Title: Information input device
IPC: G06F3/0354
Filed: 1992-03-16
Abstract: PURPOSE:To enable an operator to operate a spherical wave input means in the most comfortable posture independently of the arrangement of a contact input means by providing this information input device with an input switching means and an interruption signal forming means. CONSTITUTION:The information input device is provided with the input switching means 3a using the contact input means (keyboard) 3 to switch the validity/invalidity of an input and the interruption signal forming means 6 for generating an interruption signal for validating an input through the input means with a spherical body (track ball) 1.

Title: Device for winding magnetic tape
Inventor: KUBO TOYOHIDE
IPC: G11B23/113
Filed: 1987-03-14
Abstract: PURPOSE:To surely perform the attracting processing of the cut end of a bonding tape and to surely bond a reader tape with a magnetic tape, by moving a reciprocal board forward and backward along an attracting board, adsorbing one side of the bonding tape on the reciprocal board in the forward moving process of the reciprocal board, and attracting the other side of the bonding tape on the attracting board in the backward moving process. CONSTITUTION:The reciprocal board 30 is moved backward in a state where the attracting board 31 attracts the one side of the bonding tape 28. At this time, the reciprocal board 30 does not attract the bonding tape 28. Afterwards, the reciprocal board 30 adsorbs the one side of the bonding tape 28, then, is moved forward. At this time, the attracting board 31 releases the attracting state of the bonding tape 28. By such operation, the tip of the bonding tape 28 is protruded from the tip of the attracting board 31. At this time, since the one side of the bonding tape 28 is attracted on the reciprocal board 30, the bonding tape is prevented from being hung down due to its dead weight. Next, a pressing member 29 is lowered and attracts the upper plane of the bonding tape 28, and in such a state, a cutter 32 is raised, and cuts the tip of the bonding tape 28 at a constant length. A cut bonding tape 28 is carried to the abutting part of the reader tape 2 and the magnetic tape.
