Further, on the second mounting surface 52 of the sub-board 5 mentioned above, there is a
The lth position regulation stage 70 is attached with reference to 2.

This means 70 (surface portions 521 and 52 as the mounting surface 52)

A surface inclined by approximately lO0 (virtual surface S-53 mentioned above)
It is designed so that it can be rotated in a parallel direction.

In this case, the outer diameter φ'2 of the rotating ring 93 (1) is selected to be smaller than the distance between the left and right side surfaces 3o and 31 of the magazine M mentioned above, and the entire magazine M is mounted on the mounting section 4. Extended virtual ffis of the left side 30 (the right side in Figure 1)
A and an extended imaginary surface SB of the right side surface 31 (the left side surface in FIG. 1) or an extended imaginary surface SB' facing this imaginary surface SH with a slight distance from the outside,
Further, the rotating ring 93 is arranged as far forward as possible toward the mounting section 4 so that a portion thereof is located below the magazine M mounted on the mounting section 4 when viewed from the top.

Further, the rotating ring 93 has, for example, approximately two
Stop notches 95 and 96 are provided with an angular spacing of 900 mm, and on the main surface 2 of the main board 1, for example, at a position below the magazine M mounted on the mounting section 4, a rotation ring 93 is formed. Engagement piece 9 pressed toward the outer peripheral surface (means not shown)
7 is arranged, and the rotary ring 93 moves from the l-th rotation position where the engagement piece 97 engages in the notch 95 to the notch 96 by approximately 2900 rotations clockwise when viewed from above. The second rotational position in which the engagement piece 97 engages is taken within the inner part.

Further, the rotary ring 93 has a binder roller so as to be positioned in the empty space 39 in the case 11 of the magazine M when the magazine M is attached to the mounting portion 4 at the first rotation position. 98 is placed.

In this case, the shaft 99 of the Vinci roller 98 is a rotating arm 101 that extends counterclockwise along the extension direction of the ring 93 when viewed from the shaft 100 that is pivotally connected to a shaft 100 that is mounted on the rotating ring 93.
The rotating arm 101 is attached to the free end of the ring 9.
This arm 101 is attached to the main board 1 (the attachment means is not shown) when the rotating ring 93 is in the l-th rotating position on the spring 102 mounted between the cam plate 103 and the cam plate 103. The ring 93 is in pressure contact with the cam 104 from the front side when viewed from the top.
When arm 1 is at a rotational position other than the l-th rotational position,
01 is rotated counterclockwise so as to collide with the engagement piece 105 attached to the ring 93.

In this case, the cam surface 104Lt of the cam plate 103 is a surface that recedes backward as it goes counterclockwise along the extension direction of the ring 93. Therefore, when the ring 93 is at the l-th rotational position, the Vinci roller 98 is flat. When the ring 93 is rotated clockwise from this point, the Vinch roller 98 moves to the rear left when viewed from the top. 98 is designed so that it can be more easily led out of the space 39 than the space 39.

In addition, the pinch roller 98 is such that the arm 101 is connected to the engagement piece 105.
The outer diameter is selected so that a part of the outer circumferential surface of the ring 93 can sufficiently protrude from the inner circumferential surface of the ring 93 when the ring 93 collides with the ring 93.

On the arm 101 to which the pinch roller 98 is attached,
A tape pull-out/guide pin 106 is installed at a predetermined distance clockwise from the position of the vinyl roller 98 along the extension direction of the ring 93.

Therefore, the Vinci roller 98 is arranged at a position behind the pin 106 in the rotation direction when the rotation ring 93 rotates from the first rotation position to the second rotation position. .

In this case, when the ring 93 is in the first rotational position, the pin 106 is positioned in the empty space 39 of the magazine M mounted on the mounting section 4 together with the Vinci roller 98, which will become clear with the operation described later. It has a shape.

Further, the ring 93 is placed at a position slightly counterclockwise relative to the position of the Vinci roller 98, that is, when the rotating ring 93 rotates from the first rotating position to the second rotating position. The rods 1 of the tape guide mechanisms 111-1 to 111-3, which will be described later, of the ring 93 are positioned behind the pinch roller 98 in the moving direction.
An engagement hole 108 is provided at the free end of the ring 93 to which an engagement roller 118 engages, and is located at a predetermined distance counterclockwise in the extending direction of the ring 93 when viewed from the Vinci roller 98. Tape guide pins 74 and 75, 86 and 8 mentioned above
A tape guide pin 109 having a pair of flanges 76 and 77 similar to 4 is installed extending perpendicularly to the plane formed by the ring 93.

