To provide a D/A converter including a sampling circuit capable of suppressing a high-frequency component in an input signal without obstructing downsizing of electronic equipment. A D/A converter includes a first capacitative element unit including plural sampling capacitors, a second capacitative element unit including plural sampling capacitors, a first switch unit including the plural switches configured to store charges in the plural sampling capacitors of the first capacitative element unit and to transfer the charge, and a second switch unit including the plural switches configured to store charges in the plural sampling capacitors of the second capacitative element unit and to transfer the charge. The first and the second switch units operate alternately.

D/A converter

An A/D converter comprising: a sampling circuit including a continuous section, a sampling and holding section for intermittently sampling an input signal based on an analog signal input from the continuous section to hold and transfer the sampled signal, and a digital section for outputting a signal transferred from the sampling and holding section as a digital signal; and a control circuit for supplying a clock signal in which jitter is not added to the continuous section and supplying a clock signal in which the jitter is added to the sampling and holding section.

A sampling circuit includes a continuous section which is a circuit for transmitting a continuous signal; a digital section for transmitting a signal which is sampled and quantized; and a sampling and holding section for transmitting a signal which is sampled but not quantized between the continuous section and the digital section. The sampling and holding section includes capacitors for accumulating charge generated by an input signal and plural switches for accumulating the charge in the capacitors. The plural switches receive plural clock signals having different operation timings and perform an ON/OFF operation in response to the supplied clock signals.

Provided is a key sheet allowing reliable sliding operation input through accurate coordinate position detection and depressing operation input of satisfactory depression operability through clear click feel. Fixation layers are formed at positions under depressing operation portions, and there are no fixation layers in portions around the depressing operation portions but gaps are formed. With this construction, it is possible to suppress a depression operation load to a low level at a time of depressing input operation, and, when contact switches with click feel are depressed, the click feel can be easily transmitted. Further, a surface sheet has movable contact portions which enter the gaps at a time of sliding input operation and which are displaced so as to be capable of coming into contact with a sensor sheet. With this construction, it is possible to sense, in a stable manner, capacitance at an in-plane position of a sliding operation surface of the sensor sheet.

Key sheet

Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A key sheet has a base sheet formed of a rubber-like elastic material in which a heat conductive filler is mixed. Thus, if a semiconductor device on a board generates heat, it is possible to suppress local heat storage by the heat conductive filler of the base sheet. Further, there is no need to provide a separate member for heat diffusion between the board and the key sheet, making it possible to realize a reduction in thickness. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses, and the requirement for a reduction in the thickness and weight of electronic apparatuses.

Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A base sheet of a key sheet is provided with a heat diffusion sheet. The heat diffusion sheet is provided with a graphite sheet and a resin film and, in some cases, a thin metal plate. The base sheet itself thus constitutes the heat diffusion sheet, so even if no member for heat diffusion is provided between a board and the key sheet, it is possible to diffuse local heat generated by a semiconductor device in the face direction of the base sheet. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses and to meet the requirement for a reduction in the thickness and further in weight of electronic apparatuses.

Rear projection television receiver

A camera-equipped recording/reproducing apparatus is equipped with a lens assembly having a lens group and a body having a first side face and a second side face opposite to the first side face when viewed from an object to be photographed. The body is provided in series with and behind the lens assembly in a direction of an optical axis of the lens group when viewed from the object. A monitor screen is provided on the first side face of the body. A grip is provided on the second side face of the body. The grip houses a recording/reproducing unit. The grip is rotatable about an axis almost orthogonal to the optical axis.

Camera-equipped recording/reproducing apparatus

As a key sheet for fixing a base sheet and key tops to be arranged on the base sheet using adhesive layers, a key sheet where the key tops and the base sheet are fixed, is obtained by forming printed adhesive layers of the key tops on facing surfaces of at least either of the key tops or the base sheet by means of printing, and then bringing the printed adhesive layer into contact with the other facing surfaces in a softened or molten state, and by curing the printed adhesive layer.
