[0001] The utility model relates to the technical field of IC card readers and writers, and more specifically, to a convenient IC card reader and writer. Background Art

[0002] IC card readers and writers are electronic devices specifically used to read and write IC cards. IC cards are widely used in finance, transportation, taxation, social insurance, business administration, medical care, telecommunications, tourism, catering, public utilities, security and other fields due to their large storage capacity, excellent confidentiality, compact size and portability. Therefore, staff often need to carry card readers when working outside.

[0003] Existing IC cards are mainly divided into contact IC cards and contactless IC cards. Contact IC cards are equipped with special contacts, which contact with the corresponding contacts of the read-write device to establish a communication connection. Through this communication connection, recharge information can be written to the chip built into the IC card, and the stored recharge information can also be read from the chip.

[0004] In actual operation, when IC cards must be identified and read by a reader / writer, they often encounter the problem of improper placement, resulting in the IC card contacts not being properly connected to the contacts of the reader / writer. This requires repeated adjustments, which is quite inconvenient to operate. Utility Model Content

[0005] The utility model provides a convenient IC card reading and writing device to solve the problem that when the existing IC card needs to be identified and read by the reading and writing device, it is often placed in the wrong position, and the contacts on the IC card fail to connect with the contacts of the reading and writing device, which requires many adjustments and is very troublesome.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a convenient IC card reading and writing device, comprising a reader / writer body, a display screen provided on the reader / writer body, a card reading area provided on the surface of the reader / writer body, the card reading area being located on one side of the display screen, a positioning plate being movably provided on the top of the card reading area, positioning blocks being movably provided on both sides of the positioning plate, and when the positioning plate moves downward, the two positioning blocks approach each other, which is conducive to enabling the IC card to be read and written quickly and avoiding repeated adjustments.

[0007] In a preferred embodiment, the two positioning blocks are provided with a sloped surface on the opposite side, and guide grooves are provided on both sides of the positioning plate. The positioning blocks are sleeved in the inner cavity of the guide groove, and the sloped surface is slidably connected to the inner wall of the guide groove to facilitate the rapid adjustment of the position of the IC card.

[0008] In a preferred embodiment, a column is fixedly provided on the upper surface of the positioning plate, a support frame is provided on the sliding sleeve outside the column, and the support frame is slidably installed on the upper surface of the card reading area. A first spring is provided between the support frame and the positioning plate so that the positioning plate can automatically reset.

[0009] In a preferred embodiment, a fixing block is fixedly installed on the top of the positioning block, the upper surface of the fixing block is slidably connected to the support frame, and a fixing cylinder is fixedly installed on the opposite side of the two fixed blocks. A fixing sleeve is provided on the external sliding sleeve of the fixing cylinder, and the fixing sleeve is fixedly connected to the inner wall of the support frame. A second spring is jointly provided in the inner cavity of the fixing cylinder and the fixing sleeve so that the slope surface and the guide groove surface can always fit together.

[0010] In a preferred embodiment, a scraper is fixedly mounted on the side of the support frame facing the display screen, and the bottom of the scraper contacts the surface of the card reading area.

[0011] In a preferred embodiment, a third spring is connected to the side of the scraper facing the display screen, and an outer end of the third spring is connected to the inner wall of the card reading area.

[0012] The beneficial effects of the present invention are:

[0013] 1. The utility model sets a positioning plate and a positioning block on the card reading area. When the column is pressed to move the positioning plate downward, the two positioning blocks can automatically approach each other. Therefore, when the lower surface of the positioning plate contacts the IC card, the two positioning blocks will automatically clamp the IC card and ensure that the contacts of the card reading area and the contacts of the IC card are correctly connected, which can effectively avoid the situation where the contacts of the IC card and the contacts of the reading and writing device cannot be correctly connected and need to be repeatedly adjusted.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual Figures 1 to 5 A convenient IC card reading and writing device includes a reader / writer body 1, a display screen 3 is provided on the reader / writer body 1, a card reading area 2 is provided on the surface of the reader / writer body 1, the card reading area 2 is located on one side of the display screen 3, a positioning plate 4 is movably provided on the top of the card reading area 2, and positioning blocks 5 are movably provided on both sides of the positioning plate 4. When the positioning plate 4 moves downward, the two positioning blocks 5 approach each other.

