Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette recorder using a cassette with a lid.

Conventional configurations and their problems In recent years, cassette recorders have come to be widely used in fields other than the audio field. In addition, the performance of cassettes for audio applications has continued to improve, and cassettes with lids have become desirable in order to prevent fingerprints, dust, etc. from getting on the tape inside the cassette. Conventional tape cassettes have the tape peeking out of the opening, so there are problems with fingerprints, being bent by fingertips, and dirt and dust sticking to the tape, which is the cause of so-called 1. It had become.

Purpose of the Invention In order to solve the above-mentioned conventional problems, the present invention (d) provides a new method that enables automatic opening of the cassette lid, which is necessary when using a tape cassette with a lid, which the authors have already proposed. An object of the present invention is to provide a cassette recorder having a cassette insertion guide device.

Structure of the Invention The present invention relates to an opening of a cassette body having an opening on one side.
A cassette recorder using a cassette that can be opened by pulling the U-shaped lid, which opens and closes by rotating the part downward, in the closed state from the opening surface of the force cell 1 in a vertical direction. It consists of an insertion guide means for guiding the insertion of the cassette in the main plane direction, a U-shaped lid backward pressing means provided on the side of the insertion guide means, and a cassette insertion detection means also provided on the side. Since this cassette recorder has a cassette insertion guide device that performs the pressing operation of the U-shaped lid rear pressing means in conjunction with the detection operation of the insertion detection means, the load during insertion is extremely small, and the load at the end of insertion is extremely low. Since the U-shaped lid is suppressed backwards and the lid is released from the closed position, the next movement of the cassette insertion guide device to the predetermined performance position, that is, generally in the cassette insertion direction. This enables automatic opening during a so-called seso tink operation in a direction substantially perpendicular to the direction. Therefore, compared to a device that performs both unlocking and automatic release operations during the setting operation, the moving distance 1 required for setting can be extremely reduced, and the device can be made thinner.
