Description

[Detailed explanation of the idea]

The present invention relates to simplifying the operation display mechanism in a cassette tape recorder having multiple mechanisms. Currently, in order to enable dubbing operations such as tape editing, continuous recording, playback operations, etc. with a single cassette tape recorder, there are models on the market that incorporate two sets of mechanisms to drive two cassette tapes at the same time. ing. In this cassette tape recorder, it is extremely important to let the operator know which mechanism is operating, or whether both mechanisms are operating, so a separate Provide indicators such as LED,
The operation of each mechanism will be displayed. However, this method requires a separate indicator, which complicates the configuration.
It also had drawbacks such as being time consuming to manufacture. The present invention eliminates the above-mentioned drawbacks by making use of a cassette tape illumination light to eliminate the need for an indicator, and will be described in detail below with reference to the accompanying drawings showing embodiments. FIG. 1 is a schematic view of the operating surface of a cassette tape recorder equipped with the operation display mechanism of the present invention, and FIG. 2 is an electrical wiring diagram showing the operation mechanism of the present invention. 1 is a power switch provided at a predetermined position on the operation panel 15; 2 and 3 are illumination lights that illuminate the cassette tape to display operation; 4 is a lamp for illuminating the VU meter; 5, 5... are operation buttons; 6, 6 ... is the operation knob, and the electrical connections are as follows. The power switch 1 and the primary winding of the transformer 8 are connected in series between both terminals of the commercial alternating power supply 7, and a full-wave rectifier 9 is connected between the secondary winding terminals of the transformer 8. A smoothing capacitor 10 is connected between the DC output terminals of the rectifier 9. Further, the lamp 4 is connected between both terminals of the full-wave rectifier 9.
and a switch 11 for detecting one of the cassette tapes between both terminals, and a switch 1 for detecting one of the cassette tapes and interlocking with a driving mechanism for one of the cassette tapes.
2 and the illuminating lamp 2 are connected in series, and the illuminating lamp 3 is also connected in series with a switch 13 for detecting the other cassette tape and a switch 14 interlocking with the mechanism for driving one cassette tape. The switches 12 and 14 can be closed at times other than when the machine is stopped, for example, by interlocking with the brake mechanism of the reel stand of each mechanism. The operation of the operation display mechanism configured as described above is as follows. When the power switch 1 is in the cutoff state, the illumination lights 2, 3 and the lamp 4 are all turned off, indicating a non-operating state. When the power switch 1 is turned on, the lamp 4 is immediately lit to indicate that the power is on. Next, when a cassette tape is set, one of the switches 11 and 13 is closed by the cassette tape. Therefore, by setting cassette tapes in both cassette tape storage sections, switch 1 can be set.
1 and 13 are closed together. In this state, since the switches 12 and 14 are both open, both the illumination lights 2 and 3 remain off, and the operation button 5 for performing operations such as fast forwarding, rewinding, recording, and playback must be operated. As a result, one or both of the switches 12 and 14 are closed, so that one or both of the lights 2 and 3 are turned on, thereby indicating which mechanism is operating. That is, when both switches connected in series are closed, the cassette tape is set and the mechanism is operating, so the illumination light is turned on.
It is possible to display the mechanism in operation. Moreover, at the same time, the remaining amount of tape can be easily known by the illumination light. Each switch 1 when switch 1 is closed
The relationship between turning on and turning off lights 1, 12, 13, and 14 and lighting lights 2 and 3 is shown in Table 1. Note that one cassette tape is referred to as cassette 1, the mechanism as mechanism 1, the other cassette tape as cassette 2, and the mechanism as mechanism 2.

【table】

[Table] In the embodiment shown in FIG.
2, 13, and 14 are used, but it is not necessarily necessary to use four switches, and as shown in FIG.
Even if you omit , it is possible to display which mechanism is operating. In addition, in the case of FIG. 2 or 3, if the pause lever (not shown) is operated during the recording/playback operation, the mechanism will be in a stopped state.
By connecting the lighting lamps 2 and 3 in series to 14,
can also serve as a display for pause operations, making it possible to eliminate the need for indicators for pause operations at all. As described above, the present invention makes it possible to display the operating mechanism by turning on and off the illumination light of the cassette tape, and also to know the remaining amount of tape. When the two states of starting recording and playback operations overlap, the corresponding illumination light is turned on, so you can operate the tape recorder without inserting a cassette tape, or simply insert a cassette tape. Simply inserting the cassette tape will not cause the illumination light to turn on. Therefore, when the light is on, it always indicates that one of the cassette tapes is in operation, so there is no risk of misidentification. Further, it is possible to completely eliminate the need for an indicator that has been required in the past, resulting in unique effects such as simplifying the structure, facilitating production, and reducing costs.
