Claims

[Scope of utility model registration request]

a cam plate that changes the cartridge holder according to sliding displacement between an insertion position where a disk cartridge is inserted and a mounting position where a disk in the disk cartridge is mounted on a turntable;
a first lever member that engages with the cam plate to restrict sliding displacement of the cam plate when the cartridge holder is in the insertion position; At the same time, the second disk cartridge presses and urges the disk cartridge in the detachment direction.
A lever member is provided on the first lever member so as to be able to engage with the second lever member, and is engaged and pushed by displacement of the second lever member, thereby causing the first lever member to engage with the second lever member. an engagement release member that disengages the cam plate from the engagement with the second lever member; A disk cartridge attachment/detachment mechanism comprising a displacement regulating member that engages with an engagement release member and regulates displacement of the second lever member.
