Title: Housing device of tape recorder
Inventor: SAI MICHINAGA
IPC: G11B15/675
Filed: 1993-12-02
Abstract: PURPOSE: To smoothen the operation of a tool without using a motor by continuously executing the loading and eject operations of a cassette tape by a lever housing opened and closed in a hinge system. CONSTITUTION: A lever housing 20 operates the rotating motion of a first pin 21 of the lever housing 20 connected with a long hole 12 of a main deck 10 with a second pin 22 as a reference hinge point. Therefore, the lever housing 20 operates the additional rotating motion only at θ2 so that a cassette holder 40 can be taken away. On the other hand, when the descending operation of the lever housing 20 is executed only at θ2 after the cassette tape is inserted into the cassette holder 40, the cassette holder 40 is moved inward from the upper part of a housing 30, and the loading can be completed. In this case, the descending operation is executed further at only θ2 so that the cassette tape can be stabilized in the main deck 10.
