Earnings Per Share, Basic and Diluted [Abstract]  
Income Per Common and Common Stock Equivalent Share
Basic (loss) per share is computed based on the weighted-average number of common shares outstanding.  The weighted-average number of common shares outstanding was 7,382,706 for the years ended June 30, 2018 and 2017.  When dilutive, stock options are included in (loss) per share as share equivalents using the treasury stock method.  For the years ended June 30, 2018 and 2017 there were no common stock equivalents related to stock option grants that were included in the computation of the weighted-average number of shares outstanding for diluted (loss) per share.  Shares issuable upon the exercise of outstanding options of 2,405,000 and 2,180,000 were excluded from the diluted weighted average common shares outstanding for the years ended June 30, 2018 and 2017, respectively, as they would be anti-dilutive.
