Electronic apparatus and housing unit that are equipped with housing member

#The present invention relates to a housing unit and an electronic apparatus that are equipped with a housing member into which a memory card or the like is to be inserted.

#If a frequency for transmitting various signals is increased in an electronic apparatus, high-frequency electromagnetic waves tend to radiate to the outside. For example, in an electronic apparatus with a card slot, in a case where a metallic component is placed close to the card slot which a recording medium such as a memory card can be inserted into and removed from, noise generated in the card slot propagates to an area to which the noise tends to radiate due to electromagnetic coupling with the metallic component. If the noise that has propagated in the electronic apparatus radiates to the outside using a cable or the like, which is connected to the electronic apparatus, as an antenna, it may become difficult to meet noise radiation levels complying with international standards.

#The shorter the distance between the card slot and a conductive component such as a metallic component is, and the larger the area in which they face each other is, the higher the noise that propagates through the conductive component becomes. Therefore, anti-EMI (Electro Magnetic Interference) measures are matters to be considered particularly for small electronic apparatuses whose components are short distances apart.

#FIGS. 1A and 1B are a perspective view and an exploded perspective view, respectively, showing an internal construction of an image pickup apparatus according to a first embodiment.

#FIG. 2 is a front view of a card slot.

#FIG. 3 is a front view showing a state in which the card slot and a grounding assisting member are mounted on a printed circuit board according to the first embodiment.

#Embodiments of the present invention will now be described in detail with reference to the drawings. Here, an image pickup apparatus (specifically a digital camera) is taken as an example of an electronic apparatus according to the present invention, but the electronic apparatus according to the present invention is not limited to an image pickup apparatus.

#FIG. 1A is a perspective view showing an internal construction of an image pickup apparatus according to a first embodiment. FIG. 1B is an exploded perspective view of the image pickup apparatus according to the first embodiment. It should be noted that FIGS. 1A and 1B show only elements (components) related to the present invention, and description of elements other than the elements (components) related to the present invention is omitted.

#The image pickup apparatus has a printed circuit board 1, a card slot 2, a grounding assisting member 3 (a metal sheet member), and a chassis 4. The printed circuit board 1, the card slot 2, and the grounding assisting member 3 make up a card slot unit (housing unit).
