A camera system has a camera section, a reproduction section and a printer section, the printer section being separably attachable to either the camera section or the reproduction section to form an integral body. The camera system has photoelectric conversion elements and picks up an image of an object to produce image data. The reproduction section processes the image data so as to reproduce the picked-up image on a display screen, and the printer section prints the picked-up image on printing paper based on the image data. The reproduction section may include an output device which transmits the processed image data to a television set having a display screen, and it may also be integrally provided with a monitor having a display screen. The camera system further includes a recording portion electrically connected with the camera section and which records the image data. The recording portion has a first recorder which records the image data in an internal memory built in one or each of the camera section, the reproduction section and the printer section, and a second recorder which records the image data in an external memory removably mountable on one or each of the camera section, the reproduction section and the printer section.

A thermal printer has detachably attached to a frame assembly of a printer a print unit having a built-in thermal head. The print unit accommodates therein an inked ribbon. By a drive member installed within the frame assembly, the thermal head is pressed against the platen roller and consequently driven thereby. The print unit is provided with a unit case and a cover allowed to be opened or shut relative to the unit case. The inked ribbon can be attached to or detached from the interior of the unit case. The unit is capable of incorporating the platen roller therein. In this case, the opening of the cover induces formation of an opening between the platen roller and the thermal head. The unit incorporating the platen roller therein is not required to be provided in the frame assembly thereof with the drive member which would cause the thermal head to be pressed against the platen roller by virtue of a spring member and and consequently induce a displacement of the thermal head. The use of a roll of thermosensitive recording paper in the unit obviates the necessity for the inked ribbon.

A thermal transfer recording device for recording an image on a recording sheet by means of an ink film. The device has a cassette accommodating recording sheets and a unit accommodating an ink film both of which are loadable into the main body of the device, and further has a first sensor for detecting the type of the cassette and a second sensor for detecting the type of the unit. The device alerts the operator when the type of the unit is judged to be incompatible with the type of the cassette according to the result of detection by the first and second sensors.

Thermal transfer recording device

A paper feeding device which extracts from a cassette accommodating a stack of sheets such sheets one at a time and feeds them to the next step, namely an image forming part, comprises an attracting member capable of being moved between an attracting position at which the attracting member attracts a sheet from within the cassette and a feeding position which lies above the attracting position, a pressing roller capable of being moved between a position of retraction and the feeding position, and a rotary roller capable of cooperating with the pressing roller in nipping the sheet at the feeding position. The pressing roller moves to the feeding position after the elapse of a prescribed time following the completion of the motion of the sheet by the attracting member to the feeding position. The rotary roller is rotatably set in place at the feeding position. The rotary roller may be attached to the attracting member in such a manner as to be moved vertically in both directions in conjunction with the attracting member. When the leading end of the sheet being conveyed by the attracting member from the attracting position to the feeding position comes into contact with the pressing roller held at the position of retraction, the pressing roller acts upon the sheet in the direction of returning the sheet to the cassette.

An image forming apparatus for forming images on a roll of recording material, comprising a case accommodating the roll of recording material which is drawn out therefrom. A movable member is disposed within the case and is movable in accordance with the decrease of the radius of the roll. A detectable member attached to the movable member and a detecting member provided outside of the case are for detecting that the detectable member has been brought to a predetermined position by the movement of the movable member when the radius of the roll has reached a predetermined value. The movable member has a length permitting the forward end of the member to move away from the outermost surface of the roll when the radius of the roll has reached the predetermined value.
