Description

本発明は、電子機器と、電子機器に装着可能な電源補助装置に関する。   The present invention relates to an electronic device and a power auxiliary device that can be attached to the electronic device.

近年、デジタルカメラ等の撮像装置では、高機能化によって消費電力が増大する傾向にあり、これに伴って、撮像装置に標準的に装填される電池による動作で撮影可能な枚数は少なくなってきている。この問題に対処するために、電池を収容した外付けの電源補助装置をデジタルカメラに装着し、撮影可能枚数を大幅に増大させるという方法を用いるユーザが増えている。   In recent years, in an imaging apparatus such as a digital camera, power consumption tends to increase due to higher functionality, and accordingly, the number of images that can be captured by operation of a battery that is normally loaded in the imaging apparatus is decreasing. Yes. In order to cope with this problem, an increasing number of users use a method in which an external power auxiliary device containing a battery is attached to a digital camera to greatly increase the number of images that can be taken.

また、高級機のデジタルカメラには、縦位置撮影用の操作部材（縦位置撮影用グリップ）が準備されている。電池は縦位置撮影用グリップに収容され、縦位置撮影用グリップは電源補助装置としてデジタルカメラの本体部に取り付けられる。これらの電源補助装置では、一般的には、電池室に、直接、電池を収納する構成が採用されている。   Further, an operation member for vertical position shooting (a grip for vertical position shooting) is prepared for a high-end digital camera. The battery is housed in a vertical position grip, and the vertical position grip is attached to the main body of the digital camera as a power auxiliary device. In these power auxiliary devices, generally, a configuration in which a battery is stored directly in a battery chamber is employed.

これに対して、近年では、電池を電池ホルダに収納した上で、撮像装置や電源補助装置の電池室に電池ホルダを収納する構成が用いられてきている。このような電池ホルダを用いると、電池ホルダの内部構成を変更することで、電池ホルダに乾電池等の一次電池や充電池等の二次電池を適宜選択して収納することが可能になるため、撮像装置や電源補助装置で使用可能な電池の選択性を高めることができる。   On the other hand, in recent years, a configuration has been used in which a battery is housed in a battery chamber of an imaging device or a power auxiliary device after the battery is housed in the battery holder. By using such a battery holder, it becomes possible to appropriately select and store a primary battery such as a dry battery or a secondary battery such as a rechargeable battery in the battery holder by changing the internal configuration of the battery holder. The selectivity of a battery that can be used in the imaging device or the power auxiliary device can be increased.

特に、近年では、二次電池を収納可能な種々の規格の電池パックが提供されており、電池パックと乾電池とを併用することで、使い勝手を向上させている（例えば、特許文献１参照）。また、特許文献１では、電池室を形成する筐体と電池ホルダのそれぞれに、着脱（挿抜）操作を補助するためのガイドレールと溝とを設けることによって、電池室に対する電池ホルダの着脱作業性を快適なものとしている。   In particular, in recent years, battery packs of various standards that can store secondary batteries have been provided, and the usability is improved by using both battery packs and dry batteries (see, for example, Patent Document 1). Moreover, in patent document 1, the attachment / detachment workability | operativity of the battery holder with respect to a battery chamber is provided by providing the guide rail and groove | channel for assisting attachment / detachment (insertion / extraction) operation in each of the housing | casing and battery holder which form a battery chamber. To make it comfortable.

ところで、近年、撮像装置等の電子機器に対しては、小型化を実現しつつ、新たな操作部材の配置が可能な構造の実現が強く要求されており、そのために、電子機器に形成される電池室の省スペース化が求められている。また、電子機器に用いられる電源補助装置についても、持ち運びの利便性を高める等の観点から、小型化に対する要望は強い。そこで、電池の配置を工夫することよって電池室を省スペース化する技術が提案されている（例えば、特許文献２参照）。   By the way, in recent years, there has been a strong demand for electronic devices such as an imaging device to realize a structure capable of arranging a new operation member while realizing a reduction in size. There is a demand for space saving battery rooms. In addition, there is a strong demand for miniaturization of power auxiliary devices used in electronic devices from the viewpoint of improving convenience of carrying. In view of this, a technique has been proposed that saves battery space by devising the arrangement of batteries (see, for example, Patent Document 2).

特開２００８−２５７９４４号公報JP 2008-257944 A 特開２００６−２２０７５９号公報JP 2006-220759 A

しかしながら、電子機器や電源補助装置の電池室及び電池ホルダを省スペース化した場合に、操作部材の配設位置を確保する等のために、特許文献１に記載されているようなガイドレール等を配置する十分なスペースを確保することができない場合がある。ガイドレールが設けられていない電池室と電池ホルダの構造の一例を示す断面図を図９に示す。   However, when space is saved in the battery compartment and battery holder of the electronic device or the power auxiliary device, a guide rail or the like as described in Patent Document 1 is used to secure the position of the operation member. In some cases, it is not possible to secure a sufficient space for placement. FIG. 9 is a cross-sectional view showing an example of the structure of the battery chamber and the battery holder in which no guide rail is provided.

