An ink jet recording apparatus has a movement mechanism for moving a recording head mounted thereon for recording by discharging ink through discharge ports, and a recovery device for recovering or maintaining the discharge condition of the ink through the discharge ports. The recovery device includes a cap for capping the discharge ports, and a pump for causing pressure changes to expel the ink into the cap through the discharge ports, utilizing the movement of the movement mechanism.

A film drive device for a camera in which the film is transported by an electric motor as the drive source, comprises detecting means for detecting that the winding of all the frames of the film is complete, manually operable switching means for forcibly changing over the film to a rewind state, and operation control means for shifting from a film windup state to the film rewind state. The operation control means makes a first operation of shifting to the film rewind state in response to the completion of the winding by the detecting means and a second operation of shifting to the film rewind state by the operation of the switching means different from each other. Therefore, an efficient shifting to the rewind state can be performed.

A motorized drive device for a camera comprising an electric motor and a transmission system operating with selection of at least two speed change ratios. The operation of the motor is controlled in such a way that the time point for the start of output of a stop signal for the motor alters depending on which speed change ratio is selected.

A film transport apparatus having a spool for taking up film as it rotates, a sprocket for pulling the film in engagement with the perforations thereof toward the spool, and a windup drive system for driving the spool or the sprocket. The film transport apparatus is provided with control means for causing the windup drive system to drive both of the spool and the sprocket from the start of an auto-loading until before its termination, and then to drive only the spool at the terminal stage of the auto-loading, and detecting means for detecting that the film is not sent in the terminal stage of the auto-loading.

A camera having film feed detection means the signal of which varies with the rotation of a rotary detection wheel arranged in between a spool and a film cartridge chamber to follow the rewinding movement of the film and a motorized film rewinding device which rewinds the film by means of a motor is provided with change-over means for changing, according to the output of selection means, the period of time before bringing the motor to a stop after the output of the film feed detection means ceases to vary.
