Electronic Indicating Instrument

Abstract

To obtain an electronic formula indicating instrument which can be attached to disk without entering into an inner part of the disk and can accept a panel with a different thickness.SOLUTION: An electronic formula indicating instrument 1 is an electronic formula indicating instrument that is attached to a disk in a state where one part is inserted into an inner part of the disk from an open part formed in a panel of the disk, and comprises: a snap fitting part 10; a concave part 20; and a plate spring part 30. The snap fitting part 10 includes a flexible column in which a tip end is contacted to the panel from the inner part of the disk in a state where one part is flexibly contacted to an edge of the open part when it is inserted into the open part, and one part is inserted into the open part. The concave part 20 is arranged at a position where nips the panel from an external part and the inner part of the disk in a state where the one part is inserted into the open part. The plate spring part 30 applies a weight to the panel from the external part of the disk in a state where the one part is inserted into the open part.SELECTED DRAWING: Figure 5

Claims
