Abstract: PURPOSE:To simultaneously execute both replenishment of new image forming sheets and ejection of image forming sheets already used only by displacing a housing part by collecting the image forming sheet already used into the housing part after all the image forming sheets are used. CONSTITUTION:When almost all of photoreceptive sheets 34 are fed out from the housing part 56 and taken up to a take-up shaft 36 by repeating the execution of an image forming process, a guide plate 57 is detected by a tailing edge detection switch SW1. At such a time, a pressurizing state in a pressurizing part 31 is released to rotate a supply shaft 35 in the direction of an arrow J, so that the photoreceptive sheet 34 already used which is taken up to the take-up shaft 36 is collected into the housing part 56. Since the photoreceptive sheet 34 is collected in the housing part 56 again after all the sheets 45 are used, the photoreceptive sheet already used can be ejected simultaneously with the replenishment of the photoreceptive sheets by displacing the housing part. Thus, the replenishment of the new image forming sheets and the ejection of the image forming sheet already used can be simultaneously executed by displacing the housing part.

Filed: 1992-11-12
Abstract: PURPOSE:To transfer a steel material cut on a surface plate with a surface plate as it is connecting plural gratings in which serrated steel plates and twist bars are arranged in a rectangular framework of serrated steel plate, in the longitudinal direction of the twist bar to form a slat conveyor. CONSTITUTION:Since a grating 2 of serrated steel plates 5 having serrated projections 5c small in contact area with steel plate to be cut is used, it is difficult to cut it with the steel material in the time of cutting. Since an array pitch of the serrated steel plate 5 can be reduced, variation of the steel material is small at the time of cutting and a cutting trouble is prevented. The serrated steel plate 5 machined in a sew teeth shape is used for the contact surface with the steel material and the serrated steel plates are connected by a twist bar 6, a contact surface between the steel plate and the surface plate is reduced and slag is melted down smoothly. Further, since the surface plate is transferred by a conveyor, cut-off steel material etc., is recovered easily.

IPC: H02P6/18
Filed: 1993-12-24
Abstract: PURPOSE:To detect a transistor for driving a motor when the transistor is broken by judging whether the motor has stopped and by detecting a motor voltage. CONSTITUTION:When a motor 5 has obtained an ON state, an induced voltage checking voltage during the stop of motor 5 is first supplied from a DC power supply 1. Then, before outputting a motor drive signal, an induced voltage generated from the motor 5 is compared to the induced voltage checking voltage in a comparator, and the motor 5 is judged to be stopped if no induced voltage is detected by checking by CPU. If the motor 5 is judged to be stopped, a motor driving voltage is supplied from the DC power supply 1 and detected by motor voltage detecting means 7. Then, checking by motor voltage judging means 9 is performed before giving a drive signal to a motor driving transistor, and the motor driving transistor is judged to be burnt out when the motor drive voltage has been detected even though the motor 5 is stopped.
