IPC: B41J31/00
Filed: 1984-02-28
Abstract: PURPOSE:To form the low cost, high reliable ink ribbon capable of preventing mixed color, by a method wherein the portion as the ground not containing ink of which contains ink absorbing liquid is provided at the same portion as the pressing portion of a printing means, or otherwise within a broad range. CONSTITUTION:The portion as the ground not containing ink of which contains ink absorbing liquid is provided at the same portion as the pressing portion of a printing means, or otherwise a broad range. The ribbon is exchanged by the relative movement of a printing head 21 and the ribbon 22. For the use method of the ink ribbon, the ink attached to the wire top of the printing head is transferred onto the ground by always or otherwise, on occasion printing the colorless portion of the ink ribbon when the color tone of the ink is exchanged. Because the colorless portion of the ink ribbon is contained with ink absorbing liquid by coating or impregnation, the ink attached to the wire top can be easily removed by cleaning. Because the mixed color of ink is prevented by thus transferring the ink of the wire top onto the ground portion, a high reliable low cost color printer can be obtained with the power saving dot head of low noise and low cost without decreasing the impact force.

Upon ending of the advance, the fingers 26a, 26b unclamp the work and at the sam time, the work 39 is pressed, and the bars 6a, 6b are retreated. Thence, the clamp 4 moves upward and the fingers 26a, 26b assume a clamping state.

Abstract: PROBLEM TO BE SOLVED: To stably carry a substrate holder by making the open angle of a V-shaped groove in a substrate-support apparatus smaller than the chamfer angle at an inner circumferential part of the center hole of a substrate. SOLUTION: Chamfered parts 34 and 36 are formed on both sides of an inner circumferential part of a center hole 24 of a substrate 10, and the chamfer angle α made by them is 90 degrees. An open angle β of a V-shaped groove 54 of a V-shaped groove block 52 is 30 degrees. In this way, the open angle βof a V-shaped groove 54 is made smaller than the chamfer angle α of the center hole 24, so that the substrate 10 is supported stably in the vertical state by the V-shaped groove 54. Composed to the conventional block having β<α, the V-shaped groove block 52 has improved stability of the substrate 10 against shaking at carriage of the substrate 10. Even if the substrate 10 is carried at a high speed by using a carriage robot, the substrate 10 will not become slanted on the V-shaped groove block 52.
