Input system and recording medium

An input system comprising:

• a plurality of input devices that communicate with a touch panel apparatus and are used to point out positions on a display screen of the touch panel apparatus, wherein
• each of the input devices includes:
• a transmitting unit configured to transmit a status signal representing a contact state of the input device with the display screen;
• a determination unit configured to determine a transmission order of the status signal based on a relationship with other input devices;
• and
• a signal detection unit configured to detect an end of transmission of the status signal from another input device of which the determined transmission order is previous, and
• the touch panel apparatus includes:
• a position detection unit configured to detect a position as an input position of the input device that is a transmission source of the status signal, when the touch panel apparatus receives the status signal representing the contact state of the input device with the display screen and detects a contact of the input device with the display screen.

A non-transitory recording medium readable by a computer in which a computer program for controlling an operation of a plurality of input devices is recorded, in an input system in which a touch panel apparatus having a display screen and the plurality of input devices used to point out positions on the display screen are configured to respectively communicate with each other and detect a contact position of each input devices on the display screen as an input position,

• said computer program executing:
• determining a transmission order of status signals representing a contact state with the display screen based on a relationship with other input devices;
• detecting an end of transmission of the status signals of other input devices of which the determined transmission order is previous;
• and
• starting the transmission of the status signals based on the detection of the end of the transmission of the status signals of other input devices.
