possible to avoid the erroneous installation of the battery pack β with the erroneous installation of the battery pack β, and it is possible to more reliably obtain both functions of stably maintaining the function of the battery pack in a normal state and avoiding the function of deformation and destruction of the battery pack B. Further, in such a charging device, generally, a display such as a text or a singular number indicating the correct orientation of the battery pack B, and a charging lamp that lights up during charging are provided, so that even if the battery pack B is erroneously mounted It can also be judged quickly. In addition, it is also possible to set up a mechanism for judging the wrong installation. Moreover, even if the charging device is placed in an erroneously mounted state, the charging device does not have to worry about the contact of the terminals with each other, the deformation and destruction of the battery pack, so that it is said that the trouble can occur in the past. Its use value is extremely high.
另外’本發明之充電裝置之構成並不僅限定於上述實施 型態’構成之細部可適宜地加以變更，例如在有關電池組 之外端部及凹陷部與電池收納部之凸部之構成，雖非不能 設在電池組之端子板之橫側（短邊側）與電池收納部之間， 但此情形，由於電池組與電池收納部之側壁之問會產生凹 陷而會損及所收納之電池組之穩定性，故如上述實施型態 般，採用在電池組之表側設置外端部，在背側設置凹陷部 之構成屬於最佳型態。 另外，該充電裝置之電池組之外端部及凹陷部與電池收 納部之凸部《構成也可充分適用力以電池組與以該電池組 為電源之電子機器之電池收納部之間。 【圖式簡單說明】Further, the configuration of the charging device of the present invention is not limited to the above-described embodiment, and the details of the configuration can be appropriately changed, for example, the configuration of the end portion of the battery pack and the convex portion of the recessed portion and the battery housing portion. It is not possible to be disposed between the lateral side (short side) of the terminal block of the battery pack and the battery receiving portion. However, in this case, the battery may be damaged due to the recess of the side wall of the battery pack and the battery receiving portion. Since the stability of the group is as described above, it is preferable to provide an outer end portion on the front side of the battery pack and a recess portion on the back side. Further, the outer end portion of the battery pack and the convex portion of the battery portion of the charging device and the convex portion of the battery receiving portion can be sufficiently applied between the battery pack and the battery housing portion of the electronic device using the battery pack as a power source.
