49、hanism PCB1) This mechanism permits the re-loading of a cartridge afterit has been ejected.2) A cartridge cannot be inserted during power-off due to built-in automatic push-out cartridge (This is for preventing thebreakage of the mechanism).1. Configuration of main componentsThis mechanism consists of main components as shownin the figure below.The main purpose of the traverse chassis assembly ( 1 )is to hold a cartridge and read its signals form it.The main purpose of upper chassis assembly ( 2 ) andloading arm assembly ( 3 ) is to mechanically pull in and pushout a cartridg
