Title:
媒体を検出するための方法および装置
Document Type and Number:
Japanese Patent JP3983758
Kind Code:
B2
Abstract:
A media detection system (10) includes a light source (34) mounted within a cartridge receiving chamber (14) defined by a cartridge engaging assembly (16). A cartridge referencing member (24) has an arm portion (26) mounted to the cartridge engaging assembly (16) and a head portion (28) located within the cartridge receiving chamber (14) at a position adjacent the light source (34). The cartridge referencing member (24) is deflected by a data cartridge (12) within the cartridge receiving chamber (14) so that the head portion (28) does not block light (38) produced by the light source (34) when a data cartridge (12) is located within the cartridge receiving chamber (14). When no data cartridge is located within the cartridge receiving chamber (14), the cartridge referencing member (24) is not deflected and blocks substantially all light (38) produced by the light source (34). A detector assembly (36) mounted within the cartridge receiving chamber (14) detects whether light (38) from the light source (34) is blocked or not blocked.
