MODE FOR CARRYING OUT THE INVENTION

(9) Hereinafter, a main board for POS terminal 100 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, in the drawings, it should be aware that the same components or parts are denoted by the same reference numerals whenever possible. In describing the present invention, a detailed description of related known functions and configurations will be omitted so as not to obscure the subject matter of the present invention.

(10) Referring to FIG. 3 or 4, a main board for POS terminal 100 according to an embodiment of the present invention includes a substrate unit 110 and a rail block unit 150 or 150.

(11) First, the substrate unit 110 will be described. As shown in FIG. 3, the substrate unit 110 is hardware including components such as a basic circuit and a chip set.

(12) On the other hand, an extended substrate unit 111 protruding outward is extended and formed on one side of the substrate unit 110, and a space S is formed on a lower side of the extended substrate unit 111.

(13) At this time, as the hard disk port unit 140 is formed in the horizontal direction on the front upper part of the extended substrate unit 111, the hard disk port unit 140 and the hard disk connection terminal 210 are coupled with each other when the hard disk 200 is located in the space S so that the hard disk 200 may be directly connected to the extended substrate unit 111 in a straight line on the horizontal plane.

(14) Due to this, as the substrate unit 110 and the hard disk 200 are directly connected to each other without a separate cable (not shown), this prevents electrical malfunction caused by the connection of a cable (not shown), and as the transmission speed of high-speed communication increases through direct connection, communication error is reduced and stable system maintenance becomes possible.

(15) Meanwhile, as the USB port 130 is vertically installed on the rear side upper part of the substrate unit 110, a USB terminal (not shown) of an external device may be directly connected to the USB port unit 130 without a separate USB cable (not shown).

(16) Meanwhile, as shown in FIG. 4, a plurality of ports (for example, an input port, an output port, a communication port, and a USB port) for connecting the necessary peripheral devices are formed on the front side upper part of the substrate unit 110 as one-stage port module unit in one-stage arrangement, this improves the space efficiency inside the POS terminal (not shown), and since the thickness of the POS terminal (not shown) is formed to be thin, it is possible to realize a slim design product, and the POS terminal (not shown) may be easily installed and used without any restriction on a desk, a small-sized table, a counter, a counter desk, and the like.

(17) Next, the rail block units 150 and 150 will be described. As shown in FIGS. 5 to 8, the rail block portions 150 and 150 include a moving paths 151 and 151, first engaging protrusions 152 and 152, pressing bar members 153 and 153 and elastic members 154 and 154 as components that guide the horizontal movement of the hard disk 200 and fix the hard disk 200 when the hard disk 200 is coupled to the hard disk port unit 140 in the process of connecting the hard disk 200 to the hard disk port unit 140, which are formed on both sides of the front surface of the extended substrate unit 111 as a pair.

(18) The moving paths 151 and 151 are kinds of recessed grooves having a shape of and in the inner sides of the rail block units 150 and 150 and allow both sides of the hard disk 200 to be inserted and the hard disk 200 to be moved in a sliding manner.

(19) The first engaging protrusions 152 and 152 are components in which a plurality of protrusions are formed on the inner surface of the moving paths 151 and 151 and are coupled with one side of elastic member 154 and 154 to be described later, thereby allowing the elastic members 154 and 154 to be fixed to the inner surface of the moving paths 151 and 151.

(20) The pressing bar members 153 and 153 are components formed in a long rod shape and connected to the elastic members 154 and 154 coupled with the first engaging protrusions 152 and 152 and located within the moving paths 151 and 151 to press both sides of the hard disk 200 whose movement is completed through the moving paths 151 and 151 and include second engaging protrusions 153a and 153a and round contact surface 153b and 153b.

(21) The first engaging protrusions 152 and 152 are components in which a plurality of protrusions are formed on the one side of the pressing bar members 153 and 153, and are coupled with the other side of the elastic members 154 and 154 thereby allowing the pressing bar members 153 and 153 to be resiliently coupled to the moving paths 151 and 151.

(22) The round contact surfaces 153b and 153b are curved surfaces bent from the end parts of the pressing bar members 153 and 153 toward the inner directions of the moving paths 151 and 151, and the round contact surfaces 153b and 153b allow the fore-end parts of both side surfaces of the hard disk 200 to smoothly enter the curved surface without being caught by the end parts of the pressing bar members 153 and 153 in the process of both sides of the hard disk 200 entering the end parts of the moving paths 151 and 151.

(23) The elastic member 154 and 154 are elastic springs disposed between the first engaging protrusion 152 and 152 and the second engaging protrusion 153a and 153a and it is preferable that the elastic members 154 and 154 maintain a tension state when the hard disk 200 is not coupled to the rail block units 150 and 150.

(24) Meanwhile, when the hard disk 200 is coupled to the rail block units 150 and 150, due to the compression force, the elastic members 154 and 154 are gradually shifted to the compressed state, and at this time, even if the elastic members 154 and 154 are gradually compressed, a tensile force is generated corresponding to the compressive force to return to the original tensile state, and the pressing bar members 153 and 153 press both sides of the hard disk 200 due to the tensile force, thereby enabling the hard disk 200 to be fixed to the rail block units 150 and 150.

(25) Therefore, by preventing the hard disk 200 from being easily detached from the hard disk port portion 140, stable mechanical coupling between the extended substrate unit 111 and the hard disk 200 becomes possible.
