	RIKEN RI Beam Factory (RIBF) was constructed as the first of the next-generation radioactive-beam facilities aiming at investigating vast unknown fields of unstable nuclei. In order to obtain the world-most intense heavy-ion beams, we have employed, taking into account cost effectiveness, a multistage acceleration scheme including 4 ring cyclotrons. We have already obtained 1 pμA, 0.42 pμA, and 24 pnA beams for 18O, 48Ca and 124Xe ions, respectively. The present performance has been obtained by using very conventional beam instruments such as Faraday cups, wire scanners and so on. Beam instruments used in RIBF are briefly summarized putting emphasis on beam tuning methods using them. In addition, limitations of these conventional devices and possible upgrade of beam instruments are discussed for further intensity upgrades and more stable operations of RIBF.
