BRIEF SUMMARY
FIELD OF ART
This invention pertains to a selective driving mechanism for a plurality tapes, which are driven in a coplanar relationship, wherein one of the tapes is endless and will playback outgoing message and the other is a standard tape for recording incoming messages and wherein a common capstan and two pinch-rollers alternately or sequentially drive said plurality tapes in a telephone answering and recording device.
BACKGROUND ART
Applicant has previously disclosed (in PCT/JP28/00009) the common driving mechanism of two parallel coplanar tapes which are located in coplanar relationship of the tapes is endless for playback of the outgoing message and the other is a tape for recording the incoming message for the telephone answering and recording device. JP, Y2, 54-33378 and JP, A, 54-87510 disclosed separate driving mechanisms which drive said two tapes alternately or sequentially. According to the drawings, in the specifications of the above two publications, it seems that the incoming message tape is driven by its own pinch-roller and by a common capstan while the the pinch-roller for the incoming message tape is not engaged with the common capstan. But unexpectedly, the incoming message tape shall be taken up by the common take-up reel spindle so long as conventional cassette tape decks are used for these purposes, because the take-up reel spindle is driven in conjunction with the capstan and a plurality of idlers through a friction clutch. So, even if the capstan is not engaged by one of the pinch-rollers, the incomining messages tape must still be driven by the common take-up reel spindle. This invention solves this disadvantage by a novel mechanism.
DISCLOSURE OF THIS INVENTION
This invention has such a structure that, in the mechanism which drives the plurality of cassette tapes consisting of an upper layer and a lower layer, which are placed on common reel-tables, alternately by its selective driving function with a common capstan and its own pinch-roller for each of the plurality of tapes, while one of the tapes is being driven by a common capstan and its own pinch-roller, the other tape shall not be taken up by common spindle of the take-up reel table.
BRIEF DESCRIPTION OF DRAWINGS
The details of this invention will be described in connection with the accompanying drawings, in which;
FIG. 1 shows a side view of the common capstan, pinch-roller and two independent tapes.
FIG. 2 shows a side view of the common capstan, two pinch-rollers and two coplanar tapes in this invention.
FIG. 3 is a plan drawing that shows the whole mechanism of this invention.
THE BEST EMBODIMENT OF INSTANT INVENTION
The details of this invention shall be explained hereinafter, referring to the accompanying drawings. FIG. 1 shows the relation between a common capstan and a common pinch-roller in said PCT/JP78/00009. T-1 is the outgoing message tape, and T-2 indicates the incoming message tape. FIG. 2 shows the independent supporting mechanism for two pinch-rollers which is so constructed as to allow selective engagement of each pinch-roller for each of the outgoing message tape and the incoming message tape to the common capstan 4 by selecting the pinch-roller arms 17 and 18 which are on a common axle shaft 19. FIG. 3 indicates the principle of the basic mechanism for accomplishing the object of this invention in a tape deck which has such a selective engagement of the pinch-roller to a common capstan as shown in FIG. 2. In FIG. 3, 1 is the motor, 2 is the belt, 3 is the flywheel, and 4 is the capstan which is indicated by the same numeral as that shown in FIG. 2. 5 is the pinch-roller for T-1, and 6 is the pinch-roller for T-2. Both of those pinch-rollers are described by one circle since the drawing is a top-plan view. 10 is an actuating lever to actuate a few idlers for driving, which is movably supported around the shaft 11. For example, the moving direction of 10 indicated by an arrow mark FW means fast forward, and RW means rewind. In this embodiment, the driving pulley 13 which is supported on the
