Abstract

PURPOSE:To load exactly a cassette on a cassette-positioning post by providing a member which forcibly pushes the cassette toward the reel base in case the cassette does not smoothly set at said post at lowering the cassette. CONSTITUTION:When a revolving lever 9 is moved in the direction of arrow A through B, bar-shaped protrusions 5 provided on both sides of a cassette holder 1 moves along a guide groove 7, so that the holder 1 moves horizontally from the cassette-inserting position to the position above the reel base 3, then lowers onto the reel base 3. During this process, a pressing lever 12, a pressing roller 14, and a pressing spring 16 apply pressing force on the cassette 2 to press it on the cassette-positioning post 17, however, there is sometimes a case the said loading on the post 17 can not be smoothly executed due to some a reason. In such a case, a sub-pressing spindle 15 provided on both inner surfaces of the cassette holder 1, the cassette 2 is loaded exactly on the post 17.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic tape cassette mounting device.

2. Description of the Related Art Conventionally, as a mounting device for magnetic tape cassettes in video tape recorders, etc., there is an automatic mounting device, the main part of which is shown in FIG. has been put into practical use.

Problems to be Solved by the Invention However, these conventional magnetic tape cassette automatic mounting devices have the disadvantage that the cassette may not be smoothly mounted on the cassette support post due to subtle reasons when the cassette is lowered; If the cassette is not fully seated and is held for a certain period of time, the compression spring that presses the cassette against the cassette support post will yield.
Means for Solving the Problems The present invention solves the above-mentioned drawbacks of the conventional art.During normal predetermined operations and operations, it is difficult to insert the cassette and raise the cassette. This device is provided with a member that forcibly presses the upper surface of the cassette upper half toward the reel stand when the cassette is not smoothly mounted on the positioning post when the cassette is lowered by force setting, without interfering with the opening and closing of the guard panel during lowering.

Function: By configuring as described above, even if the cassette is not installed smoothly on the positioning post due to mechanically delicate reasons, the cassette can be forcibly pushed toward the reel stand, and especially in automatic installation, it is possible to completely press the cassette. This makes it possible to realize a simple cassette loading operation.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. 1st
2, reference numeral 1 denotes a cassette holder for holding a VTR magnetic tape cassette (hereinafter simply referred to as a cassette) 2, which is moved by a moving means 4 between the cassette insertion position and the cassette operating position on the reel stand 3. It is made movable. That is, bar-shaped protrusions 6 are provided on both sides of the cassette holder 1, and the protrusions 6 are movably engaged in guide grooves 7 formed in a pair of left and right side plates 6 arranged on both sides of the cassette holder 1. Furthermore, on the outer side of the pair of side plates e, a rotary lever 9 is attached via the shaft body 8 in the direction of arrow A.
, B, the lever 9 is rotatably mounted, and the protrusion 6 is movably engaged in an elongated hole 10 formed in the rotary lever 9.

Therefore, when the rotary lever 9 is rotationally driven in the directions of arrows A and B by a drive device (not shown), the cassette holder 1 is moved between the cassette insertion position and the cassette operating position. Note that the guide groove 7 has a horizontal portion 7 and a vertical portion 7b.
Therefore, the cassette holder 1 moves horizontally from the cassette insertion position to a position above the reel stand 3, and then descends onto the reel stand 3. Reference numeral 12 denotes a pressing lever that is rotatable in the directions of arrows A and B via pivot shafts 11 installed on both sides of the cassette holder 1. A press support shaft 13 into which a press roller 14 is inserted and is rotatably attached to the press lever 12 is locked. Further, one end of a pressing spring 1e that is in the cassette operating position and acts as a pressing force to press the cassette 2 against the cassette positioning post 17 is locked to the pressing lever 12, and the other end of the pressing spring 16 is locked to the pressing lever 12. are secured to spring hooks 18 provided on both sides of the cassette holder 1. 16, when the cassette 1 is not smoothly attached to the cassette positioning post 17 for some reason during descent,
This is a sub-pressing shaft for forcibly pressing the upper surface of the cassette 2 toward the reel stand, and is implanted or attached to the inner surfaces of both sides of the cassette holder 1.

As shown in FIG. 2, in a conventional device that does not have a sub-suppressing shaft 16, the cassette 2 may not be installed smoothly on the cassette positioning post 17 due to subtle factors, and furthermore, However, in the present invention, the sub-pressing shaft 1
5, even if the cassette 2 is not installed smoothly, the cassette 2 can be forcibly pressed onto the cassette positioning post 17. In addition, when inserting the cassette,
The sub-suppressing shaft 16 is configured at a position where it does not prevent damage to the cassette insertion operation, and does not prevent damage to the opening and closing of the guard panel 2a of the cassette 2 when the cassette is raised and lowered.

Effects of the Invention As described above, according to the present invention, the cassette can be reliably mounted on the cassette positioning post, and it is also possible to prevent the pressing spring from yielding and the pressing force from decreasing.
