摘要： In a thermal head control system for controlling heating energy to a thermal head perforating stencil material unrolled from a stencil material roll, the heating energy to a thermal head is controlled according to the surface condition of the stencil material. The residue of stencil material M in a stencil material roll (21b) is calculated by a residue calculating means (65) and the elapsed time of the stencil material roll from production thereof is obtained on the basis of date data on the date of production of the stencil material roll stored in a storage portion (70) of the stencil material roll (21b) . Further, kind data on the kind of the stencil material stored in the storage portion (70) is obtained and the heating energy is obtained on the basis of the residue, the elapsed time and the kind data. On the basis of this heating energy, the heating action of the thermal head (22) is controlled.

摘要： In a thermal head control method for thermally making a stencil master plate from a thermal stencil master plate sheet in the manner of a dot matrix for each line and forming an independent hole for each dot, a physical quantity representing the temperature of the thermal head (23), such as a time interval (Ti) for the plate making action by the thermal head (23) for each line or a temperature (Te) actually measured from the thermal head (23), is measured before the plate making action of the next line. The measured quantity (Ti,Te) is compared with a prescribed value (Xi,Xe), and if the quantity (Ti,Te) is other than the prescribed value (Xi,Xe), the thermal head (23) is driven (pre-heated) at a power level which is lower than the rated power output and would not affect the thermal stencil master plate sheet. The effective heat emitting property of the thermal head (23) is made uniform without regard to other factors, and a satisfactory perforation is carried out on a thermal stencil master plate sheet at all times.

摘要： A plate making device and method, wherein when a light sensor detects that the stencil plate inserted into the plate making device is provided with the through hole, the controller supplies a current to the thermal head for T1 seconds to control the heat time to be short, so that the perforation energy of the thermal head is reduced. On the other hand, when the light sensor detects that the stencil plate has no through hole, the controller supplies a current to the thermal heat for T2 seconds longer than T1 seconds to control the heat time to be long, so that the perforation energy of the thermal head is increased. In this device, even when any type of stencil plate is used, the plate making process providing the best print quality for each stencil plate can be performed.

摘要： A heat-sensitive stencil master is made by imagewise perforating a heat-sensitive stencil master material by use of a thermal head having a plurality of heater elements which are arranged in a main scanning direction and are respectively energized through discrete electrodes while the stencil master material is fed in a sub-scanning direction. A thermal head in which each of the heater elements is divided into at least two segments which are connected to a common discrete electrode to be energized simultaneously with each other is used and each picture element of the stencil master is formed by two or more small perforations formed by the segments of each heater element.

摘要： A stencil is made by the use of a thermal head which has an array of resistance heater element arranged in a main scanning direction. The resistance heater elements are selectively driven while the stencil material is conveyed in a sub-scanning direction intersecting the main scanning direction so that perforations are formed in the stencil material in a predetermined size at a first pitch in the main scanning direction and a second pitch in the sub-scanning direction. The stencil material is perforated so that unperforated portions which continuously extend in one of the main scanning direction and the sub-scanning direction to separate perforations in the other of the main scanning direction and the sub-scanning direction are left in the stencil material.
