Concentrations of Credit Risk	12 Months Ended
	Jun. 30, 2012
Fair Value Disclosures [Abstract]
Concentrations of Credit Risk	9.  Concentrations of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, accounts and trade receivables and leases and mortgages receivable.  The Company maintains its cash and cash equivalents, including a money market account, at a large bank. At times, the bank deposits may exceed Federal Deposit Insurance Corporation (FDIC) limits.  Concentrations of credit risk with respect to trade receivables are limited due to a large customer base.  Also, based on the Company’s credit evaluation, trade receivables are often collateralized by the equipment sold.
