Description
SPECIFICATION Cassette loading system
This invention relates to cassette loading systems for magnetic recording and reproducing units, and more particularly it is concerned with a cassette loading system for automatically loading a magnetic recording and reproducing unit with a magnetic tape cassette by inserting same through the front of the magnetic recording and reproducing unit.
For use with a magnetic recording and reproducing unit, proposals have in recent years been made to use a system for loading the unit with a cassette by inserting same in a horizontal position through the front of the unit. In this system of loading a magnetic recording and reproducing unit with a magnetic tape cassette, the cassette inserted through the front of the unit is generally withdrawn parallel to a base plate of the unit to a predetermined position and then moved downwardly on to the base plate. One example of this type of cassette loading system of the prior art is disclosed in Japanese
Patent Application Laid-Open No. 125569/80.
This type of cassette loading system is intended to facilitate the operation of loading a magnetic recording and reproducing unit with a magnetic tape cassette to thereby improve operability.
However, some disadvantages are associated with the type of cassette loading system described hereinabove. When the unit is loaded with a cassette by this system, it is necessary to move the cassette horizontally and then downwardly. This makes the mechanism for realizing the movements of the cassette complex. When this complex mechanism is used, the problem arises that trouble might occur when the cassette is switched between a horizontal movement and a vertical movement.
Accordingly an object of this invention is to provide a cassette loading system having a smaller number of parts and simpier in construction than the prior art.
Another object is to provide a cassette loading system of high reliability in performance.
The outstanding characteristic of the invention enabling the aforesaid objects to be accomplished is that means for regulating the posture of the cassette is completely separated from guide means for controlling the movement of the cassette along a predetermined path in performing a cassette loading operation and that the two means are made to continuously function in spite of the cassette moving in an inward movement and a downward movement successively. To this end, a linkage is used as means for regulating the posture of the cassette and a
mechanism comprising pivotal links, guide slots and
pin members is used as guide means. The cassette
posture regulating means and the guide means are
made to operate in a coordinatedfashion,tothereby reduce the number of parts used and to improve the
reliability of performance.
Additional and other objects, features and advantages of the invention will become more apparent when the following description is considered in
conjunction with the accompanying drawings.

An embodiment of the invention as applied to a helical scan type video tape recorder (VTR for short) will be described by referring to the accompanying drawings.
Fig. 1 is a plan view of a VTR provided with the cassette loading system according to the invention, wherein a base plate 1 for supporting the mechanical system of theVTR has secured thereto an auxiliary base plate 2 supporting thereon various parts of the tape traveling system. These parts will be described one after another. As shown, guide rollers 3a and 3b and inclined posts 4a and 4b serving as tape withdrawing guide members are arranged near one side of the auxiliary base plate 2. The guide roller 3a and inclined post 4a are secured to a slide member 5a while the guide roller 3b and inclined post 4b are secured to a slide member 5b.After a cassette loading operation is completed, the slide members 5a and Sb are moved along guide grooves 6a and 6b respectively formed on the auxiliary base plate 2 by means of a tape withdrawing mechanism located on the undersurface of the auxiliary base plate 2 until support shafts of the guide rollers 3a and 3b are brought into abutting engagement with positioning members 7a and 7b respectively to bring the slide members 5a and 5b to a halt. When the cassette loading operation is completed, the tape is located between the tape withdrawing guide members 3a, 3b, 4a and 4b and a head drum 8 and payed out of the cassette as the slide members 5a and 5b move and wound on the head drum 8.A post 9 is secured to the auxiliary base plate 2 in a position leftwardly of the head drum 8, and an eraser head 11 and an impedance roller 12 are secured on a base member
10 pivotable about the post 9. Another post 13 is secured to the auxiliary base plate 2 in a position
rightwardly of the head drum 8, and a partial eraser
head 15 and a sound control head 16 are secured on
another base member 14 pivotable about the post
13. A fixed guide post 17 and a capstan 18 are
located on the auxiliary base plate 2 in the vicinity of the post 13, and a pinch roller 21 is secured on still another base member 20 pivotable about still another post 19.
Reel decks 22a and 22b are rotatably supported on the base plate 1, in addition to the aforesaid members.
The arrangement of the principal parts of the tape traveling system has been described hereinabove.
