摘要:
An image processing apparatus for eliminating the necessity of providing a first control board with a power supply unit beforehand for backing up data stored in an image memory, and reducing the cost of the apparatus as a whole. To accomplish this, in an image processing apparatus including a system control board configured to perform image processing, a memory backup function is enabled for an image memory storing data to be processed by the system control board, when a facsimile communication board is connected.

A communication apparatus having an automatic dialing function such as redial, one-touch dial, abbreviated dial comprises: a memory to store the dial number; a detector to detect a predetermined hooking operation by another terminal; and a transmitter to transmit a dial signal according to the dial number stored in the memory on the basis of the detection of the predetermined hooking operation by the detector. The detector has a second detector to detect an off hook of another terminal. The transmitter sets a predetermined flag on the basis of the detection of the predetermined hooking operation and, when the off hook is detected, if the predetermined flag has been set, the dial signal according to the dial number stored in the memory is transmitted.

In an image information read apparatus, shading distortion data of a light source are stored in a plurality of memory means, and the shading distortion data is read out of one of the memory means depending on a position of an original document. Content, of one of the plurality of memory means is retained even after the turn-off of a power supply. By this arrangement, a proper shading distortion correction is always attained at any position of the inserted original document even when the original document is partially scanned from an intermediate point, a proper initial value for shading distortion correction can be inputted so that a proper shading correction is attained to improve a quality of image.

A wireless telephone system includes plural phones, each having a radio transmitting/receiving unit and a storage unit for recording and reproducing incoming messages, and a base unit connected to a telephone line that communicates by radio with the plural phones. In one arrangement, the base unit selects a desired phone and the selected phone records the incoming message. In another arrangement, the plural phones do not include storage units and base unit is adapted to select a desired phone according to a DTMF signal and to record an incoming message corresponding to the selected phone in a storage unit. The base unit reads out the stored incoming message in response to a designation from the selected phone, transmits the message to the phone and the incoming message is reproduced by the selected phone.

Disclosed is a facsimile apparatus equipped with an automatic answering telephone function, as well as a communication method in this apparatus. When a tone signal from a line is detected after the start of storage of a voice message in response to an incoming call, the voice message presently being recorded is not counted as a received message and a voice message received next is stored in the area in which storage has just been performed. Further, when a DTMF signal, which is a control signal of the automatic answering telephone, is detected, a transition is made to facsimile communication in response to a CNG signal. Thus, erroneous operation in facsimile communication due to a CNG signal recorded in the automatic answering telephone is prevented.

A facsimile apparatus can output a plurality of kinds of audible sounds. In the apparatus, the level of a sound is increased when outputting a specific audible sound compared with when outputting audible sounds other than the specific audible sound.
摘要:
An electronic apparatus comprises an electronic circuit unit having heat-generating electronic parts and cooling jackets fed with a coolant so as to cool the heat-generating electronic parts, and a coolant cooling unit having a heat exchanger for cooling the coolant from the cooling jackets and a pump for pressurizing and feeding the cooled coolant to the cooling jackets. The electronic circuit unit and the coolant cooling unit are housed in the same cabinet, and a partition plate is provided between the electronic circuit unit and coolant cooling unit to partition the two so that in the event of occurrence of liquid leakage, the coolant may be prevented from migrating from the coolant cooling unit to the electronic circuit unit. A coolant drainage drain may be provided at the bottom of a U-shaped portion of a path for circulating the coolant to facilitate drainage of the coolant.
摘要:
A roof opening and closing apparatus for a vehicle including a lid and a pivotal mechanism for opening and closing the lid. The opening and closing mechanism includes three shoes slidable along the vehicle body. One shoe is connected to and supports the forward end of the vehicle lid. The second slidable shoe supports one end of a link. The link is fixed at its middle portion to the third sliding shoe and at its other end to the roof lid. The link pivots as the third sliding shoe is moved forward or backward.
