Description

[Detailed Description of the Invention] The present invention relates to a magnetic recording and reproducing device that pulls out a magnetic tape from a tape cassette using a tape pull-out pin and winds the magnetic tape at a predetermined angle around a head cylinder containing a rotating head. The magnetic tape is stably guided to a limiter post which is fixed to the device and restricts the running position of the running magnetic tape. When a tape cassette is installed in the device, the magnetic tape stored in the cassette case may be damaged by the impact of the cassette immediately after the cassette is installed.
Due to the tape's automatic action, the tape becomes slack in the cassette, and the lower end of the tape touches the cassette case from the normal running position shown in Figure 1 A and B to the state shown in Figure 2 A and B. It may become.

In FIGS. 1 and 2, 1 is a cassette case, 2 is an opening in which a tape pull-out pin is inserted, and a magnetic tape 3 exposed on the front surface of the cassette case 1 is inserted into an opening provided on the front surface of the case; 4a
is the tape guide post inside the cassette case. If the tape is pulled out using the tape pull-out pin from the state shown in FIG. This caused damage to the magnetic tape. The present invention aims to solve this problem, and one embodiment thereof will be described below with reference to the drawings.

In FIG. 3, reference numeral 1 denotes a tape cassette containing a supply reel 5 and a take-up reel 6, and an opening 3 provided on the front surface of the tape cassette when installed.
Tape pull-out pins 7a and 7b respectively inserted into
, 7c and 7d move in the direction of the dashed line to wind the magnetic tape around the head cylinder 8 at a predetermined angle. Note that 9 is an erase head, 10, 11
is a limiter post, 12 is a tension post, 1
3 is an impedance roller, 14 is a head for audio/control signals, 15 is a pinch roller, 16
is Capstan.

The above configuration is the same as this type of magnetic recording/reproducing device.

As clearly shown in FIGS. 4 and 5, the feature of the present invention is that a limiter post 18 having a sufficiently large flange 17 for regulating the tape position at the lower end is attached to a rotating arm 19 about a support shaft 20. It is rotatably provided in the device and is configured to be located at the opening of the tape cassette as shown in FIG. 3 when the cassette is installed. The flange portion 17 of the limiter post 18 is connected to the fixed limiter post 11.
It is configured to be located approximately on the same plane as the lower regulating step.

In the above configuration, the rotating arm 19 is rotated to the position 19a in FIG. 3 as the tape is pulled out, and the magnetic tape is also held by the collar 17 and pulled out with this rotation. It is securely attached to the lower regulating step of the fixed limiter post 11. When the tape drawing operation is completed, the traveling position of the tape is restricted by the fixed limiter post 11, so the collar 17 plays an auxiliary role. Incidentally, if the vicinity of the lower part of the fixed limiter post 11 is formed into a tapered shape as shown in FIG. 5, the magnetic tape can be attached to the limiter post 11 smoothly.

As described above, according to the present invention, it is possible to prevent the magnetic tape from being damaged during tape loading due to the tape falling when the cassette is installed.
