Elecom also introduced the TK-FBS039E, a wireless keyboard that can be folded along a hinge, making it easier to carry. When opened up, the keyboard measures 260 x 91 x 11 mm (WxDxH), but when folded, it measures 133 x 91 x 23 mm, roughly as big as a portable HDD. The keyboard is both wireless and wired. When wireless, it uses Bluetooth, and Bluetooth HID interface to work with iOS, Android devices, and PCs; when wired, it uses USB with common USB HID driver. When wired, it also charges its battery. The keyboard features a simple 66-key QWERTY English+Japanese layout, with sufficient key travel to provide tactile feedback comparable to notebook keyboards. It is available in black (TK-FBS039EBK) and white (TK-FBS039EWH) color options. Slated for early~mid-April, the TK-FBS039E from Elecom is priced at 7,350 JPY (US $89).
