Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a remote control device for remotely controlling electronic devices such as microfilm readers and printers.

(Prior Art) Recently, in order to improve the operability of the above-mentioned microfilm reader/printer, one that can be operated from a remote location using a remote control device is being developed. That is, a control signal is transmitted from a transmitter equipped with a remote control device, the control signal is received by a receiver installed in a controlled device such as a microfilm reader/printer, and the microfilm reader/printer is remotely controlled. is configured to do so. Thus, a control signal is transmitted from a transmitter, and the control signal is received by a receiver to search for a desired frame on the microfilm or to print an image of the desired frame.

At this time, the frame number of the searched microfilm, the number of pages of the file, the number of prints, etc. are displayed on the display section of the main body of the reader printer.

That is, the conventional remote control device operates the keyboard 107 of the transmitter 101 to control the transmitter 108, as shown in FIG.
The microfilm reader/printer 102 is configured to output a control signal made of infrared rays or the like from the microfilm reader/printer 102 and to remotely control microfilm searching and printing. The receiving unit 109 that receives the control signal includes the microfilm reader printer 10
2 is provided near the operation section 110 of the receiving section 1.
The control signal received at 09 controls the microfilm reader/printer via a receiver (not shown).

(Problems to be Solved by the Invention) However, in the case of such prior art, the receiving unit 10
9 is fixedly attached near the operating section 110 of the microfilm reader/printer 102, the receivable range of the control signal is determined within a predetermined range depending on the capability of the receiving element in the receiving section 109 or the transmitting element 108. As a result, the range in which the operator transmits the control signal from the transmitter 101 is narrowed, and if the control signal is transmitted from other locations, the control signal from the transmitter 101 is so small that it cannot be accurately transmitted by the receiver. There was a problem in that the system was not identified and the device became inoperable.

Furthermore, in the case of such conventional technology, the transmitter 101 allows the microfilm reader/printer 102 to be operated from a remote location, which improves operability; Since it is provided in the microfilm reader/printer 102, it is difficult to visually observe it from the operating position. Therefore, each time you perform an operation using the transmitter 101, or when a series of operations is completed, you must go to the microfilm reader printer 102 and visually check the display section to check whether the specified operation is being performed. Not only is this extremely troublesome, but it also has the major problem of halving the operability of the remote control device.

Therefore, the present invention has been made to solve the above-mentioned problems of the conventional example, and its purpose is to significantly expand the range of use of the transmitter by the operator, and to improve the operating status of the controlled device. An object of the present invention is to provide a remote control device whose operability is dramatically improved by making the display section movable.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a control signal is transmitted from a transmitter, and the control signal is received by a receiver provided in a controlled device. In the remote control device for remotely controlling the controlled device, an operating state display signal transmitting means is provided for transmitting a signal for displaying the operating state to the controlled device, and the remote control device is configured to receive the operating state display signal. The transmitter is provided with a display means for displaying the operating state of the controlled device, and the directions of both the receiver and the operating state display signal transmitting means are controllable based on the control signal. ing.

(Function) In the present invention having the above configuration, the transmitter is provided with a display means for receiving a signal from the operating state display signal sending means provided in the controlled device and displaying the operating state of the controlled device. This expands the scope of use of the transmitter by ensuring reliable display with the transmitter at hand and by making it possible to control the direction of the receiver and the operating status display signal sending means based on the control signal from the transmitter. It is.

(Example) The present invention will be explained below based on the illustrated example. 1st
The figure is a perspective view showing an example in which the remote control device according to the present invention is applied to a microfilm reader/printer. In the figure, 1 is a search machine body as a controlled device, and 2 is a screen for displaying microfilm images. , 3 is a part of the printer, 4 is a microfilm search unit, 5 is a movable receiving unit for infrared rays (operation signals), and 6 is an operating state display signal transmitting means installed in parallel with the movable receiving unit 5 in the search machine body 1. The transmitting section 6 transmits an information signal for displaying the operating state of the search machine main body l. 7 is a transmitter for remote control;
Reference numeral 8 denotes the above-mentioned information signal power receiving section in the transmitter 7, and 9 is a display means provided in the transmitter 7 for receiving the information signal from the transmitting section 6 at the receiving section 8 and displaying the operating state of the search device main body 1. .

