Patent number: 5712629Abstract: A device (12) for interfacing an external peripheral unit (18) to a store controller (16) and store terminal (14) of a point of sale (POS) system has been provided. The interface device includes an MPU (50) for passively monitoring the data coming from the store terminal without causing any interruption to the POS system. When a specific key sequence indicative of a request for use of the peripheral unit has been detected, the device interrupts the flow of data between the store controller and store terminal and enables the MPU to now send data to the store controller and store terminal. Additionally, the device provides a plurality of data paths for allowing the MPU to read data from the store terminal, for storing and reading data from the store controller, and for transferring data between the MPU and the peripheral unit.Type: GrantFiled: June 5, 1995Date of Patent: January 27, 1998Assignee: DCNS, Inc.Inventors: Charles D.

Patent number: T998003Abstract: In a printing mechanism, the leading edge of a sheet of paper is fed onto the printing surface of a cylindrical drum and is clamped thereto. A gear is rotatively attached to the drum, and a sensor controlled gear segment clutch, which is mounted for rotation independently of the drum, controls the clamping and rotational movement of a clamp for clamping the trailing edge of the sheet of paper. The sensor senses when the trailing edge of the sheet passes thereby and activates the gear segment clutch which rotates toward the gear attached to the drum and engages it. The rotational movement of the gear segment clutch results in the closing of the trailing edge clamp onto the trailing end of the sheet of paper. The gear attached to the drum rotates the gear segment clutch and it in turn rotates the trailing edge paper clamp which now rotates the drum. Consequently, the above described printing mechanism can clamp both ends of variable length paper onto a cylinder and rotate it for a print operation.Type: GrantFiled: October 1, 1979Date of Patent: September 2, 1980Assignee: International Business Machines CorporationInventor: Donald L.
