Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation mode setting device for a control device, such as an electronic counting device, which has a built-in setting switch that can set or switch between a plurality of operation modes.

In general, in electronic counting devices, various specifications (operating modes) such as time specifications, count mode specifications, numerical display method, output operation mode, response speed, power supply frequency specifications, etc. are controlled by changing internal logic circuits or by internal software programs. It can be changed by switching the change.

A setting switch for switching this internal logic circuit or internal software program is installed inside the front panel of the case to prevent accidental operation from the outside, and an opening hole is provided in the front panel at a location corresponding to the setting switch. A device is provided in which the setting switch can be operated through this opening using tweezers, a screwdriver, etc., and a protective cover is detachably attached to the opening.

However, many setting switches are small, and if the actuator or pushbutton of such a small setting switch is forcefully operated with tweezers or a screwdriver, as described above, the setting switch may be damaged. There was also the hassle of having to prepare tweezers and a screwdriver each time the user wanted to change the specifications.

The present invention was developed in view of the above problems, and allows the operation of a control device that allows safe and reliable operation of the setting switch when setting or switching the operation mode, and does not require any tools such as tweezers or screwdrivers. The present invention aims to provide a mode setting device.

The present invention will be explained below based on an example.

1 and 2 show an electronic counting device which is an example of a control device, where 1 is the main body of the device, 2 is a numerical display section consisting of a light emitting diode provided on the front panel 1a of the main body 1, and 3 is 4.
Numeral setting section 4 is made up of 11 digital switches arranged in parallel, and 4 is a setting switch made up of 11 small slide switches installed inside the main body 1 of the device.

This setting switch 4 is used to change the internal logic circuit or internal software program.
Count mode specifications, number display method, output operation mode.

It is possible to change various specifications (under operating mode) such as response speed and power frequency, and a total of 211 = 2048 settings and changes are possible by turning each switch ON and OFF.

A horizontally elongated opening 5 is provided in the front panel 1a of the device body 1 at a position corresponding to the setting switch 4, and the operating button 4a of the setting switch 4 can be operated through this opening 5. .

A protective cover 6 as shown in FIG. 3 is removably attached to the opening 5, and the surface of the protective cover 6 shows the results of switching various specifications such as time specification, count mode specification, output operation mode, etc. (not shown) is displayed.

Further, at the end of the protective cover 6, an operating piece 7 having a predetermined length l is provided to protrude laterally.

8 is a volume for adjusting the pulse width of the output, 9 is a reset switch for performing initial settings after completing a series of setting operations, 10 is a reset indicator light, and is located on the front panel 1a.
Opening holes 11 and 12 are provided at positions corresponding to the volume 8 and reset switch 9, respectively.

The operation button 4a of the setting switch 4, the knob 8a of the volume control 8, and the actuator 9a of the reset switch 9 are all operated by the operation piece 7 of the protective cover 6, as shown in FIGS. 4 to 6.

At this time, the operation button 4a, knob 8a and actuator 9a are moved from the surface of the front plate 1a to the operation piece 7.
Since it is installed at a position that extends inward by approximately the same length as the length l, the tip of the operating piece 7 of the protective cover 6 engages with the operating button 4at knob 8a or the actuator 9a, and the The end surface 6a is the front plate 1a
Touch the surface of the setting switch 4. Excessive operating force is not applied to the volume 8 or the reset switch 9.

Figures 4 and 5. The arrow in FIG. 6 indicates the operating direction of the protective cover 6.

Note that the operating piece 7 of the protective cover 6 in the present invention is the third
The operation piece 7' is not limited to the one protruding laterally from the end surface of the protective cover 6 as shown in the figure, but may be provided, for example, as shown in FIG. 7, inwardly protruding from the protective cover 6I0).

In this case, it is necessary to make the operation piece 7' a little longer than the one shown in FIG. 3 in consideration of the fitting size of the protective cover 67(7) into the aperture 5.

In addition, in the case of FIG. 3, since the operating piece 7 is exposed on the surface of the front plate 1a when the protective cover 6 is attached to the opening hole 5, the operating piece 7 is in the correct direction when the protective cover 6 is attached. In addition, there is an effect that the protective cover 6 can be easily removed from the opening 5 by hooking the operating piece 7 with a finger.

As is clear from the above explanation, according to the present invention, since the operating piece is integrally provided on the protective cover, the setting switch can be operated with the operating piece when setting or switching the operation mode, and it is possible to use a screwdriver with tweezers or a screwdriver. Such tools are completely unnecessary.

In addition, the operating piece is formed to a predetermined length depending on the installation depth from the front plate of the setting switch, so when the setting switch is operated, the side or end surface of the protective cover will come into contact with the front plate, causing the setting switch to Excessive operating force is not applied.

Therefore, damage to the setting switch can be prevented, and safe and reliable operation is possible.

Note that the setting switch in the present invention is a concept that includes various setting/switching means such as the volume 8 or the reset switch 9 in addition to the setting switch 4 described above.
