Abstract

PURPOSE:To appropriately charge a battery for a transmitter and to prevent a remote transmitter from being inoperable due to the dead battery by providing an equipment to be controlled with a charging means charging an accumulator for the remote transmitter. CONSTITUTION:When a remote controller is applied to a microfilm reader/ printer, since a retrieval device main body 1 as a device to be controlled and the transmitter 7 for remote control are charging type, the transmitter 7 is loaded on the fitting part 6 of the retrieval device main body 1 through a connector part 30, a current from a power source 31 is conducted in the circuit of the transmitter 7, and charges the accumulator 35 through a current limit resistance 34. At that time, a diode 33 is provided, and therefore the current is never conducted reversely even if the accumulator 35 discharges. Simultaneously the current is conducted in a voltage adjustment resistance 36, whereby a switching transistor 37 operates to drop the power source voltage of a reception circuit 38. Even if a signal inputs to a light receiving part 5, the retrieval device main body 1 is caused not to operate, and malfunction and the flow of an unnecessary current to the reception circuit can be prevented.

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, microfilm reader printers search for images on microfilm wound in a roll.
An input device such as a Keysade is provided to input detailed search information, but if this input device is connected to a microfilm reader/printer using a cable, etc., the degree of freedom when searching is reduced. Because of this, search by remote control is now becoming a reality.

That is, as shown in FIG. 6, this type of remote control device operates a key 62 of a remote control transmitter 61 to send a signal from a transmitting element 63 to a remote controlled device (not shown). There are elaborate configurations in which the controlled device is remotely controlled.

(Problem to be Solved by the Invention) However, in the case of such conventional technology, since a battery is used as a power source for the remote control transmitter 51 in most cases, the voltage drop of the battery during use may cause the battery to become unused. As a result, there is a problem in that the search efficiency is reduced.

Therefore, the present invention was made in order to solve the above-mentioned problems of the conventional example, and its purpose is to provide a remote control device that does not become unusable due to running out of battery during use. It's about doing.

(Means for Solving the Problems) In order to achieve the above object, the present invention transmits a control signal from a transmitter, and transmits the control signal by a receiver provided in a controlled device. In the remote control device that receives υ and remotely controls the controlled device, the controlled device is provided with charging means for charging a storage battery of the transmitter.

(Function) In the present invention, the controlled device is provided with a charging means for charging the storage battery of the transmitter, so that the transmitter can be charged as appropriate.

(Example) The present invention will be explained below based on the illustrated example. Second
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 main body as a controlled device, and 2 is a device that displays an image of a microfilm. 3 is a part of the printer; 4 is a microfilm search section; 5 is an infrared receiving section; 6 is a mounting section for a charging transmitter; and 7 is a remote control transmitter.

3. FIG. 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 transmitter 7 presses the keyboard 11, the control command signal enters the encoder 12 and is pulsed; at this time, the check code stored in the memory is also encoded by the encoder 12, and the control command signal is 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, in the receiver, the infrared signal from the transmitting section 15 is received by the receiving section 5, inputted into the register 22, and the control signal and check code whose code is determined by the decoder 23 are inputted into the microcomputer 24. This microcomputer 24 drives the search unit 4 and printer part 3 in the search machine main body 1 as a controlled device in accordance with the code-identified control signal.

Here, since the transmitter 7 is rechargeable, it is always fixed to the mounting portion 6 and charged when the search device main body 1 is not in use. This charging circuit is shown in FIG. 1, where 30 is a connector between the search device body 1 and the transmitter 7, 31 is a power source, 32 is a load (transmission circuit in this embodiment), 33 is a diode for preventing backflow, 3
4 is a current limiting resistor, 35 is a storage battery such as nickel-cadmium, 36 is a voltage adjusting resistor, 37 is a switching transistor, 38 is a receiving circuit including the register 22, decoder 23 and microcomputer 24 shown in FIG.
1 is a receiving section in FIGS. 1 and 4, which is composed of a photodiode.

In the above configuration, the mounting portion 6 is connected via the connector portion 30.
When the transmitter 7 is attached to the transmitter 7, current flows from the power supply 31 to the circuit inside the transmitter 7, passes through the current limiting resistor 34t, and charges the storage battery 35. At this time, by providing the diode 33, reverse current will not occur even if the storage battery 35 is discharged. Furthermore, at the same time as described above, current also flows through the voltage adjustment resistor 36, so that the switching transistor 37 is activated and the power supply voltage of the receiving circuit 38 is lowered. At this time,
Even if a signal or external light is input to the receiving section 5 made of a photodiode, the receiving circuit 38 does not accept it.

In this way, since the signal input prohibition circuit is provided so that the search device main body 1 does not operate even if a signal is input to the light receiving section 5 in the charging state, the transmitter 7 can be removed even in a place where multiple devices are installed. Unless otherwise specified, the transmitter can be used as a so-called key without malfunctioning and causing unnecessary current to flow in the IB receiving circuit.

Note that the present invention is not limited to the above-mentioned embodiment. For example, in the above-mentioned embodiment, the power supply to the receiving circuit 38 is turned off by the switching transistor 37, but a power supply other than the charging power supply 31 is used. That is, if the power to the search device main body 1 and the like is turned off by the switching transistor 37, the transmitter 7 can be used as a switch, and there is no need to turn the switch on and off each time it is used. Furthermore, as a substitute for the switching transistor, if a push button is provided near the connector 30 and attached to the transmitter 7t-connector section 30, the circuit can be cut off by the push button.
An input prohibition circuit is not required, and the circuit can be simplified.

Furthermore, in the above embodiment, the input prohibition circuit is omitted, and as shown in FIG. If it is configured so that it comes into contact when it is attached to the attachment part 6,
The search device main body 1 can be operated even while charging, and can be used even when the transmitter 7 is not fully charged. This also means that the receiving part 5 and the transmitting part 15 do not necessarily have to be in contact with each other, but as long as the receiving part 5 is in a position where it can be operated reliably during charging, even if there is some distance between the mounting part 6 and the receiving part 5. good. Moreover, it goes without saying that the above is not limited to remote control using infrared rays.

(Effects of the Invention) The remote control device according to the present invention has the above-described configuration and operation, and since charging means for charging the storage battery of the transmitter is installed in the controlled device, the battery runs out during use and becomes unusable. This eliminates the hassle of replacing batteries.
Moreover, by determining the installation location of the transmitter, it is possible to improve efficiency at the time of starting use and to prevent the transmitter from being lost.
