Description

  The present invention relates to an detachable external recording medium and an electronic apparatus in which a battery is configured adjacently in order to realize a reduction in size and thickness in an image pickup apparatus that captures an image, and in particular, an electronic apparatus having a battery holding mechanism. It is about.

  Conventionally, an imaging apparatus such as a digital still camera has a lens barrel having an optical system, a removable external recording medium, and a battery. Many batteries that can be used repeatedly by charging like an lithium battery are used for the imaging device. It is known that this battery expands thermally when charging and discharging are repeated. For this reason, a space assuming thermal expansion is provided in the battery chamber into which the battery is inserted, and the battery is easily rattled. If there is backlash, the contact pressure between the battery terminal portion and the battery contact portion may become unstable. For example, when an impact such as dropping is applied, if the battery moves violently in the battery chamber, the contact state may become unstable momentarily, the power supply voltage may drop, and normal operation may not be possible and the power may be turned off. is there. Japanese Patent Application Laid-Open No. H10-228561 discloses a battery that reduces the backlash of the battery.

  In addition, there is a demand for a compact and thin imaging device main body, and there is a need for the above-described components arranged so that the imaging device main body is small and thin. For example, by moving the external recording medium slot toward the lens barrel side, it is possible to further reduce the size in the width direction of the imaging apparatus.
