Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette tape recorder having a cassette autochanger function.

Generally, in a cassette tape recorder, a cassette selected as necessary is loaded into the cassette loading chamber number ζ to perform recording and playback operations. When replacing this cassette, operate the eject operation button or the like to pull out the cassette from the cassette loading chamber.

Thereafter, the newly selected cassette must be loaded into the cassette loading chamber.

When continuous playback (recording) is performed using this tape recorder, the operations of picking, loading, and playing (recording) each tape must be repeated, making replacement extremely troublesome.

On the other hand, a cassette tape recorder has been devised that is equipped with a cassette autochanger that stacks a plurality of cassettes vertically and utilizes the force of gravity to continuously reproduce and play bells. This device sequentially attaches and detaches cassettes by moving the drive mechanism up and down.When a bell or playback operation is performed with multiple cassettes loaded in the cassette holder, the drive mechanism moves upwards and the capstan shaft Cassette)
[Hamaru. When the next stop operation is performed, the drive mechanism sinks downward and the capstan shaft is disengaged from the cassette, and at the same time the cassette is pushed sideways and falls into the cassette reservoir.

However, in this case, the cassette receptacle must be installed in the tape recorder itself, which is disadvantageous in terms of miniaturizing the entire device, and the mechanism is complicated, which is disadvantageous in terms of cost reduction. Therefore, it is not possible to arbitrarily select the cassette installed in the cassette holder.

Also in the cassette loading room! ! Since the loaded cassette is stored in a cassette reservoir, if the same 71st operation is to be repeated again, the cassette holder must be removed, making the operation very cumbersome.

This invention was made in order to solve the above problems, and the insertion opening of the cassette loading chamber of the slot incubator provided in the main body of the cassette tape recorder is opened in the front panel of the main body. A cassette holder storing a plurality of cassettes in a loadable manner is removably and slidably mounted on the front panel of the main body, and is slid by a drive device to select a stop position of the cassette holder by an output signal from a selection operation button. The object of the present invention is to provide a cassette tape recorder that can automatically select a desired cassette by detecting the stop position of the cassette holder via a sensor and turning off the drive motor by a control device.
