Abstract: PROBLEM TO BE SOLVED: To enable a light receiver to receive light from a light emitter to be received, without complicating the constitution and increasing cost, even in the case that the distance from the light emitter to the light receiver is relatively long. SOLUTION: This device is equipped with a light emitter which emits light corresponding to drive condition, a drive controller 12 which controls the drive of the light emitter 11 so that it emits light by a prescribed light emission period, a light receiver 13 which is arranged to receive the light emitted by the light emitter 11 and generates a light reception output signal corresponding to the received light, and a light reception output processor 14 which takes out the light reception output signal obtained from the light receiver 13 by the period corresponding to the light emission period pertaining to the light emitter 11 and forms a light detection signal corresponding to the taken-out light reception output signal.

Abstract: PURPOSE:To prevent the inclusion of an ink ribbon to a platen positively when printing paper is taken off by moving the ink ribbon in a fixed quantity and separating the ink ribbon from printing paper before printing paper printed is taken off. CONSTITUTION:After a printing is completed, the head position of a thermal head 70 is lowered up to a head position 1, a drive reel base for winding is driven, and only an ink ribbon 86 is wound for a constant time in specified length (such as 200 millisecond and 4-5mm). The ink ribbon 86 and printing paper 8 are brought to a positively separate state, the thermal head 70 is returned to the head position again, and taking-off operation is conducted, thus surely preventing the inclusion of the ink ribbon 86.

Abstract: PURPOSE:To enable a block copy for each color to be formed securely using effective off-image information when a color image is printed using block copies of different colors by providing a means to record effective off-image information such as registering marks and color identification marks required for plate making on a conventional printer. CONSTITUTION:At a starting point for respective printing actions, firstly it is checked whether registering marks 81, 84 and color identification marks 91, 92 are correctly obtained as effective off-image data, and then the effective off-image data is set in a RAM, After this, the data is read and printed. If printing of a prearranged mark is completed, it is checked whether the mark printed at present is located on the printing start side or end side. That is, when the marks 81, 82, 91 are printed on a bland part 11, an effective image 10 is printed, and if this printing is completed, the printing of the marks 83, 84, 92 is executed on a blank part 112. When it is judged that the mark printed is not the one at the printing start side, all the printing action is to be ended assuming that said mark is the one printed on the blank 112. Thus four block copies of Y, C, M, B can be produced, and also the registering marks or color identification marks can be automatically printed at prearranged positions.

Abstract: PURPOSE:To decrease the influence of an ink-ribbon driving system on a printing picture by providing a D.C. motor to the driving system of an ink-ribbon winding mechanism and by driving the said motor with a signal delayed to a control signal for platen for a specified length of time. CONSTITUTION:When printing, the control signal SMP is supplied to an input terminal at every constant period T. During the latter half of the period T, the picture elements of 1-line share are printed by a thermal head. Also, the said control signal is inputted to a stepping motor control circuit 2 as well as to a phase shift circuit 4. From the circuit 4, a pulse that rises delaying by t1 is obtained and further by the second phase shift circuit 5, a pulse whose width is t2 is obtained. This pulse is made a motor-drive output pulse and is supplied to the D.C. motor 40. Consequently, the slackening part of the ink- ribbon driven by a stepping motor 32 is wound immediately after the control signal SMP.

Abstract: PURPOSE:To acquire a sensor not requiring readjustment and others even in the case of decrease of emission amount due to use for a long time by providing an output decrease compensation circuit to vary standard voltage in accordance with decrease of an output characteristic of a light receiving element when the output characteristic of the light receiving element decreases. CONSTITUTION:Power voltage Vcc is respectively supplied to a light emitting diode D through a resistor R4 and to a collector terminal of a phototransistor Tr through series circuits of two resistors RL1, RL2. Collector terminal voltage of the phototransistor Tr is introduced to a reversal input terminal of a comparator A1 as output voltage. Standard voltage obtained by dividing pressure of power voltage by series circuits of two resistors R5, R6 is introduced to a normal input terminal of the comparator A1. Consequently, when emission amount of the light emitting diode D decreases due to use for a long time or an output characteristic decreases because of decrease of a light receiving characteristic of the phototransistor Tr, this standard voltage is varied by an output decrease compensation circuit 1.

Abstract: PURPOSE:To enable a head to be accurately stopped at a predetermined position, by once stopping a DC motor being rotated when the first detection point of an operating element is detected by a sensor, thereafter driving the motor by pulses, and thereafter stopping the motor when a second detection point is detected. CONSTITUTION:When a DC motor 7 is rotated in the direction of an arrow (a) and the first detection point alpha of an operating part 10a of a turnable lever 10 comes into a recessed part of a sensor 8, a sensor circuit block 20 generates a position detection signal, and a driving current for the motor 7 is cut off based on the signal, thereby rapidly stopping the motor 7. Thereafter, pulses generated by a motor-controlling block 22 are supplied to the motor 7 through a motor-driving block 23 to rotate the motor 7 at a low speed. When the second detection point gamma of the operating part 10b is passed through the recessed part of the sensor 8, the sensor circuit block 20 generates a position detection signal, whereby the generation of the pulses is topped, and a reverse current driving signal for braking is supplied from a braking timing block 24 to the motor 7.

Abstract: PURPOSE:To enable a thermal head to be securely protected from being burned due to an overcurrent, by a method wherein it is detected whether or not printing data are present in a normal period of time, it is detected whether or not a thermal head is located at a normal printing position making contact with a platen, and supply of a driving power source is controlled by the logical sum of the detection outputs. CONSTITUTION:The first position sensor part 10 detects whether or not the thermal head 5 is located at the printing position, and outputs a detection signal to a signal input terminal 30A of a thermal head protective circuit 30. The printing data are supplied to a printing data input terminal of a thermal head driving part 25 through a signal input terminal 20, and are supplied to a signal input terminal 30B of the protective circuit 30. The protective circuit 30 detects whether the printing data to be supplied to the driving part 25 are present in a normal period of time, detects whether or not the head 5 is located at the normal printing position making contact with the platen 1, and a relay coil switch 40B is opened and closed by the logical sum of the detection outputs, thereby controlling the supply of the driving power source to the driving part 25.
