Abstract: A support pin—which is to be inserted into a pin insert hole formed in a seed rod provided at an upper end of a glass preform and suspends and supports the glass preform—is formed by coupling a pin main body having a flange section, a first shaft section, a second shaft section, and a male screw section with an auxiliary pin member having a flange section, a shaft section, and a female screw section. The first and second shaft sections of the pin main body and the shaft section of the auxiliary pin member are provided with claddings which are formed from synthetic resin and have elasticity. The support pin is formed so that the second shaft section of the pin main body covered with the cladding can be inserted into the pin insert hole formed in the seed rod.

Abstract: An apparatus for feeding and discharging of the recording paper printed over the entire page is disclosed. A pair of paper guide members are disposed in the vicinity of the lateral ends of the ink ribbon drawn from the ribbon outlet port respectively so as to project from the wall plate of the cassette body in the direction in which the ink ribbon is drawn. The pair of paper guide members is formed with a surface inclined in such a manner that the projecting length decreases from the projecting top to the base of the paper guide member toward the lateral center of the wall plate.

Abstract: The invention intends to enable proper feeding and discharging of the recording paper printed over the entire page without causing deterioration of the quality. A pair of paper guide members are disposed in the vicinity of the lateral ends of the ink ribbon drawn from the ribbon outlet port respectively so as to project from the wall plate of the cassette body in the direction in which the ink ribbon is drawn. The pair of paper guide members is formed with a surface inclined in such a manner that the projecting length decreases from the projecting top to the base of the paper guide member toward the lateral center of the wall plate.
