Description

[Detailed description of the invention] Industrial applications The present application relates to a cassette tape player.

Conventional technology and its problems Conventionally, a cassette is mounted in a cassette holder, which is constructed by connecting a front frame that can move vertically in a horizontal state to the front end of a rear frame whose rear end sides are supported by a container frame and which can tilt vertically. When the cassette is fully inserted into the cassette holder, a part of the cassette will engage with the 4-frame side 6. The horizontally rotatable holding member that holds the rear frame of the cassette holder in a horizontal state is rotated, and this rotation releases the locked state and allows the cassette holder to move downward. In addition, when the eject lever moves the cassette holder upward during an eject operation, the holding member horizontally rotates and a part of the holding member is locked to the side edges of the four frames. For example, a cassette type tape tape having a tape configuration so as to maintain a horizontal state is disclosed in Japanese Patent Application Laid-open No. 60-1.
