Abstract

PURPOSE:To omit the requirement for moving a chassis by bringing a cassette guide into contact with the rear surface of a tape cassette at a position before a reel and a reel stage are engaged, and performing the opening of a lid and the releasing of a reel lock. CONSTITUTION:The front side of a cassette holder 41 is pushed down to the side of a chassis 46 against the energizing force of a torsion spring 53. Then, the cassette holder 41 is turned with a supporting pin 87 as a supporting point, and a slant state is obtained. When the holder is further pushed down, a lid opening lever 49 is turned in the clockwise direction relatively with respect to the cassette holder 41 because a guide pin 52 is freely coupled with a guide groove 48. Thus, a lid 32 is opened. A reel unlocking member 56 is also turned, and the reel is unlocked. A magnetic tape is pulled out during the period wherein the tape cassette is guided from that position to a position where the reel and a reel stage are engaged with the cassette holder. The tape is wound around a cylinder 24. Therefore, it is not necessary to move the chassis 46 for bringing the cylinder 24 and the tape cassette 31 close together.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape cassette loading mechanism in a magnetic recording and reproducing apparatus that records and reproduces signals by winding a magnetic tape pulled out from a tape cassette around a cylinder.

2. Description of the Related Art In recent years, there has been a demand for miniaturization of helical scan type video cassette recorders (hereinafter abbreviated as vCR), and in order to meet this demand, efforts have been made to miniaturize each part. Among them, reducing the thickness and changing the arrangement of parts that affect the thickness.

One of the items that should be especially considered when trying to downsize a VCR is how thin the whole can be made by replacing it with something else. As one means of reducing the thickness, it is important to devise a tape cassette mounting mechanism.

The conventional VCH tape cassette mounting mechanism will be described below. In addition, in the following description, if similar members are arranged on the left and right sides, the description will be limited to only one side.

FIG. 5 is a perspective view of a conventional VCH at a cassette attachment/detachment position. In FIG. 5, 1 is a cassette holder;
It is integrally constituted by a top plate 2, a side plate 3 bent on both sides thereof, a bottom plate 4 formed by bending the side plate 3 inward, and a stopper 5 bent upward in front of the bottom plate 4. The cassette holder 1 has a first link 6 and a second link 11.
It is supported by the sub-chassis 18 by. One end of the first link 8 is connected to the subchassis 1 by the fulcrum pin 7.
A guide pin 8 protrudes from the other end and loosely fits into a guide groove 9 provided in the side plate 3. Contrary to the first link 6, the second link 11 has a guide pin 13 at one end.
A guide groove 14 provided in the sub-chassis 18 and protruding from the guide groove 14
The other end is pivotally connected to the side plate 3 by a fulcrum pin 12. Further, the first link 6 and the second link 11 are connected at the center by a connecting pin 16, which allows the cassette holder 1 to be moved close to and away from the sub-chassis 18 while remaining parallel to the sub-chassis 18. The spring hook provided on the first link 6 is biased in the direction of separating the cassette holder 1 from the sub-chassis 18 by a tension spring 17 stretched between the hole 10 and the spring hook provided on the side plate 3 and the pin 15. At the cassette attachment/detachment position, the guide pin 8 comes into contact with the right end of the guide groove 9 and is locked therein. The sub-chassis 18 includes a lid release pin 19 that contacts the lid 32 of the tape cassette 31 to open the lid 32 as shown in FIG. 7, and releases the reel lock by being inserted into the reel lock release hole 33 of the tape cassette 31. The tape cassette 31 is released by contacting the reel lock release pin 20, the reel stand 21 that engages with the reel 34 of the tape cassette 31, and the rear surface 85 of the tape cassette 31.

As a result, the cylinder 24 enters the bottom opening 36 of the tape cassette 31 shown in FIG. 7, and the tape cassette 31 and the cylinder 24 come close to each other. Also,
At the same time as the sub-chassis 18 slides, the tape is pulled out by a tape pull-out post (not shown) inserted into the bottom opening 36 of the tape cassette 31 at the temporary attachment position, and the pulled-out magnetic tape 37 is wound around the cylinder 24. Can be attached. Then, signals are recorded and reproduced on the magnetic tape 37 wound around the cylinder 24.

