Description

[Detailed description of the invention] The present invention provides a light emitting element directly connected to the reel motor drive circuit on the head of the reel stand rotated by the reel motor, and the light emitting element blinks or lights up depending on the playback mode or fast forward mode. The present invention relates to a rotation display device that displays the rotation state of a reel motor in a manner that causes the reel motor to rotate.

Generally, a three-motor tape recorder has a supply reel motor, a take-up reel motor, and a capstan motor. During playback, the take-up reel motor and capstan motor are rotated, and during fast forwarding, the take-up reel motor and capstan motor are rotated. The side reel motor is rotationally driven, and the supply side reel motor is rotationally driven during rewinding.

In this way, the take-up reel motor and the supply reel motor are selectively driven to rotate depending on the fast-forward mode or the rewind mode, and in particular, the rotation speed of the take-up reel motor is switched depending on the fast-forward mode or playback (recording) mode. In this way, the governor circuit is inserted into and removed from the motor circuit.

As mentioned above, the present invention indicates the rotational state of the reel motor by lighting a light emitting element provided on the reel protrusion,
When the light-emitting element on the take-up side reel rise part is lit, the user can be notified that the fast-forward mode is in effect.
Particularly in the playback (recording) mode, the light emitting elements are made to blink by the action of the governor circuit.

The apparatus of the present invention shown in the drawings will be explained below.

FIG. 1 shows a front view of a tape deck in which the device of the present invention is implemented, and is equipped with a playback button 1, a fast-forward button 2, a take-up button 3, etc., and when the playback button 1 is operated, the capstan motor and the take-up reel motor are activated. The reel motor rotates to enter the playback mode, the take-up reel motor rotates to enter the fast-forward mode by operating the fast-forward button 2, and the supply-side reel motor rotates to enter the rewind mode by operating the rewind button 3.

Light-emitting elements 6 and 7 made of light-emitting diodes are provided at the head of the take-up reel stand 4 and the head of the supply reel stand 5, respectively, and these are connected to the transparent window 9 of the cassette holder 8.
It can be monitored from

FIG. 2 shows the arrangement of a take-up reel motor 10 equipped with a take-up reel stand 4 and a supply reel motor 11 equipped with a supply reel stand 5. As described above, the light emitting elements 6.7 are provided.

FIG. 3 shows a circuit diagram of the take-up reel motor 10,
During fast forwarding, the switch 12 is switched to the terminal A side to rotate the reel motor 10, so a light emitting element 6 consisting of a light emitting diode is connected in parallel to both ends of the motor 10 via a current adjustment resistor 13. The light emitting element 6 lights up with the rotation of 10.

Further, during reproduction, the switch 12 is switched to the terminal B side and the motor 10 is rotated through the governor circuit 14.

During this regeneration, the governor circuit 14 operates and the motor 10 rotates at a low speed.
An intermittent current flows due to the on/off operation of the switch, resulting in a blinking state.

FIG. 4 shows the configuration of the motor 10, which is configured so that a light emitting element 6 provided at the head of the reel stand 4 is supplied with power through a slip ring 15 and a brush 16.

In the figure, 17 is a motor shaft, and 18 is an insulating ring.

Since the device of the present invention is configured as described above, the fast-forward mode can be displayed by rotating the take-up reel motor 10 and lighting up the light emitting element 6 provided on the reel protrusion. Also, the playback mode can be displayed by blinking the light emitting element 6 provided on the reel protrusion.

As described above, according to the device of the present invention, when voltage is applied to the motor, the light-emitting element dynamically lights up or blinks, so the fast-forward mode or playback mode can be easily confirmed from the outside depending on the light-emitting state of the light-emitting element. Since this light emitting element is directly connected to the motor circuit, it is also useful for monitoring motor malfunction.

The lighting of the light emitting element also has a decorative effect on the cassette mounting portion, and is of high practical value.
