Abstract: An apparatus provided with a carriage is guided and supported by at least two guide members, a guide shaft and a guide rail, arranged to be parallel to each other to enable the carriage to reciprocate. The guide members are arranged apart from each other substantially in the vertical direction, and the horizontal distance L1 between each guide member and the gravitational center of the carriage is arranged to be larger than the vertical interval L2 between the contact portions of the carriage and each guide member. With the structure thus arranged, it is possible to maximize the reduction of the swinging or vibration of a carriage so that the apparatus provided with the carriage can effect reciprocal scanning exactly and stably, thus realizing a small and high-performance apparatus that records images in high precision or reads highly precise images.

Abstract: Machine-readable light-colored or invisible, but luminescent, postage-evidencing symbology and dark, readable other postage information are printed, preferably in a single print operation, to provide large amounts of information without diminishing read rates. The resulting combination image can be printed independent of substrate material to enable the provision of a high information density without obscuring any one component. The postage-evidencing symbology is printed in large-format and can include redundant information within an IBI image or between an IBI and visible dark image for a variety of practical purposes. In a preferred form, the images are printed using conventional ink jet printers using water-based inks. In one embodiment of this type, the images are printed with a conventional two-cartridge color ink jet printer by printing postage-evidencing symbology with a single-color ink and printing the visible dark image as a composite dark color from a standard multi-color cartridge.