3 is a block diagram of a transmitter in the present invention, and FIG. 4 is a block diagram of a receiver in the same embodiment. In FIG. 3, 11 is a keyboard for inputting control commands;
12 is an encoder that encodes the signal from the keyboard 11, 13 is a modulator, 14 is a carrier generator, and 15 is a transmitter that emits infrared light. In Figure 4, 22
is a register, 23 is a decoder, and 24 is a microcomputer. In these configurations, when the keyboard 11 of the transmitter 7 is pressed, the control command signal enters the encoder 12 and is pulsed, at which time the check code stored in memory is also encoded by the encoder 12 and sent to the carrier generator 14. A modulator 13 modulates the carrier signal from the transmitter 13, and the transmitter 15 transmits the modulated signal as an infrared signal. On the other hand, the receiver receives an infrared signal from the transmitting section 15 using the movable receiving section 5, inputs it to the register 22, and inputs the infrared signal from the transmitting section 15 to the decoder 2.
The control signal whose code has been determined in step 3 and the check code are input to the microcomputer 24. This microcomputer 24 operates a search unit 4 in the search machine main body l, which is a controlled bag, in accordance with the code-discriminated control signal.
and drives the printer part 3. As a result, information signals such as the searched film number, number of prints, and error check signal are modulated by infrared rays by the CPU 60 and sent to the transmitter 6.
The signal is transmitted by the receiver 8 of the transmitter 7 and is received by the receiver 8 of the transmitter 7, and the operating state of the search machine main body 1 is displayed on the display 9 based on the signal.

Next, FIG. 2 is a block diagram showing the direction control system of the movable receiving section 5 in the remote control device according to the present invention. Converter, 32 is a CPU for controlling the receiving unit drive motor, 33 is a D/A converter that converts the output signal from the CPU 32 into analog, 34 is a forward/reverse control circuit, 35 is a DC servo motor for driving the receiving unit, 36 is an encoder ,
37 is a position detection circuit, and 60 is a CPU connected to the transmitting section 6 and modulating the information signal. And 22.23.24
As shown in FIG. 4, these are a register, a decoder, and a microcomputer, and this microcomputer 24 outputs operation signals.

Further, in the above configuration, the operation of the direction control system of the movable receiver 5 will be explained based on the flow and yard diagrams in FIG. First, when an infrared signal from the transmitter 15 is input to the movable receiver 5, the microcomputer 24 outputs a corresponding operation signal via the register 22 and decoder 23. On the other hand, the infrared signal is digitally converted by the A/D converter 31 and input to the CPU 32 (step ■).
This CPU 32 indicates the current position of the DC servo motor 35,
That is, since the direction in which the movable receiver 5 is facing is memorized, when a signal is input, it outputs a speed signal that drives the DC servo motor 35 in a certain direction by a minute angle, and the D/A converter 33 controls forward/reverse rotation. When the DC servo motor 35 is driven through the circuit 34 (step ■), the direction of the movable receiver 5 changes and the magnitude of the incident signal changes, so the amount of change in the signal voltage (signal voltage differential value) is detected. be done (
Step ■).

That is, in step (2), since the position at which the signal voltage increases is in the current direction of rotation of the DC servo motor 35, that is, the movable receiver 5, the DC servo motor 35 is activated to output a signal that maintains the current direction of rotation. Rotate forward (step ■
-a), and since the movable receiver 5 is considered to be facing in the direction of the signal, the rotation of the DC servo motor 35 is stopped (step -b).Furthermore, the signal voltage may decrease. Since the signal voltage only decreases, a signal is output to reverse the rotation of the DC servo motor 35, so that the movable receiver 5 faces in the direction where the signal is maximum (step 3-c)0 The above procedure is repeated, and when the movable receiver 5 faces the direction in which the signal with the maximum intensity can be obtained, the drive of the DC servo motor 35 is stopped and the next input signal is waited for, that is, step ■-a and step ■ -C returns to step ■ (■), the above procedure is repeated, and step ■
At -, the drive of the DC servo motor 35 is stopped and the next input signal is waited for (■).

