Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a switch operation unit with an illumination function in an electronic surveying instrument.

[Prior art and its problems] Conventionally, in the switch operation section of electronic surveying instruments that measure angles and distances, in order to satisfy a large number of input functions with the minimum number of switches, each switch has multiple inputs. It has a function.

These switches are set so that only some of them are valid (that is, input is possible by turning the switch ON) depending on the various operation modes of the electronic surveying instrument, and the The plurality of input functions are also set to be selectively enabled according to the operation mode.

For example, two functions f1. Regarding the switch Sx having f2, it is valid only when the operation mode of the electronic surveying instrument is m8 or m2, and is invalid in m, and one of the functions f is valid when the operation mode is m. Then, the other function f is disabled, and when the operation mode is m2, the other function f2 is enabled and one function f1 is disabled.

However, in the past, no means was taken to distinguish and display the currently valid switches and input functions, so there was a waste of time for the operator to press invalid switches. Operators must be familiar with the appropriate switch operation procedures depending on the operating mode of the electronic surveying instrument, which places a heavy burden on the operator.

In addition, it may be difficult to identify the switch at night or in a dark place, resulting in extremely poor operability.

[Object of the Invention] The present invention has been proposed in view of the above points, and its purpose is to prevent erroneous operations and to help operators by illuminating switches corresponding to currently valid input functions. It is an object of the present invention to provide a switch operation section for an electronic surveying instrument that reduces the operational burden on the operator and can be easily operated even in a dark place.

[Structure of the Invention] In order to achieve the above object, the present invention provides an illumination function to each switch, and provides an electronic 31! The gist is to display whether a switch is valid or invalid by illuminating the display section of the switch corresponding to the input function that is valid in the current operating mode of the I-quantity machine.

Further, in the present invention, when each switch has a plurality of input functions, the plurality of display sections corresponding to these functions are selectively illuminated.

Furthermore, by changing the illumination mode of each switch as necessary, the functions of each switch can be roughly classified, or the switches can be grouped according to related functions, and each switch can be provided with a representative illumination function.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an operation switch section S according to the present invention.
Six switches 1 to 16 are arranged vertically and horizontally within the front panel 100. These switches 1-1

The display panel of each of the switches 1 to 16 is provided with a display section that displays individually assigned operation input functions and numerical input functions using abbreviations and numbers. For example, switch 1 has the function [V/
H] and a function to input the numerical value "7", and each display section 1a is formed by dividing the surface of the switch button into upper and lower halves.

Further, light emitting diodes a and ILb are provided as light sources corresponding to the display sections 1a and 1b. One end of the contact S1 is connected to an input determination circuit 21 that detects the input state of the switch 1 and determines whether or not the input is valid. The output of this input determination circuit 21 is applied to an input function processing circuit 22,
In this input function processing circuit 22, the operated switch 1
If the input function is valid, processing is performed according to the input function. The output of the input function processing circuit 22 is sent to the effective function determination circuit 23.
In addition, this valid function determining circuit 23 exchanges data with the input determining circuit 21, and determines the currently valid input function based on the data from the input function processing circuit 22. The LED drive circuit 24 at the next stage receives the output from the valid function determination circuit 23 and drives the switch corresponding to the currently valid input function, for example, the light emitting diode ILa or the light emitting diode ILa of the switch 1. The terminals are connected to the anodes of the light emitting diodes a and ILb.

This configuration is exactly the same for the other switches 2, 3.5 to 15, and in the switch 16 (same as for switch 4), which has only a single input function, the LE

Here, to explain in detail the functions of switches 2 to 16 other than switch 1, switch 2 has the function of specifying the horizontal angle measurement direction, that is, clockwise/counterclockwise [R/L];

is the function to set the standard mode [A I Ml and “1

The switch 12 has a function [MEAS] that performs precision measurement in distance measurement related mode, and a clear function [CL] that sets the setting input value to Z.
], the switch 13 has the function of displaying and setting the machine point coordinates X, Y, Zo.

Switch 14 has the function of displaying the stakeout setting value and inputting the setting [SO], and the function of shifting the cursor position to the left during setting input [←]. The switch 16 indicates the function to display and input the set values for temperature T and atmospheric pressure P [T/Pl and the function to shift the cursor position to the right when inputting the settings [→], and the switch 16 indicates the completion of the setting when inputting the settings. function [E
Each is equipped with NTI.

The functions of these switches 1 to 16 are mutually dependent on each other in terms of effectiveness according to the logic circuit by the CPU provided in the electronic surveying instrument. The numerical input functions of ~11 and 13 are enabled by switches 13, 14, and 15tc [X, Y, Z,], [SO].

This function is only valid when inputting settings for [T/P] mode, and the [REPEAT] function by switch 3 is valid only when setting [V/H] and [HOR/HE modes by switches 1 and 5. It has become. An example of this relationship is shown in Table 1 below for the operation modes [V/H, [SLP/v] and [SO].

Table 1 In Table 1, the main function is an input function that is valid within that operating mode, and the sub-function is another input function that can be transitioned to in that operating mode.

