Abstract

PURPOSE:To incorporate a compact (C) cassette adaptor into a cassette loading device without increasing the size of the loading device by using effectively an upper space, etc., of a tape drive mechanism part as the holding space of a tray. CONSTITUTION:A cassette loading device contains a 2nd tray 19 which holds a C cassette adaptor 18 and is attached guidably to a 2nd supporting cover 29 and can be freely separated from a 1st supporting cover contained in a 1st tray 15 which stores selectively a full cassette or C cassette adaptor 18. Thus it is possible to set the holding position of the tray 19 at an optional position of the upper part of a tape driving mechanism part 30 requiring the adjustment and maintenance checks. As a result, the upper space of the part 30 can be effectively used as the holding space of the tray 19. Then the adaptor 18 can be incorporated into the cassette loading device without increasing its size.

Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Field of Industrial Application) The present invention relates to, for example, a VH3 system video tape recorder (VTR), and particularly relates to a VHS full cassette and a VHS compact cassette (C cassette). The present invention relates to a cassette loading device for loading an irregularly shaped tape cassette () into a tape drive position.

(Prior Art) Generally, a VTR is configured so that a C cassette can be used as a recording medium in addition to a normal full cassette. The C cassette adapter is inserted into an adapter, and the tape is driven by replacing the C cassette adapter with a full cassette and loading the cassette. This involves transporting full cassettes and irregularly shaped C cassettes to the tape drive position using a cassette loading device designed for full cassettes.
This is because it has to be loaded.

By the way, in such conventional VTRs, when using a C cassette instead of a full cassette, a separate C cassette adapter must be used, which makes the handling operation very troublesome. It had become.

Therefore, for VTRs, there is a strong demand to develop a cassette loading device that can use both a full cassette and a C cassette without using a separate C cassette adapter, and to improve its handling and operability. There is. In this case, it is not sufficient to simply incorporate a C cassette adapter; it is also required to improve the internal mechanism so that the adapter can be incorporated without increasing the size.

(Problems to be Solved by the Invention) As described above, the conventional cassette loading device has the problem that a separate C cassette adapter must be used, making the handling operation very troublesome. Was.

This invention was made in view of the above circumstances, and has achieved miniaturization without using a separate adapter.
It is an object of the present invention to provide a cassette loading device that can reliably attach and detach a plurality of tape cassettes of irregular shapes and improve handling operability as much as possible.

[Structure of the Invention] (Means for Solving the Problems) The present invention moves a large first tape cassette or a small second tape cassette from a cassette insertion position to a tape drive position to drive a tape drive unit. In the cassette loading device, the adapter is movably provided between the cassette insertion position and the tape drive position while holding one of the adapters in which the first tape cassette or the second tape cassette is accommodated. and this first tray.
The adapter accommodated in the tray is placed on standby for movement, and includes a second tray controlling an adapter accommodation position corresponding to the cassette insertion position and a standby position corresponding to the tape drive position; a tray connecting mechanism detachably connected to the first tray; and a tray connecting mechanism configured to transfer the adapter to the first tray to accommodate the second tape cassette, and to transfer the adapter to the second tray. an adapter transfer mechanism that allows the first tape cassette to be accommodated in the first tray; and a second tape that is inserted into the first tape cassette or the adapter by transferring the first tray. A tray transport mechanism that transports the cassette to the cassette insertion position and the tape drive position, and a support member that guideably supports the second tray and guides it to the adapter storage position and the standby position. be.

(Function) According to the above configuration, the second
Since the tray can be taken out separately from the first tray, the second tray can be placed in any desired position, such as above the tape drive mechanism where adjustment and maintenance are required. can. Therefore, the space above the tape drive mechanism, which conventionally was wasted space, can be effectively used as a standby space for the second tray, and the adapter can be built in without increasing the size. .
