Abstract

PURPOSE:To attain the miniaturization by driving a reel base elevated with a cassette holder after the cassette holder rises so as to wind a magnetic tape at the cassette front aperture. CONSTITUTION:As the cassette holder 5 rises, a connection arm 11-a supported pivotally and turnably to the cassette holder 5 is driven around a shaft 11-c, a transmission gear 12 provided coaxially with the connection arm 11-a is driven in the direction of arrow B and a reel base vibrating member 13 engaged with the transmission gear 12 is moved in the direction of arrow C. A reel base 6-b has a structure freely turnably on the cassette holder 5 and is engaged with a reel hub by a claw 6-a to drive a magnetic tape 3 in a cassette 2. When the reel base drive part 13 is moved in the direction of arrow C attended with the elevation of the cassette holder 5, the reel base 6-b is driven in the direction of arrow D on the cassette holder 5 to wind up a magnetic tape 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording/reproducing device, and particularly to a cassette holding device suitable for downsizing the device.

[Conventional technology]

Conventionally, in magnetic recording and reproducing devices, a tape winding method using a reel stand when loading/unloading a cassette has been described in Japanese Patent Application Laid-open No. 5'9.
- There is a method described in No. 1'71070 etc.
According to this method, it is difficult to wind up the tape on the front of the cassette with the reel stand when the rotary cylinder is stored in the opening on the front of the cassette, and even when the cassette is attached or detached, the length from front to back of the device is limited. It was impossible to make the cassette smaller than the sum of the length of the cassette and the diameter of the cylinder.

Problems that CgS Ro is trying to solve] In other words, the above-mentioned conventional technology stores a rotating cylinder in the opening on the front of the cassette, and uses a raising device to drive the reel stand for the magnetic tape stretched over the cassette opening. No consideration has been given to the winding method, and if the length of the front and back of the device is greater than the sum of the vertical length of the cassette and the diameter of the cylinder, the cassette can be slid back and forth, and the rotating cylinder can be rolled into the cassette. After moving outside the opening, drive the reel stand,
Since the magnetic tape at the cassette opening L1 is wound up, there is a problem in that the front and back length of the device increases when the cassette is attached or detached.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic recording/reproducing apparatus which can solve the above two problems and realize a smaller size of the magnetic recording/reproducing apparatus.

[Failure to solve the problem]

The above purpose is to move the cassette upward from the position where the rotary cylinder is stored in the cassette opening part when attaching or removing the cassette, and to reach the height position where the rotary cylinder has come out of the cassette opening.
This is achieved by driving the reel stand that has been raised together with the cassette by a moving operation that raises the cassette 1-, and winding up the tape at the opening of the cassette.

[Effect]

The reel stand that drives the reel hub inside the cassette and winds the magnetic tape is mounted on the cassette box, and as the cassette box rises, the arm that connects the cassette box and chassis moves against the cassette box. By transmitting the amount of rotation to the reel stand on the cassette box through the teeth t, the reel stand is rotated as the cassette box rises, and the tape at the cassette opening is wound up.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIGS. 2 and 3 are plan views showing an outline of the magnetic recording/reproducing apparatus according to the present invention.

1 is the chassis, 2 is the cassette, and 3 is the magnetic tape.

4 is a reel wound with magnetic tape 3 in cassette 2;
is a cassette holder that holds the cassette 2 against the chassis 1; 6 is a reel stand installed on the cassette holder 5 and drives the reel 4; 7 is a rotary cylinder on which a magnetic head is mounted; 8 is a rotating cylinder on which a guide roller is mounted. A guide base pulls out the magnetic tape 3 from the opening 2-a of the cassette 2 and winds it around the rotary cylinder 2 at a predetermined angle; 9 and 10 are a capstan and a pinch roller that drive the magnetic tape 3;

11 is a connection arm that connects the chassis 1 and the cassette holder 5; 12 is a transmission gear that is coaxially supported with the connection arm 2 on the cassette holder 5 and transmits the rotation of the connection arm 12; 13 is a transmission gear; This is a reel stand driving member that drives the reel stand 6 by rotation of the reel stand.

When taking out the cassette 2 from the magnetic recording/reproducing apparatus, move the guide base 8 to the opening 2-a of the cassette 2 as shown in FIG. Rotate in direction E to wind up.

FIG. 1 is a side view of a magnetic recording and reproducing device according to the present invention, and
FIG. 4 is a perspective view of the reel stand portion.

Parts that correspond to the previous one have the same numbers.

As shown in FIG. 1, when taking out the cassette 2 from the magnetic recording/reproducing apparatus, move the cassette holder 5 upward y1 in the direction of arrow A, let the rotary cylinder 7 escape from the opening 2-a of the cassette 2, and 2-a. 4. After winding up the slack magnetic tape 2 inside, the lid 2-b of the cassette 2 is closed.

As the cassette holder 5 rises, the connection arm 11-a rotatably supported by the cassette holder 5 rotates around the shaft 11-c, causing the transmission gear 12 provided coaxially with the connection arm 11-a to move as shown in the arrow. The reel stand vibration member 13 rotates in the B direction and is further engaged with the transmission gear 12, moving in the arrow C direction.

The reel stand 6-b has a structure that allows it to rotate freely on the cassette holder 5, and the reel hub 4-b is supported by the Clara part 6-a.
a to drive the magnetic tape 3 in the cassette 2. Therefore, as shown in FIG.
3 moves in the direction of arrow C as the cassette holder 5 rises, the reel stand 6-b rotates in the direction of the arrow C on the cassette holder 5, making it possible to wind up the magnetic tape 3.

With the above-described mechanism, according to this embodiment, the reel stand 6-b on the cassette holder 5 is driven by the upward movement of the cassette holder 5 and the magnetic tape 3 is wound. The rotating cylinder 7 can be stored in and removed from the cassette opening 2-a without requiring a sliding mechanism of the chassis, and the magnetic recording/reproducing device can be downsized with a simple mechanism, including when the cassette is attached. be.

〔Effect of the invention〕

As described above, according to the present invention, after the cassette holder is raised, the cassette! - The mechanism drives the reel stand that rises with the holder and winds up the magnetic tape from cassette 1 to the front opening, so when using a cassette device, when the rotary cylinder is stored in the cassette opening to reduce the size of the device, There is no need to slide the cassette in the direction of a rotating cylinder to attach or detach the cassette, and the length of the device in the vertical direction does not increase when the cassette is attached or detached, and the device can be downsized with a simple mechanism.
