Abstract: A security system for electronic circuits (e.g. electronic circuits contained within a secure POS terminal) is provided that is both more tamper resistant, and tamper responsive and less expensive than the prior art epoxy potting. This is achieved by inserting an electrical connector between a first and a second circuit board contained within a case of the POS terminal. The first and the second circuit boards are any type of circuit board known in the art, including both not limited to, rigid circuit boards, flexible circuit boards, printed circuit boards, etc. If the case is opened the connector no longer provides an electrical connection between the first and the second circuit boards, triggering a tamper detection circuit. In some embodiments of the invention, a flexible conductive film is wrapped around the circuit boards and the connector.

Abstract: A paper conveyance system for individually transporting cut sheets having various thicknesses and rigidity through a printing device includes a main roller for driving the cut sheets, a nip pair located downstream of the main roller, and a top paper guide movable to accommodate the cut sheets having variable thicknesses. The cut sheets are transported between the top paper guide and the main roller and the system includes a device or limiting mechanism for preventing the top paper guide from rotating greater than a predetermined amount in the event that thick or stiff sheet material is conveyed through the printing device. With such an arrangement, both thin sheet and thick sheet material can be accurately directed to a nip roller pair located at an outlet of the printing device. A holder for an upper one of the roller nip pair also includes a tapered guide portion for guiding the leading edge and the longitudinal edges of the sheet material as the sheet material passes through the nip roller pair.
