ーキ装置。[Claims for Utility Model Registration] (1) A pair of brakes 23 and 24 mutually biased and supported by a spring 27 are installed in front of the supply reel 21 and the take-up reel 22, and a board 50 in front of these brakes 23 and 24 is installed. A reel brake device for a video tape recorder in which an operating plate 29 is swingably inserted and guided by a guide pin 28 fixed above, and a cam gear 30 meshes with a worm 44 connected to a pulley 43 of a drive motor 40. A connecting lever 32 is rotatably fitted into a shaft pin 31 fixed on the base plate 50 below the cam gear 30, and a long hole 3 is inserted into the base end portion of the connecting lever 32.
2a and insert the actuating plate 29 into the elongated hole 32a.
An actuating pin 29b protruding from one end of the cam gear 30 is swingably inserted into the coupling lever 32, and a coupling lever 32 has a coupling lever 32 at the other end which abuts and is guided by a cam groove 30a formed on the bottom surface of the cam gear 30. A pin 32b is provided in a protruding manner, a hooking portion 32c is formed as an extension at the tip of the other end adjacent to the connecting pin 32b, and the base end of the foot lever 33 is rotated around the shaft pin 34 fixed on the base plate 50. The foot lever 33 is biased and supported by a torsion spring 35 which is movably fitted and whose base end is fixed on the base plate 50;
A hooking portion 33 with which the hooking portion 32c of the connecting lever 32 is engaged with the tip of the hook lever 33.
a, and a pressing piece 33b is formed at the rear of the proximal end of the foot lever 33, and a fixing piece 38 fixed on the base plate 50 at an approximately intermediate position between the foot lever 33 and the drive motor is attached to the center of the main body. A hit lever 36, which has a long hole 36b drilled therein, is attached freely by a fixing pin 39 while passing through the long hole 36b. The base end of a plate spring 37 is fixed on the lower base plate 50 of the cam gear 30 and has a locking portion 37a that locks the hook portion 334 of the foot lever 33 when sudden braking is applied. A video tape recorder reel sudden braking device characterized by: (2) The cam groove 30a of the cam gear 30 operates at an operating point A in the stop mode and an operating point at which the locking portion 33a of the hook lever 33 locked to the locking portion 37a of the plate spring 37 is released to prepare for the next mode. B, operating point C for entering fast forward/reverse mode, operating point D for performing fast forward/reverse mode, and sudden braking action when converting from fast forward/reverse mode to stop mode. A reel sudden braking device for a video tape recorder as set forth in claim (1) of the utility model registration, characterized in that it comprises an actuation point E and an actuation point F for entering the play mode. (3) Utility model registration claim (1) characterized in that an inclined surface 29a is formed on one side of the upper surface of the operating plate 29 so that the protrusion 24d of the take-up reel side brake 24 can be directly pressed. The videotape recorder reel sudden braking device described. (4) A protruding piece 36a that is pressed by the pushing piece 33b of the foot lever 33 is formed at one end of the hit lever, and a locking step 43a formed on the pulley 43 of the drive motor 40 is formed at the other end.
