Description of the Related Art Conventionally, in a remote control device that operates a plurality of devices such as a video device and a CD player, if M devices have N functions such as power on / off and mode switching, the number of devices is M. The number of remote signal types to be output in order to operate the function selection of each device without any excess or shortage is M × N, and M × N keys are required for that. However, the number of keys for which multiple input was permitted increased in accordance with the number of multiple inputs. In the case of selecting a device using a slide switch, the number M × N is given by the product of the number M of the slide switches and the number N of each function key.

[Problems to be solved by the invention]

In such a remote control device, a slide switch different from a key is provided to increase the number of output signals. However, installing a slide switch increases parts and assembly man-hours. In addition, there is an inconvenience that the defect rate increases due to an increase in the number of steps as well as an increase in the manufacturing cost.

The corresponding data table is selected by the first input data by the first key and the second input data by the second key, and the function data stored in the data table is selected. For example, the first
Assuming that the video tape recorder is selected as the operation target by the operation of the keys, the function data for turning on the power is selected by the operation of the second key, and the operation is started. The function data for channel switching is selected by operating the key 2 to select a channel.

〔Example〕

 FIG. 1 shows an embodiment of the remote control device of the present invention.

The keyboard 2 installed on the operation panel has _{(k + 1) first} keys 2 ₁₁ , 2 ₁₂ ... _{21 (k + 1)} , and N second keys 2 ₂₁ , 2 _{22. n (k + 1)} is installed and each key 2 ₁₁
22 _{n (k + 1)} are arranged in n rows and k + 1 columns with the same type of key.

Such row line L _n of the keyboard 2, the key scan signal KS from the key scan signal output circuit 61 of the configured remote control unit 6 by the IC is added. The key scan signal KS is formed according to a timing signal TM applied from the timing signal generation circuit 62.

Then, by any key 2 ₁₁ to 2 _n of the keyboard 2 _{(k + 1)} is operated, row line L _n and the column lines L _{k + key 1} and is operated 2 ₁₁ ~2 _{n (k +} but it is connected in accordance with _1), the key input data K _i from the keyboard 2 is applied to the key input circuit 63 via the column lines L _{k + 1.}

The key input data K _i is then stored in the data register 64, the fixed memory 65 installed as storage means of the data tables and function data is added as a data read signal.

In the fixed memory 65, k + 1 data tables T ₁ , T ₂ ... T _{k + 1} corresponding to a plurality of devices to be operated such as a VTR and a CD player are set,
Each of the data tables T _{1 to} T _{k + 1} stores n pieces of function data D _{1 to} D _n . That is, keyboard 2
First key 2 _{11-2 1 (k + 1)} is the number of data tables k + 1
Corresponding to the second key _{2 21 ~2 n (k + 1} ) is the data table
Function data D _{1 to} D _n stored in T _{1 to} T _{k + 1}
It corresponds to.

After any data table T ₁ through T _{k + 1} is selected by the key 2 _{11-2 1 (k + 1)} operation, key 2 ₂₁ to 2 _{n (k + 1)}
Function data D ₁ to D _n is selected by the operation, function data D ₁ to D _n which are selected is added to the output circuit 66 via the data register 64.

In the output circuit 66, the read function data
After converting D _{1 to} D _n into a pattern signal, this pattern signal and the clock pulse CLK from the timing signal generation circuit 62 are output.
Are applied to the gate circuit to perform, for example, amplitude modulation, and the modulated output is applied to the base of the output transistor 8 as remote control signal generation means. The output transistor 8 is formed of, for example, an NPN transistor. For example, an infrared light emitting diode 10 is connected to a collector side of the transistor 8 as a remote control signal generating means that is turned on by an operation current flowing by switching of the transistor 8. An infrared output 12 corresponding to the modulation output is output as a remote operation signal corresponding to the device to be operated.

By the way, as shown in FIG. 2, k + 1 data tables T ₁ are stored in the fixed memory 65 of the remote control device.
Through T _{k + 1} is set, each data table T ₁ ~T _{k + 1} function data D ₁ to D _n corresponding to the operation target device is stored. Here, k + 1 data tables T ₁ to
One of a T _{k + 1} is assumed to be set in the priority data table T _{k + 1,} if the data table selection is not performed, always, the priority data table T _{k + 1} is selected. Switch SW indicates a read switching fixed memory 65, the selected data table T ₁ through T _k or priority data table T
by _{k + 1} in which the function data D ₁ to D _n is taken as the output D _0.

FIG. 3 shows a specific configuration example of the remote control device. In this remote control device, for example, as a first key to the first row selecting data tables T ₁ through T _4, 4 pieces of key 2 _11, 2 _12, 2 _13, 2 ₁₄ is installed, the three rows as a second key for two lines to the fourth row selecting function data D ₁ to D _n, 4 rows of keys 2 _21, 2 ₂₂ ...
₂₄₄ are arranged, the same key is used to form a key arrangement of 4 rows and 4 columns, and an infrared light emitting section 16 is provided at the upper end of the outer case 14. Then, in addition to the data table T ₁ through T ₄ to be selected by the key 2 _{11-2 14} to the fixed memory, key 2 ₁₁
Shall priority data table T ₂ not according to to 2 ₁₄ operations are set.

Therefore, for example, when the key 2 ₁₂ is pressed is selected, the data table T ₂ is selected by the selection data table T _2, for example, VTR is selected. Next, when the key 2 ₂₁ is operated, data function data table T ₂ is selected, depending on the choice of the function data, on of the power switch in the VTR, blocking, recording, function selection reproduction mode Done.

Then, when any of the keys 2 _{11-2 14} is also not operated, always, the priority data table T ₂ is selected, only the operation of the key 2 _{21-2 44} is a second key, the data table T ₂
Desired function data D ₁ to D _n is selected from.
Such priority data table T _2, to set the equipment is frequently operation target operation is performed, it is possible the convenience of operation. Therefore, according to such a remote operation, the number of data tables (k + 1) × the number of functions N
, An operation signal corresponding to the selected device is output, a desired device is selected, and an arbitrary operation can be performed.
