Abstract: PURPOSE: To permit small vibrations of a rotary box by connecting the bottom wall of the rotary box to the lower end of a vertical spindle by means of a joint having a spherical surface and to prevent damage to a slab by absorbing the vibrations by means of elastic sleeves placed in an intermediate area outside the spindle and on the bottom wall part of the box. CONSTITUTION: When a vertical spindle 6 rotates, a box 12 rotates about a vertical axis 7 and a tube-shaped sleeve 22 rotates about a horizontal axis 18, with a frictional surface 23 producing frictional action on the surface 50 of a stone. When the frictional surface 23 of the tube-shaped sleeve 22 encounters the irregularity of a working surface 50, a horizontal shaft 17 is bent. Thereby vibrations of the box 12 around an intersection point 55 between the radius 54 of the spherical surface 53 of a spherical joint 52 and the vertical axis 7 are produced. Then the small vibrations are absorbed and damped by elastic sleeves 57, 56 arranged respectively between the center area 58 of the spindle 6 and a conical gear 36 and on a screw 11 that secures the bottom wall 51 of the box 12 to a flange 10.

Title: Magnetic card information reader
Inventor: KIBE SHIYOUZOU
IPC: G06K7/00
Filed: 1993-03-23
Abstract: PURPOSE:To exactly read card data by ignoring bit data before a start code recognized as code data and fetching bit data after the start code while recognizing those data as valid data. CONSTITUTION:When an inserted magnetic card 12 is read by a magnetic data reading part 13 and a CPU 14 detects the bit data first showing '1' from the fetched data, it is decided by the CPU 14 whether the fixed number of bit data following these bit data constitute STX signals or not. When it is decided that those data do not constitute the STX signals, the CPU 14 similarly decides whether the bit data in which the '1' is next detected constitute the STX signals or not while setting those data at the top of a bit data sequence. When the data constitute the STX signals, data read after these STX signals are fetched as valid data and these bit data are converted to code data for every fixed number of bits and written in a RAM 16.
