Abstract: An automatic sales slip register for credit card. This register imprints embossed characters of a submitted credit card on a sales slip when issuing the sales slip, thus to prevent issue of sales slip when no credit card is submitted. The main body of the register includes a card insert slit, a slant support block supporting a lower end of the credit card inserted in the card insert slit, a stopper preventing the card from sliding off the support block and guiding the card, a plant mounting plate mounted on the slant support block, an imprinting roller for imprinting embossed characters of the card on the sales slip, a roller drive unit for reciprocating the imprinting roller together with a roller support bracket, a printer head for printing other items on their respective blanks of the sales slip after imprinting of the embossed characters on the sales slip, and a sales slip feed sensor mounted on the support block in order for checking a feeding operation of the sales slip.

Abstract: A card reader having an antiabrasion member for preventing a bottom surface of a card checking passage of the card reader from card contact abrasion. This antiabrasion member is easily inserted in a mold before an injection molding of a main body of the card reader and prevented from displacement in the mold, and allows a magnet head to be easily changed with new one to provide a good compatibility of the magnet head. The plurality of notches prevents the antiabrasion member from being horizontally displaced in a mold and are provided at both sides of the member, and engage with individual ribs of the mold when the member is located in the mold. The slit is provided as a result of lateral cutting of the member between the notches. The resilient part integrally extends from a side of the member near the slit and allows the slit to be inserted in a rib of the mold, and prevents the member from being vertically displaced in the mold.

Abstract: A noise-shielded transformer is constructed with a toroidal core having mounted thereon a secondary winding, a bifilar shield winding, a conductive plate, an insulating member, a high voltage winding, and a primary winding. The secondary winding is located inside the other windings, making the assembly work easier and increasing the noise shielding effect. Multiple shielding, by the bifilar shield winding and the conductive plate, increases the capacitance between the secondary winding and ground and decreases the capacitance between the primary winding and the secondary winding, so that the noise eliminating characteristic with respect to pulse-property noise and high frequency-property noise is enhanced substantially. It is also possible to obtain a grounding effect and a noise-bypass effect by connecting a resonance condenser from ground to one end of the bifilar shield winding.

Abstract: A noise-shielded transformer which suppresses electrical noises by absorbing conductible electrical noises that flow into the power line to cause interference, consisting of a gapless-type toroidal core, a primary winding and a secondary winding uniformly wound after dividing the entire magnetic path of the toroidal core in two, and conductive plates mounted to wrap the primary winding and secondary winding, respectively, wherein conductive plates are mounted in the gap of the toroidal core to magnetically isolate the primary winding and the secondary winding, conductive plates are mounted outside the gap of the toroidal core and the gapless-type toroidal core has a configuration of continuously winding steel shield of directional silicon.
