Accordingly, when the motor 61 is driven, the guide block 82, 92 may ascend or descend along the guide shaft 81, 91. The guide block 82, 92 and the guide shaft 81, 91 can reduce the left-right distortion (e.g., the left-right tilt or left-right movement) of the ascending or descending plate 14. Meanwhile, for example, the first guide shaft 81 and the first guide block 82 may be symmetrical with the second guide shaft 91 and the second guide block 92 with respect to the lead screw 61e.

A first guide bushing 82c, 82d may be inserted and fixed to between the first front guide block 82a and the first rear guide block 82b (see FIG. 15).

Accordingly, the guide block 82, 92 can perform linear reciprocating motion more stably along the guide shaft 81, 91. The guide block 82, 92 and the guide shaft 81, 91 can minimize the left-right distortion (e.g., the left-right tilt or left-right movement) of the ascending or descending plate 14.

Referring to FIG. 14, when the rotating shaft of the motor 61 rotates in a first rotation direction, the slider 63 may ascend along the lead screw 61e.

The second elastic member 93 may extend in the vertical direction. The second elastic member 93 may be stretched or compressed in the vertical direction. For example, the second elastic member 93 may be a spring. The second elastic member 93 may be located between the second lower stopper 94, 94a and the second upper stopper 95, 95a, and may be coupled or fixed to the second lower stopper 94, 94a and the second upper stopper 95, 95a.

The second lower stopper 94, 94a may include a second lower insertion portion 94 and a second lower pin 94a. The second lower insertion portion 94 may be inserted into the second groove 920g and may have a cylindrical shape. The outer diameter of the second lower insertion portion 94 may be substantially the same as the inner diameter of the second groove 920g. The second lower pin 94a may extend from the lower end of the second lower insertion portion 94 toward the second bottom protrusion 96a and may have a cylindrical shape. The outer diameter of the second lower pin 94a may be smaller than the outer diameter of the second lower insertion portion 94. For example, the second lower insertion portion 94 and the second lower pin 94a may be formed as one body. For example, the upper side of the second lower stopper 94, 94a may be open while the lower side may be blocked.

A second lower rib 922 may protrude from the lower end of the second groove 920g toward the second lower pin 94a and may extend along the outer circumference of the second lower pin 94a. In the vertical direction, the second lower rib 922 may overlap with a step between the second lower insertion portion 94 and the second lower pin 94a. That is, the second lower rib 922 may restrict the downward movement of the second lower stopper 94, 94a.

The second upper stopper 95, 95a may include a second upper insertion portion 95 and a second upper pin 95a. The second upper insertion portion 95 may be inserted into the second groove 920g and may have a cylindrical shape. The outer diameter of the second upper insertion portion 95 may be substantially the same as the inner diameter of the second groove 920g.

Referring to the left drawing of FIG. 17, the second lower pin 94a may be spaced upward from the second bottom protrusion 96a. At this time, due to the elastic force of the second elastic member 93, the second lower stopper 94, 94a may be caught on the second lower rib 922, and the second upper stopper 95, 95a may be caught on the second upper rib 921. The gap between the second upper stopper 95, 95a and the second lower stopper 94, 94a may be L20, and the gap between the step of the second upper stopper 95, 95a and the step of the second lower stopper 94, 94a may be L10.

Referring to the right drawing of FIG. 17, in response to the descending of the second guide block 92, the second lower pin 94a may be in contact with the second bottom protrusion 96a. At this time, the second elastic member 93 can be compressed, and the second lower stopper 94, 94a can ascend upward within the second groove 920g. The gap L21 between the second upper stopper 95, 95a and the second lower stopper 94, 94a may be smaller than L20, and the gap L11 between the step of the second upper stopper 95, 95a and the step of the second lower stopper 94, 94a may be smaller than L10.

In addition, the outer diameter of the second bottom protrusion 96a may be equal to or smaller than the inner diameter of the second lower rib 922. The second bottom protrusion 96a may be inserted into the second groove 920g in response to the descending of the second guide block 92.

For example, the ascend of the second lower stopper 94, 94a within the second groove 920g can be restricted by contact between the upper end of the second lower insertion portion 94 and the lower end of the second upper insertion portion 95.

For example, the ascend of the second lower stopper 94, 94a within the second groove 920g may be restricted by contact between the lower side of the second guide block 92 and the upper end of the second bottom holder 91a. A second lower cushion 99a may be located between the lower side of the second guide block 92 and the upper end of the second bottom holder 91a, and may be coupled to the upper end of the second bottom holder 91a.

Referring to the left drawing of FIG. 19, the second upper pin 95a may be spaced downward from the second top protrusion 96b. At this time, due to the elastic force of the second elastic member 93, the second upper stopper 95, 95a may be caught on the second upper rib 921, and the second lower stopper 94, 94a may be caught on the second lower rib 922. The gap between the second upper stopper 95, 95a and the second lower stopper 94, 94a may be L20, and the gap between the step of the second upper stopper 95, 95a and the step of the second lower stopper 94, 94a may be L10.

Referring to the right drawing of FIG. 19, in response to the ascend of the second guide block 92, the second upper pin 95a may be in contact with the second top protrusion 96b. At this time, the second elastic member 93 may be compressed, and the second upper stopper 95, 95a may descend downward within the second groove 920g. The gap L22 between the second upper stopper 95, 95a and the second lower stopper 94, 94a may be smaller than L20, and the gap L22 between the step of the second upper stopper 95, 95a and the step of the second lower stopper 94, 94a may be smaller than L10.

Accordingly, the second upper stopper 95, 95a can alleviate the impact at a time when the second guide block 92 and the display unit 10 (see FIG. 15) ascend.

In addition, the outer diameter of the second top protrusion 96b may be equal to or smaller than the inner diameter of the second upper rib 921. The second top protrusion 96b may be inserted into the second groove 920g in response to the ascending of the second guide block 92.

For example, the descending of the second upper stopper 95, 95a within the second groove 920g may be restricted by the contact between the lower end of the second upper insertion portion 95 and the upper end of the second lower insertion portion 94.

For example, the descending of the second upper stopper 95, 95a within the second groove 920g may be restricted by contact between the upper side of the second guide block 92 and the lower end of the second top holder 91b.
