Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording/reproducing apparatus, particularly a slot-in type magnetic recording/reproducing apparatus.

Conventionally, a slot-in type magnetic recording/reproducing apparatus, as shown in FIG. 1
The cassette 3 is inserted into the cassette 3 and loaded into a predetermined position by a cassette loading mechanism (not shown). This type of magnetic recording/reproducing device has the disadvantage that the remaining amount of cassette tape 3, the rotation of the reel, etc. cannot be seen directly from outside the casing because the cassette 3 is loaded inside the casing during recording/playback. Ta. Generally, two to three proposals have been made to solve these drawbacks, but none of them has been satisfactory.

The present invention aims to eliminate these drawbacks, and proposes a magnetic recording/reproducing device that has a simple structure and allows the remaining amount of tape in a cassette loaded in the device housing to be accurately viewed.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.

Fig. 2 is an external perspective view of a magnetic recording and reproducing device that is an embodiment of the present invention, Fig. 3 is an explanatory diagram of the operation of the device, Fig. 4 is a top view of the main parts of the device, and Fig. 5 is the same device. FIG. 2 is a main part electric circuit diagram.

In the figure, 1 is the casing of the main body of the device, 2 is a cassette insertion opening (slot) provided in the casing 1, 3 is a cassette containing a magnetic tape, and 4 is a translucent slot provided on the top of the casing 1. A window consisting of a panel, 5 a cassette holder for moving the tape cassette 3 inserted from the slot 2 to a specified tape operating position by a cassette loading mechanism (not shown), and 6 a scale on the surface to indicate the remaining amount of tape. a movable scale plate 7 that is displayed and moves around a fulcrum 6a by the movement of 5;
is a lighting switch that is turned on when the cassette holder 5 is loaded in the tape operating position; 8 and 9 are light sources (lamps) that are lit by the switch 7; and 10 is a power source for lighting the lamps 8 and 9. Department.

Next, the operation of this device will be explained.

When the cassette 3 is not loaded, the cassette holder 5 is at position A, so the movable scale plate 6 is positioned parallel to the window 4 with its end 6c in contact with the tip 5a of the cassette holder 5. There is. When cassette 3 is inserted from slot 2 in this state, it is loaded into cassette holder 5 and moved to position A by the loading mechanism.
Parallel movement from to position B. At this time, the end portion 6c of the movable scale plate 6 is connected to the cassette holder 5 from the tip 5a.
As the cassette holder 5 moves, it slides to the terminal end 5b, and as the cassette holder 5 descends from position B to position C, the movable scale plate 6 rotates around the fulcrum 6a from position 6c to position 6b, and the cassette holder 5 is installed at position C. Then, the rotation of the movable scale plate 6 stops while maintaining a constant angle. At this time, the switch 7 is turned on, and the two light sources 8 and 9 provided on the upper left and right sides of the cassette holder 5 are turned on, illuminating the upper part of the cassette 3 and the surface of the movable scale plate 6. Next, when the eject button (not shown) provided at the front of the housing 1 is pressed, the cassette holder 5 moves in the opposite direction to the loading time, and exits the slot 2 via position C → position B → position A. Guide cassette 3. In this manner, in this embodiment, the cassette 3 and movable scale plate 6 inside the housing 1 can be directly viewed from the outside, that is, from the upper front side of the housing 1 through the window 4, so that the remaining amount of tape and the operating status of the tape can be viewed directly. You can also check the presence or absence of a cassette, the contents of the label attached to the cassette, etc. Therefore, it is useful for early detection of abnormalities related to tape running. Moreover, since the movable scale plate 6 serves to prevent the internal mechanism (not shown) from being seen through the window 4 from the outside of the housing 1 at the position 6c, the aesthetic appearance is not impaired.

As described above, according to the present invention, by disposing a light-transmitting member on the top of the housing so that the cassette loaded in the housing and the movable scale plate can be seen, the window can be viewed from the outside, that is, from above the housing. Through this, the magnetic tape stored and wound in the cassette and the movable scale plate can be directly viewed, and the running state of the tape and the remaining amount of tape can be read numerically.
