摘要： In an optical reading apparatus having an image sensor (8) for converting optically readable information into an electrical signal, a sensor driving circuit (9) is arranged to produce at least two clocks (φ TG1, φ TG2 ) with which two or more groups of optical imaging elements (8a) of the image sensor are respectively driven. In one emebodiment, the two clocks have a time or phase difference (T 2 . T 3 ) therebetween so that signal charges from one group of the imaging elements are derived at once after signal charges of another group are derived. The derived signal charges are read out in a sequence within a period equal to the time difference. This enables a charging time to be twice or more the time difference providing high sensitivity. Since at least two or more read data can be obtained within a single charging time (T 1 ), high-speed reading is also resulted. In another embodiment, the optical reader is switched so that one of high-speed mode and high-resolution mode is selected. In a further embodiment, the invention is adapted to a reader having an area image sensor (8').

摘要： PURPOSE:To set reading reservation by an optical read means and to attain reservation setting of a broadcast program with simple operation by providing a bar code representing a date of program, a broadcast station and a broadcast start time to a program column on a newspaper or a magazine. CONSTITUTION:A 1st bar code 2 is added to a space of a data column of a program column on a newspaper or a magazine and 2nd bar codes 3-3 are added respectively to a space of each program column of the program column. Then the 1st bar code 2 and one of the 2nd bar codes 3-3 of the program column of a date specifying the broadcast program to be reserved are read by an optical red means 4, a decoding means 5 decodes the content of read and a reservation setting means 6 sets the broadcast station, date and broadcast start time of the reserved broadcast program as a reserved setting data and gives it to a recording means 1a. Thus, the reservation setting is attained and the setting operation is simplified.

摘要： PURPOSE:To recognize the normal/defective condition of a bit of information to be read, by performing the spot display of the bit of information to be read on the information with a spot displaying means provided on a part of the surface of a read sensor via an optical system. CONSTITUTION:An illuminant beam of light from an illumination light source part 2 is projected on a bar code label 1. A bar code image is image-picked up on the read sensor 7 via a lens 5 and a diaphragm member 6. The beams of light from light emitting diodes 8 and 9 provided at both sides of the scanning lines (l) of the read sensor 7 are projected and image-picked up on the bar code label 1 via the diaphragm member 6 and the lens 5. It is possible to recognize the normal/defective condition of the image pickup state of the bar code image based on the image pickup state.

摘要： PURPOSE:To decrease the reading defects of bar codes put on a curved surface by increasing the width of bars set at both sides of a bar code in its width direction compared with a reference value. CONSTITUTION:The width of bars forming two character codes (start and stop codes) (a) set at both ends of a bar code 2 is doubled as much as those bars forming other character codes 0 and 1. In other words, thin black bars and thin spaces are printed in the (2XN) width together with the thick black bars and thick bars printed in the (2XW) width respectively based on the given reference width N of thin bars and the reference width W(=2.5XN) of thick bars. Thus a bar code label 1 is obtained. Such level 1 functions to reduce errors due to a circumferential surface and also to reduce the reading defects with a bar code reader.

摘要： PURPOSE:To make an infrared cut filter unnecessary by utilizing a popular reading sensor and to enable readout of optical information of normal ink and heat- sensitive print by utilizing a red color light emitting diode with high luminance as a light source. CONSTITUTION:A red color light emitting diode 1 having a light emitting spectrum within a range of 650-700nm is used as a light source. With respect to a bar code label 4 printed by a heat sensitive printer, a reader is arranged manually, and the diode 1 is brought into the light-emitted condition. Red color luminance light generated by the emitting illuminates the label 4, and the light intensity due to the reflected light allows a bar code video to be projected in correspondence to a bar code 5 through a lens 7, an optical system of a diaphragm member 8 and an image sensor 9. At this time, when the light emitting spectrum is within the range of 650-700nm, the sensitivity of the sensor 9 is most satisfactory. Thus the use of a standard reading sensor causes an IR cut filter to be unnecessary, and readout of optical information by popular ink and heat sensitive print can be possible.

摘要： PURPOSE:To increase an optical-information readable range of a reader equipped with an electron scanning type read sensor, by making the optical axis of a light irradiating means for irradiation light coincident to the optical axis of reflected light from the optical information in the same plane. CONSTITUTION:The reader held in a hand is disposed at a bar code label 4 printed by a thermal printer and four red diodes 1 and 2 are turned on. Red illumination light passes through a lens 3 and is reflected by a plane reflecting mirror 6 to irradiate the bar code label 4. The bar code videos orthogonal to each bars are image-formed by the light irradiation as a bar video in which the intensity distribution of the light is corresponding to the bar code 5 on the read line on which photoelements of an image sensor 9 are arrayed. At this time, the optical-axis plane of the reflected light is coincident with the optical-axis plane of light reflection, so both optical-axis plane never cross each other and the range of variation in the distance between an opening part facing the level 4 of a band-held case 10 and the label 4 is widened up to the range of the depth of the field of a lens 8.
