Abstract

PURPOSE:To suppress a deck height to the minimum by moving the second chassis so that the upper end of a pinch roller and a tape guide is positioned in the lower part than the lower end of a tape, when drawing out the tape, and the center part of the tape coincides roughly with the center part in the width direction of the guide post in a drawing-out machine. CONSTITUTION:When a tape cassette 17 is installed, a drawing-out post 18 is guided and moved by a guide rail, drawing-out posts 6, 7 turn and move, and as for a chassis 16, the upper end part of a pinch roller 9, tape guide posts 11, 12 and guide rollers 13, 14 is positioned in the lower part than the lower end part of a tape 19. After the drawing-out posts 18, 6 and 7 have been moved, as for the chassis 16, the pinch roller 9, the tape guide posts 11, 12 and the guide rollers 13, 14 go into a tape loop formed by the drawing-out posts 18, 6 and 7, and they are made to ascend by a link mechanism until the center point A of the guide rollers 13, 14 attains the almost same height as the center line B of the tape 19. In such a way, the deck height can be suppressed to the minimum.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rotary head type magnetic recording/reproducing device.

Conventional configurations and their problems In recent years, rotating head type magnetic recording and reproducing devices (hereinafter referred to as VTRs) have rapidly become popular in general households, and consumer demands have become extremely diverse, leading to the emergence of new types of VTRs. It has come to be expected.

Many modern audio cassette decks are installed in dedicated racks, and when amplifiers, tuners, etc. are arranged vertically, the deck itself is designed so that the cassettes can be inserted easily and the tapes inside the cassettes can be seen from the front. There has been a shift from a horizontal type to an almost vertical (□vertical) type, and due to this ease of operation, VTRs are also based on the same concept, and there is a strong demand for vertical VTRs, but until now, I don't think a VTR like this exists.

In the case of a VTR, if a conventional VTR'i is simply constructed by standing up, the one-turn head cylinder is located above or below the tape cassette, which inevitably increases the height of the deck, which is not good in terms of design. Since it requires a lot of space in the height direction, it has the disadvantage that it is difficult to install audio decks and tuners one on top of the other, making it unpopular with consumers.

OBJECTS OF THE INVENTION The present invention therefore obviates the above-mentioned drawbacks and minimizes (
The purpose of this project is to provide a vertical VTR with a new image, which has a height that is not much different from the width of a tape cassette.

Structure of the Invention The present invention provides a method for mounting a tape cassette in a cassette mounting section,
The first step is to pull out the tape in a direction parallel to the tape feeding direction from this tape cassette and expand the tape loop.
Second. and a second chassis having a capstan, a pinch roller, a rotating head cylinder, and at least two tape guide posts for wrapping the tape around the cylinder.
The upper ends of the tape guide post and the pinch roller are located below the lower end of the tape, and after being pulled out, the second chassis is moved in the tape width direction to a height where the tape center and the width direction center of the guide post almost match. It is something.

DESCRIPTION OF THE EMBODIMENTS Next, an embodiment of the present invention will be explained using the plan view and front view shown in FIGS. 1A and 4B to FIG. 4B. Figure 1A
, B, the guide rail 3 which slidably held the supply reel stand 1, the take-up reel stand 2, and the drawer post 18 is connected to the chassis 4 to which the tape guide post 5.22 is fixed.
The drawer post 6 and the drawer post 7 are also rotatably attached to the chassis 4. Also, a capstan 8, a pinch roller 9, a rotating head cylinder 19, a tape guide post) 11.12, and a guide roller 13.14.
15 is attached to a link mechanism (not shown) held by the chassis 4, and is configured to be movable in a direction substantially perpendicular to the plane of the chassis 4.

Note that 22 is a guide post, 23 is an audio/control head, and 24 is a loading base.

Next, the operation will be explained. When the tape cassette 17 is installed, the drawer post 18 is guided by the guide rail 3 and moves to the position B in FIG. 2, and the tape 19 is drawn out. Further, the drawer posts 6, 7 are rotated and moved to the positions shown in FIG. 2, M and B, respectively. At this time, the chassis 16 is
, tape guide post 11.12 and guide roller 13
．． The upper end of the tape 14 is located further below the lower end of the tape 19.

After the drawer bosses 1B, 6.7 are moved to the position B in FIG. 2, the chassis 16 is moved to the pinch roller 9, tape guide post 11. 12 and guide roller 13.14 enter the tape loop formed by the pull-out posts 18, 6.7, and the center point A of the guide roller 13.14 is approximately at the same height as the center line B of the tape 19. The link mechanism will raise it to the position where it is.

After the chassis 16 further rises, the top post 11.12 and the kit roller 13.14 are moved to the guide groove 2.
Guided by 0 and 21, the fourth southerner moves to the position of B, and the tape 19 can be rotated.
Vertical V with a new image that fully meets consumer demand
It is possible to realize TR.
