Description

  The present invention relates to a television receiver equipped with a memory card slot.

  In recent years, miniaturized recording media such as SD memory cards and multimedia cards have started to spread, and it has become convenient to carry and store, and it has become possible to easily record and reproduce program broadcasts. On the other hand, downsizing leads to the possibility of swallowing by mistake when an infant or child takes it to the mouth. For example, the size of the SD memory card is 24 mm × 32 mm × 2.1 mm, and the size that an infant can swallow is 32 mm in diameter and 57 mm in length. SD memory cards are within that range, and infants can get in their mouths and accidentally swallow them. Also, there are many cases where SD memory cards are always attached to electronic devices such as TVs, including forgetting to remove them, and they can be easily ejected by simply pushing them out or simply opening the lid and pulling. Infants who can put anything in their mouth can easily swallow.