[0023] It should be noted that during the reading and writing process, the IC card is placed on the card reading area 2, and then the positioning plate 4 is pressed downward. The two positioning blocks 5 will automatically approach each other. When the lower surface of the positioning plate 4 contacts the IC card, the two positioning blocks 5 will automatically clamp the IC card and center it, ensuring that the contacts of the card reading area 2 and the contacts of the IC card are correctly docked, which can effectively avoid the situation where the contacts of the IC card and the contacts of the reading and writing device cannot be correctly docked and need to be repeatedly adjusted.

[0024] Furthermore, the two positioning blocks 5 are provided with a slope surface 54 on the opposite side, and the positioning plate 4 is provided with a guide groove 41 on both sides. The positioning blocks 5 are sleeved in the inner cavity of the guide groove 41, and the slope surface 54 is slidably connected to the inner wall of the guide groove 41.

[0025] In the above embodiment, when the positioning plate 4 moves downward, since the slope surface 54 is sloped, the guide groove 41 will contact and slide along the slope of the slope surface 54. During this process, the guide groove 41 will push the positioning block 5, so that the two positioning blocks 5 gradually approach each other during the downward movement of the positioning plate 4.

[0026] Furthermore, a column 7 is fixedly provided on the upper surface of the positioning plate 4 , a support frame 6 is slidingly sleeved on the outside of the column 7 , and the support frame 6 is slidably installed on the upper surface of the card reading area 2 , and a first spring 71 is provided between the support frame 6 and the positioning plate 4 .

[0027] In the above embodiment, when the column 7 is pressed, the positioning plate 4 can be moved downward, and after the column 7 is released, the positioning plate 4 will automatically return to its original position through the first spring 71 .

[0028] Furthermore, a fixing block 51 is fixedly installed on the top of the positioning block 5, and the upper surface of the fixing block 51 is slidably connected to the support frame 6. A fixing cylinder 52 is fixedly installed on the opposite side of the two fixing blocks 51. A fixing sleeve 53 is provided on the outer sliding sleeve of the fixing cylinder 52. The fixing sleeve 53 is fixedly connected to the inner wall of the support frame 6. A second spring 55 is commonly provided in the inner cavity of the fixing cylinder 52 and the fixing sleeve 53.

[0029] In the above embodiment, after the positioning plate 4 is reset, the second spring 55 contracts to reset the fixing block 51 , so that the slope surface 54 is always in contact with the guide groove 41 .

[0030] Furthermore, a scraper 9 is fixedly mounted on the side of the support frame 6 facing the display screen 3 , and the bottom of the scraper 9 contacts the surface of the card reading area 2 .

[0031] In the above embodiment, when the support frame 6 is moved, the scraper 9 can be driven to move, and the scraper 9 contacts the upper surface of the card reading area 2 to facilitate cleaning the surface of the card reading area 2 and reduce the docking error between the contacts of the card reading area 2 and the contacts of the IC card.

[0032] Furthermore, a third spring 8 is connected to the side of the scraper 9 facing the display screen 3 , and an outer end of the third spring 8 is connected to the inner wall of the card reading area 2 .

[0033] In the above embodiment, the support frame 6 is kept in the reset position by the third spring 8 in the normal state.

[0034] Working principle: When the device is in use, the IC card is first placed on the card reading area 2, and then the cylinder 7 is pressed downward, so that the positioning plate 4 can be driven to move downward. During the downward movement of the positioning plate 4, since the slope surface 54 is sloped, the guide groove 41 will contact and slide along the slope of the slope surface 54. During this process, the guide groove 41 will push the positioning block 5, so that the two positioning blocks 5 gradually approach each other during the downward movement of the positioning plate 4. When the lower surface of the positioning plate 4 contacts the IC card, the two positioning blocks 5 automatically clamp the IC card to the center, ensuring that the contacts of the card reading area 2 and the contacts of the IC card are correctly docked, so that the IC card can be quickly read and written through the card reading area 2, avoiding the need for repeated adjustment. After the reading and writing are completed, the cylinder 7 is released, and the positioning plate 4 will automatically reset by the first spring 71. At the same time, the second spring 55 contracts, which will reset the fixing block 51, so that the slope surface 54 is always in contact with the guide groove 41.

[0035] When the surface of the card reading area 2 needs to be cleaned, pushing the support frame 6 can drive the scraper 9 to move. The surface of the card reading area 2 can be cleaned by utilizing the contact between the scraper 9 and the upper surface of the card reading area 2, thereby avoiding the accumulation of dust and debris on the upper surface of the card reading area 2 and reducing the docking error between the contacts of the card reading area 2 and the contacts of the IC card.

[0036] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
