ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an input device for an injection molding machine having an input touch panel fitted over a screen of a display device.
2. Description of the Related Art
Conventionally, as an input device for an injection molding machine, there has been known a touch type input device for an injection molding machine as disclosed in Japanese Unexamined Patent Publication (Kokai) No. Heisei 2(1990)-103114. With such touch type input device, all input operation can be performed through an input touch panel fitted over a screen of a display device.
On the other hand, as another example of the conventional input device, in which the touch type input device is applied, there has been known an input device
50
, in which the touch type input device is combined with an independently provided switch panel as illustrated in
FIGS. 5 and 6
.
The shown input device
50
includes a first input device
50
a
and a second input device
50
b
. The first input device
50
a
includes an input touch panel
52
fitted over a screen
51
v
of a display device. The first input device
50
a
is designed such that various key pattern portions
53
a
,
53
b
,
53
c
, . . . displayed on the screen
51
v
as shown in
FIG. 6
may be selected for touching by a finger, and then, the XY coordinates of the touched position on the input touch panel
52
are detected by a not shown controller.
In the case of the injection molding machine, there are a wide variety of items to be set, such as pressure, speed, position, temperature and so forth. A ten key portion
54
, commonly used for setting various molding conditions and so forth, a function key portion
55
, including a screen selector key and so forth; and a cursor key portion
56
; are provided in another independent switch panel
57
formed with a membrane sheet switch or so forth. This switch panel
57
, is arranged at an adjacent position to the screen
51
V to constitute the second input device
50
b.
However, in such input device
50
, since the second input device
50
b
formed with the switch panel
57
in addition to the first input device
50
a
, cost is inherently risen for necessity of use of the switch panel
57
of membrane sheet switch or so forth. Furthermore, since the number and layout of the key switches in the switch panel
57
is fixed, addition and deletion of the key and/or modification of the key switch layout is not possible to cause a problem in poor general applicability and evolvability. In addition, while the input touch panel
52
of the first input device
50
a
requires only soft toughing for input, the switch panel
57
of the second switch device
50
b
requires depression with relatively large force to cause different touching feeling in operation to degrade operation feeling.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an input device for an injection molding machine which can make the separate switch panel, such as membrane sheet switch or the like unnecessary to realize significant reduction of cost.
Another object of the present invention is to provide an input device for an injection molding machine which can provide uniform key touching feeling over all keys in operation and thus improve operation feeling in use.
In order to accomplish the foregoing object, an input device for an injection molding machine, according to the present invention, having an input touch panel fitted over a display screen, comprises a panel extension portion extended from the input touch panel and located out of the display screen, and at least one key portion having at least specific key, the at least one key portion being displayed on the panel extension portion.
By this, in the panel extension portion to be a part of the input touch panel, a ten-key portion, a function key portion and a cursor key portion are provided. Therefore, it becomes unnecessary to provide a separate switch panel, such as a membrane sheet switch or the like. Also, since the ten-key portion, the function key portion and cursor key portion can be displayed by printing or so forth, addition, deletion of keys and modification of layout can be facilitated.
