摘要： An improved label stamper which is capable of stamping prices on labels attached on a tape so as to attach the stamped labels on commodities is disclosed. A tape loading mechanism of the label stamper is constituted such that a loading case goes in and out of the machine by functions of a pair of folding and extending legs, so that the label tape can be loaded in a convenient manner. A guide is constituted such that a front plate and a rear plate are fastened across a narrow gap, and this gap forms a guide channel. In a holding mechanism, a push plate is disposed facing toward a base plate, and the push plate interlocks a movable lever to the loading case. Thus, if the tape is inserted into the guide channel, the tape is automatically press-held to the base plate. In a stamping mechanism, a selecting hole of a selecting wheel for driving a stamping belt is provided with a recess and a triangular protuberance. Thus two selecting wheels will never be engaged together, and fingers of a selecting bar are accurately coupled to the selected wheel. In a carrying mechanism, carrying rollers are provided in the form of a cartridge, and this cartridge is replaceably accommodated within a cartridge compartment. This improves the compactness and the performance of the label stamper, and the cartridge can be conveniently replaced.

摘要： A method of preparing a nonmagnetic one-component pulverized color electrophotographic developer, includes: preparing a master batch by melt-kneading at least two binder resins and wax; and melt-kneading a mixture of the master batch, a colorant, and a charge control agent. According to the method, paper jams can be decreased and a toner having wide fixing margin can be obtained by preventing wax from being dispersed mainly in a resin having a similar melting property as wax during melt-kneading to prepare a toner. An electrophotographic developer prepared using the method can prevent image contamination and developing member contamination. Also, the electrophotographic developer can guarantee wide fixing margin of the toner, and thus can be efficiently used in an electrophotographic image forming apparatus.