Next, this operation will be explained with reference to Table 1.

First, it is assumed that the current operating mode of the electronic surveying instrument is [v/H] by operating the switch 1. Based on this operation mode [V/H], the valid function determination circuit 23 determines the valid input functions in the current state as [R/L, [REPEAT], as shown in Table 1.

[2″’SET] (7) Main function and [HOR/H1.

[SLP/Vko, [VER/Z], [X

It is determined that it is a sub function of [X, Y, Z,], [T/P]. This sends a signal to the next stage LEDyjA8 circuit 24 to drive a specific light emitting diode,
The LED drive circuit 24 lights up the light emitting diodes provided in the display parts of the switches 2 to 4, 5 to 8, 13, and 15 corresponding to the above-mentioned effective functions. Therefore.

For all the switches 2, 3.5 to 8.13.15, the upper display section is illuminated, and for the switch 4, the entire surface of the display section 4a is illuminated by a single light emitting diode.

In other words, in this state, the illuminated switch 2
~4, 5~8.13.15 Only the relevant functions are valid, and even if a switch that is not illuminated, for example switch 9, is operated, the valid function determination circuit 23 will indicate the currently valid input function. The input determination circuit 21 which has taken in the data regarding the switch 9 determines that the input operation of the switch 9 is invalid, and rejects the input without sending a signal to the subsequent input function processing circuit 22.

In this state, for example, if the switch 2 corresponding to [R/L], which is a valid main function, is turned on, the input determination circuit 21 determines that the input is valid, sends a signal to the input function processing circuit 22, and The function processing circuit 22 performs a process of setting the measurement direction of the horizontal angle.

Next, in the valid state of each of the above-mentioned functions, when the switch 6 is turned on to shift to the sub-function [SLP/Vl operation mode, the valid function determination circuit 23 performs the following operations as shown in Table 1 by the same operation as described above. < [AIM],
The main functions of [TR], [AV], [MEAS] and [V/H1, [HOR/H].

[VER/Zl, [X/Yko, [X1lY
IIZ11] - [SO3, [T/P] sub-functions are determined to be valid, and predetermined light emitting diodes corresponding to the above-mentioned functions are turned on via the LED drive circuit 24.

As a result, switches 2 to 4.6, which were lit up until then,
The light emitting diode of will disappear and switch 1.9~12 will turn on instead.
．． The light emitting diodes in the upper display section of 14 are lit.

In this state, when the switch 14 corresponding to the sub function C8O] is set to ONL and the switch 14 is moved to the operation mode of [SO3], the first
As shown in the table, valid input functions are numerical input function, [←]
and [→] cursor shift function, [+/-1
, [CL], [ENT]. Therefore, all the light emitting diodes in the display section at the top of each switch go out, and the switches 1 to 3, 5 to 7, 9 to 11, and 13 corresponding to the numeric keypad are turned off.
and cursor shift function switches 14.15. The light emitting diodes corresponding to the lower displays of the code input switch 8 and the clear switch 12 light up, and the switch 1
6 is fully illuminated. However, in this operation mode, the effective function differs depending on the cursor position; for example, when the cursor position is at the left end, [10/-1].

[→], [CL], [ENT] functions only, and when the cursor is at the right end, numerical input function and [←]
, [CL], and [ENT] functions are enabled.
The corresponding light emitting diodes and display sections illuminate. Thereafter, the illumination pattern changes in accordance with the effective function that changes each time an input operation is performed using the switch.

Note that in this embodiment, the mode of illumination is not differentiated between the main function and sub-function corresponding to each operation mode; By changing the illumination mode by flashing or flashing one side,
Functions can be determined more effectively.

Next, FIG. 3 shows another embodiment of the present invention, in which each switch 1' to 16 is
' are divided into four groups according to main functions and sub-functions, and display sections 17 to 20 representing these groups are provided separately from switches 1' to 16' in one-to-one correspondence to each group. There is. In this case, a light source such as a light emitting diode is housed in the five display sections 17 to 20.

According to this embodiment, the number of light sources can be further reduced, and the drive circuit for illumination can be simplified, resulting in cost reduction.

In one or more of the embodiments, the explanation will be centered on a switch having a plurality of input functions, but the present invention is of course also applicable to a switch operation section consisting of a plurality of switches each having a single input function. . Furthermore, the type of light source for illumination is not limited in any way, as long as it satisfies a predetermined illumination function other than a light emitting diode.

[Effects of the Invention] As described above, the present invention illuminates the display section of the switch corresponding to the input function that is valid in the current operating mode of the electronic surveying instrument to indicate the validity of the switch. There is no inconvenience of pressing an invalid switch, and the input operation can be simplified and the burden on the operator can be significantly reduced. In particular, even if the operating mode changes over time, the illuminated switch display changes accordingly, indicating the valid input function each time, so even inexperienced users can perform accurate input operations. I can do it.

Furthermore, the illumination function of one display section has the advantage of allowing quick and easy input operations even at night or in a dark place.゛
