The company announced its most recent iPads around this time last year. The announcement included a smaller version, called the Mini, for the first time.
New iPads would get Apple's latest operating system for mobile devices, iOS 7. The invitation sent Tuesday includes a graphic that mimics the color scheme in iOS 7.
Next Tuesday's event will take place at the Yerba Buena Center for the Arts Theater in San Francisco, a venue Apple has often used in the past.
It follows last month's release of new iPhones with iOS 7 -- the 5S model with a fingerprint sensor and a cheaper, 5C model with a variety of color options.
It's also possible Apple will use the event to release its new Mac operating system, Mavericks. Apple unveiled the system in June. The system will support tagging to help you find files more easily. It also promises better battery life and a way to keep track of passwords across multiple devices more easily. Apple may also announce new Mac computers at the event.
