A printer having a print command circuit adapted to provide a print command signal, to thereby begin each print cycle is provided. The printer further includes a character ring having print characters circumferentially positioned therearound, each print character being selectively positioned by rotating the character ring from a rest position to a print position in response to the print command signal. The improvement comprises a single position detection circuit for generating character selecti...

A pivotally journalled ink ribbon cassette and an ink ribbon fork are coupled to the carriage of a printing head and arranged so as to be displaceable transversely to the line direction, in a simple manner such that both a multi-color and a single-color mode of operation are obtained. The ink ribbon fork is arranged at its free end so as to be pivotable and longitudinally displaceable on a guide rod journalled in guide arms of the ink ribbon cassette, and in that with respect to the position of ...

In a printer for printing information onto a recording medium, rotation of a platen in a normal direction causes the recording medium to be transported in a normal-feed direction. Rotation of the platen in a reverse direction causes the recording medium to be transported in a reverse-feed direction opposite to the normal-feed direction. Discharge rollers are arranged above the platen for rotation about an axis parallel to a longitudinal axis of the platen at respective peripheral speeds higher t...

The disclosure is directed to a printer which is so arranged that a preliminary paper feeding is effected in the case of normal printing, and upon alteration of printing conditions, the preliminary paper feeding is automatically released, while, after alteration of the printing conditions, the preliminary paper feeding is again effected, and thus, a printer efficient in use has been presented, with an improved through-put in operation.

A printer for printing on a print medium. A type carrier is in the form of an endless belt having a plurality of type elements on a side face. A hammer mechanism urges the type elements in the print medium into contact. The hammer mechanism extends substantially parallel to a portion of the type carrier and includes a hammer member for each printable position of the printer. A print drum mechanism selectively drives the hammer mechanism. The print drum mechanism includes the print drum with a pl...

The present invention provides an improved printer and recording device having an improved design for providing efficient operation and improved print and recording speed to one or more storage devices. In one aspect, the present invention meets the above needs by providing a printer having printing means adapted to operate independently from a transportation mechanism of a storage device. In another aspect, the present invention provides a printer having one or more removable cartridges for the...

A printer with an elongated media output port is disclosed. The printer may be used for a digital tachograph of a motor vehicle. The printer includes at least one bearing surface which limits the media output in the transverse direction and along which the printing medium slides during output. The boundary conditions for the operation of a small-format printer in a digital tachograph of a motor vehicle makes it necessary that the media output port has to be sealed off against the ingress of harm...

A printer has a motor and an encoder. The encoder opposes a scale having marks or slits at predetermined intervals. Staggered detectors detect positions of the marks or slits, and output detection signals. Signal generators output signals with respective frequencies based on the various detectors. A controller detects the rotational position and speed of the motor the signals output from the signal generators, and controls the rotational speed of the motor by PID control on the basis of the posi...

A printer that can reduce a manufacturing cost is obtained. The printer according to the invention includes a casing as a base member, a movable member and a spring. The movable member is movable with respect to the casing. The spring is located between the casing and the movable member. The casing is provided at a position opposed to the lower end of the spring with a projected portion (circular convex portion) arranged to pinch the lower end of the spring. The position of the spring with respe...

A multiplicity of print hammers are supported on one or two planar arrays of leaf springs, the array being parallel to a belt carrying a row of typefaces defining respective character positions, so as to be jointly shiftable parallel to that row between different positions of alignment of each hammer with any one of a set of two or three character positions assigned to it. The hammers are actuated by respective electromagnets whose armatures are normally spaced from the hammers and have faces sp...