Further, the rotating ring 93 is rotated by a driving wheel 110 (its mounting means and driving mechanism are not shown) mounted on the main surface 2 of the main board 1 and rotates against the inner circumferential surface of the ring 93 to form a so-called rim drive. It is configured such that it can be rotated between the first and second rotational positions as described above in the formula.

Further, the tape mounting means 81 has tape guide mechanisms 111-1, 1112, and 111-3 provided corresponding to the surface portions 53-c1 to 53-c3 as other parts of the mounting surface 53.

This tape guide mechanism 111-1 has a U-shaped angle 112.
The bottom plate portion 113 is in contact with the surface portion 53-CI and is attached to the surface portion 53-CI.

In this case, the angle 112 is
The relative position with respect to the ring 93 is determined such that a line connecting the rings 115 and 115 passes through the virtual axis of the ring 93 or its vicinity.

Also, the mechanism 111-1 has two opposing plates 11 of the angle 112.
It has a rotating shaft 116 that can be rotated to extend the bridge between 4 and 115, and a tape guide pin 117 that can be extended from this.

In this case, there is a θ3 between the rotating shaft 116 and the pin 117 within the range of 1-loC±l5° in terms of virtual extension including the rotating shaft 116, and the shaft 116 is on the outer circumferential surface side of the ring 93 in the plan view. The pin 117 extends from the outside to the inside of the inner circumferential surface side, passing under the ring 93 and extending toward the rotating magnetic head device 60 side as it approaches the virtual plane formed by the ring 93 as it approaches the inside. is always arranged in the space between the inner circumferential surface of the ring 93 and the tape guide surface 67 of the rotary magnetic head device 60 when viewed in a plan view.

Further, the rotating shaft 116 formed by extending the pin 117 is provided with an engaging roller 118 as an engaging element at the free end of the rod 1.
19 is installed.

In this case, the virtual plane including the rotation axis 116 and the rod 119 is the axis 11
The roller 118 is a virtual surface different from the above-mentioned virtual surface including the pin 117 and the roller 118, and although the roller 118 normally exists on the lower surface side of the ring 93, the above-mentioned engagement hole 108 formed in the ring 93 is located in the engagement hole 108 when the roller 111 is in the position of the mechanism 1111, and thus the roller 118
The rod 1 is neutral when it is exactly in the engaging hole 108.
Spring 120 and 1 that can be inserted between 19 and angle 112
21, the shafts 116 are rotated in the clockwise and counterclockwise directions when viewed from their outer end surfaces. Therefore, if the engagement holes 108 are in the retracted position due to the position of the mechanism 1111, the rollers 118 are activated. 120 and 121 are opposed to the lower surface of the ring 93 against the force of force.

Then, while the roller 118 is in contact with the lower surface of the ring 93 due to the force of the spring 120, the pin 117
Therefore, the pin 117 maintains an upright position extending in a direction substantially perpendicular to the above-mentioned virtual plane S-53, and in this down position, the pin 117 touches the tape guide surface 6 of the rotating magnetic head device 60.
7 and the free end of the pin 117 is located at a position where it can be sufficiently raised above the virtual surface formed by the ring 93, and the roller 118
is in contact with the lower surface of the ring 93 due to the force of the spring 121, so that the free end of the pin 117 is in a position close to the imaginary shape formed by the ring 93, that is, the so-called pin 117 is in a fallen state. is being done.

The tape guide mechanisms 111-2 and 111-3 have exactly the same configuration as the tape guide mechanism 111-1 described above, and therefore the mechanism 111-2 and 111-3 have the same configuration as the tape guide mechanism 111-1 described above.
The same reference numerals are given to the parts corresponding to 1, and detailed explanations are given (1) Although this is omitted, the bottom plate part 113 of the angle 112 corresponds to the surface parts 53-c2 and 53-c of the third mounting surface 53. ．．
3 are installed on each.

The tape drive means 82 mounted on the third mounting surface 53 of the sub-board 5 also has a capstan 131 connected to suitable rotation means, which is connected to the surface portion 5:3- as another part of the surface 53. It is pivoted on d1 in a relationship that extends orthogonally to this plane (
The pivot means are not shown).

