頼性消費電力或はスペースファクター等々の点でマイナ
スとなる点が多い。In order to reduce the operating torque in VTRs and the like that employ mechanical push button operating mechanisms, and to avoid complicating the mechanical configuration, it is conceivable to use a franchisor or the like as a drive torque source and adopt an electromechanical push button operating mechanism. However, the use of a large number of franchisors not only increases cost, but also has many disadvantages in terms of reliability, power consumption, space factor, etc.

を提案せんとするものである。Therefore, in view of the above-mentioned points, the present invention selectively changes the rotation stop position of a rotating disk for mounting a tape in order to electrically switch the tape transport mode based on the opening/closing operation of a switch.
The present invention proposes a tape transport mechanism that switches to different tape transport modes by activating a common drive at each stop position.

れている。The drawing number 1 shows a guide cylinder that pushes a rotating head (not shown), 2 shows a rotating disk for loading the tape in the cylinder 1, and 3 shows a pull-out lever that pulls out the tape stretched in the cassette. . Therefore, when the tape is loaded, as the rotary disk 2 rotates, the engaging pin 3c of the guide lever 3b, which is supported by the guide lever 3b, is biased against the first lever 3a at the tip of the pull-out lever 3, and the engaging pin 3c of the guide lever 3b is pivoted against the rotary disk. 2 engages with the recessed notch 2a on the outer periphery. Therefore, the pull-out pin 3d at the tip of the pull-out lever 3, which rotates together with the rotating disk 2, pulls out the tape stretched in a cassette (not shown) to the outside of the cassette, and is formed by the pull-out pin 3d and the cassette opening. The rotating disk 2 is placed in the table loop to be
Leading guide pin 2b and pinch roller 2c arranged above
to invade. Next, the pull-out lever 3 further rotates after the leading guide pin 2b and the pinch roller 2c enter, and the engaging pin 3c of the guide lever 3b and the recessed notch 2a
The engagement is released by a locking member 4 fixed to the outer periphery of the rotary disk 2, and only the rotation of the pull-out lever 3 is stopped. Further, while rotating, the rotating disk, along with the guide pins 2d, 2d, etc. that enter the loop one after another, keeps the tape on the outbound path and the tape on the return path in a non-contact state, and winds the tape around the cylinder 1 and fixes it. It is brought into contact with the guides 5, 5 and the control head 6. The rotation of the rotary disk 2 stops when the pinch roller 2c reaches the position where the pinch roller 2c is in contact with the capstan 7, but before stopping, the tension lever 8 is moved between the supply reel (not shown) and the guide cylinder 1. Since the tension detection pin 8a (partially shown only in FIG. 2) moves in the direction of winding the tape around the guide cylinder 1, the tape also comes into contact with the erasing head 9. Therefore, the tape includes a tension detection pin 8a1, an erasing head 9, a guide cylinder 1, a control head 6, and a capstan 7.
, the leading guide pin 2b1, the pinch roller 2C1, the guide pin 2d, . . . , and the pull-out pin 3d. An embodiment in which the present invention is applied to the above-mentioned VTR will be described in detail below with reference to FIGS. 1 to 4. First, reference numeral 10 is a common driving source for each mode, and a plunger is driven after the rotation direction of a sliding lever 13 (to be described later) is determined. Reference numeral 11 is a first fixed shaft that is driven by the pulling operation of the plunger 10. A rotary lever 11a rotates around a second fixed shaft 12a, a mode detection member 12 is biased to rotate counterclockwise around a second fixed shaft 12a by a second spring 12b, and 13 a mode detection member 13 that rotates around a second fixed shaft 12a. A sliding lever whose sliding direction is regulated by the planting pin 12c and the third fixed shaft 13a, and 14 are the first and second rotating members 15 and 16 which constitute the first support body, and the second rotation member which constitutes the second support body. 3. It is a fourth fixed shaft that pivotally supports the fourth rotating members 17 and 18 in a skewer shape. Both take-up reel stands 22a, 22 are in common contact with the reel stand 22b.
A connecting pulley 9 (rotation transmitting means) that prevents sliding due to the slip mechanism interposed between the second rotating member 16
, a fast forwarding pin 16a is pressed by the sliding lever 13 during fast forwarding, and a rewinding pin 17a is pressed by the sliding lever 13 during rewinding. 4 Rotating member 18 has a rotation drive pulley 20 and a belt 21
An idler 23 (rotation transmitting means) connected to the lower take-up reel stand 22b during normal operation is provided.

At the spring 24, the third rotating member 17 and the fourth rotating member 18
are elastically connected by the fourth spring 25, so that the pressing force of the sliding lever 13 is elastically transmitted to the connecting pulley 9 or the idler 23. Furthermore, figure number 13
b, 16b, and 17b indicate springs for returning the sliding lever 13, the second rotating member 16, and the third rotating member 17, respectively. The operation of this embodiment in each mode will be described below. When stopped (as shown in Figure 1), the pull-out pin 3d of the pull-out lever 3 is located at the opening/mouth portion of the cassette, and the engagement pin 3c at the tip of the guide lever 3b is in contact with the outer periphery of the rotating disk 2, so that the mode is detected. The member 12 is in a state where it has rotated slightly clockwise against the bias of the second spring 12b.

a, but the plunger 10 does not operate. During performance (as shown in FIG. 2), the engaging pin 3c of the guide lever 3b moves with the tape loading operation and is held by the locking member 4.

れる。Therefore, the mode detection member 12 rotates counterclockwise from the stopped state and comes into contact with the outer periphery of the rotating disk 2.
Therefore, the direction of the sliding lever 13 is deviated from the rewinding pin 17a and the fast forwarding pin 16a. Thereafter, in this state, the plunger 10 operates with a delay, and the rotating lever 1
1 elastically presses the pinch roller 2c against the capstan 7. In this state, the idler 23 drives the lower take-up reel stand 22b, and the rotation of the lower take-up reel stand 22b is transmitted to the upper take-up reel stand 22a via the slip mechanism, and the tape is transferred to the take-up reel stand 22a. It is wound up.

アイドラー23は供給リール台に圧接される。Therefore, the mode detection member 12 rotates further clockwise than the state at rest, and moves the sliding lever 13 toward the fast-forwarding pin 1.
It rotates in the direction of 6a. Thereafter, in this state, the plunger 10 operates with a delay, so that the connection pulley 19 is elastically pressed against the upper and lower take-up reel stands 22a and 22b. Therefore, the rotation of the idler 23 is caused by the rotation of the lower take-up reel stand 22b1 and the connection pulley 1.
9. The signal is transmitted to the upper take-up reel stand 22a, and the upper take-up reel stand 22a is driven at high speed. During rewinding (as shown in FIG. 4) the rotating disk 2 and the sliding lever 13
is in the same state as when it is stopped, but since the plunger 10 operates with a delay in this state, the idler 23 is pressed against the supply reel stand.

However, in place of the above-mentioned means, the present invention provides a plurality of step-like steps on the rotary disk, and uses the steps to connect the remote sensing member intermittently. It is also possible to rotate.
