A magnetic-tape storage apparatus having a simple structure and being able to surely store magnetic tapes on each of which valuable data are recorded and the recorded data on them at a low cost and over a long period in a small space, a magnetic-tape storage apparatus comprises a housing, a cartridge storage part, a magnetic tape drive, a cartridge transfer device [] to selectively transfer a plurality of cartridges stored in the cartridge storage part to the magnetic tape drive and to return to the original position, a cartridge data reading device to selectively and contactlessly read data retained in each memory chip of the cartridges stored in the cartridge storage part and a computer to control them and to rewind the cartridges timely.

Magnetic-tape storage apparatus

A camera for taking an image of movement of a hand, and a hand pattern switching apparatus which operates an object equipment based on the result of the image taken by the camera, having a storage unit for saving the image taken in the state that a hand does not exist in the image pickup area of the camera, as an initial image data, a differentiation unit for obtaining a difference image data between an original image data that is the image taken in the state that a hand exists in the image pickup area of the camera, and the initial image data, a luminance detection unit for obtaining an average luminance in a place close to a hand based on the image data of a place close to a hand obtained by the differentiation unit, and a processing unit for performing binary processing of the original image data by a threshold value based on the average luminance calculated by the luminance detection unit.

Hand pattern switching apparatus

A hand pattern switch device recognizes a hand pattern from an image of a hand in an image pickup zone and detects a hand motion. One of controlled objects is selected based on the recognized hand pattern and/or hand motion. In accordance with the selected object, a mode of detection of operation information based on hand motion is changed. In a moved distance detecting mode, a moved distance of the hand in the zone is detected as operation information, and in a stop time detecting mode, a stop time of the hand at a stop position to which the hand has been moved in the zone is detected as operation information. The image pickup zone is at a location which is located laterally to a steering wheel and to which a driver can extend his/her arm without changing a driving posture.
