Title: Laser beam scanning position detector
Inventor: ASADA KENICHIRO
IPC: G03G15/04
Filed: 1986-06-17
Abstract: PURPOSE:To accurately detect the laser beam position even if the intensity of a laser beam varies by delaying a signal form a beam detector by a time set in accordance with the intensity of the laser beam. CONSTITUTION:The beam detector 33 outputs a signal having a pulse width corresponding to the intensity of a laser beam. Such an output signal goes through a dely circuit 34 whose delay time is set by a delay time setting circuit 37 corresponding to the detection output from a beam intensity detector 38 that detects the beam intensity beforehand and outputs the said output; after delaying by the said time, the output signal is inputted to a count permission signal generating circuit 35. A counter 36 starts counting by the signal from this circuit 35, and at a time point of the prescribed counting is reached, a print start signal is outputted. With the above-mentioned constitution, the print start timing can be accurately set even if the intensity of the laser beam varies, and as a result, an image excellent in quality can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an audio equipment in which a front panel is not fallen down from the equipment main body even in the case of separating the front panel. SOLUTION: Even when a release button 7 is depressed, a front panel 2 is not completely jumped out of the equipment main body but a claw 15a of an attachment/detachment mechanism section 20 is kept to be locked to a projection of the front panel 2 so as to prevent the front panel 2 from being fallen down. Furthermore, a fitting part consisting of a hinge in a conventional equipment is replaced with a projection 1d and a recessed part 2a integrally formed to a base panel 1c and the front panel 2 of the equipment main body 1. Furthermore, a plate spring having been provided around the middle of the base panel 1c is replaced with a panel popup spring of the attachment/detachment mechanism section 20 and a turning plate energized by the spring. Thus, the component fitted to the equipment main body 1 is only the attachment/detachment mechanism section 20. Thus, assembly man-hours for attachment/detachment are reduced and the space factor of the equipment main body 1 is improved.