The construction of one embodiment of the cassette loading system in conformity with the invention will be described by referring to Figs. 1-4 inclusive. In the figures, a stage frame 23 for the cassette is located on the cassette insertion side (in a lower portion as seen in Fig. 1) of the base plate 1 and provided with a pair of stopper means 24a and 24b on its upper portion and a pair of resilient members 25a and 25b above the surface of its lower portion. Connected to opposite sides of the stage frame 23 for pivotal movement through pin members 26a and 26b are link bars 27a and 27b respectively which have other link bars 29a and 29b connected to their central portions through pin members 28a and 28b for pivotal movement relative to each other.The link bars 29a and 29b have pin members 30a and 30b connected to one end thereof respectively, the pin members 30a and 30b being respectively received in slots 31 a and 31 b formed at side surfaces of the stage frame 23 for rotational and sliding movements (the slot 31b not being shown). Pin members 32a, 32b, 33a and 33b are connected to end portions opposite the end portions of the link bars 27a, 27b, 29a and 29b which are connected to the side surfaces of the stage frame 23. The pin members 32a, 33a and 32b, 33b are respectively received in slots 35a and 35b of brackets 34a and 34b attached to opposite sides of the base plate 1 for rotational and sliding movements.In this arrangement, the link bars 27a, 29a and 27b, 29b are located in a manner to cross each other as shown in Fig. 4.
The brackets 34a and 34b are further formed with
L-shaped slots 36a and 36b which respectively receive for sliding and rotational movements pin members 37a and 37b secured to the side surfaces of the stage frame 23. the pin members 37a and 37b are further received in slots 39a and 39b (39a not being shown) formed in pivotal links 38a and 38b respectively for sliding and rotational movements. The pivotal links 38a and 38b are fitted for pivotal movement to shafts 40a and 40b secured to the brackets 34a and 34b and further supporting partially toothed gears 41 a and 41 b respectively. The pivotal link 38a and partially toothed gear 41 a and the pivotal link 38b and partially toothed gear 41 b can rotate relatively to each other in the toothless portion of the respective gear.Resilient members 43a and 43b (43a not being shown) are arranged between pin members 42a and 42b (42a not being shown) secured to the partially toothed gears 41 a and 41 b respectively and raised portions formed in the pivotal links 38a and 38b. Thus the pivotal links 38a and 38b are normally urged by the biasing forces of the resilient members 43a and 43b in the same direction. The partially toothed gears 41 a and 41 b are in meshing engagement with synchronous
gears 44a and 44b respectively secured to opposite
ends of a synchronous shaft 43 extending through the brackets 34a and 34b for rotation.A worm wheel 45 is secured to the end of the synchronous shaft 43 outwardly of the synchronous gear 44b. In Fig. 3, a motor bracket 46 is secured to the bracket 34b located below the worm wheel 45 for supporting a motor 47 and a worm shaft 48 having a worm gear 49 secured thereto to mesh with the worm wheel 45.
Belt pulleys 51 and 52 are secured to end portions of a rotary shaft 50 of the motor 47 and the worm shaft 48, and a belt 53 is trained over the belt pulleys 51 and 52.
Operation of the cassette loading system of the aforesaid construction will now be described.
Referring to Fig. 1, the cassette is inserted into the stage frame 23 from the bottom of the plane of the figure and parallel thereto, and its position is regulated by the stopper means 24a and 24b in the rear of the stage frame 23. As soon as the cassette is inserted, it is forced by the biasing forces of the resilient members 25a and 25b located in the surface of the stage frame 23 against the surface of the stage frame 23 and securely held in place. Upon completion of insertion, the motor 47 is actuated after the presence of the cassette is sensed. Referring to Fig.
3, rotation of the motor 47 is transmitted to the worm gear 49 via the rotary shaft 50, belt pulley 51.
belt 53, belt pulley 52 and worm shaft 48. Rotation of the worm gear 49 is transmitted to the worm wheel 45 with being reduced to a predetermined speed, and further transmitted from the worm wheel 45 to the synchronous gears 44a and 44b via the synchronous shaft 43. Rotation of the synchronous gears 44a and 44b are transmitted respectively to the partically toothed gears 41 a and 41 b from which rotation is transmitted via the resilient members 43a and 43b to the pivotal links 38a and 38b respectively. As the pivotal links 38a and 38b move in pivotal movement, the pin member 37a received in the slots 36a and 39a and the pin member 37b received in the slots 36b and 39b begin to move in the L-shaped slots 36a and 36b respectively.The pin members 37a and 37b being secured to the side surfaces of the stage frame 23, the stage frame 23 and hence the cassette inserted in the stage frame 23 begins to move along the L-shaped slots 36a and 36b as the pin members 37a and 37b move therein.
