## Abstract

A plurality of machines are controlled by respective corresponding numerical controllers. One portable display device is enabled to be connected to one numerical controller selected from the plurality of numerical controllers. The numerical controller which has been selected generates display data by display software in the, numerical controller, based on a key operation performed at the portable display device that is connected to the numerical controller. The portable display device receives the display data generated by the numerical controller, and displays the data on its display.

## Claims

### Claim 1

A display system for a machine, which comprises at least one machine, a controller provided on each machine, and one portable display device capable of being connected to the controllers, and displays, by using the portable display device, display data generated by each controller,
wherein the portable display device includes:
a selection unit for selecting, from the respective controllers provided on the at least one machine, a controller for controlling each of one or more machines to be connected; and
a transmission unit for transmitting a connection request signal to the controller selected by the selection unit,
wherein each controller provided on the machine includes:
a permission signal transmission unit for receiving the connection request signal and transmitting a permission signal for permitting connection of the portable display device;
a display data generation unit for generating the display data to be displayed by the portable display device; and
a display data transmission unit for transmitting the display data to the portable display device, and
wherein the display data generated by the controller selected by the selection unit of the portable display device is displayed on a display of the portable display device.

### Claim 2 (depends on 1)

The display system for a machine according to claim 1, the display system further comprising:
an operation input information transmission unit for transmitting an information signal operated or input by a touch panel or an operation key of the portable display device,
wherein the controller includes a reception unit for receiving a signal from the operation input information transmission unit and controls the machine based on the signal received by the reception unit.

### Claim 3 (depends on 1)

The display system for a machine according to claim 1, wherein the portable display device includes an interface for connecting an external storage unit.

### Claim 4 (depends on 1)

The display system for a machine according to claim 1, wherein the portable display device and the controller exchange the connection request signal by wireless, the permission signal, the display data, and information stored in the external storage unit.

### Claim 5 (depends on 1)

The display system for a machine according to claim 1, wherein the portable display device is a tablet terminal.

### Claim 6 (depends on 1)

The display system for a machine according to claim 1, wherein the machine is any one of an electric discharge machine, an injection molding machine, and a working machine.
