It is easy to pull out the tape from the cassette, and it is small! It must be robust in quantity.

In order to meet such demands, cassettes 1 to 10 that are vertically expandable and retractable have become popular.

FIG. 1 is an explanatory diagram of the cassette house.

The cassette house 1 is composed of a cassette case 3 having an opening on the side surface for taking in and taking out the cullet 2, and an outer part 4 for storing the force L and the case 3. power supply 1
When inserting ~2 into cassette 1 and 3, or when inserting cassette case 3
If you do not take it out from the cassette 1, the house will be made into a two-story building. The poem cassette] - Harns is stretched up and down, cassettes 1 to 3 are on the second floor, and external 4 is on the first floor. After inserting the cassette, when the roof 5 is pushed down, the cassette case 3 descends together with the cassette 2 and is housed in the outer shell 4.

While the cassette case is falling, the tape cover 2 of the cassette
a is unlocked and opened to expose the tape and the cassette (
- The tape reel covers the reel stand fixed to the bottom plate of the cassette house 1 six times, and at the same time the reference pin 6a determines the position of the cassette 2.

External 4 is one side for pulling out the tape (J3 in Figure 1).
The outside is closed except for the front side. There are various structures for raising and lowering Case 3 (2nd floor). In FIG. 1, J3 shows an X-shaped lifting device which is commonly used for the above purpose. This is a bar 7 mounted rotatably around an externally fixed rotation @7Δ.
and a bar 8 which is rotatably mounted around a rotating shaft 8a fixed to the cassette 1 to case 3, and intersect each bar 7 and 8. 1t17b and 8b are covered so as to be able to move once along the horizontal long grooves 7c and 8G provided on the outer 4th part of the 11 cassette coils 3, respectively.
