Title: Printer with automatic paper-supplying device
Inventor: WADA KENICHI
IPC: B65H11/00
Filed: 1986-03-10
Abstract: PURPOSE:To prevent a paper jamming from occurring at the time of manual-insertion paper supply or at the time of discharging a paper, by providing a paper guide member provided with a switching means at an intermediate part of a passage from a platen part to a discharged paper containing part so that the entrance of a discharged paper into the containing part is inhibited when the paper guide member is located in one of selective positions. CONSTITUTION:A paper separator 41 is in the shape of inverted V, and an apex part thereof is located in the vicinity of a paper-discharging port 28. At the time of automatic paper supply, the paper separator 41 is brought closer to a lower end part of a guide 26, so that a paper is fed into the paper-discharging port 28 without any hindrance. At the time of manual-insertion paper supply, the apex of the separator 41 is moved, and supplying of a paper by manual insertion can be performed through a gap between a plate part 41a and the guide 26. Since the paper is inhibited from entering into the port 28, the paper is discharged along an upper surface of a guide plate 27. Accordingly, even when the length of the paper is small or the width of the paper is larger than that of an automatic paper-supplying device, the paper is securely guided to the exterior without jamming, since the width of the paper separator is larger than that of feedable papers.

Title: Image recorder
Inventor: TSUKADA YUKIHIKO
IPC: G03B27/58
Filed: 1988-03-09
Abstract: PURPOSE:To prevent a photosensitive material from crawling under an exposure board and sagging over the exposure board by obtaining such a structure that the photosensitive material is carried toward the upper part of the exposure board. CONSTITUTION:An exposure part is provided, which performs exposure on the exposure board 60 with incident light from an optical system while the photosensitive material A such as heat developing photosensitive material, etc., is carried from a pair of rollers 56c to a pair of rollers 56d. The rollers 56c are set so that they have a desirable tilt angle to the optical axis 32 of the incident light. Since the photosensitive material A is carried in a direction shown by a dotted line at the time of starting to record an image, jamming caused by the photosensitive material A's crawling between the roller 56c and the board 60 can be prevented. Since the upper roller of the rollers 56d is formed so that its diameter is large, the leading edge part of the photosensitive material A is surely held and the sagging of the photosensitive material A can be reduced because the winding speed of said roller becomes larger.

CONSTITUTION:The voltage monitoring IC 1 is connected to the output of the voltage monitoring IC 2 with the low operation power supply voltage, the node between both the ICs 1, 2 is connected to the reset terminal of the microprocessor 3, a reset line L6 inputted to the chip select (CS) terminals of respective memories 5, a decoding circuit 4 for decoding an address bus L9, and the output lines L8 of the circuit 4 are connected to the other CS terminals of respective memories 5, and the micropocessor 3 and the memories 5 are connected to a data bus L7. When the operation of the IC 1 exceeds the operable voltage point (a) of the processor at the rise of the power supply, a reset signal is outputted. The reset signal is outputted before the IC 2 arrives at the point (a). Thereby, an OR logic between the outputs of the ICs 1, 2 is outputted to the line L6. Since the IC 1 is reset before the operation of the microprocessor 3, the microprocessor 3 can be prevented from generating runaway.
