         [0010]    Several definitions that apply throughout this disclosure will now be presented. 
         [0011]    The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
         [0012]    The present disclosure is described in relation to a point of sale (POS) device. 
         [0013]      FIG. 1  and  FIG. 2  illustrate an embodiment of a POS device. The POS device comprises a housing  10 , two displays  20 , a circuit board  30 , and a storage device  40 . 
         [0014]    The housing  10  comprises a main body  11 , a cover  12 , and a plurality of hinges  13 . 
         [0015]    The main body  11  comprises a base board  111 , a first side board  112 , a second side board  114 , an outer board  115 , a top board  116 , and a support board  117 . The first side board  112  and the second side board  114  are connected to two opposite sides of the base board  111 . The outer board  115  is attached to the base board  111 , the first side board  112 , and the second side board  114 . The top board  116  is attached to the first side board  112 , the second side board  114 , and the outer board  115 . The support board  117  is attached to the base board  111 , the top board  116 , the first side board  112 , and the second side board  114 , and is opposite to the outer board  115 . A side of the support board  117  back to the outer board  115 , the base board  111 , the top board  116 , the first side board  112 , and the second board  114  cooperatively define a receiving space  110 . An opening  118  is defined on a middle portion of the support board  117 . Two pairs of fixing pillars  1171  respectively protrude from a top and a bottom of the support board  117 , near the first side board  112 . Each fixing pillar  1171  defines a connecting hole  1173  perpendicular to the support board  117 . A lock  14  is installed on a middle portion of the second side board  114  away from the outer board  115 . A latch  141  is mounted to an inner side of the second side board  114  and connected to the lock  14 . The latch  141  can be controlled by the lock  14  to rotate out of the receiving space  110 . A tab  1161  protrudes from the top board  116  away from the outer board  115 . One of the displays  20  is rotatably installed on the outer board  115 , near the top board  116 . The base board  111 , the first side board  112 , the second board  114 , the outer board  115 , the top board  116 , and the support board  117  cooperatively define a mounting space, for installing a keyboard, a cashbox, and other apparatus. 
         [0016]    The cover  12  comprises a base plate  120 , a first side plate  121 , a second side plate  123 , a top plate  126 , and a mounting bracket  124 . The first side plate  121  and the second side plate  123  perpendicularly extend inward from two opposite sides of the base plate  120 . The top plate  126  protrudes inward from a top edge of the base plate  120  and is attached to the first side plate  121  and the second side plate  123 . A notch  1261  is defined in a middle portion of the top plate  126 . The other display  20  is rotatably installed on the outside of the top of the cover  12  by a connecting bracket  21  extending through the notch  1261  and fixed to the base plate  120 . Two pairs of fixing pillars  1212  respectively protrude from a top and a bottom of the base plate  120 , near the first side plate  121 . Each fixing pillar  1212  defines a connecting hole  1215  perpendicular to the base plate  120 . Two connecting portions  122  protrude from inner sides of the first side plate  121  and the second side plate  123 . 
         [0017]    The mounting bracket  124  comprises a mounting plate  1242  parallel to base plate  120 , two extending plates  1245  extending from two opposite side edges of the mounting plate  1242  toward the base plate  120 , and two fixing plates  1247  respectively extending outward from edges of the extending plates  1245  away from the mounting plate  1242 . The fixing plates  1247  are fixed on the connecting portions  122 , respectively. The base plate  120 , the connecting portions  122 , and the mounting bracket  124  cooperatively define a housing space  127 . The circuit board  30  is received in the housing space  127 , with connectors of the circuit board  30  facing up. A locking hole  1241  is defined in a middle of the fixing plate  1247  near the second side plate  123 . A storage device mounting bracket  1248  is installed on a middle portion of the outer surface of the mounting plate  1242 . The storage device mounting bracket  1248  is U-shaped and defines a top opening receiving groove  1250  (shown in  FIG. 5 ) for receiving the storage device  40 . Two fixing portions  1251  are respectively formed on tops of two opposite sides of the storage device mounting bracket  1248 . The storage device  40  can slide into the receiving groove  1250  and a resilient handle  41  coupled to an end of the storage device  40  can be latched to the fixing portions  1251 . 
         [0018]    Each hinge  13  comprises two fixing blocks  131 . Each fixing block  131  is rotatably connected to a plurality of connecting sheets  132 . The connecting sheets  132  of one fixing block  131  overlap with the connecting sheets  132  of the other fixing block  131 ; and the connecting sheets  132  of the two fixing blocks  131  are rotatably connected to a shaft  135  extending through the connecting sheets  132 . Two fixing sheets  133  respectively extend from a top and a bottom of each fixing block  131 , near the corresponding connecting sheets  132 . Each fixing sheet  133  defines a through hole  134 . 
         [0019]      FIG. 3  illustrates an assembled, isometric view of the POS device of  FIG. 1 . In assembly, one of the fixing blocks  131  of each hinge  13  can be placed into the receiving space  110 , adjacent to the first side board  112 , and between one pair of fixing pillars  1171 . The through holes  134  of the fixing sheets  133  directly face the corresponding connecting holes  1173  of the fixing pillars  1171 . A plurality of fasteners can extend through the through holes  134  to engage in the connecting holes  1173 , fastening the hinges  13  to the main body  11 . Another fixing block  131  of hinges  13  can be placed into the cover  12 , adjacent to the first side plate  121 , and between the corresponding pair of fixing pillars  1212 . The through holes  134  of the fixing sheets  133  directly face the corresponding connecting holes  1215  of the fixing pillars  1212 . A plurality of fasteners can extend through the through holes  134  to engage in the connecting holes  1215 , fastening the hinges  13  to the cover  12 . Then, the cover  12  is rotatably installed to the main body  11 . 
         [0020]      FIG. 4  illustrates an isometric view of the POS device at a working state. Before working, the cover  12  can be rotated to cover the main body  11 . The first side plate  121  can be rotated to attach the first side board  112 , the second side plate  123  can be rotated to attach the second side board  124 , and the tab  1161  of the top board  116  can cover the notch  1261  of the top plate  126 . The lock  14  can be operated to control the latch  141  to extend through then lock with the locking hole  1241  of the cover  12 . Then, the cover  12  is fastened to the main body  11 ; the storage device bracket  1248  extends through the opening  118  to be received between the outer board  115  and the support board  117 . 
         [0021]      FIG. 5  illustrates an isometric view of the POS device in maintenance. During maintenance, the lock  14  can be operated to control the latch  141  to release the locking hole  1241 . The cover  12  can be rotated away from the main body  11 . The handle  41  can be operated to remove the storage device  40  from the receiving groove  1250 . The mounting bracket  124  can be taken down, for further maintenance of the circuit board  30 . 
         [0022]    In another embodiment, each fixing block  131  and the corresponding connecting sheets  132  can be an organic whole.
