A cap-shaped retainer 40 has a slit 43 formed therein for insertion of a separation plate, and terminal half-insertion detectors 41 projecting towards terminal fitting insertion chambers 21a of a housing 20. The detectors 41 project individually and are insertable into the lower portions of the respective terminal fitting insertion chambers 21a. The free ends of adjacent detectors 41 are connected to increase the strength thereof. The separation plate is insertable via the slit 43 since the half-insertion detectors 41 are connected beyond the inserted extent thereof.

A photoelectric converting device having a plurality of line sensors, each line sensor having an output line and scanning means for scanning that line sensor. Selection circuit selectably directs a signal from one of the plural output lines to a common output terminal. A reset device resets the common output line to a predetermined level in response to the scanning of the line after the signal has been directed to the common output terminal. The readout may be conducted by scanning the plurality of line sensors by alternatively scanning photoelectric conversion cells from different line sensors.

An image pick-up device which uses a charge transfer type solid state image pick-up device, and further is provided with a shutter so as to form a high quality picture signal in such a manner that smear is prevented by prohibiting the incidence of light on the device while the charge is being transferred in the device. Further, the device is driven by a clock signal for still photographing in order to obtain a high quality picture information for one frame. Further, the photographing parameter is automatically changed over or the monitor is changed over between the motion picture photographing mode and the still photographing mode.