On the other hand, a brake drum 141 is attached to a position below the attachment position of the reel stand 41 of the supply reel shaft 37 mentioned above, and a support column 142 is installed at a position slightly to the left behind the drum 141 on the main surface 2 of the main board 1. Further, a shaft 143 is installed at a position slightly to the right behind the drum 141 on the main surface 2,
A tension arm 144 is pivotally connected to the shaft 143, and a brake shoe 146 is extended between one free end 145 of the tension arm 144 and the support 142, and extends around the brake drum 141. , and extend it downward to the side opposite to the free end 145 side, and insert pin 1.
47 is planted, and a tape guide pin 149 that can be extended upward is also planted on a free end 148 of the arm 144 on the side opposite to the free end 145 side that sandwiches the shaft 143.

is erected, and an arm 151 is rotatably pivotally attached to this shaft 150, and on the other hand, this arm 151 is rotated clockwise in plan view by a spring 152 that can be inserted between this arm 151 and the main board 1. The rotation of the arm 151 is stopped by a stop piece 153 planted on the substrate 1.

Further, the tension arm 144 is rotated clockwise in plan view by the spring 154 inserted between the tension arm 144 and the base plate 1, so that the pin 147 is rotated in the one end 15 of the arm 151.
It is designed so that it collides with 5.

However, in this case, the force exerted by the spring 154 is weaker than that of the spring 152 described above, so the arm 151 must be kept in a position where it collides with the stop piece 153, and the rotation of the arm 144 is caused by its pin. 147 collides with the end 155 of the arm 151 and is stopped.

Therefore, the arm 151 is in contact with the stop piece 153, and the arm 151 is in contact with the stop piece 153.
In the down position where the pin 147 of the arm 144 collides with the end 155 of the arm 151, the pin 149 is attached to the magazine mounting part 4.
Case body 1 of the magazine M in the state where it is attached

On the other hand, on the lower surface of the above-mentioned rotating ring 93, this ring 93 is located at the lth position.
The shaft 1 of the arm 151 mentioned above is moved from the position immediately before reaching the second rotation position to the second rotation position.
A pin 157 is installed to sandwich the arm 150 and engage with the end 156 opposite to the end 155 to rotate the arm 151 in a counterclockwise direction when viewed from a plan view against the spring 152. When the ring 93 is in the second rotational position, the arm 151 assumes its maximum counterclockwise rotation position, and in response, the arm 144 assumes its maximum clockwise rotation position and rotates the brake shoe 146. The pressure applied to the brake drum 141 is maximized.

Although the outline of the structure of an example of the present invention has been clarified above,
Next, to further describe the operation, the magazine M described above in FIGS. 3A, B, and C is mounted in the magazine mounting section 4 described above as described above.

Before the magazine M is mounted on the mounting section 4, the notch 95 of the rotating ring 93 of the tape mounting means 81 is connected to the engagement piece 97.
Therefore, when the magazine M is mounted on the mounting portion 4 and placed on the ring 93, the Vinci roller 98 and tape drawer/guide located on the ring 93 The pin 106 & 1 magazine M is placed in the cavity 39 of the case body 11 from below through the notch 36.

In this case, the pin 106 and the pinch roller 98 are provided on the rotating arm 101 which is bitten by the spring 102, and since this arm 101 is engaged with the cam surface 104 of the cam 103, the pin 106 and the pinch roller 98 %, the vinyl roller 98 is located on the back side of the tape 27 inside the case body 11 of the magazine M, in a perpendicular position.

In this down position, the engagement piece 97 is disengaged from the notch 95, and the drive wheel 110 is driven, thereby causing the rotation ring 93 to rotate clockwise as viewed in FIG.

When the rotating ring 93 is rotated in this manner and the notch 96 thereof is rotated to a position facing the engaging piece 97, the engaging piece 9
7 is pressed against the outer circumferential surface of the ring 93, and the ring 93 assumes a second rotational position in which the engagement piece 97 engages in the notch 96, and at this time the drive of the drive wheel 110 is released.

