摘要： PURPOSE:To enable application to KANJI (Chinese characters) by making feeding speed of business forms without changing scan pitch of a line sensor in the direction of a row of characters in a scanner section for English, numerals and KANA letters (Japanese syllabary). CONSTITUTION:Light is irradiated by a light source 1 on a row of characters in a business form in which characters are written. Reflected light is received by a line sensor 3, and character pattern for one stroke in the direction of the row of characters is operated at scan density of 8/mm. and taken in a memory 6 through a photoelectric converting circuit 5. Then, a business form feeding mechanism 4 is driven to make it scan density 16/mm., and the character pattern information for next one stroke is taken in the memory 6 by similar procedure. By repeating the same procedure, the character pattern for a row of characters or a business form is taken in the memory 6.

摘要： PURPOSE: To avoid the regular reflection and to improve the intensity of illumination, by illuminating a surface to be irradiated with a planar light source which is formed with the luminous flux given from a light beam radiating aperture part and at the same time providing a diffusing/reflecting surface at the opposite side to the light source centering on a normal line of the surface to be irradiated and approximately in parallel to the normal line.
CONSTITUTION: A point P on a surface 62 to be irradiated is illuminated by a planar light source 61 like a fluorescent lamp having an aperture part ML. A diffusing/reflecting surface 63 is set at the side opposite to the light source 61 centering on a normal line PQ at the point P and approximately in parallel to the line PQ. Then the point P is irradiated by the diffused and reflected light. An angle ϕ formed by an end M of the part ML and the line PQ is set larger than an incident angle obtained when the regular reflection is produced at the point P. In addition, it is avoided for the outer tube of the fluorescent lamp 61 to come over the luminous flux SS' of the reflected light at the point P. The regular reflection is produced at a small recess on the paper due to a ball pen, etc. This improves the luminous intensity at the point P, and at the same time the regular reflection is avoided at the point P to ensure an accurate photoelectric conversion.

摘要： PURPOSE:To obtain an optical character reader provided with a semiconductor sensor which can read fields composed of a plural lines in an optional order, by storing all field data on a slip to be read in a memory. CONSTITUTION:When a slip 1 to be read starts by sending a start signal from a control section 10 to a carriage and when it is detected that the slip 1 reaches the first scanning line 7, binary coded signals from a binary circuit 20 are stored in a memory 21. In this way, binary coded signals of each field are successively stored. Then, the control section 10 reads out coordinates of fields to be read according to the previously programed order, and calculates addresses of a pattern memory 21. After making above-mentioned procedure, the control section 10 reads out memory patterns, delivers the read out patterns to a recognizing circuit 22, and then, sets the recognized results to a buffer. When this procedure is repeated, only a plural number of fields to be read is recognized successively.

摘要： PURPOSE:To decrease the tracking shift due to the temperature change of monostable multivibrator delay amount and due to the time aging, at long playing, by triggering the delay monostable multivibrator with the head switching signal at the servo circuit. CONSTITUTION:The head switching signal 15 is input to the phase comparator 10 and triggers the delay multivibrator 28. The delay output 29 of the delay monostable multivibrator 28 is input to the switch 6 together with the frequency division output 3, and at the standard play SP with the switch 6, the frequency output 3 is selected and at the long playing LP, the delay output 29 is selected, for output. In this case, the drum servo system 27 is controller so that the frequency division output 3 and the head switching signal 15 can always be synchronized, and the duty of the head switching signal 15 is 50% at all times. The delay monostable multivibrator 28 is triggered with the leading phase of the head switching signal 15 and the amount of delay can be small. Accordingly, the amount of delay by the monostable multivibrator at LP is a half or less as compared with conventional amount, allowing to sufficiently decrease the tracking shift due to the temperature change and time aging change.

摘要： PURPOSE:To reduce a shift in tracking due to temperature variation and aging variation at long play by triggering a delay monostable multivibrator by a vertical synchronizing signal in a next period after a dividing monostable multivibrator is triggered. CONSTITUTION:Vertical synchronizing signal 1 changes into division output 3 through dividing monostable multivibrator 2. On the other hand, output 29 with synchronizing pulse 1b sampled by gate 28 is inputted to switch circuit 6 together with division output 3. The output of switch circuit 6 is passed through a recording amplfier to record control pulses 9 and 9' on a magnetic tape. Then, division output 3 is supplied to drum sero-system 27 to perform phase control. At this time, the synchronizing pulse triggering delay monostable multivibrator 4 is pulse 1b in a next period when dividing monostable multivibrator 2 is triggered, so that delay value t' for obtaining control pulse 9' at long play will lessen.
