Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette tape recorder in which it is possible to directly determine whether the tape is running based on the rotation of the reel shaft.

In a cassette type tape recorder, since the tape is stored in a cassette case, it is very difficult to determine whether the tape is being played or not. For this reason, conventional methods have been to provide a pattern on the tip of the reel shaft so that it can be determined that the tape is running by changing the pattern as it rotates, and to send an optical chopper from the reel shaft via a belt, etc. It has been proposed that the tape recorder is rotated so that a light band or the like is projected onto the front of the case of the tape recorder by this optical chip, so that it can be determined whether the tape is running by the movement of the light band or the like. .

However, the former method is completely ineffective because the pattern cannot be distinguished when a tape recorder is used in a dark place, and the latter method is expensive due to the large number of parts, and at the same time it is difficult to use optical chips. This requires a space and a space on the front of the case for projecting the light band, etc., making the device large and extremely uneconomical.

The present invention is intended to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

1 is a cassette type tape recorder main body, and a cassette 2 is attached to the front of the main body 1 by a holder 5 having a lid 4 formed of a transparent plate and including two hubs 3 of the cassette 2. There is.

When the cassette 2 is attached to the main body 1, a claw 6 provided on the main body 1 is attached to the hub 3 of the cassette 2.
A hub drive body 7 made of a non-transparent resin of black color or the like is fitted into each hub drive body 7, and the fitting portion is configured to be visible from the front of the main body 1 through the lid 4. ing.

The hub driving body 7 is biased upwardly by a spring 11 at the upper end of a shaft portion 10 of a translucent reel stand pulley 9 made of milky white resin or the like and rotatably supported by a base plate 8. When the reel stand pulley 9 is rotated by an idler (not shown) or the like from a drive source, the hub drive body 7 also rotates, and its pawl 6 engages with the protrusion 3a of the hub 3. At the same time, the hub 3 is rotated and the tape 12 is run. Reference numeral 13 denotes a lamp attached at an angle 14 to the base plate 8 between the two reel stand pulleys 9, and the light of this lamp 13 illuminates each of the reel stand pulleys 9, so that the reel stand pulley 9 is connected to the lamp. 13 and the back of the decorative board 15 as a reflecting plate, the decorative board 15 shines brightly due to the light reflected by this reflecting plate, and it is the decorative board 1 through which the shaft part 10 of the reel stand pulley 9 is inserted.
It can be seen brightly from the outside of the main body 1 through the gap between the hole 16 of No. 5 and the shaft portion 10, and also through the gap between the hub 3 and the hub drive body 7. As a result, since the hub drive body 7 is non-transparent, it is clearly visible against the background of the brightly illuminated reel stand pulley 9, and therefore, from the front of the main body 1, the hub drive body 9 is in a rotating state together with the hub 3. It is possible to clearly determine whether the tape is running or stopped, and the running state of the tape can be easily determined.

As described above, according to the present invention, the left and right reel stand pulleys made of a translucent material are illuminated by a light source placed between them, and the illuminated reel stand pulleys are made of an opaque material. The hub drive body, which is made of an opaque material and has claws around the periphery, is located in the center of the illuminated reel stand pulley. The rotating status of the reel stand can be clearly determined, and the running status of the tape can also be easily checked even when used in a dark place. In addition, the back of the decorative board that hides the back of the cassette is used as a reflector, and the light reflected by this reflector illuminates the reel stand pulley, so a small light source can be used, making the cassette-type tape recorder more compact. There is no obstacle to making the device thinner. In addition, by using the back of the decorative board located below the cassette as a reflector, the reel stand pulley provided for running the tape can be made of a translucent material without changing its shape. It is extremely economical, as it only requires a light source, and since it utilizes the gap between the hub drive body and the hub, there is no need for any other parts or space on the front of the case. Yes, and the effect is great.

Claims (1)

[Scope of utility model registration request] A hub formed of a non-transparent material and having a light source that illuminates the reel stand pulley between two left and right reel stand pulleys formed of a translucent material, and rotatable integrally with the reel stand pulley. Direct light from the light source is transmitted from the outside through the gap between the hub of the cassette that engages with the drive body and the hub drive body, and the cassette is illuminated around the rotation axis of the reel stand pulley provided between the light source and the cassette. A cassette type tape recorder comprising a decorative plate having a hole of approximately the same size as the hub hole, with a reflective plate on the back side, and the reel stand pulley illuminated by the light reflected by the reflective plate appears bright. .
