Abstract: The calculator is small enough and well protected enough to be carried in the pocket. In addition to a keyboard 28, circuit board 29, batteries 18 and an LCD data display 91, there is a printer comprising a platen 36 which draws paper from a roll in a compartment 101. A thermal printing head 33 is reciprocated along the writing line by a pin 44 engaging in an eccentric cam groove in a disc 46 rotated by a crown wheel 53 and a pinion 54 on the shaft of a motor. Another cam-follower pin 64 reciprocates a slide 66 which advances the platen incrementally after each traverse of the head 33. A slidable cover 14 is shown open, exposing the printing mechanism and operating a switch which enables the printer. Results appear on the LCD display and are printed. When the cover is slid closed it protects the printing mechanism and disables it via the switch. The calculator can nevertheless be used without the printer, results being displayed only on the LCD display 91. The paper roll is carried in a removable container 132 to which access is obtained by depressing a detent tongue and sliding the cover still further open. Cooperating parts of the container and the calculator frame guide the leading strip of the paper between the platen and print head. When the cover is closed it bends a tongue of the container to nip the paper and immobilize it.

Abstract: There is disclosed a numbering machine designed so that code numbers as well as check digits each consisting of a single-place digit are printed by means of a mechanical mechanism. The check digits are printed by a check digit type wheel having an arrangement of circulating digits which are calculated in correspondance with code numbers in accordance with a modulus 10 or 11 check with predetermined weights. When there is a carry from one code number digit place to the next higher digit place, it is necessary to print the digit skipped a predetermined number of the digits in the circulating digit arrangement, and as a result a drive control mechanism is provided so that when a change from one code number to the next higher code number necessitates a skipping operation, the change is detected and the check digit type wheel is rotated idly through a predetermined angle.

Abstract: The present invention is directed to a printer and display system wherein the images from an optical character generator are directed along two separate optical paths. A planar light-to-heat transducer element is positioned in one of the optical paths to intercept the generated character images for thermal printing a permanent reproduction of the intercepted characters. A visual display is positioned in the other optical path to intercept the generated character images for forming viewable images of the generated character images.

Abstract: A compact flying printer has a continuously rotating print drum and ratchet wheel, a trigger lever positionable to be struck by a tooth of said ratchet wheel and a hammer lever driven by said trigger lever and provided with a print hammer at its end. Both print paper and inked ribbon are selectively advanced by a transmitting lever. The transmitting lever is mounted for reciprocal displacement and is operatively coupled to a continuously rotating member for selective displacement in response to the rotation of the rotating member. The print paper is guided by an upper and a lower paper guide, each of which are provided with projections on the inner surface thereof extending in the direction of travel of the print paper and projecting toward the other paper guide. The projections on the two guides are out of overlapping relation with each other. The gap between the outer surfaces of the projections of the respective paper guides is substantially equal to the thickness of the print paper.

Abstract: A printing mechanism comprises a rotary print drum having around the periphery thereof a series of circumferentially spaced-apart rows of print type, a drive system for electromagnetically rotating the print drum in an intermittent manner to successively position the rows of type in a print position, and a positioning device for automatically positioning the print drum in the same start position each time the printing mechanism is turned ON. The drive system comprises a ratchet wheel connected to the print drum, a pawl engageable with the ratchet wheel, an electromagnet responsive to pulse signals for electromagnetically reciprocating the pawl to effect intermittent rotation of the print drum, and an electric control circuit for successively applying pulse signals to the electromagnet. The positioning device includes a cam connected to the ratchet wheel for intermittent rotation therewith, a lock lever pivotable into camming engagement with the cam, and an electromagnet responsive to a position signal developed by the electric control circuit for pivoting the lock lever into engagement with the cam. The intermittent rotational movement of the ratchet wheel effects a corresponding movement of the cam until the print drum is moved into the start position afterwhich the lock lever coacts with the cam to prevent further movement of the ratchet wheel even though pulse signals may continue to be applied to the drive system electromagnet.

Abstract: An electromechanical apparatus for imprinting a six digit number on a charge receipt. Six geared print wheels are rotatably mounted on a common shaft and each wheel associates with an electromagnet activated camming arm. For each impulse of an electromagnet, the associated print wheel is rotated about its axis for one-tenth of a turn. A zero-lock mechanism is provided so that upon the activation of the print wheel electromagnets for a predetermined number of times without the activation of a zerolock electromagnet, each print wheel is positively reset to zero. The print wheels are restrained against movement in the absence of an activating pulse to the print wheel electromagnets.