Problems to be Solved by the Invention However, in the above conventional configuration, in order to bring the cylinder and tape cassette closer together, after opening the lid of the tape cassette, the sub-chassis on which the tape cassette is temporarily attached is slid against the main chassis. There is. Therefore, two chassis exist below the tape cassette.

For this reason, even if the cassette could be made smaller in the front-rear direction, the thickness would inevitably increase compared to the case where only one chassis was required, and there was a problem in that the VCR could not be made smaller. .

The present invention solves the above-mentioned conventional problems, and the VCR can be made thinner because only one chassis is required, and furthermore, the cylinder and tape cassette can be placed close to each other, making it possible to reduce the size of the VCR.
The purpose is to provide To do this, before the reel and reel stand engage, open the lid and release the reel lock in the cassette holder to make it possible to pull out the magnetic tape, and then use the cassette holder to open the tape cassette while winding the magnetic tape around the cylinder. The first purpose of this operation is to guide and hold the tape cassette in a fixed position within the cassette holder at a position before the reel and reel stand engage. do.

FIG. 2 is a perspective view of the lid opening mechanism and the reel lock release mechanism. FIG. 2 shows the relationship at the cassette mounting position, and shows only the main parts extracted from the whole. 4
Reference numeral 9 denotes a lid opening lever, which is pivoted to a support pin 50 provided on the side plate 43, and is connected to the tape cassette 3 shown in FIG.
A lid opening pin 51 that opens the lid when rotated clockwise from the position shown in FIG. 1 to the position shown in FIG. 2 while contacting the lid 32 of FIG.

Also, when the cassette holder 41 reciprocates between the cassette attachment/detachment position and the cassette attachment position, the support side plate 4 shown in FIG.
A guide pin 52 is protrudingly provided to loosely fit into a guide groove 48 provided at 7, support the cassette holder 41 on the front side, and guide the cassette holder 41 on the front side. Then, the torsion spring 53 fitted onto the support pin 50 releases the lid release pin 51 from the lid 32 and rotates the lid release lever 49 so as to keep the entire cassette holder 41 in the cassette attachment/detachment position separated from the chassis 46 shown in FIG. It is biased to rotate clockwise. Reference numeral 56 denotes a reel lock release member, which is pivoted to a support pin 57 provided on the side plate 43, and its central portion is bent and rotated counterclockwise from the position shown in FIG. 1 to the position shown in FIG. A reel lock release piece 5 is inserted into the reel lock release hole 33 of the tape cassette 31 shown in FIG. 7 to release the reel lock when
It is 8. Furthermore, the central part of the reel lock release member 56 is bent in a different direction from the reel lock release piece 58, and when rotated, the cassette contacts the rear surface 35 of the tape cassette 31 to regulate the position of the tape cassette 31. A guide 59 is provided. The lid release lever 49 and the reel lock release member 56 are connected by a connecting pin 54 provided on the lid release lever 49 loosely fitting into a long hole θO provided on the reel lock release member 56. When the reel lock release member 56 rotates, the reel lock release member 56 also rotates in conjunction with the rotation. 61 is a locking member, and a support pin 62 (
1), and is biased clockwise in the figure by a tension spring 66 stretched between the hole 63 of the spring hook and the pin 65. Therefore, when the lid release lever 49 is in the position shown in FIG. When the lid opening lever 49 is rotated clockwise from the position shown in FIG. 1 to the position shown in FIG. The locking member 61 rotates counterclockwise once when the locking member 61 comes into contact with the locking pin 55, and after passing the locking pin 55, rotates clockwise to lock the locking pin 55. As a result, the lid release lever 49 and the connecting pin 5 are connected to the lid release lever 49.
The position of the reel lock release member 56 connected to the cassette holder 41 via the reel lock release member 56 is locked.

