BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette loading device for a recording/reproducing apparatus using a tape cassette.

0003

[Prior Art] Conventionally, a video tape recorder (VTR)
In a recording/playback device such as a digital audio tape recorder (DAT), a tape cassette is stored in a cassette holder through a cassette insertion slot, transported horizontally toward the inside of the device, and then transported vertically downward.
The cassette is placed on a predetermined reel stand and cassette loading is completed. On the other hand, when discharging a loaded cassette, the cassette is conveyed vertically upward from a predetermined reel table, then conveyed horizontally toward the cassette insertion opening, and then ejected from the cassette insertion opening by a cassette pushing member. Ru.

In such conventional cassette loading devices, the lid must be completely opened when the cassette is placed on a predetermined reel stand. Therefore, a lid opener is provided on the base casing or the side frame, and when the tape cassette is conveyed vertically downward, the lid is opened by locking the lid with the lid opener.

However, in this method of opening the lid, the tape cassette must be conveyed vertically downward over a long distance, making it difficult to shorten the loading time and make the device thinner.

In response to this, a device has been developed in which a pre-opener is provided in the cassette holder to open the lid of the tape cassette to some extent before the tape cassette is conveyed vertically downward.

FIGS. 20 to 22 show a cassette loading device using such a pre-opener, FIG. 20 is a side view when the cassette holder is being retracted, and FIG. 21 is a side view when the cassette holder is in the loading completion position. It is a diagram.

In FIG. 20, a cassette loading device 71 has a cassette holder 7 containing a tape cassette.
2 is supported by left and right side frames 73a, 73b so that it can be pulled in, discharged, and moved up and down.

A pre-opener 74 is provided on the bottom right side of the cassette holder 72. On the other hand, a lid opener 75 is provided on the left side frame 73a.

[0010] The pre-opener 74 is formed by bending a metal plate, and has one end fixed to the back right side of the bottom surface of the cassette holder 72, and the other end bent upward to accommodate the tape inserted into the cassette holder 72. Cassette 51 (Figure 2
