Abstract: A character wheel, particularly for a numbering machine, comprises a character wheel disc having a plurality of printing portion mounting surfaces formed at an interval from each other in a circumferential direction on an outer peripheral surface of the character wheel disc and an engaging groove formed to at least one of portions between the respective printing portion mounting surfaces and a flexible character wheel band mounted to the outer peripheral surface of the character wheel disc. The character wheel band is formed with engaging projections formed at both longitudinal ends thereof and the engaging projections are engaged with the engaging groove formed to the character wheel disc so that the flexible character wheel band is mounted to the character wheel disc therearound.

Abstract: An ink roller device which permits easy and smooth removal and installation of an ink roller without soiling hands and which also ensures a prolonged service life of the ink roller, and a numbering machine which is equipped with the ink roller device. The numbering machine is equipped with a numbering main body comprised of a frame, a character wheel unit which is incorporated in the main body so that it is allowed to move up and down between a printing position and a home position thereof, an operating means equipped with an operating knob which enables the character wheel unit to be depressed against the spring force of a resetting spring, a swinging arm mechanism which is provided on the numbering main body and which can be swung as the operating knob is depressed, and a cassette-type ink roller device which is detachably held at the bottom of the swinging arm mechanism.

Abstract: An apparatus for guiding a carbon ribbon from a supply reel to a take-up reel includes an adjusting member which is used for securing a guide rod around which the carbon ribbon passes to a fixed plate. A bolt passes through an off-center hole in the adjusting member and upon tightening of the bolt, one end of the rod is secured to the fixed plate. The other end of the rod is pivotably secured in a base plate. Therefore, by turning the adjustment member, the location of the off-center hole is changed and the inclination of the rod is adjusted. By suitable setting of the adjustment member, the orientation of the rod is adjusted so that a uniform tension is applied across the ribbon tape to thereby prevent wrinkling or misalignment thereof.

Abstract: A desk-top and/or hand held thermal printer comprises a main unit having a guide path therein for a moving continuous label strip which includes a backing sheet and discrete labels detachably attached to the backing sheet. The printer has a flat bottom surface for resting on a flat surface; a retaining means for supporting a roll of backing sheet and labels and guiding the labels through a thermal printing device where a bar code or the like is thermally printed on the thermosensitive labels; a label peeling means for peeling the labels from the backing sheet; a label affixing means for affixing the peeled-off labels on objects; a data input means for example a keyboard or a computer input terminal; a data display means; and a controller for controlling the entire printer.
