Canon will start selling a new device [JP] that triples as a computer mouse, a calculator, and a numeric key pad starting late July. The LT-100TKM will be available in black or white for $32.

When folded, the battery-powered device can be used as an optical mouse (1,000 dpi). When you open it, the LT-100KTM turns into a 10-key numeric keypad. It can also be used as a stand-alone pocket calculator.

Canon says they expect to sell 15,000 units of the Japan-only device in one year.