FIG. 3 is a perspective view of the tape winding mechanism. FIG. 3 shows the relationship at the cassette mounting position, and shows only the main parts extracted from the whole. Reference numeral 71 denotes a tape winding slider, which has an L-shape, and slide grooves 72 and 73 provided on the horizontal portion engage holding pins 74 and 75 provided on the bottom plate 44, respectively, so that the cassette can be removed. It is held by the holder 41 and is slidable in the front and rear directions. A leaf spring 77 is integrally provided at the center of the tape winding slider 71 by means such as welding, and a friction member 78 made of rubber or the like is fixed to the tip of the leaf spring 77 to generate friction when the tape winding slider 71 slides. The member 78 comes into contact with the reel 34 seen from the bottom of the tape cassette 31 shown in FIG. 7, and the reel 34 is rotated in the tape winding direction due to frictional force, thereby winding the magnetic tape 37. A winding drive lever 79 is pivoted to a support pin 80 provided on the side plate 43, and when a drive pin 81 protruding from one end engages with a notch 76 of the tape winding slider 71, the winding is started. The tape winding slider 71 slides in conjunction with the rotation of the driven bar 79. Reference numeral 83 denotes an arm, and a hole 84 at the end thereof is press-fitted into a synchronizing shaft 85 supported by the support side plate 47 shown in FIG. 1, so that the left and right arms 83 rotate in the same phase. In addition, the center part of the arm 83 is connected to the side plate 4.
The cassette holder 41 is pivoted on a support pin 87 provided on a support plate 86 fixed to the winding drive lever 7 and supports the cassette holder 41 on the rear side.
9, the take-up drive lever 79 is rotated in accordance with the rotation of the arm 83. The relationship between the rotation of the arm 83 and the rotation of the take-up drive lever 79 will be explained. FIG. 3 shows the cassette in the mounting position, where the drive pin 88 is disengaged from the take-up drive lever 79. In this state, a torsion spring 82 fitted around the support pin 8 degrees urges the take-up drive lever 79 to rotate clockwise so that the take-up drive lever 79 does not rotate counterclockwise. Furthermore, if the take-up drive lever 79 is rotated further in the clockwise direction, the right end of the slide groove 72 will be blocked by the holding pin 74.
It is regulated by coming into contact with. Further, in this state, the friction member 78 is in a position where it does not interfere with the engagement between the reel 34 and the reel stand 21. When moving from this mounting position to a temporary mounting position, which will be described later, the arm 83 rotates clockwise about the support pin 87 relative to the cassette bolt 41. At first, the drive pin 88 only moves the circular arc portion 90 concentric with the support pin 87 of the take-up drive lever 79 and does not rotate the take-up drive lever 78.
After the engagement with the reel stand 21 is disengaged), rotate the take-up drive lever 79 until the arcuate portion 89 is concentric with the support pin 87, and even after the arcuate portion 89 is concentric with the support pin 87, the arm 83 rotates further, and the drive pin 88 reaches the circular arc portion 89.
Move to the end of and stop.

During this movement from the mounting position to the temporary mounting position, the tape winding slider 71 slides in conjunction with the winding drive lever 79 to wind the tape. When moving from the temporary attachment position to the attachment/detachment position shown in FIG.
8 only moves the circular arc portion 89 concentric with the support pin 87 of the take-up drive lever 79, and the take-up drive lever 79 does not rotate.

The reverse movement from the attachment/detachment position to the temporary attachment position is similar, and the arm 83 rotates clockwise, but the take-up drive lever 79 does not rotate. Furthermore, when moving from the temporary mounting position to the mounting position shown in FIG. 3, the arm 83 rotates counterclockwise relative to the cassette holder 41. In this rotation, the drive pin 88 initially only moves the arc portion 89 and does not rotate the winding drive lever 79, but from the middle of the rotation, the drive pin 88 only moves the arc portion 89.
The take-up drive lever 79 is rotated until it becomes concentric with the support pin 87. Then, even after the arc portion 90 becomes concentric with the support pin 87, the arm 83 continues to rotate, and the drive pin 88
moves along the arc portion 90 and finally stops at a position away from the arc portion 90.

The operation of the VCR configured as described above will be explained below. FIG. 4 shows V in the embodiment of the present invention.
It is a side view explaining the cassette mounting operation by CR.

First, at the cassette attachment/detachment position shown in FIG. 4(a), the lid opening pin 51. Although the reel lock release piece 58 and the cassette guide 59 are located at a position that does not hinder the attachment and detachment of the cassette,
At this position, the tape cassette 31 is inserted into the cassette holder 41 until it contacts the stopper 45.

