ータ。[Claims for Utility Model Registration] The body has a fixed anvil at one end and a movable anvil at the other end, and the measured value detected from the amount of displacement of the movable anvil is digitally displayed on a digital display. In the digital display type inner micrometer, the digital display is provided in the middle part of the main body, an operation switch is installed near the digital display, and a movable anvil is mounted on the main body on the movable anvil side with the digital display sandwiched therebetween. A driving mechanism to be moved and an encoder for detecting the amount of displacement of the movable anvil are installed respectively, and a power source is installed in the main body on the fixed anvil side, and the driving mechanism is connected to a motor driven by the operation switch, and an encoder for detecting the amount of displacement of the movable anvil. a friction sleeve that is fitted onto the rotating shaft of the motor via a friction spring and has a keyway extending in the axial direction; one end has a pin that slidably engages with the keyway of the friction sleeve; the other end has a pin that is slidably engaged with the keyway of the friction sleeve; The encoder has a movable anvil and a spindle screwed onto the main body and are arranged on the same axis, and the encoder is rotatable in synchronization with the spindle of the main body and is resistant to axial displacement of the spindle. What is claimed is: 1. A digital display type inner micrometer, characterized in that it is provided in a non-displaceable manner and is connected to the digital display via a reference setting means for forcibly setting the displayed value to zero regardless of the position of the movable anvil.
