Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the utility model relates to an oral cavity CR scanner device, including scanner shell 1 and the tray 2 that is used for placing the formation of image board, hatch door 3 is installed to shell 1 one side, installs drive arrangement in the shell 1 and toward hatch door 3 direction horizontal reciprocating motion's slider, drive arrangement is motor 5, and motor 5 passes through support 6 to be installed in shell 1 bottom. The sliding device is in screw transmission and comprises a screw rod 7 and a sliding block 8 which is sleeved on the screw rod 7 and slides along the screw rod 7, a ball is arranged between the sliding block 8 and the screw rod 7, one end of the screw rod 7 is connected with a rotating shaft of the motor 5, the other end of the screw rod 7 is processed with a baffle 12 used for limiting the sliding block 8, and a supporting plate 11 used for supporting the sliding block 8 is arranged below the screw rod 7. Tray 2 is hollow structure, installs the spring along tray 2 direction of motion in the tray 2, installs the connecting piece in the spring, and connecting piece one end is passed the spring and is connected with hatch door 3, and the other end processing has and is used for the boss of card on the spring, and screw 9 can be chooseed for use to the connecting piece in this embodiment, and screw 9 passes the spring and is connected with hatch door 3's inboard, and the head card of screw 9 is on the spring, and pressure spring 10 is chooseed for use to the spring. Tray 2 is installed on slider 8, and motor 5 connecting screw 7 drives slider 8 and slides, and slider 8 drives tray 2 toward the horizontal reciprocating motion of direction of hatch door 3, and tray 2 passes through screw 9 interconnect with hatch door 3, and pressure spring 10 supports screw 9 in tray 2's inside to through the 5 dynamic motion processes of self compression deformation cooperation motor. A scanner 4 for scanning an imaging plate on the tray 2 is installed in the housing 1, and the scanner 4 is installed on the upper side of the inner wall of the housing 1.
