Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements GAAP utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to observable quoted prices (unadjusted) in active markets for identical assets and liabilities (Level 1 measurement), then priority to quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market (Level 2 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). As of October 29, 2016 and January 30, 2016 the Company had $450,000 in Level 2 investments in the form of bank certificates of deposit. The Company's investments in certificates of deposits were measured using inputs based upon quoted prices for similar instruments in active markets and, therefore, were classified as Level 2 investments. As of October 29, 2016 and January 30, 2016 the Company also had long-term variable rate Credit Facilities, classified as Level 2, with carrying values of $86,115,000 and $72,414,000, respectively. As of October 29, 2016 and January 30, 2016, respectively, $2,993,000 and $2,143,000 was classified as current. The fair value of the variable rate Credit Facilities approximates and is based on its carrying value. The Company has no Level 3 investments that use significant unobservable inputs.
