  By the way, as shown in FIG. 4, the component mounting apparatus 3 is a large-sized apparatus arrange | positioned in the intermediate | middle position of a board | substrate unit production line. In order to switch the switching board 33 in order to switch the priority of the input operation on the sub-operation panel 32), in some cases, the operator may have to go around the board unit production line and move to the opposite side. .

  This is because both the main operation panel 31 and the sub operation panel 32 are set so that only one-to-one connection with the CPU 25 is possible, but a plurality of operation panels are connected to the CPU 25. In addition, in order to be able to perform an input operation preferentially from an arbitrarily selected operation panel, it is necessary to configure a separate circuit, and there is a problem that wiring is complicated.

  An object of the present invention is to select an operation from an arbitrary touch panel or all touch panels using a function of the touch panel itself by connecting a plurality of touch panels to one host device in view of the above-described conventional situation. It is to provide an attached touch panel and a component mounting device including the same.

Below, the structure of the touchscreen with an operation selection function concerning this invention and a component mounting apparatus provided with the same is described.
First, the touch panel with an operation selection function according to the first invention is configured to include a switch and priority setting means for setting the priority of input operation to the own device when an ON signal of the switch is input. The

The switch is, for example, a switch composed of an open / close contact.
In the touch panel with an operation selection function, for example, when the signal input from the switch is on, the priority setting means transmits the touch coordinate signal of the touch panel of the own device as a position signal to the host side. When the signal input from the switch is off, the touch coordinate signal of the touch panel of the device itself is not output, and the position signal from the lower operation panel is transmitted as it is to the host side.

In addition, the touch panel with an operation selection function is configured to be, for example, any one of a plurality of units connected to the central control unit.
Next, the component mounting apparatus of 2nd invention is comprised including said touch panel with a display apparatus.

  According to the present invention, since the priority of the input operation of the own device can be set by the touch panel itself, any one touch panel can be selected from a plurality of touch panels connected to the central control device, and the priority of the operation priority can be selected. This makes it easy to make settings, which makes it easier for the operator to perform input operations on a system having a plurality of touch panels.

  Also, even in a system with multiple touch panels connected, it is not necessary to provide a special circuit configuration between the multiple touch panels, and the operation priority of the device itself can be set only with the touch panel body, making the configuration simple and inexpensive. System can be constructed.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a system block diagram of a component mounting apparatus equipped with an operation panel of the present invention. As shown in the figure, the component mounting apparatus 35 of this example includes a CPU 36 and the same I / F 26, memory 27, VGA 28, etc. as those of FIG. 7 connected to the CPU 36 via a bus. . The configurations and functions of the I / F 26, the memory 27, and the VGA 28 are the same as those in FIG.

  In this example, the two operation panels 37 (37a, 37b) shown in FIG. 1 having the same external configuration as the operation input display device 10 shown in FIG. The configuration and function are different from those of the operation panels (the main operation panel 31 and the sub operation panel 32) described in FIG.

  That is, first, the switching board 33 in the case of FIG. 7 is not interposed between the two operation panels 37 of this example. The operation panel 37 of this example can switch whether or not an input operation can be performed by itself without the switching board 33 as in FIG.

  In this case as well, the entire device comprising the display screen of the display device, the touch panel sheet deposited on the display screen, and the control unit for driving and controlling the display screen and the touch panel is collectively referred to as an “operation panel”. It is out.

  FIG. 2 is a configuration block diagram of the operation panel 37. As shown in the figure, the operation panel 37 includes a monitor & touch panel unit 38, at least an image signal processing circuit 39, and a position signal processing circuit 40. The operation panel 37 includes a selection switch including an open / close contact, although not particularly illustrated.

  The image signal processing circuit 39 includes a VGA input circuit and a VGA output circuit. The image signal processing circuit 39 receives an image signal processed from an image pickup signal of a camera and an image signal of a display screen of a host device such as a personal computer.

  The image signal processing circuit 39 displays the image signals input from the outside on the display screen of the monitor & touch panel unit 38 and outputs the image signals to the lower operation panel 37.

