In this embodiment, the holder 26 has a structure in which in the condition where the first plate portion 28 shuts off the second opening 20, the surface of the first plate portion 28 is flush with the side surface 1808 in the periphery of the second opening 20, while an end portion of the first plate portion 28 fronts on the first opening 15, the end portion of the first plate portion 28 fronting on the first opening 15 is provided with a groove 2802 in which a hooking means such as a minus screw driver is locked, and, further, the end portion of the first plate portion 28 fronting on the first opening 15 is provided with an inclined surface 2804 for guiding the hooking means into the groove 2802.
Besides, in this embodiment, as shown in FIG. 8, an engaging portion 3006 is provided at a portion, in the vicinity of the first plate portion 28, of the peripheral wall 3002, and the engaging portion 3006 is engaged with and disengaged from an engaging portion (not shown) provided at a position in the vicinity of the second opening 20. In addition, as shown in FIG. 9, the peripheral wall 3002 is provided with two lock pawls 3008 for preventing the slip-off of the secondary battery 140 mounted in the holder 26.
The first opening 15, the battery containing chamber 14, and the second opening 20 are formed in such sizes that the holder 26 with the secondary battery 140 mounted therein can be moved from the component part containing space 24 to the exterior of the case 102.
Now, assemblage of the image pickup apparatus 10 will be described below.
FIG. 8 illustrates the assemblage of the secondary battery 140 and the holder 26, FIG. 9 illustrates the condition where the secondary battery 140 and the holder 26 are mounted in position, and FIG. 10 illustrates the condition where the secondary battery 140 and the holder 26 are contained in the containing space 24.
First, as shown in FIG. 8, the secondary battery 140 and the flexible substrate 32 are connected to each other.
The flexible substrate 32 is formed in an L shape, and functions to electrically connect the secondary battery 140 and the circuit portions such as the control unit 136 mentioned above to each other. The flexible substrate 32 is provided with connection holes 3202 in one end in the longitudinal direction thereof, and with a connection portion 3204, for connection to a connector on the side of the control unit 136, at the other end in the longitudinal direction thereof. In addition, the flexible substrate 32 is provided with a notch 3206 in an intermediate portion thereof so that the flexible substrate 32 will be easily broken when a stress in the longitudinal direction is exerted thereon.
As shown in FIG. 8, connection terminals 141 formed of conductive material are preliminarily fixed, by spot welding or the like, respectively to electrodes provided on the upper surface and the lower surface of the secondary battery 140, the connection terminals 141 are passed through the connection holes 3202 formed in the flexible substrate 32, the connection terminals 141 are soldered to the connection holes 3202, and the connection portion 3204 of the flexible substrate 32 is connected to the above-mentioned connector.
Next, the holder 26 is inserted into the battery containing chamber 24 through the first opening 15, and the second plate portion 30 of the holder 26 is inserted into the second opening 20. This engages the engaging portion 3006 of the holder 26 with the above-mentioned engaging portion of the side wall 22, whereby the condition where the first plate portion 28 shuts off the second opening 20 is maintained, and, in this condition, the second plate portion 30 of the holder 26 protrudes to the outside of the battery containing chamber 24.
Here, as shown in FIGS. 9 and 10, the secondary battery 140 connected to the flexible substrate 32 is mounted to the second plate portion 30 of the holder 26. In this manner, the secondary battery 140 and the holder 26 are mounted into the housing 103.
Subsequently, the housing 103 in this condition is mounted to the rear side case 102B. This results in that the secondary battery 140 is disposed in the component part containing space 24, together with the holder 26.
Then, the front side case 102A is mounted to the rear side case 102B to thereby assemble the image pickup apparatus 10, whereby the component part containing space 24 for containing the secondary battery 140 is formed between the side wall 22 of the housing 103 and the front side case 102B.
Now, separation of the secondary battery 140 from the image pickup apparatus 10 will be described below.
FIGS. 11A to 11C illustrate an operation of separating the secondary battery 140.
As shown in FIG. 11A, the opening/closing lid 16 is opened to open the first opening 15, and the battery 138 is drawn out from the battery containing chamber 14 to the outside of the case 102.
Next, as shown in FIG. 11B, the tip end of the hooking means 2 such as a minus screw driver is inserted through the guide surface 2804 into the groove 2802, and, in this condition, the hooking means 2 is rotated, whereby the first wall portion 28 is disengaged from the second opening 20, and the holder 26 is moved from the component part containing space 24 into the battery containing chamber 14. In this instance, the engaging portion 3006 of the holder 26 and the above-mentioned engaging portion of the side wall 22 are disengaged from each other.
When the holder 26 is moved from the component part containing space 24 into the battery containing chamber 14, a force in the direction for pulling the flexible substrate 32 is exerted on the flexible substrate 32, whereby the flexible substrate 32 is easily broken, starting from the notch 3206.
Alternatively, even where the notch 3206 shown in FIG. 8 is not provided, since the flexible substrate 32 is folded in a direction orthogonal to the direction for drawing out the battery 140, the movement of the holder 26 causes a twisting force to act on the fold portion of the folding of the flexible substrate 32, whereby the flexible substrate 32 can be easily broken, starting from the fold portion.
