M281239 IV. Creation Instructions (1) [Technical Field to which the New Type belongs The creative department provides a card reader with a U s B end card sub-section directly on the printed circuit board, and uses reading to form a special structure, To facilitate memory + positioning in the card reader. [Previous technology] Feng's use of memory cards to store data ’has become the mainstay of various electronic devices. It can be used to read the old card with a card reader, and has a hidden place in people's lives. Guanchuang = = More and more attention is paid to 'users require a wide range of value-added card readers outside Xinguangb, but not for manufacturers; research and meet the needs of consumers outside' to reduce costs and continue to develop The goal of the new product. In the past, the 70 items of card reading items, such as housings, circuit boards, and connections; can be divided into several vigorously ... suspected of 7 operation and integrated circuit components (1C), how to find a way to reduce costs by attacking 4 components , 7 focus. An has become the research of various manufacturers and the structure of the K-transmitter is equipped with a circuit board in the housing, connecting-• ΐ and electricity;: = ;; = is set on the circuit board, this connector: use. The connector is one of the very important components in the card reader.-After the manufacturer purchases it, the connection is "low". Second, the processing cost for the connector to be connected to the circuit board is ^ = Page 5 M281239 Creative Instructions (2) Reduced, so the overall effect of the card reader is improved. In terms of competitiveness

[New content] The main purpose of this card reader is to connect the USB terminal Qiu and the USB connector to a type of memory card that can be directly connected to the terminal on the printed circuit board and connected to the memory card. The terminal is connected with the brush = the current "card reader needs to be printed on the circuit board. The secondary card of this creative card reader is to provide a kind of positioning memory card: 'Profit: upper opening, lower The structure of the opening, the first slot and the second slot is a 10 ', so that the memory card without the R specification can be easily fixed in the card reader. For the detailed description and technical contents of this creation, the drawings are now matched. The description is as follows: [Embodiment] First, please refer to the "Figure i and Figure 2" at the same time: The card reader 1G in this A includes:-upper case u lower case 12 and-printed circuit board 13 The upper and lower shells n, 12 can be combined with each other to form a shell, and the upper and lower shells ^, 12 each have a pair of upper and lower openings 111 and 121, and the The diameter of the upper opening ln is slightly larger than that of the lower opening m, and the upper opening ιη is further formed—may The first slot 112 for inserting the fairy memory card 20, and the lower opening 121 further forms a second slot 122 for inserting the Mmc memory card 30. In addition, the lower case 12 is longer than the upper slot 12. The housing 11 is formed as a protruding portion 123, and the protruding portion 123

The specifications of M281239 Creative Instructions (3) correspond to the specifications that meet USB connectors. The printed circuit board 13 is accommodated in the upper and lower cases 1 丨 and 12 and a USB terminal portion 131 and a memory card terminal portion 132 are provided thereon. The USB terminal portion 1 31 is formed in the One end of the printed circuit board 丨 3 is arranged in the protruding portion 1 2 3, and the memory card terminal section 3 2 is provided on the printed circuit board 1 3 corresponding to the upper and lower openings 丨 1 , 丨 2 1, please refer to "Figure 3" below. The memory card terminal 1 3 2 further includes a first group of conductive terminals 1 3 3, a second group of conductive terminals 丨 3 4 and a positioning spring. Arm 1 3 5, wherein the first group of conductive terminals 1 3 3 and the second group of conductive terminals 1 3 4 are arranged in a wrong configuration relative to each other, and the positioning spring arm 1 3 5 is located in the first group of conductive end hands 133 And the side of the second group of conductive terminals. Also, please refer to "Figures 4A and 4B" together. The original printed circuit board 13 is formed with one end of a USB terminal portion 131, and the width of the end is slightly smaller than the width of the printed circuit board 13, and it also caters to Specifications for USB connector. Please refer to "Figures 5A and 5B" and "Figures 6A and 6B" as shown in the figure. The printed circuit board 3 of this creation can be used with different types of memory cards, such as "Figure 5A and 5B". As shown in Figure 5B ", the printed circuit board 13 is matched with s D • s fe card 2 0. When s D memory card 2 0 through the upper opening 11 1 (please see the figure 1 ), When entering the first slot 112 and stopping at the preset position on the printed circuit / board 13, the positioning spring arm 35 is snapped into the side recess of the Shanmian memory card 20 for the purpose of positioning, At this time, the first group of conductive terminals 133 and the second group of conductive end hands 134 are respectively connected to the terminals of the corresponding SD memory card 20, and the SD memory card 20 and the printed circuit board are completed.

Page 7 M281239 IV. Creation Instructions (4) Link for subsequent card reading procedures. As shown in "Figures 6A and 6B", it is the form that the printed circuit board 13 is matched with the MMC memory card 30. "When the Mmc memory card 3 0 is through the lower opening 1 21 (see Figure 1) 'When entering the second slot 1 2 2 and stopping at the preset position on the printed circuit board 13', the positioning spring arm 135 is pressed against the side of the MMC memory card 30 to achieve the purpose of positioning. The first group of conductive terminals 1 3 3 and the second group of conductive terminals 1 3 4 are respectively connected to the terminals of the corresponding MMC memory card 30. The connection between the C memory card 30 and the printed circuit board 13 is completed. , You can carry out subsequent card reading procedures. In accordance with the above, the structure design of the USB terminal portion 13 on the memory card terminal portion 1 2 is directly formed on the printed circuit 13. In addition to eliminating the need to arrange the connector for printing, the area of the circuit board can quickly reduce the manufacturing cost. purpose. The ones mentioned above are merely the preferred embodiments used in this creation, and are not intended to limit the creator of the silk shovel ^ J 作 贝 施 之 摩 巳 围.
