The present invention relates to an RFID reader that can be mounted to a mobile terminal, and more particularly, a mobile terminal such as a PDA (Personal Digital Assistant) can be mounted and used, as well as having an efficient structure, being portable and easy to operate. The present invention relates to an RFID reader capable of mounting a mobile terminal.

In general, a mobile terminal is a terminal that can be used freely while moving regardless of a place, such as a mobile communication terminal such as a mobile phone, and a personal digital assistant (PDA) called a personal portable terminal. Therefore, the term 'mobile terminal' used herein includes all of these terms, but hereinafter, the description will be limited to a personal digital assistant (PDA) for convenience of description.

In a complex and diversified society, each individual has a need to store and maintain his or her own information, and various products are currently on the market to meet such individual needs. One of them is PDA (Personal digital assistant).

PDA, also known as a pocket computer, is a generic term for a palm-sized device that has a calculation, data storage and retrieval function for personal or business use, and is often used to maintain schedule calendars and address book information.

In particular, industrial personal digital assistants (PDAs) are currently being used mainly in the logistics industry, and the market is gradually expanding.

Industrial PDA is a PDA with a variety of office functions such as barcode scanner, card payment machine, etc., which are not found in general PDA. When using an industrial PDA, it is possible to efficiently carry out delivery, data management and related tasks. For example, insurers can carry out various insurance-related tasks such as customer information management, customer search, schedule management, counseling logbook management, anniversary search, and invoice processing. In hospitals, medical records, medical history, prescriptions, and image images and graphics such as X-rays can be entered and retrieved by an industrial PDA carried by medical personnel without time and place restrictions. The police officers are allowed to work on their mobile phones through industrial PDAs, allowing them to immediately pay the financial institutions the violations of traffic laws that can be paid only 2-3 days after the crackdown. It can dramatically shorten.

On the other hand, RFID (radio frequency identification) is a general term for a technology for processing information of the object using a small semiconductor chip. It is a non-contact recognition system that attaches a small chip to various items and transmits and processes the information of the object and the surrounding environment information at radio frequency.

A radio identification system consisting of a reader with a reading and decoding function, an RF ID tag with built-in information, operating software, and a network, processes information by identifying a thin flat tag attached to an object.

RF tags consist of a semiconductor-made transponder chip and an antenna, which are passive and active. While passives operate by receiving energy from the reader's radio signal without an internal power source, the active has a built-in RF tag cell to operate on its own. It is also classified into a chip tag using a silicon semiconductor chip and a chipless tag composed only of an LC device, a plastic or a polymer device.

Radio frequency identification does not require direct contact or scanning in the visible band as a bar code. Because of these advantages, it is evaluated as a technology to replace the bar code, and the range of application is expanding. Low frequency radio frequency identification systems (30 kHz to 500 kHz) are used at short distances of less than 1.8 m, while high frequency systems (850 MHz to 950 MHz or 2.4 GHz to 2.5 GHz) are known to be able to transmit over a distance of 27 m or more.

This RFID technology enables various management systems such as process management, asset management, logistics management, inventory management, access compensation, location tracking, and cultural property management to be more conveniently performed. Research is actively underway and a variety of products are already on the market. RFID readers on the market range from portable RFID readers with built-in functions to industrial PDAs to fixed RFID readers that are fixed to a table, and the scope of their application is expanding.

However, when the function of the RFID reader is embedded in the PDA, the size of the PDA may actually be huge, which may be somewhat inconvenient for a user who wants to use only a simple PDA function. On the contrary, in the case of a fixed RFID reader, it is difficult to use other than a limited place because it is not portable.

Therefore, considering that PDAs are widely used throughout the industry, if a separate RFID reader that can be used with a PDA is developed, it is expected that various management systems through the RFID reader can be more effectively performed when necessary.

The rocker 74 is coupled to the rocker coupling portion 28 formed on the upper surface of the upper plate 20. The rocker 74, the body portion 75 is disposed in the space between the upper plate 20 and the pocket portion 60, and extends downward from one side of the body portion 75, the end of the upper plate 20 Exposed to the bottom of the upper plate 20 through the through hole (20a) formed in the plate surface of the pressing button portion 76 to operate the rocker 74, and extends upward from both sides of the upper surface of the body portion 75 and the end is A pair of hook hooks 77 which are exposed through a pair of locking slots 72 and are selectively locked to and released from the catching jaw 1a (see FIGS. 3 and 11) formed on the bottom of the PDA 1; And a rotation shaft portion 78 formed on the pressing button portion 76 to form a rotation axis of the rocker 74.