Referring to Fig. 3 again, when the pin members 37a and 37b have moved to the corners of the
L-shaped slots 36a and 36b, the direction of movement of the pin members 37a and 37b is altered by 90 degrees and they move downwardly toward the base plate 1. At this time, lower cutouts of the stage frame 23 shown in Fig. 1 are located immediately above the reel decks 22a and 22b, and reel openings of the cassette within the stage frame 23 are in alignment therewith in position. When the pin members 37a and 37b have moved to the end of the
L-shaped slots 36a and 36b respectively in Fig. 3,
reels of the cassette within the stage frame 23 are fitted on the reel decks 22a and 22b and the stage frame 23 is brought to a halt by the stopper means
located on the base plate 1. At the same time, the pin
members 37a and 37b and the pivotal links 38a and
38b are rendered inoperative. However, the partially toothed gears 41a and 41b continue to rotate as they
are driven by the motor 47, but the motor 47
becomes inoperative as the toothless portions of the
gears 41a and 41 are brought at one end surface
thereof into contact with the pivotal links 38a and
38b, with the gears 41 a and 41 b also becoming
inoperative. At this time, the resilient members 43a
and 43b are expanded by a predetermined amount
and the stage frame 23 is forced by the biasing forces of the resilient members 43a and 43b against the stopper means on the base plate 1.Since the
rotational force of the motor 47 is transmitted via the worm gear 48 and the worm wheel 45, the pivotal
links 38a and 38b and partially toothed gears 41a and 41 b are kept in an inoperative position by virtue of the self-locking function between the worm wheel 45 and the worm gear 49.
In the operation described hereinabove, the parts on the opposite side surfaces of the stage frame 23 operate in synchronism by means of the synchronous shaft 43 and the synchronous gears 44a and 44b. The posture of the stage frame 23 is regulated by the link bars 27a, 29a and 27b, 29b, the pin members 26a, 30a, 32a and 33a and 26b, 30b, 32b and 33b located at the opposite end portions thereof and the pin members 28a and 28b located in the central portions thereof in such a manner that it is kept parallel to the slots 35a and 35b formed in the brackets 34a and 34b respectively. Fig. 5 shows the link bars 27b and 29b in positions when the downward movement of the stage frame 23 has been completed.
The aforesaid description refers to an operation for loading the magnetic recording and reproducing unit with a cassette. The cassette inserted in the stage frame 23 can be withdrawn therefrom by following the aforesaid steps in reverse.
In the embodiment shown and described hereinabove, the link bars have been described as crossing each other. However, the invention is not limited to this specific arrangement of the link bars and they may be located parallel to each other, as shown in
Fig. 6. More specifically, link bars 54 and 55 are pivotally connected at one end thereof to a lower portion of one side of a stage frame 56 through pin members 57 and 58 respectively and received at the other end thereof for rotational and sliding movements in a slot 62 formed in a bracket 61 through pin members 59 and 60. The cassette can be transferred in the same manner as described hereinabove and its description shall therefore be omitted. Fig. 7 shows the link bars 54 and 55 in position after completion of the loading with the cassette.
Figs. 8 and 9 show a mechanism which is general ly used for connecting a pin member at one end portion of a link bar for regulating the posture of the cassette with a slot formed in a bracket. More specifically, a roller 64 is fitted over a pin 63 joined by caulking to a link bar 29a, and an E-ring 65 is connected to the forward end of the pin 63 to prevent the roller 64 from coming off. A bracket 34a is formed with a slot such that the roller 64 is in contact with its end faces to thereby reduce friction produced when the pin 63 moves in sliding movement in the slot 35a and also reduce resistance offered by rotation thereof When a load applied by
rotational and sliding movements of one end portion
of the link bar in the slot is small, it is possible to use
a mechanism shown in Figs. 10 and 11. As shown, a sliding member 66 is formed integrally with a link bar 67 of a synthetic resinous material, and a hinge 58 of the same material is formed in the connection between them. The sliding member 66 is received in the slot 35a formed in the bracket 34a and moves in sliding movement in the slot 35a as the link bar 67 moves in sliding movement. rotational movement of the link bar 67 can be realized by bending the hinge 68.
From the foregoing description, it will be appreciated that the feature of the invention in which cassette posture regulating mechanism and the cassette traveling path regulating mechanism are completely separated from each other is conductive to improved reliability in the performance of the system, a reduced number of parts and a simple construction.
