Title: Memory card
Inventor: TANIYAMA YUKIO
IPC: G06F12/16
Filed: 1980-12-25
Abstract: PURPOSE:To obtain a high-speed memory card which has short wiring length, less rounding of an output waveform, and less reflected waves, by packaging a memory circuit and an error correcting circuit in the same memory card and by applying a card selection signal to the error correcting circuit. CONSTITUTION:Each memory card has a memory circuit 6 and an error correcting circuit 2 packaged together, and a card selecting signal is applied not to a decoder of circuit 6, but to the circuit 2 wire ORed, so that when the selection signal is a 0, the output impedance of the circuit 2 increases. When the selection signal is a 1, the output of a wired OR tristate circuit varies with the input. This constitution shortens wiring between the circuit 6 and circuit 2 as compared with connection with the error correcting circuit by wired OR, and the card selection signal is applied to the circuit 2, so that the apparent wiring of the card 1 is shortened. Further, since the output of the circuit 2 is wire ORed, the rounding of an output waveform and reflected waves are reduced to realize a high- speed operation memory card.

Abstract: PROBLEM TO BE SOLVED: To release freezing in a short period of time without using a heater by conducting electricity by repeating forward and backward rotation of a motor when a control circuit cannot be operated due to freezing of a mirror device. SOLUTION: When a manual switch 28 is turned on, the operation on a protrusion side of a mirror device is started within 2 seconds, and an overcurrent to a motor 11 is detected, CPU 21 in a control circuit 20 gives instructions for the protrusion of the mirror device and the stop of rotation of the motor 11.