For example, when the operation panel 37 of FIG. 2 is the operation panel 37a shown in FIG. 1, the lower operation panel 37 is the operation panel 37b shown in FIG.
The position signal processing circuit 40 includes an RS-232C input circuit and an output circuit as an interface with an external device.

  The position signal processing circuit 40 receives a position signal by an input operation to the touch panel of the monitor & touch panel unit 38 from the inside, and is a touch coordinate signal of the touch panel from the host side or a lower operation panel 37 from the outside. Position signal is input.

  Further, the position signal processing circuit 40 is inputted with an open / close signal of the contact of the selection switch. The position signal processing circuit 40 selectively outputs a signal to be transmitted to the host side based on the contact opening / closing signal input from the selection switch.

  That is, when the contact signal input from the selection switch is ON, the position signal processing circuit 40 transmits the touch coordinate signal of the touch panel of its own device to the host side as the position signal, and the position signal from the lower operation panel 37. Ignore the information.

  On the other hand, when the contact signal input from the selection switch is OFF, the position signal processing circuit 40 does not output the touch coordinate signal of the touch panel of its own device, and the position signal from the lower operation panel 37 is directly used as the host. To the side.

  However, the position signal processing circuit 40 transmits the processing signal (touch panel control signal) input from the host side to the touch panel of its own device and also transmits it to the lower operation panel 37 side as it is.

  In the configuration of the operation panel 37, when a plurality of component mounting devices 35 are arranged on the board unit production line, the operation panels 37 of the component mounting devices 35 can be connected in a daisy chain.

  In that case, the image signal and the touch panel control signal from the host device (for example, the host computer that manages the production line) are input to the first operation panel, and the subsequent operation panel is connected in a daisy chain from the output of the previous operation panel. It is transmitted sequentially.

  The input operation to the touch panel of the monitor & touch panel unit 38 can accept an operation only from one selected operation panel or a plurality of operation panels according to an arbitrary setting.

  As described above, according to the present invention, the operation selection function is held in the operation panel alone, and the function of transmitting the position signal of the touch panel to the upper terminal is transmitted. The operation panel itself has a function of selecting and executing whether to transmit a position signal. Thereby, an easy connection method for connecting a plurality of operation panels and an easy operation panel selection function can be provided.

  FIG. 3 is a diagram illustrating a configuration example of a multiple operation panel system including the operation panel of the present invention. As shown in the figure, in this multiple operation panel system, a plurality of operation panels a37-1, b37-2, c37-3,... ing.

The host device 41 is connected to the operation panel a37-1 by a position signal 42-1 and an image signal 43-1.
The operation panel a37-1 is connected to the operation panel b37-2 by a position signal 42-2 and an image signal 43-2.

Similarly, the operation panel b37-2 and the operation panel c37-3 are also connected by a position signal 42-3 and an image signal 43-3. The same applies to subsequent operation panels.
Further, the selection switch 44-1 is connected to the operation panel a37-1, the selection switch 44-2 is connected to the operation panel b37-2, and the selection switch 44-3 is connected to the operation panel c37-3. Yes. The same applies to subsequent operation panels.

  Operation of the operation panel 37 (37-1, 37-2, 37-3,...) Alone is an image signal 43 (43-1, 43-2,...) From a host terminal (including the host device 41). ) And is displayed on the display screen of the monitor & touch panel unit 38. The image signal is branched and transmitted to the lower terminal.

  The touch panel operation of the operation panel 37 alone transmits the position information of the touch panel operation of the own device to the upper terminal according to the contact state of the selection switch 44 (44-1, 44-2, ...) of each operation panel 37, Ignore location information from lower terminals. Alternatively, the position information of the touch panel operation of the own device is ignored, and the position information from the lower terminal is transmitted to the upper terminal.

  As a result, a plurality of operation panels 37 connected to one host device 41 can be operated by any operation panel 37 by operating the selection switch 44 connected to the own device from the outside. To.

  In this way, the operation selection function for a plurality of operation panels can be realized by a single operation panel, and the number of operation panels to be connected can be increased almost infinitely.
