Is moved together with the holder in a direction parallel to the main surface of the disc stored in the cartridge, transported to the position facing the mounting part, and then moved in a direction perpendicular to the main surface of the disc Operated and mounted on the mounting part. Also, when performing an eject operation for ejecting the disk cartridge mounted on the mounting portion to the outside of the apparatus main body, the loading mechanism first mounts the disk cartridge. Move it in the direction perpendicular to the main surface of the disk to separate it from the mounting part, then move it with the holder in a direction parallel to the main surface of the disk, and move it to the insertion / exit side. Move.
- a slot-in type recording / reproducing apparatus in which a disk cartridge is operated through a slot provided in the main body of the apparatus to perform a mouthing operation.

- this type of recording / reproducing device only the insertion and exit of the disk cartridge, which is approximately equal in thickness and width, is provided. Unable to pull out the disk trigger. Therefore, when ejecting a disk cartridge mounted on the mounting section in the main body of the device, at least a part of the disk force trigger must be removed. It is necessary to protrude out of the main body of the device through the b to enable grasping with fingers.
- the disk cartridge In this way, in order to allow a part of the disk cartridge to be exposed to the outside of the main unit through the opening during the eject operation, the disk cartridge It is necessary to increase the moving range of the holder that holds and holds the disk cartridge and feeds and operates the disk cartridge. As a result, the recording / reproducing apparatus itself becomes large.
- the disc cartridge when ejecting, the disc cartridge is projected out of the device body by using the bias of the panel, so that the disc cartridge can be pushed out of the device body.
- a recording / reproducing device that protrudes from the holder is used.
- the disk cartridge is mounted using springs in this way.
- the recording / reproducing apparatus which protrudes outward from the main body, moves the holder to a certain position on the inner side of the main body, and uses the urging force of the panel from the position where the holder is stopped.
- the disk cartridge is protruded outward from the main body of the device. Therefore, in this recording / reproducing apparatus, it is possible to reduce the moving range of the holder and realize the miniaturization of the apparatus itself.
- the surface condition and the external shape of the disk are not limited. Due to deformation, etc., the amount of protrusion from the insertion / removal port will not be constant. Also, if the urging force of the panel that urges the disk cartridge is too large, the disk cartridge will suddenly protrude from the opening when ejecting, and The screw will pop out of the machine. A loading device with a brake mechanism is also used to prevent such a steep disc cartridge from popping out.However, the mechanism becomes more complicated. It is difficult to set the brake force of the panel and the brake mechanism that bias the disk cartridge to an appropriate level, and it is necessary to perform a stable operation of ejecting the disk cartridge. I can't do it. Disclosure of the invention

- the cartridge 220 or 222 is rotated in a direction to protrude from the cartridge holder 4. Due to the rotation of the electronic tray 98, the disc cartridges 22 or 21 partially protrude from the insertion / removal opening and are grasped by fingers. The cartridge can be pulled out from the cartridge holder 4. The eject operation is completed by pulling out the disk cartridge 22 or 21 from the outlet.
- a recording medium loading device includes: a cartridge holder for holding a disk cartridge used as a recording medium for an information signal; and a cartridge holder.
- a lifting operation mechanism including a lifting operation plate that moves the cartridge holder up and down with respect to the mounting part is selected by the rotating body and the moving operation mechanism that rotates this rotating body according to the position of the cartridge holder.
- the mechanism is simplified and the size of the apparatus itself can be reduced. As a result, the size of the recording and / or reproducing apparatus provided with the loading device can be reduced.
