When a reception section 19 of a receiver 7 provided to the printer part 5 receives an infrared ray signal from the transmitter 1, the code of the reception signal is discriminated to drive a printer control circuit and the desired frame is printed by the printer part 5.

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) Conventionally, in the above-mentioned microfilm reader/printer, etc., as shown in FIG. 6, a carrier section 30. A screen 31 for projecting the image of the microfilm. A printer unit 32 that copies the projected microfilm image. and a keyboard section 33 for operating these sections, and each section is connected to the keyboard section 33 via a cable 34.

When the keyboard section 33 is operated, the printer CPU circuit 3 is connected to the printer CPU circuit 3 via the cable 34, as shown in FIG.
5, the code corresponding to the key of the keyboard section 33 is sent, the printer CPU circuit 35 reads this, and if the code is a print command, drives the print control circuit 36 to operate the printer section, Copy the projected microfilm image. Further, if the sent coat is a carrier operation command, the printer CPU circuit 35
A command code is sent to the carrier CPU circuit 37, and the carrier CPU circuit 37 reads this command, drives the carrier control circuit, operates the carrier 130, moves the target frame of the microfilm to the projection position, and displays the frame. is projected onto the screen 31.

(Problems to be Solved by the Invention) However, in the case of such prior art, as shown in FIG. 7, the keyboard section 33. Printer CPU circuit 3
5. Since the three carrier CPU circuits 37 are connected to each other by cables, for example, the printer CPU circuit 3
5 and the carrier CPU circuit 37 are required both in terms of heart and software, and the two functions of the printing machine 1 finger and the film carrier machine moat are modified,
It was not easy to change the design to a new circuit. Furthermore, even after one assembly, when replacing the printer unit 32 with another device, the cable 34 must be removed and reconnected, making the replacement work very complicated. Further, there are problems in that the thick cable 34 to which the keyboard section 33 is connected is exposed, deteriorating the appearance or operability, and making the cable 34 more susceptible to external noise.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and its purpose is to eliminate the need to connect the electronic components of each part of a microfilm reader/printer etc. with each other using cables. The object of the present invention is to provide a remote control device that is easy to operate, allows easy replacement of various parts and systemization, and eliminates the effects of noise caused by the use of cables.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a transmitter that transmits a control signal, and a transmitter that is provided in each of a plurality of controlled devices, and that receives the control signal and It consists of m+ receivers that control controlled devices.

(Example) The present invention will be explained below based on illustrated embodiments.

FIG. 4 shows a microfilm reader printer to which the remote control device according to the present invention can be applied. In FIG.
4 is a screen, 4 is a carrier section for feeding the microfilm, 5 is a printer section, and 6 is a receiver provided in the carrier section 4.

7 is a receiver provided in the printer section 5.

FIG. 1 is a circuit diagram showing the transmitter 1. As shown in FIG.

8 is a keyboard, 9 is an encoder, IO is a modulator, 11
is a carrier generator, and 12 is a transmitter.

FIG. 2 is a circuit diagram showing the receiver 6.

13 is a receiving section, 14 is a preamplifier, 15 is a register, 1
6 is a clock generator, 17 is a decoder, and 8 is a microcomputer that controls the carrier section 4.

FIG. 3 is a circuit diagram showing the receiver 7. As shown in FIG.

19 is a receiving section, 20 is a preamplifier, 21 is a register, 2
2 is a clock generator, 23 is a decoder, and 24 is a microcomputer that controls the printer unit 5.

In the above configuration, the remote control device according to the present invention remotely controls a plurality of controlled devices in the following manner. That is, when the keyboard 8 of the transmitter 1 is pressed, the signal output from the key matrix enters the encoder 9 and is encoded, and then is modulated by the modulator 10 with a carrier signal from the carrier generator 11, and then sent to the transmitter 12. transmitted as an infrared signal.

This transmitter 1 is used to remotely control both the carrier section 4 and the printer section 5 of the microfilm reader/printer, and from the keyboard 8, commands for searching for a desired frame on the microfilm and desired frames can be sent. A command to print is entered manually, and the transmitter 12 transmits a search command signal and a print command signal.

On the other hand, the receiving section 13 of the receiver 6 provided in the carrier section 4
receives an infrared signal sent from the transmitter 12 of the transmitter 1, and amplifies it by the preamplifier 14. This amplified signal is input to the register 15, and the code is determined by the decoder 17 based on the clock signal from the clock generator 16, which is also input to the register 15, and the code is input to the microcomputer 18. This microcomputer 18 sends a reception command to the carrier CPU circuit 37 as shown in FIG. 5 when the code-identified signal is a book film carrier operation command.
By driving the carrier control circuit 38, the carrier section 4 searches for a desired frame on the microfilm.

Further, the receiving section 19 of the receiver 7 provided in the printer section 5
When the microcomputer 24 receives an infrared signal from the transmitter 1, it operates in the same manner as the receiver 6 of the carrier section to determine the code of the received signal. As shown in FIG. 5, the command is sent from the receiver 7 to the printer CPU circuit 35, and the printer control circuit is driven to cause the printer section 5 to print a desired frame.

In the above embodiment, an infrared signal is used as the signal to be transmitted, but it is of course possible to use ultrasonic waves, electromagnetic waves, etc.

(Effects of the Invention) The present invention has the above-described configuration and operation, and receives a control signal from a transmitter with a receiver installed in each of a plurality of controlled devices, thereby remotely transmitting each controlled device. Since it is possible to control multiple controlled devices that perform operations related to W, without having to connect them to each other,
Each controlled device can be easily replaced and systemized.
