A copier is neither an input device nor an output device because it need not be connected to a computer and usually is not. A Printer, which may also be used as a copier, is an output peripheral device. A Scanner, which feeds data to a computer, is an input peripheral device. Modern digital copiers use scanners as their "front ends". The scanner is then an input device to a copier.

A computer case by itself is not a peripheral as such, nor is it an input or output device. It is just the cabinet that contains the computer system. That said, the components inside fill all of those roles. The case contains the motherboard which is about output, input, and processing.
A serial port is neither strictly an input device nor an output device; rather, it is a communication interface that can handle both input and output data. It allows for the transmission of data between a computer and peripheral devices, such as modems or printers. Depending on the direction of data flow, a serial port can function as an input, output, or both simultaneously.