Next, the front side of the cassette holder 41 is pushed down toward the chassis 46 by hand against the biasing force of the torsion spring 53. Due to the push-down operation, the cassette holder 41 rotates about the support pin 87 as a fulcrum, as shown in FIG. 4(b), and enters an inclined state. Hereinafter, this position will be referred to as a temporary attachment position.

By pressing down, the lid release lever 49 releases the guide pin 52.
is loosely fitted into the guide groove 48 shown in FIG.
The reel is also rotated to release the reel lock.

When the lid 32 is opened, the tape cassette 31 tries to move backward inside the cassette holder 41 due to the reaction force, but at that time, the cassette guide 59, which is integrally formed with the reel lock release member 56, is already attached to the tape cassette 31.
1, the position of the tape cassette 31 within the cassette holder 41 does not change. At this time, the locking member 61 also locks the cassette holder 41.
The positions of the lid release lever 49 and the reel lock release member 56 are locked, and this positional relationship is maintained throughout the period from the temporary mounting position to the mounting position.

When the tape cassette 31 is temporarily installed, a temporary installation detection switch (not shown) is turned on, the installation motor (not shown) starts rotating, and this rotational force is transmitted to the arm 83 via a transmission means such as a gear. The arm 83 is rotated counterclockwise around the synchronization shaft 85. This allows the cassette holder 4
1, the guide pin 52 moves horizontally in the guide groove 48 on the front side, and is supported by the support pin 87 on the rear side, and the synchronous shaft 85
By rotating the reel 34 as shown in FIG. 4(C),
and moves to the mounting position where the reel stand 21 is engaged. At the same time, the bottom opening 36 of the tape cassette 31 is placed in the temporary mounting position.
The tape is pulled out by a tape pull-out post (not shown) inserted into the magnetic tape 37, and the pulled-out magnetic tape 37 is wound around the cylinder 24. Then, signals are recorded and reproduced on the magnetic tape 37 wound around the cylinder 24.

Next, the operation when taking out the cassette will be explained. When removing a cassette, the movement is the opposite of when inserting a cassette.

That is, when the eject switch (not shown) is pressed, the mounting motor (not shown) rotates in the opposite direction to the direction during mounting, and the tape pull-out post (not shown) is inserted into the bottom opening 36 of the tape cassette 31. At the same time, the arm 83 is rotated clockwise around the synchronization shaft 85. As a result, the cassette holder 41 moves from the mounting position shown in FIG. 4(C) to the temporary mounting position shown in FIG. 4(b).
4 and the reel stand 21 are released, the magnetic tape 37 is still being pulled out, and the magnetic tape 37 is wound around the cylinder 24. While the magnetic tape 37 is being moved to the temporary attachment position, the magnetic tape 37 is still being pulled out. need to take it. This tape winding is achieved by rotating the winding drive lever 79 midway through the rotation of the arm 83, thereby causing the tape winding slider 71 to slide and rotate the reel 34.

Although this tape winding was not mentioned in the mounting operation, the magnetic tape 37 is loosened during mounting. There is no problem in loosening the magnetic tape 37, considering that the tape is also wound around the cylinder 24 during the cassette mounting operation.

When the arm 83 rotates to the temporary mounting position, the mounting motor (not shown) stops rotating and the arm 83 is locked. At the same time, a release rod (not shown) is released from the locking member 61.
and rotates the locking member e1 counterclockwise. As a result, the lock by the lock member 61 is released, and the lid release lever 49 is rotated counterclockwise relative to the cassette holder 41 by the action of the torsion spring 53, and the lid 32 is closed, and the lock release member 56 is rotated. is also rotated clockwise to lock the IJ+ lever 34. Further, the guide bin 52 moves to a position where it comes into contact with the right end of the guide groove 48 shown in FIG. 1, and the entire cassette holder 41 rises to the cassette attachment/detachment position shown in FIG. 4(a).

In the embodiment, it is assumed that the lid opening lever 49 rotates, but since it is sufficient to achieve the purpose of opening the lid, various movements other than rotation are possible.

