Patent number: 6527185Abstract: In a bar-code reading apparatus, an enclosure is provided with various mechanisms, includes a hand-holding portion and a reading portion having a reading window. Projections are provided at two sides of the enclosure, and a cable extends out from one of the projections. The projections engage with supporting-point cut-out portions of supporting portions in a stand, in a stationary condition. The reading window is therefore located lower than the hand-holding portion.Type: GrantFiled: January 29, 2002Date of Patent: March 4, 2003Assignee: Fujitsu LimitedInventors: Hiroaki Katoh, Mitsuharu Ishii, Toshimitsu Kumagai, Yuichirou Takashima
