<p><P>PROBLEM TO BE SOLVED: To solve such a problem that the shape of a flexible connecting member (FPC) for connecting a moving head to a control board is complicate to result in cost increase, and that the exposure of a liquid crystal shutter (LCS) for controlling an exposure amount becomes irregular depending on an arrangement position of a temperature sensor, thereby bringing about light and shade of printing and worsening the appearance of images. <P>SOLUTION: A glass substrate 4a which constitutes the LCS 4 has an LED wiring line 10 for connecting an LED 2a and the FPC 5a. The LED 2a connects an LED-attached FPC 5b of a separate body from the main FPC 5a to the LED wiring line 10. The LCS 4 has the temperature sensor 11, and the glass substrate 4a has a temperature sensor wiring line 12 for connecting the temperature sensor 11 and the main FPC 5a. The temperature sensor 11 connects a temperature sensor-attached FPC 5c to the temperature sensor wiring line 12. The LED-attached FPC 5b is arranged at one end in a longitudinal direction of the LCS 4, and the temperature sensor-attached FPC 5c is arranged at the other end in the longitudinal direction of the LCS 4. The shape of the FPC is simplified, and a take number of products is increased to reduce costs. The temperature sensor is set at a position away from both an IC for driving a liquid crystal cell and the LED, and therefore the exposure is prevented from being irregular. Beautiful images without light and shade in printing can be obtained accordingly. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