図９に示す電源補助装置９００は、撮像装置に着脱可能な縦位置撮影用グリップである。電池９５１を収容する電池ホルダ９５０は、電源補助装置９００に形成された電池室９０１に対して着脱自在となっている。電池室９０１に対して電池ホルダ９５０を着脱する際に電池ホルダ９５０に矢印Ｆ方向に力が加わって電池ホルダ９５０が傾くと、電池室９０１の開口部Ｅにおいて電池９５１と電池室３０１を形成するフレームとが擦れてしまう。このとき、電池室３０１を形成するフレームには、一般的に高い強度及び硬度を持つ金属部材が用いられるため、電池９５１を被覆する硬度の低い樹脂外装が、電池室３０１を形成するフレームによって損傷してしまう。   A power auxiliary device 900 shown in FIG. 9 is a vertical position photographing grip that can be attached to and detached from the imaging device. A battery holder 950 that houses the battery 951 is detachable from the battery chamber 901 formed in the power auxiliary device 900. When the battery holder 950 is attached to or detached from the battery chamber 901 and a force is applied to the battery holder 950 in the direction of arrow F to tilt the battery holder 950, the battery 951 and the battery chamber 301 are formed in the opening E of the battery chamber 901. The frame rubs. At this time, since a metal member having high strength and hardness is generally used for the frame forming the battery chamber 301, the low-hardness resin sheathing that covers the battery 951 is damaged by the frame forming the battery chamber 301. Resulting in.

本発明は、電池室及び電池ホルダの省スペース化の要求に応えながら、電池ホルダを電池室に対して着脱する際の電池表面の損傷を簡単な構造で防止することができる技術を提供することを目的とする。   The present invention provides a technique capable of preventing damage to the battery surface with a simple structure when the battery holder is attached to and detached from the battery chamber while meeting the demand for space saving of the battery chamber and the battery holder. With the goal.

図７（ｂ）は、電池室３０１に対する電池ホルダ２００の挿抜中に、電池ホルダ２００が本体部１００に対して矢印Ｄ２方向に傾いた状態を示している。本実施形態では、接触部Ｓ２では、電池２０１が電池室３０１を形成する金属製の天井板３０５と接触する前に、電池ホルダ２００の先端壁部２０６が天井板３０５と接触するため、電池２０１と天井板３０５との接触を防止することができる。また、電池室開閉検出ユニット３０２と電池２０１が接触しても、電池室開閉検出ユニット３０２の樹脂製部材の硬度は、電池２０１の被覆部材の硬度以下であるため、電池２０１の被覆部材の摩耗や破損を防止することができる。電池２０２が電池室開閉検出ユニット３０２の樹脂製部材と接触しても、同じ理由から、電池２０２の被覆部材の摩耗や破損を防止することができる。   FIG. 7B shows a state in which the battery holder 200 is inclined in the direction of the arrow D <b> 2 with respect to the main body 100 during the insertion / extraction of the battery holder 200 with respect to the battery chamber 301. In the present embodiment, in the contact portion S2, the front wall 206 of the battery holder 200 contacts the ceiling plate 305 before the battery 201 contacts the metal ceiling plate 305 forming the battery chamber 301. And the ceiling plate 305 can be prevented from contacting each other. Even when the battery chamber open / close detection unit 302 and the battery 201 are in contact with each other, the hardness of the resin member of the battery chamber open / close detection unit 302 is equal to or less than the hardness of the cover member of the battery 201, so And damage can be prevented. Even if the battery 202 comes into contact with the resin member of the battery chamber open / close detection unit 302, it is possible to prevent the covering member of the battery 202 from being worn or damaged for the same reason.

なお、図６に示すように、電池ホルダ２００の先端壁部２０６の上端には、部分的に突起部２０７が形成されている。高さＨ３は、電池ホルダ２００において電池室３０１の底面板３０４と接触する面から突起部２０７の上端までの高さである。このような突起部２０７を設けることにより、先端壁部２０６の高さを全体的に均一にするよりも極めて容易に、高さＨ３の寸法精度を高めることができる。   As shown in FIG. 6, a protrusion 207 is partially formed at the upper end of the tip wall portion 206 of the battery holder 200. The height H3 is a height from the surface of the battery holder 200 that contacts the bottom plate 304 of the battery chamber 301 to the upper end of the protrusion 207. By providing such a protrusion 207, it is possible to increase the dimensional accuracy of the height H3 much more easily than making the height of the tip wall portion 206 uniform.
