摘要： A printer for selecting automatically types of numerals and/or characters in response to input signals and for printing the selected types of numerals and characters on a printing paper, in which a plurality of type wheels are arranged rotatably on a shaft at regular intervals. Each of the type wheels has an even number of permanent magnets radially arranged from the center of the type wheel at regular intervals in the alternating arrangement of magnetic polarities of the permanent magnets. Type characters are fixed along the periphery of each type wheel at respective projections each arranged between adjacent two of the permanent magnets. One of the types is selected by rotating each type wheel in the clockwise or counterclockwise direction by driving alternately a pair of electromagnets arranged oppositely to one of the types and the pole of one of the permanent magnets respectively until the selected type opposes a print hammer.

摘要： The invention relates to a mechanism for printing values entered in a keyboard or transmitted from a computer. Normally, values entered in a keyboard are entered in the decimal system of notation and values received from a computer or other external source are transmitted in a binary code. With this thought in mind, this invention provides a mechanism for receiving information from either an internal keyboard in decimal values or from an external source in binary coded values, entering said values serially into a storage and printing out said values in parallel.

摘要： A recording system for a business machine of the type having a plurality of character wheels, each having a set of circumferentially spaced characters thereon and being rotatable to a preselected position to display the character entered into the machine. The recording system comprises first and second signal-generating means which are adapted to produce respective sequential first and second signals as each character passes a preselected point during a rotation of a character wheel. Signal means is provided which is responsive to the sequential occurrence of said first and second signals for producing an output signal which is indicative of the character entered into the machine.

摘要： In a printer which selects a character by moving a type wheel by a stepping motor, phases other than a stable phase of windings of the stepping motor are shorted when a rotor of the stepping motor comes to a vicinity of a stable point of a target phase, and an exciting time of the stable phase is gradually extended. The primary drive signal is turned off during energization of a retaining signal and during hammer energization.

摘要： An encoder for a wheel or other devices with relative movement comprises in the use of a printwheel, a linear Hall-effect sensor and magnet mounted in a non-ferrous metal shaft with a flux conducting spiral ring molded in the printwheel and encircling the shaft. The angular position of the printwheel is absolutely determined by the magnitude of the signal relative to the transition point of the spiral. The values are converted to digital information and stored in non-volatile memory for comparison to the values measured as the wheel is positioned during operation of the wheel. In another embodiment, a second Hall-effect sensor is placed on the shaft opposite the first sensor to provide an enhanced signal.

摘要： Independent control by a single motor of two members mounted on a shaft, e.g. print wheels in a printing machine such as a postal franking machine, is enabled by having the first member either fixed in rotation to the shaft or connected to the shaft by a one-way clutch, and having the second member connected to the shaft by a one-way clutch, the arrangement being such that rotation of the shaft in one direction causes movement of the first member only (by direct drive or by the action of the associated clutch) and rotation of the shaft in the other direction causes movement of the second member only, by the action of the associated clutch.
