Ricoh Co., the nation's second-biggest office equipment maker, said Tuesday it expects operating profit and sales to rise in the next three years.

Operating profit, or sales minus the cost of goods sold and administrative expenses, will probably climb 33 percent to ¥250 billion for the 12 months ending on March 31, 2011, Tokyo-based Ricoh said in a statement Tuesday outlining its three-year business plan. Sales are projected to rise 11 percent to ¥2.5 trillion over the same period, Ricoh said, without providing a net income figure.

The company on Jan. 30 forecast operating profit will rise 7.8 percent to ¥188 billion this business year, while sales may climb 8.8 percent to ¥2.25 trillion.

Ricoh said it was assuming a yen exchange rate of 105 to the dollar and 155 to the euro for the targets.
