Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control transmitter, and more particularly to an infrared transmitter for audiovisual equipment.

[Conventional technology]

Generally, a remote control transmitter used for audiovisual equipment, etc. has a structure as shown in FIG.

That is, four lines in the column direction of the matrix 30 having a 4×4 matrix are connected to the strobe output circuit 31, and four lines in the row direction are connected to the key input circuit 32. The strobe output circuit 31 and the key input circuit 32 are connected to a key detection circuit 34, and the strobe output circuit 31
The operation timing control of the key input circuit 32 and the signal analysis of the key input circuit 32 are performed.

A single circuit switch 3 is provided at each intersection of the matrix 30.
3 are connected, and when any switch 33 is pressed, the output signal of the strobe output circuit 31 is input to the key input circuit 32 and analyzed by the key detection circuit 34.

Thereafter, a code is created by a code creation circuit 35 connected after the key detection circuit 34, and the carrier from the carrier generation section 36 is modulated with this code and transmitted.

[Problem that the invention seeks to solve]

However, in the conventional device described above, each switch 3
3 is fixedly assigned to a specific function (device operation mode), so in order to control many operation modes, the same number of switches as the number of operation modes are required, resulting in high costs. be.

Another way to control many operating modes with a small number of switches is to assign multiple functions to one switch, but this requires a separate switch to change the function of the switch, making operation cumbersome. There is.

If more functions are covered, a large number of keys that are not used by the user will be listed, which may make operation inconvenient.

The present invention has been made in view of the above-mentioned problems, and its technical object is to provide a remote control transmitter that allows desired functions to be easily operated with a small number of switches.

[Means for solving problems]

In order to solve the above-mentioned technical problem, the present invention provides a remote control transmitter in which a transmitter main body l is equipped with a plurality of key switches 2, and a remotely controlled device is operated by operating the key switches 2. The structure was as follows.

That is, a plurality of key switch accommodating parts 3 are formed in the transmitter main body l, and each key switch accommodating part 3
A plurality of contacts 4 are provided which are connected in parallel between each key switch accommodating portion 3.

On the other hand, the key switch 2 is connected to the key switch housing section 3.
The transmitter is formed to be detachably attached to the transmitter, and is provided with terminals 5 corresponding to the contacts 4, and configured to connect these terminals 5 through a predetermined path by operating a switch, thereby forming a transmitter for remote control.

[Effect]

Multiple key switches can be detachably attached to the transmitter body, and the key switch is configured to connect the terminals provided on the key switch through a predetermined path, so it is unique to the key switch. The code can be shared.

Therefore, key switches having desired functions can be arranged and used at desired positions on the transmitter body.

〔Example〕

Embodiments of the present invention will be described based on FIGS. 1 to 5.

The transmitter main body 1 has a box shape, and a plurality of key switch accommodating portions 3 are formed in the transmitter main body 1. The key switch accommodating portion 3 is a rectangular recessed portion, and a total of 16 key switch accommodating portions are formed in four rows and four stages.

Each key switch accommodating part 3 is provided with a plurality of contacts 4 connected in parallel between each key switch accommodating part 3.

These contacts 4 are provided on two sides of each key switch accommodating portion 3, and a total of 16 contacts are provided, 8 on each side.

The key switch 2 is detachably attached to these key switch accommodating portions 3.

This key switch 2 consists of a base part 2a that fits into the key switch housing part 3 and a push button part 2b,
Terminals 5 corresponding to the contacts 4 are provided on the side surface of the base portion 2a, and the terminals 5 are configured to be connected through a predetermined path by operating a switch. Further, the contents of the function are displayed on the upper surface of the push button section 2b, such as "playback" for a VTR.

When in use, the key switch 2 of a desired function is attached to a desired key switch accommodating portion 3.

A specific example of the circuit configuration will be explained based on FIGS. 2 and 3.

As shown in FIG. 3, the plurality of contacts 4 connected in parallel between the key switch accommodating parts 3 are connected to a matrix circuit 6, and the eight connecting lines 6a in the row direction are connected to a key input circuit 7. The eight connection lines 6b in the column direction are connected to the strobe output circuit 8.

On the other hand, the key switch 2 has eight connection lines 6a in the row direction.
and eight connection lines 6b in the column direction are connected through a predetermined route, and a code corresponding to a preset function is selected. This code can be set up to 64 types (from 8×8).

The strobe output circuit 8 and the key input circuit 7 are connected to a key detection circuit 9, so that the operation timing of the strobe output circuit 8 and the signal analysis of the key input circuit 7 are controlled.

Furthermore, a code is created by a code creation circuit IO connected after the key detection circuit 9, and the carrier from the carrier generation section 11 is modulated with this code and transmitted.

As described above, since a unique code can be set for each key switch 2, this key switch 2 can be used by being attached to a desired key switch housing 3.

4 and 5 show other embodiments, in which the key detection circuit 9
The input/output to and from the strobe output circuit 8 is performed using 16-bit binary code.

In this example, there are 32,767 types of codes (from 2-1)
It can be set up to.

The operation is the same as that of the previous embodiment, so a description thereof will be omitted.

〔Effect of the invention〕

According to the present invention, a plurality of key switches can be detachably attached to the transmitter body, and the terminals provided on the key switches are connected through a predetermined route. It is possible to share the unique functions of each key switch.

Therefore, key switches having desired functions can be arranged and used in desired positions, and
The functions can be carefully selected and the operability is extremely good.