The body portion 75 is a portion that integrally supports the pressing button portion 76 and the pair of hooking hook portions 77 to form an approximately partially angled half moon shape. However, the scope of the present invention is not limited thereto.

The pressing button portion 76 is a portion that substantially drives the rocker 74. That is, the user can separate the PDA 1 from the pocket portion 60 by pressing the pressing button portion 76. The pressing button portion 76 is a pair of locking hooks 77 are rotated in the pair of locking slots 72 when pressing the pressing button portion 76 in the plate direction of the upper plate 20. It has an arc shape. The non-slip jaw 76a is further formed on the exposed plate surface of the pressing button portion 76.

The pair of hook hooks 77 are formed to protrude upward from both ends of the body portion 75. As described above, the pair of hook hooks 77 pass through the through holes 20a formed in the plate surface of the upper plate 20 to protrude into the pockets 60 and are formed on the bottom of the PDA 1. (1a, FIG. 3 and FIG. 11) is a component that is selectively engaged and released. At the ends of the pair of hook hooks 77, an inclined surface 77a inclined in the direction in which the PDA 1 is mounted on the pocket 60 is further formed. The inclined surface 77a allows the PDA 1 to be easily mounted in the pocket part 60.

The rotary shaft portion 78 protrudes in opposite directions from both sides of the pressing button portion 76. The rotary shaft portion 78 is accommodated in the shaft receiving portion 28a formed in the rocker coupling portion 28, and then fixed by a separate bolt (not shown) or the like to form the rotary shaft core of the rocker 74.

Between the body portion 75 and the rocker engaging portion 28 of the rocker 74, an elastic member 79 that elastically biases in a direction to return the rocker 74 to its original position when the pressure button 76 is released. Is further provided.

Thus, when the PDA 1 is mounted in the pocket portion 60, as shown in FIG. 11, when the user presses the pressing button portion 76 in the A direction, the rocker 74 is pressed by the pressed force. ) Rotates in one direction with the rotational shaft portion 78 as the axis (from the solid line to the double-dotted line). By the rotation of the rocker 74, the pair of hook hooks 77 can be released from the latching jaw 1a formed on the bottom surface of the PDA 1. Thereafter, when the pressing button portion 76 is released, the rocker 74 is returned to its original state by the elastic repulsive force of the elastic member 79 (in the dashed line in the solid line direction).

As such, the pair of hook hooks 77 may be released from the hooking jaw 1a formed on the bottom surface of the PDA 1 by a simple method of pressing the press button. However, the pressing button should not be pressed accidentally or arbitrarily in the process of using the RFID reader. If the pressing button is arbitrarily pressed, there is a high possibility that the PDA 1 is separated from the pocket portion 60. The stopper 80 is further provided to prevent this.

As shown in FIGS. 8, 10, and 11, the stopper 80 is movably coupled to the upper plate 20 adjacent to the rocker 74 in one direction to selectively restrain the operation of the rocker 74. It plays a role.

The stopper 80 is a stopper body 81 which is selectively disposed on the bottom of the body portion 75 of the rocker 74 to move in the plate surface direction of the upper plate 20, restraining the operation of the rocker 74, And a stopper rod 82 extending downward from the stopper body 81 and exposed through the through hole 20b formed in the bottom surface of the upper plate 20 to operate the stopper body 81.

At this time, the stopper body 81 is further provided with a protrusion 81a that is selectively disposed on the stepped portion 75b formed on the body portion 75 of the rocker 74. Substantially, the protrusion 81a is disposed on the stepped portion 75b to constrain the operation of the rocker 74. For example, as shown in FIG. 11, when the stopper 80 moves in the B direction, as shown by the solid line, when the protrusion 81a is disposed on the stepped portion 75b, the operation of the rocker 74 is stopped. When the stopper 80 is operated by a double-dashed line and the protrusion 81a is separated from the stepped portion 75b, the rocker 74 can be operated.

