A printer has a shift register, an emission-time setting section, a laser diode, and a drive section. The register supplies the emission-time setting section with bits representing consecutive pixels including at least one black pixel. The emission-time setting section determines the period of time during which the drive section is to drive the laser diode, from the pixel patterns represented by the bits supplied from the register, and outputs an emission-time signal which represents said period of time. In response to the emission-time signal, the drive section drives the laser diode for the period of time, whereby a black pixel of a desired size is formed on a printing medium.

Printer for printing and image formed of 2-dimensionally arranged

A communication terminal equipment which allows data communication with a party terminal having a data communication rate different from that of the terminal equipment. Mask timing is set to periodically delete a synchronizing clock of the data communication rate of the communication terminal equipment on the basis of the data communication rate of the party terminal, a receive data is received from the party terminal in synchronism with the synchronizing clock and also the reception is made invalid at the mask timing, and a send data is transmitted to the party terminal in synchronism with the synchronizing clock also with the send data being added with a predetermined dummy bit at the mask timing.

Communication terminal equipment

A communication terminal apparatus connected to a communication network through a data channel for transfer of line transaction data or packet transaction data and through a signal channel for control of a call to a communication destination party. Communication terminal apparatuses are connected to the communication network and subscriber numbers are usually previously designated, as identification data, to all subscribers of the communication network and as necessary, address data (referred to as subaddresses) arbitrarily set among some of these subscribers are attached to the subscriber numbers. These subscriber numbers and subaddresses are transmitted and received through the signal channel separately from transaction data transmitted and received through the data channel. The present apparatus performs predetermined control operations, depending on whether or not the then received subscriber number (subaddress, if necessary) coincides with one of the previously registered subscriber numbers (subaddresses); the operations include:

Communication terminal apparatus

A facsimile apparatus of the type which is connected to a digital line and which has the function of automatically informing a particular destination terminal of the reception of a facsimile signal from a distant terminal. In the apparatus, identification information on a particular facsimile apparatus and a telephone number of a destination terminal are previously stored in a memory unit. During the reception of a facsimile signal, the apparatus detects an identification information of a distant terminal which is transmitted therefrom over a digital line. If it is determined that the detected identification information corresponds to the identification information stored in the memory unit, the facsimile apparatus automatically originates a call on the basis of the telephone number of the destination terminal which is stored in the memory unit and sends to the destination terminal a message stating that a facsimile signal has been received from the particular facsimile apparatus. In another form of facsimile apparatus, a telephone number of a destination terminal is previously stored in the memory unit. This form of facsimile apparatus is arranged to automatically originates, if a facsimile signal is received over a first channel of the digital line, a call on the basis of the telephone number stored in the memory unit and sends a message stating that a facsimile signal has been received to the destination terminal over a second channel of the digital line.
