Title: Laser beam printer
Inventor: SATO YUKIO
IPC: G03G15/04
Filed: 1986-01-10
Abstract: PURPOSE:To greatly suppress current capacity and to shorten the startup by plural scanning systems by providing a startup control means which starts up the plural scanning systems in order at specific intervals of time and a potential measurement control means which measures the surface potential of a photosensitive body successively at specific intervals of time simultaneously with said startup. CONSTITUTION:The photosensitive drum 11 is charged electrostatically by a before- transfer charger 12 to a surface potential VD2 and an APC 14 sends out reference driving current data to the D/A converter 15b of a laser driver circuit 15a at an exposure point A. Then, a reference driving current I0 is applied to a semiconductor laser 15c to irradiate the photosensitive drum 11 with laser light 17. Then, it is decided whether or not an adjusting circuit N reaches the specific number (a) of times and when not, it is decided whether or not the photosensitive drum 11 reaches a potential measurement point B, namely, the printer is held in a stand-by state until surface potential measurement timing is reaches. The surface potential of a potential sensor 18 is detected at the timing and the output of the potential sensor 18 is converted by the A/D converter 19a of a potential measuring instrument 19 into a digital value, which is further converted by a microcomputer 19b into table data.

Abstract: PURPOSE:To facilitate an easy adjustment of change of a resonance frequency when a cartridge is exchanged, by incorporating a conductor into a pickup cartridge casing provided in a resonator. CONSTITUTION:A screw hole is provided at a casing part of a pickup cartridge 1 provided within a resonator 9, and a conductor 7 is put into the screw hole.

If the resonance frequency is higher than the optimum level, the conductor 7 is shifted in the direction L. In such a way, the resonance frequency including a cartridge can be easily controlled. Therefore, the resonance frequency is easily adjusted when a cartridge is exchanged.
