DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a recording and reproducing device such as video tape recorders (VTR) and more particularly, it relates to a cassette setting device for setting a cassette around which a magnetic tape is wound at the tape drive section in the video tape recorder.
BACKGROUND OF THE INVENTION
Those of the front loading type and of the linear skating type are well-known as the conventional cassette setting devices for the VTRs. In the case of the cassette setting device of the front loading type, the cassette horizontally inserted into the cabinet through a slot thereof is received and carried to the tape drive section in the cabinet by a carriage system and the cassette thus carried to the tape drive section is then carried by the carriage system to be picked up out of the cabinet through the slot thereof. In the case of the cassette setting device of the linear skating type, the whole of the tape drive section in the cabinet is carried outside the cabinet and the cassette is set directly at the tape drive section
In the former case, however, it is enough only to place the cassette at the carriage system in the cabinet but it is difficult for the operator to confirm whether or not the cassette is then reliably carried and set at the tape drive section in the cabinet This setting of the cassette in the cabinet therefore cannot satisfy the users. In the latter case, the users are satisfied in that they can reliably set the cassette at the tape drive section, but the whole of the tape drive system must be moved into and out of the cabinet. This makes the structure of the carriage system and the tape drive section quite complicated.
It is asked therefore to provide a cassette setting device that is simple in structure and capable of reliably setting the cassette at the tape drive section in the cabinet as seen in the case of the conventional linear skating type.
A cassette setting device of the tray type is now imagined as the one to meet the need, wherein a tray for carrying and holding the cassette is so arranged as to be freely inserted into and pulled out of the cabinet and the cassette is set at the tape drive section in the cabinet by the tray. In the case of the cassette setting device of the tray type, it is not enough only to arrange the tray in such a way that the tray can be freely inserted into and pulled out of the cabinet. The cassette placed in the tray must be carried to the tape drive section in the cabinet and the cassette thus set at the tape drive section must then be carried outside the cabinet. This needs various kinds of component parts to organically combine the tray with the tape drive section.
It is quite difficult to directly use those component parts of the conventional front loading and linear skating types in order to organically combine the tray with the tape drive section It is asked therefore to provide a cassette setting device having such a structure that allows the cassette to be more reliably carried into and out of the cabinet by simpler operation.
An object of the present invention is therefore to provide a cassette setting device of the tray type allowing the cassette to be more accurately and reliably set at and detached from the tape drive section in the cabinet.
SUMMARY OF THE INVENTION
According to an aspect of the present invention, there can be provided a cassette setting device comprising a cassette around which a magnetic tape is wound; a cabinet for housing therein a tape drive section at which the cassette is set; a tray arranged in the cabinet to receive the cassette therein and having a first position where the tray is projected from the front side of the cabinet and a second position where the cassette is set at the tape drive section in the cabinet; a carriage system for horizontally carrying the tray from the first position to a position above the tape drive section; a lifter system for carrying the cassette in the tray to the second position, while pressing and holding the cassette in the tray, to set the casse
