Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette half mounting device in a cassette deck.

Conventionally, as a device for attaching and detaching a cassette half in a cassette deck, for example, a head cover for preventing dirt intrusion that is attached to the front of the cassette storage section is opened, and the cassette half is attached to a shaft that protrudes into the cassette storage section.
Since the cassette halves were to be stored, it was time-consuming to attach and detach the cassette halves.

The present invention has been made in view of the above-mentioned points, and its purpose is to directly attach a cassette half to a make-up plate which is designed to cover and protect the deck body at all times, without providing a head cover. Detachable and non-detachable,
Moreover, when the cassette half is not loaded, the make-up plate engages with a clamper provided in the lower part of the cassette storage part, thereby preventing dust from entering the cassette deck main body. It is in.

Hereinafter, details of an embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a cassette deck main body, 2 a cassette storage section provided in the cassette deck main body 1, and 3 a makeup plate pivotally attached to the cassette storage section 2 by a spade 5 via a torsion spring 4. The lower front surface thereof is pressed and engaged with the engagement protrusion 6a of the clamper 6 disposed on the lower edge of the cassette storage portion 2.

Reference numeral 7 denotes insertion holes drilled in parallel on the front surface of the makeup plate 3, and the cassette deck main body 1 is inserted into the insertion holes 7, 7.
The reel shafts 8, 8 are loosely inserted.

9 has one end fixed to the cassette deck main body 1 and the other end formed above the makeup plate 3. , 3a.

The clamper 6 is pivotally connected to a lever 14 by a pin 13, and has an engaging protrusion 6a formed on the front upper surface thereof at the rear of the sliding slope 6a, with which the lower front surface of the cassette half A can be engaged. A tension spring 15 is interposed between the rear end projection 60 of the raised bar 6b and the lever 14. 1
Reference numeral 6 denotes a fixed frame to which the lever 14 is pivotally connected with a pin 17 and fixed to the cassette deck main body 1.

Reference numeral 18 denotes a tension spring inserted between the rear end protrusion 14a of the lever 14 and the fixed frame 16, and the tension spring 18 urges the front part of the lever 14 in the direction of rising.

Reference numeral 18a designates a head, and reference numeral 19 designates a stopper provided in the cassette storage portion to abut the clamper 6 and makeup plate 3 to prevent dust from entering.

One embodiment of the present invention is constructed as described above, and when the cassette half A is not loaded, the makeup plate 3 engages with the engagement protrusion 6a of the clamper 6 arranged in the lower green part of the cassette storage section 2. Furthermore, since the clamper 6 and the makeup plate 3 are engaged with the stopper 19, the cassette storage section 2 is closed, thereby preventing dirt and the like from entering the cassette deck body 1. It protects parts such as 18a.

When loading the cassette half A, first the upper surface of the cassette half A is sandwiched between the plate springs 9, 9 and supported elastically, and the lower surface of the cassette half A is slid into contact with the sliding slope 6a of the clamper 6. Let the tension spring 15,
The clamper 6 is pivoted and lowered together with the lever 14 using the pin 17 as a fulcrum against the elastic force of the torsion springs 4, 4, and the make-up plate is moved around the shaft 5 against the elastic force of the torsion springs 4, 4. 3 to the rear and push in the cassette half A. As a result, the clamper 6 pivots around the pin 13 due to the restoring force of the tension spring 15 and returns to its original position, and the lever 14 also returns to its original position using the pin 17 as a fulcrum due to the tension spring 18, so that the engagement protrusion 6a engages with the lower front surface of the cassette half A, and as shown in FIG. Can be loaded. To remove the cassette half A from the makeup plate 3, push down the clamper 6 using the pin 13 as a fulcrum against the elastic force of the tension spring 15.
The lever 14 supporting the clamper 6 also pivots about the pin 17 against the tensile force of the tension spring 18, thereby disengaging the cassette half A from the engagement protrusion 6a of the clamper 6. At the same time, the upper surface of the cassette half A is released from the elastic support of the leaf springs 9, 9, and the cassette half A is taken out from the makeup plate 3.

When the cassette half A is removed from the make-up plate 3 in this way, the clamper 6 is restored by the elastic force of the tension spring 15 using the pin 13 as a fulcrum, and the lever 14 is also activated by the elastic force of the tension spring 18 using the pin 17 as a fulcrum. Restoration to old position by force. Then, the make-up plate 3 returns to its original position around the shaft 5 due to the elastic force of the torsion spring 4, and its lower front surface engages with the engagement protrusion 6a of the clamper 6, returning to the state shown in FIG. . As described above, the present invention allows the cassette half to be directly attached to and removed from the make-up plate which covers and protects the deck body at all times, and when the cassette half is loaded, the make-up plate is attached to the cassette storage part. By pressing against the clamper provided on the lower edge of the cassette deck, it is effective to prevent dirt from entering the cassette deck body.

Claims (1)

[Claims] 1 When the cassette half is not loaded, the make-up plate pivoted inside the cassette storage section is energized by the elastic force of the spring and engages with a clamper placed at the lower edge of the cassette storage section to close the cassette storage section. The cassette half mounting method is characterized in that, during loading, a spring elastically supports the upper surface of the cassette half, and the lower front surface of the cassette half is engaged with the clamper to directly load the cassette half onto the make-up plate.
