Abstract: A price indicator mounting unit which can install a price indicator at any place of a showcase (set of display shelves) and at any kind of display board (display shelf) easily but can not be removed easily by customers. Also, the price indicator mounting unit is inexpensive and capable of getting optional setting angle freely. The price indicator mounting unit comprises one or a plurality of display board mounting members and indicator mounting members, wherein the display board mounting member constituted of a bracket, a stopper plate and a screw, and as the screw is tightened, the both ends of the bracket are opened outward by the stopper plate put between the both ends to engage with a display board. In addition, by replacing the display board mounting member with another one, the connection with a flat rail becomes possible.

Abstract: A multi-function printer can print on two different types of record media, one of which types of record media is continuous, such as may be used for printing receipts, and is stored within the printer, and a second of which types of record media is discontinuous, may be of varying thickness, and is introduced from the exterior of the printer. A reversible motor and associated transmission mechanism provide means for driving the two types of record media, and a pivotally mounted solenoid-driven platen arm provides for selective engagement of driving means in the printer and for altering the gap between the printhead and the platen of the printer in accordance with the thickness of the record media to be printed upon.

Abstract: In a slip printer, the slip is inserted or placed on the slip table at 90.degree. to normal orientation to accommodate slips which are wider than the print station. Character data and space data are input into memory and printing is done by shifting out character data along with space data on either side of the character in dot by dot manner. A pattern processing section is capable of changing the arrangement of the dot pattern read out from memory, a space data generating section is adapted to output space data signals before and after output of pattern data from the processing section, and a print data buffer stores the process data and the space data for one line dot row prior to printing.

Abstract: A dot matrix printer utilizes an inking roller for supplying ink to the surface of the printer platen and has guide means adjacent the platen to separate the print paper from the platen. The guide means includes an elongated slot or window for access to the platen by the print wires. The print wire support means is spring loaded in a direction toward the platen and utilizes a solenoid to move the support means away from the platen. A pair of rollers is engageable with the paper and positioned between the platen and the print element carriage to form a predetermined space between the paper and the end of the print wire when the carriage is moved toward the platen.

Abstract: A ribbon cassette with re-inking mechanism includes a removable ink supply tank having a low density ink element and a high density ink element, and an ink transfer roller engaging the high density ink element and having an uneven surface on the periphery thereof for carrying ink in controlled manner from the high density ink element to the ribbon.
