計測器。[Claims for Utility Model Registration] 1. A first light-emitting element that can irradiate light onto a rotating body to be measured, and a light-receiving element that can receive the irradiated light from the first light-emitting element as reflected light. The main body has an optical detection system with a rotation detection shaft that is in contact with the rotation detection shaft so as to be able to move toward and away from the rotation detection shaft; a light transmission rotary plate that is rotatable according to the rotation speed of the rotation detection shaft and has a light-transmitting part and a non-light-transmitting part; A second light emitting element capable of irradiating light to the light receiving part of the main body located from one side of the transmission rotary plate to the other side is disposed, and the second light emitting element and the first light emitting element The element is a switching circuit of the lighting circuit so that the second light emitting element can be lit when the adapter is attached to the main body, and the first light emitting element can be lit when the adapter is removed from the main body. A rotation speed measuring device characterized by the following: 2. The main body includes an optical detection system comprising a light emitting element capable of irradiating light onto the rotating body to be measured, and a first light receiving element and a second light receiving element capable of receiving the irradiated light from the light emitting element as reflected light. The adapter, which is attached to the body part and is removably combined with the main body part in order to enable switching between a non-contact method and a contact method, is in contact with the center of rotation of the rotating body to be measured so as to be able to come into contact with and separate from the adapter. and a light reflecting rotary plate which is rotatable according to the rotational speed of the rotation detection shaft and has a reflective part and a non-reflective part divided into two, and the first light receiving The element and the second light receiving element are the second light receiving element when the adapter is attached to the main body.
A switching means for the light receiving circuit is provided so that when the adapter is removed from the main body of the light receiving element, the first light receiving element can receive the irradiated light from the light emitting element as reflected light. A rotation speed measuring instrument characterized by:
