What I teardown is the Fujifilm Instax 210 Instant Camera Black.

INSTAX 210 Camera – With its rounded shape, easy-to-hold side grip, and fingertip controllable composite control panel, the instax 210 offers vivid, high-quality prints almost instantly. Its automatically-adjusting flash, high-resolution retracting lens and big clear viewfinder add up to unsurpassed performance.
Finally we get all the parts, most of which are made of plastic, supplemented by glass and metal. Manufacturing is mainly achieved by injection molding and molds.
The MB89980 series is a line of the general-purpose, single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as an LCD controller/driver, an A/D converter, timers, remote control transmission output, buzzer output, PWM timers, and external interrupts.

I really like the motor drive gear part. When I tore down it, I couldn’t help but feel the human intelligence, it was like a precision mechanical watch, very amazing. I think the designers use different gears to adjust the speed of the film rotation and control the roller to send the photo out, with just one motor and chip to achieve the whole work together.
The other part is the telescopic part of the lens, which is realized by the semi-fixed rotation of the parts, which is very interesting. [At about 36 seconds]
