Credit Facilities [Abstract]
Credit Facilities	3. Credit Facilities The Company had no debt outstanding at June 30, 2012 and June 30, 2011. The Company has a $6.0 million secured credit agreement with Comerica Bank (“Credit Agreement”), which expires on November 1, 2013. Proceeds under the Credit Agreement may be used for working capital and capital expenditures. Security under the Credit Agreement is substantially all non-real estate assets of the Company held in the United States. Borrowings are designated as a Libor-based Advance or as a Prime-based Advance if the Libor-based Advance is not available. Interest on Libor-based Advances is calculated at 2.35% above the Libor Rate offered at the time for the period chosen, and is payable on the last day of the applicable period. Quarterly, the Company pays a commitment fee of 0.15% per annum on the average daily unused portion of the revolving credit commitment. The Credit Agreement prohibits the Company from paying dividends unless previously approved by the bank. The Credit Agreement requires the Company to maintain a minimum Tangible Net Worth, as defined in the Credit Agreement. The Credit Agreement also requires the Company to have no advances outstanding for 30 days (which need not be consecutive) during each calendar year. At June 30, 2012, the Credit Agreement required a Tangible Net Worth of not less than $34.2 million. The Company was in compliance with this financial covenant. On August 30, 2012, the Company entered into a Second Amendment to the Credit Agreement, which allowed for the sale of CBU assets and amended the Base Tangible Net Worth definition to require a Tangible Net Worth of not less than $33.2 million. The Company’s bank agreed to amend the Amended and Restated Credit Agreement to allow the Company to declare and pay dividends of up to $2.8 million in fiscal 2013 and up to $1.8 million for each fiscal year thereafter provided the Company maintains a minimum Tangible Net Worth as defined in the Credit Agreement. At June 30, 2012, the Company's German subsidiary (GmbH) had an unsecured credit facility totaling 350,000 euros (equivalent to approximately $440,000). The facility allows 100,000 euros to be used to finance working capital needs and equipment purchases or capital leases. The facility allows up to 350,000 euros to be used for providing bank guarantees. The first 100,000 euros of borrowings bear interest at 8.5% and 2.0% is charged on borrowings over 100,000 euros. The German credit facility is cancelable at any time by either GmbH or the bank and any amounts then outstanding would become immediately due and payable. At June 30, 2012, GmbH had no borrowings outstanding.