When the rotation ring 93 rotates from the l-th rotation position, the pin 106 and the pinch roller 98 move to the right rear, so that the tape 27 that can be stretched between the pins 24 and 25 in the magazine M is The tape 27 is pulled out to the right rear by the pin 106 and the pinch roller 98, and then forms a loop that extends from the pin 24 of the magazine M to the pinch roller 98 pin 106 to the pin 25, and then the tape 27 is pulled out to the right rear from the reel 18 side. Then, pin 24 - Vinci roller 98 - Pin 1
06-The tape 27 is pulled out to the right while forming a loop surrounding the pin 26.

In this way, when the tape 27 is pulled out and the loop length of the tape 27 is gradually increased, the ring 93 rotates and the engagement hole 108 attached thereto comes to the position of the tape guide mechanism 1111, and this mechanism 111- Roller 11 attached to rod 119 of No. 1
8 has been in contact with the lower surface of the ring 93 until now, the hole 108
As a result, the rod 119 and therefore the rotation shaft 116 rotate clockwise when viewed from the outer end surface side, and the ring 93 further rotates and the roller 118 moves into the hole 10.
8 and comes into contact with the lower surface of the ring 93, the tape guide pin 117 attached to the rotating shaft 116 stands up.

In this case, the pin 117 is raised up by the pin 24 of the magazine M.
- Binch roller 98 - Pin 106 - This is done inside the roof 0 of the tape 027, which is widened by the pinch roller 98 that covers the pin 26, so the tape 27 does not get in the way.

In this way, when the pin 117 of the mechanism 111-1 stands up and the ring 93 subsequently rotates, the tape 27 forms a loop that covers the pin 24 of the magazine M, the vinyl roller 98, the pin 106, the pin 117, and the pin 26. Then, if the hole 108 of the ring 93 passes the position of the next tape guide mechanism 111-2, this mechanism 1 is pulled out in the same manner as described above.
The pin 117 of 11-2 stands up, and the tape 27 is connected to the pin 24 of the magazine M, the pinch roller 98, the pin 106, and the mechanism 1.
Pin 117 of 11-2 - Pin 117 of mechanism 111-1
A loop is formed around the pin 26 of the magazine M, and if the hole 108 of the ring 93 passes the position of the next tape guide mechanism 111-3, this mechanism 1113 is pulled out in the same manner as described above. pin 117 stands up and tape 2
7 is pin 24 of magazine M - Vinci roller 98 - pin 1
Pin 1 of 06 mechanism 111-3, 111-2 and 111-1
17 - forms a loop around pin 26 and is pulled out even further.

When the ring 93 rotates while pulling out the tape 027 and reaches the second rotation position where the notch 96 engages with the engagement piece 97, the ring 93 is rotated from just before reaching the second rotation position. The arm 151 associated with the tension arm 144 is rotated counterclockwise in FIG.
is rotated clockwise as seen in FIG. 1 by the force of the spring 154, and the tape guiding hinge 149 attached to this arm 144 moves rearward to the right, thereby causing the tape 27 to move between the reel 17 and the pin 149. l-th position regulating pin 75 and 7
4-Second position regulating pins 86 and 87-Vinch roller 9
8-pin 106-bin 109-mechanism 111-3, 11L
-2 and 1111 pin 117-pin 26-reel 18 loop is formed.

The tape loop in this case is the rotating magnetic head device 6.
Therefore, the tape 27 also covers the tape guide surface 67 of the rotary magnetic head device 60 when viewed in FIG.
The tape 27 is mounted on the tape guide surface 67 with the tape 27 being in contact with the tape 27 over a range slightly more than 1,800 degrees when viewed from the surface 67 extending from the front left position to the rear right position. Ru.

In this way, when the tape 27 is hung on the tape guide surface 67 in the down position, the upper and lower edges of the tape 27 (1, between the reel 17 in the magazine M and the pin 149 of the tension arm 144; Between the pins 74, there is a substantially parallel relationship with the main body 2 of the main board 1, and between the position regulating pin 74 and the rotating surfaces of the rotating magnetic heads 65 and 66 on the working area 67 of the rotating magnetic head device 60. Between the position farthest from the main surface 2 on the top (1) and the position opposite to the main surface 2 (this is referred to as Q1), (1 approximately parallel to the main surface 2 of the main substrate 1 or at the latter position) The relationship between the position Q1 and the position regulating pin 86 is such that the relationship approaches the main surface 2 as it approaches the main surface 2, and the relationship approaches the main surface 2 as it approaches the latter pin 86. between pin 86 and pin 106 is approximately the same as the inclination between position Q1 and pin 86, and between pins 106 and 109 (1 pin 8
6 and 106, and the pin 109 and mechanism 1
11-3 pin 117 and mechanism 111. -3 and 111-
between the two pins 117 (the first mechanism 111-2 side is inclined with respect to the main surface 2 in such a manner that it moves away from the main surface 2,
Between the pins 117 of the mechanisms 111-2 and 111-1, the closer you get to the mechanism 111-1, the further away from the main surface 2 there is a relationship that is approximately parallel to the force pouring surface, which is inclined to the main surface. The pin 117 and pin 26 of the mechanism 111-1 are approximately parallel to the main surface 2.

