Abstract

PURPOSE:To easily load a cassette by providing a holder for vertically movably supporting a tape cassette tray and reciprocatedly moving before and behind, a ramp for movably receiving the tray from the holder and a lock cancel pin on the bottom face of the tray. CONSTITUTION:At the time of loading, the tray 2 protrudes externally of a cabinet. At the time of mounting the cassette 9, the lock cancel pin 22 of the bottom face of the tray 2 enters the pin hole 93 of the cassette case 9 to cancel a lock mechanism. When the holder 3 moves into the cabinet 1 by a rack pinion mechanism, the tray 2 is released from the holder 3 at a moving end and received by the ramp 5. The tray 2 is lowered together with the ramp 5 in a ramp device consisting of the rack pinion and a spring, and engaged at a prescribed loading position. A taking out operation is opposite to this sequence. According to this constitution, the lock can be automatically cancelled and the loading operation can be automatically performed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a loading device for a cassette, such as a tape cassette for a VTR, which has a locking mechanism in its case.

(Prior art) In conventional VTRs, by inserting a cassette into the opening of the cavity hotter (1), a loading device transports the cassette to a predetermined position and presses the cassette, and the reel is locked during the movement. An operation is being performed to release the mechanism. However, ■ For example, when a TR tape cassette is repeatedly fast-forwarded and stopped, the tape is tightly wound around the reel and locked.
) may get stuck firmly in the unevenness around the reel, and the cassette loading operation may proceed without being able to release the lock. In such a case, depending on the type of VTR, the cassette is not accepted and is ejected, or the tape is pulled out and wound around the cylinder in a loading process. If the tape is pulled out from the cassette without releasing the lock, unreasonable force is applied to the tape and mechanism, which may damage the loading mechanism and the tape cassette.

(Problems to be Solved) The present invention is capable of unlocking the tape cassette at the first step of loading the cassette, regardless of whether it is tightly wound or not. It reveals the device.

Furthermore, the present invention automatically performs unlocking and loading operations simply by placing the cassette on the cassette tray.
To provide a loading device that can easily load a cassette.

(Nari Yoko) The cassette tray (2) is the cassette holder (3).
The cassette holder is supported in a vertically movable manner, and is linked to a reciprocating device to move the cassette tray (2) back and forth between a loading position where it protrudes from the cabinet and a position where it is moved to the back of the cabinet, and then to a standby position at the back of the cabinet. Lifting platform (
5) to removably receive the cassette tray,
Recording a cassette tray by connecting the elevating platform to an elevating device;
It is raised and lowered to the playback position.

The cassette tray (2) has a lock release pin (22) protrudingly provided at a position facing the lock release pin hole (93) of the loaded tape cassette.

(Function) When loaded, the cassette tray (2) protrudes outward from the opening of the cabinet (Fig. 5a). When the cassette (9) is placed on the cassette tray, the lock release pin (22) is inserted into the cassette case. Lock release pin hole (9) formed in
3) and release the locking mechanism. When the cassette holder (3) is moved into the cabinet, the cassette tray is released from the cassette holder (3) at the end of the movement and is received by the lifting platform 5). By operating the lifting device, the cassette tray is lowered together with the lifting platform and is locked at a predetermined loading position.

The unloading operation is the reverse movement of the above.

(Implementation rIA) The cassette tray (2) has pins (20) (21) on both side walls.
The cassette holder (3) has vertical guide holes (30031) in its side walls, into which the pins (20) and (21) of the cassette tray are fitted so as to be movable up and down.

There are guide holes (30) (
Up plates (4) are slidably supported along guide pieces <33) corresponding to the upper end positions of 31), respectively. Slip board (
4), open the socket (42) toward the back, and insert the pin (2).
0) (21) is locked at the upper end of the guide hole (30>(31).The sliding plate (4) has a projecting piece (
40) (41>), a coiled spring f-(43) is provided using the protruding shaft (65) protruding from the side wall as a fulcrum, and one end of the coiled spring is attached to the protruding pieces (40) and (41) of the sliding plate. The other end is fixed to the protrusion (34) formed on the cassette holder, the sliding plate (4) is urged toward the guide holes (30) (31), and the pins (20) and (21) of the cassette tray are inserted into the sockets ( 42)/＼It is something that is removably locked.

A. A cassette holder (14) made of a spring is placed in the upper part of the opening of the yarn net (1). When the reel of the cassette (9) is tightly wound, the locking mechanism is firmly wedged into the uneven surface of the reel, so the release pin (22) does not release the lock, and the cassette (9) is held at one point in Figure 5. Although it is supported diagonally as shown by the chain line, even in this case, by pushing the cassette holder (3) into the cabinet, the cassette holder (14) presses the top surface of the cassette and releases the release pin (22) into the tape cassette. Entry can be made and the lock can be reliably unlocked.

The lifting platform (5) has a protruding shaft (54) (54) (54) on the side.
is provided protrudingly, and the vertical guide hole (
12) and can be moved up and down while maintaining a horizontal position. A presser piece (55) extending to the center of the cassette tray is provided on the top of the lifting platform (5), and a contact piece (55) is provided to match the height of the transition path of the protruding pieces (40) and (41) of the sliding plate (4). 50) (51).

Furthermore, the cassette tray pin (
20) In accordance with the transition height of (21), hook-shaped receiving pieces (52) and (53) which are open at the front of the cabinet are protruded, respectively.

An elevating plate (6) is provided on the side of the elevating table (5) so as to be able to slide up and down, and a spring (63) is placed between the protruding piece (62) formed at the lower end of the elevating plate and the protruding shaft (54) of the elevating table. ) is installed. The elevating plate (6) has vertical guide holes (60) and (61) formed therein, and guide shafts (60, 61) protruding from the elevating platform (5), respectively.
56), the protruding shaft <54), and attach the rack (6) to the side of the lifting plate.
4) and is engaged with the pinion (8).

When the cassette holder (3) is moved to the rear position of the cabinet (FIG. 5C), the pinion (8) rotates to lower the elevator plate (6). The lifting platform 5) is pulled by a spring (63) and moves downward, and the holding piece (55) moves down while pushing the cassette (9) on the cassette tray.

Even if the cassette presser (14) alone is insufficient to release the lock, the downward pressure on the cassette by the presser piece (55) ensures that the lock is released and the tape can be pulled out.

The present invention is not limited to the above description, and a person skilled in the art can easily change the structure within the scope of the claims to achieve the same purpose, and such design changes are not limited to the implementation of the present invention. This is to be understood as an example.
