Abstract: A simplified and compact typing machine to be incorporated in an electronic calculator has a type wheel for presenting different numerals upon rotation. The type wheel is moved along a line of digits, i.e., laterally and in the generally horizontal direction, for typing successive numerals and the typing is performed when a hammer head is swung, or the type wheel is rotated, by the movement in one direction of an acting rod of an electromagnetic relay. The same relay acting rod also laterally moves the type wheel in the direction of the line of digits, on its return motion, by a distance corresponding to the space of one digit.

Abstract: A printer apparatus including a timer, for setting a period T1 when the print head moves forward toward a platen, and a period T2, which is longer than period T1, when the print head moves away from the platen. In response to an interrupt signal from the timer, a CPU supplies a signal, for changing over the exciting phase of the stepping motor, to a motor driving circuit. As a result, the motor driving circuit operates to speed up the rotation of the stepping motor when the print head moves forward, providing a low level of torque with which to move the print head toward the platen. On the other hand, the motor driving circuit operates to slow down the rotation of the stepping motor when the print head moves away from the platen, providing a high level of torque with which to move the print head away from the platen.

Abstract: A printing apparatus is provided which utilizes rolling pressure contact for printing, and includes a plurality of sets of serially arranged character elements mounted for movement on the external surface of a printing drum. Movement of the sets to place a desired character into printing position is accomplished by controlling the speed of a motor driving a pulley connected by cable to a given character set, relative to the speed of a motor driving the printing drum in rotational movement.

Abstract: A modular high speed printing system for printing alphabetic and numerical information upon individual items or documents fed individually or in series through the modules. A feeder module performs accounting functions as to the number of documents processed, provides multiple or single mode document feeding and is adjustable to accommodate different size documents. The system also includes one or more printing modules for printing machine readable repetitive data, machine readable consecutive data, repetitive alphanumeric information and consecutive numeric information. A document receiver module adjustable to different size forms is also provided. The printing modules employ common document drive systems including an adjustable document end stop to permit horizontal placement of the information on the document. Vertical positioning of the information on the document is accomplished by means of adjusting the print mechanisms. The individual modules can be selected for operation in active or bypass modes and single cycle or flow feeding modes.
