Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device used for a tape recorder or the like that controls operation using electric means. 2. Description of the Related Art Generally, when operating and controlling a mechanism of a tape recorder using electric means, as shown in FIG.
Play, reverse, fast forward, rewind, stop operation switches 1
Input signals are input to the control circuit 2 from a, 1b, 1c, 1d, and 1e, and operation commands are issued according to a preset program to control the driving transistors 5, 6 of the plunger 3 and the motor 4. I was Problems to be Solved by the Invention However, in such operation control input means, it is necessary to provide a plurality of independent operation switches, which hinders the operability of the tape recorder when it is carried. Was. For this reason, in the conventional apparatus, only the playback and stop operation switches that are frequently operated during remote control are installed. However, it is difficult to reduce the size of the operation switch section while restricting the operation. there were. The present invention is to solve such a conventional problem, and to provide a remote control device that can increase the degree of freedom of arrangement and operation of operation switches, improve operability, and can be downsized. is there. Means for Solving the Problems A remote control device of the present invention generates a control circuit for controlling a plurality of operation states of a device main body and a pulse signal set in advance to perform a plurality of operation commands of the control circuit. One remote control button operation switch means for causing the control circuit to detect a pulse signal emitted from the one remote control button operation switch means and a current operation state from among a plurality of operation states of the device main body. And a control means for issuing an operation command corresponding to the number of times of the detected pulse signal and the current operation state of the device main body. The control means is provided by the one remote control button operation switch means. Even if the number of pulse signals is the same, a different operation command is issued in accordance with the detected current operation state of the device The operation state is controlled by the one remote control button operation switch means. The remote control device of the present invention improves the operability when carrying by controlling the operation in accordance with the number of pulse signals emitted from one button operation switch and in accordance with the current operation state of the device. The operation switches can be arranged as desired, and the position of the operation switches can be easily confirmed corresponding to various operations. Further, since this one button operation switch is provided separately from the apparatus main body as a remote control switch, and a plurality of operations are performed by a single operation switch, the configuration can be made small and lightweight. Embodiment Hereinafter, a case where a remote controller according to an embodiment of the present invention is used for a tape recorder will be described with reference to the drawings. As shown in FIG. 1, operation switches 1a, 1b, 1c, 1d, 1e for reproduction, inversion, fast forward, rewind, and stop, and a control circuit 2
And a single remote control button operation switch 9 connected to the cyclic input terminal. When the control input command is input to the control circuit 2 by turning on the button operation switch 9, if the mechanism when the button operation switch 9 is turned on is stopped as shown in the flowchart of FIG. When ON is turned on, a mechanism operation command is output so that the mechanism changes its state to rewind, and if not turned on, to rewind. If the mechanism at the time when the button operation switch 9 is turned on is in the reproduction state, the button operation switch 9 is turned on again to reverse, if not turned off, to stop.
If the mechanism when the button operation switch 9 is turned on is neither stop nor reproduction, a mechanism operation command is output to change the state of the mechanism to fast-forward.
In other words, even if the number of pulses is the same due to the operation of the button operation switch 9, different operation commands can be output according to the current operation state of the device. As described above, in the functional operation of the control circuit 2, a step of detecting the operating state of the mechanism when one button operation switch 9 is turned on, and a step of detecting the number of pulses that is the number of times the button operation switch 9 is turned on. Play, flip, fast forward,
The mechanism can be switched to the next state step with a single operation switch by outputting each of the rewind and stop operation commands corresponding to the current operation state of the mechanism and the number of detection pulses. The one button operation switch 9 is, as shown in FIG. 3, a headphone cord for connecting the headphone 10 and the main body 11.
Even when the main body 11 is provided in the middle of the case 12 and stored in a bag or the like, a plurality of operation commands can be input as a remote control with a single operation switch. Effect of the Invention As described above, the remote control device of the present invention detects the number of pulses input by one remote control button operation switch means and the current operation state of the device, and corresponds to the detected operation state and pulse number of the device. Thus, a plurality of operation commands are output, and a small and lightweight operation unit can be realized, which is very useful for improving operability. In particular, even if the number of pulses is the same due to the operation of one remote control button operation switch means, a plurality of operations can be performed according to the current operation state of the device, so that the restriction on the operation function can be greatly eased. This is extremely advantageous in practical use.
