An improved printer for selectively imprinting a clear pattern carried by a pattern carrier on an imprint receiver. The printer is provided with a pattern carrier, an imprint receiver for receiving the carried pattern, means for recording the pattern on the imprint receiver, at least one print hammer for striking the imprint on the imprint receiver and means for advancing the print hammer for striking the imprint on the imprint receiver.

A plurality of printing components each are attached to a movable transport means to extend along a line of print with respect to a recording means. A permanent magnet is attached to each of said components and an electromagnet is fixed in spaced relationship to said permanent magnets. The permanent magnets having their polarity varying alternately from component to component. The electromagnet is selectively excited with a given polarity to produce a deflection of one or more permanent magnets ...

A small-sized and light weight printer which can suitably be incorporated in a desk-top calculator or the like. The printer has a simplified mechanisms for driving of a printing head, a paper feed and a printing control, and can operate stably with a reduced power consumption.

A printer of the type in which a receipt paper and a journal paper are arranged in parallel to each other, after the receipt paper and journal paper have been transferred in a horizontal direction, the receipt paper is passed through a vertically moving cutter device and issues from the printer in a horizontal direction whereas the journal paper is turned upwardly and wound about a take-up roll; printing drums for the receipt paper and the journal paper are disposed below a horizontal paper tran...

The printer includes a slide member adapted to be reciprocally moved by a drive source. The printer comprises a paper cutting member reciprocally movable for cutting the printed paper, a connecting member connected to the paper cutting member and arranged so as to be engaged with and disengaged from the slide member, and an electromagnetic device adapted to be actuated by a paper cutting signal for controlling the engagement and disengagement of the connecting member with and from the slide memb...

A printer has a stationary electromagnet device, a hammer having a permanent magnet therein, and a resilient member coupled to the hammer. The permanent magnet may be moved upon electrical energization of the electromagnet device to cause the hammer to impact against a character by mechanical energy accumulated in the resilient member.

A printer especially suitable for printing letters and symbols on a recording media having portions of different thickness such as a bank deposit pass book foldable along a folding line. A movable platen is comprised of left and right units and a central unit which are moved toward and away from the recording medium by rotary cams and spring means so that the upper surfaces of the left, right and central units of the platen are always maintained in the same plane parallel with the running path o...

The printer is provided for alternative use with long webs or individual, precut forms; it includes two friction roll drives adjacent to the print head and platen, and a sprocket drive upstream, being permanently engaged with a perforated web. The drives operate in synchronism but do not participate in all operations. Printing on the web is carried out after advancing the web by one form length and retracting it during stop and go printing. Switches control access to a bypass, the insert for a s...

An improved printer comprising a plurality of character rings provided with a plurality of characters on the respective peripheries thereof and corresponding pluralities of ratchet wheels and pawls. Each ratchet wheel is radially mounted on a character ring and a corresponding pawl is oscillatably mounted for engaging its corresponding ratchet at a preselected interval for stopping its associated character ring when a selected character is located at a predetermined position. Guides are provided...
