BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control transmitter used for AV equipment and the like.

0002

[Background Art] Recently, remote control transmitters (hereinafter referred to as remote controls) have become more and more multi-functional, which not only makes it difficult to remember their operations, but also increases the number of operation buttons, making the remote controls larger. This caused an inconvenience.

[0003] In order to solve the above-mentioned inconvenience, a structure in which one operation button of the remote control has multiple operation functions has been considered.
23 (first conventional example), and Utility Model Application Publication No. 59-45623 (
A second conventional example) has been proposed.

In the first conventional example, a remote control is equipped with a function mode switching key button and a display board, and the function mode switching key button is switched by sliding the display board, thereby allowing a single operation button to have multiple operation functions ( In this example, two) are given.

In the second conventional example, a plurality of switches are arranged relative to one operation button, and a switch to be operated is selected by changing the pressing position on the operation button, thereby providing a plurality of operation functions to one operation button. (4 in this example).

[0006]

[Problems to be Solved by the Invention] However, the above-mentioned conventional example has the following problems.

That is, in the first conventional example, each time the operation function of the operation button is changed, the complicated work of moving the display board and switching the function mode switching key button is required. ■Because the display board is attached to the remote control, the surface of the remote control is uneven and does not look neat.

[0008] In addition, in the second conventional example, (1) multiple switches are required, and the switch to be operated can be arbitrarily selected by changing the pressing position on the operation button, so the operation button can be made small. Moreover, the structure becomes complicated, and the remote control cannot be sufficiently miniaturized. ■Since it is necessary to press the narrow area on the surface of the operation button, the operation becomes complicated and malfunctions occur frequently.

The present invention has been made in view of the above-mentioned circumstances, and provides a remote control transmitter that can eliminate the deterioration in operability and the increase in the size of equipment due to multifunctionalization. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an operation switch section disposed on the surface of the equipment case body, an inclination detection means for detecting the inclination of the equipment case body, and an inclination detection means for detecting the inclination of the equipment case body. A remote control transmitter is provided with function switching means for switching the remote control operation function performed by the operation switch section in response to a tilt signal from the tilt detection means.

[0011]

[Operation] According to the above configuration, when the equipment case body is tilted,
The tilt detection means detects the tilt and transmits a tilt signal to the operation switching means. Upon receiving the tilt signal, the transmission switching means switches the operating function of the operation switch section in accordance with the tilt. In this way, multiple functions are imparted to one operation switch section in response to a simple action of tilting the device case body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below based on embodiments shown in the drawings. FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is a sectional view showing the internal configuration.

This remote control (remote control transmitter) 1 includes an equipment case body 2. As shown in FIG. The device case body 2 has a substantially square shape in plan view. An operation switch section 3 is provided at the center of the upper surface 2f of this device case body 2. Equipment case body 2
A transmitter 7 is provided at one end of the transmitter. Inside the device case body 2, a mercury switch 5 as a tilt detection means and a switching control section 6 as a function switching means are housed.

The operation switch section 3 consists of an operation button 3A arranged at the center of the top surface 2f and a single switch 3B housed in the case body facing the operation button 3A. The mercury switch 5 consists of a total of four pieces 5A to 5D.
Four sides 2a, 2b, 2c, 2 of the equipment case body 2, respectively.
It is placed near d. In addition, each mercury switch 5A ~
5D indicates adjacent side surfaces 2a, 2b, 2c, 2d in plan view
When viewed from the side, each switch is arranged in a diagonal direction with the inner end of the case slightly lowered.

FIG. 4 is a block diagram of the remote control 1 having the above configuration. The mercury switches 5A to 5D transmit tilt signals S1 to S4 to the switching control section 6. The operation switch section 3 transmits a transmission instruction signal S5 to the switching control section 6. Tilt signal S1~
The switching control unit 6, which has received S4 and the transmission instruction signal S5, sends transmission instruction signals S6 to S9 based on the slope signals S1 to S4.
is transmitted to the transmitter 7. The transmitter 7 that has received the transmission command signals S6 to S9 transmits remote control signals R1 to R4 for each operation function to the main device (not shown) by infrared light emission or the like based on the transmission command signals S6 to S9.

Next, the operation of the remote control 1 having the above configuration will be explained.

If the device case body 2 is held in a horizontal state, all the mercury switches 5A to 5D are in the tilted state of off operation, and the tilt signal S1 is output from each mercury switch 5A to 5D.
~S4 is not transmitted. For example, as shown in FIG. 3, when the device case body 2 is tilted downward to the left in the figure and the operation button 3A is pressed, the mercury switch 5B
The mercury switch 5B enters a tilted state of ON operation, and the mercury switch 5B transmits a tilt signal S2, and the operation switch section 3 transmits a transmission instruction signal S5 to the switching control section 6. The switching control unit 6, which has received the tilt signal S2 and the transmission instruction signal S5, transmits a transmission command signal S7 to the transmitting unit 7 in response to the tilt signal S2. Upon receiving the transmission command signal S7, the transmitter 7 transmits a remote control signal R2 indicating a function corresponding to the signal S7, that is, a channel up operation function, to the main device.

Similarly, when the device case body 2 is tilted downward to the right and the operation button 3A is pressed, only the mercury switch 5A is turned on and the transmitter 7 is turned on.
A remote control signal R1 indicating a channel down operation function is transmitted from the terminal. Further, when the device case body 2 is tilted forward and downward and the operation button 3A is pressed, only the mercury switch 5D is turned on and the transmitter 7 is turned on.
Remote control signal R meaning volume up operation function
3 is sent. Furthermore, when the device case body 2 is tilted backwards and the operation button 3A is pressed, only the mercury switch 5C is turned on and the transmitter 7 is tilted.
Remote control signal R meaning volume down operation function
4 are respectively transmitted to the main device. In this manner, in this embodiment, one operation switch section 3 can select and transmit four remote control signals R1 to R4.

In the above embodiment, the remote control signals R1 to R4 are transmitted only when the device case body 2 is tilted and the operation button 3A is pressed.
State where the device case body 2 is horizontal (Mercury switch 5A ~
To make it possible to transmit a remote control signal even when an operation button 3a is pressed with the equipment case body 2 turned upside down (all mercury switches 5A to 5D are turned on) or when the operation button 3a is pressed. can also be considered. Furthermore, depending on the tilting direction, a plurality of mercury switches 5A to 5D may be turned on, and it is also possible to selectively transmit remote control signals even in such a state. In this way, it is also conceivable to provide more than one operation function to one operation switch section 3.

Further, in the above embodiment, the mercury switches 5A to 5D are used as the inclination detecting means, but it goes without saying that the present invention is not limited to this.

In addition, in the above embodiment, the remote control has only one operation switch section 3, but
Needless to say, the present invention can also be implemented in a remote control having a plurality of operation switch sections 3.

[0022]

As described above, according to the present invention, multiple remote control operations can be performed with one operation switch section by a simple selection operation of tilting the device case body. The operability of the transmitter has been improved.

Furthermore, since the inclination of the device case body is detected by the inclination detection means and the operating function of the operating switch section is changed according to the inclination, the operating function of the operating switch section can be adjusted without complicating the mechanism. Multifunctionality can be achieved, and the disadvantage of increasing the size of the remote control transmitter does not occur.
