Abstract
A camera lifting apparatus is used in an industrial vehicle equipped with a cargo handling apparatus for lifting a cargo carrying carriage up and down along a mast provided on a vehicle body. The carriage has a cargo carrying apparatus. The camera lifting apparatus comprises a camera unit attached to the cargo carrying apparatus. The camera unit has a camera for picking up an image of a work area of the cargo carrying apparatus. A moving mechanism moves the camera unit relatively to the cargo carrying apparatus. An actuator drives the moving mechanism.

18. A cargo handling operation aiding apparatus in which a cargo carrying apparatus is provided movable with respect to a vehicle body and which is used in an industrial vehicle that performs plural kinds of cargo carrying works including transportation, characterized in that said cargo handling operation aiding apparatus comprises:
-
a camera for picking up images of image pickup areas of said cargo carrying works;
a moving mechanism for moving said camera to an image pickup position according to a cargo carrying work;
an actuator for driving said moving mechanism;
state detecting means for detecting a working state of the vehicle to discriminate said cargo carrying work; and
a controller for controlling said actuator in such a way that said camera is placed in an image pickup position according to the cargo carrying work which is discriminated based on a result of detection by said state detecting means. - View Dependent Claims (28, 29, 30, 31, 32, 33, 37, 38, 40, 41, 42, 43)

19. A cargo handling operation aiding apparatus for use in an industrial vehicle equipped with a cargo carrying apparatus provided movable with respect to a vehicle body for doing a cargo carrying work, characterized in that said cargo handling operation aiding apparatus comprises:
-
a camera for picking up an image of a work area of said cargo carrying apparatus;
a moving mechanism for supporting said camera in such a manner as to be movable with respect to the vehicle;
an actuator for driving said moving mechanism;
state detecting means for detecting a working state of the vehicle to discriminate the cargo carrying work; and
a controller for controlling said actuator in such a way that said camera is placed in an image pickup position according to the cargo carrying work which is discriminated based on a result of detection by said state detecting means.

20. A cargo handling operation aiding apparatus for use in an industrial vehicle in which a carriage having a cargo carrying apparatus is so provided as to be liftable up and down along a mast, characterized in that said cargo handling operation aiding apparatus comprises:
-
a camera for picking up an image of a work area of said cargo carrying apparatus;
a moving mechanism for supporting said camera in such a manner as to be movable with respect to said carriage;
an actuator for driving said moving mechanism;
state detecting means for detecting a working state of the vehicle to discriminate whether said cargo carrying work is a load pickup work or a load deposition work; and
a controller which controls said actuator in such a way as to place said camera in a storage position where said camera does not project from said carriage when determining based on a result of detection by said state detecting means that said cargo carrying work is the load pickup work, and to place said camera in a position where said camera projects from said carriage to secure an image pickup area without blocking said image pickup area with a load on said cargo carrying apparatus when determining that said cargo carrying work is the load deposition work. - View Dependent Claims (24, 27, 35)

21. A cargo handling operation aiding apparatus for use in an industrial vehicle in which a carriage having a cargo carrying apparatus is so provided as to be liftable up and down along a mast, characterized in that said cargo handling operation aiding apparatus comprises:
-
a camera for picking up an image of a work area of said cargo carrying apparatus;
a lifting mechanism for supporting said camera in such a manner as to be able to lift said camera up and down with respect to said carriage between a storage position where said camera does not project downward from said carriage and a lift-down position where said camera projects downward from said carriage;
an actuator for driving said lifting mechanism;
state detecting means for detecting a working state of the vehicle to discriminate whether said cargo carrying work is a load pickup work or a load deposition work;
height detecting means for detecting a height of said cargo carrying apparatus; and
a controller which controls said actuator in such a way as to place said camera in the storage position when determining based on a result of detection by said height detecting means that the height of said cargo carrying apparatus is less than a threshold value, to place said camera in said storage position when the height of said cargo carrying apparatus is equal to or greater than the threshold value and said controller determines based on a result of detection by said state detecting means that said cargo carrying work is the load pickup work, and to place said camera in said lift-down position when determining based on the result of detection by said height detecting means that said cargo carrying work is the load deposition work. - View Dependent Claims (22, 25, 26, 34, 36)

23. A cargo handling operation aiding apparatus for use in an industrial vehicle in which a carriage having a cargo carrying apparatus is so provided as to be liftable up and down along a mast, characterized in that said cargo handling operation aiding apparatus comprises:
-
a camera for picking up an image of a work area of said cargo carrying apparatus;
a moving mechanism for supporting said camera in such a manner as to be movable with respect to said carriage between a storage position where said camera does not project from said carriage and a projection position where said camera projects from said carriage;
an actuator for driving said moving mechanism;
state detecting means for detecting a working state of the vehicle to discriminate whether said cargo carrying work is a load pickup work or a load deposition work;
approaching detecting means for detecting that said camera has approached a cargo handling target; and
a controller which controls said actuator in such a way as to place said camera in said storage position when said controller determines based on a result of detection by said state detecting means that said cargo carrying work is the load pickup work, to place said camera in said projection position when determining that said cargo carrying work is the load deposition work, and to place said camera in the storage position when determining based on a result of detection by said approaching detecting means that said camera has approached said cargo handling target within a predetermined distance. - View Dependent Claims (39)
