Title: Thermal head
Inventor: TANAKA HIDEFUMI
IPC: B41J2/335
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To obtain an appropriate heat generation pattern in accordance with an amount of a current supplied to a heat-generating resistor by setting to the heat-generating resistance body formed on a substrate grooves for dividing the heat-generating resistor almost equally to three and forming the substrate of a glass member. SOLUTION: Electrodes 4A are set at both ends of a heat-generating resistor 4B, and two slim grooves are formed in a direction connecting the electrodes 4A, thereby dividing the resistor 4B to three in the same direction. These electrodes 4A and resistor 4B are formed to a substrate of a glass member. Right and left divided pieces of the resistor 4B generate heat less when an amount of an electricity supplied to the electrodes 4A is small, whereas a central divided piece generates heat more than the right and left divided pieces. Only the central divided piece generates heat in a slim elliptical shape, thus facilitating low-density printing.  When the amount of the supplied electricity is middle, a heat generation part of the elliptical shape generated at the center becomes large in size and also the right and left divided pieces form heat generation parts of a slim elliptical shape, so that a part where the ink is transferred is not noticeable.

Abstract: PURPOSE:To compensate a decrease in illuminance on a screen and at an exposure part during high-magnification projection without increasing electric power supplied to a light source by providing a moving mechanism which move the front-group and rear-group lenses of a condenser lens independently. CONSTITUTION:A driving disk 46 rotated by a motor 47 moves a front-group lever 25 and a rear-group lever 35 independently to move only the rear-group lens 4b while fixing the front-group lens 4a up to specific magnifications, e.g. 15 times magnification or to move only the front-group lens 4a while fixing the rear-group lens 4b at a 15 times magnification projection position for projection magnifications which exceed 15 times magnification. Therefore, when a projection state of <=15 times magnification is changed to a projection state of <=15 times high magnification, the rear-group lens 4b is moved to the 15 times magnification position firstly and then the front-group lens 4a is moved to a desired magnification position. Thus, a decrease in illuminance with high magnification is prevented.
