Disk cartridge shutter door opener

摘要

An opener for opening the shutter door of a disk cartridge. The opener includes an opener beam having a slot section and a pin that passes through the slot section of the opener beam to be fastened onto a base metal plate. Therefore, the opener beam is able to slide with respect to the fixed pin within the opener slot. A first slot is also formed in the base metal plate so that a slider attached to the head section of the opener beam is able to slide freely inside the slot. In addition, the opener has a spring with one end fastened to the base metal plate while the other end is fastened to a spring lock pin of the opener beam. A second slot on the base metal plate permits the spring lock pin to slide inside the slot. In an alternative design, by using pins that fasten onto the base metal plate, there is no need to form first or second slots on the base metal plate.