In addition, although the reel lock release member 56 is also rotated,
Since it is only necessary to achieve the purpose of unlocking the reel, it is possible to move the reel in a variety of ways, not just rotation. moreover,
Although it is assumed that the cassette guide 59 can also be rotated, it is possible to move the tape cassette 31 in a variety of ways other than rotation, since it is only necessary to achieve the purpose of regulating the position of the tape cassette 31. Further, although the cassette guide 59 is bent and abuts on two places on the rear surface 35 of the tape cassette 31, it can be changed into various shapes as long as the position of the rear surface 35 of the tape cassette 31 is controlled in a well-balanced manner. Also, a connecting pin 54 is attached to the lid release lever 49. A linear elongated hole 6 is formed in the reel lock release member 56 integrated with the cassette guide 59.
0 is assumed to be interlocked, but of course the elongated hole 60 is not limited to a straight line, the arrangement of the connecting pin 54 and the elongated hole 60 may be reversed, and the interlocking method is not limited to this method. It is possible to change the method.

Effects of the Invention As described above, the present invention includes a cassette holder that holds and guides a tape cassette containing a magnetic tape, and a cassette holder that is placed in the cassette holder and comes into contact with the rear surface of the tape cassette to regulate the position of the tape cassette. By providing a cassette guide that moves the tape cassette, and a moving means that moves the cassette guide between a first position where it contacts the rear surface of the tape cassette and a second position where it does not contact the rear surface of the tape cassette, the reel and the reel stand can be engaged with each other. By bringing the cassette guide into contact with the rear surface of the tape cassette at the position before mating, the tape cassette can be guided and held in a fixed position within the cassette holder.
At that position, the lid is opened and the reel lock is released, allowing the magnetic tape to be pulled out. From that position, the tape cassette is guided by the cassette holder to the position where the reel and reel stand engage, while the magnetic tape is pulled out and inserted into the cylinder. By winding the tape, there is no need to move the chassis to bring the cylinder and tape cassette closer together, and only one chassis is required.

Since only one shunt is required, the tape cassette and cylinder can be kept close to each other at the cassette loading position, and the VCR can be made thinner, thereby making the VCR more compact. Furthermore, the advantage of using only one chassis is that all the parts related to tape transport are mounted on the same chassis, improving the positional accuracy between the parts. As a result, it is also possible to obtain the effect that the quality of the recording/reproduction signal is improved.

Further, a cassette holder for holding and guiding a tape cassette containing a magnetic tape, a reel lock release member disposed in the cassette holder for releasing the reel lock of the tape cassette, and provided integrally with the reel lock release member. By including a cassette guide that restricts the position of the tape cassette in the cassette holder by coming into contact with the rear surface of the tape cassette, the number of parts can be reduced by integrating the reel lock release member and the cassette guide. At the same time, there is no need to drive the two components using separate mechanisms, which simplifies the drive mechanism and requires less space for installation. - Also includes a cassette holder that holds and guides a tape cassette containing magnetic tape,
a lid opening means disposed on the cassette holder for opening the lid of the tape cassette; and a lid opening means disposed on the cassette holder for abutting against the rear surface of the tape cassette in conjunction with the lid opening means, thereby opening the lid of the tape cassette. By including the cassette guide that regulates the position within the cassette holder, by interlocking the lid opening means and the cassette guide, there is no need to drive these two with separate mechanisms, and only one is driven. The drive mechanism is simple and requires less space for installation. Further, the timing of opening the lid and regulating the position of the tape cassette by the cassette guide can be easily matched or shifted.

Furthermore, a cassette holder for holding and guiding a tape cassette containing a magnetic tape, a lid opening means disposed in the cassette holder for opening the lid of the tape cassette, and a lid opening means disposed in the cassette holder for opening the lid of the tape cassette. By providing a reel lock release means for interlockingly releasing the reel lock of the tape cassette, by interlocking the lid release means and the reel lock release means, there is no need to drive these two with separate mechanisms; Since it is only necessary to drive one side, the drive mechanism is simple and requires less installation space. Further, the timing of opening the lid and releasing the reel lock can be easily matched or staggered.
