Abstract

(57) [Summary] [Object] To provide a cassette holder that is locked to the chassis even when the side opposite to the lock lever of the cassette holder is pressed. [Structure] Attached to a cassette holder 11 are levers 22 and 23 that are rotatably supported, and the levers 22 and 23 are engaged with each other at their one ends. The pressure is transmitted to the cassette holder 11 via the lever 23.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cassette holder to which a cassette used in a video tape recorder (VTR) or the like is mounted and which moves the cassette between a mounting position and a predetermined recording / reproducing position.

[0002]

[Prior Art]

 FIG. 4 shows a cassette holder that has been conventionally used in an 8 mm VTR. In FIG. 4, the main chassis 1 is provided with a cylinder 2 on which a rotary head is mounted, a tape pull-out member 3 for winding a magnetic tape around the cylinder 2, a tape guide 4 and a motor 5. On the other hand, the sub-chassis 6 slidably attached to the main chassis 1 is provided with reel shafts 7 and 8 which engage with reels of a cassette. The side plates 9 and 10 of the sub-chassis have links 13 and 14, one end of which is pivotally supported by the side plates 9 and 10 and the other end of which is slidably engaged with a long hole 12 formed in the cassette holder 11. , One end slidably engages with the long hole 15 of the side plates 9 and 10, and the other end has links 16 and 17 pivotally supported by the cassette holder 11 so that the cassette holder 11 can be lifted and lowered. ing.

Further, the cassette holder 11 is biased by a spring 18 stretched between the link 13 and the link 16 and between the link 14 and the link 17 so that the cassette holder 11 is held at the cassette mounting position. ing.

A lock lever 20 is rotatably attached to the cassette holder 11 by a shaft 19. This lock lever 20 is attached to a pin 21 provided on a link 17 that moves in the direction of arrow A when the cassette holder 11 is lowered to the recording / reproducing position by the operator's hand or the like, as the cassette holder 11 descends and descends. By engaging, the cassette holder 11 is locked at the recording / reproducing position.

[0005]

[Problems to be solved by the device]

 In the above conventional technique, the operator does not press the upper part of the cassette holder where the lock is provided, but if the operator presses the opposite side, the cassette holder is urged toward the upper cassette mounting position. There was a problem that the cassette holder was deformed and it was difficult to lock it.

[0006]

[Means for Solving the Problems]

 The present invention relates to a cassette holder in which a cassette is mounted at a cassette mounting position, holds the cassette between the cassette mounting position and a recording / reproducing position, and is engaged with the chassis at the recording / reproducing position. Two levers are rotatably supported, one end of each lever is formed with a pressing portion, and the other end is engaged with each other. When the pressing portion of one lever is pressed, it is pressed. When the lever is rotated, the other lever is also rotated, and the pressing force is transmitted to the cassette holder via the other lever.

[0007]

[Action]

 According to the present invention, even if the pressing portion of the cassette holder opposite to the lock lever is pressed, the pressing force is transmitted to the lock lever side of the cassette holder via the lever.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Further, the same parts are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 shows a perspective view of the present embodiment, in which the levers 22 and 23 are rotatably attached to the cassette holder 11 by shafts 24 and 25, and a pin is set up at one end of the lever 22. 26 is slidably engaged with an elongated hole 27 formed at one end of the lever 23. Further, pressing portions 28 and 29 are provided at the other ends of the levers 22 and 23.

FIG. 2 shows a front view of the cassette holder at the cassette mounting position where the cassette holder 11 is raised. In the figure, the lock lever 20 is on the right side of the cassette holder 11, and when the operator presses the pressing portion 28 of the lever 22 on the side opposite to the lock lever, the lever 22 rotates around the shaft 24 in the direction of arrow B. The lever 23 is moved and pivoted in the direction of arrow C by the pin 26 engaged with the long hole 27 of the lever 23, and the state shown in FIG. 3 is obtained.

Therefore, when the pressing portion 28 of the lever 22 is further pressed from this state, the pressing force is transmitted from the lever 22 to the lock lever 20 side of the cassette holder 11 by the back surface of the pressing portion 29 via the pin 26 and the lever 23. The same as when pressing the lock lever 20 side of the cassette holder 11.

With the above configuration, even if the pressing portion of the lever on the side opposite to the lock lever side of the cassette holder is pressed, the pressing force is transmitted to the lock lever side, and the cassette holder is securely locked at the recording reproduction position. can do.

[0012]

[Effect of the device]

 According to the present invention, the cassette holder can be locked at the recording / reproducing position even if the pressing portion on the side opposite to the lock lever side of the cassette holder is pressed.
