A cordless telephone apparatus includes: a battery which is rechargeable with a direct current based on an electric energy supplied from an outside of the cordless telephone apparatus; a constant current circuit which limits the direct current charged into the battery to a constant current; a voltage-dividing resistor which divides a direct voltage inputted into the constant current circuit; an A/D converter which converts a value of the direct voltage divided by the voltage-dividing resistor into digital data; a charging-state acquiring portion which acquires a charging state of the battery based on the digital data from the A/D converter; and a charging-state informing portion which informs the charging state of the battery acquired by the charging-state acquiring portion.

A telephone including: a telephone main unit incorporating a battery and having: a standby state determination unit that determines whether or not the telephone main unit is in a standby state; a battery voltage detection unit that detects voltage across input and output sides of the battery; a voltage determination unit that determines, when the standby state determination unit determines that the telephone main unit is in the standby state, whether or not the detection voltage detected by the battery voltage detection unit exceeds a threshold voltage set based on a voltage when the battery is normally connected; and a warning unit that issues a warning to the effect that power cannot be supplied from the battery when the voltage determination unit determines that the detection voltage exceeds the threshold voltage; and a charger that supplies power to the battery.

Telephone

An electric circuit board has a plurality of conductive pads on a base plate for connection with conductive pins of an electric device such as a thermal head of a facsimile machine. Protective parts are formed on the base plate at the right side of the rightmost conductive pad and at the left side of the leftmost conductive pad. The conductive pads and the conductive pins are soldered by solders heated and melted by a light beam. The protective parts protect the base plate from being burnt by the light beam even when the light beam is projected transversely across the pads from the right side of the rightmost pad to the left side of the leftmost pad.

Electric circuit board having protective part against light beam

An image forming apparatus for irradiating an image light on a photosensitive recording medium having at least one photosensitive wavelength range on the basis of an image information to thereby form an image on the photosensitive recording medium, comprising a semiconductor laser for emitting an image light or a thermal cathode for emitting thermoelectrons having the image information, a photomultiplier or microchannel plate for converting the image light or the thermoelectrons into secondary electrons while the image forming information is kept, and multiplying the secondary electrons, and a fluorescent screen for converting the multiplied secondary electrons into an intensified image light. The intensified image light may be supplied on a photosensitive recording medium while the image forming information is kept, thereby forming an image on the photosensitive recording medium.

Color image forming apparatus having image intensifier unit

An image recording apparatus is disclosed which comprises a CRT on which an image produced by an external host computer is displayed. An image recording device records a copy image corresponding to the image displayed on said CRT on a photosensitive recording medium. A control unit controls a CRT driving device corresponding to an aspect ratio data so that the aspect ratio of the CRT is adjusted to that of an external CRT attached to the host computer.

Image recording apparatus using a CRT as a light source

In an image recording apparatus for recording an image of an original document on a photosensitive recording sheet, a light source such as a halogen lamp is provided which emits a light and applying it to the image face of the original document while moving the latter. The photosensitive recording sheet is exposed to the resultant image bearing light, in which the photosensitive recording sheet is moved at a speed equal to the moving speed of the original document. A light intensity sensor detects the intensity of the light applied to the original document, and when the intensity of the light applied thereto is lowered than a required level, the moving speeds of both the photosensitive recording sheet and the original document are lowered to thereby maintain an exposure rate at substantially constant.

Image recording apparatus having exposure control unit

Input data on a colored or monochromatic image having a gradation are recorded on a light transmissive sheet to prepare mask originals. The data on the colored image are separated into data corresponding to red, green and blue color components and the data on each of the color components are converted to dither data. At least two mask originals are prepared for each color on the basis of the dither data associated with the color. Photosensitive pressure-sensitive recording paper coated with microcapsules each encapsulating a chromogenic material is exposed to light through the mask originals and is then subjected to development under pressure, whereby the image is reproduced thereon. The mask originals carry at least two different patterns of image data for each color.

Half-tone image reproducing method of improving gradation without loss

A copying apparatus operable with an original having an image-bearing surface on which images to be reproduced are supported. A radiation reflected by the image bearing surface is focused on a photosensitive paper, by a self-focusing lens array, so that latent images corresponding to the images on the image-bearing surface are formed on the photosensitive paper. The latent images are developed into visible images by a developing device such as a device adapted to apply a pressure to the photosensitive paper. The photosensitive paper may be a self-activated type having a photosensitive material and a developer material which chemically react with each other in the developing process. Alternatively, a separate developer paper having a developer material is superposed on a photosensitive paper having only a photosensitive material. In this case, the photosensitive and developer papers are superposed on each other for development of the latent images due to the chemical reaction between the photosensitive and developer materials. After the development, the two papers are separated from each other by a separating device such as a roller separator.
