Abstract
In a small-sized data terminal apparatus with an image input function, a CCD image sensor inputs an image of an object for photoelectric conversion. A mirror is provided between the CCD image sensor and the object, for reflecting the image of the object to input it into the CCD image sensor. A waveform shaping circuit converts the output signal from the CCD image sensor into a digital signal. A timing pulse generating circuit controls the waveform shaping circuit and the CCD image sensor. A memory circuit stores data. A communication circuit transfers the data to external equipment. A control circuit processes the output signal of the communication circuit and the memory unit. A display circuit displays the output of the control signal. In one embodiment, the CCD sensor is a CCD area image sensor. In another embodiment, a timing detector is used in conjunction with a motor that turns the mirror. In a further embodiment, a timing detector is used in conjunction with a roller which rotates when the data terminal apparatus is manually moved.
