摘要： A printer having a printing mechanism for placing printed matter on a substrate, the printing mechanism including character printing elements and an electrically driven hammer unit which is connected to receive an actuating current and is operative for causing the printing elements to print characters on the substrate by impacting against the elements with an impact force dependent on the magnitude of the actuating current, the printer being further provided with: a substrate thickness monitoring device mounted in the printer for monitoring the thickness of a substrate disposed to be printed upon by the mechanism and for producing an electrical output signal indicative of the substrate thickness; and an actuating current control circuit connected to receive the output signal from the monitoring device and to control the actuating current in a manner to reduce the impact force when the substrate thickness is less than a selected value.

摘要： In an impact printer including a print wheel having a plurality of selectable character type bearing elements for respectively printing a plurality of characters, said print wheel being rotatable for selectively positioning selected type elements in successive print positions, impact means impellable against the selected elements to drive said elements against the printing medium and means for impelling the impact means against said selected type element, the present invention provides the improvement comprising the combination of means (20, 24) for sensing the flight time of the impelled impact means until impact by sensing variations in the velocity of said impact means, means (25) for comparing the sensed flight time to a predetermined desired flight and means (27) for selectively varying the amplitude of the current to the impelling means (23) to adjust the sensed flight time to equal the desired flight time.

摘要： A platen assembly for an impact printer comprises the combination of an impact transducer (28) between the backup plate (23) and the type band (11) of a printer and an impact isolator (29) interposed between the transducer and the type band. The transducer comprises a strip of force sensitive material. The strip extends over a plurality of print positions. Electrode means in contact with the surfaces of the force sensitive material form discrete impact zones aligned with the print hammers. One of the electrode means is a continuous conductive strip on one side of the force sensitive strip. Plural conductive pads on the other side of the strip form the discrete impact zones. The transducer element can be a foil using PVF2 with etched conductive patterns forming the electrodes.

摘要： The preferred embodiment discloses an entirely new impact-type electronic printer using a rotary printing wheel which enables the ROM to store printing-type position data for dealing with respective printing types borne by the rotary printing wheel, hammer pressure data, and the spacing data respectively matching the designated printing types together with printing-type position data. The main CPU then draws out the printing-type position data, hammer pressure data, and the spacing data in response to the input data to allow the printer to execute the printing operation using the designated printing types in accordance with these data drawn out of the ROM, thus realizing distinctly clean printed characters. The unique system embodied by the present invention makes it possible for the controller to easily read important data from the ROM. In other words, since the control system reflecting the present invention allows the ROM to effectively store the printing-type position data, hammer pressure data, and the specifying data, the control system can, for example, securely read the data merely by executing the reading operations twice.

摘要翻译：优选实施例公开了一种使用旋转印刷轮的全新的冲击式电子打印机，其使得ROM能够分别存储用于处理由旋转印刷轮承载的各种印刷类型的打印型位置数据，锤压数据和间隔数据将指定的打印类型与打印类型的位置数据匹配。然后，主CPU然后根据输入数据抽出打印位置数据，锤击数据和间隔数据，以使打印机能够根据这些数据中的这些数据使用指定的打印类型执行打印操作 ROM，从而实现清晰的打印字符。由本发明实现的独特系统使得控制器可以容易地从ROM读取重要的数据。换句话说，由于反映本发明的控制系统允许ROM有效地存储打印类型位置数据，锤压数据和指定数据，所以控制系统可以例如仅仅通过执行控制系统来安全地读取数据阅读操作两次。

摘要： A variable impact printing mechanism includes a supporting magnetic structure (12) having a plurality of circumferential coils (40-48) mounted thereon and having a central bore (14) in which a magnetic hammer (16) is positioned for linear movement to cooperate with a type member (22) positioned adjacent to one end of the bore (14) in order to effect printing on a record member (24) positioned between the hammer (16) and the type member (22). A controller (100) including a microprocessor and table look-up memory is provided to energize drivers (50-58) for the various coils (40-48) in predetermined sequences to vary the velocity achieved by the hammer (16) at the end of its printing movement in accordance with varying printing requirements.
