A plant cultivation apparatus includes a lighting device configured to apply artificial light to plants, the lighting device being supported movably in a vertical direction and a height of the lighting device from the plants being adjustable, a projection part projecting from a lateral side of the lighting device, and a light reflector disposed outside the lateral side of the lighting device to reflect light from the lighting device back to the plants, the light reflector including a vertically extending slit that defines a movable range of the lighting device in the vertical direction in which the height of the lighting device from the plants is adjustable.

Hydroponic cultivation system, hydroponic cultivation method, plant cultivation system, and plant cultivation apparatus

A plant cultivation system includes a first floor including a first area having an area provided with a first plant cultivation shelf, an area provided with a second plant cultivation shelf, and an area between the first plant cultivation shelf and the second plant cultivation shelf, the first floor having no air vent holes; a second floor including a second area differing from the first area, the second floor having air vent holes; and an air-conditioning unit configured to circulate air from a ceiling having air supply holes to the air vent holes in the second floor.

Hydroponic cultivation system

A hydroponic cultivation system for plants includes a first plant cultivation apparatus to hydroponically cultivate plants using a first liquid fertilizer, a first supply path to supply the first liquid fertilizer, a second plant cultivation apparatus to hydroponically cultivate plants using a second liquid fertilizer having a component differing from a component of the first liquid fertilizer, a second supply path to supply the second liquid fertilizer, and a tray carrier device to carry cultivation trays with the plants thereon between the first plant cultivation apparatus and the second plant cultivation apparatus. The cultivation trays are arranged in stages and mutually connected in series to the first supply path via a removable hose in the first plant cultivation apparatus, and the cultivation trays are arranged in stages and mutually connected in series to the second supply path via a removable hose in the second plant cultivation apparatus.

Hydroponic cultivation method

The apparatus reads an original by an image reader, and if it recognizes caption(s) included in the original, stores a page number of the original into a memory, thereafter, performs copying based on the stored page number such that the original page including the caption is transferred onto the front side of a recording sheet.

Image forming apparatus

An image processor rotates an image in conformity with the orientation of an original, thereby enhancing user convenience. An original conveyed by an automatic conveyance device is read by an image reader and the image is stored in an image memory. A character in the stored image is subsequently recognized by a character recognition unit and the orientation of the character is discriminated. The image is rotated by an image editor in conformity with a stapling position, and the rotated image is recorded by an image recording unit. Sheets of paper on which images are recorded are stapled at the stapling position by a staple provided in a sorter.

A method and apparatus for recognizing character information in an original document with high recognition accuracy regardless of the size of a character to be recognized. An input image is processed by an image processing circuit and stored in an image recording unit. A character region in the recorded image data is detected by a recognition section, and the image corresponding to the detected character region is read with a predetermined magnification. Character recognition is performed on the image of the character region read at the predetermined magnification, in the recognition section. If the recognition accuracy does not satisfy a predetermined criterion, the same image is read again with a modified magnification wherein the magnification is determined on the basis of preset sizes and the size of the character pattern of a character to be recognized. The image obtained in this way is subjected again to character recognition processing until the recognition accuracy satisfies the predetermined criterion. A character pattern corresponding to the recognized character is generated, and recorded together with the image recorded in the image recording unit in an image recording section. Thus, an image is read with a magnification optimized depending on a character size of an original document image and on a recognition accuracy.

Method and apparatus for recognizing character information at a variable

An image forming apparatus having a timer function includes a main switch for manually switching between supply and interruption of electric power to the apparatus, a detector for detecting whether the main switch is in a power-interruption state or in a power-supply state, a memory for storing a state indicating that the main switch is in a power-interruption state when it has been detected that the main switch is in a power-interruption state, a controller for placing the apparatus in a standby state in which an image can be formed or in a shutdown state in which an image cannot be formed during a preset time period, and a power supply for supplying power to the controller, wherein the apparatus is placed in a standby state even by a set shutdown time period in the case a power-interruption state is stored and wherein the apparatus is placed in a shutdown state during the set shutdown time period in the case the power-interruption state is not stored.