The above-mentioned state in which the tape 27 is mounted on the tape guide surface 67 (i) can be achieved very easily due to the presence of the pin 106 that is installed on the Vinci roller arm 101 provided on the fli93.

The reason is that the outer peripheral surface of the pin 106 has a curved surface 107,
The curved surface 107 moves the tape 2 while the bin 106 moves from the position in the empty space 39 of the magazine M to the position farthest from the main surface 2 or near the position.
A component force is applied to the tape 27 to keep the upper edge of the pin 1 slightly closer to the main surface 2 side or approximately parallel to the main surface 2.
Comparison for bringing the upper edge of the tape 27 closer to the main surface 2 side while moving to the position where the tape 06 is farthest from the main surface 2 or the closest position to the main surface 2, or the vicinity thereof. These are 7) which apply a force to the tape 27.

When the tape 27 is mounted on the tape guide surface 67 as described above, it rolls into contact with the capsun 131 by pinching the vinyl rollers 98G-3-j--27.

For this purpose, tape 27 (1 tape from the reel 17 side of 1 magazine M)
8 side at a constant speed.

In this case, the tension arm 144 receives the tension of the tape 27 through a pin 149 attached thereto, and rotates to keep the tension of the tape 27 substantially constant without being restricted by the arm 151.

However, the rotation range is maintained within a range in which the tape 27 does not stop covering the pin 75.

Therefore, the tape 27 (1) is transferred while being brought into contact with the erasing head with a predetermined contact pressure.

On the other hand, as the tension arm 144 rotates, the contact pressure of the brake shoe 146 against the brake drum 141 changes, and the tension of the tape 27 is quickly returned to a predetermined range.

In this way, the tape 27 is transported at a constant speed while keeping the tension within a predetermined range and touching the tape guiding surface 67 of the rotating magnetic head device 60. During this time, an erasing signal is not sent to the erasing magnetic head 78. When a video signal is given to the rotating magnetic heads 65 and 66 and a control signal is given to the control magnetic head 83, the video signal is recorded on the magnetic tape 27 forming an oblique magnetization locus, and the control signal is also given to the magnetic tape 27. is the bottom of this tape 27 (
1, a magnetization trajectory parallel to the upper edge is formed and recorded.

If the magnetic tape 27 is capable of recording such video signals and control signals, these signals are reproduced by the magnetic heads 65, 67, and 83 while the erasing magnetic head 78 is inactive.

Recording onto or reproducing from the magnetic tape 27 is completed by stopping the rotation of the capstan 131 and stopping the transport of the tape 27.

After recording on or reproducing from the magnetic tape 27 is completed, the rear engaging piece 97 is disengaged from the notch 96 of the ring 93, and the rear drive wheel 110 is driven in the opposite direction to the above-mentioned case, and the reel shaft is rotated. 38 is driven weakly, the ring 93 rotates counterclockwise from the second rotation position in the counterclockwise direction as seen in FIG. Mechanisms 1111 to 1113 and the like perform operations that are completely opposite to the above-mentioned case in which the mechanism rotates to the second rotation position.

However, in this case, the arm 101 of the winch roller 98 engages with the cam 104 of the cam plate 103, so the winch roller 9
8 is in a more forward position than in FIG.
The pinch roller 98 is smoothly brought to the rear side of the magnetic tape 27 without being disturbed by the pinch roller 98%.

In this way, the same state as when the magazine M is initially mounted on the mounting section 4 can be obtained.

Therefore, from this state, the magazine M is placed in a down position from which it can be taken out from the mounting section 4.
