Description

The present invention relates to a memory card reader for reading data from a memory card.

  A method of storing data using a memory card is widely applied in various electronic devices. The data stored in the memory card is read by a card reader. Therefore, the card reader is a device necessary for data storage and management. A conventional card reader includes a housing, a circuit board, a connector, an IC unit, and the like. Therefore, it is an issue for manufacturers to reduce manufacturing costs for these components.

  A conventional card reader has a circuit board, a connector, and an IC unit in a housing. The connector and IC unit are provided on the circuit board. The connector is used to connect to an electronic device or a memory card to transmit data or read data stored in the memory card. Therefore, the connector is an important part in the card reader.

  When manufacturing a card reader, a conventional connector is usually purchased from a connector manufacturer and welded to a circuit board. Such a manufacturing method is difficult to reduce the manufacturing cost of the card reader. That is, it is difficult to efficiently reduce the cost for purchasing the connector, and it is difficult to reduce the cost for welding the purchased connector to the circuit board. Unless manufacturing costs can be reduced, the competitiveness of products in the card reader market cannot be increased.

  An object of the present invention is to provide a card reading device that reduces the manufacturing cost of the entire device by reducing the cost associated with the connector found in the conventional manufacturing method.

Therefore, as a result of intensive research in view of the disadvantages found in the prior art, the present inventor has constructed an upper housing formed with an upper opening, and the upper housing is combined with the upper housing, and corresponds to the upper opening. A lower housing formed with a lower opening, a USB terminal provided in the housing and provided at one end, and a memory card terminal provided at a position corresponding to the upper opening and the lower opening The present invention has been completed on the basis of such knowledge, with the aim of solving the problem by the structure of a memory card reader comprising a printed circuit board including a portion.

The present invention will be specifically described below.
The memory card reading device according to claim 1, an upper housing formed with an upper opening;

A USB terminal portion provided in the housing constituted by the upper housing and the lower housing and provided at one end, and a memory card terminal portion provided at a position corresponding to the upper opening and the lower opening. With such a configuration, the area for providing the connector on the printed circuit board can be saved, and the object of reducing the manufacturing cost can be achieved.

According to a second aspect of the present invention, in the memory card reader, the lower housing according to the first aspect is formed longer than the upper housing, a protrusion is formed at one end, and the USB terminal is provided in the protrusion.

According to a third aspect of the present invention, there is provided the memory card reading device according to the first aspect, wherein the memory card terminal portion includes a first conductive terminal set, a second conductive terminal set provided alternately with the first conductive terminal set, and the first A memory further including a conductive terminal set and a positioning elastic arm provided on a side surface of the second conductive terminal set, the memory being inserted into the printed circuit board via the first conductive terminal set and the second conductive terminal set The card is connected to the memory card and the memory card to be inserted is positioned by the elastic arm.

In the memory card reading device according to the fourth aspect, the specification of the protruding portion according to the second aspect corresponds to the USB connector standard.

In the memory card reading device according to the fifth aspect, the inner diameter of the upper opening in the first aspect is slightly larger than the lower opening.

The memory card reader according to claim 11 forms a first slot into which the SD memory card is inserted in the upper opening of claim 1.

The memory card reader according to claim 17 forms a second slot into which the MMC memory card is inserted in the lower opening of claim 1.

The card reader according to the present invention has an effect that the manufacturing area can be greatly reduced by omitting the area where the connector is provided on the printed circuit board.

The present invention provides a reading device for a memory card, comprising an upper housing formed with an upper opening, a lower opening corresponding to the upper opening, and a housing combined with the upper housing. A USB terminal portion provided at one end of the lower housing, the upper housing and the lower opening, and a position corresponding to the upper opening and the lower opening. The printed circuit board is provided with a memory card terminal portion to be provided, and the object of reducing the manufacturing cost of the entire apparatus is realized by reducing the cost of the connector.
The memory card reading apparatus having such a configuration will be described in detail below with reference to the drawings with specific examples for explaining the structure and features thereof.

  As shown in FIGS. 1 and 2, the card reader 10 according to the present invention includes an upper housing 11, a lower housing 12, and a printed circuit board 13, and the upper housing 11 and the lower housing 12 are combined. Configure the housing. Further, the upper housing 11 and the lower housing 12 form an upper opening 111 and a lower opening 121 at positions corresponding to each other in the vertical direction. The inner diameter of the upper opening 111 is slightly larger than that of the lower opening 121. A first slot for inserting the SD memory card 20 is further formed in the upper opening 111, and a second slot for inserting the MMC memory card 30 is formed in the lower opening 121.

Further, the lower housing 12 is longer than the upper housing 11 to form a protruding portion 123. The specifications of the protrusion 123 are matched to the USB connector standard.

The printed circuit board 13 is provided in a housing constituted by the upper housing 11 and the lower housing 12. A USB terminal 131 and a memory card terminal 132 are provided on the printed circuit board 13. The USB terminal portion 131 is provided in the protruding portion 123 at one end of the printed circuit board 13 corresponding to the protruding portion 123 of the lower housing 12, and the memory card terminal portion 132 is formed in the upper opening 111 and the lower opening 121 of the printed circuit board 13. Provide in the corresponding position.

  As disclosed in FIG. 3, the memory card terminal portion 132 further includes a first conductive terminal set 133, a second conductive terminal set 134, and a positioning elastic arm 135. The first conductive terminal sets 133 and the second conductive terminal sets 134 are provided alternately, and the elastic arms 135 are provided on the side surfaces of the first conductive terminal set 135 and the second conductive terminal set 134.

  As disclosed in FIGS. 4A and 4B, the printed circuit board 13 is formed with one end of the USB terminal portion 131 that is slightly narrower than the width of the printed circuit board 13 and adapted to the use of the USB connector.
