Moreover, not only the rotary head but also the full erase head that erases all tracks on the tape and the linear track head that reads the servo signals recorded on the tape are arranged on both sides of the rotary head. Further, a mechanism for winding the tape around is required, and it must be arranged so as not to interfere not only with both mechanisms but also with traveling system parts such as the capstan shaft, pinch roller, and other fixed guides. It is extremely difficult to downsize the device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tape recorder having an improved tape loading device, which can be miniaturized and can be miniaturized even when a full erase head and a linear track head are incorporated. It is in.

[0005]

In order to achieve the above-mentioned object, a drive device having a mechanism for rotating a supply reel and a take-up reel and a tape arranged in a portion of the tape between the reels are run. And a rotary head that forms a space between the reel and the two reels and is arranged at a position related to the reel between the reels, and a tape that winds the tape around the rotary head and releases the tape from now on. A tape loading device including a loading device, the tape loading device being disposed on the opposite side of the tape from the rotary head and having two guide members for contacting the tape; and winding the tape around the rotary head. The rotary heads on both sides of the The first and second tape guides are made to move linearly or nearly linearly to and from the unloading position away from the rotary head that separates the tape, and the first position in the direction crossing the transport direction at the loading position. And a drive means for causing the tape guide to perform a second rotation that approximately coincides with the transport direction at other positions about the axis between the guide members.

[0006]

In the initial state, the guide member faces the magnetic surface of the tape hung between the supply reel and the take-up reel and is in the unload position on the side opposite to the rotary head across the tape.

Loading of the tape is initiated by the drive mechanism moving the slide along a linear guide. When the slide moves, the rotating mechanism causes each of the guide members to perform a second rotation that matches the moving direction of the slide, and moves each of the guide members toward the load position while maintaining this state. When the tape guide reaches the load position, the rotating mechanism causes each of the tape guides to make a first rotation in the direction intersecting the transport direction centering between the guide members, so that the tape is wound at a predetermined winding angle. It is wound around the rotary head and kept in this state. Unloading of the tape is done by the operation of the associated member in reverse of loading.

In the tape recorder of the present invention, the tape guide moves from the unloading position to the loading position while keeping the guide member aligned with the moving direction of the slide. The required space is much smaller, and the tape recorder with only the rotary head can be downsized, and the parts can be easily arranged without interfering with the running system parts such as the capstan shaft, pinch rollers, and other tape guides. You can do it. Furthermore, even if a fixed head such as a full erase head or a linear track head is installed, the tape guide rotates at the load position, so the center of rotation between the guide members in the tape guide that was first rotated at the load position. By arranging the fixed head in the vicinity, or by arranging the fixed head at a portion of the tape where the angle changes when the tape guide makes the first rotation in the load position, At the same time as rotating
The tape is wound around the rotary head and the fixed head, a mechanism for winding the tape around the fixed head is not required, and the space occupied by the tape guide for moving is small, which makes it extremely compact. You can get the tape recorder.

The cam plate 51 is of a disc shape having two cam grooves, is arranged between the slide 35 and the rotary base 41, and is engaged and fixed to the rotary shaft 43 of the rotary base. The spring 53 is arranged between the cam plate 51 and the slide 35, and always rotates the cam plate 51, the rotary base 41, and the guide members 36 and 37 in the direction of arrow C. The arm 52 has a roller 54 at one end, and a shaft 55 at the other end is held by a bearing on the slide 35. A coil spring 56 is arranged between the arm 52 and the slide 35, and the roller 54 of the arm 52 is connected to the cam plate 5
The guide member 36, 37 is locked in a position substantially parallel to the guide rail 33 while being engaged with the groove 1. The groove depth of the cam plate 51 and the spring force of the coil spring 56 are set such that the roller 54 of the arm 52 is displaced from the groove of the cam plate 51 when a relatively large force acts on the cam plate 51. .

