摘要： PURPOSE:To set a proper white level at either of white and black parts. CONSTITUTION:A sample holding circuit 31 is set in a sampling state where a white level signal is outputted in accordance with the change of a picture signal when an analog switch 42 is closed. When the switch 42 is opened, the circuit 31 is set in a holding state where the level of the picture signal inputted at the end of a period of the immediately preceding sampling state. When the position of a reading subject is changed to a white part from a black part, the output of a differentiation circuit 33 has the large positive value. Thus a comparator 34 sends out a set signal S to set a flip-flop 35. As a result, the switch 42 conducts. Meanwhile the output of the circuit 33 has the large negative value when the position of the reading subject is changed to a black part from a white part. Thus the comparator 34 sends out a reset signal R to reset the flip-flop 35. As a result, the switch 42 is cut off.

摘要： PURPOSE:To satisfactorily read the symbols after the light reflected regularly from the symbol surface is made incident on a detection element by resetting a peak holding level by means of the reset signals which are produced for each symbol reading action in the prescribed frequency. CONSTITUTION:A peak holding circuit 20 is connected with a reset circuit 30 which resets the peak holding level with the reset signals produced for each symbol reading action in the prescribed frequency. The output of a synchronizing signal generating circuit 40 which produces the synchronizing signal in response to the start of an electrical scanning operation of an optical image is applied to the circuit 30. Then the peak holding level of the circuit 20 is reset in response to the synchronizing signal. Thus the output signals of a detecting element increase temporarily owing to the regular reflected light and the gain of a variable gain amplifier 10 is extremely reduced. Even under such conditions, the gain of the amplifier 10 can be quickly returned to the value corresponding to the quantity of light received by the detecting element by a resetting action. As a result, the symbols can be satisfactorily read.

摘要： PURPOSE:To surely read a symbol with high accuracy in a wide read range by reducing satisfactorily a light source light on the symbol face. CONSTITUTION:By a second condensing lens 13 of two light beams L1, L2 passing through a light selection and transmission member 12, an image is formed in different positions of a one-dimensional photoelectric converting element 15, and from a distance between these image formation positions, distance information corresponding to a read distance is obtained. Subsequently, based on this distance information, a first condensing lens 2 is displaced along its optical axis, so that a laser light L is reduced enough on the symbol face 8 thereby. In such a way, read of a bar-code can be executed surely and with high accuracy in a wide read range.

摘要： PURPOSE:To enable a protective circuit to absorb surges applied to a semiconductor laser irrespective of their frequencies by a method wherein a diode whose conduction voltage is slightly higher than the oscillation voltage of the semiconductor laser is connected. CONSTITUTION:A Zener diode 2 is connected to a semiconductor laser 1 in parallel, and the laser 1 is driven by an alternate current voltage source 3 through the intermediary of a resistor 4. As the forward breakdown voltage of the semiconductor laser 1 is a hundred volts to several hundred volts, the Zener diode 2 of low yield voltage is used to clip a voltage applied to the semiconductor laser 1, whereby the semiconductor laser 1 can be protected against breakdown. Moreover, the Zener diode 2 functions as a low impedance the same as a conventional diode against a reverse voltage to clip a reverse voltage, so that it can protect the semiconductor laser 1 against a reverse surge voltage. Even if the Zener diode 2 is connected to a drive circuit in which a direct current voltage source 3' is employed in place of the alternate current voltage source 3, the same effect can be realized. When a capacitor is inserted in parallel with a diode, a protective circuit can absorb a surge of frequency higher than the switching frequency of the diode.

摘要： PURPOSE:To align the optical axis of a projection and a photodetection system and to eliminate variation in photodetection efficiency due to variation in the distance to an object by providing a hollow optical passage to the center part of a reflecting means and passing laser light which reaches a scanning means from a light source and laser light which reaches the object from a scanning means to the passage. CONSTITUTION:The reflecting means 4 is positioned very closely to the scanning means 3, the laser light 2 from the light source enters the scanning means 3 through the passage 4a at the center part of the reflecting means, and the laser light after being scanned passes through the passage 4a in the opposite direction from the incident light and reaches the object A. Further, an optical element is so arranged that the laser light which is scattered by striking on the object is reflected by the reflecting means 4 and photodetected by a photodetecting means 5 such as a photoelectric converting element. Consequently, the optical axes of the projection and photodetection systems are aligned without using any half-mirror and the variation in photodetection efficiency with the distance to the object A is eliminated.

摘要： PURPOSE:To obtain clear image by synchronizing plural image sensors with the invalid reading out section of these image sensors to have a common part and synchronizing them with the lighting timing of an illumination light source. CONSTITUTION:Each image sensor 2a-2x is respectively driven by associated image sensor driving circuits 1a-1x. The reference driving circuit 1a associated with the reference image sensor 2a outputs the frame synchronizing signal B of which cycle is the longest and repeats one frame operation by resetting with the aid of it's reset signal D. The reset output terminals of the other driving circuits 1b-1x are connected with the reset output terminal of the reference driving circuit 1a. As the result, the frame synchronizing signal B of each driving circuit 1b-1x agrees with that of the reference driving circuit 1a. Therefore, as the longer cycle than that of their minimum frame synchronizing signal is given to the driving circuits 1b-1x, the time of this cycle is transferred to the invalid picture element section and it illuminates the sensor in this section.
