  By the way, the demand for downsizing and thinning is becoming more and more demanding for mobile phones, and in mobile phones equipped with SIM cards, an extra space is required for installing a card reader. Ingenuity is required.

  However, in the conventional mobile phone that transports the SIM card into the card reader by the tray, it is necessary to reciprocate the tray at the same height or higher position as the bottom surface of the battery chamber. Is provided at a level higher than the bottom surface of the battery chamber in accordance with the height position of the tray. As a result, the position of the card reader in the housing is shifted upward.

Therefore, there is a problem that it is difficult to make the casing thin in a mobile phone equipped with a SIM card.
