Amendment July 20, 2002 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] (1) A front panel portion of a casing that incorporates at least a microcomputer, a battery, and a display device connected to the output terminal of the microcomputer receives the output of the display device and transmits a vibration frequency. A main body equipped with a digital display section, a vibration detector detachably attached to a part of the vibrating body to be measured, and a conductive conductor that derives the detection force of the vibration detector and is connected to the connector section of the main body. The vibration detector, which is attached to a part of the vibrating body to be measured, uses the detected force immediately after the vibrating body to be measured is started or stopped immediately after the vibrating body to be measured is used as the calculation result of the microcomputer. A portable resonance vibration frequency meter, characterized in that the resonance vibration frequency is displayed as a digital value on the display section. (2) The main body is provided with a first switch for switching between the first type of vibrator and the second type of vibrator, and when the first switch is switched to the first type position, the display section The resonant vibration frequency is v. p.
m. Claim (1) wherein the resonant vibration frequency is digitally displayed in Hz (times/min) on the display unit when the second type position is selected. ) portable resonant vibration frequency instrument. (3) The casing further includes a built-in amplifier and an A/D converter that receives the output of the amplifier, and the main body has a model switching device for switching between a first type vibrator and a second type vibrator. A switch is provided, and when the switch is switched to the first type position, the amplifier has a high gain, and when the switch is switched to the second type position, the amplifier has a high gain. The portable resonant vibration frequency meter according to claim 1 or 2, wherein the portable resonant vibration frequency meter has a low gain.
