MAXI (Monitor of All-sky X-ray Image) is the first astrophyscial palyoad for japanese Experiment Module (JEM) to be designed for all sky X-ray monitoring. MAXI is a slit scanning camers which consists of two kinds of X-ray detectors; one is one-dimensional -oition sensitive proportional counters with total area of approx 5000 cm~2 (here we call GSC) and the other is an X-ray CCD array with toal area approx 200 cm~2 (here we call SSC). The GSC subtends a field of view with an angular dmension of 1 degree times 180 degrees, while the SSC does a field of view with an angular dimension of 1 degree times a little less than 180 degrees. Thus, in the course of one station orbi, MAXI can scan almost all sky with a precison of 1 degree and with X-ary energy range of 0.5-30 keV. MAXI with a total weight of about 500 kg will be attached to JEM exposed facility in 2003.
