Title: Control method for electronic device and bar code reader
Inventor: ITO MOTOHIKO
IPC: G06K7/10
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To detect the external light that is optimum to the change of the ambient external light by varying the constant which decides the detection level of a detection signal to reduce the sensitivity against the external light as the time when no state shift occurs is increased. SOLUTION: When a power supply is applied to a bar code reader 1, a CPU 16 first initializes the constant value to decide a detection range of the external light. The constant value is set in every state. If a bar code label 7 is not detected for 10 seconds in a state A where a laser beam is turned on in 100% and a motor 4 is driven to revolve a polygon 3, the state A is shifted to a state B where the turn-on/off ratio is reduced down to 50% compared with the state A. If the label 7 is not detected either and the external light is reduced less than the value decided by multiplying the mean value by the constant value (b) in the state B, the wrong detection is judged and 0.1 is subtracted from the value (b). Thus the detection level of the external light is reduced and the detection sensitivity of the external light is also reduced.

IPC: G02B26/10
Filed: 1987-02-23
Abstract: PURPOSE:To prevent fluctuation in the timing for starting outputting of a synchronizing signal by adjusting the posture in the projection direction of a light beam in a light receiving part for modulation control to control the timing for starting the modulation to the light beam. CONSTITUTION:An operating means HM for adjusting the posture in the projection direction of the light beam B of the light receiving part 8 for modulation control provided to control the timing for starting the modulation of the light beam B by detecting the light beam B on the outside of an image forming region on a photosensitive body 7 is provided. The posture of the light receiving part 8 for modulation control can, therefore, be changed in the projection direction of the light beam and the side part on the front side in scanning of the light receiving part 8 for modulation control can be adjusted so as to intersect nearly orthogonal with the scanning direction of the light beam B. The timing for starting outputting the synchronizing signal from the light receiving part 8 for modulation control is, therefore, adjusted to nearly the same timing even if the passage route for the light beam B to be scanned fluctuates in the direction orthogonal with the scanning direction of the light beam B. The fluctuation in the timing for starting outputting the synchronizing signal for controlling the timing for starting the modulation is thereby decreased.

IPC: H04N5/95
Filed: 1991-03-06
Abstract: PURPOSE:To make it possible to record and reproduce a moving picture and a still picture without timing control in continuous mode by setting a main scanning frequency of a probe to one of a positive integral number of horizontal frequency of an image signal and including time required for flybacking the probe into the period of planking of the image signal. CONSTITUTION:Tunnel current flowing between a probe electrode 1 and a conductive substrate 4 is detected by an amplifier 6. The output 'a' of a readout signal is input into a scanning control circuit section 10. An actuator 2 is driven by an LPF 7, a differential amplifier 8, an integrating circuit RC, a driver 9 and reference voltage VREF, thereby controlling the interval between the electrode 1 and the record layer 3 so that it may be constant. Furthermore, when generating an scanning output signal and a write signal from an image input signal, the electrode 1 is main-scanned by the 1/6 frequency of a horizontal synchronizing signal frequency of an image signal so as to match the blanking period of the image signal with the fly-back period of the electrode 1. This construction makes it possible to record and reproduce a moving picture and a still picture continuously without any timing control.