When the flexible substrate 32 is broken, the holder 30 and the secondary battery 140 held in the holder 30 are drawn out through the second opening 20 into the battery containing chamber 14, and, further, are taken out from the battery containing chamber 14 to the outside of the case 102 through the first opening 15.
In this manner, the secondary battery 140 is separated from the image pickup apparatus 10.
As has been described above, according to this embodiment, the wall portion 18 defining the battery containing chamber 14 is provided with the second opening 20, the component part containing space 24 communicated with the second opening 20 is provided in the inside of the case 102, the holder 26 is provided which includes the first plate portion 28 detachably attached to the second opening 20 to shut off the second opening 20, and the second plate portion 30 projecting from the first plate portion 28 and extending in the component part containing space 24 in the condition where the first plate portion 28 shuts off the second opening 20, and the secondary battery 140 is held in the holder 26; therefore, the second opening 20 and the holder 26 are not exposed to the outside of the case 102. Accordingly, the appearance quality of the image pickup apparatus 10 is not impaired, and, since the secondary battery 140 can be taken out of the component part containing space 24 together with the holder 26 at the time of discarding the image pickup apparatus 10, the operation of removing the secondary battery 140 can be easily carried out.
In addition, according to this embodiment, an end portion of the first plate portion 28 of the holder 26 fronts on the first opening 20 in the condition where the first plate portion 28 shuts off the second opening 20, and the end portion of the first plate portion fronting on the first opening 20 is provided with the groove 2802 in which the hooking means such as a minus screw driver is locked; therefore, the holder 26 can be taken out of the component part containing space 24 by only engaging the hooking means with the groove 2802 and operating the hooking means, which is advantageous in enhancing the workability in separating the secondary battery 140.
In addition, in this embodiment, the surface of the first plate portion 28 is so formed as to be flush with the side wall 1808 being a wall surface in the periphery of the second opening 20 in the condition where the first plate portion 28 shuts off the second opening 20; therefore, the surface of the first plate portion 28 guides the outside surface of the battery 138 at the time of mounting and dismounting the battery 138 into and from the battery containing chamber 14, which is advantageous for smoothly mounting and dismounting the battery 138.
Besides, in this embodiment, since a partial assembly having the secondary battery 140 connected to the flexible substrate 32 can be preliminarily prepared and the partial assembly can be mounted to the holder 26, efficiency in the operation of mounting the secondary battery 140 and the holder 26 can be enhanced advantageously.
Incidentally, while the configuration in which the first opening 15 is opened and closed by the opening/closing lid 16 has been described in this embodiment, the above-mentioned effects can naturally be displayed even in the case where the opening/closing lid 16 is absent or where the second opening 28 is exposed directly to the appearance surface.
In addition, while the second opening 20 has been provided in one of the two side walls 1808 of the wall portion 18 constituting the battery containing chamber 14 in this embodiment, the portion provided with the second opening 20 may be any one of the other side wall 1808, the front wall 1802, and the back wall 1804.
Besides, while the second opening 20 has been provided in the wall portion 18 of the battery containing chamber 14 in this embodiment, the portion provided with the second opening 20 may be a wall portion constituting the memory containing chamber 12. In addition, where the image pickup apparatus 10 is provided with a chamber for containing an adapter operated by being electrically connected to the electronic apparatus, the second opening 20 may be provided in a wall portion constituting the adapter containing chamber.
Besides, while the notch 3206 has been used for easy breaking of the flexible substrate 32 in this embodiment, a configuration may be adopted in which the notch 3206 is not used and in which a fold portion of the flexible substrate 32 is broken through twisting. Alternatively, for example, the flexible substrate 32 may be provided with a thinned portion. Thus, there can be contemplated a variety of configurations for easy breaking of the flexible substrate 32.
In addition, while the secondary battery 32 and the control unit 136 have been connected by the flexible substrate 32, lead wires may be used in place of the flexible substrate 32. Where the lead wires are used, it suffices to set the strength of the lead wires in such a manner that the lead wires can be broken easily.
Besides, while the case of containing the rectangular plate-like battery 138 in the battery containing chamber 14 has been described in this embodiment, the shape of the battery may be a prism or may be a shape having a curved surface such as a cylinder. In addition, a variety of dry cells may be used in place of the battery 138.
Besides, while the case of separating the secondary battery has been described in this embodiment, the present invention can naturally be applied to the cases of separating any of various electrical component parts such as a primary battery, a flash capacitor, and the like.
In addition, while the image pickup apparatus has been shown as an example of the electronic apparatus in this embodiment, the present invention is applicable to a variety of electronic apparatuses.
INDUSTRIAL APPLICABILITY
According to the present invention, the appearance quality of the electronic apparatus is not impaired, since the second opening and the holder are not exposed to the outside of the case. In addition, since the secondary battery and electrical component parts can be taken out of the component part containing space together with the holder at the time of discarding the electronic apparatus, the operation of removing the secondary battery and the electrical component parts can be carried out easily.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
