As a control means, the CPU 51 turns on the connection with the recording unit 56 to start recording when the time data input from the clock circuit 60 reaches the scheduled start time, and When the time data input from the clock circuit 60 reaches the scheduled end time, the connection with the recording unit 56 is turned off and the recording is ended. Further, the CPU 51, as a detection means, detects whether or not there is a predetermined input error before storing the input schedule data in the storage unit 56, and when an error is detected, the error display is displayed on the display unit 53. To do. Further, the CPU 51 uses A / A as a recording control unit.
The measurement data (digital signal) input from the D converter 59 is recorded in the storage medium 57 in association with the identification number (identification information) input by the input unit 52.

The input section 52 is composed of an input key for inputting a date and time for setting a schedule, an identification number, etc., a setting key for setting various functions, etc. Output to. The display unit 53 is configured by an LCD (Liquid Crystal Display) or the like, and displays the operating state, the current time, and the like input from the CPU 51.

The present invention is not limited to the vibration measurement data storage device 1 of the above embodiment, but may be modified in various ways. For example, although the vibration measurement data storage device having the configuration in which the vibration detector and the storage means are integrated has been described, the vibration measurement data storage device may be separately configured and connected via a cable or the like. Further, the vibration detector is not limited to the overdamped acceleration sensor, and may be any one as long as it can detect vibration. The identification information may be figure information in addition to numbers and characters.
