## Abstract

The present invention has advantages in that as a USB port unit and a hard disk port unit are formed on the edge of the substrate unit thereby allowing external USB and external disks to be directly connected to the main board, so that it prevents electrical malfunction caused by cable connection, and as the transmission speed of high-speed communication increases through direct connection, it is to provide a main board for POS terminal which may maintain stable system by reducing communication errors.

## Claims

### Claim 1

A main board for POS terminal 100 built in a POS terminal (not shown), the main board for POS terminal comprising:
a substrate unit 110; and
a one-stage port module unit 120 formed on a front side upper part of the substrate unit 110 and having a plurality of ports for connecting peripheral devices in one-stage arrangement,

### Claim 2 (depends on 1)

The main board for POS terminal 100 of claim 1, wherein a USB port unit 130 installed in a vertical direction is further formed on a rear side upper part of the substrate unit 110.

### Claim 3 (depends on 1)

The main board for POS terminal 100 of claim 1, wherein an extended substrate unit 111 protruding outward is extended and formed on one side of the substrate unit 110, and a hard disk port unit 140 installed in a horizontal direction is further formed on a front side upper part of the extended substrate unit 111.

### Claim 4 (depends on 3)

The main board for POS terminal 100 of claim 3, wherein rail block units 150 and 150′ for guiding a horizontal movement of the hard disk 200 and fixing the hard disk 200 when the hard disk 200 is coupled to the hard disk port unit 140 are respectively formed on both sides of a front surface of the extended substrate unit 111 in a process of connecting the hard disk 200 to the hard disk port unit 140.

### Claim 5 (depends on 4)

The main board for POS terminal 100 of claim 4, wherein in each of the rail block units 150 and 150′, moving paths 151 and 151′ in which parts of both sides M and M′ of the hard disk 200 are inserted are formed on an inner side, and a plurality of first engaging protrusions 152 and 152′ are formed on inner sides of the moving paths 151 and 151′, and a plurality of second engaging protrusions 153a and 153a′ are provided in the moving paths 151 and 151′ and are formed on one sides thereof, and pressing bar members 153 and 153′ where round contact surfaces 153b and 153b′ are bent in inner directions of the moving paths 151 and 151′ are provided on the end part, and elastic members 154 and 154′ in a tension state are provided between the first engaging protrusions 152 and 152′ and the second engaging protrusions 153a and 153a′.