Here, in FIG. 2, the position detection circuit 37 feeds back the current speed and position of the DC servo motor 35 to the D/A converter 33 and CPU 32, respectively, based on a signal from the encoder 36 that is synchronized with the DC servo motor 35. Therefore, in order to prevent the movable receiving unit 5 from heading out of the effective drive range, the speed of the DC servo motor 35 is decreased as it approaches the direction of maximum signal incidence, and gradually decreases as it approaches one drive angle. By doing so, the receiving section 5 is made to face the target direction and stop as quickly as possible.

In the above embodiment, D is a signal that is input continuously to some extent.
By driving the C servo motor 35, it is possible to easily distinguish between noise and signals, and to eliminate malfunctions caused by noise.

Further, as shown in FIG. 2, since the movable receiving section 5 and the transmitting section 6 that transmits the information signal to the transmitter 7 are arranged side by side facing in the same direction, the display modulated by the CPU 60 is The information signal is transmitted by sending infrared rays from the transmitting section 6 to the receiving section 8 at the optimum position, and the information is thereby displayed on the display section 9.

That is, the transmitting section 6 is arranged in parallel with the movable receiving section 5, and together with the movable receiving section 5, the transmitting section 6 is driven by a coaxial motor so that its direction is controlled based on the control signal from the transmitter 7. It has become.

Here, if the movable receiving section for the control signal and the transmitting section for the information signal are controlled so that they always face the same direction, there is no need to arrange them in parallel on the same shaft motor.

Incidentally, in the above embodiment, the receiving section 5
is directed by the DC servo motor 35, but the present invention is not limited to this, and the combination of the receiving section and the transmitting section is not limited to this, and a plurality of receiving sections and transmitting sections are directed in different directions, and the receiving section and the transmitting section receive the largest signal depending on the direction in which the signal is received. You may also adopt a means of selecting.

This further expands the receivable range.

In addition, in the above embodiment, one DC servo motor was driven and the direction of the maximum signal of the receiving section was scanned in the horizontal plane, but x
- It may be configured to include a two-axis drive unit orthogonal to the Y axis or a drive unit with multiple axes or more to scan the maximum signal direction three-dimensionally (three-dimensionally). This means that the receivable range in the horizontal direction will be expanded.

Furthermore, instead of making the receiving element movable as in this embodiment, an optical system such as a lens or mirror that can change the direction of the communication medium (infrared rays) is provided in front of the receiving element, and the optical system is It may also be driven.

Yet again. In the above embodiment, a case has been described in which an infrared signal is used as a signal to be transmitted, but it goes without saying that ultrasonic waves, electromagnetic waves, etc. may also be used.

Further, in the above embodiment, the CPU is 24.32.

60 are separate units, but all or any two of them may be the same CPU.

In addition, the present invention is not limited to the driving method described in the above embodiment as long as the speed and position can be controlled.

(Effects of the Invention) The remote control device according to the present invention has the above-described configuration and operation, and can receive even undiscernible input signals by pointing the receiver in a discriminable direction. It becomes possible to significantly expand the operable range of the transmitter. Therefore, the control signal from the transmitter reliably reaches the receiver, improving reliability. Further, the operating state display signal can be transmitted at the position where it is loudest, and erroneous display due to noise can be prevented. Furthermore, since the display means for displaying the operating state of the controlled device is made movable, when the controlled device is remotely controlled from this position, the operating state of the controlled device can be checked from the display means at source L. is possible,
It is no longer necessary to go all the way to the controlled device to check the operating status of the controlled device after sending the control signal from the transmitter as in the past, dramatically improving the operability of the remote control device. This effect is achieved.
