Title: On-vehicle video tape unit
Inventor: TOGAWA FUMIO
IPC: G11B15/02
Filed: 1989-08-02
Abstract: PURPOSE:To prevent the position of a tape from being changed even when a key interlock power source is repeatedly turned ON/OFF and to start reproducing from a stopped picture by keeping a turned-OFF state even in case that the power source is turned ON when the tape is set in a stopped state and returning the states of the tape and power source to be original when the tape is set in any state excepting for the stopped state. CONSTITUTION:When a key interlock power source 5 is turned OFF by the key of a car during the operation of a video 9, a video control microcomputer 5 stores the operating state of the video to an internal memory and sets the video in the stopped state. When the key is turned OFF, the turned-OFF state of a power supply part 7 is maintained. When a key 2 is turned ON again and the video 9 is set in the stopped state before the power source is turned OFF, the state for the tape position is kept as it is by keeping the turned-OFF state of the power source. In the case of the operating state excepting for the stopped state, the dip of the tape is removed before the power supply part 7 is turned ON and operation is executed. After processing is executed to prevent the tape from being rolled in, the operation is returned to the original operating state. Thus, even when the key of the card is repeatedly turned ON/OFF, the tape position is not changed and reproducing can be started from the position where the video is stopped.

Title: Shape recognizing device
Inventor: SUGIYAMA SHIGERU
IPC: G06K9/00
Filed: 1985-09-10
Abstract: PURPOSE:To recognize an image simultaneously with its input by receiving many light spots as an image of one plane and using an area numbering circuit. CONSTITUTION:Light emitted by a spot light source 20 is made into a parallel light beam 24 by a mirror 21 and passes through a lattice slit 19. The parallel light beam 24 passing through the slit 19 becomes spot light 23, which is projected on a steel plate 22. The slit light 23 is reflected irregularly by the surface of the steel plate 22 and a specific part of the reflected light is inputted to a visual input device 17. The light signal inputted to the device 17 is processed by a signal processor 18. The processor 18 numbers the spot image from the device 17 by the area numbering circuit. Then, projections and recesses of the measured spot image are detected from the position shift between a measured spot image obtained on the basis of a previously given ideal spot image and the inputted measured spot image. Consequently, the shape of the body is recognized. Thus, fast recognition is performed by segmentation using this device.
