And in each main-body part 60 and 60, the position which corresponds to the horizontal direction with respect to the insertion hole 58 is used as a reference | standard, and the support shaft part 63 is axially attached so that it may be located on the upper side, and it arrange | positioned so that it might extend below Three link members 62A, 62C, and 62E and two link members 62B and 62D that are pivotally attached so that the support shaft portion 63 is positioned on the lower side and are arranged to extend upward are alternately positioned. It is arranged to do. In addition, the link members 62 </ b> A to 62 </ b> E have a slider portion 64 rotatably provided at an end portion (the other end) on the opposite side of the support shaft portion 63. The slider portion 64 protrudes in a direction away from the column portion 57 and is moved in the horizontal direction by swinging of the link members 62A to 62E around the support shaft portion 63. A plurality of (four in the present embodiment) switch operation portions 65 project from the slider portion 64 on the surface on which the support shaft portion 63 is located, with a predetermined interval along the moving direction. Further, the link members 62 </ b> A to 62 </ b> E protrude in the horizontal direction at the intermediate position having a predetermined distance from the support shaft portion 63 so as to correspond to the insertion hole 58 in the horizontal direction and come into contact with the key pile of the key. A key clamp portion 66 is provided. In the present embodiment, the key clamp portion 66 is provided so that the height can be adjusted by screwing and fixing a separate plate member to the long groove, and the screwed portion serves as an action point.

  The reading switches 67A to 67E are arranged on the projecting side of the switch operating portion 65 of the slider portion 64 with respect to the main body portions 60 and 60, and are turned on when the switch operating portion 65 abuts. Specifically, the reading switches 67 </ b> A to 67 </ b> E include an elastic piece that protrudes toward the slider portion 64, and the elastic piece bends away from the slider portion 64 by the contact of the switch operation portion 65 to turn on the contact. In this way, a signal is output.

  In the key reading device 55 configured as described above, when the pair of main body portions 60 and 60 move so as to be close to the column portion 57, the key clamp portions 66 of the link members 62A to 62E move the key crest of the key from the left and right. Abut so as to sandwich. And when the main-body parts 60 and 60 move close to a predetermined position, according to the protrusion amount of a key mountain, link member 62A-62E will rock | fluctuate in the direction which leaves | separates by using the spindle part 63 as a fulcrum.
