Abstract

PURPOSE:To control a device not controlled directly such as a device of a different manufacture by storing a reception code and comparing it with a code stored from a reception circuit and selecting and sending a transmission code corresponding to the device to be controlled. CONSTITUTION:The code sent by other remote controller 1 is received by a reception circuit 2 and a code comparison circuit 4 compares it with a code registered by a code storage circuit 3. When they are coincident, the transmission code corresponding to the reception is extracted by the transmission code selection circuit 5 from the code storage circuit 3 and sends it from the transmission circuit 6. Thus, other remote controller 1 used to control a device 7 to be controlled which cannot be controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote controller device, and particularly to a remote controller device using infrared rays.

[Conventional technology]

Generally, remote controller devices are used as command devices for remote control of home appliances such as televisions, video cameras, and stereo devices.

Conventionally, such a remote controller device has rarely been able to control only one type of television, stereo equipment, stereo equipment, etc. Furthermore, in recent years, many devices from the same manufacturer can control multiple models, such as televisions, video cameras, and even video disk players. Alternatively, some remote controller devices can receive and store transmission codes from other remote controller devices, making it possible to operate any device regardless of manufacturer or model.

[Problem to be solved by the invention]

Among the conventional remote controller devices mentioned above, those that can control multiple devices from the same manufacturer, such as TVs and video cameras from the same manufacturer, are
Unless there are devices that can be controlled by a controller, there is a drawback that they cannot be controlled by a single remote controller.

On the other hand, remote controllers that can receive and store codes enable control with a single remote controller regardless of the manufacturer or model of the device being controlled. While a remote controller is dedicated to the device, this type of remote controller is a general-purpose type, so the number, arrangement, and shape of keys are appropriate for the operation section depending on the content to be controlled. There are disadvantages in terms of operation, such as not being able to use the keys and having to memorize the correspondence between keys and control contents (codes).

An object of the present invention is to provide a remote controller device that can control devices that cannot be directly controlled, such as devices from different manufacturers.

[Means to solve the problem]

The remote controller device of the present invention includes a receiving circuit that receives a transmission code from another remote controller, a memory circuit that stores the received code, and a code from the receiving circuit that is compared with a code in the memory circuit. The control device includes a code comparison circuit that selects and transmits a transmission code corresponding to the controlled device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a remote controller device for explaining a first embodiment of the present invention.

As shown in FIG. 1, the remote controller device of this embodiment includes a receiving means 2 for receiving codes transmitted from other remote controllers 1, a code storing means 3 for storing the received codes, and a receiving circuit 2. a code comparison circuit 4 that compares the code from the registered storage circuit 3 with the code from the storage circuit 3; a transmission code selection circuit 5 that selects a transmission code based on the output of the code comparison circuit 4 and the output of the storage circuit 3; and a transmission circuit. 6, and remotely controls the controlled device 7.

Note that the codes used for reception, comparison, and transmission are registered in advance. The actual operation of such a remote controller device is as follows.

Is the code sent by Roller 1 received by another remote controller? 82 receives the code, and the code comparison circuit 4 compares it with the code registered in the code storage circuit 3. If there is a match, the transmission code selection circuit 5 extracts the transmission code corresponding to the reception code from the code storage circuit 3 and transmits it from the transmission circuit 6. This makes it possible to use another remote controller 1 to control a controlled device 7 that cannot be controlled by itself.

FIG. 2 is a block diagram of a name-based mote controller device illustrating a second embodiment of the present invention.

As shown in FIG. 2, this embodiment provides an output code to the remote controller device in the first embodiment.
A programming means 8 is added thereto. As a result, in the first embodiment described above, only one type of code was transmitted corresponding to the received code, but two or more types of codes are transmitted consecutively, and one operation of the other remote controller 1 is performed. This makes it possible to issue multiple operation commands to multiple devices. This operation is effective when turning on/off the power of multiple devices all at once.

FIG. 3 is a block diagram of a remote controller to a roller device for explaining a third embodiment of the present invention.

As shown in FIG. 3, this embodiment is obtained by adding a timer-based time control circuit 9 to the remote controller device in the second embodiment described above. As a result, in the second embodiment, each time a mode sent from another remote control roller 1 is received, multiple types of codes are sent once, or multiple types of codes are sent to multiple types of codes. It is possible to send multiple times. This operation allows a television without a timer device to be controlled by time. That is, this is effective when the volume is gradually lowered every few minutes and the power is turned off after i = 6-.

〔Effect of the invention〕

As explained above, the remote controller device of the present invention has the advantage that it is possible to control equipment that cannot be directly controlled using a conventional remote controller, such as equipment from a different manufacturer.
