A carriage conveying apparatus has a loaded carriage to be conveyed, and a driving vehicle for coupling, towing and conveying the carriage from below the carriage. Since the vertical load of the carriage is transmitted to the driving vehicle, controlled to a proper magnitude, the driving vehicle may be reduced in size and weight, and it is also possible to have stable travel if the carriage is empty. By designing all three wheels so as to be driven and steered, sideways and spin-turn motions are realized. By providing recognition marks and detecting means, it is possible to position the driving vehicle accurately if the setting position of the carriage deviates.

A cartridge to be inserted into a drive unit includes a casing containing a recording medium disc to be driven by the drive unit. The disc has a hub fixed at its center. Center windows are provided at opposite sides of the casing and allow the hub to be inserted therethrough. Head windows are provided also at opposite sides of the casing and allow a reading head to access information recorded on opposite sides of the disc. Shutters are provided around the center windows and normally cover the head windows. These shutters are rotatable about the center windows and uncover the head windows when the cartridge is inserted into the drive unit. An actuator for rotating the shutters is provided between the shutters and the outside of the casing. The actuator has a portion exposed to the outside of the casing so that the shutters are automatically and indirectly rotated by an external force applied to the actuator when the cartridge is inserted into the drive unit. An advantage of the arrangement of these elements is that damage to and malfunctioning of the cartridge is prevented.

A photographic apparatus for producing a visible image on a photosensitive nit including a photosensitive film mounted on a film mount. The apparatus includes: a first member having a supplying station, an exposure station, a developing station and a fixing station provided on a principal surface thereof; two transfer means, one for transferring the unit from the supplying station to the exposure station and or for transferring the unit from the exposure station to the developing station, and from the developing station to the fixing station; and driving means for driving the two transfer means. A latent image of an original is formed on the film at the exposure station, the latent image is developed at the developing station, and the developed image is fixed at the fixing station. The feature of this apparatus is that the function of holding the unit and guiding it to each of said stations is achieved by the first member, and independently the function of transferring the unit is achieved by the two transfer means, whereby the transfer of the unit from one station to another can be carried out securely without fail, and the mechanism of the apparatus can be simplified.
