Title: Recording paper form conveyer for picture recorder
Inventor: OKUI SUSUMU
IPC: G03G15/00
Filed: 1990-02-02
Abstract: PURPOSE:To improve an operational quality so as to surely convey various paper forms by enabling a movable guide plate to open a conveying path, in a condition that a conveying unit is drawn out, and disabling the movable guide plate from opening the conveying path when the conveying unit is pressed in and placed in a conveyable condition. CONSTITUTION:Since a fixed rail member 162 is not provided below an open/ close guide plate 146 in a condition that a unit casing 101 is drawn out from a copying machine main unit, the open/close guide plate 146 can be swivel- opened to process a paper jam in a conveying path by opening the plate 146. After completion of processing the jam, the unit casing 101 is pressed in the copying machine main unit, and in a condition that the unit 101 is pressed in and stopped, a protruding part 146C of the open/close guide plate 146 touches an upper plane part 162G of a fixed rail member 162 to restrict swiveling the guide plate 146 with its opening made impossible. Accordingly in this condition, the open/close guide plate 146 is position-restricted and prevented from swiveling by external force, and a paper form can be fed by holding the paper form conveying path in a predetermined space.

Abstract: PURPOSE: To prevent develop of frosting in an exterior heat exchanger by amplifying the static pressure between the heat exchanger and a blower, controlling the refrigerant in heating for proportional control of the opening of an expansion valve, and controlling the low pressure.  
     CONSTITUTION: With a four-way valve 2 is changed over for heating cycle, a refrigerant flows from a compressor 1 through the valve 2, room heat exchanger 6, check valve 8, expansion valve 7, exterior heat exchanger 3, and the valve 2 and returns to the compressor 1 as shown by the broken line arrow. When frosting occurs in the heat exchanger 3 under the influence of exterior temperature, exterior humidity, and room temperature, the static pressure between the heat exchanger 3 and an exterior blower 11 changes. The change is amplified by a pressure amplifier 14 and transmitted to the expansion valve 7 to move a diaphragm 15 in a diaphram  chamber 16. This incraeses the opening of a valve and increases the vaporization  pressure in the heat exchanger 3.

Filed: 1989-02-06
Abstract: PURPOSE:To prevent a guide rail from being deformed and the wear and to execute positioning with high accuracy by connecting the guide rail and a rail housing by using plural fitting members whose connecting force is different. CONSTITUTION:A guide rail 5 is attached to a rail housing 6 with two pieces of fitting screws 11 (11a, 11b). Also, the joint forces Fa, Fb are managed to a prescribed value by making the torque at the time of clamping different from each other.

Accordingly, the relative position of a servo-head 3a and a data head 3b is not varied, an off-track quantity becomes about zero, and also, wear scarcely occurs, and positioning can be executed with high accuracy.

Abstract: PURPOSE:To give flexibility to pen handling, to eliminate troubles at the time of modifying the color of a pane and to obtain an identical display color without fail by installing a detection circuit and a color sensor whose output signal varies in accordance with a received wavelength on a pen storing part. CONSTITUTION:The pen storing part 12 is provided with the color sensor 10 outputting different signals with respect to four types of wavelengths that the sensor 10 receives, and the detection circuit 11 which receives the output signals of the sensor 10 and identifies the presence or absence of picture drawing pens 1-4 and the wavelengths of the output signals. By light projected by a light source 9 reflecting plates 5-8 reflect specific wavelength, and the sensor 10 receives the wavelength and outputs the signal corresponding to said length. Receiving the output signal of the sensor 10, the circuit 11 identifies the presence or absence of the pens 1-4 and the reflected wavelength, however it does not detect the reflected wavelength of the pen in the middle of drawing a picture. Thus the color of the pen in use can be identified, and the pens can be stored at any places. By giving flexibility to the pen handling, troubles at the time of modifying the color of pen are eliminated, and the display color can be made identical without fail.
