Abstract

PURPOSE:To attain a device to be used conveniently by a user by providing two different types of operating surfaces to the case of a keyboard device. CONSTITUTION:A keyboard main body (key unit) 1 in the keyboard device is fitted in the upper recessed part of the device case 2, and both front and back surfaces different in key array. Moreover, a rotating mechanism part 3 is disposed in the upper recessed part of the device case 2 to invert the key unit part 1, whereby both the front and back surfaces can be appropriately selected. A switch 4 is installed to discriminate which operating surface is operable. Thus the keyboard with a unique array in accordance with the usage and input format can be obtained without limiting to one type, and therefore complicated programs can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard device used as a data input means, and more particularly to a keyboard device in which two types of key layouts can be switched by simply turning the keyboard body over. .

[Conventional technology]

Conventionally, this type of keyboard device supported a keyboard body with a key layout unified according to the JIS standard for data input, but this was limited to one device per device.
As a general rule, the number of keyboard devices increased as the key arrangement changed to suit the device function, and these keyboards were replaced depending on the purpose.

[Problems to be solved]

As explained above, it is necessary to have a keyboard device with a key arrangement suitable for the purpose of the multi-functional device, and as the device becomes multi-functional, the number of types of devices increases and the device becomes complicated. Also, as the number of uses increases, the same key layout has the disadvantage that operability inevitably deteriorates, and even if you change the keyboard to suit each use, you have to turn off the power and replace the keyboard each time. However, there was a drawback that the operation was complicated.

[Means for solving problems]

In order to meet these demands, the present invention provides a keyboard with a different layout, that is, a unique key layout suitable for the use of the device.
Keyboards with standard key layouts specified by JIS standards, etc. are housed in the same keyboard device, and these operation surfaces can be identified with a mechanism that allows easy selection of either operation surface as required without replacing the entire operation surface. An object of the present invention is to provide a keyboard device having a switch.

To this end, the present invention provides a keyboard device used as an input means, in which two input operation surfaces are mounted on the front and back sides of one keyboard body, and a rotating mechanism unit capable of flipping the operation surfaces; The present invention provides a keyboard device characterized in that it is provided with a switch that can be identified by a control device.

〔Example〕

Next, the present invention will be specifically described with reference to the accompanying drawings.

FIG. 1 is a perspective view of an embodiment of the keyboard device of the present invention. FIG. 2 shows the key arrangement on one operating surface of the embodiment shown in FIG. 1, and FIG. 3 shows the key arrangement on the other operating surface. FIG. 4 is a sectional view of the embodiment of FIG. 1. FIG. 5 is an explanatory diagram of the rotation mechanism section of the embodiment shown in FIG.

Reference numeral 1 denotes a keyboard body, that is, a key unit portion of the keyboard device of the present invention, which is fitted into a recess on the upper surface of a keyboard device housing 2. As shown in FIG. The key unit section 1 has different key layouts on both the front and back operation surfaces. Examples of such key layouts include those shown in FIGS. 2 and 3, for example. Reference numeral 3 denotes a rotation mechanism section disposed in a recess on the upper surface of the keyboard device housing 2, and by reversing the key unit section 1, both the front and back operation surfaces can be selected as appropriate. The rotation mechanism part 3 has a fulcrum 6 connected to a part of the key unit part 1, a guide groove part 7 that guides the connection part between the fulcrum 6 and a part of the key unit part 1, and both ends of the guide groove part 70 are enlarged, respectively. and a switch 4 disposed near one of the stopper parts 5 to identify which of the operation surfaces of the key unit part 1 is in an operable state. ing.

Furthermore, the operation of the keyboard device of the present invention will be explained in detail.

As shown in FIG. 4, the rotation mechanism 3ri has a fulcrum 6 that slides back and forth along the recess on the top surface of the keyboard device housing 2, and a stopper portion 5 is provided at the front and rear of each. Grasp with finger heat and lift from the recess on the top surface of the keyboard device housing 2, and move the fulcrum 6 of the rotation mechanism part 3 from one stopper part 5 to the other stopper part 5 along the guide groove part 7 as shown by arrow A. As a result, the key unit portion 1 is moved as shown by arrow B through the recess on the upper surface of the keyboard device housing 2. After the fulcrum 6 of the rotation mechanism section 3 reaches the other stopper part 5, the key unit section 1 is rotated as shown by the arrow C and fitted into the recess on the upper surface of the keyboard device housing 2. As a result, the operation surface of the key unit l can be changed from the key arrangement shown in FIG. 2 to the key arrangement shown in FIG. 3, for example. At this time, one stopper part 5
Since a switch 4 for identifying the operating surface is provided near the switch 4, the selected operating surface can be easily known.

〔Effect of the invention〕

As explained above, the present invention provides two different types of operation surfaces on the keyboard device l housing, in other words, each different operation surface is mounted on the front and back of the key unit part 1 shown in FIG. 1, respectively. Since the keyboard is flipped over so that one operation surface can be used, it not only offers a user-friendly device, but also allows for unique keyboard layouts to be used depending on usage and input formats. It is possible to provide a keyboard with enhanced functionality, and this has the effect of reducing the complexity of programs.
