Abstract: A tape cassette loading device in a tape recorder has an improved structure for smooth insertion of a cassette without resistance from a plate spring. The loading device includes plate spring members fixed at left and right sides of a holder, and a chassis installed on the upper part of the holder and having cam portions engaged with the plate spring members. When the holder is at an inserting position of the cassette, the plate spring members do not engage with the cam portions. Therefore, when the cassette is initially inserted into the holder, the cassette can be inserted into the holder without any resistance from the plate spring members.

Abstract: A pole base moving apparatus of a tape recorder in which the link structure of a pole base which pulls out a magnetic tape from a tape cassette to a head drum is provided. The pole base moving apparatus includes a slide member which has a reciprocating motion produced by a motor and in which moving slots of a predetermined pattern are formed and first and second link members whose one ends are respectively combined with a pair of pole bases and the other ends of which have protrusions which respectively enter and exit the moving slots. Accordingly, it is possible to simplify the structure compared with the conventional technology, thus simplifying the assembly process and reducing the number of the parts and manufacturing costs.

Abstract: A cassette loading apparatus for a cassette player, the apparatus includes a guide protrusion which is rotatably connected with the holder so as to be moved up and down, and with which is capable of connecting a reel hub of the tape reel, and a connection driving body having a connection portion capable of connecting the reel driving table, wherein the connection driving body is connected with the reel driving table when the cassette is loaded, and at the same time is elevated, so that the connection driving body is connected with the reel hub of the tape reel. Thus, the apparatus can avoid the inferior loading of the cassette and minimize noises generated during cassette loading operations.
