Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	10.        Income Taxes We recorded income tax expense of $2.3 million for the fiscal 2018 first quarter compared to $1.4 million for the comparable prior year period.  The effective tax rates for the fiscal 2018 and 2017 first quarters were 33.0% and 35.8%, respectively.  Our effective tax rate was lower in the fiscal 2018 first quarter as a result of a state tax credit received during the quarter. The net unrecognized tax benefits as of April 30, 2017 and January 29, 2017, which, if recognized, would affect our effective tax rate are $203,000 and $201,000, respectively. Tax years ending February 2, 2014 through January 29, 2017 remain subject to examination by federal and state taxing authorities.
