Abstract: A natural rubber-containing thermoplastic resin composition includes a graft copolymer (A) obtained by graft-polymerizing a vinyl monomer mixture (a) including at least an aromatic vinyl monomer to a rubbery polymer (R) composed of 10 to 70% by mass of a natural rubber having a weight average particle size of 0.3 to 1.2 ?m and 30 to 90% by mass of a synthetic rubber having a weight-average particle size of 0.2 to 0.4 ?m, wherein particles of the natural rubber include not less than 5% by mass of natural rubber articles with a size of 1.0 ?m or larger; and particles of the rubbery polymer (R) with a size of 1.0 ?m or larger have an internal graft ratio of 20% or higher.

Abstract: An apparatus for derailing with a passbook having a plurality of data recording surfaces, includes a passbook recording unit in which data is recorded on the recording surfaces of the passbook introduced in a conveying passage of the apparatus via an access opening. A plurality of new passbook storing boxes are arranged along the conveying passage, and a passbook detector for detecting the presence or absence of new passbook is provided in each passbook storing box. When all spaces in the data recording surfaces of the passbook received in the conveying passage are used up, a new passbook is supplied from one of the storing boxes to the conveying passage, so that the remains of data is recorded on the data recording surfaces of the new passbook by the recording unit.
