  • Bed apparatus
    Patent number: 10695244
    Abstract: A bed apparatus including, at least, two drivers or a first driver and a second driver, the first driver being in linkage with the second driver, comprises: a calculating means for calculating a calculated bed state value, based on the first driver and the second driver; an error detecting means for detecting error between the calculated bed state value and a designated bed state value designated by the user; and, an error correcting means for correcting the detected error when an error is detected by the error detecting means. As a result, it is possible to provide a bed apparatus that can coincide the designated state of the bed apparatus with the actual state of the bed apparatus by appropriately correcting the error between the drivers.
