Title: Indicator for meter
Inventor: ARAKI TERUAKI
IPC: G12B11/04
Filed: 1995-02-09
Abstract: PURPOSE: To secure the appearance of a meter even in the case where an indicator is irradiated with the light from the top of the indicator when the indicator is not lighted by forming the longitudinal cross section of the lower surface of an indicator main body into the saw tooth shape. CONSTITUTION: When a light emitting body 2 is lighted and an indicator main body 1 is irradiated with the light, the light emission, which enters from the light emitting body 2 through a light receiver surface 1b, is efficiently reflected to the top surface of the indicator main body 1 by the reflecting surface, and the lighting luminance of the main body 1 is improved. When the light emitting body 2 is not lighted, even in the case where the main body 1 is irradiated with the external light, reflection of the external light at the angle, at which the reflected light passes through the top surface of the main body 1, is prevented by the saw tooth irregular part 1a formed in the lower surface of the main body 1. Consequently, generation of the phenomenon that the main body 1 seems to be shining when the main body 1 is not lighted and that the main body 1 seems to be lighted is eliminated.

Title: Thermal printer
Inventor: SANO HIDEKI
IPC: H04N1/23
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To surely and sufficiently restrict 'bleeding' by taking influences of a previous history whether or not electricity for printing is supplied to heating elements, and the like into account. SOLUTION: In letting a coloring layer color which colors with a low heat energy amount, printing out is carried out while a heat-sensitive paper 22 is transferred at a transfer speed Va. In letting a coloring layer color which colors with a high heat energy amount, if an ambient temperature of a thermal line head 9 is high, printing out is carried out while the heat-sensitive paper 22 is transferred at the transfer speed Va. If the ambient temperature is low, a history of printing/power supply of previous X dots is judged for each heating element of the thermal line head 9. If there is no heating element of a dot whose immediately preceding X dots are not printed out at all, printing is carried out while the heat-sensitive paper 22 is transferred at the transfer speed Va.  On the other hand, if there is even a single heating element, printing is carried out while the heat-sensitive paper 22 is transferred at a speed Vb lower than the transfer speed Va.

Filed: 1988-02-02
Abstract: PURPOSE:To prevent erroneous use of an electrophotographic printer in a state where the toner is not proper by providing a toner detecting section in the development device constituting the printer and causing the section to inform that no toner is detected and the toner quantity becomes less than a prescribed quantity. CONSTITUTION:The height of the toner contained in a development device 22 provided in a laser printer is detected with a toner sensor 24 and the output voltage of the sensor 24 is supplied to an informing unit 26. The unit 26 makes the output voltage smoother by means of a smoothing circuit 30 provided in the unit 26 and the voltage thus obtained is inputted to comparators 32 and 34. When the output voltage of the circuit 30 is lower than a 1st reference voltage, it is judged by the comparator 32 that the sensor 24 and informing unit 26 are disconnected with each other. When the output voltage of the circuit 30 is higher than 2nd reference voltage, on the other hand, the comparator 34 judges that the toner is insufficient. In any case, an LED 58 is turned on and printing operations of this printer are inhibited. Therefore, not only the insufficient quantity of toner, but also faulty connection, disconnection of a connecting line, un-mounting of development device, etc., can be detected.

IPC: G01R31/26
Filed: 1988-02-02
Abstract: PURPOSE:To manage with one DC inspection process and to reduce operation man-hours by providing a capacitor, a resistance, a diode, etc. CONSTITUTION:When an input signal 3 is inputted to a circuit 2 to be inspected, the output 4 of the circuit rises a delay time later. Consequently, the output 15 of a C-MOS logic circuit 15 becomes a high-level output for the delay time. When the output 15 goes up to a high level, a capacitor 14 is charged with the time constant determined by the capacity value of the capacitor 14 and the resistance value of a resistance 13. Then when the output 4 rises, the output 15 falls. In this case, a diode 12 is biased reversely, so there is no place for the charges in the capacitor 15 to discharge and its charging level is held; and the charging level of the capacitor 14 is measured by a DC tester eventually to measure the delay time.
