摘要： PURPOSE:To prevent double feed in paper sheet separation by suspending the turning operation when a paper sheet is sucked by a sucker and turned by a slight angle and by eliminating the double set due to static electricity and turning the sucker. CONSTITUTION:A sucker 31 is turned reversely and attached on the upper surface of the piled-up paper sheets 16 and the sheet 16 is vacuum-attracted. Then, the sucker 31 is turned around the center of revolution, and the paper sheet is nipping-transported by a pair of paper feeding rollers 19a and 19b. In this case, the turn around the center of revolution of the sucker 31 is once suspended after the turn in a slight angle. Accordingly, even if plural paper sheets 16 are lifted up by static electricity, etc., the second paper sheet and the succeedings are dropped during the stop because of the toughness of the paper sheet, and only the uppermost paper sheet is attracted. Then, the sucker is turned again, and only the uppermost paper sheet is nipping-transported by a pair of feeding rollers 19a and 19b, and double feed is prevented.

摘要： PURPOSE:To suppress unnecessary heating at low humidity and to reduce the power consumption by providing a means which operates a heating means or increases heating energy only at high humidity to a recording device which decreases in recording characteristics when relative humidity is low. CONSTITUTION:A microcapsule sheet 1a fed from a cassette 1 is put on a transparent original 3 inserted into an original insertion slit 32 one over another on a transparent belt 4, and scanned and exposed by an exposure lamp 7. Developing paper 8a carried from a cassette 8, on the other hand, is passed between rollers of a pressure developing unit 2 together with the sheet 1a to form a sharp image on the paper 8a by the coloring of a developer by the breaking of microcapsules at an unexposed part. When the humidity high, the developer is offset on the sheet 1a, so the cassettes 1 and 8 need to be heated and dried, which is detected by the regenerated cellulose belt 15 of a humidity detecting means; and heaters 12 and 13 are powered on only when necessary to reduce the power consumption.

摘要： PURPOSE:To accomplish concurrent operations in exposing and developing steps, to shorten the image forming time and to scale down a device by making a speed obtained by multiplying a 1st speed by enlargement/reduction multiples almost equal to a 2nd speed. CONSTITUTION:To move an original and a light source 3 relatively at the 1st speed V1, images such as latent images are formed on a photosensitive recording medium 37 at the speed V1n identical to the speed obtained by multiplying the 1st speed V1 by an enlargement/reduction multiple (n). At the time of development, a developing means 20 developing the photosensitive recording medium 37 and the medium 37 are moved relatively at the 2nd speed V2, and the photosensitive recording medium 37 is developed at a speed identical to the 2nd speed V2. In such a way, operation is controlled so that the speed obtained by multiplying the 1st speed V1 by the enlargement/reduction multiple (n) can be almost equal to the 2nd speed V2. Thus, operations in the exposing and developing steps can be performed concurrently. In addition an exposing part and a developing part can be arranged closely in the title device, whereby it can be scaled down.

摘要： PURPOSE:To output an image having gradation to a recording medium, by mounting a pin wherein the diameter thereof is different along the axial direction thereof and becomes large in plural stages as the pin separates from the recording medium and a means for changing the diameter of the pin contacting with the medium. CONSTITUTION:When the energizing force of a support 9 in the axial direction thereof is larger than that of the first spring 10 and smaller than the energizing forces of the first and second springs 10, 13, a printing part 8 is perfectly received in the first housing part 11 and, when the first housing part 11 is not received in the second housing part 12, the printing part 8 and the first housing part 11 print paper 5 through a ribbon 2. In this case, the printing of a dot having the size corresponding to the diameter of the first housing part 11 is performed to the paper 5. Further, the diameter of the first housing part 11 is smaller than that of the second housing part 12 and larger than that of the printing part 8. Therefore, by changing the energizing force applied to the support part 9, a wire pin 7 is changed in the area of the printing part thereof struck to the recording paper 5 and, when a large area is desired to be printed, said energizing force is increased and, when a small area is desired to be printed, the energizing force is reduced.

摘要： PURPOSE:To output beautiful images even with an ancillary function by using a 2nd window as a main exposing window of the ancillary function, such as slide copying, and using a 1st window as an auxiliary exposing window when the image having a gradation characteristic is required as output. CONSTITUTION:A sub-exposing plate 103 is inserted to the prescribed extent by a motor 101 and a gear 102. A shutter 113 is simultaneously moved to the prescribed extent so as to be closed up to the prescribed extent so as to be closed up to the position of the 1st exposing window 113 where only the reflected light by an exposing lamp 18 of the sub-exposing plate 103 is made incident. The 1st window is irradiated only with the auxiliary exposing light in this way. The reflected light of the sub-exposing plate is made incident on the 1st window by the exposing lamp 18 and a photosensitive pressure sensitive sheet 50 is subjected to auxiliary exposing. The photosensitive pressure sensitive sheet 50 in the 2nd window 116 is irradiated with the light transmitted through a slide 92 by an exposing lamp 94 of a slide option. The latent image corresponding to the slide 92 is thereafter recorded on the photosensitive pressure sensitive sheet 50. The beautiful imags having the gradation characteristics are outputted in this way even if the copying of the ancillary function is to be executed.

摘要： PURPOSE:To form an in-focus image by exposure by maintaining the squareness between a mirror holding plate where the 1st plate surface part of the support member is fixed and the exposure base even if a bending angle varies. CONSTITUTION:The exposure base support plate 1 consists of the 1st plate surface part 1a composed of an inverted L type horizontal part, a 2nd plate surface part 1b which is bent almost at right angle from the inverted L type vertical part to this side, and a 3rd plate surface part 1c which is bent in parallel to the 1st plate surface part 1a in front of the 2nd plate surface part 1b. Further, the 3rd plate surface part 1c is formed in a nearly L shape and its reverse end surface 1d is positioned accurately at specific distances to a group of holes 2a - 2c of the 1st plate surface part. Therefore, even if a spring-back phenomenon is caused at the time of bending, the relative position of the 3rd plate surface part end surface to a reference hole becomes nearly equal only by the perpendicular deviation of the 2nd plate surface part 1b from the 1st plate surface part 1a and the perpendicular deviation of the 3rd plate surface part from the 2nd plate surface part 1b. Consequently, the holding plate of a mirror and the exposure base 24 are held at a specific distance and inclination due to right-left unbalance is eliminated.

摘要： PURPOSE:To facilitate assembly and to accurately set a distance between the reflecting point of a final mirror and an exposing board by providing an elastic member which allows the exposing board to abut on a holding member and positions it with respect to the final mirror. CONSTITUTION:The elastic member 9 is provided, which allows the exposing board 6 to abut on the holding member 4 and positions it with respect to the final mirror 5. Namely, both ends of the board 6 are pressed upward by a leaf spring 9 in an opening 20 before an optical unit 2 is placed on a main body unit 3. When the optical unit 2 is accurately placed on the unit 3, the lower surfaces of projections 4a and 4a formed at the lower end of a leg 4 abut on the board 6 to press downward by contracting the sping 9 a little. By allowing the lower end of the leg 4 to abut on the board 6 in a state where the board 6 is pressed upward by the spring 9, a distance A between the reflecting point of the final mirror 5 and the board 6 is always constant. Thus, the distance between the final mirror 5 and the exposing board 6 is made constant and the assembly is facilitated.
