• an open side;
• a supporting member mounted to the interior space;
• an upper block comprising a first end portion fixed to the supporting member, formed with an upper tip insertion hole at a second end portion, hinge-engaged with an upper pin mounted to opposing surfaces of the case, and configured to rotate according to an alignment state of an upper tip;
• an upper sensor unit mounted adjacent to the upper block and configured to detect rotation of the upper block;
• a lower block having a first end portion fixed to the supporting member, formed with a lower tip insertion hole at a second end portion, hinge-engaged with a lower pin mounted to opposing surfaces of the case, and configured to rotate according to an alignment state of a lower tip;
• and
