Title: Tool holder
Inventor: HANSU FUERUTOMAN
IPC: B23B31/22
Filed: 1991-12-18
Abstract: PURPOSE: To easily fix a tool holder on a chuck by radially movably providing a fixing element. CONSTITUTION: When a tool holder 5 is moved onto a chuck 2, a ball 9 makes contact with the outer end of a chuck 4, thereby stopping the movement of a sleeve 6 toward a drilling machine. A user manually pressing the tool holder 5 against the top of the chuck 2 thereby moves a housing 14 toward the drilling device, whereby a spring 16 is compressed to allow a ring 11 to reach the position of an opening 8, resulting in the outward movement of the ball 9 and the disposition of the sleeve 6 at the corresponding part of the chuck 2. Next, by lightly turning the housing 14 by hand relative to the drilling machine, for example, the ball 9 can be engaged with a hole 4. Immediately thereafter, a second ring 12 binds the ball 9 in its inward position and locks it with an opening 4.

Title: Embossed code reader
Inventor: TANAKA TERUHIKO
IPC: G06V30/144
Filed: 1992-12-14
Abstract: PURPOSE:To provide an embossed code reader for exactly reading an embossed code regardless of the presence/absence of a hologram seal by providing a read control means for performing reading again while reducing a reading light quantity so as to read the seal part when it is detected that the hologram seal is stuck on the surface of a card. CONSTITUTION:A hologram detection part 18 detects whether the hologram seal is stuck or not from a read detection signal, the quantity of light is suitably switched corresponding to the result and read data after switching at that time are processed by a data switching part 19. In this case, when the hologram seal detection part 18 detects no hologram seal in the case of reading the embossed code, reading is completed once since a CPU 11 can read the surface of the card with the normal quantity of light. When the hologram seal detection part 18 detects it, the embossed code is read by executing the second reading while reducing the reading light quantity since the surface of the card, to which the seal is stuck, can not be read with the normal quantity of light.
