Abstract

PURPOSE:To unlock a lid without operating a VTR with the lid locked, prevent the VTR from malfunctioning, and improve the operativity by providing a lever which presses an unlocking part associatively with a cassette when the cassette is inserted securely. CONSTITUTION:When the cassette 1 is inserted to a prescribed position, the front surface of the cassette 1 abuts on a projection piece 16, a projection piece 17 presses and turns on a detection switch 18, and the 1st arm 9 rotates around a rotating shaft 8 into a cassette receiving metallic fixture 5 to press the unlocking part 3. Consequently, the cover 2 is unlocked. Thus, the malfunction of the VTR is prevented and the operativity is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The field of industrial application of the present invention is a cassette video tape recorder (hereinafter referred to as VTR).
It is abbreviated as This invention relates to a cassette mounting device for mounting a cassette of 1.).

Conventional structure and problems thereof FIG. 1 is an external perspective view of a cassette mounted on a VTRK. In Fig. 1, 1 is a cassette, 2 is a lid provided on the front of the cassette 1, 3 is a lock release part of the lid 2 provided on the side of the cassette 1, and 27, -70 press the lock release part 3. By doing so, the closed state (hereinafter referred to as "lock") of the lid 2 is released. Arrow 4 indicates the direction in which the cassette 1 is inserted into the VTR.

Conventionally, when the cassette 1 is inserted into a VTR, the cassette holder that holds the cassette 1 is pressed by a leaf spring or the like (not shown) so as to press the lock release part 3 against the side surface of a metal fitting (not shown). The parts were fixed.

However, in the conventional configuration described above, if the cassette 1 is inserted in a direction slightly different from the normal direction, the lock release part 3 is not pressed and the lid 2 remains locked and cannot be opened and must be reinserted. It had

OBJECTS OF THE INVENTION It is an object of the present invention to provide a cassette loading device that unlocks the cassette lid and securely mounts the cassette when loading the cassette into a VTR.

Structure 3 of the Invention The present invention includes a cassette having a lid on the front and a lock release part on the side that releases the closed state of the lid by pressing, and the cassette is installed in a predetermined position in a video tape recorder. The cassette is configured to include a lever that presses the lock release section when the cassette is inserted into the predetermined position, thereby making it possible to reliably release the closed state of the lid when the cassette is inserted into the predetermined position. can.

DESCRIPTION OF EMBODIMENTS A cassette loading device according to an embodiment of the present invention will be described below with reference to FIGS. 2 and 3. Identical members in FIGS. 2 and 3 are designated by the same numbers.

In FIGS. 2 and 3, reference numeral 5 indicates a metal fitting for holding the cassette 1 (not shown in FIG. 2); reference numeral 6 indicates a lock release hole provided on the side surface of the metal fitting 5; and 7
The cassette holder is fixed to the rear end 6a of the metal fitting 5 so that its center can be rotated around a rotating shaft 8, and the cassette holder has a first arm 9 formed by bending the side surface of the metal fitting 5, and the cassette holder is attached to the metal fitting 5. 5 and a second arm 1o extending rearward; 11 is a V lever;
A spring 14 that holds the lever 7 in the one-leg position, which has one end locked to the fixing member 12 in the TR and the other end locked to a locking piece 13 provided approximately in the center of the first arm 9; is the first
The second arm 1o is provided at the tip of the arm 9 and the second arm 1o is indicated by an arrow 16.
16 is a second arm 10 that is provided so that when pushed in the cassette insertion direction shown by , it protrudes into the hole 6 with the rotating shaft 8 as a fulcrum and presses the lock release part 3 when the cassette 1 is installed. A protrusion piece 17 is provided at the tip of the second arm 10 and comes into contact with the front surface of the cassette 1 when the cassette 1 is inserted into the receiving fitting 5, and the cassette 1 is inserted into a predetermined position. This is a protruding piece that is pressed to turn on the detection switch 18 when the cassette 1 is inserted into a predetermined position.

With the above configuration, when the cassette 1 is inserted into a predetermined position, the front surface of the cassette 1 comes into contact with the protruding piece 16, and the protruding piece 17 presses the detection switch 18 to turn it on, and the rotating shaft 8 is turned on. The first arm 9 rotates the cassette holder in the direction inside the metal fitting 5, and
Press the lock release part 3. This unlocks the lid 2.

As described above, according to this embodiment, since the lever 7 is provided which presses the lock release part 3 in conjunction with the cassette 1 when the cassette 1 is inserted into a predetermined position, the insertion of the cassette 1 is ensured. When the detection switch 18 is turned on, the protrusion piece 14 provided at the tip of the lever 7 presses the lock release part 3 to release the lock of the lid 2 and release the lock of the lid 2. This can prevent malfunctions of the VTR and improve operability.

Effects of the Invention As described above, according to the present invention, when the cassette is inserted reliably, a lever is provided that presses the lock release part in conjunction with the cassette, so that the lid can be operated without being locked. The lid can be unlocked without any trouble, preventing malfunctions of the VTR and improving operability, which is highly effective.
