A light source device includes a xenon lamp, a rotary shutter, a main CPU for controlling drive of these components, and a sub CPU. The main CPU operates when receiving a reset cancel signal from a reset circuit. Between the sub CPU and the reset circuit, an AND circuit is provided. When the reset cancel signal from the reset circuit and a lighting completion signal indicating completion of lighting the xenon lamp are both input, the AND circuit outputs the reset cancel signal to the sub CPU. After the output of the lighting completion signal, the sub CPU operates to drive the rotary shutter. When high-frequency noise which occurs at the time of discharging the xenon lamp stops, the rotary shutter is activated and thereby generating pulses of illumination light.

An electrical connecting apparatus 10 comprises: a base plate 16 provided on its underside 14 with a plurality of pedestals 12 at intervals in a front-back direction; and multiple contact groups, each of which has a first contact 18 and a second contact 19. Each first contact 18 includes a needle body portion 24 having a rear end portion 20 supported on the pedestal 12 and a front end portion 22 which is a free end and extending leftward. Each second contact 19 includes a needle body portion 25 having a rear end portion 21 supported on the pedestal 12 and a front end portion 23 which is a free end and extending rightward. When the first contact 18 is broken, the second contacts 19 can be used.

The present invention provides an electrical connecting apparatus in which no strong stress acts on a coupling portion of an arm portion continuing into a base portion by a moment force acting on the arm portion. A probe sheet comprising a probe sheet main body and a plurality of probes formed to be protruded from one surface of the probe sheet main body is provided. For formation of the arm portion of the probe, a metal material for an arm main body portion continuing into a probe tip portion is deposited on a base table with an approximately uniform height dimension. Also, a metal material for a reinforcing portion constituting an arm portion together with the arm main body portion is deposited at an area on the arm main body portion distanced from the probe tip portion with an approximately uniform height dimension. Further, a metal material for forming a base portion that is connected to at least the reinforcing portion is deposited without covering a step consisting of one end of the reinforcing portion located on the probe tip portion side and the arm main body portion. Thus, the arm portion in which a height dimension at a coupling portion with the base portion is larger than that at another part except the coupling portion is formed.

There is provided a printing method that can provide an image formed object which can suppress a change in density of a visible dye image and a lowering in fluorescence intensity and, at the same time, is free from concave/convex of the image surface and has a latent image invisible even under visible light. The printing method comprises a first step of forming a latent image of a fluorescent dye by thermal diffusion transfer; and a second step of providing a visible dye on the latent image by thermal diffusion transfer.

The present invention relates to a method for fluorescent image formation which can form a highly scratch-resistant fluorescent full-color image using a colorless fluorescent agent and can freely regulate the tone of color mixture of a combination of two or more fluorescent colors in order to impart, to articles, a higher level of forgery preventive function than a prior art technique and a print having a high level of forgery preventive function. The invention characterized in that fluorescent inks are provided that are substantially colorless upon visible light irradiation and contain organic fluorescent agents which, upon ultraviolet light irradiation, emit fluorescences in a visible region, and that two or more fluorescent inks, which emit fluorescences having mutually different color tones, are deposited on a printing face in its image formation region according to information on an image to be printed in a dot matrix manner so that dots of one color do not overlap with dots of another color.

The rotating speed of a photosensitive body is reduced for preventing deterioration thereof due to ozone in an electrophotographic device which comprises the photosensitive body, a charger which uniformly charges the surface of the photosensitive body, and a motor control unit which performs drive control for a motor which drives the photosensitive body. The motor control unit provides a plurality of speed levels including a first speed level for rotating the photosensitive body during printing and another speed level for rotating the photosensitive body at a reduced speed lower than the speed used during printing. The speed is changed-over between the plurality of speed levels depending on the operating condition. Thereby, deterioration of the photosensitive body due to ozone generated from the charger is prevented, and additional deterioration of the photosensitive body due to rotation thereof other than during a printing operation is also prevented.
