Abstract: PURPOSE:To facilitate proofreading work by supplying and executing en bloc the proofreading jobs of different modes. CONSTITUTION:When a character string is shifted, a mark showing the shift and the shift degree are fed to the head and the end of the part to be shifted while pushing insertion keys. For correction of characters, a new character can be written on an old character.

Title: Thermal head
Inventor: NAKANO KAZUO

Filed: 1981-01-26
Abstract: PURPOSE:To hold good contact state between a heating resistor and a recording paper, by a method wherein a thermal head having a supply conductor and a common supply conductor on the heating resistor surface, the common supply conductor is removed at a position near the end of arrangement of the heating resistors. CONSTITUTION:Gold thin films 16 is not formed on portion 19 of a common supply conductor 4. Recording paper width is usually taken larger so that a heating resistor 1 is prevented from being broken by abnormal temperature rise when electric conduction is carried out at portion without recording paper and heat does not reach the recording paper, therefore width L of the portion 19 is specified to dimension greater than difference between the recording effective width and the recording paper width, that is, increased width of the recording paper. If L is 5mm. or more, level difference according to the gold thin film 16 is absorbed by elasticity of a platen 9, and a thin film 13 of high resistance remains. If many heating resistors 1 exist, much current flows in the common supply conductor 4. Since dimension l is small, horizontal dimension of the portion 19 equals to a half of the width of the common supply conductor 4 or more.