On the other hand, only the configuration of the locking portion 70 described above is sufficient to lock and unlock the PDA 1 in the pocket portion 60. However, in some cases, the coupling force of the PDA 1 mounted in the pocket part 60 may be somewhat weak.

In order to compensate for this, an elastic protrusion 90 is further provided. The elastic protrusion 90 is coupled to the inner wall surface of the pocket portion 60 and elastically locked to and released from the groove 1b (see FIG. 3) formed on the side surface of the PDA 1. As a result, the elastic protrusion 90 is a means for supporting the PDA 1 in the pocket 60 together with the locking portion 70.

The elastic protrusion 90 is formed on the protrusion supporting plate 91 such that the protrusion supporting plate 91 coupled to the inner wall surface of the pocket 60 and the outer portion except for one side are cut off from the protrusion supporting plate 91. In the projection supporting plate 91, the plate spring cutout 92 and the plate spring cutout 92 which are elastically movable in the horizontal direction in the direction in which the PDA 1 is mounted on the pocket 60 are provided. It is provided with an elastic protrusion 93 is provided to protrude into the inner space of the 60 selectively fitted into the groove portion (1b) formed on the side of the PDA (1).

The elastic protrusions 90 are inserted into the protrusions mounting grooves 60a respectively formed on both inner wall surfaces of the pocket portion 60 facing each other. Of course, since the scope of the present invention is not limited thereto, the elastic protrusion 90 may be integrally formed on the inner wall surface of the pocket 60.

Thus, when the PDA 1 is mounted in the pocket portion 60, the locking jaw 1a formed on the PDA 1 is caught by the locking hook portion 77 of the rocker 74, and at the same time, the PDA 1 The elastic protrusions 93 are fitted into the groove portions 1b formed on the side surfaces thereof. That is, when the PDA 1 is inserted into the pocket portion 60, the leaf spring cutout portion 92 is pushed backward with respect to the protrusion support plate 91, and the groove portion 1b is placed in the elastic protrusion 93 region. When the plate spring-shaped cutout portion 92 is projected to the original state again with respect to the projection support plate 91 will be able to be coupled to the groove (1b).

Briefly describing the operation of the RFID reader having such a configuration as follows.

First, in order to mount the PDA 1 into the pocket portion 60, the PDA 1 is partially pushed into the pocket portion 60 while being accommodated therein. Then, after the rocker 74 is pushed in one direction with the axis of rotation 78 as the axis, the pair of hook hooks 77 finally catches the hooking jaw 1a formed on the bottom surface of the PDA 1. At the same time, the leaf spring-shaped cutout portion 92 pushed backward with respect to the projection support plate 91 protrudes forward again, so that the elastic protrusion 93 can be coupled to the groove portion 1b formed on the side of the PDA 1. do.

In this state, the user grasps the holding part 35 and then arranges the RFID reading part 40 adjacent to the RFID tag (see FIG. 4) to be read. Then, pressing the pressing button portion 38b of the switching unit 38 with one finger. Then, the pressing button portion 38b is rotated based on the pivot shaft 38a to operate the module operation portion 38c to operate the RFID module 42 to read information in the RFID tag to be read. The read result is transmitted to the auxiliary PCB 44 through the main PCB 43, and then output to the screen of the PDA 1 through the connection terminal unit 63 and stored therein. Through this series of processes, various management systems can be implemented.

When the use is complete, as shown in FIG. 11 to separate the PDA 1, the pressing button portion 76 is pressed in the A direction. Then, the rocker 74 rotates in one direction with the rotation shaft 78 as an axis by the pressurized force (solid line to double chain line direction). By the rotation of the rocker 74, the pair of hook hooks 77 can be released from the latching jaw 1a formed on the bottom surface of the PDA 1. In this state, the PDA 1 may be removed from the pocket part 60. Subsequently, when the pressurizing button portion 76 that has been pressed is released, the rocker 74 returns to its original state by the elastic repulsive force of the elastic member 79 (in the dashed line in the solid line direction).

As such, according to the present embodiment, a mobile terminal such as a personal digital assistant (PDA) 1 may be mounted and used, as well as having an efficient structure, being portable and simple in operation. Therefore, it is possible to perform various management systems anytime and anywhere more effectively.
