With reference to Fig. 2,3 and 4, the magnetic recording of exemplary embodiments and transcriber 100 are provided according to the present invention, and comprise tape transport 40 that rotary head cylinder 31 is installed, cam wheel 51, main slide unit 53, extrusion lever 55, pivot rotaring lever 61, see arm 63 and elastomeric element 65 again.
Except bar base portion assembly 32 and 33 and drum motor 36, the tension rail unit 41, fixed bar 42 and the capstan motor 43 that are used for the tape rotating operation of Bootstrap Loading also all are installed in tape transport 40.Tension rail unit 41 comprises tension arm 41a, and it rotatably cooperates with cam wheel 51 and is installed in the tension rail 41b that is used to guide tape on the end of tension arm 41a.Tension rail unit 41 moves to adjust its pressure on one's own initiative according to the tension force of the tape that rotates.
Capstan motor 43 comprises the capstan 43a that is used to guide tape.Capstan motor 43 provides driving force to two spools of tape to be placed thereon tep reel platform (reel table) 44 and 45.In particular, the tep reel 44 that is positioned at the left side is driven and is used to supply with tape, and the tep reel 45 that is positioned at the right side is driven and is used to strain tape.
As shown in Figure 4, main slide unit 53 also comprises the first cam shedding 53c, and the connection bump 55a of extrusion lever 55 inserts wherein.
Therefore, when main slide unit 53 when M2 direction shown in Figure 3 is slided, connection bump 55a slides along the first cam shedding 53c, and extrusion lever 55 is rotated counterclockwise with respect to pivot pin 55b.The expression lobes 63a that sees arm 63 again makes and see that again arm 63 moves on the R direction shown in Fig. 5 A with the second cam hole 55c interlocking and motion.
See that again arm 63 rotatably is equipped with turning axle 69 on tape transport 40.See again bar 64 on the free end of seeing arm 63 again, be mounted for providing fixedly tension force to tape to support.
Like this, turning axle 69 rotations that pivot rotaring lever 61 is identical relatively with seeing arm 63 again, and preferably, pivot rotaring lever 61 is seen the interference of arm 63 so that specific wholesale distance is rotatably installed on the tape transport 40 from the bottom of seeing arm 63 again to avoid runback.In addition, pivot rotaring lever 61 and see that again arm 63 interconnects by elastomeric element 65.
When elastomeric element 65 stretched, pivot rotaring lever 61 was extruded in the clockwise direction, and hold-down roller 62 adheres on the capstan 43a tightly.For this purpose, elastomeric element 65 is preferably by spring element, or elasticity or elastomeric material formation.
Now, having the magnetic recording of said structure and the driving method of transcriber 200 will more specifically be described with reference to Fig. 5 A, 5B, 6A, 6B and 7.
When tape cassete was placed on the tape transport 40, the loading mode that drives by drum motor 36 was implemented in step (S10).That is, cam wheel 51 causes main slide unit 53 to move on the M1 direction in the direction rotation of the state shown in Fig. 5 A with arrow L.Then, shown in Fig. 5 A, rotate to the angle of appointment in the counterclockwise direction at step (S11) extrusion lever 55.That is, when main slide unit 53 when the M1 direction is moved, the connection bump 55a of extrusion lever 55 moves along the first cam shedding 53b of main slide unit 53.Correspondingly, extrusion lever 55 is rotated counterclockwise with respect to pivot pin 55b.
When extrusion lever 55 rotates to the angle of appointment in the counterclockwise direction, see that again arm 63 and pivot rotaring lever 61 rotate with the R direction together in step (S12).That is, slide along hole 55c with the expression lobes 63a of the second cam shedding 55c interlocking of extrusion lever 55, the result sees that again arm 63 is with the clockwise R direction rotation with respect to turning axle 69.Because pivot rotaring lever 61 by elastomeric element 65 with see that arm 63 adheres to tightly again, so pivot rotaring lever 61 and see that again arm 63 rotates to the angle of appointment together and tape is pulled to the capstan side.At this moment, tape 70 does not also adhere to capstan 43a by the hold-down roller shown in Fig. 5 B tightly.In addition, because seeing again bar 64 is placed is close to hold-down roller 62, come runback to see that the tension force of bar 64 also is not applied to tape 70, so tape is released.