The forced rotation of the tape guide 31 in the loading position is performed by a mechanism including a cam plate 61 near the rotary head 11 and contacts 57 and 58 on the tape guide 31. As shown in FIGS. 3 and 4, the contacts 57, 58 are in the form of pins, and are planted on the lower surface of the turntable 41 with the shaft 43 forming the center of rotation of the tape guide 31 interposed therebetween. . The cam plate 61 is arranged at the loading position of the tape guide 31, and
It is fixed to a member 61A supported by a base 33B supporting the guide rail 33. The cam plate itself has three cam grooves 62 to 64 as shown in FIG. The cam groove 62 has a width into which the shaft 43 fits, and is arranged in the extension direction of the guide rail 33. The cam groove 63 first comes into contact with the contact 57 when the tape guide 31 is moved to the load position, and the rotary table 4 is rotated about the shaft 43.
1 has a cam profile which rotates the contact 58 into the cam groove 64 and further rotates the turntable 41. When the rotary table 41 is rotated by a certain angle by the cam groove 63, the cam groove 64 comes into contact with the contact 58 to further rotate the rotary table 41 together with the cam groove 63 and the contact 57. It has a cam profile for moving the guide members 36 and 37 to the load positions on both sides of the full erase head 12. Guide plates 65 and 66 made of a material having a small friction coefficient such as tetrafluoroethylene resin are fixed to the portions of the cam plate 61 where the cam grooves 63 and 64 are formed. Contactor 57 in
Blocks 67 and 68 made of a highly rigid material such as metal are fixed to a portion where the position of 58 is fixed. The other groove of the cam plate 51 on the slide 35 fits on the roller 54 of the arm 52 when the guide members 36 and 37 are moved to the load position, and the cam plate 51 is locked at this position to lock the turntable 41. It is located in.

In recording and reproducing, the tape guide 3
When 1 reaches a position just before the end of the linear movement, the contact 55 on the rotary table 41 of the tape guide 31 comes into contact with the cam groove 62 of the cam plate 61. When the tape guide 31 continues to move further, the contact 57 is pushed by the cam groove 63, and the rotary base 41 is rotated in the direction of arrow C by this, and the arm 5
The second roller 54 is disengaged from the groove of the cam plate 51, and the lock or latch of the rotary table 41 is released. At this time, the rotary base 41 is rotated by the spring force of the spring 56 between the slide 35, and these spring forces make contact between the contact 57 and the cam groove 63 and contact 66 and the cam. It acts as a force for maintaining contact with the groove 64. As the tape guides 31 and 32 move further linearly, the contact 58 comes into contact with the cam groove 64,
The rotary base 41 is further rotated about the shaft 43 fitted in the cam groove 62 by the cam groove 63 and the cam groove 64. When the turntable 41 is rotated to a predetermined position,
The contact 57 is in the block 67, and the contact 58 is in the block 6
Each of the guide members 36, 37 is pressed against the rotary head 8 and is positioned at a predetermined position necessary for accurately winding the tape 18 around each of the rotary head 11 and the full erase head 12. At the same time, the roller 54 of the arm 52 fits into the groove of the cam plate 51 and locks the rotary base 41. When the tape guide 31 starts to return to the unload position, the cam groove 63 associated with the contact 57 and the cam groove 64 associated with the contact 58 cause the rotary base 41 to move to the cam plate 5.
When the roller 54 of the arm 52 is disengaged from the groove of the cam plate 51, the rotary base 41 is unlocked, the contact 57 is disengaged from the cam groove 63, and the contact 58 is disengaged from the cam groove 64. . When it comes out, the turntable 41 is reversed by the spring 53, and when the guide members 36 and 37 become substantially parallel to the guide rail 33, the roller 54 of the arm 52 fits into the first groove in the cam plate 51 and the turntable 41 is moved. The guide members 36 and 37 are locked, and the guide members 36 and 37 are moved to the unload position while being substantially parallel to the guide rail 33.

The guide members 36 and 37 in 1 and the guide posts 38 and 39 in the tape guide 32 are straight in the directions of the arrow A and the arrow B, respectively, in the postures that substantially coincide with the respective moving directions or in the postures that are slightly inclined with respect to the moving direction. The tape 18 is moved around to wind the tape 18 around the rotary head 11, and the tape guides 31 and 32 are unlocked at the winding position.
6 and 37 are forcedly rotated in the direction of arrow C about the shaft 43 and in the direction of arrow D about the shaft 44 between the guide members 38 and 39, so that the tape 18 on the rotary head 11 is rotated. The angle of the tape 18 wound around the guide members 36 to 39 changes due to the change in the posture of the tape guides 31 and 32 that is wound and is forced to rotate, and the tape 18 relative to the full erase head 12 and the linear track head 13 is changed. The winding is performed at the same time as the rotary head 11.

[0039]

As described above, according to the tape recorder of the present invention, the tape guide having the two guide members moves linearly substantially in line with the traveling direction to wind the tape around the rotary head. Since the space that the guide occupies when loading and unloading the tape can be reduced, the size can be reduced as compared with the conventional device.
