发明名称 MEMORY CARD
摘要 <p>PURPOSE:To improve the operation reliability by providing an upper beam between an upper face opening and an insertion port and providing a lower beam in the vicinity of the insertion port. CONSTITUTION:An upper opening 13 linked to a contact space 14 is formed to an upper face 16 of a printed circuit board 1 and an insertion port 21 linked to the contact space 14 is formed on a side end face 15 of the printed circuit board 1 respectively, an upper beam 11 is formed between the upper opening 13 and an insertion port 21 and a loser beam 12 is formed in the vicinity of the insertion port 21 respectively. In this case, presence of dirt of a terminal part 22 on a printed circuit board 1 is visually confirmed through the upper opening 13 and a foreign material such as dust adhered to the terminal part 22 is removed through the insertion port 21 by blowing at the dust or wiping it out with a cloth or a brush. Moreover, the mechanical strength in the vicinity of the end of the printed circuit board 1 is increased to prevent a bent memory card 1. Thus, the connection between the memory card and the connector is always kept excellent and the reliable operation is more improved.</p>