After being drawn out tape cassete, the tape that is loaded rests in wait (stand by) pattern and is transfused in step (S13) until play signal, and play mode is implemented in step (S20).
In order to implement play mode in step (S20), the main slide unit 53 of state shown in Fig. 5 A slides as much as possible in the M1 direction and is further rotated extrusion lever 55 in the counterclockwise direction to go up the Ministry of Education in step (S21), then, as shown in Figure 6A, extrusion lever 55 is rotated the counter clockwise direction to furthest extent.
Answering of state shown in Fig. 5 A sees that arm 63 is further rotated on R direction as shown in Figure 6A, thus in step (S22) from pivot rotaring lever 61 separately.Elastomeric element 65 step (S23) go up on the T direction to see that again the distance between arm 63 and the pivot rotaring lever 61 stretches.Pivot rotaring lever 61 is extruded at directions X, that is, at the tension force of step (S24) by elastomeric element 65 towards capstan 43a.Therefore, with reference to Fig. 6 B, hold-down roller 62 adheres to capstan 43a tightly with tape 70, and sees that from answering of separating of hold-down roller 62 bar 64 goes up the tension force that tape is provided appointment in step (S25).
Effectively, above-mentioned steps (S21), (S22), (S23), (S24) and (S25) almost generation simultaneously.But, in exemplary embodiments, the place that these steps number in order and are sent to description power.
When tape was adhered to capstan 43a tightly by the tension force that applies, tape began to rotate in step (S26).Tape is in step (S26) rotating process, and information can be recorded to tape respectively or reproduce from tape.At this moment, the tension force that is applied to tape can pass through tension rail unit 41 Be Controlled, shown in Fig. 2 is detailed.
Subsequently, if stop signal is transfused in step (S27) in the play mode process of step (S20), the stop mode that is used to stop tape being implemented in step (S30).More specifically, the main slide unit 53 of state shown in Fig. 6 A is replied the distance of appointment on the M2 direction in stop mode, and extrusion lever 55 upward rotates on certain angle on the clockwise direction shown in Fig. 5 A in step (S31).See that step (S33) and answering of extrusion lever 55 interlockings arm 63 is by the position of answer near pivot rotaring lever 61, shown in Fig. 5 A and 5B then.Therefore, stretched elastic part 65 is shunk, and tension force is released in step (S33).As a result, hold-down roller 62 to the adhesion of capstan 43a is released, and simultaneously, runback is seen bar 64 provides to the tension force of tape and is released in step (S34).Like this, this just may prevent that in the stop mode of step (S30) tape from resting on tension, like this to prevent any infringement to tape.
As mentioned above, magnetic recording of the present invention and transcriber 200 have the structure of simplification, wherein, see that again arm 63 is utilized so that hold-down roller 62 is adhered to capstan 43a tightly.
In addition, see that again rotatablely moving of arm 63 can be by the driving force Be Controlled of main slide unit 53.This also feasible tension force that may in stop mode, adjust on the tape.So,, as require cam wheel control tension rail unit according to the magnetic recording and the no longer extra control of a lot of parts of needs of transcriber of the embodiment of the invention.Because the part count that requires reduces, so the manufacturing expense of magnetic recording and transcriber can be lowered.
In addition, only use a tape transport not have auxiliary tape transport according to the magnetic recording of the embodiment of the invention and transcriber as conventional apparatus.Because pivot rotaring lever and see that again arm is coaxially installed, the driving force of main slide unit can be used to control both.By this simplified structure, a plurality of parts can be deleted, cause device general assembly (TW) and described install the remarkable reduction of manufacturing cost.
In addition, according to embodiments of the invention, by the driven arm of seeing again of the driving force of main slide unit, hold-down roller can be adhered to capstan tightly by control.
Equally, see rotatablely moving of arm again by controlling, it may discharge the tension force on the tape in stop mode.
Correspondingly, this record of the present invention and transcriber are characterised in that the cost than conventional apparatus less components and reduction.Therefore, being used for design process in magnetic recording and the more spaces of transcriber internal fixation becomes and is more prone to.When making, thereby the number of assembling steps of minimizing is boosted productivity.
