A printer emulating apparatus obtains a command signal which is outputted from a controller unit via an interface, and emulates a state of an engine unit in accordance with a notification of an elapsed time by a timer for notifying the elapse of a predetermined time and the obtained command signal. A response signal is transmitted via the interface in accordance with the emulated state of the engine unit and the obtained command signal. An image sync signal is generated to the controller unit in accordance with the emulated state of the engine unit.

Printing apparatus and method for verifying a printer controller

In case of developing an image output apparatus including a controller to generate image data and an engine to form an image on a medium based on the image data, in order to verify the image data from the controller in real time, halftone image data before conversion into a PWM signal is converted into a serial signal and output instead of the PWM signal for output to the engine unit if a controller operation verification apparatus is used instead of the engine unit. Thus, multivalued halftone data not including an error due to a conversion process can be sent to the controller operation verification apparatus without adding signal line and driver circuit dedicated for sending the multivalued halftone data, whereby it is possible to improve development efficiency of the image output apparatus by accurate verification of the output image data.

In a multibeam-type image printing apparatus, a process of adjusting a beam scanning position at which a photosensitive body is scanned is simplified. More specifically, consumption of a developing agent such as toner or the like is suppressed, and the time required for the adjustment process is shortened. A test pattern is formed on the photosensitive body using the first beam out of a plurality of beams, thereby detecting the irradiation position of the first beam with respect to the photosensitive body. Correction data for all the beams are generated on the basis of adjustment data as the detection result and predetermined beam information (information indicating a relative positional relationship between the plurality of beams on the photosensitive body). Image transfer clocks and scanning start positions are set on the basis of the correction data.

Image printing apparatus and image printing method

In order to print an image sensed by a digital camera using a printing apparatus for forming an image on a print medium, image data corresponding to the sensed image is converted into print data, and the converted data is transmitted to the printing apparatus, thereby providing an image processing system which can print an image sensed by the digital camera using the printing apparatus without the intervention of any computer, and a digital camera and printing apparatus suitable for the image processing system.

A toy basketball game having a court floor, a stand attached to the floor for a backboard ring and net, an articulated player and a movable base for the player. The player contains a compressible spring in one leg which is held compressed by a lever on the player's leg, which lever releases the spring to cause the player to jump and to raise its arm having in its hand a releasable ball, which ball releases when the player's arm contacts the ring of the basketball basket. The base has a rotatable wedge-shaped plate for changing the angle of jump of the player so as to cause the player to be projected toward the ring from any location of its stand on the court. If desired, the ring and the arm of the player may be provided with adhering roughened surfaces so that the player can hang on the ring.

In a telephone exchange apparatus or a facsimile data broadcasting apparatus incorporating facsimile communication facility for broadcasting image data to a plurality of facsimile apparatuses, image data is concurrently broadcasted by sharing a single facsimile modem. In this case, the apparatus has (1) an arrangement wherein transmission of image data is assigned to the facsimile modem, and transmission/reception of control signals is assigned to a plurality of V.21 modems corresponding in number to facsimile apparatuses as broadcasting destinations, (2) an arrangement wherein transmission of image data and control signals is assigned to the facsimile modem, and reception of control signals is assigned to a plurality of V.21 demodulators corresponding in number to facsimile apparatuses as broadcasting destinations, and (3) an arrangement wherein transmission of image data and control signals is assigned to the facsimile modem, and reception of control signals is assigned to a plurality of V.21 demodulators fewer than the facsimile apparatuses as broadcasting destinations by adding a V.21 demodulator switching facility.

A telephone exchange operating on a volume controller provided with functions for inputting digitized speech data and volume control data, and converting a volume of the inputted speech data. A talker's sound inputted from a first channel has the volume converted and is outputted to a second channel for outputting a listener's sound. A volume of the speech data is converted according to a volume control data and exchanged. An augmenter for a sound level is calculated according to a reference signal sent from a first circuit to a second circuit.

Volume controller

A telephone exchange accommodates a plurality of lines in a primary group of an Integrated Services Digital Network (ISDN), as well as a plurality of extension terminals, in which a plurality of channels constitute each line. Control is performed in such a manner that the status of a line of an extension terminal when this terminal is using one channel among the plurality thereof is indicated by lighting an Light Emitting Diode (LED) in the color green, the status of a line of an extension terminal when this terminal is not using any of the plurality of channels but all of these channels are being used by other terminals is indicated by lighting the LED in the color red, and the status of a line of an extension terminal when this terminal is not using any of the plurality of channels but some of these channels are being used by other terminals is indicated by flashing the LED in the color red. The flashing period of the flashing red LED is made to differ in dependence upon the total number of channels and the number of channels in use.

A communication apparatus generates plural data representing a modulated analog wave by sequentially reading plural data representing an analog wave from a memory storing plural data, and controlling a sequence of such plural data to be read in accordance with information to be transmitted. Such a configuration is also provided in a switchboard to transmit internal information of the switchboard.

Communication apparatus for providing a modulated analog wave

A telephone system connected to an ISDN and a public service telephone network (PSTN) includes ISDN and PSTN interfaces and allows connected telephone sets to communicate with the both the ISDN and PSTN through a telephone apparatus main body. When the telephone apparatus main body becomes inoperative due to a power failure or the like, the ISDN or the PSTN is directly connected to one of the telephone sets. The connected telephone set receives operating power from the directly connected ISDN or PSTN, and can serve as a telephone set exclusively for the connected ISDN or PSTN.
