Title: Electrophotographic printer and medium having program for printer driver recorded therein
Inventor: SUZUKI MASATOSHI
IPC: B41J29/50
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To ensure an accurate print position while reducing the amount of memory to be used as a frame buffer by storing a bit map data in the memory along with positional information and then delivering the bit map data for each positional information from the memory to a print section depending on the output from a sheet position sensor. SOLUTION: Upon receiving a print data containing positional information defined by the distance from a host unit to the end of a sheet or a rule, a positional information storing means 5 stores a bit map data obtained by developing the print data along with the positional information. Consequently, a memory capacity corresponding to a print region is consumed. Subsequently, an individual print means 6 delivers the bit map data for each positional information stored by the positional information storing means 5 from the memory 2 to a print section depending on the output from a sheet position sensor. Consequently, printing is performed individually depending on the distance from the end of a sheet or a rule for each bit map data defined by the positional information.

Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To suppress the warping of an LSI and a PCB(printed circuit board) due to the difference in thermal expansion between the LSI and PCB and, at the same time, to make a heavy heat sink fittable to the PCB even when the PCB is thin. SOLUTION: A PCB 4 is fixed to a PCB stiffener 1 and an LSI 3 is fixed to an LSI stiffener 2. Since the stiffeners 1 and 2 are firmly united in one body by screwing the front end sections of the four supporting bars of the LSI stiffener 2 to the PCB stiffener 1, the warping of the stiffeners 1 and 2 is prevented. Therefore, even when the LSI 3 and PCB 4 are soldered after the stiffeners 1 and 2 are united in one body, the soldered portions are not broken. Since the tapped holes 7 of the stiffener 2 can be used at the time of fitting a heat sink to the PCB 4, the heat sink can be fitted to the PCB 4 without hindrance even when the PCB 4 is thin in thickness.
